Abstract:
The alar cartilage malposition is defined as any displacement of lateral crura from the usual parallel alignment with nostril rims. It has several characteristics including parentheses deformity, notches in alar rims, flat nasal tip, square basal perimeter. It tends to be misdiagnosed as cartilaginous hump or bulbous tip because of its longitudinally prominent lobule. But, exact diagnosis can be easily attained with careful examination and recognition in the clinical diagnosis of bulbous or ambiguous tips. It is confirmed by the resistless collapse of lateral alar rim when light compression is applied by cotton stick. Its incorrect diagnosis can bring about inappropriate tip graft, soft tissue resection, rasping, humpectomy and secondary nasal deformity may develope as a result. Authors performed open approach followed by meticulous dissection of displaced alar cartilages. Each medial portion, corresponding to the cephalic portion of normal lateral crus, was resected. Then, each lateral crus was symmetrically rotated in the infero-lateral direction along the axis of the medial crura. If needed, autocartilage on-lay graft and dorsal augmentation were done for optimal aesthetic result. We believe accurate evaluation of the anatomical variation should be checked out preoperatively and recommend out method for the effective correction of unusual bulbous or broad tips.
