Transoral Flexible Laser Surgery of the Larynx with Blue Laser.

INTRODUCTION: Laser surgery of the larynx is currently the standard of clinical practice in a multitude of procedures. Lasers with photoangiolytic properties have a wide application in endolaryngeal lesions. One of their most prominent features is the ability to coagulate blood vessels, reducing unwanted tissue damage. Our objective is to expose the uses of the blue laser (445 nm) in the larynx. MATERIAL AND METHODS: A retrospective study was carried out including 47 patients treated with blue photoangiolytic laser from October 2021 to January 2023 at a university hospital. Demographic data, type of lesion presented, date of intervention and scope of the procedure, as well as the parameters of the laser used, were recorded. The number of sessions received per patient, the result and complications were also collected. RESULTS: A total of 47 patients with laryngeal lesions were treated, including vascular angiomas, laryngeal sulcus vocali, vocal cord polyps, Reinke's edemas, laryngeal papillomatoses, subglottic stenosis, laryngeal synechiae, subglottic granulomas, glottic scars, vocal fold leukoplakias, laryngeal dysplasias and tracheostomal granulomas. The mean age was 52.5 years, and 64.3% of the patients were women. The range of power used in the resective surgeries was 2-10 Watts with a 20-millisecond window. The average number of sessions received was 2.1 (range 1-4). A satisfactory situation was obtained in 45 of the 47 patients treated (95.75%), and an evident decrease in lesions was seen in the remaining two. There was no evidence of any complications directly derived from the use of the blue laser. Twenty-seven cases (54%) were treated exclusively in-office. CONCLUSIONS: The blue laser is safe and effective in the treatment of a wide range of laryngeal pathologies. Its advantages include its portability, its photoangiolytic qualities as well as its ability to vaporize tissue in contact mode, which can treat subepithelial vessels or resect lesions.

Segundos tumores primarios y sus factores de riesgo en pacientes con tumores índice de cabeza y cuello / Second primary tumors and their risk factors in patients with primary head and neck tumors

Introducción y objetivo: El término de segundo tumor primario (STP) es utilizado para designar un nuevo cáncer primario que se presenta en una persona a la que se le ha diagnosticado un cáncer previamente. Se considera que los STP se producen de forma independiente y no como resultado de un resurgimiento o metástasis del tumor índice o primer tumor primario (PTP). El objetivo de este estudio es investigar la prevalencia, factores de riesgo, localización y tratamiento de los STP, así como el tiempo transcurrido entre la aparición de los tumores. Método: Se realiza un estudio retrospectivo descriptivo con pacientes con diagnóstico de STP entre enero del 2004 y diciembre de 2021 en el Hospital Universitario de Fuenlabrada. Se analizó la prevalencia y localización de los STP, los factores de riesgo relacionados, el tiempo entre la aparición del PTP y el STP, el tratamiento del PTP y STP y su resultado. Resultados: Del total de 360 casos del registro de tumores, 73 pacientes (20,2%) fueron incluidos en el estudio por padecer un STP. De los participantes, el 75% eran fumadores y el 46,6% bebedores. La mayor parte de estos pacientes fueron tratados quirúrgicamente. Se observó que el PTP con mayor desarrollo de STP fue el de cáncer de laringe, siendo la supraglotis la sublocalización más frecuente. El STP más frecuente fue el carcinoma epidermoide de pulmón. Conclusiones: En nuestra serie los STP aparecen en el 20% de los pacientes con tumores índice de cabeza y cuello. Son más frecuentes tras el cáncer de laringe, siendo la localización más frecuente el pulmón. Tanto el tabaco como el alcohol juegan un papel importante en su desarrollo, acortando el tiempo entre la aparición de los tumores, además de poder aparecer recidivas, persistencias y metástasis. (AU)

