Reconstruction of a full-thickness alar defect requires independent blood supplies to the inner and outer surfaces. Because of this, secondary operations are commonly needed for the division of skin flap from its origin. Here, we report a single-stage reconstruction of full-thickness alar defect, which was made possible by the use of a nasolabial island flap and septal mucosal hinge flap. A 49-year-old female had presented with a squamous cell carcinoma of the right ala which was invading through the mucosa. The lesion was excised with a 5-mm free margin through the full-thickness of ala. The lining and cartilage was restored using a septal mucosa hinge flap and a conchal cartilage from the ipsilateral ear. The superficial surface was covered with a nasolabial island flap based on a perforator from the angular artery. The three separate tissue layers were reconstructed as a single subunit, and no secondary operations were necessary. Single-stage reconstruction of the alar subunit was made possible by the use of a nasolabial island flap and septal mucosal hinge flap. Further studies are needed to compare long-term outcomes following single-stage and multi-stage reconstructions.

A large lateral facial defects especially a through and through defect of the cheek remains as challenging field of reconstruction for the head and neck surgeons. Closure of these wounds is technically troublesome due to the magnitude and location of the soft tissue and skin defect, functional and aesthetic consideration. optimal cancer surveillance, and desire for good nourishment. Most traditional methods dealing with these defects, including split-thickness skin graft, local and regional flaps as well as musculocutaneous flaps have their limitations. We applied four different methods for these reconstruction in four cases. We utilized temporal muscle flap, forearm free flap and secondary healing for repair of mucosal defects, and medial base cervicopectoral flap, pectoralis major myocutaneous flap and cervicofacial flap for the reconstruction of external skin defects. In one case, both sides were reconstructed with single forearm free flap. In our experiences, secondary healing could be one of the useful method for mucosal repair in the defect between upper and lower gingivobuccal sulcus. However, forearm free flap was thought to be more ideal for the cases with mandibulectomy. For the external repair, the regional skin flap was considered to be superior to pectoralis major myocutaneous flap or forearm free flap especially on color matching.

Various local flaps and distant flaps including tongue flap, palatal island flap, and buccal flap as well as skin grafts have been used for the reconstruction of oral mucosal defect. In the posterior region of oral cavity and the buccal cheek area, buccal fat pad can be used as a pedicled graft. The buccal fat pad is different from other subcutaneous fat tissue and it is easily accessible. There are many advantages in pedicled buccal fat pad graft for the closure of oral mucosal defect. The procedure is easy, there is no visible scar in the donor site, it is capable of reconstruction of various contour, and it has good viability. We had used buccal fat pad as a pedicled graft for the closure of oral mucosal defect after the excision of tumor and the oroantral fistula. From the results of these cases, we concluded that the use of the buccal fat pad flaps was worth of the consideration for the reconstruction of oral mucosal defect in the regions of the buccal cheek, and posterior oral cavity.

Background In contrast to defects of the mandible and mouth floor region, in the defect of maxilla, the availability of firmly attached oral and nasal mucosal linings is needed. In addition to it, in consider of operation field, operating convenience, and esthetics, reconstruction using prelaminated flap is strongly recommended. Therefore we consider the prelaminated flap through the cases that is reconstructed using prelaminated forearm flap and prelaminated scapular flap. Patients and Methods From 2001 to 2008, in OMFS SNUDH, there were 6 cases that had reconstruction using prelaminated forearm free flap and other 3 cases that had reconstruction using prelaminated scapular flap of maxilla. The average age of patients that were reconstructed using prelaminated forearm free flap was 47.5 years, the average prelaminated period (after $1^{st}$ operation ${\sim}$ until $2^{nd}$ operation) was 51.8 days and the average follow-up period after $2^{nd}$ operation was 35.3 months. As well, the average age of patients that were reconstructed using prelaminated scapular free flap was 37 years, the average prelaminated period (after $1^{st}$ operation ${\sim}$ until $2^{nd}$ operation) was 57 days and the average follow-up period after $2^{nd}$ operation was 42.3 months. Results Except 1 case that were reconstructed using prelaminated scapular flap, we could get firmly attached oral and nasal stable skin(mucosal like) lining, more adequate thickness flap than any other flap and improved esthetic and functional results in the other 8 cases that were reconstructed using prelaminated flap. The complications of the prelaminated forearm flap cases were inconvenient swallowing, sputum, limitation of mouth opening and difficult mastication. It came from flap shrinkage of the flap in some aspect, as well as other combined operations such as mass resection or RND. The difficult point of the reconstruction of prelaminated scapular flap was the possibility of vascular damage at preparation of flap in $2^{nd}$ surgery. The damage could cause the failure of the prelaminated scapular flap. And the skin-lining of the prelaminated flap had limitations, so it is needed to study about the cultured oral epithelium-lining flap instead of the skin-lining flap. Conclusion We considered about advantages, complications and notable things of prelaminated flap through maxillary reconstruction cases using prelaminated forearm flap and prelaminated scapular flap so far. Furthermore, we should go on studying for functional reconstruction of prelaminated fasciomucosal flap using cultured oral epithelium.

