ABSTRACT

Objective To investigate the free tissue flap in oral and maxillofacial surgery in head and neck cancer defects application value .Methods 154 cases of oral and maxillofacial tissue defects ,50 cases of tongue-mouth floor area defects ,13 cases of cheek palate defect ,35 cases of maxillary defect ,27 cases for the mandible , 28 cases of maxillary defects were selected .All patients underwent defect for free flap surgery oral and maxillofacial defects,of which 43 cases of forearm flap,fibula composite flap 15 cases,24 cases of diaphragmatic bone flap ,antero-lateral thigh flap flap 26 cases,free chest major muscle flap in 12 cases,15 cases of fibula flap,the other free flap, 34 patients were retrospectively analyzed the survival rate and postoperative complications .Results 154 cases of free flap,the survival rate was 96.75%.Which forearm flap survival rate was 97.67%;phrenic bone flap survival rate was 95.83%;anterolateral thigh flap survival rate was 96.15%;free pectoralis major flap survival rate was 91.67%;fibu-la flap survival was 93.33%;anterolateral thigh flap survival rate was 100.00%.Determination of the language defini-tion,154 patients,138 patients more than 90.00%clarity,while 16 patients more than 70.00%speech intelligibility. Conclusion Oral and maxillofacial traumatic tissue defects using free tissue flap reconstruction has certain safety and efficacy,the most common forearm free flap and fibula .Traumatic soft tissue defects in the early positive selection of free flap can effectively prevent tissue deformation and shift repair success rate ,postoperative language function recov-ery is good,it is worthy of clinical application .

ABSTRACT

Between May 2009 and February 2012,60 patients scheduled for laparoscopic appendectomy were randomly assigned to receive either transumbilical single-port laparoscopic appendectomy (TUSPLA) or three-port laparoscopic appendectomy (TPLA).The operative duration was significantly longer in TUSPLA than TPLA cases.No statistically significant differences existed in hospital stay,visual analog scale (VAS) score,analgesia requirement or complication rate.The abdominal scar was inconspicuous for TUSPLA.It suggested that TUSPLA with conventional instrumentation is technically feasible and safe with scarless healing.
