  • Submucous cleft palate is a relatively uncommon congenital anomaly accompanying velopharyngeal incompetence(VPI). Double opposing Z-plasty has many advantages including prolongation of soft palate, normal midfacial growth, midline scar. We analyzed postoperative results comparing with those of preoperative evaluation by several variables(nasometer, endoscopy, satisfactory scale) in 14 patients treated with double opposing Z-plasty due to submcous cleft palate. Nasalance score in Ah sound, Ma phrase, and Pa phrase decreased 20.23%, 3.25%, and 23.26% in the average, respectively. As a result, hypernasality improved significantly. Closure rate in velum evaluated by endoscopy was increased from 0.44 to 0.76. In objective satisfactory scale checked by each patient's guardian at the postoperative period, much improved in 3, improved in 6, minimally improved in 1, and no difference in 1 was reported. (n=11 patients) Double opposing B-plasty is a good surgical modality in patients accompanying VPI with submucous cleft palate or incomplete cleft palate and will be used more usefully and widely.

  • Il Woong Cleft lip and palate foundation was founded in 1968 by Professor emeritus Byoung-Il Min. Since then the foundation has operated numerous cleft lip and palate patients not only in Korea but also in under-developed countries such as Vietnam, China, and Cambodia. In December 2005, the foundation was allowed as an incorporated association by Ministry of Foreign affairs and Trade, so that it could have official status. From March 6th 2009 to March 14th 2009, we conductp,d charity cleft lip and palate operations of 23 patients in areas of Deozhou, China. Hereby we present the results of operations.

  • The purpose of this survey was to obtain an overall view of the status of cleft lip and palate management in Oral and Maxillofacial Surgery(OMFS) in Korea. Korea Cleft lip and Palate Association conducted mailed survey which was composed of 29 questions conceming pre-operative and post-operative management in CLP surgery and completed by 58 training hospital. Of 58 questionnaires sent, 23 were returned(response rate of 40%). Authors compared this results with those of other similar surneys, which reveal much difference between OMFS and Plastic Surgery(PS) in CLP treatment. In OMFS, many surgeons were in favor of presugical orthopaedics than lip adhesion to manage protruded premaxilla. It reflects interdisciplinary team approach between OMFS and orthodontic department reduces the need of lip adhesion through presurgical orthopaedics. Timing of palatal surgery was later than that of PS, which reflects concern for an impediment of maxillaty growth. To our knowledge, this survey may be the first on organization and management for cleft patient in OMFS in Korea.

  • Purpose: The oral teratoma is found approximately in live birth at the rate from 1 : 35,000 to 1 : 200,000. In a review of literature 16 cases of midline teratoma with cleft palate were reported. We report a case of congenital palatal teratoma with cleft palate in a 1-year-old girl. Methods: A 1-year-old girl was admitted our institution for the closure of cleft palate. On the intraoperative findings there was $4{\times}1{\times}0.5cm$ sized hairy soft mass at the midline and complete cleft palate. We did incisional biopsy intraoperatively and its pathology revealed heterotopic brain tissue. The excision of remaining mass and palatoplasty with Sommerlad's method were performed. The final pathology of the mass was mature cystic teratoma. Results: After the operation there were neither recurrence nor oronasal regurgitation. Conclusion: We report for one patient with congenital palatal teratoma associated with cleft palate and obtained an excellent result.

  • Untreated adult or elderly cleft lip and palate patients are rarely seen, but studies on delayed primary palatal closure have been performed in the less developed Asian and African countries, where access to medical care is difficult. A 64-year-old woman visited our clinic with untreated cleft palate with a 40×20-mm-wide defect in the medial palate. Two-flap palatoplasty under general anesthesia was performed to close the cleft palate. After 1 month, the result was favorable without any complications including oronasal fistula. Cleft palate primary repair in an elderly patient is rare and has some surgical problems that are associated with a wide range of defects, but good results can be obtained if surgery is performed well with appropriate considerations.

  • A 7-month-old, weak female dachshund dog which had signs of cough and sneezing while eating was admitted. This case was diagnosed as cleft hard palate by the physical and blood examination. After aseptic surgical preparation, a surgical method utilizing mucoperiosteal and buccal flap technique, in which accurate apposition and secure closure was very important, was used successfully. The defect of hard palate was healed completely on 10 days after surgery without any other complication.

