Primary Angiosarcoma of the Parotid Gland / 대한이비인후과학회지

Angiosarcoma is an exceedingly rare and highly malignant neoplasm which develops from the endothelium of blood vessels. Only a few cases of primary angiosarcoma of the non-irradiated parotid gland have been reported. In this case, we report a primary angiosarcoma of the parotid gland in a 64-year-old man without prior irradiation of the head and neck region. MRI finding revealed a 3.9x2.7 cm sized mass located in the right parotid gland with unhomogenous enhancement in T2 weighted image. The patient underwent a total parotidectomy and radical neck dissection. The histologic diagnosis was high-grade angiosarcoma showing pleomorphic spindle or epithelioid tumor cells growing as solid infiltrative pattern or slit-like irregular vascular lumina formation. Despite postoperative radiation therapy, the patient died of lung metastasis with hemorrhage 3 months later.

Comparative Values of External Nose Measurement with Photograph According to Sex and Age in Korean Adults

BACKGROUND AND OBJECTIVES: Rhinoplasty has been frequently performed for correction of injured nose or cosmetic reasons. Korean standard values are insufficient, and most reference values are based on Caucasian ones. We measured Korean values of external nose with photographs according to sex and age. MATERIALS AND METHODS: Three hundred forty seven subjects without past history of operation or trauma were included in this study. With scaled instrument for head fixation, frontal and profile views were taken. On frontal view, physiognomic face height and nasal width were measured. On profile view, midface height, nasal height, alar height, glabellar depth, nasion depth, nasal dorsum depth, nasal tip depth, nasal depth, nasofrontal angle and nasolabial angle were measured. And location of nasion and shape of nasal dorsum were also classified. RESULT: Physiognomic face height decreased with age in both men and women groups. Nasofrontal angle increased with age in men. Nasion was located between upper end of upper eyelid and lateral canthus in most cases. On classifying the shape of nasal dorsum, straight type was the most in both men and women groups. CONCLUSION: We could know average measurements of external nose and differences of those according to sex and age in Korean adults. And it is thought that these data will be useful to facial plastic surgery including rhinoplasty.

Endoscopic Guided Power-Assisted Adenoidectomy Using Proper Combination of Endoscope and Microdebrider ; 6 Years of Surgical Experience / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Because of its advantage over the conventional method, power-assisted adenoidectomy has become an increasingly popular procedure in adenoidectomy. The purpose of this paper is to find the best combination of endoscope and microdebrider to achieve the most successful outcome in patients with various configuration of adenoid vegetation. SUBJECTS AND METHOD: One hundred ninety-one patients who underwent adenoidectomy in the department of Otolaryngology at Inje University Seoul Paik Hospital from January 2000 to February 2006 were reviewed by charts and recorded video tapes for the techniques that we applied to these patients. RESULTS: Four different combinations can be created from two different angles of endoscope and microdebrider ; transnasal 0degrees endoscopic guided transnasal adenoidectomy using straight microdebrider (TNTN), transnasal 0degrees endoscopic guided transoral adenoidectomy using curved microdebrider (TNTO), transoral 70degrees endoscopic guided transnasal adenoidectomy using straight microdebrider (TOTN) and transoral 70degrees endoscopic guided transoral adenoidectomy using curved microdebrider (TOTO). TOTO was the most frequent combination for simple adenoid vegetation. However, it is not suitable for removal of adenoid located high in the pharyngeal roof. In this case, we added TNTO to TOTO. The least frequent combined technique was TNTN, which has inherent limitation to use in small sized nares and younger age. In this situation, TOTN is a better alternative to use. CONCLUSION: From six years of experience, we confirmed that endoscopic guided powerassisted adenoidectomy should be performed with proper combination of endoscope and microdebrider based on the location and configuration of adenoid vegetation. The most ideal combination we consistently applied for removal of adenoid is as follows ; first, TNTO, secondly, TOTO. Lastly, TOTN could be useful in selected cases.
