Comparative analysis of moderate and severe tympanic membrane retractions in children and adults.

Objective: Owing to the limited literature demonstrating the correlation between the degree of severity of retractions and the degree of hearing loss in children and adults, the study aimed to compare the differences in the location, the severity, and the air-bone gap (ABG) of tympanic membrane (TM) retractions in children and adults.

Methods: Cross-sectional study, in a tertiary hospital. Consecutive patients with moderate or severe TM retractions (661 ears) between August 2000 and January 2019 were evaluated.

Sensorineural Hearing Loss in Cholesteatoma.

Objective: To determine whether middle ear cholesteatoma is associated with, sensorineural hearing loss, and whether patient age, cholesteatoma growth pattern, or, air bone gap size contribute to inner ear impairment.

Study Design: Cross-sectional comparative.

Setting: A tertiary hospital.

Classification of Cholesteatoma According to Growth Patterns.

Importance: Several classifications of cholesteatoma exist, but there are controversies about their clinical application.

Objective: To classify cholesteatomas and describe the prevalence of the subtypes.

Design, Setting, And Participants: A cross-sectional comparative study of 414 ears in 356 consecutive patients with middle ear cholesteatoma and no history of ear surgery treated at a tertiary hospital was conducted from March 8, 2000, to March 30, 2015.

Hystology findings' correlation between the ossicular chain in the transoperative and cholesteatomas.

Unlabelled: Chronic otitis media is hystopathologycaly defined as the presence of irreversible inflammatory tissue changes in the middle ear. Ossicular lesions represent the most prevalent change.

Aim: to correlate the degree of ossicular chain changes seen during surgery with the inflammatory histological degree and the thickness of the cholesteatoma perimatrix.
