RESUMO
Objective@#To investigate the feasibility and technical tips of repairing facial defects with pre-expanded propeller flap based on the perforators of the supratrochlear artery or the supraorbital artery.@*Methods@#In the first-stage operation, a tissue expander was buried underneath the frontalis muscle. The second-stage operation was conducted using pre-expanded supratrochlear artery or the supraorbital artery based propeller flap to repair facial defect.@*Results@#From July 2010 to July 2016, this method was used in 8 patients. 5 flaps were based on the supratrochlear artery, and 3 flaps based on the supraorbital artery. Expander size was ranged from 150 ml to 300 ml. The size of propeller flaps was from 10 cm × 6 cm to 15 cm × 13 cm. All the flaps survived without any major complications. Follow-up period ranged from 3 to 36 months. Eyebrow replacement, flap thinning and scar revision were performed in 6 cases. All patients were satisfied with the final aesthetic result.@*Conclusions@#The pre-expanded propeller flap based on the supratrochlear artery or the supraorbital artery is an alternative option to repair the facial defect in appropriate cases.
RESUMO
Objective To explore the design of forehead flap pedicled with supratrochlear artery and shift way for aesthetic reconstruction of the nose without secondary operations for debulking.Methods Origin of blood supplies and the distributed situation of the vessel in the frontal region were studied through the internal carotid artery and the external carotid artery X-ray angiography.The frontal region existed polyphyletic blood supplies,the supratrochlear artery and the supraorbital artery set out many branches,respectively,in the level of frontal bone eyebrow plane.One constant,thicker horizontal branch from the superficial temporal artery obviously extended to the forehead median.The branches from three blood vessels mentioned above constituted the network of artery adequate in the muscle and the subcutaneous tissue level,assumed the three-dimensional distribution in the forchead region.The nasal reconstruction had been done for 9 patients with the oblique orientation designed forehead flap by using one side of supratrochlear artery as the pedicle and cutting skin paddle with the same or the opposite side of forehead flap.Results All flap survived completely with the restoration of nasal shape and functional satisfaction.Conclusion The forehead oblique orientation flap pedicled with one side supratrochlear artery is nourished by the rich blood supply.The flap can be split into two flaps:a myofascial flap and a skin flap in far part.Myofascial flap may be the good package of cartilage framework,and simultaneously split skin flap is favorable of the shape models.The flap may satisfy the demand of the nasal restoration.
