[Clinical application of pedicel frontal flap in reconstruction of the nasal defects].

Objective: The aim of this study is to explorethe application of improving the design of the myocutaneous flap and the transfer mode in nasal facial defect. Method: Six cases with nasal defects were treated by using lateral or median vascular frontal flap which is nourished by supratrochlear and supraorbital arteries. Three patients with basal cell carcinoma of external nose and three patients with cranial base tumor were hospitalized and underwent surgeries. Result: There were 6 cases in this cohort, with the largest defect being 6.5 cm×3.0 cm and the smallest one being 3.0 cm×2.5 cm in size. Except one patient was missing, the rest of the patients flaps survived, and wounds were healed by first intention. Among 6 patients, 3 patients were treated with lateral forehead flap, 2 patients were treated with median forehead flap, and 1 patient was treated with oblique forehead flap. The follow-up being conducted for 6 months to 12 months, the flaps were normal color and sensation, satisfactory appearance and functional recovery of forehead region. Conclusion: Forearm myocutaneous vessels running more constant, superficial, rich blood supply, easy to dissect and can provide a larger area flap, suitable for different causes of nasal facial defect repair. Large area of flap can be provided. These may be favorable choice for repair of the nasal defects. The tunnel through which the flap was transferred to the defect should be wide enough to avoid flap necrosis because of pedicel flap constriction.
