The occurrence of an isolated schwannoma in the olfactory groove is extremely rare. We herein present 2 cases of schwannomas in the olfactory groove that were treated with endoscopic excision. In these 2 cases, the tumor originated in the cribriform plate and cerebrospinal fluid rhinorrhea occurred after tumor resection, which was repaired using tissue grafts.
