title: [An extensive case of maxillary pneumosinus dilatans].
abstract: We present a 40-year-old male with an aggressive case of maxillary pneumosinus dilatans. Our examination including rhinoscopy showed that the nasal wall including the middle turbinate was displaced towards the nasal septum obliterating the middle meatus. A reopening of the affected maxillary sinus was performed endoscopically with success. At the follow-up examination and exposure to high altitude simulation in an underpressure chamber 15 months postoperatively the patient had no symptoms and there were no signs of exopthalmus or facial swelling.
