The mean age at surgical correction was 6.5 years, and the average follow-up was 4.5 years. Direct measurements were made on panoramic radiographs. The condyle-ramus length was expressed as a percentage change comparing the constructed with the normal side. During the first 2 postoperative years, there was either no change or a slight decrease in the length of the rib graft. After 2 years, however, the costochondral graft elongated at a slow, irregular rate. The mode change was 11 percent over the postoperative study period. In four patients who exhibited rapid growth of the normal condyleramus (greater than the mean change of 0.94 cm), the constructed side failed to keep pace. In another group of four patients who exhibited moderate elongation of the normal side, the grafted side grew commensurately or demonstrated greater than normal percentage change in length. There was no correlation between the initial size of the costochondral graft, age at time of operation, or presenting type of mandibular deformity. These findings are discussed in terms of the intrinsic growth and the functional matrix theories of mandibular development.","PeriodicalId":76622,"journal":{"name":"The Cleft palate journal","volume":"26 4","pages":"312-7"},"PeriodicalIF":0.0,"publicationDate":"1989-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13943245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"A jointed fan-type expander: a newly designed expansion appliance for the upper dental arch of patients with cleft lip and/or palate.","authors":"A Suzuki, Y Takahama","doi":"","DOIUrl":"","url":null,"abstract":"Most patients with repaired cleft lip and/or palate have malocclusion and show various forms of occlusal discrepancy between the upper and lower dentition. In unilateral clefts, the teeth in the collapsed small segment are usually in lingual crossbite, although in most cases they are in normal buccolingual occlusal relation in the molar region. Expansion appliances should fulfill the following functions: the application of expansion force to the alveolar bone of the maxillary complex without buccal tipping of the teeth (to obtain the differential segmental movement); force to the lateral segments of the maxilla without their distortion; and expansion of the smaller segment without creating posterior crossbite. Unfortunately, many appliances do not satisfy these functions. A new fan-type expansion appliance has been designed by the authors to solve these problems. This appliance consists of three parts, as follow: an expansion screw; four bands (anchorage); and a joint connecting both buccal segments. The expansion screw is set in a direction tangent to the curve drawn by the intended fan-type movement of the collapsed small segment. The joint converts the expansion force from parallel to an arched direction.","PeriodicalId":76622,"journal":{"name":"The Cleft palate journal","volume":"26 3","pages":"239-41; discussion 241"},"PeriodicalIF":0.0,"publicationDate":"1989-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13809731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Pathogenesis of cleft palate in Treacher Collins, Nager, and Miller syndromes.","authors":"K K Sulik, S J Smiley, T A Turvey, H S Speight, M C Johnston","doi":"","DOIUrl":"","url":null,"abstract":"Abnormalities of the secondary palate were studied in an animal model in which features of Treacher Collins syndrome (TCS) and Nager or Miller syndromes (both of which are facially similar to Treacher Collins, but include limb malformations) were induced by acute maternal exposure to 13-cis-retinoic acid (13-cis-RA, isotretinoin, Accutane). Previous work in our laboratory has illustrated that excessive cell death in the proximal aspect of the maxillary and mandibular prominences of the first visceral arch and in the apical ectodermal ridge of the limb bud probably accounts for the characteristic craniofacial and limb abnormalities observed (Sulik et al, 1987; Sulik and Dehart, 1988). The current study shows that maternal treatment with 400 mg per kilogram 13-cis-RA at 8 days 14 hours (8d14hr) or 9d6hr post fertilization results in abnormalities of the secondary palate that vary in incidence and severity. Following the earlier treatment time, 82 percent (68 of 74) of the 18d fetuses were affected, with, severely hypoplastic, unfused palatal shelves present in 34 percent (25 of 74). The less severely affected fetuses had malformations that involved primarily the posterior aspect of the palatal shelves. This malformation (foreshortening of the posterior portion of the palate) constituted the major developmental alteration that resulted from treatment at the later time, at which time a 52 percent (26 of 50) malformation incidence was seen. The change in pattern of malformations with treatment time is consistent with the changing pattern of programmed cell death, which was observed to occur in the first visceral arch.","PeriodicalId":76622,"journal":{"name":"The Cleft palate journal","volume":"26 3","pages":"209-16; discussion 216"},"PeriodicalIF":0.0,"publicationDate":"1989-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13898769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
