Parry-Romberg syndrome is a rare neurocutaneous syndrome characterized by progressive shrinkage and degeneration of the tissues usually on only one side of the face. It is usually difficult to restore the facial contour due to skin tightness. In this case report, we report a forehead reconstruction with custom-made three-dimensional (3D) titanium implant of a Parry-Romberg syndrome patient who was treated with multiple fat grafts but had limited effect. A 36-year-old man presented with hemifacial atrophy. The disease progressed from 5 to 16 years old...

The decision of which surgical approach to use for the treatment of a multifocal craniofacial abscess is still a controversial matter. A failure to control disease progress in the craniofacial region can potentially put the patient's life at risk. Therefore, understanding the various ways to approach the craniofacial region helps surgeons to obtain satisfactory results in such cases. In this report, we describe a patient who visited the emergency department with a large swelling in his right cheek. A blood test and computed tomography revealed odontogenic maxillary sinusitis...

The crystal structures of isomeric rac -2-(4-nitro-phen-yl)-3-phenyl-2,3,5,6-tetra-hydro-4 H -1,3-thia-zin-4-one (C16 H14 N2 O3 S) ( 1 ) and (2 S )-2-(3-nitro-phen-yl)-3-phenyl-2,3,5,6-tetra-hydro-4 H -1,3-thia-zin-4-one (C16 H14 N2 O3 S) ( 2 ) are reported here. While 1 crystallizes in a centrosymmetric space group, the crystal of 2 chosen for data collection has mol-ecules only with (2 S ) chirality. This is the result of spontaneous resolution during crystallization, as the synthesis produces a racemic mixture...

The syntheses and crystal structures of 2,3-bis-[3-(tri-fluoro-meth-yl)phen-yl]-2,3-di-hydro-4 H -1,3-benzo-thia-zin-4-one (di- m -CF3 ; C22 H13 F6 NOS) ( 1 ) and 2,3-bis-(4-methyl-phen-yl)-2,3-di-hydro-4 H -1,3-benzo-thia-zin-4-one (di- p -CH3 ; C22 H19 NOS) ( 2 ) are reported. Each structure is racemic: the asymmetric unit of 2 consists of two mol-ecules. In both 1 and 2 , the six-membered 1,3-thia-zine ring is close to an envelope conformation with the chiral C atom forming the flap. In 1 , the 2-aryl group is pseudo-equatorial, while in 2 it is pseudo-axial...

Face transplant has rapidly advanced since the first operation in 2005, and to date, 40 partial or full-face transplants have been performed. The safety and efficacy of this operation are aided at all phases by supporting technologies. These include advanced imaging techniques to plan the operation, devices to monitor the flap in the immediate perioperative period, and noninvasive imaging and serum markers to monitor for acute and chronic rejection. Some of the technologies, such as those used in the immediate perioperative period, have extensive evidence supporting their use, whereas those to detect acute or chronic rejection remain investigational...

BACKGROUND: The perforator flap concept has revolutionized reconstructive surgery. Recently, the attention has moved toward flaps based on capillary perforators, which have been usually neglected in the past as reliable perforators. The aim of this article is to report a series of freestyle capillary perforator-based island flap (c-PBIF) for reconstruction of skin cancer defects of the face, body, and extremities. PATIENTS AND METHODS: Between September 2015 and July 2017, 20 consecutive patients underwent c-PBIF reconstruction of facial, body, and limb defects after melanoma and nonmelanoma skin cancer excision...

With the advancement in biomaterial sciences, tissue engineered scaffolds are developing as a promising strategy for the regeneration of damaged tissues. However, only a few of these scaffolds have been translated into clinical applications. One of the primary drawbacks of the existing scaffolds is the lack of adequate oxygen supply within the scaffolds. Oxygen producing biomaterials have been developed as an alternate strategy but are faced with two major concerns. One is controlling the rate of oxygen generation, and the other is the production of reactive oxygen species...

REVIEW
Chung-Chen Hsu, James Tseng, Yu-Te Lin
When faced with reconstructing metacarpal defects, various options have been described. We describe a chimeric medial femoral condyle osteocutaneous flap as a new method for providing multiple bone grafts as well as soft tissue coverage in a single stage. The medial femoral condyle has become an area of increased interest given the versatility it allows in harvesting the bone. This osteocutaneous flap is useful when reconstructing small- to medium-sized adjacent metacarpal bone defects. The chimeric design of the flap lends flexibility at the time of inset that is absent for other options of vascularized bone grafts...

The demand for facial feminization is increasing in transsexual patients. Masculine foreheads present extensive supraorbital bossing with a more acute glabellar angle, whereas female foreheads show softer features. The aim of this article is to describe our surgical technique for fronto-orbital feminization. The mask-lift technique is an upper face-lift. It provides rejuvenation by correcting collapsed features, and fronto-orbital feminization through burring of orbital rims and lateral canthopexies. Depending on the size of the frontal sinus and the thickness of its anterior wall, frontal remodeling is achieved using simple burring or by means of the eggshell technique...

PURPOSE: Severe physical facial deformities due to surgical interventions can have significant psychosocial consequences to patient's relationships with friends and family and thus, has a considerable impact on their quality of life. We have developed a 3D prosthesis for a 56-year-old woman diagnosed with epidermoid carcinoma at the right hemiface, to improve her quality of life. METHODS: The patient started radiotherapy with modulated intensity. To deal with the advance of the process, a maxilectomy of supra structure with modified radical cervical emptying on the right hemiface was performed...

INTRODUCTION: The face is unique because functional and aesthetic considerations are equally important. Extensive deep chemical burns of the face are usually reconstructed with flaps. In males, the use of the hair - bearing superficial temporal artery flap has the advantage of achieving a satisfactory outcome with regards to both function and aesthetics.

BACKGROUND: Festoons and malar bags present a particular challenge to the plastic surgeon and commonly persist after the traditional lower blepharoplasty. They are more common than we think and a trained eye will be able to recognize them. Lower blepharoplasty in these patients requires addressing the lid-cheek junction and midcheek using additional techniques such as orbicularis retaining ligament (ORL) and zygomaticocutaneous ligament (ZCL) release, midface lift, microsuction, or even direct excision (Kpodzo e al...

Flapping flight is relatively costly for soaring birds such as raptors. To avoid costly flight, migrating raptors generally avoid flying over water. As a result, all but one of the global raptor migration flyways are largely over land. The East Asian oceanic flyway for raptors is the exception. Raptor species using this flyway migrate by island-hopping, flying over open ocean for distances of up to 300 km between islands. We used satellite telemetry data for grey-faced buzzards Butastur indicus , a species that dominates the southern part of the flyway, to investigate the geographical and atmospheric factors responsible for the suitability of this flyway for raptor migration...

Recent facial paralyses, in which fibrillations of the mimetic muscles are still detectable by electromyography (EMG), allow facial reanimation based on giving new neural stimuli to musculature. However, if more time has elapsed, mimetic muscles can undergo irreversible atrophy, and providing a new neural stimulus is simply not effective. In these cases function is provided by transferring free flaps into the face or transposing masticatory muscles to reinstitute major movements, such as eyelid closure and smiling...

Importance: In the setting of facial paralysis, inadequate eyelid closure and lower eyelid ectropion can lead to corneal exposure and impaired quality of life. Repair of paralytic ectropion is challenging, and an ideal surgical approach for all cases has not been identified. Objective: To assess the patient-reported outcomes and eyelid position improvement in patients with flaccid facial paralysis undergoing lateral eyelid coupling with a tarsal strip canthoplasty and modified tarsoconjunctival flap to correct eyelid malposition...
