The classic triad of diagnostic signs of submucosal cleft palate which may be present are: 1) bifid uvula 2) short palate with no muscle in the midline and 3) hard palate with a submucous notching defect in the posterior midline. The treatment of submucous cleft palate are V-Y push back palatorrhaphy, and superior based pharyngoplasty implant in the posterior pharynx. The best speech results were in those children operated upon in the younger age group (especially at or before 2 years of age), thus pointing up the importance of early diagnosis.

Team approach for the management of cleft lip & palate patients is very important. Plastic surgeon, oral-maxillofacial surgeon, orthodontist, otolaryngologist, and speech therapist should be included in the team. Main role of the ENT surgeon may be variable and is up to the team characteristics. Main topics of ENT surgeons' interesting fields are evaluation and management of hearing impairment due to SOM, voice disorder, and velopharyngeal incompetency due to submucous cleft palate & still remained VPI after curative palatoplasty. Basic review of anatomy & physiology related with otolaryngologic aspect of velopharyngeal system was done. Diseases related with hyponasality as well as hypernasality were discussed. Diagnostic and therapeutic methods were discussed. Proper management of hearing impairment and speech disorders are important.

This study was designed to evaluate the morphology and the position of the mandible in the complete unilateral cleft lip and palate patients, Craniofacial skeletal morphology pattern was analyzed on the lateral cephalometric radiographs of the 50 subjects of complete unilateral cleft lip and palate, the 50 normal and 50 class III, Each group was divided into child and adult sub-groups, All the data were tested statistically. The results were as follows: I, In the comparison with the normal group, complete cleft group showed smaller angular, condylar length, clockwisely rotated mandible and larger NMe/SGo(p<0.01). 2, In the comparison with the class III group, the complete cleft group showed significantly smaller angular, condylar, ramal, body length of the mandible(p<0,01). 3. As for the position of the mandibular condyle to the cranial base, the class III group was the most anterior, the normal group was the most posterior and the complete cleft group was in the middle(p<0.05). 4. In the comparison with child group, the normal adult group showed smaller mandibular angle and mandibular plane angle, but not the other two groups. And the complete cleft group and the class III group showed the similar change. The normal and class III group showed increased XiCd/XiPog, but not the complete cleft group(p<0.01).

Generally, an adult cleft lip or/and palate patient shows some amount of maxillary deficiency due to limitation of bony growth caused by heavy scars resulted from previous operations such as a cheiloplasty and/or a palatoplasty at an early child age. To solve the problem, advancement of the maxilla is usually required during orthognathic surgery. However, severe tensional force resulted from heavy scars on the palate and/or the lip, as well as the bony defect at the cleft area limited sufficient advancement of the maxillary segment and finally caused relapse of the reposed maxilla. Therefore, distraction osteogenesis of the maxilla was introduced for the successful maxillary advancement inthose kinds of patients. As both hard and soft tissues can be simultaneously and gradually extended with this technique, tensional force caused by heavy scars opposed to forward movement of the maxilla can be reduced to an extent not to develop severe relapse of the advanced maxilla. Since distraction osteogenesis of the maxilla was applied as one of standard protocols for the treatment of the patients with severe maxillary hypoplasia dueto cleft lip and/or palate, the devices for the distraction was improved to control the vectors of distraction with better and more stable. We have treated a 23-year-old male cleft patient with a severe maxillary hypoplasia using a newly developed a maxillary distraction device and a RP model for a pre-operative simulation surgery. As a result, we could successfully move the maxilla as we designed pre-operatively and also reduce much of operation time. Therefore, we report of the case to share our experience with colleagues.

Patients with cleft lip and palate usually present midfacial depression and anterior cross-bite. This dentofacial deformity has been believed due to the undergrowth of maxilla and/or the collapse of premaxilla. But, in the case that the collapsed premaxilla exists only, the reconstruction of the premaxilla has to be required for the correction of that deformity. These cases show the surgical treatment of midfacial depression and anterior cross-bite in the cleft lip and palate. After the careful diagnosis for the collapse of premaxilla, the reconstruction using distraction osteogenesis was done successfully. As a result, the anterior overbite / overjet, and facial esthetics were improved remarkably, and the occlusion was also recovered to normal state. In conclusion, the premaxillary reconstruction by distraction osteogenesis in cleft lip and palate patients is a good treatment method based on the pathophysiology.

Background: Cleft lip and palate deformity have unknown patterns of maxillofacial growth and development. The maxillofacial growth can be affected either by congenital or environmental factors such as infection and trauma. Surgical repair of cleft lip and palate may interfere the subsequent growth and development of maxillofacial region. The purpose of this study is to evaluate the characteristics of maxillofacial growth patterns in adult cleft lip and palate patients. Materials and Methods: The material for this study consisted of 17 adult male patients with cleft lip and palate. Cephalometric tracing and measurements were done by one investigator. The relationship between 17 cleft lip and palate patients and Korean norms were evaluated statistically. Results: There were statistically differences in Na. perpendicular to point A, SNA angle, effective maxillary length, maxillofacial differencial. Wit's appraisal and upper incisor to point A(p < 0.01). Pogonion to Na. perpendicular also statistically differed(p < 0.05). Other measurements didn't statistically differ. Conclusion: It was evident that in adult cleft lip and palate patients, maxilla was retruded and short. Careful cleft lip and palate repair and treatment are recommended for facilitating normal growth of maxilla.
