PROBLEM: During palatal fenestration procedure the vascularised, respiratory nasal lining is often sacrificed inadvertently. It normally functions to keep the inhaled air warm, humid and dust free. CONCLUSION: This vascularised nasal lining when uninvolved oncologically can easily be preserved. Preservation of the vascularised nasal lining shall decrease the leakage of nasal secretions and aid in the healing of reconstruction of the defect when local or regional flaps are used...

INTRODUCTION: Animal inflicted injuries to the face and neck are becoming much more common as people lavish affection on pets. Injuries caused by animal attacks to the face can cause complex injuries to soft and hard tissues, presented as perforations, lacerations, crushes, avulsion or fractures. An uncountable number of bacteria and virus can be found in such injuries, with a potential pathological effect to humans, regarding infections. Although the infection rate is low due to excellent blood supply to face, the injuries have disfiguring effect with possible psychological repercussion to the patients...

BACKGROUND: Reconstruction of upper extremity deformities continues to be a challenge to the reconstructive surgeon. Various loco regional, distant and free flaps are available for reconstruction. However, each has its own set of advantages and disadvantages. Of the commonly performed local flaps, radial artery forearm flap, and the posterior interosseus artery flap stand out prominently. Recently, perforator propeller flaps have been used for resurfacing the upper extremity. The anterior interosseus artery perforator flap is an uncommonly used and described flap...

Global wind patterns affect flight strategies in many birds, including pelagic seabirds, many of which use wind-powered soaring to reduce energy costs during at-sea foraging trips and migration. Such long-distance movement patterns are underpinned by local interactions between wind conditions and flight behaviour, but these fine-scale relationships are far less well understood. Here we show that remotely sensed ocean wind speed and direction are highly significant predictors of soaring behaviour in a migratory pelagic seabird, the Manx shearwater (Puffinus puffinus)...

A novel approach to fabricating and testing artificial insect wings has been developed. Utilizing these new techniques, locally harvested hawk moth (<i>Manduca sexta</i>) forewings are compared to engineered forewings with varying wing structures. A number of small, flexible engineered forewings were fabricated with identical planform size and shape but with variations in camber, ribbing, thickness and composition. A series of static and dynamic assessments compares the forewings in terms of structure and performance...

The nose is a critically important aesthetic and functional portion of the face. We can explore nasal defects following trauma or tumor resections. Reconstructive techniques based on primary closure, skin graft, local flap, regional flap and microvascular free tissue transfer provides an algorithmic framework applicable to any reconstructive problem. From 2010 to 2016, 33 patients were treated with nasal reconstruction. Malignant tumor resection was the main cause of nasal defect. The most common tumor resected was BCC (basal cell carcinoma) followed by SCC (squamous cell carcinoma)...

Eyelid reconstruction, though challenging, can produce a functional, esthetically pleasing lid. This should preferably be accomplished with a one-stage procedure, using robust, well-vascularized tissues similar to those being replaced, with minimal associated donor morbidity. According to the experience with Bichat pedicled flap in oral reconstruction, the authors propose the use of pedicle infraorbital fat pad for repair of conjunctival defect. Seven patients underwent eyelid reconstruction of full-thickness oncological or post-traumatic defects...

PURPOSE: Distal finger amputations pose a therapeutic problem with the distal fragment quality. Reimplantation remains the reference treatment for functional and aesthetic recovery of the hand. The interest of this study is to propose the reposition flap as an alternative to different hedging techniques in the proximal stump, in many situations where revascularization is impossible. It consists in osteosynthesis of the bone fragment and its coverage by a pedicled local flap. METHODS: The technique of reposition flap was evaluated retrospectively between 2003 and 2016 through a study of 13 patients compiled in Nabeul orthopedic department...

Large defects after skin malignant tumors resection were difficult to repair. We introduced a partition concept, in which the large defects were divided into several subunits, and each subunit was repaired by a certain pedicled flap to achieve a complete coverage.Between May 2012 and Oct 2016, 8 patients with skin malignant tumors underwent radical resection. Prior to surgery, the dimension of the potential defect after tumor ablation was estimated and outlined. After evaluation, the partition concept was applied and the defects were divided into several subunits...

Successful reconstruction of the cheek following excision for cutaneous malignancy requires careful consideration of defect location, size, and depth in relation to the anatomic properties of the affected cheek unit. Various reconstructive options are available to the surgeon, ranging from simple excisions to complex cervicofacial advancements to meet the needs for functional and aesthetically pleasing reconstructive outcomes. The surgeon must prevent distortion of mobile structures, such as the eyelid, nose, and lips; respect aesthetic subunits; and avoid blunting natural creases...

Reconstruction of defects of the lips after Mohs micrographic surgery should encompass functional and aesthetic concerns. The lower lip and chin compose two-thirds of the lower portion of the face. The focus of this article is local tissue transfer for primarily cutaneous defects after Mohs surgery. Various flaps exist for repair. For small defects, elliptical excision with primary closure is a viable option. During reconstruction of the lip, all of the involved layers need to be addressed, including mucosa, muscle, and the vermillion or cutaneous lip...

Mohs micrographic surgery has become the standard of care for the treatment of cutaneous malignancies. Reconstructing cutaneous defects of the nose can be challenging, as form and function must be respected to the greatest extent possible. A wide range of reconstructive techniques are used. Secondary intent, primary closure, skin grafts, local flaps, and the interpolated workhorse flaps represent the spectrum of options, each with specific advantages and disadvantages. Vigilant postoperative care, including judicious use of adjunctive procedures, can improve outcomes...

Eyelid defects disrupt the complex natural form and function of the eyelids and present a surgical challenge. Detailed knowledge of eyelid anatomy is essential in evaluating a defect and composing a reconstructive plan. Numerous reconstructive techniques have been described, including primary closure, grafting, and a variety of local flaps. This article describes an updated reconstructive ladder for eyelid defects that can be used in various permutations to solve most eyelid defects.

REVIEW
Michael J Brenner, Jeffrey S Moyer
Skin and composite grafting provide effective resurfacing and reconstruction for cutaneous defects after excision of the malignancy. The goal is to restore a natural appearance and function while preventing distortion of the eyelid, nose, or lips. With careful planning and attention to aesthetic subunits, the surgeon can camouflage incisions and avoid blunting aesthetically sensitive sulci. The surgical plan is also informed by the pathology, as basal or squamous cell carcinomas removed by Mohs micrographic excision have different prognostic and logistical considerations from melanoma...

In many cases of complex facial defects, because of advanced cutaneous malignancies, primary wound closure is impossible. In these instances, ideal results can be obtained through recruitment of adjacent tissue with the use of local flaps. Advances in local flap techniques have raised the bar in facial reconstruction; however, acceptable results to the surgeon and patient require high levels of planning and surgical technique. Defects resulting from Mohs surgery and other traumatic injuries can typically be repaired with local flaps...

James B Lucas
Facial skin defects created by Mohs micrographic surgery are commonly reconstructed using local cutaneous flaps from surrounding skin. To provide optimal survival and aesthetic outcomes, the cutaneous surgeon must command a thorough understanding of the complex vascular anatomy and physiology of the skin as well as the imperative physiologic and biomechanical considerations when elevating and transferring tissue via local skin flaps.
