研究室紹介
Professor Kyung Sung Ahn's research lab specializes in head and neck surgical disorders, with a strong focus on temporal bone pathology, facial nerve disorders, and deep neck infections. The lab investigates the radiological and surgical aspects of conditions such as facial nerve paralysis, cholesteatoma-induced automastoidectomy, vascular anomalies in the middle ear, and the management of deep neck space infections. Their work emphasizes accurate diagnosis through advanced imaging techniques like dynamic temporal bone CT and correlates clinical outcomes with surgical interventions. The lab's research contributes significantly to improving diagnostic precision and patient safety in otolaryngological surgery.

5Background and Objectives：Since Sir Charles Bell (1829 demonstrated that motor innervation of the muscles of facial expression is by cranial nerve Ⅶ, many more research have contributed to the diagnosis and treatment of facial nerve paralysis. We attempted to evaluate the causes, arrive at accurate diagnosis and determine the treatment for facial nerve paralysis. Materials and Methods：The authors analyzed 65 cases of facial nerve paralysis diagnosed at the Department of Otolaryngology, Hanyang U
Background and Objectives: To describe the CT findings of automastoidectomy caused by cholesteatoma, and to evaluate the natural course of cholesteatoma by comparing it with the postmastoidectomy defect of the temporal bone. Materials and Methods: We retrospectively reviewed the CT findings of 21 cases of automastoidectomy in 17 patients with cholesteatoma and of 19 cases of postmastoidectomy in 16 patients. Results: 1) In automastoidectomy, the posterior walls of bony defects of the temporal bo
Vascular masses in middle ear space are uncommon, and include high dehiscent jugular bulb or a glomus tumor occurring most frequently. The bone over the carotid artery may be dehiscent, resulting in the appearance of a vascular mass in the anteroinferior quadrant as it passes in its usual course through the middle ear. Less frequently, internal carotid artery courses aberrantly within middle ear space. If aberrant carotid artery was misdiagnosed, surgical intervention can lead to massive bleedin
Deep neck infections affecting soft tissue and fascial compartment of head and neck, have decreased after development of chemotherapeutic agents and antibiotics. But these infections may still remain in high motality and morbidity. The authors have studied 50 cases of deep neck infection experienced at Hanyang University Hospital during recent 5 years and the following results were obtained. The age of onset was from 15 months to 67 years old, average 31 years old, and 28 cases(56%) were male, a
