Cochlear implantation surgery (CI) is considered a safe procedure and is the standard treatment for the auditory rehabilitation in patients with severe-to-profound sensorineural hearing loss. Although the development of minimally traumatic surgical concepts (MTSC) have enabled the preservation of residual hearing after the implantation, there is scarce literature regarding the vestibular affection following MTCS. The aim of the study is to analyze histopathologic changes in the vestibule after CI in an animal model (Macaca fascicularis). Cochlear implantation was performed successfully in 14 ears following MTCS. They were classified in two groups upon type of electrode array used. Group A (n = 6) with a FLEX 28 electrode array and Group B (n = 8) with HL14 array. A 6-month follow-up was carried out with periodic objective auditory testing. After their sacrifice, histological processing and subsequent analysis was carried out. Intracochlear findings, vestibular presence of fibrosis, obliteration or collapse is analyzed. Saccule and utricle dimensions and neuroepithelium width is measured. Cochlear implantation was performed successfully in all 14 ears through a round window approach. Mean angle of insertion was >270° for group A and 180-270° for group B. In group A auditory deterioration was observed in Mf 1A, Mf2A and Mf5A with histopathological signs of scala tympani ossification, saccule collapse (Mf1A and Mf2A) and cochlear aqueduct obliteration (Mf5A). Besides, signs of endolymphatic sinus dilatation was seen for Mf2B and Mf5A. Regarding group B, no auditory deterioration was observed. Histopathological signs of endolymphatic sinus dilatation were seen in Mf 2B and Mf 8B. In conclusion, the risk of histological damage of the vestibular organs following minimally traumatic surgical concepts and the soft surgery principles is very low. CI surgery is a safe procedure and it can be done preserving the vestibular structures.

Introduction: In patients with benign paroxysmal positional vertigo, BPPV; a torsional-vertical down beating positioning nystagmus can be elicited in the supine straight head-hanging position test or in the Dix-Hallpike test to either side. This type of nystagmus can be explained by either an anterior canal BPPV or by an apogeotropic variant of the contralateral posterior canal BPPV Until now all the therapeutic maneuvers that have been proposed address only one possibility, and without first performing a clear differential diagnosis between them.
Objective: To propose a new maneuver for torsional-vertical down beating positioning nystagmus with a clear lateralization that takes into account both possible diagnoses (anterior canal-BPPV and posterior canal-BPPV).
Methods: A prospective cohort study was conducted on 157 consecutive patients with BPPV. The new maneuver was performed only in those with torsional-vertical down beating positioning nystagmus with clear lateralization.
Results: Twenty patients (12.7%) were diagnosed with a torsional-vertical down beating positioning nystagmus. The maneuver was performed in 10 (6.35%) patients, in whom the affected side was clearly determined. Seven (4.45%) patients were diagnosed with an anterior canal-BPPV and successfully treated. Two (1.25%) patients were diagnosed with a posterior canal-BPPV and successfully treated with an Epley maneuver after its conversion into a geotropic posterior BPPV.
Conclusion: This new maneuver was found to be effective in resolving all the cases of torsional-vertical down beating positioning nystagmus-BPPV caused by an anterior canal-BPPV, and in shifting in a controlled way the posterior canal-BPPV cases of the contralateral side into a geotropic-posterior-BPPV successfully treated during the followup visit. Moreover, this new maneuver helped in the differential diagnosis between anterior canal-BPPV and a contralateral posterior canal-BPPV.

Objective: Flecainide is an oral class IC antiarrhythmic drug whose most common extracardiac adverse reactions are "dizziness" and "visual disturbances." We describe a case of flecainide associated- bilateral vestibulopathy and a literature review of this drug's effect on the vestibular system.
Patient: Sixty-nine-year-old man with a 3-month history of unsteadiness and dizziness after an increase in the dose of flecainide.
Interventions: Otologic examination, video head-impulse test, vestibular evoked myogenic potentials, pure tone audiometry and high-resolution magnetic resonance imaging.
Results: Otologic examination, including the head-impulse test, and vestibular testing revealed bilateral vestibulopathy.
Conclusions: Dizziness is a common extracardiac adverse reaction of Flecainide. Based on the clinical case that we present and the literature review carried out, we hypothesized that a possible mechanism by which flecainide might cause dizziness and visual disturbances is bilateral vestibulopathy.

