Development of a Risk Prediction Model for Complications Following Forehead Flaps for Nasal and Periorbital Reconstruction.

BACKGROUND: Forehead flaps are a workhorse for nasal reconstruction, but complications occur in up to 30% of patients and risk factors are not well characterized. This study aimed to identify risk factors for complications, and provide clinicians a method to stratify patient risk to facilitate shared decision-making. MATERIALS AND METHODS: This retrospective study included patients who underwent forehead flaps between 2007 and 2020. Demographic and treatment characteristics were abstracted, in addition to clinical outcomes data. Multivariable regression was conducted, with step-wise variable elimination to determine inclusion in the final model. From the final regression, a risk-stratification scheme was developed. RESULTS: One hundred ninety-seven patients underwent forehead flap reconstruction, with a mean age of 68.5 years. Mean follow-up time was 42 months. There were 50 (25.4%) patients who developed a complication, including impaired nasal function (18.8%), flap congestion (5.1%), infection (2.5%), poor donor site healing (2.5%) wound dehiscence (2.0%), and flap congestion (1.5%). On univariate analysis, female sex, immunosuppression, prior radiotherapy, and larger resection area were associated with complications ( P <0.05). On multivariable analysis, female sex [odds ratio (OR): 3.89, P <0.001], hypoalbuminemia (OR: 3.70, P =0.01), and prior wide local excision (OR: 3.62, P =0.04) were predictors of complications. A clinical calculator was developed incorporating these risk factors, with a C-statistic of 0.85, indicating strong predictive value. CONCLUSIONS: We conducted the most comprehensive review of risk factors for the development of complications after forehead flap reconstruction. From this analysis, a novel, implementable, risk-stratification scheme was developed to equip surgeons with the ability to provide individualized risk assessment to patients and address preoperative comorbidities to optimize outcomes.

Optimizing Blood Loss and Management in Craniosynostosis Surgery: A Systematic Review of Outcomes Over the Last 40 Years.

Surgical correction of craniosynostosis can involve significant blood loss. Rates of allogenic blood transfusion have been reported to approach 100%. Multiple interventions have been described to reduce blood loss and transfusion requirements. The aim of this study was to analyze various approaches over the last 4 decades to optimize blood loss and management during craniosynostosis surgery.PRISMA guidelines for systematic reviews were followed. PubMed and Cochrane database searches identified studies analyzing approaches to minimizing blood loss or transfusion rate in craniosynostosis surgery.Primary outcomes included rate or amount of allogenic or autologous blood transfusion, estimated blood loss (EBL), postoperative hemoglobin (Hg), or hematocrit (Hct) levels. Secondary outcomes were examined when reported.Fifty-two studies met inclusion criteria. There was marked heterogeneity regarding design, inclusion criteria, surgical intervention, and endpoints. The majority of the studies were nonrandomized and noncomparative. Four studies analyzed erythropoietin (EPO), 6 analyzed various cell-saver (CS) technologies, 18 analyzed antifibrinolytics (tranexamic acid [TXA], aminocaproic acid [ACA], and aprotinin [APO]), 8 analyzed various alternatives, and 16 analyzed multimodal pathways & protocols. Some studies analyzed multiple approaches.Although the majority of studies reviewed represent level III/IV evidence, several high-quality level I studies were identified and included. Level I evidence supported an improvement in blood outcomes by utilizing EPO, CS, and TXA, individually or in concert with one another. Thus, this review suggests that a multi-prong approach may be the most effective means to optimize blood loss and transfusion outcomes in craniosynostosis surgery.

The Influence of Age on Complications After Correction of Congenital Breast Deformities: A National Analysis of the Pediatric and Adult NSQIP Data Sets.

