A Case of Pleomorphic Adenoma of the External Auditory Canal / 대한이비인후과학회지

Pleomorphic adenomas mostly occur in major salivary glands. Pleomorphic adenomas arising in the external auditory canal are very rare. The clinical features and natural history of patients with this tumor are obscure. The patients with pleomorphic adenoma of the external auditory canal mostly complain of painless lump, otorrhea, ear fullness and hearing loss. Treatment of choice is a wide excision of tumor to prevent local recurrence. We experienced a case of pleomorphic adenoma in the external auditory canal causing ear fullness and mild otalgia which was treated by local excision via endaural approach. The patient has been free of disease for about 14 months after the treatment. We report the case with a review of literatures.

Treatment of Inverted Papilloma: A Comparision of Extranasal Operation and Conservative Surgery Using Nasal Endoscope / 대한이비인후과학회지

BACKGROUND: Inverted papilloma is a benign neoplastic lesion which shows high recurrence rate and possibility of association with malignancy. Medial maxillectomy has been preferred as a treatment of choice, for conservative treatments resulted in higher recurrence rate. However, introduction of nasal endoscope made more precise evaluation of intranasal lesion under brighter illumination. OBJECTIVES: Aim of this study was to compare the recurence rate between medial maxillectomy and conservative surgery using nasal endoscope. MATERIAL AND METHODS: Thirty one patients who underwent operation between 1980 and 1995 were retrospectively studied. RESULTS: Fifteen patients were treated via external approach and sixteen patients endoscopically. Inverted papilloma was recurred in two cases of endoscopic surgery group and one case of external surgery group. CONCLUSION: Endoscopic conservative surgery can be an alternative surgical modality in the selected cases.
