Objectives: Calcification of the thyroid nodule has been reported to have a close relationship with differentiated thyroid carcinoma, however there are limited studies on the relationship between the calcified thyroid nodule and thyroid malignancy. The authors studied the clinical significance of calcification within the thyroid nodule. Materials and Methods: There were total of 60 patients who underwent surgery for calcified thyroid nodules which were identified from plain neck X-ray, ultrasound and computed tomography during the period January 1991 to June 1996 at the Department of Otorhinolaryngology-Head and Neck Surgery of Korea University Hospital. Six patients were not included because of recurrence and previous thyroid surgery. Histopathologic and radiologic analysis was done on the remaining 54 patients. Results: Results showed that 25 of 54 cases(46%) to be malignant histopathologically. Of the 25 malignant cases, papillary carcinoma was the most common with 22 cases followed by 2 cases of undifferentiated carcinoma and I case of medullary carcinoma. Statistically high incidence of malignancy was observed when the consistency of calcified thyroid nodule was solid, shape of calcification was irregular and inhomogenous, and adhesion of calcified thyroid nodule to the regional structure was present. Conclusion: The probability that a thyroid nodule is malignant has been reported to be 320%. However, about half of the thyroid nodules with calcification found to be malignant on this study, calcification of the thyroid nodule can be used as a guideline for detecting thyroid malignancy.

Background and Objectives : The treatment of supraglottic stenosis remains a challenging problem in the field of otolaryngology due to its association with dyspnea, dysphagia, and frequent recurrence. Any satisfactory treatment is not yet known. The author experienced six cases of supraglottic stenosis and report the successful treatment of five cases by repeated endoscopic laryngeal excision with KTP-532 laser under suspension layngoscopy. Materials and Methods : Six adults who were treated for supraglottic stenosis between March 1994 and December 1998 at the Department of Otoloaryngology-Head and Neck Surgery, Korea University Medical Center were studied retrospectively. The patients were placed under general anesthesia followed by endoscopic laryngeal excision with KTP-532 laser under supension laryngoscopy. The scar tissue and granulation tissue were visualized with an operating microscope, and then removed using KTP-532 laser (15watts, continuous mode). Intraoperative local steroid(Triamcinolone ) was injected in all cases after the stenotic portions were removed. Results : Endoscopic excision was performed in five cases ; among the five cases, cricoid cartilage was concomitantly removed in two cases, and epiglottis was removed in one case. Satisfactory swallowing and airway respiration were possible in all five patients who underwent endoscopic widening. Conclusion : The treatment of supraglottic stenosis is different from that of tracheal or glottic stenosis in that supraglottic stenosis is mainly developed in membraneous form. Repeated laser excision and local steroid injection under suspension laryngoscopy is an effective and recommend able method for the treatment of supraglottic stenosis.