BACKGROUND: Timing of surgical intervention is controversial among patients seeking correction of congenital breast deformities. OBJECTIVES: This study aimed to assess the influence of age on 30-day complications and unplanned healthcare utilization after reconstruction of congenital breast deformities. METHODS: Female patients undergoing breast reconstruction for congenital breast deformities and Poland syndrome were identified on the basis of International Classification of Diseases (ICD) codes in the 2012 to 2021 pediatric and adult National Surgical Quality Improvement Project (NSQIP) data sets. Complications based on age at correction were compared, and multivariate logistic regression was used to identify predictors of overall and wound healing complications. RESULTS: Among 528 patients meeting inclusion criteria, mean (SD) age at surgical correction was 30.2 (13.3) years. Patients most commonly underwent implant placement (50.5%), mastopexy (26.3%), or tissue expander placement (11.6%). Across the cohort, overall incidence of postoperative complications was 4.4%, most commonly superficial surgical site infection (1.0%), reoperation (1.1%), or readmission (1.0%). After multivariate adjustment, increasing age at time of correction was associated with higher incidence of wound complications [odds ratio (OR) 1.001; 95% confidence interval (CI) 1.0003-1.002; P = .009], in addition to BMI (OR 1.002; 95% CI 1.0007-1.004; P = .006) and tobacco use (OR 1.06; 95% CI 1.02-1.11; P = .003). CONCLUSIONS: Breast reconstruction for congenital breast deformities may be safely undertaken at a young age with a low associated risk of postoperative complications. Large, multi-institutional studies are needed to assess the influence of surgical timing on psychosocial outcomes in this population.

Youngest Composite Full-Face Transplant: A Model for Vascularized Composite Allograft in Younger Populations.

BACKGROUND: The field of face transplantation continues to evolve, with more complex defects being addressed, and, at the same time, increased outcome expectations. Given our unique long-term experience in this field, we consented one of the youngest patients to undergo a full-face transplant. METHODS: An 18-year-old woman presented with complete destruction of her central face and craniofacial structures. She had coexisting major injuries, including pituitary gland, visual axis, and motor control. After extensive rehabilitation and reconstruction techniques, the patient underwent face transplant on May 4, 2017, at the age of 21 years. RESULTS: The total operative time for the recipient was 26 hours. There were no major perioperative complications. Since transplant, the patient has undergone 3 revision surgeries. She is near completely independent from a daily life activity standpoint. She has had 1 episode of rejection above grade II that was successfully treated with a short-term increased in immunosuppression. CONCLUSIONS: Contrary to data in solid organ transplantation where youth is associated with increased risk of rejection, our current algorithm in immunosuppression, combined with this patient's compliance, has led to only 1 rejection episode beyond grade II. This successful transplant can serve as a model for future vascularized composite transplants in younger populations.

The role of topical probiotics in skin conditions: A systematic review of animal and human studies and implications for future therapies.

There is increasing evidence that the intestinal microbiome plays an important role in modulating systemic inflammation and disease. Oral probiotics can modulate the intestinal microbiome and have demonstrated to be efficacious in treating topical skin conditions, such as atopic dermatitis, acne and rosacea. By proxy, exogenous application to the skin of probiotics should also promote a positive bacterial balance to mitigate or potentially eliminate pathologic conditions. The goal of this article was to provide a systematic review of studies that have investigated the role of topical probiotics in mitigating skin conditions. Additionally, skin conditions where dysbiosis has been identified but topical probiotics have not been investigated are discussed. We hope this review both analyses the evidence for the role that topical probiotics could play in topical skin conditions and highlights additional areas in need of research and exploration.

Collaboration between breast and reconstructive surgery in optimizing outcomes for women with breast cancer.

Performing successful breast reconstruction after mastectomy requires communication and collaboration between the breast and reconstruction surgery teams. This allows for oncologic safety while providing esthetic and functional reconstruction. In this article, we discuss the numerous techniques we have adopted successfully into our breast reconstructive practice that were possible due to this collaboration including prophylactic lymphaticovenous bypass (LVB), tumor ultrasound-guided incision (TUGI), esthetic closure in patients not eligible or desiring reconstruction, nerve identification at time of mastectomy to allow for sensate reconstruction, and the prevention of chronic pain and strategic oncoplasty.

