Techniques and biomaterials for reconstructive middle ear surgery are continuously and steadily developing. At the same time, clinical post-surgery results are evaluated to determine success or failure of the therapy. Routine quality assessment and assurance is of growing importance in the medical field, and therefore also in middle ear surgery. The exact definition and acquisition of outcome p...

Materials used in ossicular replacement prostheses must possess appropriate biological properties, such as biocompatibility, stability, no cytotoxicity. Due to the risk of infection (otitis media and chronic otitis media), it is desirable to use an antibacterial agent for illness prevention during the ossicular reconstruction. The goal of this work was to observe biological properties of a new ...

OBJECTIVES/HYPOTHESIS To evaluate the effectiveness of bone cement on mean postoperative air-bone gap (ABG) and the proportion of ABG closure to within 20 dB in patients undergoing ossicular chain reconstruction or revision stapes surgery. DATA SOURCES PubMed, Embase, and Central. METHODS A systematic search was conducted. Studies reporting original study data were included. Relevance and r...

OBJECTIVE To evaluate the long-term results and predictive factors of a good outcome with the use of a total ossicular replacement prosthesis in children. DESIGN Retrospective case review. SETTING Tertiary referral center. PATIENTS The study included 114 children (116 ears). INTERVENTIONS A total of 116 ears underwent total ossicular chain reconstruction with a titanium prosthesis. Cart...

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 ...

The aim of the study was to describe ossicle resorption in chronic otitis with cholesteatoma and correlate it with clinical parameters such as age, contralateral ear condition, tympanic membrane aspect, cholesteatoma pathogenesis and extension, associated lesions and hearing threshold. Preoperative clinical data were collected for 140 patients with chronic otitis with cholesteatoma, whose ossic...

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...
