Abstract:
BACKGROUND: There are many advantages in treatment of deglovinginjury in hand with compatible grafting of temporoparietal fascial flaps(TFFs), while there are few relevant reports in China.OBJECTIVE: To evaluate function and appearance of hands after restora-tion of soft tissue defects with compatible grafting of TFFs.DESIGN: Case retrospective analysis.SETTING: Department of Maxillofacial Surgery, Plastic Surgery Hospital,Peking Union Medical College, Chinese Academy of Medical Sciences.PARTICIPANTS: Eleven patients with hand injuries received compatiblegrafting of TFFs in the Department of Maxillofacial Surgery of PlasticSurgery Hospital, Peking Union Medical College, Chinese Academy ofMedical Sciences from January 2001 to May 2005 were selected including8 males and 3 females with a mean age of 30 years. All subjects participat-ed in the observation and analysis voluntarily. All patients presented expo-sures of tendon, bone or joint.METHODS: Preoperative location was done with Doppler or palpation methods and the orientation of temporal vascular nerve tracts were labelled. Re-cutization of surface of fascial flap was achieved through fullthickness skin transplantation. Sizes of fascial flaps were limited between 10 cm×9 cm and 4 cm×6 cm. Follow-up was 8 months (6-11 months),the items of which included postoperative functional inspection and satisfactory degree of appearance. Ratio of total active range of motion (AROM) with joints injured and corresponding uninjured joints were used for functional evaluation, and the meso was zero. Functional rehabilitation was divided into 3 grades according to the ratio: Good as the ratio above 0.75, fair as the ratio between 0.5 and 0.75, poor as the ratio below 0.5. Evaluation on appearances of hands contained satifactions of both patients and doctor including whether there were fat and clumsy or visible scars.MAIN OUTCOME MEASURES: Postoperative functional recovery of hand after compatible grafting of TFFs.RESULTS: Eleven patients with hand injury were included and 4 patients withdrew from the study. ①Fascial flaps of 9 patients completely survived,one patient got partial necrosis due to venous injury during flap harvesting,and wounds spontaneously healed by exchanging dressing. Venous crisis was found in the 3rd day of postoperation in one patient during operation research (OR) and there were thromboses in anastomosed veins due to the folding of overlong vein, which was unobstructed after reanastomosis, while there were sporadical scars in the raw surfaces. ②Functional recovery of hands were good in 4 cases and better in 3 cases, 4 cases withdrew from the study. Both doctors and patients were satisfied with the recovery status of appearance of hands.CONCLUSION: It is better to simultaneously adapt compatible grafting of TFFs and re-cutization in restoration of tissue defects in hands such as exposures of bone and tendon. Better aesthetic results can be achieved with out second flap restoration. Most of all, the supple texture of fascial tissues provides a good gliding environment for functional recovery of tendon and joint, moreover, scars in donor sites are well camouflaged without functional lesions.
