Patients with HFM require individualized diagnosis and treatment planning because of diverse phenotypes and associations with other anomalies.

BACKGROUND: Intermediate rhinoplasties are performed during preschool to reduce the patients' psychosocial burden. At our institution, limited dissection of the cartilages followed by suspension and interdomal sutures was performed through an alar rim incision on the cleft side to minimize the risk of iatrogenic nasal growth restriction. However, the long-term outcomes of "limited intermediate rhinoplasty" through skeletal growth are uncertain. MATERIALS AND METHODS: A retrospective review of al

The results might provide primary data for individualized diagnosis and treatment planning for pre-adolescent PRS patients despite a single institution-based data.

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.

These findings might be used as basic guidelines for successful treatment planning and prognosis prediction in UHFM patients.

Rotation-advancement repair (RAR) has been the most widely used technique for unilateral cleft lip repair. We recently used a straight-line repair with medial orbicularis muscle lengthening (SLR-ml) technique, based on the hypothesis that it could minimize the postoperative scar appearance without causing s short-lip deformity when muscle reorientation is performed correctly. A retrospective cohort study was conducted on unilateral complete cleft lip patients who underwent cheiloplasty between 2

ABSTRACT: The purpose of this study was to investigate the effects of early spheno-occipital synchondrosis (SOS) fusion in preadolescent patients with syndromic craniosynostosis (SC) on the craniofacial skeletal patterns. Twenty preadolescent SC patients were divided into the fused SOS (FS, n = 10; 8 Crouzon and 2 Apert) and not-fused SOS groups (NFS, n = 10; 9 Crouzon and 1 Apert). Lateral cephalograms (mean age: 9.60 years, cervical vertebral maturation index: stage I and II) were used to inve

Background Autologous fat grafts are widely used in plastic surgery, but they have the disadvantage of unpredictability due to variable resorption. This meta-analysis examined the literature on the survival rate of autologous fat grafts using objective markers, and investigated the factors that affected the survival rate. Methods The reviewers searched the PubMed, EMBASE, and Cochrane Library databases from January 2001 to December 2017. A meta-analysis was performed to estimate fat graft surviv

The aim of this study was to quantitatively compare the effect of DO on the cranial vault according to the age of the patient and direction of distraction. METHODS This was a retrospective study of patients with craniosynostosis who underwent DO in the anteroposterior direction. Postdistraction changes in intracrania

ABSTRACT: The purpose of this study was to investigate the type and frequency of use of treatment modalities (Tx-Mods) in patients with syndromic craniosynostosis (SC) using longitudinal follow-up data. A total of 28 patients with SC (24 Crouzon, 2 Apert, and 2 Antley-Bixler syndromes), who were treated at the Department of Orthodontics, Seoul National University Dental Hospital, Seoul, South Korea between 1998 and 2020, was included. According to the degree of midface hypoplasia (MH) at the ini

Temporal hollowing is a contour deformity that results in a concavity or hollowing of the temporal region, causing significant cosmetic problems that affect patients both physically and psychologically. For these patients, cranioplasty is needed for protective coverage of the brain and to restore a pleasing aesthetic contour to the cranium. We report a case in which titanium mesh was used as a customized craniofacial implant for a bony defect and a silicone implant was used for soft tissue augme

The purpose of this study was to classify and characterize facial asymmetry (FA) phenotypes in adult patients with unilateral cleft lip and palate (UCLP) and skeletal class III malocclusion. The samples comprised 52 adult UCLP patients (36 men and 16 women; mean age, 22.43 y) who had undergone orthognathic surgery for correction of class III malocclusion. After measurement of 22 cephalometric parameters in posteroanterior cephalograms taken 1 month before orthognathic surgery, principal componen

The zygomaticomaxillary complex (ZMC) functions as a buttress for the face and is the cornerstone to a person's aesthetic appearance, by both setting the midfacial width and providing prominence to the cheek. Malar deficiency is often acquired by blunt injury incurred in a traumatic accident, resulting in ZMC fracture. A 48-year-old male patient presented a right ZMC fracture after contusion injury by a baseball. He only received conservative management and later he suffered discomfort during mo

The purpose of this study was to investigate the distribution and phenotype of Goldenhar syndrome (GS) and its association with other anomalies. The samples consisted of 18 GS patients (6 males and 12 females; mean age at investigation, 7.4 ± 4.8 y) who were treated or followed up at the Department of Orthodontics, Seoul National University Dental Hospital between 1999 and 2021. The prevalence of side involvement and degree of mandibular deformity (MD), midface anomalies, and association with ot
