Mastoid obliteration and canal wall reconstruction with posterior auricular artery (PAA) fascia-periosteum flap.

OBJECTIVE: Unstable cavities are defined as cavities with cerumen accumulation that need frequent cavity cleaning in the out-patient clinic, cavities that are intolerant to water due to risk of infection or that are subject to frequent infection and otorrhoea. The objective of this study is to address the problem of troublesome mastoid cavities, with the performance of secondary mastoid obliteration and canal wall reconstruction, using a novel posterior auricular artery (PAA) fascia-periosteum flap. MATERIALS AND METHODS: A prospective study was designed, only secondary obliterations were included. Unstable mastoid cavities were defined as Merchant grade 2 or 3 and were included for surgery. RESULTS: At 12 months of follow up, a complete external auditory canal (EAC) and a self-cleaning ear were achieved in all 23 patients. Completely dry ears were achieved in 21 patients (91.3%). An air-bone gap improvement of 5dB was achieved. CONCLUSION: Mastoid obliteration and EAC reconstruction are effective procedures to treat troublesome post canal wall down mastoid cavities. They improve quality of life and enable patients to overcome ear discharge. A standard EAC size enables the utilization of conventional hearing aids, it also reduces the need for constant mastoid cleaning and decreases healthcare expenses. The PAA flap seems to be an effective procedure to achieve all these features, as it is used to obliterate the mastoid and becomes a structural component of the neo-EAC.

Transcanal endoscopic type 3 tympanoplasty with mastoid preservation for advanced active chronic mucosal otitis media.

BACKGROUND: Chronic mucosal otitis media is a very common ear disease for which patients attend otolaryngology clinics. Most of these patients present with actively discharging ears. AIMS/OBJECTIVES: This study aims to observe the middle ear space pathology and obtain surgical outcomes as a treatment for patients with advanced chronic mucosal otitis media with a transcanal endoscopic ear surgery approach. MATERIALS AND METHODS: A prospective study was designed, and patients suffering from chronic mucosal otitis media in the active suppurative phase with an air-bone gap larger than 20 dB were included. RESULTS: 70 operated ears were included. Underlying macroscopic pathology within the middle ear space was observed: Middle ear granulomas at 58.6%; Tympanosclerosis 41.4%. Blockage of the tympanic isthmus was evaluated, obtaining a blockage rate of 81.4%. At 12 months of evaluation after surgery, a postoperative ABG < 20 dB was achieved in 85.7% of the operated ears. An overall closed tympanic membrane was obtained in 88.6% of the patients. CONCLUSION: This prospective cohort study shows the short-term efficacy of transcanal endoscopic type 3 tympanoplasty with mastoid preservation for managing advanced chronic mucosal otitis media. Clinical trials are required to give more evidence to the present matter.

Objetivo: Las cavidades inestables se definen como cavidades que presentan acumulación de cerumen que requieren limpieza en la consulta de manera frecuente, son cavidades intolerantes al agua por su elevado riesgo de infección o tienen frecuentes infecciones y otorrea. El objetivo de este estudio es abordar el problema de las cavidades mastoideas problemáticas con una obliteración mastoidea secundaria y reconstrucción del conducto auditivo externo (CAE) usando un colgajo fascio-perióstico de la arteria auricular posterior.Materiales y métodosSe diseñó y realizó un estudio prospectivo, solo se incluyeron obliteraciones secundarias. Las mastoides inestables fueron definidas según la clasificación de Merchant como grado 2 o 3 y fueron incluidas para la cirugía.ResultadosA los 12 meses de seguimiento, se consiguió un CAE completo y autolimpiable en los 23 pacientes. Se lograron oídos completamente secos en 21 casos (91,3%). Se obtuvo una mejoría media en la brecha aire-hueso de 5dB.ConclusiónLa obliteración mastoidea y la reconstrucción del CAE son procedimientos eficaces para tratar mastoides problemáticas posmastoidectomías abiertas. Mejoran la calidad de vida de los pacientes y son efectivas para solventar la otorrea recurrente. La obtención de un CAE de tamaño estándar es importante para permitir que el paciente pueda utilizar una audioprótesis estándar, además de reducir la necesidad de limpieza de la cavidad de manera constante y la dependencia del paciente a los controles en la consulta, disminuyendo así el gasto en sanidad. El colgajo de arteria auricular posterior parece ser una herramienta útil para lograr todas estas características, y también es usado para obliterar las mastoides y se convierte en un componente estructural del neo-CAE.

Laser vs drill for footplate fenestration during stapedotomy: a systematic review and meta-analysis of hearing results.

OBJECTIVE: Stapes surgery is the gold standard surgical treatment nowadays for otosclerosis. Several controversies on the procedure have been reported; surgical techniques for most favorable outcomes are still on discussion. The objective of this study is to present an update of evidence-based medicine concerning the utilization of lasers and drilling for footplate fenestration during stapedotomy surgery. A systematic review and meta-analysis were conducted. MATERIALS AND METHODS: Publications in English in the last 5 years were searched in the PubMed/MEDLINE database and were systematically reviewed. A total of three articles were included according to the inclusion criteria, obtaining a total of 1531 patients managed surgically for otosclerosis, using laser or drill for footplate fenestration. Data were systematically extracted and hearing results were compared in a meta-analysis. RESULTS: For the drill group, a total of 978 patients were retrieved and data were obtained as follows: mean age was 50 years old; the female proportion was 62%; mean preoperative air-bone gap (ABG) of 28 dB; mean postoperative ABG of 8 dB; mean ABG improvement of 20 dB; an ABG closure rate to < 10 dB of 74%. For the laser group, a total of 553 patients were retrieved, data were obtained as follows: mean age was 47 years old; the female proportion was 63%; preoperative ABG of 26 dB; postoperative ABG of 8 dB; mean ABG improvement of 18 dB; an ABG closure rate to < 10 dB of 72%. CONCLUSION: The results from this study reveal that in regard to postoperative hearing results, surgical outcomes are comparable, and there is no statistically significant difference between the utilization of drills and lasers as a surgical instrument for the fenestration of the stapes footplate during stapedotomy surgery.
