Primary Ewing sarcoma (ES) arising in the head and neck region is extremely rare, comprising only 1-4% of all cases of ES. ES is much more common in children and white populations,and has a slightly male predominance. About a quarter of patients have detectable metastases at diagnosis. The lung is the most common site for metastases (50%), followed by bone (25%)and bone marrow (20%). We report a case of 27-year-old woman who presented with cervical Ewing sarcoma with lung metastasis and was treated with surgery and chemotherapy.

Background and Objectives : Vocal polyps and nodules are representative chronic benign laryngeal disease. Treatment options for vocal polyp and nodule in general include voice therapy or laryngeal microsurgery. The purpose of this study was to analyze voice results before and after laryngeal microsurgery. Materials and Method: Vocal polyp and vocal nodule patients were treated by laryngeal microsurgery from March 2004 to December 2006 at Kosin University Hospital. All were women. Voice analysis studies were done before and after laryngeal microsurgery. Five measurements were performed: MPT, Fo, jitter, shimmer and NHR. Results: There was significant improvement in the vocal polyp patients regarding MPT, jitter, shimmer and NHR. Also there was significant improvement in the vocal nodule patients regarding MPT, jitter and shimmer. Conclusion: MPT, jitter, shimmer and NHR will be effective acoustic parameters in documenting the quantitative changes in the vocal polyp patients. MPT, jitter and shimmer will be effective acoustic parameters in documenting the quantitative changes in the vocal nodule patients before and after laryngeal microsurgery.

Purpose: Vocal symptoms have been reported after thyroidectomy and even in the absence of injury to the recurrent laryngeal nerve or the external branch of the superior laryngeal nerve. The aim of this prospective study was to evaluate the subjective and objective voice changes in patients without laryngeal nerve injury after thyroidectomy. Methods: The subjects had undergone total thyroidectomy for differentiated thyroid carcinoma from November 2007 to December 2008. Twenty-eight subjects (males: 8, females: 20) were selected for this study. Voice analysis was prospectively evaluated in the subjects at the time of preoperation and postoperation (10.8 months for the males and 11.7 months for the females). A subjective analysis was done using the visual analogue scale (VAS, 0: no symptom, 10: severe symptoms) and objective analyses were determined by several parameters such as the fundamental frequency (Fo), jitter, shimmer and the noise to harmonic ratio (NHR) using the multi-dimensional voice program. Maximum phonation time (MPT)was performed as an aerodynamic test. Results: 3 patients (37.5%) among the males and 14 patients (70%) among the females had subjective postoperative voice change. The VAS showed a significant difference for the females (0 to 1.25±0.97, P<0.001), whereas no changes were shown for the males (0 to 0.88±1.25, P>0.05). The vocal parameters (Fo, jitter, shimmer, NHR) and MPT showed no significant changes for both the males and females (P>0.05). Conclusion: Subjective voice changes may occur after thyroidectomy without laryngeal nerve injury. Surgeons should take possible voice changes into consideration when informing patients before thyroidectomy. (Korean J Endocrine Surg 2011;11:175-178)

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.

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