Benign paroxysmal positional vertigo (BPPV) is one of the most common disorders that causes dizziness. The incidence of horizontal semicircular canal (HSC) BPPV ranges from 5% to 40.5% of the total number of BPPV cases diagnosed. Several studies have focused on establishing methods to treat BPPV caused by the apogeotropic variant of the HSC, namely, the Appiani maneuver (App). In 2016, a new maneuver was proposed: the Zuma e Maia maneuver (ZeM), based on inertia and gravity. The aim of this study is to analyze the efficacy of App versus ZeM in the resolution of episodes of BPPV produced by an affectation of the horizontal semicircular canal with apogeotropic nystagmus (Apo-HSC). A retrospective, quasi-experimental study was conducted. Patients attended in office (November 2014-February 2019) at a third-level hospital and underwent a vestibular otoneurology assessment. Those who were diagnosed with Apo-HSC, treated with App or ZeM, were included. To consider the efficacy of the maneuvers, the presence of symptoms and/or nystagmus at the first follow up was studied. Patients classified as A were those with no symptoms, no nystagmus; A/N+: no symptoms, nystagmus present during supine roll test; S: symptoms present. Previous history of BPPV and/or otic pathology and calcium levels were also compiled. From the 54 patients included, 74% were women. The average age was 69. Mean follow-up: 52.51 days. In those patients without previous history of BPPV (n = 35), the probability of being group A was 63% and 56% (p = 0.687) when treated with App and ZeM, respectively, while being A/N+ was 79% and 87% for App and ZeM (p = 0.508). Of the 19 patients who had previous history of BPPV, 13% and 64% were group A when treated with App and ZeM (p = 0.043), and 25% and 82% were A/N+ after App and ZeM, respectively (p = 0.021). In conclusion, for HSC cupulolithiasis, ZeM is more effective than App in those cases in which there is a history of previous episodes of BPPV (A: 64% (p = 0.043); A/N+: 82% (p = 0.021)).

Purpose: The aims of this study were to analyze and characterize the irrintzi (a folkloric shout emitted in a single breath used by the Basque people) acoustically and to describe the mechanism by which it is emitted. Method: Thirty-six sound samples of 12 female volunteers were analyzed. Acoustic analysis included primarily fundamental frequency (fo), spectral analysis in the time domain with a narrowband filter, and the use of linear predictive coding (LPC). Laryngeal and pharyngeal movements while emitting an irrintzi were studied by fiberoptic nasal endoscopy. Postural and mandible movements were observed and video recorded. Movements of the larynx and the vocal tract were also studied by lateral pharyngo-laryngeal radioscopy. Results: The central part of an irrintzi spectrogram contains a peculiar, repeated M-shaped motif unseen in the spectrogram of any other human vocal emission, and intensity was over 90 dB SPL in all cases. fo was very high (1487 Hz) especially at the end of the irrintzi. Fiberoptic nasal endoscopy consistently revealed considerable elevation of the glottis, with the larynx swinging forward and retraction of the ventricular bands. Lateral radioscopy showed a very high larynx and a high tongue dorsum. Conclusions: The irrintzi is a sound emitted in a single breath and characterized by its shrillness and loudness, qualities that make it audible in noisy environments and over large distances and the vocal technique observed when it is produced can be explained by the Estill voice model (Steinhauer et al., 2017). The use of this technique may help in the treatment of voice disorders and improve efficiency in singers, teachers, actors, and people who use their voice at high volume or at high frequency.

Background: Hearing loss causes a significant reduction in the quality of life of patients with Ménière's disease. Although speech recognition is also affected, it has not been extensively studied. The objective of the study was to describe speech recognition behavior during a prolonged period in patients with unilateral Ménière's disease.
Methods: A prospective case-control study was performed. The case group included patients with defined unilateral Ménière's disease and the control group included patients with progressive non-fluctuating hearing loss. Patients underwent an auditory evaluation periodically. Pure-tone audiometry and speech recognition tests-speech recognition threshold and speech discrimination score-were administered. The dissociation between pure-tone audiometry and speech recognition was assessed through a linear regression analysis. During follow-up, Ménière's disease patients were subdivided into a stable and fluctuating subgroup (a change of >20% in the speech discrimination score with a change no greater than 15 dB in pure-tone audiometry).
Results: The average follow-up time was 79.9 months. Fifty-seven patients were included (30 cases, 27 controls). Dissociation between puretone audiometry and speech recognition threshold began to appear in the case group after 21 months, and it was statistically significant at 108 months. Duration of the disease was the only variable studied that influenced the dissociation. The fluctuation subgroup in cluded 56.6% of the cases.
Conclusion: We described 2 audiological peculiarities in Ménière's disease patients: dissociation between pure-tone audiometry and speech recognition during the evolution of the disease and the fluctuation of speech recognition regardless of the change in pure-tone audiometry. Our results highlight the importance of performing speech recognition tests during follow-up in patients with Ménière's disease.

