Spontaneous maxillary sinus rupture in the absence of pre-existing sinus disease: case report.

INTRODUCTION Spontaneous fracture of the maxillary sinus is usually associated with enophthalmos and pre-existing sinus disease. CASE REPORT We present a case of spontaneous maxillary sinus fracture without enophthalmos and with no preceding history of trauma or evidence of sinusitis. DISCUSSION The closest condition to that presented is silent sinus syndrome. The differences between our case and this syndrome are reviewed. There are no previously reported cases of lateral wall maxillary fracture and associated facial surgical emphysema following nose-blowing.
