Abstract

PURPOSE
Pnumosinus dilatans is a rare disease that one or more of the paranasal sinuses are dilatated without functional alteration. The most frequently involved sites are frontal and sphenoid sinus. Facial asymmetric contour is the most common signs and nasal obstruction and pain may be combined. The purpose of reconstruction of pneumosinus dilatans is two-fold, to re-establish a permanent pressure equilibrium of sinus and to correct the possible facial deformities. METHODS: We present a case of a 24-year-old female with a 7-year history of protrusion of right malar region. Plane radiography and computed tomography detailed an abnormal expansion of the right maxillary sinus without thinning of bony wall, leading to diagnosis of maxillary pneumosinus dilatans. Surgical decompression and maxilloplasty were achieved by ostectomy of anterior wall of maxillary sinus and repositioning of removed bony fragment with miniplate.
RESULTS
Post operative course was uneventful without complication and malar height became symmetric by physical and radiologic examination.
CONCLUSION
We corrected successfully pneumosinus dilatans of maxillary sinus by surgical decompression and maxilloplasty. For this case, we reviewed literature related to this topic.
