Chang Gung Forum: An Exemplary Strategy for Implementing a Multidisciplinary Network of Experts in Craniofacial Anomalies.

Introduction: The Chang Gung Forum has been dedicated to the care of craniofacial anomalies since 2000. This annual continuing medical education program focuses on orofacial cleft and surgery-first orthognathic surgery by providing up-to-date information and management guidelines. This study explored how the Chang Gung Forum has influenced medical perspectives, decisions, and practices in a multidisciplinary craniofacial team.

Platelet-Rich Plasma Lysate Enhances the Osteogenic Differentiation of Adipose-Derived Stem Cells.

Adipose-derived stem cells (ADSCs) have become an accepted source of cells in bone tissue engineering. This study aimed to investigate whether platelet-rich plasma (PRP) lysate can replace traditional fetal bovine serum as a culture medium with the enhanced proliferation and osteogenic potential of ADSCs. We divided the experiment into 5 groups where the ADSCs were cultured in an osteogenic medium containing 2.

Development of the Customized Asymmetric Fixation Plate to Resist Postoperative Relapse of Hemifacial Microsomia Following BSSO: Topology Optimization and Biomechanical Testing.

Hemifacial microsomia (HFM), one of the most common congenital facial anomalies, was usually treated with the bilateral sagittal split osteotomy (BSSO) procedure to correct the asymmetric appearance and malocclusion of the mandible. However, the frequent post-operative relapse incidents would lead to the restoration of the mandibular segment to its preoperative position and failure of the BSSO procedure. In this study, a customized asymmetric fixed plate (CAF plate) was developed to resist relapse due to hemifacial microsomia occlusal forces and the different muscular traction forces on both sides of the mandible.

Impact of the Different Types of Le Fort I Maxillary Surgical Movement on Nasal Width Changes: A Photogrammetric Analysis.

Background: Le Fort I maxillary movements affect nasal width, but nasal width changes with specific movement types have not been formally addressed to date.

Objectives: The purpose of this study was to analyze and compare the changes in nasal width with different maxillary movements.

Methods: A retrospective study was performed among consecutive patients who underwent bimaxillary orthognathic surgery (n = 138) and who were grouped based on the type of maxillary movement (ie, maxillary advancement with intrusion [MAI], maxillary advancement with extrusion [MAE], and maxillary setback with intrusion [MSI]).

Objective and subjective long term outcome of maxillomandibular advancement in obstructive sleep apnea.

Study Objectives: To evaluate the objective and subjective long-term outcome of maxillomandibular advancement (MMA) in Far-East Asian patients with moderate to severe obstructive sleep apnea (OSA).

Methods: This is a long-term follow-up study to evaluate the treatment outcome of MMA in OSA patients by objective polysomnography (PSG) and subjective questionnaires (Pittsburgh Sleep Quality Index-PSQI, Insomnia Severity Index-ISI, Beck Anxiety Inventory-BAI, Beck Depression Inventory-BDI, Epworth Sleepiness scale-ESS, and Short Form-36 Quality of Life-SF-36). Evaluation was done before surgery and we followed these patients one and two years after surgery.

Maxillomandibular Rotational Advancement: Airway, Aesthetics, and Angle's Considerations.

Obstructive sleep apnea is a medical syndrome with multifactorial pathophysiology. Surgery can be the primary treatment option when anatomic factors are identified with narrowing at specific or general levels of pharyngeal airway. The surgeries are directed to the etiologic anatomic structure to achieve greatest effectiveness.

A novel anatomical thin titanium mesh plate with patient-matched bending technique for orbital floor reconstruction.

This study developed an anatomical thin titanium mesh (ATTM) plate for Asian orbital floor fracture based on the medical image database. The computer aided stamping analysis was performed on four hole/slot patterns included the control type without hole design, circular hole pattern, slot pattern and hole/slot hybrid patterns within the ATTM plate with upper/lower dies of averaged orbital cavity reconstruction models. The curved-fan ATTM plate with 0.

Anatomical Thin Titanium Mesh Plate Structural Optimization for Zygomatic-Maxillary Complex Fracture under Fatigue Testing.

This study performs a structural optimization of anatomical thin titanium mesh (ATTM) plate and optimal designed ATTM plate fabricated using additive manufacturing (AM) to verify its stabilization under fatigue testing. Finite element (FE) analysis was used to simulate the structural bending resistance of a regular ATTM plate. The Taguchi method was employed to identify the significance of each design factor in controlling the deflection and determine an optimal combination of designed factors.

Development of a novel anatomical thin titanium mesh plate with reduction guidance and fixation function for Asian zygomatic-orbitomaxillary complex fracture.

For this study we developed an anatomical thin titanium mesh (ATTM) plate for Asian zygomaticomaxillary complex (ZMC) fracture repair with reduction guidance and fixation function. The ATTM plate profile was designed as an L-shape to fix at the anterior maxilla and lateral buttress of the ZMC. Computer-aided stamping analysis was performed on four screw-hole patterns in the ATTM plate - a control without screw-holes, square screw-holes, double screw-holes, and large-diameter, double screw-holes - using upper/lower dies of averaged ZMC reconstruction models.

Experience with the transparotid approach via a mini-preauricular incision for surgical management of condylar neck fractures.

Introduction: The aim of this study was to describe our experiences of a mini-preauricular transparotid approach for direct reduction and plating of condylar neck fractures.

Materials And Methods: A retrospective study was conducted on 58 patients from 2009 to 2011 with 69 condylar neck fractures in Chang Gung Memorial Hospital. The fractures were treated surgically either with a 2-cm mini-preauricular and transparotid approach in 29 patients with 36 fractures, or via endoscope-assisted intraoral, or facelift or retromandibular approaches in a control group of 29 patients with 32 fractures.

Increasing the success of reverse sural flap from proximal part of posterior calf for traumatic foot and ankle reconstruction: patient selection and surgical refinement.

In this report, we present our experience on the use of the reverse sural flap for traumatic foot and ankle reconstruction. The patient selection and surgical refinement are discussed. From 2007 to 2010, 11 consecutive patients underwent modified reverse sural flap at the Chang Gung Memorial Hospital.
