  • 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.

  • Epiglottic cysts cause stridor mimicking asthma and hinder intubation in surgery. A huge cyst can obstruct the airway, making laryngeal examinations impossible. Before surgery, complete visualization of the larynx is necessary for the successful excision of a cyst. If laryngeal examination fails, computed tomography (CT) scanning can provide detailed information. Virtual endoscopy based on CT data reconstruction can yield a detailed three-dimensional image of the larynx. Here, we report two cases of epiglottic cysts along with virtual endoscopic findings and surgical photographs.

  • Granular cell tumors are relatively uncommon benign laryngeal lesions thought to originate form Schwann cells. The granular cell tumor occurs everywhere in the body, especially in the head and neck. The larynx is relatively an uncommon location, accounting for approximately 3 to $10\%$ of all reported cases. Typically the most common presenting symptom is hoarseness, with some patients also presenting stridor, hemoptysis, dysphagia, and otlagia. But the tumor may be asymptomatic and discovered only incidentally during a routine examination. The diagnosis of granular cell honor can be confirmed by histopathologically and immunocytochemical staining fer S-100 antigen. Treatment of a granular cell tumor consists of a wide local excision by the endoscopic, transoral or laryngofissure methods. Recently, CO2 laser has been used to remove granular cell tumor with clear resection margin. This article describes one such case in a 62-year-old man, followed by a brief review of the literature on this subject.
