Distraction osteogenesis is useful treatment which the gradual separation of cut bone edges results in the generation of new bone. It is effective treatment for correcting maxillofacial deformities. Patients with cleft lip and palate usually have maxillary hypoplasia due to scarring of lip and palate. To correct these deformities, we chose to use a 2-jaw orthognathic surgery or distraction osteogenesis. But despite improvements in surgical techniques for maxillofacial deformities, postoperative stability still leaves the question of when relapse may occur. This case report describes the Relapse after treatment of maxillary hypoplasia with cleft lip and palate by Rigid External distraction system over a 2-year treatment and follow-up period. In addition, we reviewed related articles about the influence of the occlusal stability on postoperative stability in patients with cleft lip and palate correction with Distraction osteogenesis.

구순구개열은 악안면 영역의 선천기형 중 발생빈도가 가장 높으며 출생시부터 성장완료 시기까지 일관된 치료계획에 의한 종합적 진료체계가 필수적이다. 구순구개열의 개선을 위한 구개부 및 입숭? 조기 봉합 후의 반흔조직의 형성은 치열궁 협착 뿐 아니라 상악골 열성장에 의한 중안모의 함몰을 야기하며 이러한 상악골의 열성장 경향은 연령이 증가할수록 점진적으로 증가하는 성향을 보인다. 따라서, 성장잠재력을 이용한 조기의 악정형치료는 구순구개열 환자에서 반드시 필요하며, 적절한 치료 결과를 얻어내기 위하여 환자의 전후방 골격 형태 뿐 아니라, 성장 방향에 대한 고려가 필요하다. 그러나 혼합치열기의 악정형치료는 좋은 결과를 얻었다 하더라도 높은 재발 성향 및 잔여성장에 의한 악골관계의 변화가 예상되므로 장기간의 보정이 필수적이며 성장에 대한 지속적 평가가 이루어져야 할 것이다.

상악골의 열성장과 횡적 부조화, 그리고 광범위한 치조열 및 구강상악동 누공의 치료에 있어서 기존의 방법에 비해 골신장술을 사용하였을 경우, 본 증례들과 관련 문헌 고찰을 통하여, 견인량의 충분한 확보 및 회귀율의 최소화를 얻을 수 있으며, 또한 입원가료기간의 감소와 연조직 부조화의 해결을 볼 수 있어 구순구개열에 관련된 상악골 변형의 치료에 골신장술이 유용한 치료법이라 생각되어 보고한다.

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.

In cleft palate patient, characteristic of speech disorder is the resonance disorder result from velopharyngeal incompetence. Clinically VPI caused by congenital factor as congenital palatal incompetence, submucosal cleft palate, and caused by acquired factor as CNS damage, tumor, palatal palsy. The clinicians more concerned about the speech disorders after cleft palate surgery rather than language pathologist. The resonance disorder devided for hypernasality, hyponasality and nasal emission, but as a rule, hypernasality is typical phenomenon of the resonance disorder. Traditionally clinicians and language pathologists evaluated four-stage or five-stage of hypernasality by subjective assessment. Although language pathologist is well-trained, results of the language level should be different. In late 1980s, Kay Elemetrics Corp. developed nasometer that objective nasalance identified with well-trained language pathologist and originate from nasometer Tonar I and II were developed by Fletcher. Therefore objective nasalance test was possible, the nasometer used in hospital, collage and speech clinic both and home and abroad. Standardization of the cleft palate speech assessment must be settled without delay because of different character result in different language and different assessment results by dialect in same language. In our study, we provide the data base for the standardization of cleft palate speech assessment which through report of objective assessment method, speech therapy effects and problems result in interdisciplinary teamwork by nasometer use in treatment of cleft palate patient.
