From August of 1995 through July of 1998, 38 free anterolateral thigh flaps were transferred to reconstruct soft-tissue defects. The overall success rate was 97 percent. Among 38 anterolateral thigh flaps, four were elevated as cutaneous flaps based on the septocutaneous perforators. The other 34 were harvested as myocutaneous flaps including a cuff of vastus lateralis muscle (15 to 40 cm3), either because of bulk requirements (33 cases) or because of the absence of a septocutaneous perforator (one case). However, vastus lateralis muscle is the largest compartment of the quadriceps, which is the prime extensor of the knee. Losing a portion of the vastus lateralis muscle may affect knee stability. Objective functional assessments of the donor sites were performed at least 6 months postoperatively in 20 patients who had a cuff of vastus lateralis muscle incorporated as part of the myocutaneous flap; assessments were made using a kinetic communicator machine. The isometric power test of the ratios of quadriceps muscle at 30 and 60 degrees of flexion between donor and normal thighs revealed no significant difference (p > 0.05). The isokinetic peak torque ratio of the quadriceps and hamstring muscles, including concentric and eccentric contraction tests, showed no significant difference (p > 0.05), except the concentric contraction test of the quadriceps muscle, which revealed mild weakness of the donor thigh (p < 0.05). In summary, the functional impairment of the donor thighs was minimal after free anterolateral thigh myocutaneous flap transfer.
From August 1995 to June 1999, 140 free anterolateral thigh (ALT) flaps were transferred to reconstruct a variety of soft-tissue defects. The size of ALT flap ranged from 10 to 33 cm in length and 4 to 14 cm in width. Based on the anatomic variations of the perforators, the blood supply to the skin island came from the septocutaneous perforators only in 19 patients (13.6%), arising from the descending or transverse branch of the lateral circumflex femoral artery (LCFA), or originating directly from LCFA. The other flaps were supplied by musculocutaneous perforators that were elevated as a true perforator flap via intramuscular dissection (N = 34, 24.3%), or used a cuff of vastus lateralis muscle for added bulk (N = 87, 62.1%). The overall success rate was 92% (129 of 140). After a 2-year follow-up, all flaps have healed unevenffully and donor thigh morbidity is minimal. Anatomic variations must be considered if the ALT flap is to be used safely and reliably.
Thirteen patients with large ameloblastomas of the mandible underwent segmental mandibulectomy and immediate reconstruction, with simultaneous placement of osseointegrated implants. All patients received palatal mucosal grafts around the dental implants 6 to 10 months after surgical treatment and received implant-supported prostheses another 1 to 2 months later. There were five female and eight male patients, with a mean age of 32 years (range, 17 to 50 years). The mean length of the mandibular defect was 8.8 cm (range, 5 to 13 cm). All free fibula flap procedures were successful, with no reexplorations or partial flap losses. There was no clinical or radiographic evidence of failure during the osseointegration process for any implant. With functional occlusal loading, the marginal bone loss around the implants was less than 1.5 mm in a mean follow-up period of 40 months (range, 18 to 70 months). There were no recurrences during that time. The technique described allows improved access to the bone at the time of reconstruction, immediate assessment of alveolar ridge relationships, and accurate fixation of the implant-fibula construct. The advantages of this procedure include a reduced risk of recurrence with segmental resection, reliable mandibular reconstruction, and reduction of the number of surgical procedures, allowing full oral rehabilitation in a shorter time. It is concluded that segmental mandibulectomy and immediate vascularized fibula osteoseptocutaneous flap reconstruction, with simultaneous placement of osseointegrated implants, represent an ideal treatment method for large ameloblastomas of the mandible.
Large, full-thickness lip defects after head and neck surgery continue to be a challenge for reconstructive surgeons. The reconstructive aims are to restore the oral lining, the external cheek, oral competence, and function (i.e., articulation, speech, and mastication). The authors' refinement of the composite radial forearm-palmaris longus free flap technique meets these criteria and allows a functional reconstruction of extensive lip and cheek defects in one stage. A composite radial forearm flap including the palmaris longus tendon was designed. The skin flap for the reconstruction of the intraoral lining and the skin defect was folded over the palmaris longus tendon. Both ends of the vascularized tendon were laid through the bilateral modiolus and anchored with adequate tension to the intact orbicularis muscle of the upper lip. This procedure was used in 12 patients. Six patients had cancer of the lower lip, five patients had a buccal cancer involving the lip, and one patient had a primary gum cancer that extended to the lower lip. Total to near-total resection (more than 80 percent) of the lower lip was indicated in six patients. In two other patients, the cancer ablation included more than 80 percent of the lower lip and up to 40 percent of the upper lip. A radial forearm palmaris longus free flap was used in all cases for reconstruction of the defect. Free flap survival was 100 percent. At the time of final evaluation, which was 1 year after the operation, all patients had good oral continence at rest (static suspension) and had achieved sufficient oral competence when eating. Ten patients were able to resume a regular diet, and two patients could eat a soft diet. All patients regained normal or near-normal speech and had an acceptable appearance. The described refinement of the composite radial palmaris longus free flap technique allows the reconstruction of the lower lip with a functioning oral sphincter; the technique can be recommended for patients who need large lower lip resection. It provides functional recovery of the reconstructed lower lip synchronizing with the remaining upper lip.