  • Introduction: A cleft palate is a common birth defect in humans with an incidence of 1/500 to 1/1,000 births. It appears to be caused by multiple genetic and environmental factors during palatogenesis. Many molecules are involved in palate formation but the biological mechanisms underlying the normal palate formation and cleft palate are unclear. Accumulating evidence suggests that transforming growth factor $\beta$/bone morphogenetic proteins (TGF-$\beta$/BMP) family members mediate the epithelial-mesenchymal interactions during palate formation. However, their roles in palatal morphogenesis are not completely understood. Materials and Methods: To understand the roles of TGF-$\beta$/BMP signaling in vivo during palatogenesis, mice with a palatal mesenchyme- specific deletion of Smad4, a key intracellular mediator of TGF-$\beta$/BMP signaling, were generated and analyzed using the Osr2Ires-Cre mice. Results: The mutant mice were alive at the time of birth with open eyelids and complete cleft palate but died within 24 hours after birth. In skeletal preparation, the horizontal processes of the palatine bones in mutants were not formed and resulted in a complete cleft palate. At E13.5, the palatal shelves of the mutants were growing as normally as those of theirwild type littermates. However, the palatal shelves of the mutants were not elevated at E14.5 in contrast to the elevated palatal shelves of the wild type mice. At E15.5, the palatal shelves of the mutants were elevated over the tongue but did not come in contact with each other, resulting in a cleft palate. Conclusion: These results suggest that mesenchymal Smad4 mediated signaling is essential for the growth of palatal processes and suggests that TGF-$\beta$/BMP family members are essential regulators during palate development.

  • The aim of present study was to assess the thickness of masticatory mucosa on the hard palate and tuberosity as a potential donor site for mucogingival surgery. Thickness measurement was performed in 30 dental college students who are periodontally healthy, with a recently developed, ultrasonic device(SDM). The mean age of study subjects was 23.7(range 21-29) years old and the subjects were composed of 18 males and 12 females. Eighteen standard measurement points were defined on the hard palate, located on 3 lines which ran at different distances parallel to the gingival margin. Six positions were designated on each of these 3 lines between the level of the canine and the second molar. On the tuberosity, 6 standard measurement points were defined, located on 2 lines running parallel to the gingival margin at different distances. Data were analyzed to determine differences in gender, between different positions, and between lines, by an analysis of variance. The results showed that the mucosa of the tuberosity was significantly thicker than that of the hard palate region. Gender did not influence the thickness of masticatory mucosa, either on the hard palate or the tuberosity. On the hard palate, mucosa thickness increased as the distance from the marginal gingiva increased. The mucosa over the palatal root of the maxillary first molar was significantly thinner than that at all other positions on the hard palate. Measurement error at palate was 0.25mm, at tuberosity 0.51mm. No difference in the thickness of masticatory mucosa on palate and tuberosity was found between men and women. On the hard palate, soft tissue thickness progressively increased in sites further from the gingival margin. Therefore, we may harvest more thicker graft on the tuberosity that has more masticatory mucosa thickness than hard palate, however the width may not be sufficient for using.

  • Submucosal type cleft palate is subdivision of cleft palate. Because of late detection, the treatment - for example, the operation or the speech therapy - for the submucosal type cleft palate patient usually late. In this study, we want to find the objective characteristics of submucosal type cleft palate patient, comparing with the normal and the complete cleft palate patient. Experimental groups are 10 submucosal type cleft palate patients who got the operation in our hospital, 10 complete cleft palate patients. And, 10 normals as control group. The sentence patterns using in this study is simple 5 vowels. Using CSL program we evaluate the Formant, Bandwidth. We analized the spectral characteristics of speech signals of 3 groups, before and after the operation.

  • The velopharyngeal dysfunction usually occurs in patients with previous operation of the cleft palate or with submucosal cleft palate. In case of velopharyngeal dysfunction without cleft palate, no study has been made when it comes to operative method and postoperative results. Here, we would like to present the operative methods and the postoperative results with the cases we've experienced. This study is based on seven cases of velopharyngeal dysfunction without cleft palate from 1999 to 2004. Analysis of age, sex, etiology, operative methods, satisfaction rate and speech evaluation was done. The patients were 3 males and 4 females, with an age ranged from 10 to 28 at the time of surgery. The follow-up period was more than six months. One case had bifid uvula, another had atypical anomaly in palate, and five cases had no anatomical abnormality. The palatal lengthening was done on one patient, the levator muscle repositioning on another patient and to the rest of them, the superiorly based posterior pharyngeal flap was done. It was difficult to determine the etiology of the velopharyngeal dysfunction without cleft palate. The speech improvement and the satisfaction rate of the patients and parents were diverse. Although the authors had a problem with statistical analysis between the operative age and the speech improvement, it was reasonable to perform a surgical operation because postoperative speech improvement was observed in most cases regardless of age. There is little statistical correlation, but significantly higher outcomes were observed in palatal lengthening and levator muscle repositioning than in pharyngeal flap.
