This study was conducted to determine the electromyographic features in the perioral muscles of class II division 1 malocclusion with incompetent lips, and to grope the correlation between its activities and craniofacial morphology. Tn this study, 14 subjects with class II division 1 malocclusion with incompetent lips(mean age of 20.5 years) and 20 subjects with normal occlusion(mean age of 23.9 years) were investigated. Electromyographic data were recorded from orbicularis oris, mentalis, buccinator and suprahyoid muscles durig rest lip posture, lip position at sealing, maximum sealing, maximal blowing, maximal biting, sipping milk, sipping and swallowing milk, chewing gum, masticating almond, swallowing almond and phonation utilizing the Medelec MS-25 electromyographic apparatus. Lateral cephalometric radiographs were taken with the mandible in intercuspal position on all subjects. All data were recorded statistically processed. The findings of this study can be summerized as follows : 1. In class II division 1 malocclusion with incompetent lips, the overall augmentations of perioral muscle activities during various functionel movements set for lip sealing were manifested and particular swelling in mentalis activity at rest was detected. 2. On the other hand remarkable diminution of upper lip acitivities at lip sealing movements was drawn. 3. In Class II division 1 malocclusion with incompetent lips, negative correlations existed between the diversity of upper lip activities and upper incisor position and overjet as well in contrast to positive correlations in the lower lip. 4. It was suggested that the abnormal function of lower lip and mentalis muscle contributed somewhat the revelation of the characteristics of Class II division 1 malocclusion.

Purpose: The purpose of this study is to develop three-dimensional computerized anthropometry(3DCA) and to compare its reliability and accuracy 3DCA with manual anthropometry(MA) for measurement of lips and nasal deformities in unilateral cleft lips and palate(UCLP) patients. Methods: Samples were consisted of six UCLP patients whose facial plaster models were available immediately before and 3 months after the cleft lip surgery. MA of the facial plaster models was carried out using an electronic caliper. In 3DCA, three-dimensional auto-measuring program was used to digitize landmarks and to measure three-dimensional virtual facial models (3DVFM), which was generated with a laser scanner and 3D virtual modeling program. Intraclass correlation coefficients(ICC) were calculated to evaluate reliability and reproducibility of the variables in both methods, and Wilcoxon's signed rank test was done to investigate the difference in values of the same variables of facial models of each patient between two methods. Results: All ICC values were higher than 0.8, so both methods could be considered reliable. Although most variables showed statistical differences between two methods(p<0.05), differences between mean values were very small and could be considered not significant in clinical situation. Conclusion: In clinical situation, 3DCA can be an objective, reliable and accurate tool for evaluation of lips and nasal deformities in the cleft patients.

Treacher Collins syndrome is inherited as an autosomal dominant trait with variable penetrance. It shows a marked variability even in the same family. This syndrome is developmental defect affecting the branchial arches. It is not usually associated with acute respiratory distress, but has symptoms of microtia, hypoplastic zygomatic bones, hypoplastic mandibular rami, and bilateral coloboma. It usually requires an emergency operation immediately after the birth. We experienced an infant with Treacher Collins syndrome who showed retrognathia, glossoptosis, microtia, and cleft palate. Intermittent cyanosis, depression of the chest, respiratory difficulty associated with airway obstruction, and swallowing difficulty were also observed. To relieve severe upper airway obstruction caused by retrognathia and glossoptosis, we simultaneously performed tongue-lip adhesion and subperiosteal release of the floor of the mouth. The respiratory and swallowing difficulties were relieved and the tongue repositioned anteriorly. We report the present case with a review of the literature.

Purpose: Correction of cleft lip nose deformity (CLND) in adulthood is different from one in childhood. Usually correction of CLND is final surgery for adult patient who has cleft lip, so many things have to be considered for correction. Of course, it is different from common rhinoplasty, either. The adult patients can be corrected by complete rhinoplasty with various techniques. To recognize how rhinoplasty techniques was used for correction of CLND, authors analyzed detailed techniques which were selected in the adult patients for 10 years and reviewed comprehensive operation. Methods: A retrospective review was conducted involving 64 patients with CLND who underwent surgery and aged after 14 years at operation between 2001 and 2010. Detailed techniques were investigated by medical record review and classified according to incision, septoplasty, osteotomies, correction of vault, tip plasty and etc. Results: Except one, all patients were performed open rhinoplasty. 49 patients were performed septoplasty. 33 patients were performed complete rhinoplasty with osteotomies. Hump nose correction was performed for 10 patients. Dorsal augmentation was performed for 8 patients. And all patients were performed tip plasty. Tip plasty using suture technique was performed for 58 patients and graft was performed for 48 patients. Conclusion: Correction of CLND in adult is one of the most challenging and varied operation of plastic surgery. In this study, the majority of patients were performed complicated and delicated procedures. It seems to be because patient's demand level has been elevated and rhinoplasty procedures have been advanced. This study may help to planning of CLND correction.

