Endoscopic supraglottic laryngectomy by CO₂ laser for selected T1-T3 supraglottic cancer results in improved postoperative function and decreased morbidity, with comparable survival to open surgery. The aim of this study was to retrospectively evaluate oncologic and functional outcomes after transoral CO₂ laser surgery for supraglottic cancers. Subjects and Method:Nineteen patients (Fresh group:13 patients, Radiotherapy failure group:6 patients) who were diagnosed as supraglottic cancer and treated with CO₂ laser surgery between December, 1999 and September, 2006 were evaluated. All the patients were followed-up more than 12 months. Eleven patients in the Fresh group underwent neck dissection. Results:Ultimate local control rate was 100% for both Fresh group and RT failure group. Survival rates of 3-year and 5-year for the Fresh group and the RT failure group were 100% and 68.6%, and 75% and 50%, respectively. There were no significant postoperative complications. Conclusion : Although our experience with supraglottic cancers treated by transoral CO₂ laser surgery is still too limited to confirm the definite oncologic and functional results, transoral CO₂ laser surgery seems to be a safe and reasonable tool, and a time and cost-effective alternative to

Small cell carcinoma is primarily a lung malignancy occurring rarely in extra pulmonary sites such as the larynx, nasal cavity, paranasal sinuses, and oral cavity. The diagnosis was based on histological investigation expanded with immunohistochemical tests of a fragment of a tissue. The immunohistochemical stain was positive for synaptophysin, CD56 and cytokeratin. So we diagnosed small cell carcinoma. The treatment of small cell carcinoma diagnosis differed from the treatment of other neuroendocrine carcinomas and squamous cell carcinomas of the larynx. We report a case of 72-year-old man with a rare case of small cell carcinoma in the supraglottic region and a brief review of literature. Korean J Otorhinolaryngol-Head Neck Surg 2010;53:784-6

Chondroid syringoma, or mixed tumor of the skin, is a benign neoplasm of sweat gland origin that occurs most frequently in the head and neck. The most common sites are the nose, cheek, upper lip, scalp, forehead, and chin. The tumor typically presents as a slowly growing, painless intradermal or subcutaneous nodule in patients between the ages of 20 and 60 years. In the head and neck it occurs twice as commonly in males as in females, but no predilection for sex is observed when it develops at other sites because of a rare possibility of malignant transformation. Total surgical excision remains the best therapeutic option to avoid tumor recurrence and close follow-up observation is recommended. We report a very rare case of chondroid syringoma accompanied by cholesteatoma in a 49-year-old man who presented as a external auditory canal mass with a brief review of literatures.

Eosinophilic otitis media (EOM) is a newly recognized intractable middle ear disease, characterised by the accumulation of eosinophils in middle ear effusion and middle ear mucosa. Since EOM patients show gradual or sudden deterioration of hearing, it is important to properly diagnose EOM and to start adequate treatment for EOM. We experienced a case of EOM, so discuss the clinical features, pathogenesis, and management of EOM. EOM is often complicated by rhinosinusitis (eosinophilic sinusitis). High-tone loss is more frequently found and more severe in EOM patients than in chronic otitis media control patients, and EOM patients sometimes become deaf suddenly. Systemic or topical steroid administration is the most effective treatment for patients with EOM. The instillation of prednisolone, a suspension of steroids, into the middle ear is very effective for controlling eosinophilic inflammation in our case. It is very important to explain to patients with EOM that the disease may last for a long period and that progressive and sudden hearing loss may occur.
