Abstract
To compare postoperative patient discomfort, voice quality, and procedure time and cost for removal of recurrent respiratory papillomas using the microdebrider versus the CO2 laser. A randomized prospective study comparing children undergoing excision of recurrent respiratory papillomas by CO2 laser versus excision by microdebrider. For the 6-month study, patients for whom removal of recurrent respiratory papillomas was indicated were randomly assigned by birth year to microdebrider or CO2 laser therapy. Disease severity was scored as the sum of ratings of 1+ (minimal), 2+ (moderate), or 3+ (severe) for involvement of 27 areas of the aerodigestive tract by direct microlaryngoscopy immediately before treatment. Parents scored patient discomfort and improvement in voice quality 24 hours after surgery, using a 5-point (0 = no pain; 4 = worst pain) and a 10-point (1 = minimal change; 10 = significant improvement) scale, respectively. Nineteen patients ranging in age from 2.5 to 20 years underwent 32 procedures in all. Groups did not differ significantly in age, sex, or severity of disease. For disease of equivalent severity, microdebrider treatment was associated with equivalent 24-hour-postoperative pain scores, greater improvement in voice quality, shorter procedure times, and lower overall procedure cost. Immediate postoperative results indicate that the microdebrider may be as safe as and, at some institutions, might be more cost-effective than the CO2 laser for removal of recurrent respiratory papillomas.