Purpose: In the treatment of the unilateral cleft lip nasal deformities, the correction of the low-nostril height and short-columella are very difficult problems. We report the treatment outcomes of web uni-limb Z-plasty used for correction of unilateral cleft lip nasal deformities by using photographic analysis. Methods: A total of 36 patients with unilateral cleft lip nasal deformities were enrolled in this study, who underwent web uni-limb Z-plasty and were followed up for at least 6 months. First, a triangular flap was made on the medial side of alar-columella web. The nostril apex of cleft side was corrected to a higher point compared to noncleft side by 2 mm. The flap was transposed into the defect of the vestibule. To reduce the bulging of the flap, horizontal cinching sutures were added. Postoperative outcomes were evaluated by using photographic analysis. 2 indices and 1 angle were measured on their photographs taken before and after the surgery. Symmetry was also evaluated by means of the noncleft side to cleft side index. For anthropologic assessment, observers described postoperative outcomes, using Ordinary Scale Method. Results: The postoperative values obtained in photographic analysis improved compared to preoperative ones. More improving anthropologic assessment was shown in post-than pre-operative. Conclusion: Although, further long term follow up is needed, we found this technique to be an effective procedure to the symmetry of nostril apex level and the lengthening of columella in the unilateral cleft lip nasal deformities.

Purpose: In the correction of cleft lip, there have been various methods to minimize recurrence of the nasal deformity after primary nasal surgery. After cheiloplasty and primary nasal surgery, we tried to elongate the columella of the cleft side, to stretch the vestibular lining of cleft side, and to elevate the alar cartilage of the cleft side with a molding prong. Methods: We had fifteen cleft lip patients; 12 unilateral cases(6.3-8.2 months), and 3 bilateral cases(3 - 7.5 months). Immediately after primary repair of the cleft lip, the toboggan shaped molding prong was located to deep inside of vestibular web of the cleft side. It was persistently suspended by a silicone tube which was connected to the prong and the frontal scalp. The results were analyzed with $Photoshop^{(R)}$ photogrammetrically for 6 - 48 months with on average of 20.6 months. We measured the proportion index of columellar length-interalar distance for three times(preoperation, immediate postoperation, and postoperation) on the nasal base views. Results: In unilateral, the index had a significant increase statistically between preoperation(10.73) and immediate postoperation(23.96). It is supposed that columellar length was reconstructed to 105.80% of normal side. But, it was decreased to maintain 87.7% of normal side in postoperation(20.54). The results were similar in bilateral. The linear scars by suture penetrating nose skin were not discernable. Conclusion: In summary, placement of the molding prong could elongate the reconstructed columella with some relapse postoperatively.

To evaluate the stability after orthognathic surgery in cleft lip and palate patients using rigid fixation, 20 patients underwent primary repair in childhood and later developed a jaw deformity and malocclusion that required orthognathic surgery were reviewed. Two groups, one of 10 patients performed Le Fort I osteotomy with sagittal split ramus osteotomy and one of 10 patients with sagittal split ramus osteotomy of the mandible, were evaluated. Each group had unilateral cleft only and all alveolar cleft sites had been grafted with autogeneous bone before the orthognathic surgery. The amount of surgical movement and relapse were compared in both horizontal and vertical dimensions. Two-jaw surgery group was more stable than mandibular surgery only group in mandibular position (p< 0.05). Statistically significant relapse was observed in mandibular skeletal point in mandibular surgery group (p<0.05). There was no statistically significant relapse in the skeletal point of two-jaw surgery group. However, the correlation between the horizontal surgical movement and relapse was detected (r = 0.88). This correlation indicates the need of overcorrection. The presence of scar tissues and relatively deficient maxillary bone could be attributed to this close relation between the surgical change and relapse.
