Introduction. Surgical treatment of OSAS is focused on removal of narrowing that increase airway resistance in upper respiratory tract. Nd:YAG laser beam penetrates deeper into tissue than CO2 laser followed by superior scarification ability. In this study we investigate efficacy of surgery with Nd:YAG laser assisted uvuloplasty (LAUP). Material and methods. The subject was 51 patients with OSAS treated in Department of Otolaryngology, Medical University of Gdansk during the 2004–2005 period. All patients underwent all-night PSG and the ESS (Epworth Sleepiness Scale) score was used to assess the daytime sleepiness. Surgery treatment was performed and all patients underwent LAUP and additionally lingual base laser vaporization, tonsillectomy and nasal surgery where needed. The postoperative control ENT examination including ESS and all-night PSG was performed after 6 months. Results. Success was found in 29 patients, they achieved AHI<10 and ESS<12. In another 22 patients improvement at PSG parameters and ESS score were evaluated but they were still beyond normal range. Success was obtained in 14/16 patients with preoperative AHI I degree, 10/19 AHI II, and 4/16 AHI III. Nasal surgery for enlargement of airway passage was performed more frequently (25/32) in the group with success then in the group with partial improvement (9/19). Preoperative PSG parameters were better in patients with nasal obstruction. Patients with BMI≥30 succeeded rarely (10/22) in compare with patients with BMI<30 (success in 24/29). Preoperative PSG parameters were better in patients with BMI<30. Conclusion. LAUP with Nd:YAG laser wit additional tonsillectomy, lingual base surgery and nasal surgery were needed is successful method for surgery at light and medium stage of OSAS in nonobese patients.

The purpose of this paper is to present the possibilities associated with the use of remote sensing methods in identifying human emotional states, and to present the results of the research conducted by the authors in this field. The studies presented involved the use of advanced image analysis to identify areas on the human face that change their activity along with emotional expression. Most of the research carried out in laboratories is limited to the segmentation of the analyzed image, and then studying the changes in specific segments, so we have to deal with averaging information which is contained in the processed image. In the following sections we have described a method of acquiring and processing images of the human face, recorded by the Phantom MIRO 310 camera, for presenting specific states of the human brain while the emotional state is changing. Each emotion was expressed for 2 seconds. The resulting images are of a high technical quality and represent a series of frames recorded at the speed of 1000 frames per second. The method presented is based on assumptions drawn from Particle Image Velocimetry (PIV) which is well known in the field of fluid dynamics. The tracking algorithm lets us trace all identified objects on the human face and calculate different statistics. Thus we may identify some patterns created by moving objects on the face, which might be useful in the process of recognition of different emotional states.
