짧은코변형에서 코외피의 연장방법 : 가로코근걸이 해리와 코경첩 부위 근육융합체의 분리 = Expansion Procedures of the Nasal Envelope in Short Nose Deformity : Release of the Transverse Nasalis Sling and Division of Muscle Confluence in Nasal Hinge Area

다국어 초록 (Multilingual Abstract)

Cartilage extension and nasal envelop expansion play a main role incorrecting short or contracted nose. Despite numerous studies for cartilage expansion, there has been no reports of nasal skin elongation methods. We hereby preport a new method for expansion of nasal envelop with a comprehensive understanding of anatomical structures. From April 2009 to September 2010, 6 patients underwent operations to correct short or contracted nose. Two separating procedures were included for nasal envelop elongation; division of muscle (Procerus, Transverse nasali, Levator labii superior alaque nasi: PTL muscles) confluence located at nasal hinge and release of transverse nasalis sling. To estimate the degree of nasal envelop extension, forced skin traction test was performed. Comprehensive research with fresh cadaver was held to study the relationship between nasal SMAS and surrounding structures. Average 3.8 mm elongation was documented by forced skin traction testafter the procedure. In the fresh cadaver study, transverse nasalis sling and PTL muscle confluence were firmly attached to the supportive framework. From our clinical experience and cadaver study, we discovered that release of transverse nasalis sling and division of PTL muscle confluence are the main factors for nasal envelop expansion in short or contracted nose.
