  • Craniofacial cleft is a rare disease, and has multiple variations with a wide spectrum of severity. Among several classification systems of craniofacial clefts, the Tessier classification is the most widely used because of its simplicity and treatment-oriented approach. We report the case of a Tessier number 3 cleft with wide soft tissue and skeletal defect that resulted in direct communication among the orbital, maxillary sinus, nasal, and oral cavities. We performed soft tissue reconstruction using the straight-line advanced release technique that was devised for unilateral cleft lip repair. The extension of the lateral mucosal and medial mucosal flaps, the turn over flap from the outward turning lower eyelid, and wide dissection around the orbicularis oris muscle enabled successful soft tissue reconstruction without complications. Through this case, we have proved that the straight-line advanced release technique can be applied to severe craniofacial cleft repair as well as unilateral cleft lip repair.

  • A national wide survey was conducted to assess a present condition in management of cleft and craniofacial anomaly patients and training program of orthodontic residents in Korea. A questionnaire consisting of four categories and 19 question items was distributed to 131 residents of department of orthodontics of eleven dental university hospitals and nine medical university hospitals. The results were as follows:(1) 77.1% of residents are participating in treatment of cleft and craniofacial anomaly patients.(2) Only 47.3% of residents are willing to treat cleft and craniofacial anomaly patients in their future practice.(3) 64.9% of residents responded that they are currently treating one to ten cleft and craniofacial anomaly patients per resident.(4) Most university hospitals offer training programs focusing on embryopathogenesis, growth, and treatment, but training programs about speech and hearing, genetics, and psychosocial development are inadequate.(5) 37.4% of residents are willing to participate in fellowship program for cleft and craniofacial anomaly after finishing the training. Based on the results of this survey, the residents need motivation regarding treatment of cleft and craniofacial anomaly patients, and the educational programs need to be reinforced and reconstructed so that standardization among hospitals can be achieved.

  • The prevalence of craniofacial cleft is reported to be 10-34 / 100,000 live birth of human. This case report describes the characteristics of the Tessier classification number 0, 5, 7, and 14 craniofacial cleft patients. Given the rarity and unique nature of the clinical expression of each of the craniofacial clefts, the treatment plans can not be standardized but must be based on the individual assessment of each case.

  • Cleft lip and/or palate are common birth defects in humans and the causes including multiple genetic and environmental factors are complex. Combinations of genetic, biochemical, and embryological approaches in the laboratory mice are used to investigate the molecular mechanisms underlying normal craniofacial development and the congenital craniofacial malformations including cleft lip and/or palate. Both forward and reverse genetic approaches are used. The forward genetic approach involves identification of causative genes and molecular pathways disrupted by uncharacterized mutations that cause craniofacial malformations including cleft lip and/or cleft palate. The reverse genetic approach involves generation and analyses of mice carrying null or conditional mutations using the Cre-loxP mediated gene targeting techniques.

  • Objective: To investigate the distribution, side involvement, phenotype, and associated anomalies of Korean patients with craniofacial clefts (CFC). Methods: The samples consisted of 38 CFC patients, who were treated at Seoul National University Dental Hospital during 1998-2018. The Tessier cleft type, sex, side involvement, phenotype, and associated anomalies were investigated using non-parametric statistical analysis. Results: The three most common types were #7 cleft, followed by #0 cleft and #14 cleft. There was no difference between the frequency of male and female. Patients with #0 cleft exhibited nasal deformity, bony defect, and missing teeth in the premaxilla, midline cleft lip, and eye problems. A patient with #3 cleft (unilateral type) exhibited bilateral cleft lip and alveolus. All patients with #4 cleft were the bilateral type, including a combination of #3 and #4 clefts, and had multiple missing teeth. A patient with #5 cleft (unilateral type) had a posterior openbite. In patients with #7 cleft, the unilateral type was more prevalent than the bilateral type (87.0% vs. 13.0%, p < 0.001). Sixteen patients showed hemifacial microsomia (HFM), Goldenhar syndrome, and unilateral cleft lip and palate (UCLP). There was a significant match in the side involvement of #7 cleft and HFM (87.5%, p < 0.01). Patients with #14 cleft had plagiocephaly, UCLP, or hyperterorbitism. A patient with #30 cleft exhibited tongue tie and missing tooth. Conclusions: Due to the diverse associated craniofacial anomalies in patients with CFC, a multidisciplinary approach involving a well-experienced cooperative team is mandatory for these patients.

  • The purpose of this study was to determine whether any difference existed in craniofacial morphology between parents of children with cleft lip and/or palate and parents of children without cleft lip and/or palate as well as the characteristics of craniofacial morphology in parents of children with cleft lip and/or palate. Thirty three measurements of the various regions of cranium and face were obtained from lateral cephalometric radiograms in parents of 28 children with cleft lip and palate, 18 children with cleft lip, and 22 children with cleft palate. There were 28 couples and 40 single parents in this sample. There were 92 individuals including 41 males and 51 females. The measurements were compared with those in control subjects, including 40 adult males and 40 adult females, who had no history of craniofacial abnormalities. The total sample was compared for the sex independently. The obtained results were as follows. 1. In the cranium, both parents of cleft children had significantly shorter posterior cranial base length(S-Ba). 2. In the upper face, a significantly shorter anteroposterior length of maxilla(A'-Ptm'), particularly in the anterior region (A'-K), anterior facial depth(A-SBaL), posterior facia! height(Ptm'-SNL) and relation of subnasale to the cranial base (∠BaN'Sn) were noted in fathers of cleft children. But, all measurements were not found to be significantly different between experimental group and control group in all mothers. 3. In the lower face, both parents of cleft children showed a significantly greater Y axis angle(∠NSGn) and ramal plane angle(∠SNL-RP) in fathers of cleft children. Thus both patents showed a posteriorly rotation of mandible. The thickness of the lower lip(B-B') was significantly thicker in fathers of cleft children. 4. In the facial profile, a significantly shorter posterior facial height(S-Go) and greater angle of soft tissue facial convexity (∠BaN'Pog') were noted in the fathers of cleft children. But, all measurements were not found to be significantly different between experimental group and control group in all mothers.
