OBJECTIVES/HYPOTHESIS High-resolution optical imaging is an imaging modality that allows visualization of structural changes in epithelial tissue in real time. Our prior studies using contrast-enhanced microendoscopy to image squamous cell carcinoma in the head and neck demonstrated that the contrast agent, proflavine, has high affinity for keratinized tissue. Thus, high-resolution microendosco...

The aim of this study was to determine middle ear pressure changes during the operation performed under anaesthesia induced by isoflurane or desflurane. This was a prospective, case-control study. A total of 38 children with no middle ear pathology scheduled for inguinal hernia surgery were included in the study. Group I (n = 22) received isoflurane and Group II (n = 16) received desflurane. Ba...

OBJECTIVE Comparing the endoscopic and microscopic approaches in stapes surgery, and establishing the surgical approach that allows better results in terms of visualization of the middle ear structures and aids assistant's training. MATERIALS AND METHODS Twenty-one residents from the first to the fifth year of training in Otolaryngology were enrolled in this prospective study. A questionnaire...

150 Abstract Chronic otitis media is the major reason for middle ear surgery. Epidemiological studies have revealed high heritability of persistent or recurrent middle ear inflammation. The genetic basis of chronic otitis media is complex, but a number of methods can be used to interrogate this complexity. The most promising method is the identification of genetic mutant mouse models, which may...

Accidental injury to the facial nerve where the bony canal defects are present may result with facial nerve dysfunction during otological surgery. Therefore, it is critical to know the incidence and the type of facial nerve dehiscences in the presence of normal development of the facial canal. The aim of this study is to review the site and the type of such bony defects in 144 patients operated...

Materials & Methods; The patient had experienced a head injury 26 years previously which resulted in recurrent episodes of meningitis. Previous surgeries, one neurosurgical operation and three middle ear operations were ineffective. The patient constantly complained about headaches, dizziness, balance disorder, hypoacusis in the right ear and visual dysfunction. During the middle ear surgery, i...