Congenital breast deformities: Anatomical basis and surgical approaches for optimal aesthetic outcomes.

Plastic surgeons routinely encounter patients desiring correction of breast asymmetry, hypoplastic growth, or other aesthetic concerns. An appropriate recognition of congenital breast conditions is critical for plastic surgeons. Without consideration of underlying anatomical abnormalities in these patients, surgical intervention may not result in optimal aesthetic outcomes. Often, patients are unaware of their congenital condition and the limitations and difficulties associated with reconstruction must be discussed with the patient preoperatively to ensure optimal aesthetic outcomes. The goal of this article was to summarize the anatomical basis for common congenital breast conditions and discuss options for surgical correction based on the literature and our experience.

Technical considerations in nonreconstructive mastectomy patients.

BACKGROUND: Not all women undergo post-mastectomy breast reconstruction due to medical comorbidities or personal preference. An aesthetically pleasing closure and contour of the chest wall is still desired, though may be technically difficult to achieve in some patients. By combining techniques and lessons learned from breast reductions and female-to-male mastectomies (FTTM), we present a technical approach to aesthetic primary closure post-mastectomy that can be utilized in patients regardless of preoperative breast size. METHODS: After mastectomy, excess cranial/caudal tissue is determined and the lower flap is de-epithelialized to allow for bulk in the reconstructed breast. Excess tissue in the horizontal plane is assessed, and axillary, nonbreast tissue is medialized. Excess skin in the horizontal plane is removed with a small lateral incision similar to a wise-pattern closure. RESULTS: We have performed this technique with good aesthetic results and satisfied patients postoperatively. CONCLUSION: When performing post-mastectomy closure without reconstruction, attention to tissue excess, medialization of axillary tissue and providing bulk with lateral and caudal tissue allows for an easy, reproducible, and aesthetic closure.

Perioperative Homeopathic Arnica and Bromelain: Current Results and Future Directions.

INTRODUCTION: Arnica and bromelain, two of the most widely recommended homeopathic medications to improve perioperative outcomes, have yet to be widely adopted by allopathic practitioners. A significant barrier to utilization of herbal medications by allopathic doctors is that the preparations and dosing regimens are not widely known or understood. The goal of this review was to critically analyze studies that have examined the perioperative efficacy of arnica and bromelain with a focus on treatment regimen and outcomes. METHODS: A triple database search was conducted with the keywords "arnica," "bromelain," and "surgery." References for each identified article were analyzed for additional articles. Articles were analyzed for methodology, outcomes, and conclusion. Articles were excluded if they did not involve human subjects, were published before 1990, and if they were not available in English. Level of evidence was determined based on methodology. RESULTS: A total of 29 articles met inclusion criteria, with 20 and 9 in the arnica and bromelain treatment groups, respectively. There was marked heterogeneity with regard to surgical procedure, dosing regimen, outcomes measured, and results. Arnica seems to have a mitigating effect on ecchymosis, most notably following rhinoplasty and facelifts/facial procedures. Bromelain is well supported across numerous studies in reducing trismus, pain, and swelling following molar extractions. However, there was no effect demonstrated when evaluating topical arnica following blepharoplasty procedures. DISCUSSION: A systematic review of the literature demonstrates the potential for arnica and bromelain to improve perioperative outcomes including edema, ecchymosis, and pain control. Future studies are required to determine safety and efficacy of dosing and interactions with other medications. We hope this article stimulates surgeons to consider using these interventions to improve perioperative outcomes in the context of well-done studies with an objective analysis of results.

Characterization of Face Transplant Candidates Evaluated at Cleveland Clinic and Algorithm to Maximize Efficacy of Screening Process.

