ABSTRACT
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.
ABSTRACT
Objective To investigate a repair method for unilateral complete cleft lip nasal deformities.Methods Based on the fullness of healthy nasal wing,Z-form plasty was designed with a nasal mucous membrane and alar cartilage flap,to prolong its curtate length of the deformed side through overlapping transposition,and then with suspension of the custom-crafted nasal wing to replace its abnormal structure,subsequently,to recover the normal anatomic structure of the nosewing,and to get the nasal deformity repaired.Results A total of 12 patients with the severe nasal deformity were treated by this method.and all had satisfactory results.Conclusion This technique is a good choice for repairing the severe secondary nasal deformity after single complete cleft lip operation.
ABSTRACT
<p><b>OBJECTIVE</b>To introduce a method of repairing facial tissue defects caused by various factors.</p><p><b>METHODS</b>The reverse narrow pedicle lateral maxillocervical fasciocutaneous flap was designed with its pedicle located in front of auricle. The size of the flaps ranged from 5 cm x 6 cm to 10 cm x 11 cm. The length and width of the pedicle ranged 2 cm-5 cm and 1 cm-1.5 cm.</p><p><b>RESULTS</b>This fasciocutaneous flap was used in 21 cases. All flaps survived except 1 flap showing distal skin necrosis.</p><p><b>CONCLUSION</b>This fasciocutaneous flap didn't include any major blood vessel. The ratio of the pedicle width to flap length broke that of traditional flap and was reverse transfer. The transposition of the narrow pedicle flap was easy. The postoperative appearance (color, texture, cosmetic aspect) was satisfactory. This method was a new design and was ideal for large facial tissue defect repair.</p>
