The hypoplastic maxillary sinus and the orbital floor.
OBJECTIVE
Hypoplastic maxillary sinus is a relatively rare clinical problem that has a variable presentation. The purpose of this article is to review the recent literature with regard to evaluation and treatment.


RESULTS
Most authors suggest that hypoplastic maxillary sinus results from the development of negative pressure resulting from an obstruction of maxillary sinus ventilation. Patients most frequently present with unilateral enophthalmos but some cases may be identified incidentally on imaging studies.


CONCLUSIONS
Hypoplastic maxillary sinus is a rare clinical entity with variable presentation. Evaluation and management are tailored to each individual patient's degree of disease and symptoms.
