BACKGROUND It is now common for parents to measure tympanic temperatures in children. The objective of this study was to assess the diagnostic accuracy of these measurements. METHODS Parents and then nurses measured the temperature of 60 children with a tympanic thermometer designed for home use (home thermometer). The reference standard was a temperature measured by a nurse with a model of t...

The radiographic appearance of the petrotympanic fissure, through whic h the chorda tympani nerve exits the tympanic cavity, is familiar to radiologists as a normal struc ture, not to be mistaken for a frac ture of the anterior wall of the external auditory canal [1, 2). However, th e rad iographic demonstration of the canaliculus chordae tympan i, the bony canal which transmits the chorda tymp...

A 40-year-old woman was referred by her primary care physician for evaluation after a routine physical exam revealed bilateral brownish pigmentation of the tympanic membrane. Head and neck examination in the otolaryngology clinic revealed bluish hue of both sclera, teeth, and portions of her pinnae. A hearing test revealed bilateral mild sensorineural hearing loss. The patient had a history of ...

OBJECTIVE To evaluate the therapeutic effects in terms of disease clearance and hearing improvement of canal wall up mastoidectomy in combination with Type I tympanoplasty in otitis media. METHODS A total of 78 patients (81 ears) with otitis media were treated by canal wall up mastoidectomy in combination with Type I tympanoplasty. The postoperative tympanic membrane morphology, average of pu...

We investigated the feasibility of using laser tissue welding techniques to perform transcanal underlay tympanoplasty. We used 10 temporal bones obtained from human cadavers. After creating a subtotal tympanic membrane perforation, we introduced harvested periosteum through the perforation and used laser tissue welding to secure the periosteum graft in place in an underlay fashion. The procedur...

UNLABELLED The knowledge of the relations between the noble and vital structures of temporal bone is still a great challenge for the otologic surgeon. The microscopic anatomic studies of the temporal bone are one of the greatest help to prevent lesions during surgical intervention. AIM To study the anatomic correlations between the carotid canal and the cochlea, and the occurrence of dehiscen...

A new method recently used for measuring the temperature is using tympanic thermometer. The aim of this study was to compare the accuracy of this method with rectal and axillary measurement in children less than 6 years old. A total of 220 pair ears, axillaries, and rectal sites were used to determine the body temperature in patients aged between 3 months to 6 years who referred to Emergency De...

Introduction: Hearing loss is fairly a common disorder which is usually treated with corticosteroids via systemic administration and/or intra-tympanic injection. This study aimed to compare the effectiveness of intra-tympanic injections of dexamethasone with its combination with hyaluronic acid in patients with sudden sensorineural hearing loss.   Materials and Methods: In this clinical trial, ...

Paragangliomas originate from glomus bodies which are non-working temporal bone chemoreceptors, derived from neuroectodermal cells of the neural crest. Tympanic paragangliomas have pulsatile tinnitus as its most frequent symptom, followed by conductive hearing loss, otalgia and ear fullness. Some patients may present vertigo and otorhagia. Our goal is to present two cases of tympanic paragangli...