Introduction and objective: The term second primary tumor (SPT) is used to designate a new primary cancer that occurs in a person previously diagnosed with cancer. SPT are considered to occur independently and not as a result of a resurgence or metastasis of the index tumor or first primary tumor (FPT). The aim of this study is to investigate the prevalence, risk factors, location and treatment of STP, as well as time elapsed between tumor occurrence. Method: A retrospective descriptive study was performed including patients diagnosed with SPT between January 2004 and December 2021 at Hospital Universitario de Fuenlabrada. The prevalence and location of SPT, related risk factors, time between the onset of FPT and SPT, treatment of FPT and SPT and their outcome were analyzed. Results: From a total of 360 cases, 73 patients were included in the study because of SPT. 75% were smokers and 46.6% were drinkers. Most of these patients were treated surgically. It was observed that the FPT with the highest development of SPT was the larynx, with supraglottis being the most frequent sublocalization. The most frequent SPT was epidermoid carcinoma of the lung. Conclusions: In our series SPT appear in 20% of head and neck tumors. They are more frequent after laryngeal cancer, the most frequent location being the lung. Both tobacco and alcohol play an important role in their development, shortening the time between the appearance of tumors, in addition to the possibility of recurrence, persistence and metastasis.

Laryngotracheal Complications after Intubation for COVID-19: A Multicenter Study.

Many of the patients with COVID-19 have suffered respiratory distress requiring prolonged endotracheal intubation (ETI) resulting in laryngotracheal complication with an impact on breathing, phonation, and swallowing. Our aim is to describe laryngeal injuries diagnosed after ETI in patients with COVID-19 in a multicentre study. METHODS: A prospective descriptive observational study was conducted from January 2021 to December 2021, including COVID-19 patients with laryngeal complications due to ETI diagnosed in several Spanish hospitals. We analyzed the epidemiological data, previous comorbidities, mean time to ICU admission and ETI, need for tracheostomy, mean time on invasive mechanical ventilation until tracheostomy or weaning, mean time in ICU, type of residual lesions, and their treatment. RESULTS: We obtained the collaboration of nine hospitals during the months of January 2021 to December 2021. A total of 49 patients were referred. Tracheostomy was performed in 44.9%, being late in most cases (more than 7-10 days). The mean number of days of ETI until extubation was 17.63 days, and the main post-intubation symptoms were dysphonia, dyspnea, and dysphagia, in 87.8%, 34.7%, and 42.9%, respectively. The most frequent injury was altered laryngeal mobility, present in 79.6%. Statistically, there is a greater amount of stenosis after late ETI and after delayed tracheostomy, not observing the data with the immobility alterations. CONCLUSION: The mean number of days of ETI was long, according to the latest guidelines, with the need for several cycles of pronation. This long ETI may have had an impact on the increase of subsequent laryngeal sequelae, such as altered laryngeal mobility or stenosis.

Tratamiento quirúrgico de la patología tumoral de la glándula parótida. Estudio descriptivo de 263 parotidectomías / Surgical treatment of tumor pathology of the parotid gland. Descriptive study of 263 parotidectomies

Introducción y objetivo: Los tumores salivales representan el 3-10% de los tumores de cabeza y cuello, siendo el 75-80% de origen parotídeo y en su mayoría benignos. La parotidectomía es una técnica quirúrgica que consiste en la exéresis de la glándula parótida. Existen diversos tipos; parotidectomía superficial (PS), parotidectomía superficial parcial (PSP) y parotidectomía total (PT). En esta última, al no respetarse el nervio facial (NF), las complicaciones son más frecuentes. Nuestro objetivo es analizar el resultado (tasa de recidiva y complicaciones) de la parotidectomía como técnica quirúrgica empleada en el manejo de la patología parotídea, así como evaluar qué prueba complementaria es la más eficaz en el diagnostico prequirúrgico de la patología parotídea tumoral. Material y método: Se realiza un estudio retrospectivo incluyendo 263 pacientes tratados mediante PS o PT entre enero de 2004 y diciembre de 2020 en el Hospital Universitario de Fuenlabrada. Se registraron datos demográficos, tiempo de evolución de la lesión, pruebas complementarias, protocolo quirúrgico y complicaciones postoperatorias. Se analiza principalmente la correlación positiva entre las pruebas realizadas prequirúrgicas (PAAF, ecografía, TC y RMN), con el diagnóstico definitivo anatomopatológico obtenido tras examinar la pieza quirúrgica. También se describe la tasa de paresia y parálisis facial y otras complicaciones habidas. Resultados: Se incluyeron 263 pacientes tratados mediante parotidectomía. El tiempo de evolución medio de las lesiones parotídeas fue de 15 meses (DE 19.88). La sensibilidad de la PAAF en nuestro estudio fue de 68.7%. Se realizó ecografía en un 44.10% de los pacientes, TC en un 77.94% y RMN en un 15.20%, mostrando una sensibilidad de 18.05%, 31.21% y 45%, respectivamente. (AU)

