FIG. LEGENDS
Fig. 1. Transseptal approach started from posterior septectomy after elevating septal flaps (A), with olfactory nerves protected (B; arrowhead: olfactory nerves). The rostrum was removed (C), followed by tumor resection until the arachnoid membrane descended (D).
Fig. 2. Postoperative Lund-Kennedy scores (A) and 22-item sinonasal outcome test (SNOT-22) scores (B) were significantly lower in the transseptal group, while olfactory test revealed no significant difference (C). *P < . 05; **P < . 01; ***P < . 001
