Objective To analyze our clinical results of head and neck reconstruction using microsur- gical free flap transfer techniques.Methods The free flap donor sites with long vascular pedicle and large diameter of vessel were routinely chosed,and chose receipt vessels with large diameter and proper position, and perform vessel ananstomosis under surgical loups instead of microscope.The un-buried free flap with a mo- nitoring window were harvest,and do double venous anastomoses in some flaps to ensure adequate venous out- flow.Results From May 1999 to March 2005,1066 consecutive free flap transfers were used to reconstruct head and neck defects.The overall success rate of free flap was 98.3%.The vessel thrombosis rate was 3.1%,and the flap salvage rate was 45.5%.Conclusion Head and neck reconstruetion using microsurgi- cal free flap transfer technique is safe and reliable,and good clinical results can be obtained.

OBJECTIVETo compare the impact of various types of neck dissection on postoperative shoulder function.

METHODSThe shoulder functions of 66 patients with oral squamous cell carcinoma (OSCC) and cN0 necks who underwent various types of neck dissection were evaluated by Constant's shoulder function test and neck dissection impairment index at least 12 months after surgery.

RESULTSThe patients with accessory spinal nerve reserved had better shoulder function than those with accessory spinal nerve resected. In the group with accessory spinal nerve reserved, the patients receiving selective neck dissection (SND) showed better shoulder function than those with modified radical neck dissection (MRND). The shoulder dysfunction and pain arising from SND were minor in patients with selective neck dissection.

CONCLUSIONSThe shoulder function after SND was superior to those after RND and MRND.

OBJECTIVETo evaluate the temporomandibular joint (TMJ) function after mandible reconstruction with free fibula flap and with different condyle treatment.

METHODSForty-one cases of mandible and condyle defects following benign tumor resection were reconstructed with fibula free flap, with the condyle being reconstructed by three methods: placement of the distal end of the fibula flap into the glenoid fossa, the fibula serving as the condyle (24 cases); attachment of the resected condyle as a nonvascularized transplant to the end of the fibula flap (5 cases); condyle preservation plus vascularized fibular reconstruction (12 cases). The postoperative TMJ function was evaluated by Fricton function index.

RESULTSNo TMJ ankylosis occurred in all patients. There were no significant differences in aesthetics, deglutition and speech function among the three groups; but there were significant differences in TMJ function index (DI, CMI) among different condyle treatments. Condylar preservation showed better TMJ function than fibula used as a substitute for condyle.

CONCLUSIONSPreservation of condyle during free fibula mandibular reconstruction can improve patients' TMJ function. The location and shape of fibular condyle were important factors that could influence the outcome the condyle reconstruction.

OBJECTIVETo evaluate the reliability and effectiveness of free flap transfer with double vein anastomosis for reconstruction of head and neck defects.

METHODSOne hundred and sixty-eight cases of free flap transfers with double vein anastomosis for head and neck reconstruction from September 1999 to April 2003 were reviewed. There were 92 males and 76 females. The age range was 11 to 79 years old, with the average of 44.6 years old. Data concerning the operation included site, stage and histology of tumor, defect description, design of free flap, recipient vessel free flap survival and complications.

RESULTSAmong 168 free flaps, there were 126 free fibula flaps, 32 radial forearm flaps, 7 rectus abdominis flaps, one scapular flap, one jejunal flap, and one anterolateral thigh flap. The overall success rate of free flap was 99.4%. One fibula flap was lost because of arterial thrombosis. No venous thrombosis occurred in this group.

CONCLUSIONFree flap transfer with double vein anantomosis for head and neck reconstruction improves the outflow of free flap, reduces the venous thrombosis rate, and ensures a high success rate of free flaps.

OBJECTIVETo evaluate speech outcomes in patients of maxillary reconstruction with free fibula composite flap.

METHODSSpeech measurements of 20 patients of maxillary reconstruction with free fibula composite flap were collected. Palatopharyngeal valve, the symmetry and movement of soft palate, hypernasality and nasal emission were examined by nasoendoscopy. At the same time the speech intelligibility was measured.

RESULTSNo palatopharyngeal valve insufficiency was found and all the soft palates had good symmetry and movement. The average speech intelligibility was 98.4%.

CONCLUSIONSFree fibula composite flap can reconstruct the phonatory structure and support the function of soft palate, which can restorate speech function well. It is a good choice for maxillary reconstruction.

OBJECTIVETo analyze the rationale and feasibility of maxillary reconstruction using free fibula-flexor hallucis longus myofascial flap.

METHODSNine consecutive cases of maxillary reconstruction using free fibula-flexor hallucis longus myofascial flaps from August of 2002 to August of 2003 were reviewed. Data concerning the operation included description of maxillary defect, design of the fibula flaps, recipient vessel and complications.

RESULTSOne flap experienced venous thrombosis after operation, and the flap was salvaged after exploration. All the flaps survived completely with the overall success rate of 100%, as well as the 100% survival of all fibula-flexor hallucis longus myofascial flaps.

CONCLUSIONSMaxillary reconstruction using free fibula-flexor hallucis longus myofascial flap without skin paddle is feasible and reliable.

OBJECTIVESThe value of supraomohyoid neck dissection used in treating oral squamous cell carcinoma was discussed.

METHODSTwenty-seven cN0 patients with oral squamous cell carcinoma were entered into the study. Supraomohyoid neck dissection was performed to remove the lymphatic tissue of level I, II, and III. The operation duration and shoulder function were recorded.

RESULTSThe average operation duration was (1.6 +/- 0.2) h. Nineteen percent (5/27) of the cN0 neck were proved positive pathologically which included two cases in level I and four in level II (one case had both level I and II metastases). Shoulder function recovered in three months after operation. All patients were followed up from two years to four years and none of them had local or neck recurrence.

CONCLUSIONSSupraomohyoid neck dissection is a right choice for cN0 patients with oral squamous cell carcinoma with its advantages in both curing neck lymphatic metastases and preserving neck and shoulder contours and functions.

OBJECTIVETo describe a new method of accessory nerve defect reconstruction with sternocleidomastoid muscle-great auricular flap.

METHODSThirty-four cases receiving traditional radical neck dissection were divided into two groups: single neck dissection group (n = 19) and accessory nerve reconstruction group (n = 15). Surgical procedure of the reconstruction was described in detail. Postoperative shoulder functions were compared between the two groups.

RESULTSAccessory nerve reconstruction group experienced much better shoulder function recovery than that in single neck dissection group.

CONCLUSIONSReconstruction of accessory nerve defects with sternocleidomastoid muscle-great auricular nerve flap is simple, effective and complication-free.
