Abstract
The use of free cutaneous or myocutaneous flaps in some surgeries, especially in reconstructive surgeries, is routine and imperative; nevertheless, it is controversial because of fear of flap loss due to tissue congestion and partial or complete necrosis. Different mechanisms are discussed in this process, and based on the involved mechanisms, various agents and approaches are suggested for flap salvage. Among these agents and strategies, leech therapy (hirudotherapy) can be a valuable complementary treatment; however, in this way, full attention should be given to all beneficial and harmful aspects to reach the best results. This study included a literature review of the essential complications following free tissue transfer and explained the effects of leech therapy for the respective complications. Based on the review of the literature, the essential complications following free tissue transfer were (I) venous obstruction and congestion, (II) delay in blood flow reestablishment, (III) ischemia/reperfusion injuries, and (IV) thrombus formation. Leech therapy can protect free flaps against the mentioned complications as a complementary treatment. Leech therapy is an appropriate complement, however, not a definite approach for flap salvage. Therefore, in some patients, other alternative methods or even flap removal may be a better option.

Abstract
Traumatic facial soft tissue injury often creates both aesthetic and functional deficits. In complete lip avulsions, microvascular replantation is a reconstructive option that has the potential to fulfill both of these goals. However, lip replantations remain rare and there are few reports in the literature. The authors aim to present a clinical report of a young male who sustained a human bite injury and underwent microvascular replantation of a completely avulsed lower lip and to review the literature and management of these complex injuries.

Abstract
BACKGROUND In the field of vascularized composite tissue allotransplantation, the surgical design of facial subunit grafts is an evolving concept. The purpose of the present article is to study the possibility of dividing the historical nose and lip face transplant into several morphologic and functional subunit grafts, depending on their respective supply. METHODS This study was conducted in 20 adult cadavers. The facial artery and its branches were dissected bilaterally in 16 fresh and four embalmed heads. Nasolabial perfusion was assessed by selective injection of methylene blue and eosin (n = 2) or India ink (n = 2) in the superior labial and distal facial arteries. Dynamic perfusion through the distal facial artery was illustrated by fluoroscopy (n = 3). Three nose-upper lip grafts were harvested and injected with barium sulfate for microangiography computed tomographic analysis. Finally, three isolated nasal and bilabial grafts were procured and their vascular patency assessed by fluoroscopy. RESULTS The distal facial artery can perfuse the entire nose, septum, and upper lip, without any contribution of the superior labial artery. A dense anastomotic network indeed exists between the respective distal rami of both vessels. Furthermore, the exclusion of the superior labial artery from the harvested nasal subunit allowed safe bilabial subunit procurement, from the same specimen. CONCLUSIONS The authors' results demonstrate the feasibility of harvesting nasal and labial subunits, in an isolated or a combined manner. These results can find applications in subunit autologous replantation, allotransplantation, allogenic face partial retransplantation, and the emerging field of vascularized composite tissue engineering.

Abstract
Dog bite injuries are common sources of morbidity with an estimated incidence of 4.5 million bites per year with over 350,000 requiring treatment in the emergency room. Children under the age of 14 are most likely to be affected with a peak age of 5-9 years old. We report a case of a 24-month-old female who sustained a large composite facial avulsion injury from a pit bull dog bite. The avulsed tissue involved a substantial portion of the patient's mid-face, including the entire soft tissue of the nose, upper lip, part of the left cheek, and left oral commissure. Artery-only microvascular replantation was performed because no recipient vein could be identified from the facial defect. Medicinal leech therapy was used for eight days postoperatively to prevent venous congestion. The patient experienced significant blood loss due to leech therapy and required nearly 29 L of blood product replacement. At the last follow up of 8 months postoperatively, the patient was recovering well with significant improvement in function and cosmesis of the mid-face. This case describes a successful artery-only replantation of an avulsive bite injury to the face of a young child. Despite the technical difficulty of cases such as this one, microvascular replantation should be attempted because when successful it provides a superior cosmetic and functional result to other reconstructive techniques.

