Tongue reconstruction with anterolateral thigh flap for middle-late stage tongue cancer patients / 中华显微外科杂志

Objeetive To investigate the outcome of microvascular reconstruction of the tongue with anterolateral thigh flaps in the treatment of middle-late stage tongue cancer patients. Methods From December 2003 to March 2007,nine patients underwent simultaneous reconstruction of the tongue and oral floor defects with anterolateral thigh flaps after resection of squamous cell carcinoma of tongue.The flaps ranged from 7 cm×10 cm to 10 cm×12 cm in size,and were adjusted to the defect of the tongue and oral floor.The vascular pedicle included descending branch of the lateral femoral circumflex artery and the accompanying veins.The outcome of reconstruction was evaluated by follow-up examinations,considering the contour and mobility of the reconstructed tongues,the swallowing function and the speech function.Results All of the donor sites were closed directly,with minimal donor-site morbidity. All patients recovered unevenffully from surgery,with no immediate postoperative complications:no flap necrosis,no wound infection or wound dehiscence.The transplanted flaps survived well.The average follow-up period was 18 months.During the follow-up period there was no tumor recurrence and the contour of the reconstructed tongues showed sufficient bulk.The patients demonstrated good mobility of the reconstructed tongue.The swallowing and speech function recovered satisfactory.Two months postoperatively the patients were able to ingest a solid or semisolid diet,and six months postoperatively the patients developed intelligibe language.Conclusion The anterolateral thigh flaps are suitable and reliable for the microsurgical reconstruction of the large defects caused by middle-late stage tongue cancer.

Clinical significance of monitoring-flap in massive compound bone grafts for repairing massive bone defects in extremities / 中华显微外科杂志

Objective To explore the significance of designing with monitoring-flap in massive com- pound bone grafts for repairing massive bone defects in extremities.Methods From January 2001 to De- cember 2004,large bone defects in 19 patients(11 men and 8 women,age:6 to 35 years,mean age:18.6 years)were repaired by vascularized free fibular transplant with a monitoring-flap combining with massive deep frozen bone allografts.Average length of the bone defects was 16.6 cm(range,12 to 25 cm).A 7 days' con- tinuously clinical examination including observing the color,turgor,temperature,capillary refill,and bleeding after a needle sticking of the monitoring-falps were used postoperatively,if any one of these were abnormal,the circulation of the compound bone grafts must be in danger and some measures such as re-operation should be taken immediately.Dynamic image analysis was used for evaluating the bone union.Results One monito- ring-flap was vascular artieulo,and the articulo was relieved after exploration and resection of vein thrombus; another one was marginal part necrosis;the remains were normal.All of monitoring-flaps healed normally after 23.2 months(range,6 to 54 months)follow-up.15 patients had the radiographic evidence of bone unions 3 months after surgery.11 patients had been removed intermal fixation,complete bone unios were found one year postoperatively.Conclusion Designing with monitoring-flap in massive compound bone grafts for repairing massive bone defects,and can clearly understand the circulatory statue of compound bone grafts and early pre- dict the final results of massive bone allografts.
