Facial pain following sinonasal surgery or facial trauma.

The case notes of 22 patients who reported facial pain after sinonasal surgery or trauma out of a cohort of 973 patients seen in a rhinology clinic were reviewed retrospectively. This group included 10 patients who had undergone endoscopic sinus surgery and four who had suffered facial fractures. None of the patients reported any facial pain before surgery or trauma. In only one case was there any evidence, clinically, endoscopically, or radiologically, of any paranasal sinus disease and when this resolved with nasal medical treatment the pain remained. The treatment of these patients' facial pain centred on the use of neurological medical treatment. One third of the patients responded to low-dose amitriptyline, a further third showed some response to other pharmacological agents including carbamazepine, and the remaining third showed no response. These cases illustrate the characteristics and management of facial pain after sinonasal surgery and highlight the importance of medical neurological treatment in the absence of any objective evidence of sinus disease.
