The use of intranasal steroids by otolaryngologists in the treatment of patients with infective rhinosinusitis and after endonasal surgery, particularly endoscopic sinus surgery, is unlicensed, as stated in the British National Formulary and in the manufacturers' leaflets supplied with nasal steroid medications.

This article reviews the current medical literature regarding this topic and aims to clarify whether intranasal steroid usage in these circumstances should be recommended.