Purpose To describe the anatomic relationship of the lingual nerve with the lateral oropharyngeal structures. Methods An anatomic dissection of the lateral oropharyngeal wall was conducted in eight sides from four fresh-frozen cadaveric heads. Small titanium clips were placed along the lingual nerve and the most anterior and medial border of the medial pterygoid muscle. Radiological reconstructions were employed for optimal visualization; the coronal view was preferred to resemble the surgical position. The distance between the lingual nerve and the medial pterygoid muscle at its upper and lower portion was measured radiologically. The trajectory angle of the lingual nerve with respect to the pterygomandibular raphe was obtained from the intersection between the vector generated between the clips connecting the upper and lower portion of the medial pterygoid muscle with the vector generated from the lingual nerve clips. Results The mean distance from the upper portion of the medial pterygoid muscle and superior lingual nerve clips was 10.16 +/- 2.18 mm (mean +/- standard deviation), and the lower area of the medial pterygoid muscle to the lingual nerve was separated 5.05 +/- 1.49 mm. The trajectory angle of the lingual nerve concerning to the vector that describes the upper portion of the most anterior and medial border of the medial pterygoid muscle with its lower part was 43.73o +/- 11.29. Conclusions The lingual nerve runs lateral to the lateral oropharyngeal wall, from superiorly-inferiorly and laterally-medially, and it is closer to it at its lower third.

Transoral robotic surgery (TORS) for Obstructive Sleep Apnea (OSA) is a relatively young technique principally devised for managing apneas in the tongue base area. This study summarizes and presents our personal experience with TORS for OSA treatment, with the aim to provide information regarding its safety, efficacy, and postoperative complications. A retrospective study was conducted on patients undergoing TORS with lingual tonsillectomy through the Da Vinci robot. The effectiveness of the surgical procedure was assessed employing the Epworth Sleepiness Scale (ESS) and overnight polysomnography with the Apnea-Hypopnea Index (AHI). A total of 57 patients were included. Eighteen patients (31.6%) had undergone previous surgery. The mean time of TORS procedure was 30 min. Base of tongue (BOT) management was associated with other procedures in all patients: pharyngoplasty (94%), tonsillectomy (66%), and septoplasty (58%). At 6 months follow-up visit, there was a significant improvement in AHI values (from 38.62 +/- 20.36 to 24.33 +/- 19.68) and ESS values (from 14.25 +/- 3.97 to 8.25 +/- 3.3). The surgical success rate was achieved in 35.5% of patients. The most frequent major complication was bleeding, with the need for operative intervention in three cases (5.3%). The most common minor complications were mild dehydration and pain. TORS for OSA treatment appears to be an effective and safe procedure for adequately selected patients looking for an alternative therapy to CPAP.

Introduction: Cochlear implants have been able to treat some types of hearing loss, but those related to cochlear nerve impairment made it necessary to find new ways to manage these deficits; leading to auditory brainstem implants (ABI).
Aim: Our objective is to present the clinical profile of patients treated through an ABI and the results obtained from 1997 to 2017.
Material and methods: On the one hand, patients with statoacoustic nerve tumours (VIIIcranial nerve) were selected, and on the other hand, patients withoutVIII tumours with congenital malformations of the inner ear. Before and after the placement of the ABI, hearing was assessed through tonal audiometry, from which the PTA (Pure Tone Average) and the CAP (Categories of Auditory Performance) scale were obtained.
Results: A total of 20 patients undergoing ABI surgery were included. Eight were of tumour cause (40%) and 12 non-tumour (60%). In 15 subjects (75%) a suboccipital approach was performed and in 5 (25%) translabyrinthine. The mean of active electrodes before the implantation of Cochlear® (Nucleus ABI24) was 13/21 (61.90%) versus 8.5/12 (70.83%) of the Med-el® (ABI Med-el). An improvement in the mean PTA of 118.49dB was found against 46.55dB at 2years. On the CAP scale, values of1 were obtained in the preimplantation and of 2.57 (1-5) in the 2-year revision.
Conclusion: The ABI is a safe option, and with good hearing results when the indication is made correctly.

