Purpose: Cleft lip and palate is one of the most frequent hereditary deformities of the maxillofacial region which can arise in facial and jaw abnormalities as well as malocclusion and speech problems. In particular, unilateral cleft lip and palate is characterized by midface deformity resulting in maxillary anterior nasal septal deviation and nasal deformity. The aim of this study is to analyze the facial deformity of untreated unilateral cleft lip patients for contribution to primary cheiloplasty. Methods: Thirty-three patients with unilateral cleft lip and palate were impressioned before operation and facial casts were made. The casts were classified into complete cleft lip and incomplete cleft lip groups and each group were classified into affected side and normal side. Anthropometric reference points and lines were setted up and analysis between points and lines were made. Results and Conclusion: The obtained results were as follows: 1. The intercanthal width had no significant difference between the incomplete and complete cleft lip groups. 2. Cleft width and alar base width were greater in the complete group, and nasal tip protrusion was greater in the incomplete group. 3. Involved alar width and nostril width were greater in the complete group and in both complete and incomplete groups, involved alar width and nostril width were greater than the non-involved side. 4. The lateral deviation of the subnasale was greater in the complete group in both involved and non-involved sides. 5. The nasal laterale was placed inferiorly in both cleft groups. 6. The subnasale was deviated to the non-involved side in both cleft groups. 7. The nose tip was deviated to the non-involved side in both cleft groups and had greater lateral deviation in the complete cleft group. 8. The midpoint of cupid's bow had no vertical difference between complete and incomplete groups, but had a greater lateral deviation in the complete group. 9. In the complete cleft group, correlation between differences in cleft width and nostril width and columella height difference were obtained.

Background: The cause of maxillary growth restriction in patients with cleft lip and palate remains controversial. While studies have investigated the effects surgical technique and timing have on maxillary growth, few focus on patients with isolated cleft palate (ICP). The purpose of this study was to determine the impact palate repair and its associated complications may have on maxillary growth. Methods: A retrospective chart review of ICP patients who underwent palatoplasty from 1962 to 1999 at Akron Children's Hospital was performed. Patient demographics, Veau type, age at primary repair, closure technique, presence of fistula or velopharyngeal insufficiency (VPI), number of palatal operations, maxillary hypoplasia (MH) frequency, and follow-up were recorded. Exclusion criteria included patients with cleft lip, submucous cleft, or syndromes. Results: Twenty-nine non-syndromic ICP patients were identified; 62% (n = 18) had Veau type 1 and 38% (n = 11) had Veau type 2. All patients underwent 2-flap or Furlow palatoplasty with mobilization of mucoperiosteal flaps. Vomerine flaps were used in all Veau 2 cleft palate closures. Palatoplasty was performed at a mean age of 19.9 ± 8.2 months. Average follow-up was 209 ± 66.5 months. The rate of VPI was 59% (n = 17) and the rate of oronasal fistula was 14% (n = 4). Conclusions: There was a low incidence of MH despite complications after initial palate closure. Our results seem to suggest that age at palate closure, type of cleft palate, and type of surgical technique may not be associated with MH. Additionally, subsequent procedures and complications after primary palatoplasty such as VPI and palatal fistula may not restrict maxillary growth.

Objective: This study is performed to investigate the trend of health care (HC) utilization among cleft lip and/or palate (CL/P) during 2007-2016 by using data from the Korean National Health Insurance Service (KNHIS). Methods: The KNHIS data were reorganized to count a specific patient only once for a specific year. Cleft type (cleft lip [CL], cleft palate [CP], and cleft lip and palate [CLP]), sex, and age at HC utilization were investigated. The study period was divided into the first half (2007-2011) and the last half (2012-2016). The utilization number and rate per 1,000 population were calculated for the total population and for new-born patients. Independent t-test and one-way analysis of variance were used for statistical analyses. Results: The total CL/P population (n = 48,707) comprised 19.2% CLP, 35.5% CL, and 45.3% CP (CLP < CL < CP; p < 0.001). Their HC utilization rate increased from 0.066 in 2007 to 0.118 in 2016. The new-born patient population (n = 7,617) comprised 18.6% CLP, 30.4% CL, and 51.0% CP (CLP < CL < CP; p < 0.001). Their HC utilization rate increased from 1.12 in 2007 to 1.74 in 2016. An examination of the utilization number and rate among new-born patients revealed CP exhibited a female-dominant pattern (all p < 0.01), while CL and CLP exhibited a male-dominant pattern (all p < 0.01). However, utilization number showed no difference by sex and cleft type between 2007-2011 and 2012-2016. Conclusions: These results might serve as a guideline for HC utilization among patients with CL/P.

본 증례에서는 2명의 불완전, 그리고 완전구순열 환자를 Delaire의 개념에 의하여 수술을 시행 하였다. 불완전 구순열 교정은 코 교정 후 좌우 비대칭을 해소할 수 있었으나 완전구순구개열의 환아에서는 코의 비대칭성을 회복하기 위해 동시 수술을 시행하였으나 좌우 비대칭성은 수술 후에도 관찰할 수 있었다. 본 증례의 경우 환자의 경제적 그리고 사회적 이유로 인해 수술이 지연된 환자로 수술에 난이도는 비교적 높지 않았던 경우로 비강전정부위와 비익부위, 그리고 구륜근 등의 피부 하방에 비정상적으로 배열된 근육의 박리와 재위치를 이루어주었던 경우였다. 술 후 평가를 위한, 심미, 발음, 기능과 정서적 발달 정도를 검사하여야 하나 지리적 관계로 재평가가 어려운 점이 예상된다.

A cephalometric radiographic cross sectional comparative study was undertaken to investigate craniofacial growth in cleft lip and palate individuals. The material for this study consisted of 43 subjects with operated cleft lip and palate.(29 males, 14 females). The range of age was from 6 years to 12 years. The roentgenocephalometric values of cleft individuals were compared with values of normal individuals reported by Lee. The following conclusions were obtained; 1) The pattern of cranial base of the cleft subjects was almost the same as that previously reported for the normal individuals. 2) Anterio-posterior length of the mandible did not show any significant difference but in the cleft subjects, that of the males was larger than that of the females. 3) The maxilla of the cleft subjects was very retruded and showed very concave profile. 4) Gonial angle of the cleft subjects was very high, especially in the female clefts. 5) The height of ramus was very poor in the cleft subjects. 6) The facial length was almost the same, but the facial depth of the cleft subjects was smaller than that of the normal individuals. 7) Maxillary and mandibular incisors were severely retroclined. 8) The range of values in the cleft subjects was very variable and the female clefts showed more distured growth than the male clefts.
