Further delineation of CDC45-related Meier-Gorlin syndrome with craniosynostosis and review of literature.

Meier-Gorlin syndrome (MGS) is a rare autosomal recessive disorder characterized by the triad of short stature, microtia and absent or small patellae. We report on a patient with MGS secondary to biallelic mutations in CDC45 detected on whole exome sequencing (WES). Patients with MGS caused by mutations in CDC45 display a distinct phenotype characterized by craniosynostosis and anorectal malformation.

Influence of Bimaxillary Surgery on Pharyngeal Airway in Class III Deformities and Effect on Sleep Apnea: A STOP-BANG Questionnaire and Cone-Beam Computed Tomography Study.

Purpose: To evaluate pharyngeal airway space (PAS; nasopharyngeal, oropharyngeal, and total airway) volume and the correlation of an obstructive sleep apnea (OSA) and hypopnea syndrome screening questionnaire (STOP-BANG) with various mandibular setbacks during bimaxillary surgery and compare these findings with an age- and gender-matched skeletal Class I control group.

Patients And Methods: This retrospective cohort study was composed of patients with skeletal Class III discrepancy who underwent bimaxillary jaw surgery and were assessed with STOP-BANG score, cephalometry, and cone-beam computed tomography (of the PAS). The predictor variable was bimaxillary jaw surgery and included 4-, 6-, and 8-mm setbacks.

Orthodontic-orthognathic interventions in orthognathic surgical cases: "Paper surgery" and "model surgery" concepts in surgical orthodontics.

Thorough planning and execution is the key for successful treatment of dentofacial deformity involving surgical orthodontics. Presurgical planning (paper surgery and model surgery) are the most essential prerequisites of orthognathic surgery, and orthodontist is the one who carries out this procedure by evaluating diagnostic aids such as crucial clinical findings and radiographic assessments. However, literature pertaining to step-by-step orthognathic surgical guidelines is limited.

Comparative Evaluation of the Pharyngeal Airway Space in Unilateral and Bilateral Cleft Lip and Palate Individuals With Noncleft Individuals: A Cone Beam Computed Tomography Study.

Objective: To evaluate the pharyngeal airway space changes in complete unilateral cleft lip and palate (UCLP) and bilateral cleft lip and palate (BCLP) individuals, and compare with age and sex-matched noncleft (NC) control subjects.

Design: Retrospective study.

Setting: Cleft and Craniofacial Centre, KK Women's and Children's Hospital, Singapore.

Repair of inferior sternal cleft using bilateral sternal bar turnover flaps in a patient with pentalogy of cantrell.

We report a case of sternal reconstruction using bilateral sternal bar turnover flaps in a 4-year-old boy with an inferior sternal cleft, as part of Cantrell's pentad. When the patient was 10 months old, he underwent sternal reconstruction using a resorbable poly-L-lactic-polyglycolic acid plate in the first stage when there was insufficient autogenous tissue to provide a reliable reconstruction. Bilateral sternal bar turnover was performed in the second stage at 4 years of age.

High Le Fort I and bilateral split sagittal osteotomy in Crouzon syndrome.

Crouzon syndrome is a rare, autosomal dominant disease from a fibroblast growth factor receptor 2 gene mutation, characterized by premature craniosynostosis, hypertelorism, orbital proptosis, psittichorina, hypoplastic maxilla, and mandibular prognathism. We present an adult 32-year-old Crouzon syndrome patient who underwent an elective High Le Fort I and bilateral split sagittal osteotomy for midface advancement with a background of jaw malocclusion and obstructive respiratory symptoms. The operation features a potential dynamic movement of the secured airway in the surgical field and close proximity to exposed ocular structures.

Repair of ectopia cordis using a resorbable poly-L-lactic-polyglycolic acid plate in a patient with pentalogy of Cantrell.

We present a case of a 10-month-old male infant with thoracoabdominal ectopia cordis, as part of Cantrell pentad, repaired using a poly-L-lactic-polyglycolic acid plate, a resorbable plating system widely used in craniomaxillofacial reconstruction. This is the first reported case of sternal reconstruction using a poly-L-lactic-polyglycolic acid plate. The repair was successfully carried out without cardiopulmonary compromise and good aesthetic outcome was achieved.

Use of tissue sealants in face-lifts: a metaanalysis.

Background: This review sought to determine the efficacy of tissue sealants such as fibrin tissue adhesives and platelet-rich plasma in reducing postoperative drainage, ecchymosis, and edema after face-lift surgery.

Methods: The electronic databases MEDLINE (1966-May 2007) and EMBASE (1974-May 2007) and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched for human studies, randomized controlled trials, controlled clinical trials, metaanalyses, and reviews of randomized controlled trials using the key words "fibrin tissue adhesive," "tissue sealant," "platelet-rich plasma," "face-lift," "rhytidoplasty," "rhytidectomy," and "facial plastic surgery." The search yielded 10 articles, only 3 of which met our inclusion criteria.

Platelet-rich plasma has no effect on increasing free fat graft survival in the nude mouse.

Background: Free fat grafts have an unpredictable survival rate, which may be dependent on host bed vascularity. Therefore, the authors hypothesized that the presence of growth factors in platelet-rich plasma (PRP), may enhance free fat graft survival.

Methods: Free fat grafts and autologous PRP were harvested from a healthy female and processed using the Coleman technique and the Medtronic Magellan system respectively.

An audit on orthognathic surgery: a single surgeon's experience.

The aim of this article was to present a retrospective audit on a single surgeon's experience with orthognathic surgery. This was a retrospective review of orthognathic cases performed from January 1, 2000, to January 1, 2006. There were 37 male and 65 female patients with a mean age of 20 years.
