Endoscopic-Assisted Canal Wall-up Tympanomastoidectomy for Reduction of Residual Cholesteatoma.

 The treatment of cholesteatoma is generally surgical, and the major obstacle is the high prevalence of recidivism. The endoscopic ear surgery technique is proposed to minimize this problem.  To utilize endoscopes to visualize and manipulate cholesteatoma residues after microscopic removal  Cross-sectional study.

Tympanic membrane perforations: a critical analysis of 1003 ears and proposal of a new classification based on pathogenesis.

Purpose: To present a large series ears with tympanic membrane perforations (TMP), to describe their characteristics, and to propose a new classification system based on the pathogenesis of TMP.

Methods: This cross-sectional study was conducted at a tertiary university hospital with 1003 ears (792 consecutive patients with TMP in at least 1 ear). Otoendoscopy and audiometry were performed.

Central versus marginal tympanic membrane perforations: does it matter? An analysis of 792 patients.

Background: There is a lack of studies concerning chronic otitis media without cholesteatoma.

Objectives: To perform an analysis of tympanic membrane perforations (TMP), compare the parameters of central and marginal TMP, combining both the traditional and more recent technologies available.

Material And Methods: 792 consecutive patients.

Characteristics of 419 patients with acquired middle ear cholesteatoma.

Introduction: Cholesteatoma is a destructive lesion that can result in life-threatening complications. Typically, it presents with hypoacusis and continuous otorrhea as symptoms. Because it is a rare disease, there are few studies in Brazil describing the characteristics of patients with the disease.
