Öğe Intraosseous lipoma presenting as a sphenoid sinus mass(Verduci Publisher, 2011) Dogan, M.; Kahraman, A. S.; Firat, C.; Kahraman, B.; Karatas, E.; Kizilay, A.Intraosseous lipoma is an uncommon mesenchymal tumor that is frequently found in appendecular skeleton. In extremely rare conditions, it can appear in sphenoid bone, and only 2 cases have been described in literature until now. We present a case of lipoma in the body of the sphenoid bone mimicking sphenoid sinus tumor. A 16-year-old man presented to Department of Otorhinolaryngology with a complaint of nonspecific headache. There were any clinical findings on physical examination. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed and the diagnosis was made on these imaging findings. Other diagnostic technique, invasive histopathological assessment was not necessary. To our knowledge, this is the first case of lipoma in the body of the sphenoid bone with indentation to sphenoid sinus. The patient has been followed-up radiologically without the need for surgery for two years.Öğe Olfactory disfunction and its relation olfactor bulbus volume in Parkinson's disease(Verduci Publisher, 2014) Altinayar, S.; Oner, S.; Can, S.; Kizilay, A.; Kamisli, S.; Sarac, K.OBJECTIVE: Olfactory dysfunction is the most frequently seen non-motor symptom of Idiopathic Parkinson's disease (IPD). The aim of this study is to analyze selective olfactory dysfunction, and olfactory bulb volume (OBV) in subtypes of IPD, and compare them with those of the healthy controls. PATIENTS AND METHODS: Our study included 41 patients with IPD and age and gender matched 19 healthy controls. IPD patients were either tremor dominant (65.9%; TDPD) or non-tremor dominant (34.1%; NTDPD) type. All patients underwent neurological, ear, nose, and throat examinations, and orthonasal olfaction testing. Magnetic resonance imaging (MRI) technique was used to measure the volume of the olfactory bulb. RESULTS: A significant decrease in olfactory identification scores was found in the patient group. The patients had difficulty in discriminating between odors of mothballs, chocolate, Turkish coffee and soap. OBV did not differ between the patient, and the control groups. In the TDPD group, odor identification ability was decreased when compared to the control group. However, odor test results of NTDPD, control and TDPD groups were similar. OBV estimates of the TDPD group were not different from those of the control group, while in the NTDPD group OBVs were found to be decreased. In all patients with Parkinson's disease OBV values did not vary with age of the patients, duration of the disease, age at onset of the disease, and Unified Parkinson's Disease Rating Scale motor scores (UPDRS-m). CONCLUSIONS: Olfactory function is a complex process involving olfactory, and cortical structures as well. In Idiopathic Parkinson's disease, changes in OBV do not seem to be directly related to olfactory dysfunction.Öğe A rare pathology that cause of hearing loss and deafness: Nasopharyngolaryngeal amyloidosis(Galenos Yayincilik, 2012) Toplu, Y.; Bentli, R.; Can, S.; Samdanci, E.; Kizilay, A.Amyloidosis is a disease that characterized by deposition of an abnormal fibrillary protein in the extracellular area of various tissues and organs. It is more commonly seen in males and in the over 40 age period. Even though immunologic factors are under an immense suspicion, its etiology is still unknown. Amyloidosis is observed in 3 groups as primary systemic amyloidosis, secondary systemic amyloidosis and localized amyloidosis according to its prevalence. Amyloidosis is demonstrated in systemic form generally, but it may be found as localized form in some organs very rarely. Larynx is the most common involved site of localized amyloidosis. In this paper we described very rare form of localized amyloidosis; rhinonasopharingolaryngeal amyloidosis that hasn't been defined in our country previously.
