Abstract

Objective: Benign schwannomas are the most common tumour of the peripheral nerves. Symptomatic schwannomas are treated by surgical excision, but new neurological deficits may develop. We performeda retrospective review of cases of schwannomas in the extremities and reviewed the relevant literature.

Methods: We retrospectively reviewed the demographic characteristics of 11 patients with schwannomas treated at our institution. We also reviewed the clinical characteristics and postoperative results of these cases, determined the possible risk factors influencing the development of complications and compared the risk factors with those reported in the literature.

Results: There were five males and six females with a mean age of 37.6 (range: 17–62) years. The mean postoperative follow-up was 54.6 (range: 26–88) months. Three tumours were located in the forearm and the rest were localized in the lower extremity. No recurrences were observed during the follow-up period. New motor and sensory deficits were observed in only one patient.

Conclusion: Schwannomas in the extremities can be excised with acceptable risk of neurological deficits. Meticulous dissection is required during surgery.

Periferik sinir schawannomlarının cerrahi eksizyonu: On bir hastanın analizi

Abstract

 

Amaç: Benign shcwannom periferik sinirlerin en yaygın tümörüdür. Semptomatik schwannomun tedavisi cerrahi eksizyondur. Cerrahlar yeni nörolojik defisitlerin gelişme olasılığına hazırlıklı olmalıdır. Biz literatürle birlikte ekstremite schwannomlarını içeren olguların geriye dönük bir analizi yaptık.

 

Çalışma planı: Hastanemizde tedavi edilen 11 schawannomlu hastanın verilerini geriye dönük olarak inceledik. Klinik özellikleri ve ameliyat sonrası sonuçları gözden geçirdik ve komplikasyonların gelişimini etkileyen olası risk faktörlerini belirledik ve bunları literatürle karşılaştırdık.

 

Bulgular: Ortalama yaşın 37.6 (17–62) olduğu beş erkek ve altı kadın vardı. Ameliyat sonrası ortalama takip süresi 54.6 (26–88) aydı. Önkolda üç tümör tespit edildi ve diğer tümörler bacak alt kısmındaydı. Takip periyodunda nüks gözlenmedi. Bir hastada yeni motor ve duysal defisit gözlendi.

 

Çıkarımlar: Ekstremite schwannomaları kabul edilebilir nörolojik defisit riski ile eksize edilebilir. Cerrahi sırasında titiz bir disseksiyon gereklidir.
