Application of botulinum toxin type A in myocutaneous flap expansion.

Background: Although the use of the expanded myocutaneous flap has many advantages, the time course is prolonged. The net gain in surface area during acute expansion is insufficient. In this study, botulinum toxin type A was applied to shorten the flap expansion period while obtaining an adequate surface area that would meet surgical requirements.

Reduction malarplasty with a new L-shaped osteotomy through an intraoral approach: retrospective study of 418 cases.

Background: Oriental people usually have a wide midface and a prominent zygoma. Reduction malarplasty is one of the most frequently requested procedures for improvement of the facial contour in the Orient. Some methods involve coronal or preauricular incision for osteotomy, but this increases the likelihood of skin scars and injury to facial nerves, and increases the duration of surgery.

Rhinoplasty in Chinese: management of lower dorsum and bulbous nasal tip.

Background: Bulbous nasal tips and lower dorsa are common facial features in Chinese people, and surgery to reshape these is frequently requested. The use of silicone implants in rhinoplasty has been widely used in China for many years, but is not suitable for patients seeking Caucasian tip shapes. The creation of an excessively high tip supported only by a silicone implant inevitably leads to implant extrusion.

Technical innovations in ear reconstruction using a skin expander with autogenous cartilage grafts.

Pioneers such as Tanzer and Brent have established the foundations of microtia reconstruction using an autogenous costal cartilage framework. The framework and its skin coverage are the two limiting factors in ear reconstruction. At the present time autogenous rib cartilage and mastoid skin are still first choice materials for most surgeons.

Using a remnant ear to reconstruct the tragus in total ear reconstruction.

Although the tragus is a small part of the auricle, it is necessary for a reconstructed ear because the excavated conchal region looks quite like a meatus when a prominent tragus casts a shadow on it. To our knowledge, there have been very few reports that specifically address tragus reconstruction. This article discusses various techniques and provides detailed knowledge regarding tragus reconstruction.

The anatomy and application of the postauricular fascia flap in auricular reconstruction for congenital microtia.

Background: The various layers of the scalp are widely used in reconstructive procedures. The technique used for soft tissue coverage seems to influence the framework extrusion rate in auricular reconstruction. We have investigated the role of the postauricular fascial flap in providing ample, thin neurovascular cover to facilitate ear reconstruction in congenital microtia.

[vrk1 gene mutation test in two Chinese pedigrees of the first and second branchial arch syndrome].

Objective: To explore the role of vrk1 gene in two Chinese pedigrees of the first and second branchial arch syndrome.

Method: Sixty members in 2 Chinese pedigrees were recruited. The exon 2 -13 were analyzed by polymerase chain reaction and direct sequencing.
