OBJECTIVETo introduce the applied anatomy of pedicled buccal fat pad (BFP) graft and a series of histological changes in the healing process of BFP as an uncovered pedicled graft.

METHODSThe healing processes of BFP are demonstrated via uncovered pedicled grafts on rabbits in histological examination. Uncovered buccal fat pads were used to repair soft tissue defects in rabbit oral cavities.

RESULTSThe uncovered buccal fat pads showed complete epithelialization of their oral surfaces at 6 to 8 weeks after surgery and were slowly replaced by fibrous tissue.

CONCLUSIONSAdvantages of the pedicled buccal fat pad graft include an anatomic region that is consistent and easy to excise. The operation can be performed in one incision, affecting neither appearance nor function of the area. Use of the buccal fat pad provides a good reconstruction of soft tissue defects in the mouth.

A new method using the ideal mid-facial line as the navigating reference was introduced to improve the outcome of cleft lip repair. Using the verticle coordinate crossing the middle point of the intercanthus line, surgeons could observe and correct the distortion of the fine structures in labial-nasal area. This laser projecting mid-facial-line navigation was repeatable, while not interfere the operating. In conclusion, generalizing laser navigation is a valuable supplementary for cleft lip repair.

OBJECTIVETo discuss the value of endoscopic technique in maxillofacial and neck regions.

METHODSThis retrospective review included 102 clinical patients with superficial masses in maxillofacial and neck regions. The indications, incisions, endoscopic space preparation and the key points of operative process were analysed.

RESULTAll of the results were satisfying.

CONCLUSIONThe endoscopic technique in treating superficial masses in maxillofacial and neck regions had the advantage of wide indications, multiple incision choices, easy control of operative layers and less complications. And the recent and remote effects were excellent.

BACKGROUNDFunctional reconstruction of the jaw defect due to tumor resection poses a challenging problem in maxillofacial surgery. The osteocutaneous fibula free flap in combination with simultaneous or second stage insertion of dental implants has exhibited growing popularity for such reconstructions. This study was aimed at evaluating the clinical status and the success rates of dental implants inserted in fibula-free flaps for orofacial reconstruction following ablation of tumors.

METHODSWe conducted a clinical follow-up study based on 29 patients after oral tumor surgery, who received vascularized fibula bone grafts and endosseous implants for functional jaw reconstruction during a 5-year period. The follow-up protocol included clinical examination and radiological evaluation. The clinical records of the patients were reviewed retrospectively. Information on treatment modalities, dentition, implant parameters, and prostheses was collected and analyzed.

RESULTSIn general, a high primary stability for implants placed into the free fibula grafts was achieved. The 1-year and 5-year cumulative survival rates of the implants were 96% and 91%, respectively, using the Kaplan-Meier method. The 1-year and 5-year cumulative success rates of implants placed into the fibula bone grafts were 95% and 87%, respectively. The main reasons for failure of the dental implants were infection, tumor recurrence and soft tissue proliferation. The fibula flap presents many advantages for implant placement, but its limited height sometimes makes implant-supported prosthetic rehabilitation difficult.

CONCLUSIONSVascularized fibula bone grafts provide a firm basis for the placement of dental implants in jaw reconstruction. Implants placed in fibula bone grafts were shown to integrate normally. The double-barrel technique, or increasing the height of the fibula flap by vertical distraction osteogenesis before implant placement in the mandible, is desirable from a functional and esthetic point of view.

OBJECTIVETo investigate an safe and effective new technology (treatment) to repair maxillofacial region penetrating defect.

METHODSThe lower trapezius musculocutaneous flap is parallel just like as two leaves which is connected to each other, and was folded to provide the liner of oral cavity and external cover.

RESULTSTotally twelve folding lower trapezius musculocutaneous pedicle flap survived. Postoperative follow-up for 1 approximately 3 years, the patients restored the function as well as the shape of maxillofacial region.

CONCLUSIONSThe lower trapezius musculocutaneous pedicle flap is a suitable material for maxillofacial region reconstruction, further more, the successful rate is perfect.
