title: Laser-assisted surgery addressing snoring long-term outcome comparing CO2 laser vs. CO2 laser combined with diode laser.
abstract: Our study encompasses 61 patients (49 men--80.3%; 12 women--19.7%) treated from September 1998 through August 2001. Mean follow-up covers 25 months (range: 7-43 months). Our CO2-LAUP technique involves vaporizing the palatine mucosa along a rectangular surface from the palatal dimple to the base of the uvula; trimming the palatine arches under the velum; and resecting the uvula. For 22 patients, we employed intravelar diode laser coagulation in the expectation of reducing the postoperative pain whilst achieving the same therapeutic effectiveness. There is no pain difference between the CO2-LAUP technique versus that combining intravelar diode laser coagulation with CO2 laser uvula resection and trimming of the palatine arches. Mean maximal pain reaches 6.93 +/- 3.55 with CO2 laser and 6.95 +/- 3.64 with CO2 laser plus diode laser. Similarly, both techniques involve the same mean algesic period of 22 days with the day of maximal pain at 1 week after surgery. Associating base of tongue vaporization significantly increases the algesic period (p = 0.042). No long-term complications were observed in relation to intravelar coagulation or LAUP, whether combined or not with base of tongue vaporization. In terms of patients satisfaction, no significant difference exists between the various surgical techniques of the velum alone. The satisfaction rate reaches 5.26 +/- 3.92 with CO2 laser and 5.82 +/- 2.67 with the CO2 laser plus diode laser. Satisfaction is statistically identical when base of tongue vaporization is included in the procedure.
