Septal perforation and bilateral partial middle turbinate necrosis after bilateral sphenopalatine artery ligation

摘要

Objective: To report previously unreported complications of bilateral sphenopalatine artery ligation.Subjects and methods: We present the case of a 45-year-old man who underwent bilateral sphenopalatine artery ligation to control intractable posterior epistaxis. After four months, he re-presented with nasal obstruction and crusting.Results and analysis: Examination under general anaesthesia showed posterior septal perforation and bilateral necrosis of the lower parts of the middle turbinates. The necrotic parts were excised. The patient had no more complaints.Conclusion: Following sphenopalatine artery occlusion, ischaemic necrosis is a potential risk in anatomical areas that receive their only arterial supply from this artery. The staging of bilateral sphenopalatine artery occlusion needs to be studied.
