Pneumosinus dilatans: Our experience and literature review

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.
