Article
Background Lower blepharoplasty is a common cosmetic operation that relies on minimal postoperative scarring, but Asian patients are at higher risk than Caucasians for hypertrophic and/or widened scars. Botulinum toxin type A (BTX) injections are widely employed to alleviate dynamic facial rhytids and also can improve scar quality by reducing scar...
Article
Background: The main objective of contemporary orthognathic surgery is to correct dentofacial deformities. Nonetheless, many adjunct procedures to enhance the esthetic outcome in orthognathic surgical cases have been successfully incorporated to improve patient satisfaction. The authors report our preliminary experience of performing simultaneous...
Article
In rare instances, cleft lip and palate occur in association with synechia, intraoral fibrous bands connecting the maxilla and mandible. The main concern in synechia is a restricted mouth opening that leads to airway and feeding problems. This study reports our experience in the treatment of 3 cases and includes a review of the literature. Three pa...

Background/purpose: The Bonebridge (BB) is a newly designed transcutaneous bone conduction hearing implant. We describe, for the first time, simultaneous BB implantation and different surgical techniques of auricular reconstruction for microtia patients with aural atresia/stenosis. Methods: Ten patients with unilateral or bilateral microtia unde...
Article
Introduction: Botulinum neurotoxin A (BoNT-A) is a minimally invasive and technically straightforward treatment of masseter muscle (MM) volume reduction and facial contouring, but the literature on its long-term effect on MM volume remains unclear. Objective: This study aimed to assess quantitatively for progressive volume changes of lower facia...

Upper lip scars are at risk of hypertrophy. Our center therefore uses microporous tape and silicone sheeting for postoperative scar care following cleft lip repair. However, some babies have previously ingested their silicone sheeting, which has the potential for respiratory compromise or gastrointestinal obstruction. Self-dry silicone gel is repor...
Article
Background: Advances in three-dimensional imaging and three-dimensional printing technology have expanded the frontier of presurgical design for microtia reconstruction from two-dimensional curved lines to three-dimensional perspectives. This study presents an algorithm for combining three-dimensional surface imaging, computer-assisted design, and...
Article
Background: Timing of surgical intervention in hemifacial microsomia (HFM) is controversial. Although mandibular osteodistraction in childhood for HFM is popular, recent data for single-stage distraction in growing HFM patients demonstrated long-term relapse. Literature suggests that adolescents in the late mixed dentition age or permanent dentiti...
Article
The advent of three-dimensional stereo-photogrammetry in recent years has vastly helped the craniomaxillofacial field improve in terms of preoperative and intraoperative decision making. With regard to the auricle though, there is paucity of research as to the application of this promising technology. A total of 20 normal adult ears were included i...
Article
Donor-site deformity may complicate autologous costal cartilage harvest for microtia reconstruction. This is reportedly prevented by total subperichondrial costal cartilage harvest, costochondral growth center preservation, donor-site reconstitution with morselized leftover costal cartilage, and perichondrial repair (Kawanabe-Nagata method). Howeve...
Article
This study quantified the lung volume development of pectus excavatum (PE) patients using chest computed tomography (CT) 3-dimensional volumetric reconstructions. The technique permits current and retrospective analyses of data from different institutions. We analyzed the records of PE patients who underwent chest CT preoperatively between 2005 and...
Article
Staged auricular reconstruction remains mainstream among the various techniques of microtia reconstruction using autogenous costal cartilage. The initial stage involves fabrication and implantation of the cartilage framework, followed by projection of the reconstructed auricle in the second stage. During the projection stage, the line of incision i...
Article

In microtia reconstruction, maintaining a healthy contact between the skin and the fabricated cartilage framework is essential to attaining a smooth and accentuated contour of the reconstructed auricle. Conventional means to achieve this include bolster sutures and continuous suction drains, both of which have associated shortcomings. A new dressin...

A 22-year-old man presented with a scarred neophallus and complex hypospadias. The local penile skin was inadequate for urethral repair. A 16 cm free radial forearm flap was used for urethral replacement. Microvascular anastomosis allowed this flap to remain viable and functional. One year postoperatively, the patient had satisfactory functional an...
Article
For auricular reconstruction of external auricle, the goals of the surgery are (1) in the fabrication of the morphologically complete 3-dimensional costal cartilage framework (3-dimensional frame) of the auricle, and (2) in the attainment of ample skin surface area to cover the grafted 3-dimensional frame, so that more than satisfactory results can...

Article
The endoscope has been used to visualise the upper face and brow in aesthetic facial surgery which is performed without a coronal incision. We applied these principles to repair zygomatic fractures with the aid of a 4 mm, 30 degree telescope inserted through a small temporal incision. Fracture sites at the zygomatic arch and the zygomaticofrontal s...
Article
Spinal fusion with either non-vascularized or vascularized bone grafts has been well documented for inflammatory, degenerative, post-oncological and post-traumatic reconstruction Vascularized bone graft has been proven to have more rapid healing and better clinical results. A few reports have indicated that free vascularized fibular bone grafts hav...
