Ossicular repositioning and ossicular prostheses are said to offer an oppotunity to preserve the air space of the middle ear and improve the transmission of sound to the stape footplate. Depending upon the pathological circumstances, any convenient remaining portion of the auditory ossicles may be used to reconstruct a functioning ossicular chain. But the problem of reconstruction is not simple...

OBJECTIVES/HYPOTHESIS To prospectively evaluate surgical findings and hearing results in children undergoing surgery for congenital malformations of the ossicular chain with a mobile stapes footplate (Teunissen and Cremers class III malformations). STUDY DESIGN A nonrandomized, nonblinded, prospective case series. METHODS Fifteen consecutive pediatric patients who underwent 17 surgical proc...

This article describes a new surgical method for total ossicular reconstruction in a case of a broken stapes footplate. We developed the technique of the "cartilage shoe sandwich," which consists of two surgical steps. First, the closure of the oval window is achieved by a cartilage shoe without a central perforation. During this surgical intervention, the prearrangement of a secure placement o...

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. STUDY DESIGN Cross-sectional ...

Background: Exploratorytympanotomy is done to identify the cause ofconductivehearingloss in a patient withintacttympanic membrane. Objective: Toenlist and analyze the middle ear pathologies in patients with conductive hearing loss with intact tympanic membrane. Methods: 50 patients in age group between 20 years and 50 years, with hard of hearing, consulting department of ENT at a tertiary care ...

A sweep-frequency tympanometer has been developed to diagnose auditory ossicular lesions more precisely. This device measures acoustic middle ear features by changing the probe tone frequency continuously. The oscillator sweeps frequency of the probe tone from 200 to 2,500Hz 1.5 seconds. A microphone picks up the changes in the acoustic pressure and the phase in the external auditory meatus dur...

Objectives: To evaluate the anatomical and audiological out­ comes of synchronous ossiculoplasty with ossicular replace­ ment prosthesis during canal wall down mastoidectomy for advanced cholesteatoma. Methods: The prospective study was done at a tertiary referral institute included 30 patients of cholesteatoma who underwent canal wall down mastoidectomy. Ossicular reconstruction was performed ...

Background: Conductive hearing loss due to ossicular abnormalities occurs from many causes, including trauma, infection, cholesteatoma, surgery and congenital anomalies. Surgical reconstruction of the ossicular chain is a wellestablished procedure for repair of ossicular defects, but is still plagued by high failure rates. Underlying disease and proper sizing of prostheses are two challenges th...

Objective The purpose of this study is to evaluate our experience with endoscopic repair of ossicular discontinuity at the incudostapedial joint, with or without an intact stapes suprastructure, and present our hearing results. We classify results based on the causative pathology, the type of ossiculoplasty, and type of lesion. We demonstrate the ability to endoscopically place a total ossicula...
