Pneumosinus dilatans: Our experience and literature review

Abstract

Pneumosinus dilatans (PSD) is a rare disorder that causes aberrant paranasal sinus dilation. Pneumosinus dilatans is typically benign and asymptomatic, without any evidence of bone destruction or pathologic changes in the underlying mucosa. Localized discomfort, headaches, facial paraesthesia and deformities, sensory deficits, olfactory loss, and ocular abnormalities are common complaints. The diagnosis of PSD is confirmed by the radiological investigations. The surgical treatment’s objective is to return both form and function of the affected sinus to normal. We briefly present our experience with pneumosinus dilatans and discuss the characteristics of this disease based on the specialised literature.

“…A pneumocele is an aerated sinus extending beyond the sinus's normal anatomic boundaries with displaced sinus walls. Its invasive characteristics can differentiate it from PSD, leading to focal or generalized bony sinus wall thinning and erosion while hypersinus causes the increased size of a sinus cavity but within the normal range of the affected bone and with normal sinus walls ( 10 ).…”
