Any kind of operation, single or multiple, included into a one-step or multistep programs, is said to fail if snoring is not reduced to a significant extent for the patient or if clinical and/or instrumental data after the operation show that Upper Airways Resistance Syndrome (UARS) or OSAS continues to be probably dangerous for the patient to some extent. The real figure of failures in different situations of sleep-disordered syndromes surgery is discussed, along with the possible explanations. A group of patients operated on for snoring and OSAS in our clinic is analyzed retrospectively from the subjective point of view and by means of sleep studies to get a precise quantitative and qualitative idea of the failed cases. The final goal would be to understand how it is possible to reduce to a minimal level the number of true failures.

Frequently, UA collapse occurs at the same time at different section levels. Identifying the site and the dynamic pattern of obstruction is mandatory in therapeutical decision-making, and in particular if a surgical therapy option is taken into account. Nowadays, awake fiberoptic nasopharyngeal endoscopy represents the first level diagnostic technique to be performed in such patients, but recently, the drug-induced sleep endoscopy (DISE) has been introduced to overcome the limits of the awake nasopharyngeal endoscopy. Whatever diagnostic tool we decide to use, one of the main problems encountered is the standardization of the description of the sites and dynamic patterns of UA collapses. In this paper, the authors describe the NOHL classification, which could be applied during awake and sleep endoscopy, and allows a simple, quick, and effective evaluation of grade and patterns of UA collapse, suggesting its application, especially in therapeutical decision-making and in the analysis of surgical outcomes.

The design was double-blind, multicentre and parallel-group randomised. Eleven Italian centres enrolled 144 patients: 75 of the patients were treated with betahistine (41 MD/34 PPV) and 69 with placebos (40 MD/29 PPV). The betahistine dosage was 16 mg twice per day for 3 months. Compared to the placebo, betahistine had a significant effect on the frequency, intensity and duration of vertigo attacks. Associated symptoms and the quality of life also were significantly improved by betahistine. Both the physician's judgement and the patient's opinion on the efficacy and acceptability of the treatment were in agreement as to the superiority of betahistine. The effective and safe profile of betahistine in the treatment of vertigo due to peripheral ...
