Objective To reconstruct the maxillary defect by usingfree vascularized iliac osteomusculocutaneous flap combined with immediate zygomatic implantation for early rehabilitation of maxillary contour and masticatory function. Methods In August 2003, the patient presented with deformity ofleft middle face(Brown Ⅱ type defect) after subtotal maxillectomy. After hospitalization, a set of preoperative preparations were made, including spiral CT scanning, manufacture of nature size anatomical model and implantation protocol design. The maxillary defect was reconstructed with free vascularized iliac osteomusculocutaneous flap combined with simultaneous insertion of one Br¨nemark zygomatic implant and two general implants. Six months later the prosthesis were placed. Results The vascularized osteomusculocutaneous flap survived, the osseointegration was observed between bone and implant 6 months later. The contour of face and palate was satisfactory, the normal occluding relation was gained. The average masticatory force of operative side was 76.3% of the normal side. No tumor recurrence was noticed during the follow-up of 14 months. Conclusion It is a reliable method for functional reconstruction of maxillary defect via vascularized iliac osteomusculocutaneous flap combined with immediate zygomatic implantation.
Objective To investigate the clinical effect of free forearm flap and titanium mesh in repairing maxillary defects. Methods From January 2002 to November 2002,partial maxillectomy or maxillectomy wereperformed in 3 patients with maxillary gingival carcinoma, in 1 patient with palatine mucoepicermoid carcinoma and in 1 patient with maxillary sinus carcinoma. Maxillary defects were reconstructed withfree forearm flaps ranging from 4 cm×5 cm to 6 cm×7 cm and titanium mesh.The effect was estimated by clinical examination, CT and nasopharyngoscope. Results Five cases were followed up 515 months. All the flaps were alive. Facial, alveolar process and palatal contours were restored well. Epithelium was found on the nostril surface of the titanium mesh. The functions of speech and chew were restored well. Conclusion A combination of the free forearm flap and titanium mesh is an ideal method in reconstruction of maxillary defects.
OBJECTIVE: To investigate the method and clinical effect of temporal fascia flap, free forearm flap, free iliac bone transfer and immediate implant on reconstruction of maxillary defect. METHODS: From February 1999 to July 2002, 8 cases of maxillary defects due to excision of cancer were repaired immediately with temporal fascia flap, free forearm flap, free iliac bone transfer and implant. Out of 8 patients, there were 6 males and 2 females, aged 32-49 years, with a disease course of 3 months to 2 years. RESULTS: Free iliac bone and forearm flap survived in all 8 cases. Osseo-integration could be seen and the implants could be used for denture repair and chew function. After 6-12 months, X-ray examination showed iliac bone healing; facial shape and functional restoration were satisfactory. CONCLUSION: Temporal fascia flap, free forearm flap, free iliac bone transfer and immediate implant is an ideal method to repair maxillary defect immediately and reconstruct its function.
