We aimed to present the clinical characteristics of a patient who had bilateral sinocutaneous fistula as a complication of longstanding frontal sinusitis in this study. A 48-year-old man presented with bilateral sinocutaneous fistula located adjacent to the superior palpebral sulcus on the orbital midline. Ophthalmological and nasal endoscopic examinations were nonspecific. Computerized tomography (CT) demonstrated bilateral mucosal thickening, loss of aeration, and full-thickness bone defect on the infero-anterior part of the right frontal sinus corresponding to the discharging fistulous track. On the left side, symmetrical bone defect was partially closed. Interestingly, the patient had no other systemic symptoms or findings for eight years. In conclusion, frontal sinusitis might lead serious complications, whereas sinocutaneous fistulas might act as secondary drainage pathway that prevents intracranial or orbital complications as in this case.

Kirk sekiz yasinda erkek hasta orbital orta hatta superior palpebral sulkusun hemen yakininda yer alan iki tarafli sinokutanoz fistul ile basvurdu. Oftalmolojik ve nazal endoskopik muayeneler olagandi. Bilgisayarli tomografide (BT) bilateral mukozal kalinlasma, havalanma kaybi ve sagda, akintili fistul alanina uyan, frontal sinus alt-on duvarinda tam kat kemik defekti saptandi. Sol tarafta, simetrik kemik defekti kismen kapaliydi. Ilginc olarak, hastanin sekiz yildir herhangi bir sistemik yakinmasi veya bulgusu mevcut degildi. Sonuc olarak, frontal sinuzit ciddi komplikasyonlara yol acabilmektedir, ancak bu olgudaki gibi sinokutanoz fistuller ikincil drenaj yolagi seklinde rol oynayarak intrakranial veya orbital komplikasyonlarin onune gecebilirler.
