The feasibility of virtual otoscopy (VO) imaging was evaluated in five dogs with experimentally induced otitis media, two control dogs, and two canine patients with otitis media. VO images of the tympanic cavity and ossicles were generated with commercially available software using raw computed tomography (CT) data. Eight out of 10 ears inoculated with pathogen exhibited obvious clinical signs ...

BACKGROUND Tympanic membrane perforations vary in size, shape and position. The degree of conductive deafness varies with the size and position of the tympanic membrane perforation. OBJECTIVE This study is to determine the pattern and causes of tympanic membrane perforation. METHOD Hospital based study at the ENT Clinic, UCH, Ibadan. Consecutive patients seen during the period of study with...

BACKGROUND AND OBJECTIVE Inaccurate measurements of body temperature following cardiopulmonary bypass may be associated with serious complications. The purpose of this study was to determine whether axillary and tympanic temperature measurements correlate with the urinary bladder temperature in the early postcardiac surgery period. METHODS Forty-nine adult patients who underwent cardiac surge...

The middle ear pressure variation is one of the most important factors that causes discomfort on flight passengers and crew. The purpose of this work is to develop a mathematical model of the middle ear cavity pressure variation during typical flight’s conditions. The middle ear cavity was modeled as a gas chamber that transfer gas to other physiological systems trough three different ways. One...

INTRODUCTION THE tympanic membrane of the adult frog is divisible into three histologically distinct parts, viz. an inner epithelial layer, continuous with the mucous membrane of the tympanic cavity, the former being closely applied to a thin lamina propria conforming in shape and area to that of the annular tympanic cartilage to which it is attached at its peripheral borders. The third and out...

Myringotomy and tympanostomy are related terms that are sometimes used interchangeably to describe an opening in the tympanic membrane. In this policy, the term myringotomy will be used to describe a temporary opening in the tympanic membrane without insertion of a pressure-equalizing tube (PET), while tympanostomy will be used to describe an opening in the tympanic membrane in conjunction with...

Otitis media diagnosis can be assisted by measuring the shape of the tympanic membrane. We have developed an ear speculum for an otoscope, including spatially distributed source and detector optical fibers, to generate source-detector intensity matrices (SDIMs), representing the curvature of surfaces. The surfaces measured were a model ear with a latex membrane and harvested temporal bones incl...

BACKGROUND Monitoring of body temperature is an important clinical procedure in the care of sick children, especially the under-5 children, as many disease conditions present with fever. The oral mercury-in-glass thermometer which has relatively good accuracy cannot be used in children less than 5 years because it requires their cooperation. OBJECTIVE This study was aimed at using the infrare...

OBJECTIVE To assess middle ear aeration after total mastoid obliteration using bone pate and hydroxyapatite performed at the second stage of intact-canal-wall (ICW) tympanoplasty. STUDY DESIGN Retrospective study. SETTING Tertiary referral hospital. PATIENTS Forty-two ears with cholesteatoma underwent the obliteration. Computed tomography (CT) scan 1 week before the second-stage operation...