The combined loss of the Achilles tendon with overlying soft tissue is a reconstructive challenge. To achieve acceptable rehabilitation, such patients need skin coverage including functional repair of the Achilles tendon. This article presents four such patients who were treated successfully by means of an anterolateral thigh (ALT) composite flap with vascularized fascia lata. The size of the ALT flaps ranged from 10 to 16 cm in length and 6 to 9 cm in width. All flaps included vascularized fascia lata, which was rolled to serve as vascularized tendon graft (range 8 x 6 cm to 10 x 8 cm) for reconstruction of the Achilles tendon defect. Flap success rate was 100%. All patients could walk and climb stairs without support; however, mild difficulty when running was reported. Functional outcome of the recipient ankle and donor thigh morbidity were investigated by using a kinetic dynamometer comparing reconstructed sides with the healthy contralateral limbs. This assessment was performed in two patients at 2 years postoperatively. In the reconstructed ankles, isokinetic concentric measurements of dorsiflexion and plantar flexion showed a deficit of 30% and 40%, respectively. Functional evaluation of quadriceps femoris muscle contraction forces after free ALT composite flap harvest showed a 10% to 25% deficit. However, there were no difficulties in daily ambulating. In summary, the free composite ALT flap with vascularized fascia lata provides an alternative option for Achilles tendon reconstruction in complex defects.
The purpose of this study was to examine the feasibility of teleconsultation using a mobile camera-phone to evaluate the severity of digital soft-tissue injury and to triage the injury with regard to management recommendations. With a built-in 110,000-pixel digital camera, pictures of the injured digit(s) or radiograph were taken by surgical residents in the emergency room and transmitted to another camera-phone to be viewed by the remote consultant surgeon. A brief medical and trauma history of each patient was relayed also by mobile phone. The consultant surgeon then reviewed all of these patients in the emergency room shortly after the initial telemedicine referral. Separate triaging for each digital injury into three groups was recorded during remote teleconsultation and according to actual treatment by the attending surgeon as follows: group I, the injury could be managed with conservative treatment, such as secondary intention wound healing, or primary closure with or without bone shortening; group II, skin grafting or local flap coverage was required for management of the injury; and group III, microsurgery such as replantation or free flap coverage was necessary to deal with the injury. Later, triaging was also performed individually by three junior plastic residents according to image review and patient referral information. Teleconsultation through a mobile camera-phone was performed for 45 patients with injuries of 81 digits from January to May of 2003. Of these 81 digital injuries, there were 12 cases (15 percent) where disagreement of triaging occurred between the teleconsultation and the actual treatment by the attending surgeon. In image reviewing, there was 79 percent sensitivity and 71 percent specificity in remote diagnosis of the skin defect and 76 percent sensitivity and 75 percent specificity in remote identification of the bone exposure regarding the concordance of opinions of all three surgeons; there was significant discordance in triaging in 20 cases (25 percent), and the difference in triaging was partly attributed to the inability to show instances of tiny exposed digital bone or tendon in some cases under the low-resolution digital image and the situation of a bloody oozing wound. In some cases, the difficulty in evaluating the probability of primary closure of severely avulsed skin edges or the probability of executing replantation for finger amputation also contributed to different triaging outcomes. Two neglected diagnoses of transected digital nerves were found and influenced triaging, highlighting the importance of on-site physical examination during teleconsultation. The telemedicine system using a mobile camera-phone based on the global system for mobile communication is feasible and valuable for early diagnosis and triaging of digital soft-tissue injury in emergency cases, with on-line verbal communication and review of the transmitted captured image. This system has the advantages of ease of use, low cost, high portability, and mobility. With advances in hardware for digital i...