Introduction and objetive: Salivary tumors account for 3-10% of head and neck tumors, 75-80% being of parotid origin and mostly benign. Parotidectomy is a surgical technique that consists of exeresis of the parotid gland. There are various types; Superficial parotidectomy (PS), partial superficial parotidectomy (PSP), and total parotidectomy (PT). In the latter, since the facial nerve (FN) is not spared, complications are more frequent. Our objective is to analyze the outcome (recurrence rate and complications) of parotidectomy as a surgical technique used in the management of parotid pathology, as well as to evaluate which complementary test is the most effective in the pre-surgical diagnosis of tumorous parotid pathology. Material and methods: We performed a retrospective study including 263 patients treated by SP or TP between January 2004 and December 2020 at the Fuenlabrada University Hospital. Demographic data, time of lesion evolution, complementary tests, surgical protocol and postoperative complications were recorded. The positive correlation between the pre-surgical tests performed (Fine needle aspiration (FNA), ultrasound, CT and MRI) and the definitive anatomopathological diagnosis obtained after examining the surgical specimen is analyzed. The rate of paresis/facial paralysis and other complications is also described. Results: We included 263 patients treated by parotidectomy. (AU)

Persistent Dysphonia in Hospitalized COVID-19 Patients.

INTRODUCTION: The main objective of this study is to estimate the prevalence of persistent dysphonia in hospitalised COVID-19 patients. METHODS: Data were collected from those COVID-19 patients who, during the months of March to April 2020, were hospitalised in ward or intensive care unit at the University Hospital of Fuenlabrada. Patients with dysphonia prior to SARS-CoV-2 were excluded. Informed consent was obtained orally by a telephone call, as well as clinical and epidemiological data. Patients who reported persistent dysphonia were assessed using the Voice Handicap Index 10, the maximum phonation time, the s/z ratio and a fibrolaryngoscope examination. Patients who reported persistent dysphagia were assessed with the Eating Assessment Tool 10. RESULTS: A total of 79 patients were included in the study (48 men and 31 women). 10 ICU patients (25%) and 4 ward patients (10,3%) had dysphonia at least 3 months after hospital discharge, but no association was found between ICU admission and the presence of persistent dysphonia (P = 0.139). Persistent dysphonia in patients admitted to the ICU is associated with persistent dysphagia (P = 0.002), also the age of patients with persistent dysphonia is significantly higher than the age of non-dysphonic patients (P = 0.046). The most frequent exploratory finding was vocal cord paresis/paralysis (60.4%). CONCLUSION: This is one of the first studies to show that persistence of dysphonia may be a consequence of COVID-19, so further studies are needed to assess the evolution and prognosis of these patients and the possible association of dysphonia with the severity of the disease.

