Background: Cholesteatoma is a collection of keratinized squamous epithelium in middle ear and pneumatic areas temporal bone. It can be said as an invasive disease which often associated with sensorineural hearing loss. seen that loss varies the location disease, duration extension cholesteatoma. Aims Objectives: The aim this study to see association cholesteatoma bone conduction threshold diff...

OBJECTIVE To assess the reliability of high-resolution computed tomographic scan (HRCT scan) for the diagnosis of otosclerosis and to determine its usefulness to predict hearing deterioration and surgical difficulties. STUDY DESIGN Prospective study. SETTING Tertiary reference center. PATIENTS Two hundred nine ears (200 patients) presenting progressive conductive hearing loss with normal ...

This study was aimed to sequentially document the patient's audiological improvement after stapedotomy as measured by pure tone audiometry. This prospective clinical study was performed in a total of 112 patients (age range: 20 63 years), diagnosed with Otosclerosis who underwent Stapedotomy at the Department of Otology, Madras ENT Research Foundation, Chennai between September 2010 to March 20...

Bone Anchored Hearing Aids (BAHA). The bone anchored hearing aid or BAHA is a small vibrator that can be reversibly plugged onto a titanium screw that is implanted behind the ear. It transduces sound into vibration of the screw and stimulates the cochleae by means of the bone conduction pathway. The main indications are conductive hearing loss or mixed hearing loss with a moderate perceptive co...

BACKGROUND No studies have examined the association between cumulative low-level lead exposure and the prospective development of electrocardiographic conduction abnormalities, which may mediate the association between lead and several cardiovascular end points. OBJECTIVE We prospectively examined the association between lead exposure and the development of electrocardiographic conduction abn...
