A formal description of middle ear pressure-regulation

On Pressure Regulation of the Middle Ear

High-resolution gas volume change measurements bring new insights in pressure regulation of the middle ear.

Effect of laryngoscopy on middle ear pressure during anaesthesia induction.

AIMS The procedure of laryngoscopic orotracheal intubation (LOTI) has many impacts on several parts of the body. But its effect on middle ear pressure (MEP) is not known well. The purpose of this study is to evaluate the MEP changes subsequent to insertion of endotracheal tube with laryngoscope. SUBJECTS AND METHODS 44 patients were included in this study with a normal physical examination of...

Influence of continuous negative pressure in the rat middle ear.

OBJECTIVES/HYPOTHESIS High negative pressure in the middle ear was thought to be closely related to the etiology of retraction-type cholesteatoma. Recently, it has been detected that mechanical forces are important factors in epithelial turnover and affect cytoskeletal remodeling. Continuous negative pressure in the middle ear may possibly accelerate the proliferation and differentiation of epi...

Middle Ear Salivary Gland Choristoma: A Case Report

Salivary gland choristoma of the middle ear cavity is a very rare condition. These lesions are a result of a defective embryonic development and their adjacent structures may be associated with abnormalities. Here we report a case of salivary gland choristoma of the middle ear who presented to Be’sat Hospital, Tehran, Iran in 2015 with unilateral conductive hearing loss. There are 41 case repor...
