OBJECTIVE: Removing the posterior canal wall or canal wall down mastoidectomy (CWDM) for the management of cholesteatoma remains controversial. We advocate partial removal of the posterior canal wall for complete eradication, followed by canal wall defect reconstruction to restore the normal anatomy and avoid the complications of CWDM. MATERIALS AND METHODS: Sixty-four patients with cholesteatoma (71 ears) were included. This study was conducted between 2009 and 2012...

The goal of this work is to develop an innovative method that combines bioprinting and endoscopic imaging to repair tympanic membrane perforations (TMPs). TMPs are a serious health issue because they can lead to both conductive hearing loss and repeated otitis media. TMPs occur in 3 to 5% of cases after ear tube placement as well as in cases of acute otitis media (the second most common infection in pediatrics), chronic otitis media with or without cholesteatoma, or as a result of barotrauma to the ear. About 55,000 tympanoplasties, the surgery performed to reconstruct TMPs, are performed every year and the commonly used cartilage grafting technique has a success rate between 43% to 100%...

OBJECTIVE: We aimed to analyze preoperative and intraoperative clinical characteristics of chronic perforated otitis media by patient age. MATERIALS AND METHODS: We analyzed 137 tympanoplasties for chronic perforated otitis media in 133 patients. Exclusion criteria were ear adhesions, cholesteatoma, and a history of tympanoplasty. Patients were divided into a younger group (aged 15-39 years), a middle group (40-64 years), and an elderly group (≥65 years). We compared tympanoplasty technique (using Wullstein classification), mastoid air-cell area measured by temporal bone computed tomography, preoperative aeration of the temporal bone, mean preoperative hearing (at 500 Hz, 1000 Hz, and 2000 Hz), and patch effect calculated by the pre- and post-patch air-bone gap at frequencies of 250 Hz and 500 Hz among the three age groups...

PURPOSE: There are no formal radiologic criteria to stratify patients for transcanal (TEES) or transmastoid endoscopic ear surgery for resection of cholesteatoma. We aim to determine 1) whether standard preoperative computed tomography (CT) findings are associated with the need for conversion to a transmastoid approach and 2) the amount of time added for conversion from TEES to transmastoid techniques. MATERIALS AND METHODS: Retrospective chart review of consecutive pediatric and adult cases of TEES for primary cholesteatoma from 2013 through 2015 (n=52)...

OBJECTIVES: Mechanotransduction plays an important role in cell-proliferative activities. Negative pressure in the middle ear is thought to be an important factor related to the etiology of acquired middle ear cholesteatoma. However, the correlation between negative pressure in the middle ear and the mechanism of middle ear cholesteatoma formation remains unclear. In this study, we investigated the expression of key molecules for mechanotransduction immunohistochemically. METHODS: An immunohistochemical analysis was performed using anti-Wnt5a (a marker of alternative Wnt signaling), -Yes-associated protein (YAP) (a marker of mechanosensing) and -pYAP (phosphorylated YAP at Ser 127: inactivated YAP) antibody in the tympanic membrane (TM) under a negative pressure load and in human middle ear cholesteatoma tissues...

Cochlear fistula in the chronic otitis media (COM) without cholesteatoma is an extremely rare with only a few cases reported in the literature to this date. We describe a case of cochlear fistula observed in a female with COM without cholesteatoma. This report presents the first clinical case of a transtympanic iatrogenic trauma by habitual cotton swabs probably causing cochlear fistula.

OBJECTIVES: To describe a multicenter study regarding surgical management of bilateral congenital cholesteatoma (BCC) and underline the importance of endoscopes in the management of this condition. In BCC, hearing preservation is more crucial than in unilateral cases. The endoscopic approach allows complete removal of cholesteatoma via a minimally invasive technique offering low residual disease rates while preserving the normal physiology of the middle ear and possibly the ossicular chain...

The congenital cholesteatoma is a rare benign tumor whose diagnosis is mainly made during childhood. Otoscopic examination shows a white retrotympanic collection with or without hearing loss. In case of a late diagnosis, the disease will spread to the surrounding structures, leading to ossicules destruction, facial palsy, sensorineural hearing loss and vestibular dysfunction. Surgery is the therapeutic gold-standard, with different techniques chosen based on the cholesteatoma's extension. Patient should benefit from a long term medical and radiological (MRI) follow-up...
