Sarcomatoid carcinoma is a rare type of head and neck cancer that presents both epithelial squamous cell carcinoma and sarcomatous features. There is much debate on pathogenesis, clinical behavior, therapeutic options and prognostic factors for this tumor. Treatment is similar for squamous cell carcinoma with respect to the state, location and size of the tumor. We report a case of sarcomatoid carcinoma on larynx, which was treated by surgical excision and postoperative radiotherapy. The relevant literature is briefly reviewed.

Background and objectives:Recently, endoscopic sinus surgery (ESS) is commonly performed to treat the sphenoid sinus disease. Identification of the natural ostium of sphenoid sinus (SS) according to surgeon’s operating view play an important role in endoscopic sphenoid approach. This study is undertaken to investigate the role of superior turbinate (ST) as an anatomic landmark of natural ostium of SS in endoscopic sphenoidotomy. Materials and Methods:Medical records and computed tomography (CT) images of 77 patients from March 2006 to December 2007 who underwent ESS were analyzed. We tried to investigate the location and distance of the natural ostium on the superior turbinate, skull base and nasal septum. We also measured the anterior wall thickness of the SS by using CT images. Results:The natural ostium of the SS was located on the medial side of the ST in all patients who underwent endoscopic sphenoidotomy (45 cases). The level of posteroinferior end of the ST corresponded to the inferior portion of anterior wall of the SS. The lateral portion thickness of the anterior wall of the SS was thinner than the medial portion (77 cases). Conclusion:During an endoscopic sphenoidotomy, the superior turbinate is an important anatomic landmark for identifying the natural ostium of the SS. When widening the anterior wall of SS is performed, we sug-gest that the procedure should be directed to the lateral 1/3 portion, considering the thickness of anterior wall of SS.

This study aims at providing some basic information to develops an teaching model of creative dance through theme, as analyzing the students` reaction shown in each ones, and looking into not only the effects of creative dancing, but possibility of it`s application in our situation. Working with the students of the dancing team in the first grade, Chungbuk High School of Art, the results from the end of 14 times` experiments are mentioned below : 1. The change of conception on creative dance through learning of problem solving. As the results of performance with theme, creative dance through learning of problem soving is so effective that the students` conception of it changes into positive one though it was at first thought to be reluctant before class. 2. The evaluation of class In self-enveluating two theme. 「Did you make movements in a dignified manner without shame?」 and 「Did you use the body as much as you can?」, it shows that physical theme is more difficult for them than image theme, meaning that the evaluation of curriculum activation depends on contents rather than it`s procedures. 3. The analysis of themes (1) Themes impressive to the students The theme that students like and feel easy to do is imasinable one, and physical themes are shown as difficult to follow. (2) The analysis of each theme ①「Creative dance of using newspapers」 comes out as the one that is effective, free from arty formation. ② Hard and difficalt for them are movement theme such as 「running jump-turn」 and 「twist-turn-?」 which need a great deal of exercise and require high-level technique to link each movement. ③ Next gestures followed by the movement theme of 「twist-turn-?」 are jump, game, balance, rolling and kick in order. ④ 「Gaze in a groups」 is effective to make expression wider. ⑤ It`s the. theme 「Oh!. I`m in trouble.」 that helps easily to accept. the nature of it. ⑥ In watching VTR, they reflect themselves as compared with others and get opportunity to have confidence or satisfaction in creative activities. ⑦ 「Extension-contraction」 is considered as a tough theme due to the limitations of expression. ⑧ 「Group-creations」 awakes importance of cooperation and brings confidence to them. (3) General conclusion The themes given to the students have developed creative ability through experiences of creating, dancing, watching, atc, and brought them into confidence, satisfaction, and possibility, so that the education model we have studied can be applied in our field.

