Bilateral Pneumosinus Dilatans of the Maxillary Sinuses with Facial Pain / 대한이비인후과학회지

ABSTRACT

Pneumosinus dilatans is a rare disease in which 1 or more paranasal sinuses are dilated without functional alteration. The frontal sinus is the most commonly affected site, with involvement of the maxillary sinus being rare. A 25-year-old man had complained of facial pain and headache of frontal area. These symptoms were aggravated after nose blowing. A computed tomographic scan showed a hyperaeration of both maxillary sinus and frontal sinus. We treated the condition by endoscopic sinus surgery (middle meatal antrostomy, both). Just after operation, facial pain and headache of frontal sinus have subsided. No recurrence was detected. In this article, the authors present surgical options for the treatment of pneumosinus dilatans of the maxillary sinus, including a review of the literature.