Abstract
IMPORTANCE Upper lip avulsion after traumatic dog bite is a serious cause of facial disfigurement for which there is no consensus on management in the acute setting. OBJECTIVE This review was prompted by a case at our institution and is intended to display the available evidence in the management of the patient after dog bite injury to the upper lip. Our main goals are to create a management algorithm using current evidence and to stimulate further clinical investigation to improve outcomes in patients with facial dog bite injuries. EVIDENCE REVIEW A review of English literature was performed using Pubmed/MEDLINE for case reports and case series of lip replantation using microvascular anastomosis. Additional review of hyperbaric oxygen therapy, medicinal leech therapy, lip reconstruction methods, and reapproximation was performed. Reference searches were performed for all retrieved articles. FINDINGS Microvascular replantation is a successful method of acute management in dog bite injuries of the lip. Hyperbaric oxygen therapy and medicinal leech therapy improve outcomes. Immediate cross-lip flaps and immediate reapproximation are alternative techniques that can be performed in the acute setting, but further investigation is required. CONCLUSIONS The repair of the upper lip after a dog bite is a priority due to the functional and psychiatric sequelae associated with facial disfigurement. Microvascular replantation should be considered first-line. Immediate reapproximation without microvascular reanastomosis and immediate reconstruction may also be performed. A stepwise clinical algorithm may aid the surgeon in the acute management of dog bite trauma to the lip.

Abstract
BACKGROUND Although there are numerous case reports and small case series describing the experiences of leech therapy in various circumstances, there are relatively few large studies evaluating the effectiveness of leeching to relieve venous congestion. The therapeutic value of leeching is illustrated by these reports but the current literature lacks a cohesive summary of previous experiences. METHODS An electronic search of PubMed, the Cochrane library and the Centre for Reviews and Dissemination between 1966 and 2009 was used to retrieve human studies published in the English language evaluating outcomes following leech therapy. The "success" and "failure" of leech therapy were the primary outcome measures and secondary outcomes included complications, number of leeches used, pharmacological adjuncts and blood transfusion requirements. RESULTS In total, out of 461 articles, 394 articles met the exclusion criteria. The 67 included papers reported on 277 cases of leech use with an age range of 2-81 years and a male to female ratio of almost 2:1. The overall reported "success" rate following leech therapy was 77.98% (216/277). In terms of secondary outcome measures, 49.75% of cases (N = 101) required blood transfusions, 79.05% received antibiotics (N = 166) and 54.29% received concomitant anticoagulant therapy. The overall complication rate was 21.8%. CONCLUSION In the absence of robust randomized controlled trials on which the evidence may be based, this synthesis of current best evidence guides clinicians during the process of consenting patients and using leeches in their practice.

Abstract
Previous investigators have not described some of the new anatomic variations or provided quantitative and analytical data of the arterial anatomy of the lips in as much depth as in this study. Dissections of 14 different facial sides of cadavers were done. Through investigating the arterial supply of the upper and lower lips, measurements were performed and statistically analyzed. The main arterial supply of the upper lip was from the superior labial artery (SLA, mean external diameter, 1.8 mm [SD, 0.74 mm]); in addition, the subalar and septal branches contributed to its vascularization. The origin of the SLA was above the labial commissure in 78.6%. The subalar branch was not found but replaced by the alar artery that arose from the infraorbital artery in 1 specimen. The main arterial supply of the lower lip was derived from 3 branches of the facial artery, the inferior labial artery (mean external diameters, 1.4 mm [SD, 0.31 mm]) and the horizontal and vertical labiomental arteries. The inferior labial artery originated mostly below the labial commissure in 42.9% and formed a common trunk with the SLA in 28.6%. The horizontal labiomental artery was present in all, but vertical labiomental artery was absent in 21.4% of specimens. Overall, observed anatomic variations were classified into types I to VIII. Significant relations between the demographic variables and measured parameters were reported including the correlation coefficient among evaluated parameters. In conclusion, this study provides various information that aids in creating new flaps and supports the vascular base for clinical procedures in reconstructive surgery of the lip.

Abstract
The reconstruction of lip defects through the use of the Abbe flap and other lip flap procedures involves surgical manipulation of one of the major branches of the facial artery, specifically the superior labial artery (SLA). We examined 284 hemifaces derived from 142 formalin fixed cadavers. Observations regarding the distribution patterns of the facial artery were recognized and categorized into five Types, labeled "A" through "E". Type A (135, 47.5%): facial artery bifurcates into SLA and lateral nasal (the latter gives off inferior and superior alar and ends as angular); Type B (110, 38.7%): similar to Type A, except lateral nasal terminates as superior alar (angular artery is absent); Type C (24, 8.4%): facial artery terminates as SLA; Type D (11, 3.8%): angular artery arises directly from facial arterial trunk rather than as the termination of lateral nasal, with the facial artery ending as superior alar; Type E (4, 1.4%): facial artery terminates as a rudimentary twig without providing any significant branches. Furthermore, we were able to categorize variations within each Type. Sub-Type variations were examined in Types A through C (A: 1-7; B: 1-4; C: 1-3). Our aim was to equip both the anatomist and surgeon with a more thorough understanding of the vasculature of the face, as well as to enable plastic surgeons to have a more confident approach to reconstructive procedures in this region.
