The Uvulopalatopharyngoplasty & Tonsillectomy Surgeries

All these methods induce nockring of the semi bats palate and thermal damage which may extend strong beyond the dotty palatalized tissues. Use of the CO2 laser technique differs from that of LAUP laser technique in that LAUP only produces scarring and shrink of the soft palate: no tissue is outside. The CO2 laser technique removes as much tissue as is removed with a scalpel in UPPP.

Looking at the formation of scar tissue after palatoplasty, Motegi, Matsuo, Ito, Azumi and Ueno (1995) gear up that scar formation in the palate and surrounding tissue is light when incisions atomic number 18 replicate to the long axis of the cleavage lines, but severe when incisions are made at right angles to the cleavage lines. In rough cases, jaw movement may be restricted by hypertrophic scar formation between the upper and lower alveolar consonant ridges following palatoplasty.

Snoring is usually created by vibration of the uvula, soft palate, and tonsillar pillars (Brown, Merrick and Peterson, 2002). A somnoplasty can be performed using radiothermy techniques to create a submucosal lesion in the soft palate using radiofrequency energy. The result is rigidifying and shortening of the palate and the uvula, which inhibits them from vibrating and so reduces snoring. Over a time period of trio to six weeks, the lesions is resorbed by the body, shortening the palate, but besides scar tissue formation occurs as with other palatal surgeries, resulting in stiffening of the soft palatal tissues.

Ducic et al (1996) compared LAUP with EAUP to see if there were any diseased or technical differences between the two techniques in an puppet model. They found no difference in the gross improve between the palates using either technique, but they consistently found that there was more thermal damage and scarring in the palates tough with LAUP than in those treated with EAUP.

EAUP was faster to perform, more hemostatic, associated with less cleaning woman formation, and had less histological evidence of thermal damage than LAUP.

The soft palates of patients with snoring and OSA retained their normal architecture and diseased changes were rare. more pronounced changes were seen in the samples from patients who had previously undergone LAUP. The changes involved all three layers of the soft palate and affected all dimensions of the oral side, farthest beyond the immediate range of the laser beam application. trivial ulcers were found, with interruption of the squamous epithelium, and polymorphonuclear leucocytes were often found at their base along the oral side. The lamina propria was changed the most, with dense fibrotic tissue composed of tightly set collagen fibers with few fibrocytes replacing the loose connective tissue throughout the layer.
