“…El vértigo es la complicación postquirúrgica más frecuentemente encontrada según los estudios actuales llegando a ser hasta 37% inclusive más alto según las series de casos, aunque resuelve en la mayoría de los pacientes en el seguimiento clínico (20). En lo evaluado de la muestra, la mayoría de pacientes con otosclerosis intervenidos fueron de sexo femenino con un 56.1% y la edad promedio fue de 46.6 años, mayores de 40 años fue el grupo etario de mayor afectación con un 53.7%, de manera similar Adedeji y colaboradores reportaron un predominio de sexo femenino en los pacientes tratados en un 56.6% y una edad promedio de 42.02 ± 12.8 años con mayor afectación entre el grupo etario de 30 a 45 años con un 44.4% (21). Bartel describe en los estudios incluidos en su metaanálisis que el 62% de la población fue de sexo femenino de los 1531 pacientes estudiados (22).…”

“…De manera distinta Singh y Goyal en su serie de casos describe una afectación de predominio masculino en un 65% y una edad promedio de afectación de 29.1 años (23). Respecto a la lateralidad de afectación el 58.5% de nuestro estudio comprometió el oído derecho, por su parte Adedeji evidencia una distribución ecuánime del 50% entre ambos oídos (21). De manera similar el 53.3% de los pacientes descritos por Khorsandi tuvieron afectado el oído izquierdo (24).…”

Introducción: La otosclerosis manejada quirúrgicamente con estapedotomia ha mostrado mejora del umbral auditivo mediante un abordaje trascanal o retroauricular. Objetivo: Caracterizar la respuesta al tratamiento quirúrgico con estapedotomia trascanal y retroauricular en pacientes con diagnóstico de otosclerosis en un centro universitario. Diseño: Estudio observacional descriptivo retrospectivo tipo serie de casos. Metodología: Se incluyeron pacientes con diagnósticos de otosclerosis atendidos en el Hospital Universitario Clínica San Rafael quienes cumplieron criterios de elegibilidad entre el año 2014 a 2020. Resultados: Se incluyeron 33 pacientes intervenidos con abordaje trascanal y 8 con abordaje retroauricular, la edad promedio fue de 46.6 años. La mayoría pacientes de sexo femenino (56.1%). Se evidenció mejora del umbral auditivo en el 89.9% del total de la muestra. La presencia de variantes anatómicas se describió en un 26.8%, la variante más común fue el prolapso del nervio cuerda del tímpano (14.5%). La complicación intraoperatoria más común fue la sección del nervio cuerda del tímpano (9.8%). La presencia de complicaciones y variantes anatómicas fue más prevalente con abordaje retroauricular. Conclusiones: La estapedotomia con abordaje retroauricular y trascanal mostro mejora del umbral auditivo equiparable a la literatura mundial, la presencia de variantes anatómicas se correlaciono con complicaciones postoperatorias.

“…Otosclerosis is more common in Caucasians and Asians than in Africans. Though definite etiology of otosclerosis is still not identified, some factors associated with it such as pregnancy and measles virus, have been reported in various literatures 5 . The period of onset is mainly between 20 to 45 years of age, with a higher prevalence in women than in men.…”

Background: Otosclerosis is one of the commonest diseases of the ear mostly involves the otic capsule. Most often otosclerotic foci appear in stapes region leading to stapes fixation, predominantly affect the adolescence female. The most common presenting symptom of clinical otosclerosis is conductive deafness. The mainstay of treatment for otosclerosis is surgery. Surgical options include stapedectomy, stapedotomy with or without stapedial tendon preservation. The latter being is the procedure of choice. Aim: The aim of this study is to compare the outcome of uncomfortable loudness level in stapedotomy with or without stapedial tendon preservation. Methods: A prospective observational study was conducted in the Department of Otolaryngology-Head & Neck Surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka for 18 months in patients with otosclerosis. Total 30 subjects were selected based on the inclusion and exclusion criteria. All patients were assessed pre-operatively by clinical examination, otoscopy and microscopic examination. Hearing was assessed by pure tone audiometry. Uncomfortable level and stapedial reflex threshold were tested in all cases. The selected cases were placed into two groups. Stapedial tendon resection in Group-I and stapedial tendon preservation in Group-II. Post-operative follow up was done at 3 months and 6 months. Hearing and uncomfortable loudness level were evaluated with PTA during follow up by calculating the average of 500Hz, 1000Hz, 2000Hz and 4000HZ. The data were calculated manually. The statistical significance was set to P< 0.05. Results of the study were expressed as mean, standard deviation (± SD), frequency and percentages. Means and standard deviations were reported for continuous variables. Frequencies and percentages were reported for categorical variables. Unpaired Student’s t test was done to compare the continuous variables and Chi Square test was done to compare the categorical variables. Results: In this study preoperative average ABG for group I and group II were 35 ± 4.57 dB and 34 ± 4.17 dB respectively. In group I, post operative average ABG after 3 months and 6 months were 14 ± 3.7 dB and 13±3.3 dB respectively. Post operative average ABG after 3 months was 13 ± 5.7 dB and was 12 ± 4.4 dB for group II. But the hearing improvement between two groups was not statistically significant. In case of preoperative mean UCL was 95 ± 1.8 dB and 96 ± 2.5 dB for group I and group II respectively. Postoperative mean UCL after 3 months was 96 ± 3.57 dB and after 6 months was 99 ± 6.28 dB in group I. For group II, postoperative mean UCL after 3 months and 6 months was 107±4.2 dB and 113 ± 3.2 dB respectively. Here mean UCL was on average 11 dB higher for group II in 3 months and additional 6 dB improvement noted after 6 months, but show minimal change in group I. This finding was statistically significant. Conclusion: Preservation of the stapedial tendon is the choice in the surgical treatment of otosclerosis which helps to improve functional outcomes as well as to provide the more physiologic protection of middle ear. Postoperative discomfort threshold levels were increased in patients who had their stapedial tendon restored. Bangladesh J Otorhinolaryngol 2021; 27(2): 117-123

“…5,6 It can occur in both ears about 80% of patients. 7 It most commonly involves the cochlear wall anterior to the oval window, followed by the round window niche and the cochlear apex. 8 The definite diagnosis can only be made preoperatively by observing the mechanical fixation of the stapes.…”

Classical and reversal stapedotomy both are exclusively done in otosclerosis but definite information regarding surgical advances, postoperative results, complications and information about how and in which patients these surgical techniques should exclusively be used are a source of continuous discussions. This prospective observational study was conducted in the Department of Otolaryngology-Head & Neck Surgery, Bangabandhu Sheikh Mujib Medical University, Shahbagh, Dhaka from July 2019 to December 2020 o compare the outcomes of classical and reversal stapedotomy in patients with otosclerosis. Total 28 cases of otosclerosis who underwent stapedotomy were divided in to two groups i.e. Group A (classical stapedotomy) & Group B (reversal stapedotomy) with 14 patients in each group. All patients were followed up post-operatively up to 3 months with Pure-tone audiometry (PTA). There is no significant difference between classical and reversal stapedotomy approach in terms of hearing improvement and complications. Chorda tympani injury was the main complication in both the groups. Regarding hearing gain and complications there was no significant difference between classical and reversal stapedotomy approach.