INTRODUCTION: As a high-volume referral center for facial transplantation, we have learned significantly from the screening, evaluation, and enrollment process. This report analyzes our algorithm for the assessment of potential face transplant candidates referred to our institution. METHODS: After institutional review board approval in 2004, a prospectively maintained database was created for patients who were referred face transplant. Records were reviewed for the nature of tissue defect, functional deficit, surgical and medical history, and expert recommendations.Our algorithm begins with a review of a patient's file with a focus on institutional review board criteria. After screening, a phone interview is conducted, and transplantation is discussed. Patients are presented to the team to analyze the medical, psychiatric, and surgical history; support network; and geographic location. Eligible patients are invited for an in-person evaluation, and the case is reviewed again with the team. If approved, the patient can provide consent for transplantation. RESULTS: More than 200 patients were referred for transplant evaluation at the Cleveland Clinic from 2004 to 2016. Sixty were eligible for further evaluation for face transplantation based on preliminary screening. Thirteen (6.5% of original cohort) were invited for in-person evaluation and physical examination. Five (2.5% of original cohort, 38.4% invited cohort) of these 13 patients underwent face transplantation, of whom, 3 (1.5% of original cohort, 23.1% invited cohort) underwent face transplantation at our institution. All 3 patients who were ultimately transplanted were referred by a physician. DISCUSSION: As the availability of public information on face transplant increases, it is likely that an increase in self-referral for face transplantation will occur. Thus, it is critical that institutions adopt a systematic approach to triage in order to identify appropriate patients. Our algorithm allowed for a high enrollment and transplantation ratio to save patient and institution time and resources. This could be easily adopted by other institutions to save time, money, and resources.

Revisiting the "July Effect" in Plastic Surgery: New Data to Support Resident Autonomy.

BACKGROUND: The "July Effect" represents a topic of considerable interest across residency programs. This study investigated the frequency of postoperative complications following procedures with plastic surgery resident participation (all postgraduate year [PGY] levels) during the first (quarter 3, July-September) and last academic quarters. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was used to calculate complication rates from 2006 to 2010. Resident involvement was analyzed as a categorical variable consisting of "juniors" (PGY1-PGY3), and "seniors" (PGY4-PGY6). Outcomes from procedures during Q3 were compared with all quarters. Propensity score matching and adjustment enabled logistic regression identifying the effect of resident involvement and admission. RESULTS: Among all cosmetic and reconstructive procedures (n = 6625), mean operative time was not significantly greater in Q3 compared with all other quarters (P = 0.069); no significant differences in complication rates were observed between Q3 and all other quarters, though superficial surgical site infection (SSI) approached significance (3.3% of procedures in Q3 vs 2.5% in all other quarters, P = 0.063). Among reconstructive procedures only (n = 5677), mean operative time was not significantly greater in Q3 compared with all other quarters (P = 0.119); the same held true for cosmetic procedures only (P = 0.275). Surgical site infection, however, was significantly more likely to occur with reconstructive procedures only, in Q3 compared with all other quarters (3.5% of cases vs 2.3%, P = 0.024). When adjusting for PGY status and matching populations, superficial SSI and return to the operating room were not significantly more common in Q3. When adjusting for quarter of admission, however, superficial SSI was significantly more common among the overall and noncosmetic cases with participation by junior residents (P = 0.013 and 0.020, respectively). CONCLUSIONS: This may represent the first fully reproducible, transparent National Surgical Quality Improvement Program study in plastic surgery that demonstrates the absence of a clinically significant "July Effect," and suggests that an appropriate degree of resident autonomy may pose minimal risk during both cosmetic and reconstructive procedures in residency training. Additionally, the findings encourage the development a plastic surgery-specific database to remedy inherent difficulties with larger, more comprehensive surgical databases.

Optimizing Postoperative Pain Control in Autologous Breast Reconstruction: A Systematic Review.

