Failures in snoring and OSAS surgery

Significant reduction of snoring noise and valid prevention of neurological and/or cardiovascular complications of OSAS are the basic goals of all modern snoring and OSAS surgical procedures. 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.
