ABSTRACT
INTRODUCTION: Otitis media, mastoiditis or the pressure effect of tumorous lesions such as cholesteatoma can be the cause of facial canal dehiscence and facial nerve paralysis. The most common segment involved in dehiscence is the tympanic segment and the second most common is the lateral aspect of the facial canal in the oval window area. OBJECTIVE: To determine the prevalence of the facial canal dehiscence and the relationship between the angle at the second genu of the facial nerve and facial canal dehiscence. METHODS: We evaluated the surgical findings in 113 patients who underwent surgery for cholesteatoma. Facial canal dehiscence was detected in 62 of the 113 patients. Patients were divided into two groups: Group 1, with dehiscence of the facial canal and Group 2, without dehiscence of the facial canal. RESULTS: The mean angles at the second genu of the facial nerve in Groups 1 and 2 were 117.8°±9.63° and 114°±9.9°, respectively. There was a statistically significant difference between the mean angles at the second genu for the two groups (p=0.04). CONCLUSION: In patients with dehiscence of the facial canal, the angle at the second genu was found to be wider than those without dehiscence.

The diagnosis of sphenoid sinus diseases is difficult due to nonspecific history and physical examination findings. Sphenoid sinus is a rare localization for aspergilloma. Delay in diagnosis and treatment can result in serious complications. Presently described is case of sphenoid sinus aspergilloma. Patient had been treated by department of psychiatry for many years due to sleep disturbances and headache. Clinical and radiological features of rare case of sphenoid sinus aspergilloma are discussed.

OBJECTIVES: Allergic rhinitis (AR) occurs when the symptoms of rhinitis arise as a result of allergen-induced nasal mucosal inflammation. In the presence of rhinitis symptoms without infection or an allergic reaction in the nose, non-allergic rhinitis (NAR) is considered. Adults with these diseases have increased frequency of olfactory dysfunction. The aim of the present study is to assess olfactory function in children with AR and NAR. METHODS: A total of 77 children (aged six to 18 years) with AR and NAR were included in the study. The control group consisted of 45 healthy children. Sniffin' Sticks test was applied to both groups. The association between odor scores and demographic, clinical, and laboratory results was investigated. RESULTS: Forty two patients had allergic rhinitis. No significant difference was observed between patients with rhinitis and healthy controls with respect to odor scores. No association was observed between odor scores and the severity of rhinitis and the laboratory results of the patient groups. Odor identification and total odor scores of the patients with rhinitis lasting for longer than three years were significantly lower than those in the patient group with rhinitis lasting for one to three years. In the AR and control groups, the odor scores were found to increase with age. CONCLUSIONS: When compared with healthy children, children with allergic rhinitis and non-allergic rhinitis were not found to have reduced olfactory function. The duration of rhinitis may be associated with the olfactory dysfunction in children with rhinitis.

Schwannoma is a benign neoplasm originating from schwann cells of the peripheral nerve sheath. Although nearly half of all schwannomas involve the head and neck region, nasal and paranasal sinus presentations are very rare in the literature. We present a case of nasal schwannoma originating from the right nasal cavity. A 59-year-old man presented with complaints of progressive right nasal obstruction and headache. Endoscopic examinations revealed a mass that filled the right middle meatus. At first glance, it was not like polyp tissue. Endoscopic sinus surgery was performed under general anesthesia, and the mass was completely removed.
