The LAUP (laser assisted uvulopalatoplasty) is a modified UVPP with a shorter time required for surgery and carried out as outpatient treatment. Reduction in snoring and a therapeutic effect on OSA (obstructive sleep apnea) has been demonstrated. This retrospective study was intended to clarify which reduction in snoring can be achieved and which complications may appear when getting outpatient treatment and when under local anesthesia.
