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.

A Case of Trichofolliculoma in the Nasal Vestibule / 대한이비인후과학회지

Trichofolliculoma is a rare skin lesion. It is an adnexal tumor of hair follicles, which was first described by Miescher. Trichofolliculoma is a hamartomatous lesion of hair follicle origin, intermediate in differentiation between a hair follicle nevus and trichoepithelioma as classified by Kligman and Pinkus. It usually manifests clinically as a small, slowly growing, well-demarcated, flesh-colored papule on head and neck. The diagnosis is difficult clinically and is based mainly on histopatholigic appearance. It is commonly misdiagnosed as sebaceous cyst, nevus, and basal cell carcinoma. Treatment is by simple excision and recurrence is rare. We report a case of trichofolliculoma of nasal vestibule with a review of literature.

Verruca Vulgaris of the Larynx: A Case Report / 대한이비인후과학회지

Verruca vulgaris is commonly seen on skin, but extremely rare in other areas, especially in larynx, where it could be not uncommonly misdiagnosed as verrucous carcinoma. In the recent studies, we noted that verruca vulgaris of the larynx is related to human papilloma virus type 6, 11, which is different from human papilloma virus type 2, 4, which is found on skin. Verruca vulgaris of the larynx occurs in old age with the average of 56 years, and it looks white in color on laryngoscopic examination, which is limited to the true vocal cords. It recurs infrequently. Pathologically, it is heavily keratinized and it contains prominent keratohyaline granules and exhibits koilocytosis. We experienced a case of verruca vulgaris of the larynx in a patient with hoarseness lasted for 3 months. So we report this case with a review of literature.
