ABSTRACT
Objective To assess the harvest method and application value of free-style anterolateral thigh perforator flap (ALTPF) in oral-maxillofacial reconstruction.Methods Fifty-three patients who suffered from oral and maxillofacial tumor underwent simultaneous reconstruction using free-style ALTPFs after radical resection from August,2013 to May,2014.Perforators of the ALTPF region were marked through hand-held Doppler probe preoperatively.Flaps were designed centered on perforators according to the defect size of the accepting site.Incisions were first made at the inner border of the designed flap.Perforators were exposed above the fascia lata femoris and then dissected retrogradely through the vastus lateralis muscle to harvest a vascular pedicle with desired caliber and length.Flap thinning was applied under microscope in some cases to compromise the need of the accepting site.Results All 53 flaps survived after transplantation while skin exfoliation occurred in 5 cases due to flap thinning.Four cases sustained partial necrosis and was cured by trimming and dressing changes.Five to 14 months' post-operative followup showed satisfactory accepting-site morphology with good speech function and swallowing recovery.All donor sites were closed primarily without skin-grafting,leaving no donor-site complications including incision disruption,scar hyperplasia and muscle strength degeneration of the lower limb.Conclusion Multiple perforators have been accu rately located preoperatively in free-style harvest approach of ALTPFs,thus optimal effects can be reached with decreased donor-site morbidity and improved aesthetic outcome to the uttermost,which accords with the refined,personalized and minimal invasive development concept of modem reconstructive surgery.
ABSTRACT
Objective To explore the treatment and efficiency of high blood flow vascular malformations of oral maxillofacial region with super-selective arterial embolization. Methods 18 cases underwent angiography of the head and neck before treatment and then followed by super-selective catheterization with microcatheter to embolize the feeding vessels of the vascular malformations with PVA. 8 cases underwent surgical excision within 72 hours after the embolization and the other 10 cases passed through the arterial radical emboliztion treatment. Results Technical success ratio reached 100% with no complications causing skin necrosis or incorrect arterial embolization else where in the skull. All 8 cases undergone preoperative embolization showed obviously less bleeding, easier removal of the mass and reduction of operation time. 10 cases with radical arterial embolization manifested reduction of swelling and improvement of organ function within 1 to 24 months after the procedure. 5 patients were cured with only once operation, 4 cases with twice operation and 1 with the thrice. Conclusions Aterial embolization is a safe and effective method in the treatment of high blood flow vascular malformations of oral maxillofacial region.
