[Low-intensity helium-neon laser in the treatment of patients after endonasal dacryocystorhinostomy]

Described in the paper is an efficiency study of using, postoperatively, the low-intensity helium-neon laser (LIHNL) in patients with obstruction of the lacrimal tracts. Eighty patients were examined after endonasal dacryocystorhinostomy. They were shared between 2 groups with respect to a postoperative course: group 1--experimental, 40 patients, and group 2--control, 40 patients. The experimental patients received, apart from the traditional postoperative therapy, a course of LIHNL therapy. The controls received only the traditional postoperative treatment. The efficiency of postoperative treatment was evaluated by clinical, instrumental and laboratory examination methods. The study denoted that the use of LIHNL in the early postoperative period after endonasal dacryocystorhinostomy had a pronounced anti-inflammatory effect, speeded up the wound healing, prevented the growth of granulation tissues and the merging of the shaped lacrimal-sac fistula with the nasal cavity. LIHNL contributed to a complete recovery of the functional activity of the nasal mucous tunic. Thus, the LIHNL therapy essentially facilitates the postoperative management of patients, cuts the rehabilitation period and enhances the treatment results.
