METHOD OF TREATING ODONTOGENIC MAXILLAR SINUSITIS WITH OROANTRAL FISTULA Russian patent published in 2014 - IPC A61N5/67 A61L15/44 A61B17/24 

FIELD: medicine.

SUBSTANCE: postoperative period involves tamponage with Coletex-AGGDM wet tissue within middle nasal passages. The tamponage area is exposed to laser light in the infrared band at a wave length 0.95 mcm at the output power of 2-3 mWt for 4-5 min. After the exposure, the tissue is left for one day. The following procedures are performed with the tissues placed in the middle nasal passage within a natural fistula and on a mucous membrane of a hard palate in a projection of a maxillary sinus bottom. The tamponage area and skin in the projection of the maxillary sinus within an anterior sinus wall are exposed. 2-3 procedures are performed at the output power of 5-7 mWt for 7-10 min for one field. 4-6 procedures are performed at the power of 15-20 mWt for 3-10 min for each field. After the exposure is terminated after each procedure, the endonasal tissue is left for 6-8 hours.

EFFECT: method enables providing higher clinical effectiveness by antibacterial, antiseptic, anti-oedematous effects, recovering the ciliary transport function without injuring the ciliated epithelium; eliminating the postoperative complications, such as sinus bleeding and cicatrical deformity of the mucous membrane.