BACKGROUND: Pain management approaches in autologous breast reconstruction have become a topic of great interest in the era of enhanced recovery after surgery protocols, as well as the opioid epidemic. The management of postoperative pain is of critical importance for women undergoing breast reconstruction; however, these protocols have yet to be synthesized and compared in the primary literature. Herein, we present a systematic review of approaches to provide optimal pain control while minimizing narcotic use and its associated potential negative sequelae in autologous breast reconstruction. METHODS: A comprehensive systematic review of the published literature was conducted using Ovid Medline/PubMed database without timeframe limitations, in compliance with the guidelines outlined in the Preferred Reporting Items for Systematic reviews and Meta-Analyses. Inclusion criteria were selected for studies reporting objective outcomes of pain modulation in autologous breast reconstruction. Articles for inclusion were stratified based on intervention. RESULTS: A total of 101 articles were identified on initial search query. After full-text review and final screening of all articles and review of included studies' references, 28 studies met the inclusion criteria and were analyzed. CONCLUSION: There continues to be a substantial need for evidence-based guidelines in the plastic surgery literature. Mitigating postoperative pain can improve health-related quality of life, reduce health care resource utilization and costs, and minimize perioperative opiate use. Given the increasing popularity of and access to autologous approaches to breast reconstruction, we hope this area of study continues to be a top priority for plastic surgeons to allow for optimized postoperative care.

The role of topical probiotics on wound healing: A review of animal and human studies.

Pathogenic, opportunistic, and commensal bacterial coexist in the intestinal tract, and imbalances among these strains have been linked to systemic inflammation and a variety of disease states. Similarly, human skin plays an important role as an interface between the body and the environment with an estimated 1 billion microbes per square centimetres. Skin microbiome fluctuations that cause increases in pathologic bacteria, either because of individual and/or environmental factors, can lead to disease states at the skin level ranging from inflammatory conditions to infections. As wounds are inherently associated with perturbations in the local microflora due to injury and activation of the immune responses, the addition of topical probiotics could be a means to prevent infection, regulate inflammation, and potentially augment healing. The goal of this review is to analyse the impact the skin microbiome has on cutaneous wound healing with a focus on developing proposed treatment algorithms and support for their therapeutic potential.

Indocyanine Green Fluorescence Imaging with Lymphoscintigraphy for Sentinel Node Biopsy in Melanoma: Increasing the Sentinel Lymph Node-Positive Rate.

INTRODUCTION: The goal of this study was to analyze patients who underwent a sentinel lymph node biopsy (SLNB) in melanoma with the combination of radioisotope lymphoscintigraphy and indocyanine green (ICG) fluorescence imaging to compare our true positive (TP) rate, a means to perform immediate analysis of the SLNB, with that of the literature. METHODS: Consecutive cutaneous melanoma patients who underwent SLNB with lymphoscintigraphy and ICG-based fluorescence imaging by the senior author (BG) from 2012 to 2018 were prospectively enrolled. The average expected SLN-positive rate per T stage was calculated based on three studies and compared with our SLN-positive rate. RESULTS: Overall, 574 consecutive patients were analyzed. Average Breslow thickness was 1.9 mm. A total of 1754 sentinel nodes were sampled; 1497 were identified by gamma probe signaling and ICG, 241 were identified by gamma probe signaling only, and 16 were identified by ICG only. There were 123 (21.4%) patients with at least one positive SLN; 113 (91.9%) had at least one positive node identified with both gamma probe signaling and ICG, 8 (6.5%) had positive node(s) identified with gamma probe signaling only, and 2 (1.6%) had positive node(s) identified with ICG only. There was an overall 21.4% SLN-positive rate, with 8% T1, 18.5% T2, 41.1% T3, and 52.4% T4, which is higher than the predicted rates for each stage. CONCLUSIONS: With the largest cohort of patients reported who underwent a melanoma SLNB with lymphoscintigraphy and ICG, we demonstrated that this technique results in higher SLN-positive rates than predicted. Patients are being followed but, given the TP data, knowledge of our results may foster the use of this modality to improve staging and treatment options.