Purpose To compare the surgical and audiological outcomes with two perimodiolar electrode arrays (Nucleus 512-Contour Advance (R) y Nucleus 532-Slim Perimodiolar (R)) and a straight electrode array (Nucleus 422/522). Methods Patients were retrospectively selected from our cochlear implant program database. Only patients with a history of bilateral, sensorineural postlingually profound hearing loss who underwent cochlear implant surgery with either a N512, a N532 or a N422 were included. Throughout a year of follow-up, pure tone audiometry (PTA), speech perception, Impedances and T-C Thresholds levels were analyzed. Surgical data were also analyzed. Results 66 patients were included (19-CI532, 20-CI512 and 27-CI422). The most common type of cochlea access with the N532, N512 and N422 was through an extended round window, a promontorial cochleostomy and a pure round window, respectively. No significant differences were observed after 12 months in Mean PTA and Speech recognition. No significant differences were seen in the levels of hearing preservation at frequencies of 250 and 500. The average values of the impedances were significantly higher in the CI group N532 and N422 than in the N512. The mean values of the T and C levels were significantly lower in the CI groups N532 and N422 compared with the N512. Conclusions No significant differences were observed after 12 months in Mean PTA and Speech recognition; however, a faster acquisition of auditory results were observed in the group of patients treated with the CI N532. The type of electrode array influences in the type of cochleostomy.

Objective: The aims of this study were to test the hypothesis that greater supraglottic compression (anteroposterior or lateral) correlates with higher subglottic pressure (SGP) and to develop a classification of muscle tension dysphonia (MTD), based on the degree of supraglottic compression during speech. Method: A prospective, cross-sectional study was conducted in a series of 37 consecutive patients diagnosed with MTD with an altered aerodynamic profile characterized by high SGP (more than 90 mmH(2)O). Supraglottic anteroposterior and lateral compression were categorized in three grades and assessed during the laryngoscopic examination. All patients completed the Spanish Voice Handicap Index (VHI) questionnaire and completed an acoustic and aerodynamic voice assessment. The relationship between compression grade and VHI with SGP was analyzed. Results: More than 90% of patients demonstrated some degree of anteroposterior compression, and 67% had some degree of lateral compression. The mean (SD) SGP was 111.03 (16.7) mmH(2)O, and the mean VHI was 27.86 (12.5). The degree of SGP was statistically different in the different grades of anteroposterior compression, and also anteroposterior compression correlated with an SGP (p < .05). The degree of lateral compression was not correlated with SGP. Neither the degree of anteroposterior or lateral compression nor the value of SGP was found to correlate with VHI. Conclusions: Because grade of anteroposterior compression correlates with SGP, these grades can be used for diagnosis and follow-up of MTD patients. To this end and on this basis, we propose a new classification for MTD. Unlike the established classification, our proposed one makes it possible to combine different laryngoscopic features, improving the description of the larynx during phonation.

We present a case report of a 25-year-old male patient who was complaining about a sensation and noise described as a ''sponge crunching'' in the right preauricular region and right ear that was more noticeable when inflating the cheeks. Under the clinical suspicion of a pneumoparotid case, a CT scan was performed. The study revealed the presence of air in the ductal system and within the gland. The patient was diagnosed with pneumoparotid and was treated conservatively. Herein, we review the literature and discussion the management of this uncommon condition. © 2020

Purpose Since the beginning of cochlear implant (CI) surgery, several techniques to fixate the electrode array at the cochleostomy and stabilize it have been described; however, most techniques use autologous tissues such as fascia, muscle, fat or fibrin glue. We describe a new surgical technique aimed to stabilize the electrode array of a CI without using autologous tissues or artificial materials. Materials and methods The surgical technique described consists in creating three stabilizing channels in the temporal bone for the electrode array. The first one in a partially opened aditus, the second one in a partially preserved Koerner's septum (KS) and the last one in the sinodural angle. The procedure was performed in five human temporal bones using a straight array; a radiography was made to confirm the correct placement of the electrode array and afterwards all temporal bones were shaken using a Titramax 1000 platform. The correct placement of the array post-shaking was then confirmed using the microscope and another radiography. Results No migration of the electrodes outside the cochlea was observed. The CI cable remained in the same position at the aditus and the KS in all the temporal bones. In three cases (60%), the electrode array moved away from the groove carved in the sinodural angle. Conclusions The new surgical technique described stabilizes the electrode array using the temporal bone's normal anatomy, preserving the middle ear spaces, facilitating the ulterior explantation and reimplantation if necessary, and may reduce cost and surgery time.

