The Subunit Approach to Nasal Tip Hemangiomas
Many surgeons who operate on nasal tip hemangiomas find a central vertical scar frustrating. Alternatives such as open rhinoplasty provide great exposure, but the redraping leaves unsightly scars along the alar rim and columella. Therefore, a new aesthetic incision was needed to allow hemangioma reduction in both the horizontal and vertical dimensions while providing adequate access to the lower lateral cartilage for soft-tissue reduction and/or suturing. The subunit incision, based on the pioneering work of Burget and Menick, was developed to provide both excellent exposure and cosmesis. By designing the incision to lie along the contour lines of the nasal subunits, the senior author (B.M.Z.) believed that the border scars would reflect lines of light and cast linear shadows that would mimic the normal ridges and valleys that separate the topographic subunits of the nose. Based on the results of nine recent cases, the authors believe the subunit incision is currently the best approach to correcting nasal tip hemangiomas.