Endoscopia bajo sueño inducido en la apnea obstructiva del sueño (DISE). Estudio comparativo entre las clasificaciones NOHLy VOTE / Drug Induced Sleep Endoscopy (DISE). A comparative study between NOHL and VOTE classifications

Introducción y objetivo: Varias clasificaciones han sido propuestas para expresar los resultados de la endoscopia bajo sueño inducido (DISE) en la apnea obstructiva del sueño (AOS), pero ninguna está globalmente aceptada. El objetivo del estudio es analizar las clasificaciones más utilizadas: NOHL y VOTE, para valorar cuál de ellas aporta más ventajas.Método: Se diseñó un estudio de cohortes prospectivo de 100 pacientes a los que se les realizó una DISE por AOS. Tres otorrinolaringólogos evaluaron de forma ciega los videos de las DISE y codificaron los resultados de acuerdo a las escalas NOHL y VOTE, anotando qué hallazgos determinaban la indicación de cirugía.Resultados: Según el investigador principal, en un 64% se indicó cirugía de un solo nivel, de estos, el paladar fue el más predominante, en el 26% se indicó cirugía multinivel y en un 10% se desestimó cirugía. La concordancia global para expresar los resultados de la DISE según las escalas NOHL y VOTE, en cuanto al grado de obstrucción es moderada / regular a nivel de la epiglotis (k = 0,467) y baja en el resto de estructuras (k = 0,097).Discusión: A pesar de que el grado de acuerdo interobservador es similar en ambas escalas, para VOTE es ligeramente superior.Conclusiones: La DISE es una prueba segura, reproducible y fácil de realizar. Recomendamos el uso de la escala VOTE porque ha demostrado tener un grado de acuerdo interobservador superior, es la escala más utilizada en la literatura y la recomendada en los documentos de consenso. (AU)

Introduction and objective: There is no standardized method to express DISE results. Several classifications have been proposed, but none are globally accepted. The objective of this study is to analyze the most used classifications: NOHL and VOTE to assess which of them provides more advantages. Method: A prospective cohort study of 100 patients who underwent DISE was carried out. Three otolaryngologists blindly evaluated the DISE videos and coded the results according to the NOHL and VOTE scales and at what level surgery was indicated. Results: According to the main researcher, in 64% of patients, surgery of only one level was indicated, being the palate the predominant level, followed by a 26% where multilevel surgery was indicated, and in 10% no surgery was indicated. The global agreement to express the DISE results according to the NOHL, VOTE scales regarding the degree of obstruction is moderate / regular at the level of the epiglottis (k = 0.467) and low in the rest of the structures (k = 0.097). Discussion: Although the degree of interobserver agreement is similar in both scales, for VOTE it is slightly higher. Conclusions: DISE is a safe, reproducible and easy to perform test. We recommend the use of the VOTE scale because it has been demonstrated to have a higher degree of interobserver agreement, it is not only the most widely used scale, but also recommended in consensus documents.

Autologous Adipose Tissue Injection of Vocal Cords in Presbyphonia.

OBJECTIVE: This series evaluates the long-term results of autologous adipose injection (AAI) in patients older than 65 years with presbyphonia. STUDY DESIGN: Retrospective cohort study. SETTING: Academic secondary medical center. METHODS: This was a retrospective study with a minimum follow-up of 12 months. All patients underwent AAI for atrophy of both vocal folds due to presbyphonia. We measured subjective parameters as Voice Handicap Index-10 (VHI-10) or GRBAS scale (grade, roughness, breathiness, asthenia, strain) and objective measures such as maximum phonation time (MPT) or square pixel closure defect. We reviewed the medical records of patients undergoing AAI during the 2011-2018 period. An analysis of the demographic variables of the group was performed, as well as the values of VHI-10, GRBAS, and MPT, and the minimum closure defect measured in square pixels and the number of closed frames in the glottal cycle before and after the intervention. RESULTS: At 12 months, 17 of 18 patients reported subjective and VHI-10 improvement. The mean preoperative VHI-10 (26.7) was significantly higher than the postoperative value (14.4), and the GRBAS scale had a preoperative mean of 8.7 and a postoperative mean of 4.3, both with statistical significance. MPT increased from 7.7 to 12.4 seconds (P < .0001). The minimum closure defect measurements obtained in square pixels changed from 305 to 124, achieving complete closure in 3 patients. The closed phase of the glottal cycle change from 14.3% to 38.2% after the AAI. CONCLUSIONS: AAI improves long-term vocal fold closure, demonstrating utility in patients with presbyphonia.

