  • 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.

  • Background No consensus exists on the optimal treatment protocol for orofacial clefts or the optimal timing of cleft palate closure. This study investigated factors influencing speech outcomes after two-stage palate repair in adults with a non-syndromal complete unilateral cleft lip and palate (UCLP). Methods This was a retrospective analysis of adult patients with a UCLP who underwent two-stage palate closure and were treated at our tertiary cleft centre. Patients ${\geq}17$ years of age were invited for a final speech assessment. Their medical history was obtained from their medical files, and speech outcomes were assessed by a speech pathologist during the follow-up consultation. Results Forty-eight patients were included in the analysis, with a mean age of 21 years (standard deviation, 3.4 years). Their mean age at the time of hard and soft palate closure was 3 years and 8.0 months, respectively. In 40% of the patients, a pharyngoplasty was performed. On a 5-point intelligibility scale, 84.4% received a score of 1 or 2; meaning that their speech was intelligible. We observed a significant correlation between intelligibility scores and the incidence of articulation errors (P<0.001). In total, 36% showed mild to moderate hypernasality during the speech assessment, and 11%-17% of the patients exhibited increased nasalance scores, assessed through nasometry. Conclusions The present study describes long-term speech outcomes after two-stage palatoplasty with hard palate closure at a mean age of 3 years old. We observed moderate long-term intelligibility scores, a relatively high incidence of persistent hypernasality, and a high pharyngoplasty incidence.

  • Cleft lip and/or palate(CLP) is the most common congenital deformity in the craniofacial region. For a practical public health system for these patients it is necessary to have an understanding on the prevalence of CLP. However, it was difficult to estimate the exact number of CLP patients due to problems in sample selection, higher miscarriage and still birth rate, difficulty in classification, and adoptions to foreign countries. Therefore this study was to estimate the prevalence of CLP and the rate of orthodontic treatment, which is usually necessary in cleft lip and/or palate patients. The samples consisted of 218,322 Korean male adults from Seoul, Kwangju, Taegu and Pusan, all born in 1979. The screening method for recognizing the CLP patients was proceeded in steps and the results are as follows. 1. The prevalence of cleft lip and/or palate in Korean male adults born in 1979 was 0.65 out of the 1000 samples. 2. In the anteroposterior aspect of the 1000 samples, the prevalence of cleft lip, cleft lip and palate, and cleft palate was 0.26, 0.36 and 0.03 respectively. 3. In the transverse aspect of the 1000 samples, the prevalence of left, right and bilateral cleft was 0.35, 0.16, 0.12 respectively. The cleft in the left showed a much higher prevalence than in the rirht, while bilateral cleft showed a lower prevalence than unilateral cleft. 4. The orthodontic treatment rate of Korean male adults among cleft lip and/or palate Patients was $35\%$, and it was in the order of cleft lip and Palate, cleft lip, and cleft Palate, being $67\%,\;29\%\;and\;29\%$ respectively. The orthodontic treatment rate in patients with the more severe cleft lip and palate was higher than in patients solely having cleft lip or cleft palate.

  • The purpose of this study is to investigate possible correlation between the dental anomalies and site of cleft in cleft lip and palate. In this study, 142 patients who had cleft lip and/or cleft palate were examined. The results are as follows. 1. The incidence of missing tooth was high in the permanent dentition as compared to the incidence in the deciduous dentition. 2. There was not much difference of incidence of supernumerary tooth between deciduous and permanent dentition in the group of patients who had cleft lip and jaw with or without cleft palate. 3. In the group of patients who had cleft lip and jaw with or without cleft palate, the frequency of incidence of cleft sides was higer in unilateral than bilateral cases. And, incidence of left sides was higher than right sides. 4. The type of cleft between central incisor and canine with missing lateral incisor was most frequent in permanent dentition and the type of cleft between central and lateral incisor was most frequent in deciduous dentition. 5. The type of cleft associated with tooth position in deciduous dentition was not almost the same in the succeeding permanent dentition.

  • The author observed morphological change in palate development of rat embryo after irradiation of x-ray on the one side of the duplex uterus. The time-matings occured between 6 p.m. and 8 p.m. and all females with copulation plugs at 8 a.m. were isolated and properly marked for evidence of copulation. The lower left abdomen of mothers were exposed to x-radiation on the 7 1/2th, 9 1/2th, 11 1/2th day of gestation, respectively 150, 250, 350, 500rads. At 18 1/2th day of post-conception, the pregnant females were dissected and the contents of the two uteri examined. The translucent sample by Alizarin red S stain were prepared. The results were as follows; 1. The result that groups irradiated by 250rads and 350rads made marked difference in comparison with the control group suggests the x-ray to be a inducing factor of cleft palate. 2. At 11 1/2th day of gestation, incidence of cleft palate induced by x-irradiation was highest. 3. Mortality showed the highest frequency at 7 1/2th day of gestation and tended to decrease in according to increasing of age. 4. Morphology of cleft palate induced by x-irradiation showed similarity in comparison with those induced by other factors having reported ever.

  • The purpose of this study was to evaluate the frequency of congenital missing teeth and supernumerary teeth in cleft patients. The subjects were divided into bilateral cleft lip and palate(BCLP), unilateral cleft lip and palate(UCLP) and cleft palate alone(CP alone) groups. 97 cleft patients(BCLP 15, UCLP 70, CP alone 12) between 6-20 years old were evaluated. Panorama film, Orthodontic chart and initial intraoral photogram were employed for this research. The obtained results were as follows. 1. The incidence of congenital missing teeth in total cleft samples was $57.7\%$, and the incidence of supernumerary teeth was $26.8\%$. Each incidence was higher than non-cleft. 2. The incidence of congenital missing teeth was the highest in BCLP and the lowest in CP alone. 3. The number of congenital missing teeth per perso was usually one, and the frequency was higher in the maxillary lateral incisors$(67.8\%)$, and maxillary second premolar$(14.9\%)$ than other teeth. 4. Most of tooth number anomalies in cleft patients were found in maxilla, especially adjacent region to the cleft site.

  • Several kinds of surgical methods have been used to treat the submucous cleft palate with hypernasality. The purpose of this study was to evaluate the double opposing Z-plasty which is one of the newly established surgical methods by Dr. Furlow in three cases of submucous cleft palate with hypernasality operated in this department. There were a number of advantage of double opposing Z-plasty. The surgery is adaptable for use in early patient. Midfacial growth retardation and complication were not seen in all cases. Hypernasality was improved subjectively. Using the nasometer, the nasalance score of the postoperative period was compared with that of before surgery, much improvement were noted in 'Ah', 'PaPa'. And fiberoptic endoscope was used to evaluate the velopharyngeal closure pattern. Velopharyngeal closure pattern with velum was improved dramatically, Double opposing Z-plasty seem to be a good procedure for the treatment of submucous cleft palate with hypernasality.
