Reconstruction of Nasal Defects after Skin Cancer Excision by Paramedian Forehead Flap / 대한피부과학회지

BACKGROUND: Repairing large nasal defects in the nose gives us technical challenge. Despite the commonly available surgical techniques, paramedian forehead flap (PFF), an arterial flap, should be considered in repairing some of the large nasal defects. OBJECTIVE: The aim of this study was to evaluate the effectiveness and cosmetic consequences of PFF for the reconstruction of large nasal defects after skin cancer excision. METHODS: Between 2008 and 2011, 8 patients were treated with PFF for reconstruction of large nasal defects after Mohs surgery or wide excision. We reviewed surgical techniques, complications, and final results. Post-operative results were assessed with serial clinical photographs, physicians' objective records and patients' subjective records. RESULTS: The size of surgical defects was ranged from 2.0 to 3.0 cm in their greatest diameter, involving at least 2 cosmetic subunits after tumor excision. Frequent involved sites were nasal tip and nasal dorsum. There were no significant complications, except transient bleeding and oozing. The cosmetic outcomes were considered as good or excellent in most of patients. CONCLUSION: PFF is regarded as the recommended technique for the repair of large nasal defects, involving several cosmetic subunits, providing excellent cosmetic results with few complications.

Nasalis Island Pedicle Flap for Reconstruction of the Nasal Defect / 대한피부과학회지

BACKGROUND: Reconstruction of surgical defects of the nose is often challenging. There are many repair options for a nasal defect, including second-intention healing, primary closure, a skin graft and a skin flap. Among these, the nasalis island pedicle flap is a random pattern advancement flap that has satisfactory vascular supplies from the underlying muscular structure. OBJECTIVE: We wanted to describe the surgical technique of creating a nasalis island pedicle flap and to report on our experience with the postoperative cosmetic outcome. METHODS: Fourteen patients diagnosed with non-malignant melanoma skin cancer on the nose were treated with Mohs micrographic surgery (MMS). The surgical defects were reconstructed with a nasalis island pedicle flap. The size of the tumor and the postoperative surgical defects, the local complications and the cosmetic outcomes were assessed. RESULTS: The size of the primary defects ranged from 0.8 to 2.3 cm at the greatest dimension (with a mean of 1.51 cm). Five cases were located on the nasal ala, three on the nasal dorsum, two on the nasal root, two on the nasal side wall and two on the nasal tip. During the follow-up period, there was no significant postoperative bleeding, necrosis and infection. There was no tumor recurrence and most of the patients showed minimal discernable scarring with satisfactory aesthetic outcomes. CONCLUSION: A nasalis island pedicle flap provided aesthetically pleasing results, and it could be an useful method to reconstruct surgical defects in the nose after MMS.

Various Methods of Reconstruction in Nasal Defect

PURPOSE: Nasal defect can be caused by excision of tumor, trauma, inflammation from foreign body reaction. Nose is located in the middle of face and protruded, reconstruction should be done in harmony with size, shape, color, and textures. We report various methods of nasal reconstruction using local flaps. METHODS: From March 1998 to July 2008, 36 patients were operated to reconstruct the nasal defects. Causes of the nasal defects were tumor(18 cases), trauma(11 cases), inflammation from foreign body reaction(5 cases) and congenital malformation(2 cases). The sites of the defects were ala(22 cases), nasal tip(8 cases) and dorsum(6 cases). The thickness of the defects was skin only(5 cases), dermis and cartilagenous layer(7 cases) and full-thickness(24 cases). According to the sites and thickness of the defects, various local flaps were used. Most of alar defects were covered by nasolabial flaps or bilobed flaps and the majority of dorsal and tip defects were covered by paramedian forehead flaps. Small defects below 0.25cm2 were covered with composite graft or full-thickness skin graft. RESULTS: The follow-up period was 14 months. Partial flap necrosis was observed in a case, and one case of infection was reported, it was improved by wound revision and antibiotics. Nasal reconstruction with various local flaps could provide satisfactory results in terms of color and texture match. CONCLUSION: The important factors of nasal reconstruction are the shape of reconstructed nose, color, and texture. Nasolabial flap is appropriate method for alar or columellar reconstruction and nasolabial island flap is suitable for tip defect. The defect located lateral wall could be reconstructed with bilobed flap for natural color and texture. Skin graft should be considered when the defect could not afford to be covered by adjacent local flap. And entire nasal defect or large defect could be reconstructed by paramedian forehead flap.

A case report of the external nose reconstruction using forehead flap and auricular composite grafts

There are various surgical methods for reconstruction of the nasal defect. Among them, there is some difference in the choosing the proper reconstruction method according to defect size and position. When the defect involved the tip, the columella, and the alar, the local flaps may be preferred, because they can provide sufficient amount of tissue. However, the composite grafts from the ear have been effectively used in reconstructions of smaller sized defects of the columella and ala. We excised total external nose because of squamous cell carcinoma on the nasal tip, columella, and nasal septum. We reconstructed the nasal tip, both alae, and columella with forehead flap. After division of the regional flap, we found partial necrosis of the columella and narrowness of the nostril. So, we used chondrocutaneous auricular composite grafts for reconstruction of the columella and both nostrils. We used the file-folder designed auricular composite graft for reconstruction of columella and the wedge shaped ear helical composite grafts for widening of nostrils. 6 months later, there were no significant problems, except some mismatched dark color in the grafted alar tissues. Here, we report a successful reconstruction of large nasal defect using combined two different reconstructive methods.

Five Cases of Reconstructive Rhinoplasty for Nasal Defects Caused by Neoplasm Resection

The nose plays a significant role in the determination of one's physical appearance as well as various other important functions such as respiration, olfaction, and resonance. It also occupies the most prominent position on the face, a position that makes it vulnerable to distortion by trauma, and incidentally, it is a feature that is most frequently predisposed to skin tumors. The surgical reconstruction for nasal defects caused by the resection of these neoplasms should be considered from two viewpoints : the aesthetic and the functional aspect of the nose. For aesthetic reconstruction of the nose, the tissues for reconstruction should match the surrounding tissue in terms of color and texture. For functional reconstruction, the mucosal layer and the cartilage framework should be reconstructed. We have reconstructed nasal defects in five cases of nasal neoplasms using the forehead flap, full-thickness skin graft, nasolabial flap, buccal mucosal flap, and local flap. We are reporting these cases along with reviews of the relevant references.
