Purpose: Squamous cell carcinoma(SCC) of the lower lip is the most common malignant tumor comprising 90% of all lip SCC. The typical picture of SCC of the lower lip is of an ulcerated lesion with raised margins. Surgery is the treatment of choice for SCC of lower lip. Depending on the location and size of the tumor, different types of flaps are used. We used new method - 'both buccal mucosa transposition flap' for the reconstruction of the near total mucosal defect of the lower lip. Methods: This 67 - year - old men presented with the crusted $1cm{\times}1cm$ sized ulceration of the lower lip that was arised 30 years ago. There were no size and color change, except the bleeding and ulceration. At first, We diagnosed the SCC through the incisinal biopsy. Then We performed the wide excision of the tumor and reconstruction of the lower lip. After the excision of the whole tumor, the defect was measured at $8cm{\times}3.5cm$. We designed the buccal mucosa transposition flap taking care to avoid the parotid duct. The flap was made in a triangular shape for the reconstruction of defected lower lip. The donor site defect can be sutured primarily. Results: A patient in this study had no postoperative complications such as necrosis, dehiscence, infection of the flap or donor site. Reconstructed lower lip is relatively close to that of the natural lip; More satisfactory aesthetic and functional results can be obtained by using this technique rather than other techniques. Conclusion: 'Both buccal mucosa transposition flap' is reliable method for the reconstruction of the large lower lip mucosal defect. The operation is simple and performed in one stage, with no postoperative complications. This technique can offer consistently good functional and esthetic outcomes after reconstruction of lower lip mucosal defect.

Lip defects often occur following wide excision as a surgical treatment for squamous cell carcinoma of the oral cavity. Defects larger than one-half of the lip cannot be closed primarily and require flap surgery. Reconstruction of the oral sphincter function can be achieved by means of a local flap using the like tissue, rather than with a free flap utilizing different tissues. A defect of the lower lip requires reconstruction using different techniques, depending on its size and location. Herein, we present the case of a patient exhibiting a lip defect spanning more than two-thirds of the lower lip, after a wide resection due to squamous cell carcinoma. The defect was reconstructed using an Abbe flap and a staircase flap. Revision was performed after 16 days. The patient's oral competencies were fully restored 3 months postoperatively, and the esthetic results were ideal. Based on our experience, a combination of the Abbe and staircase flaps can produce excellent functional and esthetic outcomes in the reconstruction of a lower lip with a large defect. It can serve as a reliable reconstruction option for defects spanning more than two-thirds of the lower lip, not including the oral commissures.

Generally, if the size of a lip cancer defect exceeds 30% of the lower lip, a local flap or free flap is recommended. However, defects up to 50% of the lower lip in size have been reconstructed successfully by primary closure without a local flap or free flap. In one case, an 80-year-old male farmer who had smoked for more than 50 years presented with squamous cell carcinoma of the lower lip and underwent mass resection and supraomohyoid neck dissection. The defect accounted for almost 2/3 of the lower lip and was repaired by primary closure with V-shaped resection. Biopsy results confirmed pT2N0cM0 stage II disease with clear margins. In another case, a 68-year-old male also presented with squamous cell carcinoma of the lower lip and underwent mass resection. The defect accounted for about half the size of the lower lip but was repaired by primary closure with V-shaped resection. Both patients experienced no discomfort while eating or speaking and were satisfied with the cosmetic and functional outcomes with no evidence of recurrence. Thus, direct closure can be considered even in large lower lip cancers.

Background: The mental V-Y advancement flap method is useful for reconstruction of lower lip defect because of its many advantages. However, it is not easy to select the optimal reconstructive method for the vermilion defect that remains after application of the mental V-Y advancement flap. In choosing the representative surgical method for vermilion mucosal reconstruction including mucosal V-Y advancement flap, buccal mucosal flap, and buccal mucosal graft. We describe an efficient technique to large lower lip defects combining mental V-Y advancement flap and buccal mucosal graft Methods: This study included 16 patients who underwent reconstructive surgery for full-thickness and large defect (> half the entire width) of the lower lip from October 2006 to September 2017. The operation was conducted using mental V-Y advancement flap with various vermilion mucosal reconstruction methods considering the location of the defect and the amount of residual tissue of the lip coloboma after excision. Results: All patients underwent mental V-Y advancement flap. In vermilion mucosal reconstruction, five patients underwent mucosal V-Y advancement flap, three underwent buccal mucosal flap, and eight underwent buccal mucosal graft. There were good aesthetic and functional results in all patients who underwent buccal mucosal graft. However, two patients who underwent mucosal V-Y advancement flap complained of oral incompetence, and all patients who underwent buccal mucosal flap had oral commissure deformity. Conclusion: Buccal mucosal graft combined with mental V-Y advancement flap can produce suitable functional and aesthetic outcomes in near total lower lip reconstruction in patient with large mucosal defect including vermilion portion.

