Method of draining the maxillary sinus for the treatment of maxillary sinusitis

摘要

Maxillary sinusitis is treated by placing a self-supporting temporary drain hose in a wall separating the sinus and a nasal cavity. The hose allows drainage from the sinus, and repeated rinsings without the need of further operations. Between rinsings, air enters the sinus through the hose and kills bacteria therein.
