The nasolabial flap has been used for reconstruction of moderate size intraoral defects. The nasolabial fold area provides an ample supply of tissue with a good color and texture match. The nasolabial flap classified advancement flap, inferiorly-based flap, superiorly-based flap. The flap is based inferiorly, so that it can easily be rotated to the intraoral defects. The nasolabial flap is chosen for the repair of various intraoral defects because of its simple elevation, proximity to the defect and its rich subcutaneous blood supply of a island flap. The subjects were 6 patients with nasolabial flap, who had reconstruction of moderate size intraoral defects. We have found the inferiorly-based nasolabial flap with a subcutaneous pedicle useful in the primary repair of surgical defects of the buccal mucosa, edentulous mandibular ridge, maxillary alveolus area and soft palate in these patients. There was no complication except one case. Intraoral hair growth was a minor problem of this patient. We thought that the inferiorly-based nasolabial flap is a useful technique for reconstruction of various intraoral defects.

The loss of mandibular continuity due to trauma, neoplasm, or infection results in major esthetic and biologic compromise. The reconstruction of the mandibular bone defect still poses a challenge to oral and maxillofacial surgeons. There have been a number of variety graft materials. Among them, free block bone graft with rigid fixation has been widely used. However, cases using free block bone grafts may lead to a marked invasion of the donor site, mal-union, and absorption of the block bone. In this respect, particulate cortical bone using a titanium mesh tray can be an effective alternative option in order to achieve a proper bone contour and good oral rehabilitation. We have developed an intraoral approach for the mandibular reconstruction method using a titanium mesh tray with autogenous particulate cortical bone graft.

Head and neck reconstruction poses unique challenges in rehabilitating surgical defects in terms of integrity, function, and form. The radial forearm free flap (RFFF) has been widely used for defect coverage, especially in the head and neck area, but its versatility allows it to be used for soft-tissue reconstruction in various parts of the body. The vascular features of the flap are quite constant and reliable. Nevertheless, abnormalities of the forearm vascular tree have been described over the decades. We report a case of intraoral reconstruction after verrucous carcinoma recurrence in a 74-year-old woman with an unusual forearm flap, which we called the median forearm free flap, based on a median branch of the radial artery that was preoperatively detected using handheld Doppler ultrasonography. The distally located skin paddle was predominantly supplied by the aberrant median vessel with its perforators. The flap was thus safely harvested with this atypical pedicle. Successful reconstruction of the intraoral defect was achieved, with an uneventful postoperative course.

Many congenital and acquired defects occur in the maxillofacial area. The buccal fat pad flap (BFP) is a simple and reliable flap for the treatment of many of these defects because of its rich blood supply and location, which is close to the location of various intraoral defects. In this article, we have reviewed BFP and the associated anatomical background, surgical techniques, and clinical applications. The surgical procedure is simple and has shown a high success rate in various clinical applications (approximately 90%), including the closure of oroantral fistula, correction of congenital defect, treatment of jaw bone necrosis, and reconstruction of tumor defects. The control of etiologic factors, size of defect, anatomical location of defect, and general condition of patient could influence the prognosis after grafting. In conclusion, BFP is a reliable flap that can be applied to various clinical situations.

Purpose: The purpose of this clinical retrospective study was to evaluate our experience of radial forearm free flap for reconstruction of the oral cavity. Material and methods: From 1997 to 2006, 50 radial forearm free flaps were employed for head and neck reconstruction in 50 patients at department of oral and maxillofacial surgery, Yonsei University, Korea. Data were obtained from chart review, and clinical follow-up. Results: Patients' age ranged from 26 to 82 years (mean 53.2). There were 39 men and 11 women. 43 of the 50(86%) patients had squamous cell carcinoma. The total flap survival were 47(94%), complication rate were revealed for 15(30%). Conclusion: In the reconstruction of soft tissue within the oral cavity, several free flaps have been used. Because of its constant anatomy, long pedicle allows a hypothetic vascular anastomosis in the contralateral neck, contourability for various type of oral defects, pliability and can be used simultaneous reconstruction in intraoral and extra oral defects, the radial forearm free flap constitutes one of the best choice of intraoral soft tissue reconstruction.

