Objective : To present data on ten years' experience in C0
2
laser surgery and associated
complications among otorhinolayngologic patients.
Material and Method : The study involved examining records of otorhinolaryngologic
patients who underwent C0
2
laser operations during a 10-year period (July 1, 1986 -June 30,
1996). The sample consisted of 733 patients: 370 male and 363 female patients. C0

laser
surgery in otorhinolaryngology was first used in Ramathibodi Hospital on July 10, 1986.
Results : These patients were aged 2 months to 93 years with the mean age of 24.3
years (median
=
16 years). Among 1, 725 operations, 1,570 operations (91%) were performed
under general anesthesia and 155 operations (9%) were performed under local anesthesia. In
our series, the most frequent sites for laser surgery were as follows: larynx (77.22% ), oral
cavity and oropharynx (12.64%), skin (5.04%) and nose and paranasal sinuses (3.31 %). Intra-
operative complications occurred in 18 out of 1,725 (intra-operative complication rate of 1 %).
Laser-related complications were found in 13 out of 1,725 operations (0.75%) and non laser-
related complications were found in 5 out of 1,725 operations (0.25%). There was no mortality.
Conclusion : C0
2
laser is a useful modality of treatment in otorhinolaryngologic
surgery especially in the larynx. Our experience demonstrates the relative low incidence of
complications ( 1%) and no mortality in otorhinolaryngology head and neck surgery.
