title: Surgical management of pneumosinus dilatans frontalis in the setting of chronic rhinosinusitis and type III frontal Cell.
abstract: Pneumosinus dilatans (PD) represents a rare lesion of unknown etiology in which progressive enlargement of an air-filled paranasal sinus results in cosmetic and functional complications. The absence of pathologic mucosa has traditionally been considered a hallmark of this disorder. A 24-year-old man presented with 2 years of chronic rhinosinusitis and recurrent, acute episodes of severe forehead pain with worsening outward prominence of the frontal sinus during air travel. Computed tomography and findings at surgery were notable for diffuse nonpolypoid inflammatory changes of the paranasal sinuses, a type III frontal sinus cell, and PD of the frontal sinus with severe deformity and thinning of the anterior table. A bicoronal approach was used for frontal sinus obliteration and cranioplasty. Excellent cosmetic and functional results were noted at the last follow-up. To our knowledge, this is the first report of PD frontalis presenting in the setting of chronic rhinosinusitis. Surgical management of this disorder requires consideration of both the functional and cosmetic issues.
