Abstract

Anosmia is one of the early symptoms of olfactory groove meningiomas (OGM) and the postoperative recovery of anosmia is accepted to be unexpected. A 42-year-old female patient presented with bilateral anosmia, and visual field field defects. Radiological examination revealed a large OGM with significant peritumoral edema. The tumor was totally resected through the pterional approach, with the meticulous preservation of the left olfactory nerve. Visual field disturbances improved in the early postoperative period. Furthermore, olfaction recovered in the left nostril at the 6-month follow-up. Despite the common belief that anosmia persists after OGM surgery, with preservation of ofactory nerves, olfaction can be recovered in rare cases.

Olfaktör oluk meningiomunun pterional yaklaşımla çıkarılmasından sonra anosminin düzelmesi

Abstract

Anosmi, olfaktör oluk meningiomlarının (OGM) erken belirtilerinden biridir. Ek olarak, anosminin, saptanması durumunda, operasyon sonrasında düzelmesi beklenmemektedir. Olgumuzda 42 yaşında kadın hasta, bilateral anosmi ve görme bozukluğu ile başvurmaktaydı. Radyolojik incelemelerde belirgin peritümoral ödem ile birlikte büyük bir OGM saptandı. Tümör, pterional yaklaşımla, sol olfaktör sinirinin korunmasıyla, total rezeke edildi. Postoperatif erken dönemde görme bozukluğu düzeldi. Ayrıca, 6 aylık takipte sol burundan koku duyusu alınması sağlandı. Buna göre, anosminin OGM cerrahisi sonrasında kalıcı olacağı yaygın kabul gören bir durum olsada, olfaktör sinirlerin korunması ile nadir vakalarda koku alma duyusu geri kazanılabilir.
