[Acquired enophthalmos associated with hypoplasia of the maxillary sinus and asymptomatic chronic maxillary sinusitis].

BACKGROUND

We report a case of progressive enophthalmos, maxillary sinus hypoplasia and radiological signs of sinusitis in a young woman.

CASE REPORT: The patient had no history of sinus surgery or facial trauma. There were no signs of sinusitis. Functional endoscopic sinus surgery was proposed to restore the communication between the nose and the antrum. DISCUSS: The particular aspects of asymptomatic maxillary sinus and causes of maxillary sinus hypoplasia are discussed. We suggest that obstruction of the osteomeatal complex causes negative pressure in the maxillary sinus provoking bone alterations. These alterations cause the maxillary sinus hypoplasia and the enophthalmos.