Timing of elective tracheotomy and duration of mechanical ventilation among patients admitted to intensive care with severe COVID-19: A multicenter prospective cohort study.

BACKGROUND: Optimal timing for tracheotomy for critically ill COVID-19 patients requiring invasive mechanical ventilation (IMV) is not established. METHODS: Multicenter prospective cohort including all COVID-19 patients admitted to intensive care units (ICUs) in 36 hospitals who required tracheotomy during first pandemic wave. With a target emulation trial framework, we studied the causal effects of early (7-10 days) versus late (>10 days) tracheotomy (LT) on time from tracheotomy to weaning, postoperative mortality, and tracheotomy complications. RESULTS: Of 696 patients, 20.4% received early tracheotomy (ET). ET was associated with faster weaning (hazard ratio [HR] [95% confidence interval, CI]: 1.25 [1.00-1.56]) without differences in mortality (HR [95% CI]: 0.85 [0.60-1.21]) or complications (adjusted rate ratio [95% CI]: 0.56 [0.23-1.33]). CONCLUSIONS: ET had a similar or lower post-tracheotomy weaning time than LT, potentially shortening IMV and ICU stays, without changing complication or mortality rates in COVID-19 patients.

Influence of Upper Airway Surgery on Voice and Speech Recognition.

PURPOSE: Upper airway surgery comprises a set of techniques that modify the anatomy of the vocal tract, including tonsillectomy and septoplasty. The objective of this work is to study the changes in acoustic parameters and the effects on the identification or verification of the speaker through the speech produced after the vocal tract surgeries, comparing them with a control group. METHODS: A prospective study was performed between January 2019 and June 2019 including. The final study sample consisted of 84 patients who met the inclusion criteria. Of these, 31 underwent septoplasty, 26 tonsillectomy patients, and 27 controls. Demographic data and GRBAS evaluation were statistically evaluated. Tests were taken before surgery, 2 weeks after surgery and 3 months later. Furthermore, to establish the equal error rate, the recording of patients' voices was made with a succeeding acoustic analysis and programmed identification of the speaker through machine learning systems. RESULTS: A significant variance was observed in GRBAS, after surgery. Regarding acoustic parameters, a greater change was observed in the fundamental frequency at 2 weeks after surgery in the tonsillectomy group. Formants (F1-F3) and antiformants (AntiF1-AntiF3) changed in septoplasty group, not in tonsillectomy and control group at 3 months. When studying the impact of voice changes on the verification of the speaker through the speech, it was observed that there was a greater error in recognition in the tonsillectomy group at 2 weeks, coinciding with the results obtained in the rest of the parameters studied. CONCLUSIONS: Results suggest that upper airway surgery produces modifications in the vocal tract affecting GRBAS, acoustic parameters, including formants and antiformants, producing an effect on verification of the speaker through the speech.

Effect of Functional Endoscopic Sinus Surgery on Voice and Speech Recognition.

OBJECTIVE: Functional Endoscopic Sinus Surgery (FESS) is the surgery of choice for nasal polyposis and chronic rhinosinusitis. The aim of our study is to assess the influence of this surgery in the acoustic parameters of voice, and their implications in the systems of identification or verification of the speaker through the speech. MATERIAL AND METHODS: A prospective study was performed between January 2017 and June 2017 including two groups of patients: those undergoing FESS, and a control group. Demographic data and GRBAS assessment were statistically analyzed. In addition, a recording of patients' voices was made with a subsequent acoustic analysis and automatic identification of the speaker through machine learning systems, establishing the equal error rate. Samples were taken before surgery, 2 weeks after surgery and 3 months later. RESULTS: After FESS, a significant difference was observed in Grade, Roughness, Breathiness, Asthenia, Strain (GRBAS). Besides, acoustic analysis showed a significance decrease in fundamental frequency (F0), when compared with the control group. For the automatic identification of the speaker through computer systems, we found that the equal error rate is higher in the FESS group. CONCLUSIONS: Results suggest that FESS produce a decrease of F0 and changes in the vocal tract that derive in an increase in the error of recognition of the speaker in FESS patients.