Squamous cell carcinoma is the most common cancer occurring in the oral cavity and oncologic wide cancer excision is a major cause of large lip defects. Large lower lip defect reconstruction with good functional and aesthetic results has always presented a challenge for plastic surgeons. There are various lower lip reconstruction methods depending on its size, location, and surgeon's expertise. This is a case of a large defect spanning more than two-thirds of the lower lip after wide excision due to squamous cell carcinoma. The Karapandzic flap was used to reconstruct the defect with a commissuroplasty carried out in a second operation, which yielded a relatively good functional and aesthetic result. No recurrences or metastases were observed within a one year follow-up period.

Many types of upper lip reconstruction have been introduced to treat defects after a tumor excision or trauma. The authors treated two cases of upper lip defects. A 35-year-old woman presented with a squamous cell carcinoma of the left upper lip that had invaded the corner of the mouth. After resecting the tumor, the defect was $3.7{\times}3.5cm$ in size. A 52-year-old woman presented with a dog bite of the right upper lip. The defect measured $4.0{\times}2.2cm$ in size. The two cases were reconstructed by combined rotation and advancement of a cheek flap. This technique produced a good functional outcome that allowed for oral competence and created an opening of adequate size. A combination of rotation and an advancement flap can be used to treat upper lip defects in a single-stage procedure. This approach produces a good functional and cosmetic outcome.

Lower lip reconstruction in cases with a full-thickness defect over one-third of the vermilion is challenging. Numerous conventional techniques have been applied with unsatisfactory surgical outcomes because of microstomia and oral commissure blunting due to shortened horizontal lip length. Herein, we present a case in which a full-thickness lower lip defect of more than one-third of the horizontal lip length was covered with a novel mucosal roofing flap reconstruction to minimize the loss of horizontal lip length and to preserve mouth opening. No recurrences or metastases were observed during 3 years and 6 months of follow-up, with horizontal lower lip length maintained and mouth opening of 2.5 finger breadths.

The closure of a wide alveolar cleft and fistula in cleft patients and the reconstruction of a maxillary dentoalveolar defect in bilateral cleft lip and palate (BCLP) patients are challenging for both orthodontists and oromaxillofacial surgeons. It is due to the difficulty in achieving complete closure by using local attached gingiva (palatal flap) and the great volume of bone required for the graft. In this article, the authors used bifocal distraction-compression osteosynthesis(BDCO) to create a segment of new alveolar bone and attached gingiva for the complete approximation of a wide alveolar cleft/fistula and the reconstruction of a maxillary dentoalveolar defect. Since the alveoli and gingivae on both ends of the cleft were approximated after BDCO, the need for extensive alveolar bone grafting was eliminated. It also could create new alveolar bone and gingiva for orthodontic tooth movement and implant.

A 70-year-old male with a history of diabetes mellitus, hypertension, and coronary stent insertion visited our hospital 7 days after biting his lower lip. Swelling and inflammation had worsened despite debridement and antibiotic treatment. On the 8th hospital day, fungal infection with Candida albicans and superimposed bacterial infection with Klebsiella pneumoniae were found on tissue culture. Extensive necrosis resulted in a defect of approximately 3/4 of the entire lower lip and a full-layer skin defect from the vermilion to the gingivobuccal sulcus at the right corner of the mouth. To correct drooling, incomplete lip sealing, and trismus, staged reconstruction was performed with consideration of cosmetic and functional features. The treatment process using staged reconstruction and antifungal treatment for an extensive lower lip defect caused by fungal stomatitis is described.

When oral cancer is occured, one may experience problems such as lip defect, necrosis of periodontal tissue and cervical caries caused by radiotherapy. According to ADI (Association of dental implantology), recent radiotherapy on jaw bone could be a relative contraindication of implant treatment. Due to this controversy, in most cases, treatment is done with removable dentures rather than implants. Especially, lip defect caused by an oral cancer operation have a serious repercussion on the retention of the denture. In this case report, patient with upper lip cancer had undergone resection primarily and secondary radiotherapy was done periodically. As a result, upper teeth of patient were extracted gradually and lower teeth showed very poor periodontal status. Therefore, Polident$^{(R)}$ denture adhesive cream (GlaxoSmithKline, London, England) was applied on maxillary complete denture to overcome reduced retention due to the lip defect and double crown RPD with friction pin was applied on the mandible successfully for two years.
