Huang RS, Benour A, Wong Riff KWY. Survival and infection rates of microvascular free flaps in pediatric mandibular reconstruction: A systematic review and meta-analysis. Microsurgery 2024; 44:e31200. [PMID: 38828556 DOI: 10.1002/micr.31200] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2024] [Revised: 04/08/2024] [Accepted: 05/16/2024] [Indexed: 06/05/2024]
Abstract
BACKGROUND Vascularized free tissue transfer has been established as an effective method in the reconstruction of mandibular defects. However, a limited understanding of its efficacy in pediatric patients persists due to its infrequent presentation. The aim of this study is to systematically consolidate the survival and infection rates of free flaps in pediatric mandibular reconstruction. METHODS A systematic literature search was conducted on Ovid Medline, Embase, and Cochrane Library for studies published up to January 2024. We included peer-reviewed studies reporting on survival and infection outcomes associated with free flap mandibular reconstruction in pediatric patients (<18 years). We performed a random-effects meta-analysis with the inverse-variance weighted approach to estimate survival and infection rates. Heterogeneity was assessed by I2, and publication bias was examined using Egger's test. RESULTS A total of 26 studies, reporting on 463 free flaps and 439 pediatric patients with a mean age of 10.7 years, were included in our study. Most free flaps originated from the fibula (n = 392/463, 84.7%) and benign tumors were the most common cause for mandibular reconstruction (n = 179/463, 38.7%). The pooled estimate for survival of flaps was 96% (95% CI: 93-97, I2 = 0%), and recipient-site infections were estimated to occur in 9% (95% CI: 6-13, I2 = 0%) of cases. The most common reported complications within the study timeframe were early malocclusion (n = 28/123, 21.4%) and bite abnormalities (18/131, 13.7%). CONCLUSION Free tissue transfer for mandibular reconstruction in pediatric patients is effective and safe. Further research is required to explore functionality following mandibular reconstruction in diverse pediatric populations.

Maxillofacial Microvascular Free-Flap Reconstructions in Pediatric and Young Adult Patients-Outcomes and Potential Factors Influencing Success Rate. J Clin Med 2024; 13:2015. [PMID: 38610780 PMCID: PMC11012962 DOI: 10.3390/jcm13072015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2024] [Revised: 03/16/2024] [Accepted: 03/27/2024] [Indexed: 04/14/2024] Open
Abstract
Background: Maxillofacial microvascular free-flap reconstructions are significant interventions in the management of congenital defects, traumatic injuries, malignancies, and iatrogenic complications in pediatric and young adult patients. Craniofacial disorders within this demographic can result in profound functional, cosmetic, and psychosocial impairments, highlighting the critical need for thorough investigation into factors that may influence procedural success and postoperative quality of life. This retrospective chart review aims to examine the outcomes and potential influencing factors, aiming to offer valuable insights into optimizing the effectiveness of these reconstructions and improving patient outcomes. Methods: A single head and neck surgical team performed all the included 136 procedures. Demographic and surgical patient data were recorded. Type of transfer performed in each recipient site and major complications were analyzed. Relevant influencing factors, such as age, gender, and etiology of defect were determined using the ANOVA test and χ2 test of independence. Results: The results indicate a 90% success rate. No significant relationship was found between the incidence of total flap loss and patient age, etiology, or graft source. The maxillary reconstructions showed a higher incidence of total flap loss compared to mandibular reconstructions (11 vs. 3 cases). Conclusions: Despite the high success rate, the findings underline the necessity for further research to validate these observations and enhance surgical methods for pediatric and young adult patients.

Abstract
There is minimal information regarding free tissue transfers in very young infants, especially those less than a year old. It is often thought that that age remains a limit to free tissue transfers, with younger patients having smaller vessels, making the operation technically challenging. In this case report, we discuss the youngest and smallest recorded case of a free flap reconstruction. A 3-month-old patient with a malignant parapharyngeal undifferentiated round cell sarcoma underwent a resection and reconstruction with a radial forearm free flap (RFFF). The defect was 35 by 20 by 15 mm, and required a pharyngeal "patch," as opposed to a "tube," reconstruction. The defect was templated, and the RFFF then raised in a standard subfascial fashion, and inset with resorbable sutures. The patient was observed in the ICU postoperatively. The patient was subsequently diagnosed with Stage IV primary undifferentiated sarcoma with regional metastasis and received adjuvant chemotherapy. Fifteen-month follow up revealed no signs of recurrence, full oral intake, a well-reconstructed pharynx on nasoendoscopic examination, and minimal donor site morbidity. This report illustrates several unique adaptations of free flap transfer in infants and adds to the emerging body of evidence that age is not a contraindication for head and neck reconstruction.