Vascularized iliac crest flap include bone tissue of good quality and quantity for mandible segmental defect. Even if fibular flap can contain longer bone tissue, iliac crest has esthetic shape for mandible body reconstruction and large height for implant. Conventional vascularized iliac crest osteomyocutaneous flap is too bulky for reconstruction of intraoral soft tissue defect. But modified flap can reduce soft tissue volume, so is good for functional reconstruction of oral mucosa. It takes only one month for completely replace oral mucosa. The final mucosal texture is much better than other skin paddle flap, especially for implant prosthesis. Donor site morbidity of this method looks same level or less with other modalities functionally and socially. In case of oral mucosa-mandible combined defect, vascularized iliac crest with internal oblique muscle flap shows good outcomes for hard and soft tissue.

Purpose: The objective of this study was to evaluate the outcomes of using the free flap in the reconstruction of maxillary defects. Methods: 27 consecutive cases of maxillary reconstruction with free flap were reviewed. All clinical data were analyzed, including ideal selection of flap, time of reconstruction, recurrence of cancer, postoperative complications, flap design, and follow-up results. The main operative functional items, including speech, oral diet, mastication, eye globe position and function, respiration, and aesthetic results were evaluated. Results: Among the 24 patients who underwent maxillary reconstruction with the free flap, 14 patients underwent immediate reconstruction after maxillary cancer ablation, and 10 patients underwent delayed reconstruction. There occurred 1 flap loss. Recurrences of the cancer after the reconstruction happened in 2 cases. Postoperative complications were 3 cases of gravitational ptosis of the flap, 2 cases of the nasal obstruction, and 1 case of fistula formation. Out of 27 free flaps, there were 15 latissimus dorsi myocutaneous flaps, 5 radial forearm, 4 rectus abdominis myocutaneous flaps, 1 scapular flap, 2 fibula osteocutaneous flap, respectively. Flaps were designed such as 1 lobe in 9 cases, 2 lobes in 9 cases, and 3 lobes in 5 cases. Among the 14 patients who had intraoral defect or who had palatal resection surgery, 2 patients complained the inaccuracy of the pronunciation due to the ptosis of the flap. It was corrected by the reconstruction of the maxillary buttress and hung the sling to the upper direction. All of the 14 patients were able to take unrestricted diets. In 6 patients who had reconstruction of inferior orbital wall with rib bone graft, they preserved normal vision. Aesthetically, most of the patients were satisfied with the result. Conclusion: LD free flap is suggested in uni-maxilla defect as the 1st choice, and fibular osteocutaneous flap and calvarial bone graft to cover the larger defect in bi-maxilla defect.

In the maxillary anterior region, reconstruction of the localized alveolar ridge defect is very important in enhancing the esthetics of fixed partial denture. A 40-year-old female patient presented with a chief complaint of the inconvenience and unesthetic problem of 3-unit maxillary anterior prosthesis due to alveolar ridge resorption. After removal of old prosthesis, intraoral examination revealed moderate (buccolingually 4 mm) ridge deficiency in missing tooth region, leading to the diagnosis of Class I alveolar ridge defect. One of the reconstruction techniques to overcome this problem might be a technique that combines two types of soft tissue augmentation techniques. The purpose of this paper was to demonstrate the new combined technique of roll flap and combination onlay-interpositional graft utilized to acquire sufficient dimension of recipient area by one time of operation and to present the esthetic improvement of fixed partial denture by using this procedure in case of maxillary anterior localized ridge defect.

Free grafting of oral mucosa for minor oral reconstruction was first described by Propper in ridge extension surgery. Situation calling for mucosal grafting procedures may relate to periodontal surgery, minor and major preprosthetic surgery, implant surgery, reconstruction in deformity cases after trauma, congenital cleft, gross atrophy and ablative tumor surgery. In the cases of 9 patients with mucosal defect of intraoral or orbital cavity after wide excision of tumor, preprosthetic surgery, and orbitoplasty, full-thickness mucosal graft were used to close a large defect. Four patients received buccal mucosal graft for preprosthetic surgery or orbitoplasty, one patient had benign tumor and the others had malignant tumors located on the palate or upper alveolus. Buccal mucosal graft donor site morbidity and trismus were minimal and healing of surgical defect was satisfactory. So we present the case with review of literatures.
