  • Title: The staged cheek-to-nose interpolation flap for reconstruction of the nasal alar rim/lobule.
    Author: Fader DJ, Baker SR, Johnson TM.
    Journal: J Am Acad Dermatol; 1997 Oct; 37(4):614-9. PubMed ID: 9344202.
    Abstract:
    BACKGROUND: A deep defect of the nasal alar rim or lobule may represent a unique and difficult challenge because of the lax free margin and structural support supplied by the alar rim and lobule. Traditional closure strategies, including granulation, full thickness skin grafting, or nasolabial transposition flaps may result in unsatisfactory cosmetic and functional outcomes. OBJECTIVE: This article describes our experience with the staged cheek-to-nose interpolation flap for repairing deep skin cancer excision defects of the nasal alar rim and lobule. METHODS: The staged cheek-to-nose interpolation flap was used immediately after Mohs micrographic surgery to repair 18 deep nasal alar rim/lobule defects. In 13 patients, a free cartilage graft was used to restore structural support. RESULTS: The cosmetic and functional outcomes of each repair were judged from good to excellent by patient and surgeon. No cases of infection or flap necrosis occurred. To enhance the cosmetic outcome, three patients underwent spot dermabrasion within 2 months after flap detachment. CONCLUSION: The staged cheek-to-nose interpolation flap, with or without free cartilage grafts, consistently provides good to excellent cosmetic and functional outcomes when performed on properly selected deep nasal alar rim/lobule defects.
