Laser modelling of costal cartilage implants (grafts) of a given shape is a new promising technology in laser medicine. When the final shape of an implant is formed with a surgical scalpel, residual stresses lead to the distortion of the implant and decrease its survivability after the surgery. Laser-induced relaxation of the interstitial residual stresses without disturbing tissue functionality opens new possibilities for a wide range of implantology problems.This article is devoted to a new laser method of treatment of laryngeal stenosis using lasermodelled costal cartilage grafts for the closure of laryngotracheal defect in patients. The paper discusses the physical ground of the applied laser modes when the stresses at the graft borders are minimal which provides positive impact on the survival of the laser-modelled cartilage. The results of the first clinical application of this method are presented.

Clinical results on sparing laser reshaping of nasal septum cartilage are reported for the first time. 40 patients have been treated with holmium laser to correct a deformed cartilage. The laser reshaping is a bloodless, painless procedure which takes few minutes to straighten nasal septum. The stability of the new shape and possible side effects have been examined during twelve months. The headache and other negative symptoms have disappeared, as a result of laser treatment for the most of patients. Rhinoscopic examination show an excellent long-term reshaping effects for nasal septum of 23 patients, and, also, good results for other 12 patients. For 5 patients only a little effect takes place. Our rhinomanometric examinations demonstrate a pronounced improvement ofthe breathing for 35 patients. No visible undesirable side effects was observed for all patients underwent to laser reshaping procedure.

The results of recent study of cartilage reshaping in vivo are reported. The ear cartilage of piglets of 8-1 2 weeks old have been reshaped in vivo using the radiation of a holmium laser. The stability of the shape and possible side effects have been examined during four months. Histological investigation shown that the healing of irradiated area could accompany by the regeneration of ear cartilage. Finally, elastic type cartilage has been transformed into fibrous cartilage or cartilage of hyaline type.

Хронический тонзиллит занимает значимое место в структуре оториноларингологической патологии. Наиболее важным этиотропным фактором развития данного заболевания являются β-гемолитические стрептококки группы А. В ряде случаев клинические проявления хронического тонзиллита практически не беспокоят пациента, что не исключает формирования метатонзиллярных осложнений и в целом негативного влияния на организм человека. Способ лечения больных хроническим тонзиллитом определяется формой заболевания. При декомпенсации процесса показана тонзиллэктомия, при компенсированной форме проводится консервативное лечение. Одним из основных методов терапии является промывание лакун миндалин. С этой целью возможно применение отечественного антимикробного препарата Диоксидин. Препарат обладает избирательной активностью в отношении различных патогенов: бактерий, вирусов, грибов, простейших, в т. ч. Streptococcus pyogenes, Staphylococcus aureus, Streptococcus pneumonia, Staphylococcus epidermidis, Haemophilus spp. и пр. Опыт использования Диоксидина для лечения патологии лор-органов свидетельствует о высокой эффективности и безопасности препарата при местном использовании.