Open Tracheostomy for Critically Ill Patients with COVID-19.

BACKGROUND: COVID-19 is a worldwide pandemic, with many patients requiring prolonged mechanical ventilation. Tracheostomy can shorten ICU length of stay and help weaning. Aims/Objectives. To describe the long-term evolution of the critically patient with COVID-19 and the need for invasive mechanical ventilation and orotracheal intubation (OTI), with or without tracheostomy. Material and Methods. A prospective study was performed including all patients admitted to the ICU due to COVID-19 from 10th March to 30th April 2020. Epidemiological data, performing a tracheostomy or not, mean time of invasive mechanical ventilation until tracheotomy, mean time from tracheotomy to weaning, and final outcome after one month of minimum follow-up were recorded. The Otolaryngology team was tested for COVID-19 before and after the procedures. RESULTS: Out of a total of 1612 hospital admissions for COVID-19, only 5.8% (93 patients) required ICU admission and IOT. Twenty-seven patients (29%) underwent a tracheostomy. After three months, within the group of tracheotomized patients, 29.6% died and 48.15% were extubated in a mean time of 28.53 days. In the nontracheostomized patients, the mortality was 42.4%. CONCLUSIONS: Tracheostomy is a safe procedure for COVID-19 and helps weaning of prolonged OTI. Mortality after tracheostomy was less common than in nontracheostomized patients.

Intratympanic steroids for combined treatment of idiopathic sudden hearing loss: when is it too late?

Background: Idiopathic sudden sensorineural hearing loss (ISSNHL) requires early treatment. Objective: To describe our experience on intratympanic steroid treatment (ITS) of ISSNHL analyzing the delay to start therapy as prognostic factor. Material and methods: We perform a retrospective study on ISSNHL treated with systemic steroids without full recovery on PTA (pure tone average) according to Siegel criteria. They were divided into two different groups: one group that additionally received ITS as combined therapy (treatment group), and another without it (control group). We analyzed the hearing recovery at 6 months and 2 years, and the influence of the delay to start ITS in the recovery. Results: After ITS was added, further complete recovery was achieved in 10 patients of the treatment group. After 6 months, PTA improvement in the treatment group was 10.84 dB, compared to 1.13 dB in the control group (p<.0001). Nevertheless, patients starting such combination of oral steroids and ITS within 8 days of diagnosis had an additional gain of 15 dB in the first 6 months, that increased to 19.17 dB after 24 months (p<.022). Conclusions: When ITS was added within the first 8 days, a significantly better and more stable response was obtained.

Effect of Septoplasty On Voice Performance: Nasalance and Acoustic Study.

BACKGROUND: Septoplasty is a surgical technique for the correction of the nasal septum that may alter the vocal tract. The aim of our study is to assess whether this technique modifies nasalance and acoustic parameters, and their clinical implications in voice perception. METHODOLOGY: A prospective study was performed between January 2017 and June 2017 including 2 groups of patients: those undergoing septoplasty, and a control group. Subjective nasality questionnaire, objective nasalance with nasometer, and GRBAS (Grade, Roughness, Breathiness, Asthenia, Strain) assessment were statistically analysed. In addition, a recording of patients' voices was made with a subsequent acoustic analysis. Samples were taken: pre-surgically, 2 weeks after surgery and after 3 months. RESULTS: After septoplasty, a significant difference was observed in GRBAS, nasality questionnaire and nasometer nasalance, when compared with the control group. As for the acoustic analysis, no differences were observed in most parameters (F0, Jitter, Shimmer, HNR, NHR, Formants F1-F3), except for the antiF3 antiformant, which showed significant changes in all the vowels studied. CONCLUSIONS: Septoplasty can produce changes in the vocal tract, with an increase in initial nasalance but with subsequent normalization. Besides, minor changes were found in the acoustic analysis but with no clinical relevance.