Introduction Chronic rhinosinusitis (CRS) is a highly prevalent pathology in our society. Due to the prevalence of this condition and to the persisting symptoms despite an appropriate medical treatment, surgical techniques are often required. Lately, minimal invasive techniques have been described, such as lacrimal diversion devices (LDDs). This technique offers a fast and convenient choice for delivery of sinus irrigation and topical medication. Objective We aimed to describe our experience with LDDs and evaluate the safety and effectiveness of the procedure in patients with moderate to severe CRS without nasal polyposis (CRSsNP) and persistent symptomatology despite medical therapy. Methods A total of 7 patients underwent bilateral lacrimal stents placement in the operating room. A retrospective observational study was conducted. The Sino-Nasal Outcome Test-20 (SNOT-20) survey was performed and the score obtained was compared before and 1month after the procedure. Results The LDDs were used for an average of 80 days. During the follow-up, only three patients had a mild complication with the device (granuloma in the punctum, obstruction, and early extrusion). The mean baseline SNOT-20 score dropped significantly ( p =0.015) from 25.85 to 11.57 (mean: - 14.29) 1month after the procedure. Conclusion According to our experience and results, the use of LDD is a novel, feasible, and less invasive technique to treat refractory CRS. It reduces the risk of mucosal stripping, provides short-term outcomes, and the surgical procedure does not require advanced training in endoscopic sinus surgery. Moreover, it can be performed in-office under local anesthesia or sedation.

The objective of this communication is to describe our preliminary results in upper airway stimulation surgery via hypoglossal nerve stimulation implantation for obstructive sleep apnoea. We describe 4 cases and the outcomes of the surgery were analysed using the Epworth scale, apnoea-hypopnoea index, minimal 02 Sat, average 02 Sat and snoring intensity. In all cases a significant reduction in Epworth scale values and apnoea-hypopnoea index were obtained (P<.05). The minimum and average oxygen saturation had better values after the surgery, however, there was no statistically significant difference. The snoring severity measured subjectively changed from "intense" to "absent", in all cases. The preliminary results obtained with the upper airway stimulation surgery via hypoglossal nerve stimulation showed objective and subjective improvement after the implant activation.

Different types of otic capsule dehiscence restricted to the cochlea have been described. Here we describe the case of a patient with a cochlear-internal auditory canal dehiscence associated with a cochlear-facial dehiscence not reported before. A 53-year-old patient with severe to profound sensor ineural hearing loss due to bilateral Meniere's disease under went a cochlear implant surgery on the right ear. Preoperative brain magnetic resonance imaging findings were reported to be normal; dur ing surgery, a cerebrospinal fluid gusher occur red at the time of round window opening. Postoperative computed tomography imaging showed a bony dehiscence at two levels of the otic capsule.

Objectives: To describe the level of knowledge and perception of tuberculosis among public transport workers attending Road Safety Education courses in Lima, Peru.
Methods: An observational, cross-sectional, analytic study was conducted between July and August 2014 in public transport workers attending the courses of Road Safety education. In Lima, such courses are mandatory for workers in the public transport area. An anonymous and voluntary survey was applied to obtain the following variables: sociodemographic characteristics, history of tuberculosis, tuberculosis knowledge and attitudes towards the disease. The factors associated to the risk perception of Tuberculosis infection were analysed using Poisson regression.
Results: From 309 attendees, 216 surveys were analysed (69.9%). Of these, 88.4% were males, 3.2% had a history of tuberculosis. The most widely known symptom was cough with phlegm (44.4%), the most popular source of information was television (39.8%), and only 9.7% had any training about tuberculosis. A 41.2% of respondents believed that working in the public transport sector was an occupation with a high risk of tuberculosis infection. No significant association between risk perception of tuberculosis and sociodemographic characteristics was found.
Conclusion: A considerable lack of knowledge about tuberculosis symptoms and a low perception of risk for tuberculosis exists among public transport workers in Lima. Education strategies directed to this population need to be implemented.

In order to determine the association between the number of formal urban public transport routes and the situation of tuberculosis (TB) in each district of Lima, a correlational analysis and linear regression model between the two variables was performed. Also determined were the number of public transport routes most likely to transmit TB, the areas of greatest activity of these routes and a mapping of these routes. There is a positive correlation between the number of formal routes through each district of Lima and the situation of tuberculosis; a percentage of the TB situation could be explained by the number of public transport routes. Of the 404 formal routes that run through Lima, 147 (36.4%) are routes of greater probability of transmission of TB. Public transport should be considered in the ongoing fight against TB.
