Unpredictable results of laser assisted uvulopalatoplasty in the treatment of obstructive sleep apnoea.

چکیده
BACKGROUND Laser assisted uvulopalatoplasty (LAUP) is increasingly offered for the treatment of obstructive sleep apnoea (OSA), although there is a lack of objective data to support its indications and efficacy. A study was undertaken to determine the treatment response to LAUP. METHODS Overnight polysomnography was performed before and at least three months after surgery in 44 consecutive patients with symptomatic mild to moderate OSA (apnoea + hypopnoea index (AHI) >10/h). Pharyngeal dimensions were measured by videoendoscopy (n = 11) and disease-specific quality of life, sleepiness and snoring frequency (n = 16) before and after surgery were determined in subgroups of patients. LAUP was performed under local anaesthesia as a one stage resection of the uvula and soft palate by one of two experienced otolaryngologists. RESULTS Twelve patients (27%) had a good response (AHI 50% of pre-LAUP value); and 13 (30%) patients were worse (AHI >100% of pre-LAUP value). The velopharyngeal cross sectional area and anteroposterior diameter increased following LAUP (p<0.05). Quality of life indices improved significantly in all domains and sleepiness decreased. The snoring index did not decrease significantly. No preoperative anthropometric or videoendoscopic measures were predictive of a good response to LAUP. Patients who were worse after LAUP had milder baseline apnoea severity than those in the other response groups. CONCLUSIONS The treatment response to LAUP is variable and unpredictable, and only a few patients achieve a satisfactory response. There appears to be no relationship between subjective and objective measures of treatment efficacy.

Laser-assisted uvulopalatoplasty for snoring: does it meet the expectations?
The high prevalence of habitual snoring (35% of the general population) and the increasing demand for an effective treatment have led, in the last decade, to the generalisation of laser-assisted uvulopalatoplasty (LAUP). However, acceptable studies on its effectiveness are lacking. The present randomised, placebo-controlled study included 25 nonapnoeic and mild obstructive sleep apnoea snorers ...

Obstructive sleep apnea syndrome (OSAS) is a serious disease. The etiology of and optimum therapy options for this disorder have been much discussed and have been the subject of many publications. One much discussed therapy option is laser-assisted uvulopalatoplasty (LAUP). Despite conflicting opinions and guidelines which recommend that it should not be used, it remains in use. Patients who ha...

Laser-assisted uvulopalatoplasty (LAUP) was widely performed in 1990s as a surgical therapeutic procedure to improve snoring or mild obstructive sleep apnea (OSA). However, LAUP is not currently recommended as a treatment for OSA because the evidence for its efficacy is insufficient. Little is known about alternative minimally invasive surgery in patients who refuse continuous positive airway p...
