Abstract:
BACKGROUND: Intubation granuloma of the larynx occurs from direct mechanical irritation of mucosa from a traumatic or prolonged endotracheal intubation. Surgical excision can be accomplished with microlaryngeal instruments or with CO2 laser under general anesthesia. OBJECTIVE: To investigate clinical characteristics of intubation granuloma and to suggest a jet ventilation technique appropriate in general anesthesia. MATERIAL AND METHOD: The clinical presentation, management of 14 consecutive cases of intubation granuloma were reviewed retrospectively from August, 1989 to December, 1995. RESULTS: 1) Age distribution was mostly in the 20-49 years old group(86%). The ratio of male to female was 2:12, with female predominance. 2) The site of lesions were bilateral in 3 cases and unilateral in 11 cases(left in 2 cases, right in 9 cases). The locations were vocal process of arytenoid cartilage in 12 cases(86%), and posterior 1/3 of true vocal cord other than vocal process in 2 cases(14%). 3) Thirteen cases were developed after general anesthesia using endotracheal intubation and 1 case after endotracheal intubation in drug intoxication. Among the 13 cases of general anesthesia, there were 8 cases of Cesarian section delivery. 4) We used the suspension laryngoscope in all cases, high-frequency jet ventilation technique was used for anesthesia in 8 cases and neuroleptic anesthesia in 6 cases. The CO2 laser was used in 5 cases among the jet ventilation technique. There was no complication associated with jet ventilation. CONCLUSION: Jet-ventilation is a useful anesthetic technique in removal of intubation granuloma.
