Schwannomlar periferik sinir schwann hücrelerinden kaynaklanan benign tümörlerdir. Baş ve boyun bölgesinde yaygın görülürler. Orta kulakta nadir görülmekle birlikte paragangliomalardan sonra ikinci en sık benign orta kulak tümörüdür. Orta kulakta en sık fasiyal sinirden ve korda timpani, stapedial sinir gibi dallarından kaynaklanır. Fasiyal sinir kaynaklı schwannomlar fasiyal sinir semptomlarından ziyade iletim tipi işitme kaybına neden olur. 3 ay önce gelişen periferik fasiyal paralizisi olan 59 yaşında erkek hastanın, yaklaşık 10 yıldır sol kulakta işitme kaybı yakınması mevcuttu. Yapılan radyolojik incelemelerde sol orta kulak boşluğunu tama yakın dolduran yumuşak doku dansitesinde, glomus tümörü, enflamatuar değişiklikler düşündüren patolojik görünüm mevcuttu. Hastaya timpanomastoidektomi yapıldı. Orta kulağı dolduran mavi morumsu renkte kitle izlendi. Kitlenin patolojik tanısı schwannom olarak rapor edildi. Bu sunuda nadir görülen bir orta kulak benign tümörü olan schwannom olgusu sunuldu

Schwannomas are benign tumors originating from peripheral nerve, schwann cells, and located in head and neck region commonly. They are the second most common middle ear tumors after paragangliomas, and they may often arise from the facial nerve and also from its branches such as the chorda tympani and the stapedial nerve. Facial nerve schwannomas cause conductive hearing loss rather than usual symptoms of facial nerve. Our patient was 59-year -old man, who had hearing loss on his left ear for 10 years and who had facial paralysis for 3 months before coming to our clinic. Temporal bone computerized tomography scan showed soft tissue mass involving the timpanic cavity completely, which suggest glomus tumor or inflamatory changes. Tympanomastoidectomy operation was performed. The histopathological diagnosis of the mass was reported as schwannoma. In this case, we presented the schwannoma as a rare benign tumor of the middle ear.
