Abstract

The role of endotracheal intubation on general anesthesia and maintenance of artificial airway has been increased todays. However, despite of improvement in the technique for intubation and preventive methods for complications, there is no corresponding evidence of decreasing in the incidence of complication ; abrasion edema, ulceration, granuloma, stenosis, etc. From 1982 to 1992, the authors had experienced 16 cases of intubation granuloma, and following results were obtained. Age distribution was mostly in the 20 to 49 years old group(84%). The result of sex frequency explains that the proportion of male to female showed a ratio of 7 to 1. Main symptoms were hoarseness in 12 cases(75%)，foreign body sensation in 2 cases (12%), dyspnea in 1 case(6%), sore throat in 1 case(6%). The side of lesion was bilateral in 6 cases(37%) and unilateral in 10 cases(63%). Unilateral occurence was left in 3 cases(30%) and right in 7 cases(70%). The locations of intubation granuloma were vocal process of arytenoid cartilage in 8 cases(50%), post 1/3 of vocal cord in 6 cases(37%) and middle 1/3 of vocal cord in 2 cases(12%). The duration between extubation and onset of symptom in less than a month was most frequent as 7 cases(44%) out of 16 cases. The most common cause of previous operation was cesarean section as 6 cases(37%). Mean duration of intubation time was 2 hours and 5 minutes. Composition of used intubation tube was red rubber tube. 1 case(6%) was recurred and recovered by conservative treatment.