Background and Objectives: Oro-and pharyngocutaneous fistula after irradiation can lead to extensive wound necrosis and fetal complication such as carotid rutpure. So, there is a need to clean and cover the wound rapidly in these compromised patients. Pectoralis major myocutaneous (PMMC) flap has been presented for reconstruction of complex defects in these irradiated patients. We applied the double paddle PMMC flap for the simultaneous reconstruction of above complex defects and evaluated the it's clinical efficacy. Material and Methods: Retrospective chart review of three cases of simultaneous head and neck reconstruction after irradiation with double paddle PMMC. All patients received prior radiotherpy before development of complications. The double paddle PMMC flap was used for mucosal lining of the oral cavity and epithelial lining of external skin in 2 cases, for mucosal lining of the pharynx and epithelial lining of external skin in 1 case. Results: Considerable complications such as major flap necrosis or fistula did not occur in any of the cases, and simultaneous reconstruction was achieved in all cases without reoperations. Conclusion: Many extended defects such as oro-and pharyngocutaneous fistula involving cover and lining about the head and neck after irradiation can be rehabilitated by the double paddle pectoralis major myocutaneous flap.

Purpose: The radial forearm fasciocutaneous free flap is currently considered as the ideal free flap for reconstruction of mucosal and soft tissue defects of the palate. But the availability of stably attached oral and nasal mucosal lining is needed. In addition to this, for better operation field, operating convenience and esthetics, we planned a prelaminated radial forearm free flap. Methods: A 64-year-old male patient was admitted due to a $4{\times}4.5cm$ full through defect in the middle of the hard palate caused by peripheral T cell lymphoma with actinomycosis. In the first stage, the radial forearm flap was elevated, tailored to fit the hard palate defect, and then it positioned up-side down with split thickness skin graft. Two weeks later, the prelaminated radial forearm free flap was re-elevated and transferred to the palatal defect. One side covered with grafted skin was used to line the nasal cavity, and the other side (the cutaneous portion of the radial forearm flap) was used to line the oral cavity. Results: The prelamination procedure was relatively easy and useful. The skin graft was well taken to the flap. After 2nd stage operation, the flap survived uneventfully. There was no prolapse of the inset flap into the oral cavity and the cutaneous portion of the flap was mucosalized. The procedure was very successful and the patient can enjoy normal rigid diet and speech. Conclusion: The use of prelaminated radial forearm free flap for hard palate reconstruction is an excellent method to restore oral function. Based upon the result of this case, microvascular free flap transfer with prelaminated procedure is a valid alternative to the prosthetic obturator for palatal defect that provides an improved quality of life. It should be considered as an integral component of head and neck cancer therapy and rehabilitation.

The buccal mucosa is an effevtive and versatile intraoral grafting material. For adequate reconst ruction of avulsed lip, restoration of natural appearance and adequate lip function should be done. We treated avulsed upper lip defect which had been affected underlying orbicularis oris muscle as well as vermilion border. We chose cheek mucosa for upper lip reconstruction and performed surgical correction of avulsed upper lip with pedicled buccal mucosal flap. The result was very good because of its superior color and texture matching to remaining yermilion tissue.

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.

Background and Objectives : The radial forearm free flap is a useful reconstructive method of surgical defects after oral and oropharyngeal tumor resection. We evaluated the swallowing and speech outcomes of radial forearm free flap reconstruction for oral and oropharyngeal cancers. Materials and Methods : We retrospectively reviewed clinical data of 84 patients who underwent reconstructive surgery for oral or oropharyngeal cancer using radial forearm free flap from August 1994 to January 2007. Modified barium swallowing (MBS) was done in 100 patients and speech-language assessment was done in 23 patients by a speech-language pathologist. Results were analyzed according to the swallowing functions and the speech-language assessments. Results : According to the results of MBS which was done postoperatively, aspiration occurred in three patients and velopharyngeal insufficiency occurred in four patients who had been reconstructed with multilobed free flap due to large mucosal defects. There was one patient who exhibited severe articulation impairment out of 23 patients. However, 19 patients out of 23 patients showed excellent intelligibility in speech. Conclusion : We concluded that the radial forearm free flap technique is an excellent reconstructive method for the restoration of palatal and pharyngeal function in oral and oropharyngeal cancer patients.