Improved Mucosal Wave in Unilateral Autologous Temporal Fascia Graft in Sulcus Vocalis Type 2 and Vocal Scars.

OBJECTIVES/HYPOTHESIS: We analyzed the results of 10 patients treated by unilateral autologous temporal fascia graft, comparing the pre and post surgery results, as well as the appearance of the wave and the intervals until the re-appearance of it. STUDY DESIGN: Retrospective, clinical case series. METHODS: Subjective and objective evaluation was preoperatively and postoperatively performed, using laryngovideostroboscopy, the Voice Handicap Index-10, GRBAS (grade, roughness, breathiness, asthenia, and strain), harmonics to noise ratio, Jitter, Shimmer, phonatory range, maximum phonation time, and S/Z ratio in all patients. Postoperative visits were scheduled after 1 week, 1 month, at 3 months, and at 6 months after the surgery. RESULTS: After surgery, we found significant differences in the maximum phonation time and the S/Z ratio (P <0.05). Most parameters of GRBAS also improved significantly, both in general and in the subscales, except for Breathiness and Asthenia (P <0.05). There was an average decrease in Voice Handicap Index-10 of 11.2 (P <0.05). At laryngovideostroboscopy, the mucous wave reappeared in all patients treated 1 month after surgery, and increased in amplitude until 6 months postoperative.

Balanced (endoscopic medial and transcutaneous lateral) orbital decompression in Graves' orbitopathy.

BACKGROUND: To determine the clinical outcomes and morbidity of endoscopic medial wall combined with transcutaneous lateral orbital wall decompression in Graves' orbitopathy. METHODOLOGY: A retrospective noncomparative case series of patients who underwent surgical decompression for Graves' orbitopathy at Hospital Universitario de Fuenlabrada between 2004 and 2014 was performed. We reviewed the patients' charts and analyzed before and after the decompression, the visual acuity (Snellen chart), optic nerve compression (fundoscopy and optic coherence tomography), exophthalmometry (Hertel measurement), ocular motility, diplopia, eyelid surgery needed after decompression and its possible complications. RESULTS: A total of 20 patients (36 orbits) were operated. The mean follow-up was 44 months (range 18-84). Vision improved dramatically in all compressive optic neuropathy cases (5 cases). Hertel measurements improved on average 3.5 mm (range 1.5-4.5). Diplopia was cured in eight patients (40%) and nine patients with severe preoperative diplopia required strabismus surgery after decompression. Eyelid surgery was further needed in 13 patients. Hyaluronic acid injection was the most used technique for the treatment of eyelid retraction (6 out of 13 patients). Only two major complications were observed: one case had a major post-operative epistaxis and another a cerebrospinal fluid leak. Both were resolved without further sequelae. CONCLUSIONS: These results suggest that endoscopic medial wall combined with transcutaneous lateral wall orbital decompression is an effective and safe treatment for the symptomatic dysthyroid eye disease with important proptosis or compressive optic neuropathy.

Amplitude of Glottal Mucosal Wave After Vocal Fold Microflap With or Without Fibrin Glue.

INTRODUCTION: The vocal fold microflap technique is the ideal to remove benign vocal fold pathology. Our objective is to compare the amplitudes of the mucosal wave before and after the closure of microflap defect with fibrin glue, and when microflap is left to heal by secondary intention. MATERIALS AND METHODS: The present study is a retrospective series, including 32 patients treated by intracordal phonosurgery, with closure of the microflap either with fibrin glue or by healing by secondary intention. They all had both preoperative and 6-month postoperative track records to allow voice analysis, a subjective Voice Handicap Index 10 (VHI-10), and a good image quality strobe. RESULTS: After selecting the patients was found that the mean overall preoperative VHI-10 was 26.6, and improved up to 10.5 after surgery, a statistical differences (P = 0.03). When comparing both groups, with or without fibrin glue, fibrin glue did not improved results in VHI-10. On the contrary, there was a significant difference in the improvement of the open glottal phase after surgery (P = 0.03), showing a much higher improvement when fibrin glue was used. CONCLUSIONS: The use of fibrin glue after a vocal fold microflap for advanced pathology, such as sulcus vocalis in pocket, vergeture, or vocal fold scar, increases the amplitude of the mucosal wave of the vocal folds, but does not improve the VHI-10 results in our cohort of female patients. So far, patient-reported outcome shows that healing by secondary intention continues to provide excellent voice results.

