Introduction and objective: Tympanic Membrane Cholesteatoma (TMC) is a rare pathology of unknown etiology which occurs more frequently in pediatric population, being the presentation adults exceptional. Resection lesion usually surgical treatment through transcanal approach.

OBJECTIVES To evaluate the impact of lying on the ear on the measurement of body temperature by a tympanic thermometer. METHODS Participants in the study were healthy young people of the Nursing Department of the College of Health, Izmir, Turkey. Sixty-eight participants who agreed to participate, and who had no discharge or infection of the ear and no upper respiratory tract infection, were ...

A 6-year-old girl with Down syndrome was referred to our team for joint management. She was having severe speech and language difficulties. Her hearing was assessed, and the pure tone audiometry showed a moderate conductive hearing loss (40 dB) in the left ear and profound hearing loss in the right ear. A CT scan and MRI of temporal bone (Figs. 1 and 2) revealed a hypodense mass in the left tym...

Tinnitus is a common auditory phenomenon associated with many otological diseases, and is usually subjective. Objective tinnitus can be generated by para-auditory structures, usually derived from vascular or myogenic sources, or the eustachian tube. We present a rare case of intermittent unilateral tinnitus associated with eye blinking. Otoendoscopic examination showed that the external auditor...

OBJECTIVE To explain a clinical observation: a notch in the stimulus spectrum during transient evoked otoacoustic emission measurement in ears with secretory otitis media. METHODS The effects of tympanic under-pressure were investigated using a pressure chamber. A model of the ear canal was also studied. RESULTS Tympanic membrane reflectance increased as a consequence of increased stiffness...

In order to elucidate the pathophysiology of an undetermined conductive deafness without perforation of the tympanic membrane, comparative study was made in several factor with conductive deafness which has normal tympanic membrane and may be due to inflammation. Differences and similarities in the manner of ossicular damage were discussed in these conductive deafness. The morbidity rate of con...

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...

OBJECTIVES Tympanic membrane perforations are common, but there have been few studies of the factors determining the extent of the resulting conductive hearing loss. The aims of this study were to determine whether the size of tympanic membrane perforation, pneumatization of middle ear & mastoid cavity, and location of perforation were correlated with air-bone gap (ABG) of patients. METHODS F...

Objective: To investigate the expression of receptor for advanced glycation endproducts (RAGE) in adenoid hypertrophy in children and the change in the level of soluble receptor for advanced glycation endproducts (sRAGE) in tympanic effusion. Methods: Fifteen adenoidal specimens were collected from patients with adenoidal hypertrophy and secretory otitis media and patients with simple adenoidal...
