    Anterior burun tamponunun orta kulak basıncı üzerine etkisi
    (2003) Harputluoğlu, Uğur; Koçak, Salih; Öztürk, Özcan; Demirci, Levent; Egeli, Erol
    Amaç: Septoplasti ameliyatı yapılan hastalarda anterior burun tamponunun orta kulak basıncına etkisi araştırıldı. Hastalar ve Yöntemler: Çalışmaya burun tıkanıklığı nedeniyle septoplasti ameliyatı uygulanan 43 erişkin hasta (26 erkek, 17 kadın; ort. yaş 30; dağılım 18-56) alındı. Tüm hastalarda işitme kaybı olmamasına, otoskopik muayenenin normal olmasına ve ameliyat öncesi timpanogramın tip A olmasına dikkat edildi. Septoplasti ameliyatı sonrası klasik anterior burun tamponu uygulandı ve 36 saat kadar burunda tutuldu. Timpanometrik ölçümler ameliyat öncesinde, tamponun çıkarılmasından hemen önce ve ameliyat sonrasında beşinci günde yapıldı. Ameliyat öncesi ve sonrasında orta kulak basınçları arasında 50 daPa veya daha fazla farklılık olması anlamlı kabul edildi. Bulgular: Hiçbir hastada orta kulak efüzyonu gelişmedi. Ameliyat öncesi ve ameliyat sonrası birinci günkü orta kulak basınçları arasında anlamlı farklılık bulundu. (p<0.05) Ameliyat sonrası beşinci günkü kontrol timpanogramlarmda östaki disfonksiyonunun düzeldiği görüldü (p<0.05). Sonuç: Septoplasti ameliyatlarından sonra, cerrahi travma ve burun tamponunun etkisine bağlı olarak orta kulak basıncı düşmekte, bu durum tampon çıkarıldıktan sonra'normal sınırlara dönmektedir.

    Evaluation of the inferior turbinate in patients with deviated nasal septum by using computed tomography
    (Wiley, 2004) Egeli, Erol; Demirci, Levent; Yazıcı, Burhan; Harputluoğlu, Uğur
    Objectives/Hypothesis. The objective was to measure the dimensions, composition, and possible structural and radiological changes of the compensatory hypertrophic inferior turbinate in patients with deviated nasal septum. Study Design: A prospective, non-randomized clinical trial at a university medical center. Methods. Twenty-three patients with deviated nasal septum and compensatory hypertrophy of the inferior turbinate in the contralateral nasal cavity were examined by computed tomography. Results. The dimensions of the compensatory hypertrophic inferior turbinate in patients with septal deviation were compared with normal control subjects. The difference in width of the medial and lateral mucosa and the conchal. bone between the two groups was statistically significant (P <.05). Conclusion. The present study uncovers the dimensions and composition of the inferior turbinate with compensatory hypertrophy in patients with nasal septum deviation. The findings support the decision to excise the inferior turbinate bone at the time of septoplasty, because of the significant bony and mucosal expansion.

    Papillary carcinoma of the thyroglossal duct cyst in childhood
    (Springer-Verlag, 2003) Öztürk, Özcan; Demirci, Levent; Egeli, Erol; Çukur, Selma; Belenli, Olcay
    Thyroglossal duct carcinoma is a rare malignancy that is usually diagnosed postoperatively. Approximately 150 cases have been reported in the literature. Eighty-five percent of these were papillary carcinomas. Controversies exist concerning its nature and treatment. In this report, we present an 11-year-old boy with an anterior cervical cystic mass originating in the thyroglossal duct. After a primary Sistrunk procedure, the cyst and tract extending to the foramen caecum at the base of the tongue in continuity with the midportion of the hyoid bone were resected. Histopathologic study demonstrated a papillary carcinoma. After 4 months of follow-up, the patient is asymptomatic without any evidence of recurrence. The clinical and histopathological features and therapeutic options are discussed.

    Syndromic etiology in children at schools for the deaf in Turkey
    (Elsevier Sci Ireland Ltd, 2004) Sılan, Fatma; Demirci, Levent; Egeli, Ayten; Egeli, Erol; Önder, Halil İbrahim; Öztürk, Özcan; Ünal, Zehra Seda
    Objective: The aim of this study was to determine the syndromic etiology of bilateral severe sensorineural hearing disorders in children and current etiological causes to reduce the cases in the unknown group. Methods: This study was conducted on 550 students of five schools for the deaf in Istanbul and Zonguldak, Turkey. Otologic, audiologic, dysmorphologic, ophtalmologic and dental examinations were performed in all children. Familial and medical histories were obtained. Results: The etiology of hearing loss was genetic in 346 (62.90%), acquired in 107 (19.45%) and unknown in 97 (%17.63) cases. A total of 619 malformations were defined in 550 children and 99 of them belonged to a syndrome. We identified 33 different syndromes for these 99 syndromic children. Syndromic etiology was found in 18.0% of the total and 28.61% of the subjects with genetic etiology. Most common syndrome was Waardenburg syndrome which occurred in 33 children. Conclusion: The incidence of hereditary hearing impairment is very high in developing countries compared to developed countries. Prevention is essential to reduce the incidence, multidiciplinary approach and genetic counselling are necessarry in this regard.