Axillary reverse mapping and lymphaticovenous bypass: Lymphedema prevention through enhanced lymphatic visualization and restoration of flow.

BACKGROUND: A lymphedema (LE) prevention surgery (LPS) paradigm for patients undergoing axillary lymphadenectomy (ALND) was developed to protect against LE through enhanced lymphatic visualization during axillary reverse mapping (ARM) and refinement in decision making during lymphaticovenous bypass (LVB). METHODS: A retrospective analysis of a prospective database was performed evaluating patients with breast cancer who underwent ALND, ARM, and LVB from September 2016 to December 2018. Patient and tumor characteristics, oncologic and reconstructive operative details, complications and LE development were analyzed. RESULTS: LPS was completed in 58 patients with a mean age of 51.7 years. An average of 14 lymph nodes (LN) were removed during ALND. An average of 2.1 blue lymphatic channels were visualized with an average of 1.4 LVBs performed per patient. End to end anastomosis was performed in 37 patients and a multiple lymphatic intussusception technique in 21. Patency was confirmed 96.5% of patients. Adjuvant radiation was administered to 89% of patients. Two patients developed LE with a median follow-up of 11.8 months. CONCLUSION: We report on our experience using a unique LPS technique. Refinements in ARM and a systematic approach to LVB allows for maximal preservation of lymphatic continuity, identification of transected lymphatics, and reestablishment of upper extremity lymphatic drainage pathways.

Gene expression profiling in melanoma: past results and future potential.

The field of melanoma oncology is rapidly evolving with advances in detection, staging and treatment. There is heterogeneity in all stages of melanoma where some patients fare better than others for reasons currently unknown and it is sometimes unclear which patients warrant closer surveillance, multidisciplinary care, increased imaging, more aggressive surgery or adjuvant therapy. Early studies have shown the predictive ability of gene expression profiling (GEP) and institutions that have adopted GEP for melanoma treatment have demonstrated changes in practice patterns and patient management. The goal of this paper is to review the clinical evidence for a new diagnostic test, DecisionDx-Melanoma, the only GEP test for cutaneous melanoma with prospective studies analyzing its utility.

Collaboration between the breast and plastic surgeon in restoring sensation after mastectomy.

Breast cancer is the most commonly diagnosed invasive cancer in women worldwide. While hypoesthesia is a known sequela after mastectomy, patients are now inquiring with renewed interest about the degree and timing of sensation after mastectomy. This is a topic that has generated much research interest. However, while there have been advances in the field, there are few, well-done studies that allow for an accurate answer to this question. In this article, relevant breast and donor site anatomy is reviewed for sensate autologous breast reconstruction. Additional donor sites apart from the typically utilized abdomen are analyzed with relevant anatomical discussions. Outcomes are presented; however, due to the heterogeneity of the patient population, surgical approach and postoperative sensory testing, it is difficult to compare results between studies. Future directions and unanswered questions regarding sensate autologous breast reconstruction are highlighted. While great strides have been made in providing sensate autologous breast reconstruction, there are still many unanswered questions. Thus, the collaboration between surgical teams and sharing of outcomes is crucial to allow for optimization of this powerful surgical approach.

Anatomic Targets for Breast Reconstruction Neurotization: Past Results and Future Possibilities.

The concept of providing neurotized autologous breast reconstruction is not novel, but the introduction of cadaveric nerve grafts has allowed for the development of new techniques and a resurgence in academic interest. There has been a surge in the number of publications regarding neurotized autologous breast reconstruction. However, recent articles and reviews have focused mainly on autologous, abdominal-based reconstruction. The sensory innervation of the most commonly used autologous tissues has been well described, allowing surgeons to perform accurate and reproducible dissections. However, there are numerous options for autologous breast reconstruction, and not all patients are candidates for abdominally based reconstruction. As more patients inquire to their possible reconstruction options, plastic surgeons will have to be well versed in the different neurotized options and appreciate the technical aspects associated with reconstructive success. In this review, we aim to discuss both established anatomic targets for autologous flap neurotization and future directions.

