Abstract
Laser surgery has been proven a valuable tool in treating recurrent chronic-polypous sinusitis when conservative treatment is ineffective. As thermic ablation is one of the key principles, the question remains whether wound healing in the mucosa is prolonged or results in superficial scarring. After 143 Neodymium:YAG laser procedures for the ablation of recurrent polyps under local anesthesia, 14 biopsies were taken during an interval of 6 days to 2 years from the laser-treated mucosa. All were examined histologically. 16 biopsies were taken from patients after conventional endonasal microscopic sinus surgery. All patients had been followed up by regular endoscop employing a combined anti-inflammatory, anti-allergic drug regime. In the laser-treated group, 5 of 14 cases showed a prolonged inflammatory reaction including submucosal edema, granulocyte infiltration for up to 3 to 4 months, while the control group tended to show submucosal lymphocyte infiltration and formation of collagenous tissue in 6 of 16 cases. The interval of 8 months average, which eventually leads to restitution of respiratory epithelium, is the same in both groups. While wound healing is comparable to conventional surgery, laser surgery has the advantage of being a minimally-invasive out-patient procedure, which helps to avoid extensive conventional revision surgery.
