Otorhinolaryngologic complications of endoscopic surgery of the skull base were divided according to the location of morbidity: donor area refers to the mucosa and the nasal septum and represents the main complaints of patients after surgery, including synechiae, internal nasal valve alterations, mucocele, septal perforation, and olfactory alterations. Receptor area refers to the location of the defect in the skull base and the barrier to be created to prevent communication between sterile and contaminated areas, in which the most severe complications are observed, such as cerebrospinal fluid leak and meningitis. The integrity of the nasoseptal flap was observed in all patients in the present study. NC, no complications.
