Abstract

A forty-one-year-old man presented with right-sided Progressive facial nerve paralysis of one year duration. Computed tomography of the temporal bone showed a soft tissue mass in relation with the tym- panic segment of the facial nerve with destructive changes in the facial recess region. Magnetic reso- nance images before and after gadolinium injection revealed a contrast-enhancing mass lesion in the tympanic cavity. The tumor was removed through a transmastoid approach and a cable graft from the greater auricular nerve was used to repair the defect.Histopathologic diagnosis was facial nerve schwannoma. At the end of one-year follow-up, the patient had moderately severe facial nerve dysfunction.

Intratemporal fasyal sinir nöromu: Olgu sunumu

Abstract

Kırk bir yaflındaki erkek hasta, sol tarafı tutan, bir yıl- dır yavafl geliflim gösteren fasyal paralizi flikayeti ile baflvurdu. Temporal kemik bilgisayarlı tomografisinde fasyal sinirin ikinci dirseği hizasında, orta kulağa doğ- ru uzanan ve fasyal reses bölgesinde tahrip edici de- ğifliklere yol açan yumuflak doku kitlesi görüldü. Ga- dolinum ile yapılan menyetik rezonans görüntüleme- de orta kulak boflluğunda kontrast madde tutan kitle saptandı. Transmastoid yolla girilerek, fasyal sinirdeki kitle cerrahi sınırlarda rezeke edildi ve n. aurikularis magnustan alınan sinir grefti ile tamir edildi. Histopa- tolojik incelemede fasyal sinir schwannomu tanısı kondu. Ameliyattan bir yıl sonra yapılan incelemede fasyal sinir fonksiyonunda kısmi düzelme görüldü
