ABSTRACT
BACKGROUND:
Many head and neck surgeons preferred the radiotherapy as a first choice in treating early laryngeal carcinoma(T1, T2) to surgical operation because of the relatively high curability(80-90%), organ preservation and better quality of life. If radiotherapy failed, some surgeons perform total laryngectomy as salvage operation, but others prefer to perform partial laryngectomy, which is increasing in tendency.OBJECTIVE:
To investigate the pattern of cancer invasion to the laryngeal cartilages using salvage laryngectomized cancer specimens which had recurred after radiotherapy. MATERIALS &METHOD:
Preoperative computerized tomograpy images were retrospectively compared to postoperative salvage laryngectomized cancer specimens which had recurred after radiotherapy 13 cases from March, 1985 to February, 1994.RESULTS:
1) In laryngeal cacer recurred after radiotherapy, incidence of cartilage invasion was not in early supragolttic cancer. but all in advanced supraglottic cancer, and 3cases of 5 cases(60.0%) in early glottic cancer, 4cases of 5 cases(80.0%) in advanced glottic cancer. 2) The order of laryngeal cartilage invasion was the first thyroid cartilage(61.5%), the second arytenoid cartilage(30.7%), and the third cricoid cartilage(23.1%). 3) The diagnostic accuracy of preoperative CT scan for laryngeal cartilage invasion was 66.7% in thyroid cartilage, 55.6% in arytenoid cartilage, 55.6% in cricoid cartilage, and 100% in epiglottis.CONCLUSION:
Selection of partial laryngectomy as salvage operation should be considered carefully.
