ABSTRACT
Objective@#To investigate the recontruction of facial aesthetic subunit with kite flap after resection of benign tumor at supraorbital ridge.@*Methods@#From June 2012 to September 2015, 12 cases(8 male and 4 female, aged 34-68 years) with benign tumor at supraorbital ridge underwent tumor resection, following by reconstruction with kite flap. The tumor size ranged from 0.3 cm×1.0 cm to 0.5 cm× 1.0 cm, and the defects size ranged from 0.5 cm× 1.2 cm to 0.8 cm×1.2 cm. The kite flaps were 0.6 cm×1.2 cm to 1.0 cm×1.5 cm.@*Results@#All the 12 flaps survived completely with primary healing and no complication. The scar was inconspicious, which was hidden into brows. The brows showed good symmetric cosmetic effect.@*Conclusions@#The kite flap has reliable blood supply and survival rate, which does not affect the brows symmetry. Aesthetic result can be achieved by Kite flap in the reconstruction of defect after resection of benign tumor at supraorbital ridge.
ABSTRACT
Objective To study the feasibility of trans-supraorbital keyhole approach microsurgery for sellar tumors.Methods The operation was conducted under combined intravenous general anesthesia and the patient was maintained at a dorsal position.A skin incision was made along the lateral eyebrow at 3.5~4.0 cm in length.The frontal muscle periosteous flap was draged upwards and the orbicularis muscle periosteous flap was dragged downwards.Then the tempotal muscle was dragged laterally.The position of the keyhole was located behind the temporal line.By using a milling cutter,a bone window 2 cm ? 3 cm in size was made medially.The inner margin of the supraorbital skull was shaped to expand the visual field of microsurgery.The cerebral dura mate was opened curvily,with the base directing to the orbital margin.The frontal lobe was elevated gently and the cerebrospinal fluid was drained.The tumor was fully exposed and resected.Results Total resection of tumor was achieved in 22 cases,and part of posterior tumor membrane remained in 2 cases of craniopharyngioma.Hypoadrenocorticism occurred in 1 case of ACTH adenoma after operation and a hormone replacement therapy was required. Temporary postoperative diabetes insipidus occurred in 8 cases and was relieved after 1 week.The postoperative urinary volume decreased significantly in 9 cases of preoperative diabetes insipidus.Visual disorder on the operational side was aggravated after operation in 1 case of tuberculum sellae meningioma,and was gradually improved after 1 week.No recurrence was observed under MRI examination in 18 cases at 3 months after operation.Conclusions Trans-supraorbital keyhole approach microsurgery is feasible,and it gives minimal operational trauma,thorough resection of tumor,and good cosmetic outcomes.
