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.

Objectives: Electroacupuncture has the effect of recovering paralytic nerves and muscles. To treat disproportional muscles of expression with electroacupuncture, it is essential that we know the correct point of paralytic muscle. Methods: We investigated 20 cases of patients with facial palsy sequelae. We measured nasolabial angles, checked grade of muscle palsy, and tested ENoG. Results: This study showed significant correlation between nasolabial angles with these muscle groups (zygomatic group I, zygomatic group II, orbicularis oris muscle). Conclusions: Disproportional facesare fixed by muscles of expression observed in facial palsy sequelae. We can treat muscular paralysis of these muscle groups with electroacupuncture for more complete recovery.

Background: Functional closure of the orbicularis oris muscle and esthetic reconstruction of nasolabial components are impossible in patients with severely deformed premaxilla. Here, we review a surgical strategy for patients with unremedied premaxilla retrospectively. Results: Vomerine ostectomy and premaxillary setback with nasolabial repair were performed in 12 patients with bilateral cleft lip and palate. The mean age of patients was 21.7 months. The extent of ostectomy varied between 3 and 11 mm. There were no serious complications from defective perfusion to the premaxilla or the philtral flap. The follow-up period ranged from 2 to 25 months. Proper positioning of the premaxilla and satisfactory nasolabial esthetics were achieved in all patients. Conclusions: We performed nasolabial repair after premaxillary setback without jeopardizing the premaxillary segment or the philtral flap. Our surgical strategy could be recommended in poor socio-economic circumstances due to the cost effectiveness of limiting the number of surgeries.

Last week, after our receiving online journal regarding Journal of the Korean Association of Oral and Maxillofacial Surgeons, we found a recently published original article by Alawode et al., entitled "A comparative study of immediate wound healing complications following cleft lip repair using either absorbable or non-absorbable skin sutures". Although this clinical article was well written and provided a great deal of information regarding the suture materials in the cleft lip repair, I would like to add a few additional comments based on the importance of skin suture during cheiloplasties in the primary cleft lip or secondary revision patients with representative figures.

Reconstruction of the upper lateral lip subunit is challenging, and use of several classical local flaps have been previously reported. However, these methods have drawbacks such as visible scarring, anatomic distortion, and functional disability. To obtain satisfactory results, preservation of perioral function is important. We report a case of functional upper lip reconstruction after tumor resection using a reverse facial-submental artery island flap with a reinnervated anterior belly of the digastric muscle (ABDM) without sacrificing the perioral structure. A 73-year-old man presented with basal cell carcinoma on the left upper lip which was widely excised, including the orbicularis oris muscle. The remaining 4 cm × 3.5 cm defect was reconstructed using a reverse facial-submental artery island flap with ipsilateral ABDM. The motor nerve of the ABDM was sutured with the stump of the buccal branch of the ipsilateral facial nerve. The postoperative course was uneventful, and good functional and esthetic recovery were observed at 12-month follow-up. This procedure may be an alternative option for reconstruction of lateral upper lip defects.

The purpose of the present study was to investigate the difference of muscular activities of the tongue and lip muscles between anterior open-bite and normal occlusion during various function. Thirty eight subjects of 12.1-39.6 years were employed in this study : Eighteen subjects were anterior open-bites and tweenty subjects were normal occlusions. During rest position, maximum effort of lip sealing, command swallow of saliva and sucking & swallowing of juice, the electromyographic datas of the genioglossus, superior longitudinal muscle of tongue, upper and lower orbicularis oris were recorded and integrated with Medelec MS 25 electromyographic machine. Lateral cephalometric radiographs were taken on all subjects for the analysis of tongue posture and size. All data were recored and statistically processed. The findings of this study can be summerized as follows : 1. During the rest position, muscular activity of tongue was higher than that of lip muscle in open-bite, but no difference in normal occlusion group. 2. During the swallowing of juice, the activity of orbicularis oris was higher than that of genioglossus in open-bite. But the normal occusion was showed higher activity of tongue during the swallowing of juice. 3. The open-bite, compared to the normal occlusion, had higher value of tongue muscle activity during the rest position. 4. Compared to normal occlusion group, the open-bite had higher value of lip muscle activity during the sucking and swallowing of juice. 5. During the command swallow of saliva, the normal occlusion was showed harmonious swallowing pattern, but the open-bite showed much variation and disharmony in muscular contraction sequence, tended to absent of lip muscle activity. 6. At the lateral cephalometric radiographs, compared to the normal occlusion, the open-bite was showed lower tongue posture. But no difference was found in intermaxillary space. It is suggested that the open-bite, compared to the normal occlusion, had higher muscular activity of tongue during the rest position and various functions, showed lower tongue posture on the lateral cephalogram. In the development of anterior open-bite malocclusion, these factors may be an etiologic factor.

A 60-year-old woman with a history of diabetes mellitus and chronic renal failure was admitted to the hospital with severe pain in the upper lip, which began 4 days prior to admission, accompanied by a bullous lesion and suspected cellulitis in the upper lip. Immediately after admission, as the patient's general condition worsened, tests revealed a non-ST elevated myocardial infarction, septic embolism of the lung, as well as septic shock. Her upper lip suddenly presented a gangrenous and necrotic change, which the tissue and blood culture confirmed to be a Klebsiella pneumoniae infection. After a quick response, the patient's general condition improved. Subsequently, serial debridement was performed to effectively clear away the purulent discharge. While under general anesthesia, the process confirmed full-layer necrosis of the upper lip including the orbicularis oris muscle. Almost half of the entire upper lip sustained a full-layer skin and soft tissue defect, with scar contracture. Six months later, to correct the drooling and lip sealing following the defects, a scar release and an Abbe flap coverage were performed considering both functional and aesthetic aspects. The follow-up revealed a favorable corrective result of the upper lip drooling, and the patient was satisfied from a functional perspective.

Lateral facial cleft is a rare congenital craniofacial anomaly. Their incidence is about 1 in 60,000 births and early treatment with closure in layers is important. Surgical treatment must reconstruct an anatomic and functional situation which give a good esthetic result. This study reports two cases of male at 31 months and 9 months suffered from esthetic problems due to lateral displacement of the oral commisure on the right side. Surgical treatment; the mucosa is closed in with a Z-plasty to avoid intraoral band contracture, the orbicularis oris muscle is closed after interfiber reorientation, and the skin is closed with multiple Z-plasty. So we report two cases of unilateral lateral facial cleft and review of etiopathogenesis in children with lateral facial cleft.
