METHOD OF TREATING ODONTOGENIC PERFORATIVE MAXILLARY SINUSITIS Russian patent published in 2011 - IPC A61B17/24 

FIELD: medicine.

SUBSTANCE: invention relates to field of medicine, namely to otolaryngology and maxillofacial surgery and can be used for treatment of inflammatory lesions of paranasal sinuses, accompanied by oroantral communication. Essence of the method lies in micro- maxillary sinusotomy by cutting mucous membrane to periosteum around oroantral fistula and cutting out mucoperiosteal flap from the side of mouth vestibule to mucogingival fold. Mucoperiosteal flap is separated from canine fossa, hole is made in anterior wall of sinus, endoscope is introduced, revision of sinus is carried out, foreign bodies, caseous and fungal masses are removed, sinus is washed with physiological solution, flap edge is deepithelised, captured with ligature, flattened over fistula opening, pulled under separated mucous membrane on palatine side and sewn. Silk or lavsan sutures are applied on flap edges. Mill hole has diametre 6-8 mm, in it endoscope is introduced and sinus revision, cleaning and washing are carried out. After performing plasty with flap, two injections of perfluorane in dose 2 ml are made into its base and one injection of perfluorane in dose 2 ml into mucous membrane of hard palate, indenting 10 mm from wound. Middle nasal passage is examined through nasal cavity, if its diametre is smaller than rhynoscope diametre, widening of maxillary sinus mouth to 5 mm is performed, pathologically changed mucous membrane in area of middle nasal passage and in nasal cavity is removed, sinus is punctured, catheterised and filled with 10 ml of perfluorane. In the following two days perfluorane injections are repeated one time per day, sinus is washed with 100 ml of physiological solution. After that 20 ml of air are introduced into it, sinus is filled with 10 ml of perfluorane.

EFFECT: invention allows to cover oroantral fistula reliably and restore function of maxillary sinus, as well as reduce terms of treatment and rehabilitation of patients with said pathology.