Sordera súbita: encuesta nacional en España / Sudden hearing loss: National survey in Spain

Introducción: El objetivo de nuestro estudio es identificar las actitudes diagnósticas y terapéuticas que se llevan a cabo en los diferentes servicios de otorrinolaringología (tanto del ámbito privado como público) en España con respecto a la sordera súbita. Esto permitirá establecer una base que ayude a generar un nuevo consenso a nivel nacional, unificando criterios para el tratamiento, diagnóstico y seguimiento de esta patología. Material y métodos: Se realizó una encuesta anónima por Internet, dirigida a otorrinolaringólogos españoles a nivel nacional (n = 2.029 especialistas afiliados a la SEORL), recopilando en 33 preguntas diferentes aspectos en relación a los criterios diagnósticos, pruebas complementarias, pautas de tratamiento y factores pronósticos en la sordera súbita, según los diferentes protocolos instaurados y experiencia de los participantes en la encuesta. Resultados: Participaron 293 otorrinolaringólogos españoles de forma anónima (14% del total). Respecto a criterios diagnósticos, destaca el requerimiento de confirmar una hipoacusia neurosensorial (91,1%), de inicio en menos de tres días (75%) y afectación de tres frecuencias consecutivas (76,4%). Más de la mitad de los participantes solicitan resonancia magnética de CAI/APC (68,7%), y el 88,2% utiliza contraste con gadolinio en esta prueba. El factor pronóstico que se consideró con mayor frecuencia en la encuesta fue la demora hasta inicio del tratamiento con un 84,8%. Respecto al tratamiento empleado en casos primarios, la gran mayoría de los encuestados (99,7%) coinciden en la administración de corticoides. La vía oral es la más utilizada (66%), seguida de la administración intravenosa (29,6%), e intratimpánica (1,4%). El 92% no han tenido complicaciones mayores con el tratamiento corticoide sistémico. La vía intratimpánica es empleada en un 70% como rescate en fracasos. Conclusiones: En España, existe actualmente una importante disparidad en el uso de los medios diagnósticos en la sordera súbita y un mayor acuerdo en el uso de corticoides como su tratamiento. Sería necesario implementar medidas que permitan un mejor abordaje, homogéneo y consensuado de esta patología (AU)

Introduction: The objective of our study was to identify the diagnostic and therapeutic approaches in the different ENT Departments of Spain with respect to sudden deafness. We wanted to establish a basis to help to create a new nation-wide consensus, unifying treatment, diagnostic and follow-up criteria for this disease. Methods: We carried out an anonymous Internet survey, addressing Spanish ENT doctors nation-wide (n = 2,029), gathering in 33 questions different aspects about diagnostic criteria, additional tests, treatment procedures and prognostic factors in sudden deafness, according to the different protocols and experience of the participants in the survey. Results: A total of 293 Spanish ENT doctors (14%) took part anonymously. In relation to diagnostic criteria, is the most noteworthy was the requisite of a confirmed neurosensorial loss (91.1%) followed by "initiated in less than three days" (75%) and 3 consecutive frequencies affected (76.4%). More than half of the participants requested an MRI of the IAC/CPA (68.7%) and 88.2% used gadolinium in this test. The prognostic factor most frequently considered was delay in commencement of treatment onset (84.8%). As far as treatment of primary cases, most of the responders agreed on the use of corticosteroids (99.7%).
