Informed consent for septal surgery: the evidence-base.

Informed consent is becoming an increasingly important issue in patient care. Inherent in this is the ability to accurately inform patients of the risks and complications involved in surgery. Nasal septal surgery is commonly performed by otolaryngologists and although often considered routine has a number of recognized complications that can have a significant effect on life quality. We carried out a review of the literature over the last 25 years and reviewed studies quoting rates of complications after septoplasty and submucous resection (SMR) using strictly applied criteria for study inclusion. There was a paucity of prospective data, especially for the cosmetic effects of septal surgery. Rates of septal perforation were two to eight per cent for SMR and 1.6-5.4 per cent for septoplasty. The incidence of cosmetic deformity was low for both procedures zero to one per cent. More well-designed studies are required to augment the current evidence base. While this does not replace the need for surgeons to audit their own results it provides evidence-based information to assist in the process of informed consent.
