We analyzed 105 cases of benign laryngeal diseases which caused hoarseness and were treated with classic laryngeal microsurgery or C02 laser microsurgery at the department of otolaryngology, Chunan hospital, College of Medicine, Soonchunhyang University from January 1995 to June 1996.
The results were as follows;
The ratio between male and female was 1:1.5. And fifth decade was the most frequently affected and average age was 42.0 years old.
In occupation, it occurred in house wife, farmer and the office man in order. And the symptom duration was 1.5 years in average.
In a side, both were 37.1%, right side 32.4% and left side 30.5%. And there was smoking history in 30.5% and vocal abuse history in 31.4%.
In disease, a polyp was the most common(44.8%) and a nodule was 27.6%, intracordal cyst 13.3%, papilloma 4.8% and intubation granuloma 1.9%.
Average operation time was 16.8 minutes in classic laryngeal microsurgery and 22.0 minutes in C02 laser microsurgery. There was no significance statistically.
In classic laryngeal microsurgery, satisfactions were 53.0%, better than before 33.4%, no difference 12.1 %, worse than before .1.5%. In C02 laser laryngeal microsurgery, satisfactions were 43.6%, better than before 43.6%, no difference 10.3%, worse than before 2.6%. Nevertheless, there was no significance statistically.
Finally, the result of the present study suggested that the application of classic micro-laryngeal surgery and C02 laser microsurgery in therapy of various benign laryngeal diseases was established as no significant differences between both of them, yet.
