Tympanic membrane perforation is a common problem leading to hearing loss. Despite the autoregenerative activity of the eardrum, chronic perforations require surgery using different materials, from autologous tissue - fascia, cartilage, fat or perichondrium - to paper patch. However, both, surgical procedures (myringoplasty or tympanoplasty) and the materials employed, have a number of limitati...

Correspondence First of all, we would like to thank you for your interesting comments to our study. Our study was concerning to the application of synthetic bio-material patch. As your recommendation, natural healing rate of acute tympanic membrane perforati...

In this research, anatomical descriptions of the structure of the temporal bone and auditory ossicles have been performed based on dissection of ten guinea pigs. The results showed that, in guinea pig temporal bone was similar to other animals and had three parts; squamous, tympanic and petrous .The tympanic part was much better developed and consisted of oval shaped tympanic bulla with many re...

There is marked diversity in the reported success rates for achieving an intact tympanic membrane following myringoplasty. Controversy exists about the factors thought to influence surgical outcome. Both of these facts have important implications for obtaining informed consent prior to surgery. This study reviews the factors thought to determine the likelihood of achieving complete closure of t...

Superglue in the ear as a foreign body is an uncommon presentation. We report the case of a lady who accidentally instilled superglue directly onto her tympanic membrane and presented five days later. We successfully removed the glue with acetone and managed to preserve the integrity of the tympanic membrane.

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 ...

OBJECTIVE The goal of this study was to evaluate the effects of perforation edge approximation and direct application of basic fibroblast growth factor (bFGF) each alone on the healing of large traumatic tympanic membrane perforations with inverted edges in humans. STUDY DESIGN Prospective, sequential allocation, three-armed, controlled clinical study. SETTING University-affiliated teaching...

Turtles, like other amphibious animals, face a trade-off between terrestrial and aquatic hearing. We used laser vibrometry and auditory brainstem responses to measure their sensitivity to vibration stimuli and to airborne versus underwater sound. Turtles are most sensitive to sound underwater, and their sensitivity depends on the large middle ear, which has a compliant tympanic disc attached to...