Background and Objectives:Closed reduction has been a primary treatment procedure for nasal bone fracture, but the post-operative results have not always been satisfactory. We compared the satisfaction rate of closed reduction with that of open septorhinoplasty for the treatment of nasal bone fracture and evaluated the effectiveness of open septorhinoplasty for the primary treatment of nasal bone fracture. Materials and Method:We performed a retrospective review of patients who underwent a closed reduction treatment for nasal bone fracture from March 2004 to February 2006 and conducted telephone surveys to monitor their post-operative cosmetic and functional problems. We estimated the factors that were involved in the low satisfaction rate and determined the indications of open septorhinoplasty. Prospectively, the patients who underwent open septorhinoplasty from September 2006 to August 2007 were interviewed for their cosmetic and functional satisfaction rate. Results:Forty percent of the patients who underwent closed reduction had cosmetic concerns and twenty percent had functional concerns. The factors involved in the low satisfaction rate were septal fracture, associated fractures, and multiple fragmentation. Eight percent of the patients who underwent open septorhinoplasty had cosmetic concerns and other eight percent had functional concerns. Conclusion:A careful pre-operative evaluation of the type of fracture is important for the treatment of nasal bone fracture. Also, when nasal bone fracture is combined with septal fracture, associated fracture or unilateral fragmentation, open septorhinoplasty has to be considered to reduce secondary deformities and to improve the satisfaction rate of the patients.

Tympanic membrane perforations are usually caused by trauma, infection, surgical procedures such as tympanoplasty or myringoplasty. Because perforations interfere with the transmission and perception of sound, whatever the cause of the perforation, repair of the membrane is desirable. The purpose of this study is to investigate the clinical application and usefulness of allograft amniotic membrane, instead of autograft materials, in the management of tympanic membrane perforation. Subjects and Method:A retrospective study was performed on 14 patients who underwent myringoplasty with allograft amniotic membrane for tympanic membrane perforation from October 2006 to September 2007. Information was collected on sex, age, the cause of perforation, the perforation size, postoperative hearing result, the success rate. Results:Of 14 patients, 13 patients were successfully treated by myringoplasty with allograft amniotic membrane and one patient failed due to infection. So the overall success rate was 93%. The mean air-bone gap was improved from 13.3 dB to 7.1 dB. Conclusion:The myringoplasty with allograft amniotic membrane is a successful procedure for the healing of tympanic membrane perforations.

Schwannoma, also referred to as neurilemmoma, is an encapsulated benign soft tissue tumor arising from the schwann cells of the nerve sheath. Although 25 to 45% of schwannomas arise in the head and neck region, pterygopalatine fossa is the rarest sites of involvement with only 23 cases reported in the medical literature. It is usually seen in the second and fifth decades, but sex or racial predilection has not been noted. Clinical features of this tumor are dependent on the involved anatomical site, nerve of origin, and compression of adjacent structures. The differential diagnosis of masses in pterygopalatine fossa includes angiofibroma, fibrous histiocytoma, malignant melanoma, lymphoma, and low-grade rhabdomyosarcoma. The treatment of choice is that the tumor is completely removed with careful preservation of its nerve. Recently, the authors experienced a case of schwannoma arising in pterygopalatine fossa, which was removed with transantral approach. Hence, we report a rare case with a review of literature.

Background and Objectives:With the availability of more sensitive ultrasonography, a larger number of nonpalpable thyroid d nodule. The purpose of this study is to investigate the clinical significance of thyroid incidentaloma and the usefulnes of the USG-FNA in the management of thyroid incidentaloma. Subjects and Method:A retrospective study was performed on 208 pa-tients who underwent USG-FNA for thyroid incidentaloma smaller than 1.5 cm from 2001 to 2005. The cytologic findings were compared with the ultrasonographic findings and the surgical pathology. Results:Suspicious malignant sonographic findings cytologicaly diagnosed as benign lesion (76.4%), 7 cases as follicular neoplasm (3.3%), 33 cases as malignancy (15.8%), and 9 cases as inadequate specimen (4.4%). Of the 40 cases with folicular neoplasm and malignant cytology, 37 cases underwent sur-gery and 30 cases were confirmed to malignancy on the postoperative pathologic diagnosis. In the cases diagnosed to malig-nancy on pathology, extracapsular extension was present in 9 cases (30% ) (26.7%). The sensitivity, specificity, and accuracy of the USG-FNA for malignancy were 93.3%, 71.4%, and 89.1%, respectively. Conclusion:USG-FNA is a useful diagnostic tol in the management of thyroid incidentaloma especially when more than two suspicious malig-nant sonographic findings need to be detected. The clinical characteristics is not significantly diferent between palpable and nonpalpable nodules. (Korean J Otorhinolaryngol-Head Neck Surg 2007 ;50 :622-6)
