The objective of this study was to perform translation, cross-cultural adaptation, and validation of the SNOT-22 in the Lithuanian language. This is a prospective case-control study. The study was conducted at the University clinic. The sino-nasal outcome test 22 (SNOT-22) was translated into the Lithuanian language; the pilot study involved 34 patients, the test-retest group consisted of 34 patients with chronic rhinosinusitis (CRS), and the control group of 115 patients with no CRS complaints; 36 patients were evaluated before surgery and 3 months after surgery. The results showed a good internal correlation with Cronbach's alpha-0.89 in the initial test, and 0.93 in the retest; both values suggesting good internal consistency within the SNOT-22. Pearson's correlation coefficient was 0.72 (p < 0.001), revealing good correlation between the initial scores and the retests scores. Our sample of healthy individuals had a median score of 12 points, and the instrument was capable of differentiating between the healthy and the patient group, demonstrating its validity (p < 0.0001). The statistically significant reduction in the post-operative scores, vis-à-vis pre-operative values, demonstrates the responsiveness of the instrument. The minimally important difference was 13 points in the SNOT-22 score. The Lithuanian version of the SNOT-22 is a valid instrument for assessing patients with CRS. It demonstrated good internal consistency, reproducibility, validity, and responsiveness.

A total of 37 primary snoring and obstructive sleep apnea hypopnea syndrome (OSAHS) patients were treated with two sessions of radiofrequency tissue ablation (RFTA) to assess the relationship among RFTA and sleepiness, anxiety and depression in patients with OSAHS. Patients' sleepiness was rated according to the Epworth sleepiness scale (ESS), anxiety--on Spielberg's trait-state anxiety inventory scale and depression degree--with Beck depression inventory-second edition scale and the patients' major complaints were evaluated using visual analog scales before and after the treatment. A remarkable decrease in patients' complaints, sleepiness and depression after RFTA was observed. The ESS mean score decreased from 9.3 +/- 3.4 to 7.14 +/- 3.2 points (P < 0.05) and Beck depression index mean value decreased from 14.2 +/- 10.8 to 8.7 +/- 7.6 points (P < 0.05), respectively. RFTA is a treatment of choice for snoring and mild to moderate OSAHS. Reduction of sleepiness and depression was statistically significant after RFTA.

Combined RF-UPP showed to be effective in the treatment of snoring and mild to moderate OSAS overcoming the RFT alone.

Snoring and mild to moderate OSAHS patients have resemblances in their distinctive anatomical and clinical properties. This group of the patients revealed mild depression and moderate trait anxiety scores when measured with the BDI-II and STAI, which correlated significantly with the severity of the patients' daytime complaints measured with the VAS.

Based on present study results, we conclude that RFTA therapy results in improved depression scores for the bed partners of snoring and OSAHS patients during a short follow-up period, as measured with BDI-II.