A literature review and meta-analysis of outcomes in microsurgical reconstruction using vasopressors.

INTRODUCTION: There is a hesitancy to utilize vasopressors in microsurgical reconstruction due to fear of vessel spasm and subsequent flap compromise. Although there are large literature reviews analyzing vasopressor usage in head and neck reconstruction, this has not been extrapolated to all regions of the body. The goal of this study was to perform a meta-analysis examining vasopressor usage and risk of complications in microsurgical reconstruction for all recipient sites. MATERIALS AND METHODS: A meta-analysis was conducted for articles discussing the utilization of vasopressors in microsurgical reconstruction. The primary endpoint was total flap failure. Secondary endpoints were necessity for operative take-back and hematoma requiring intervention. Odds ratios were calculated for each complication and for each study. RESULTS: Four prospective and six retrospective studies were analyzed yielding 6321 patients and 7526 flaps. 67.4% (966/1433) of patients received vasopressors and 80.8% (6080/7526) of flaps received vasopressors. There were 100 failures in the vasopressor group (100/6080 = 15.9%) and 39 failures in the non-vasopressor group (39/1456 = 26.8%) (O.R. 0.73; p = 0.12). There were 177 take-backs in the vasopressor group (177/5916 = 29.9%) and 64 take-backs in the non-vasopressor group (64/1404 = 4.6%) (O.R. 0.65; p < 0.05). There were 73 hematomas in the vasopressor group (73/5099 = 14/3%) and 14 hematomas in the non-vasopressor group (14/979 = 14.3%) (O.R. 1; p = 0.89). The odds ratio for total flaps failures in the breast and head/neck cohorts were 0.788 (p = 0.76) and 1.2761 (p = 0.77), respectively, with neither significantly increased in flaps receiving vasopressors. CONCLUSION: Our results suggest that vasopressor utilization does not directly result in increased complications. Flaps that received vasopressors had a statistically lower rate of take-back and failure. Due to the paucity of data available for analysis and limited reporting relating flap characteristics to outcomes, prospective, well-designed studies are necessary to verify the safety of vasopressor use in microsurgical reconstruction.

Challenges in Microsurgical Reconstruction for Craniofacial Osteomyelitis With Resultant Osteonecrosis.

INTRODUCTION: Chronic osteomyelitis is characterized by compromised blood supply and eventual osteonecrosis. Definitive treatment requires aggressive resection of affected bone. The resultant defect poses a unique challenge to reconstructive surgeons. Much of the literature on craniofacial osteomyelitis focuses on infection eradication, rather than subsequent reconstruction. This article reports representative cases from our experience with free flap reconstruction for defects secondary to chronic osteomyelitis of the craniofacial skeleton. METHODS/RESULTS: The authors selected 5 of the most difficult reconstructive cases of craniofacial osteomyelitis from our experience in a single tertiary referral institution with a follow-up of at least 6 months. Three of the 5 cases arose in the setting of previous head and neck cancer treated with resection and radiation therapy. One case had a previous surgical craniotomy complicated by osteomyelitis and multiple failed alloplastic reconstructions. The final case was due to multiple gunshots to the head, with subsequent cerebral and cranial abscess (>1000cc). In each case, the defect was successfully treated with free tissue transfer. Two cases required creation of recipient vessels with an arteriovenous loop. CONCLUSIONS: Free tissue transfer provides a versatile and effective tool in the reconstruction of extensive craniofacial osteomyelitis defects. Furthermore, the addition of vascularized tissue can protect against further episodes of osteomyelitis. Finally, arteriovenous loops can be employed successfully when prior radiation and infection of the wound bed precludes the use of local recipient target vessels.