Abstract
BACKGROUND The purpose of this study was to evaluate the long-term outcomes of mandibular reconstruction with vascularized free fibula flap in pediatric patients. METHODS Consecutive cases of mandibular reconstruction with vascularized free fibula flaps in pediatric patients at Peking University School and Hospital of Stomatology between 1999 and 2019 were reviewed. Postoperative computed tomography (CT) data of all patients were collected at each postoperative follow-up point, and after the age of 18 years. The length and height of the grafted fibula and the length of the remaining mandible were evaluated by measuring the three-dimensional CT data using ProPlan CMF 3.0 software. Lower limb function was evaluated using the Enneking evaluation scale. Facial symmetry was self-evaluated and scored. Statistical analysis was performed on the data obtained. RESULTS Fourteen patients were included in this study. All flaps were successful. The CT measurement results showed growth in the length of the grafted fibula that reconstructed the mandibular ramus and the residual mandible ( P < 0.05). The height of the grafted fibula remained stable ( P > 0.05). Eight patients were followed up until they were older than 18 years, and the CT measurement results after 18 years showed an essentially symmetric mandible profile ( P > 0.05). All patients were satisfied with their postoperative facial symmetry. Enneking evaluation scores showed good recovery of lower limb functions. CONCLUSIONS The vascularized free fibula flap for mandibular reconstruction in pediatric patients is safe and reliable. It also provides good cosmetic and functional outcomes, as it demonstrated positive growth. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
BACKGROUND Periosteum-mediated bone regeneration (PMBR) is a recognized method for mandibular reconstruction. Despite its unpredictable nature and the limited degree to which it is understood, it does not share the concerns of developmental changes to donor and recipient tissues that other treatment options do. The definitive role of the periosteum in bone regeneration in any mammal remains largely unexplored. The purpose of this study was to identify the genetic determinants of PMBR in mammals through a systematic review. METHODS Our search methodology was designed in accordance with the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) guidelines. We conducted a quality assessment of each publication, and evaluated the differences in gene expression between days 7 and 15. RESULTS A total of four studies satisfied the inclusion criteria. The subjects and tissues examined in these studies were Wistar rat calvaria in two studies, mini-pigs in one study, and calves and mice in one study. Three out of the four studies achieved the necessary quality score of ≥ 3. Gene expression analysis showed increased activity of genes responsible for angiogenesis, cytokine activities, and immune-inflammatory responses on day 7. Additionally, genes related to skeletal development and signaling pathways were upregulated on day 15. Conclusions: The results suggest that skeletal morphogenesis is regulated by genes associated with skeletal development, and the gene expression patterns of PMBR may be characterized by specific pathways.

Abstract
A free fibular flap is commonly used in adult mandibular reconstruction; however, its use in the pediatric population is not strongly supported. The authors are reporting the long-term update of a case of a pediatric patient who underwent a mandibular reconstruction using a free fibular flap after a resection of mandibular desmoid fibromatosis. Greatest growth was objectively measured and demonstrated at the condyle using a 3-dimensional model generated from Materialise software. This is 1 case and subsequent studies should be observed to further elucidate the full growth potential of the mandible in pediatric patients undergoing mandibular reconstruction.

Abstract
BACKGROUND Microsurgical free tissue transfer has been successfully implemented for various reconstructive applications in children. The goal of this study was to identify the best available evidence on perioperative management of pediatric patients undergoing free tissue transfer, and use it to develop evidence-based care guidelines. METHODS A systematic review was conducted in Pubmed, Embase, Scopus, and Cochrane Library databases. Since a preliminary search of the pediatric microsurgical literature yielded scant data with low level of evidence (LOE), pediatric anesthesia guidelines for healthy children undergoing major surgeries were also included. Exclusion criteria included: vague descriptions of perioperative care, case reports, and studies of syndromic or chronically ill children. RESULTS 204 articles were identified, and 53 met inclusion criteria. Management approaches specific to the pediatric population were used to formulate recommendations. High quality data was found for anesthesia, analgesia, fluid administration / blood transfusion, and anticoagulation (LOE 1). Lower quality evidence was identified for patient temperature (LOE 3) and vasodilator use (LOE 4). Key recommendations include: administering sevoflurane for general anesthesia, implementing a multimodal analgesia strategy, limiting preoperative fasting, restricting blood transfusions until hemoglobin < 7 g/dl unless patient is symptomatic, and reserving chemical venous thromboembolism prophylaxis for high risk patients. CONCLUSIONS Pediatric-specific guidelines are important as they acknowledge physiologic differences in children, which may be overlooked when extrapolating from adult studies. These evidence-based recommendations are a key first step toward standardization of perioperative care of pediatric patients undergoing plastic surgical procedures, including free tissue transfer, to improve outcomes and minimize complications.

Outcomes following Microvascular Mandibular Reconstruction in Pediatric Patients and Young Adults. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2020; 8:e3243.

Abstract
Background: The etiology and treatment of complex mandibular defects in children differ markedly from those of adults, although treatment with free bone flaps is historical in both groups. While adult outcomes and complication rates are well known, few pediatric data exist, especially for patients with congenital deficiencies. This study reports early and late outcomes from a cohort of young, primarily syndromic patients undergoing microvascular mandibular reconstruction. Methods: This is a retrospective case series of patients who underwent microvascular mandibular reconstruction between 1995 and 2016. Results: Thirteen patients received a total of 13 fibula transfers and 1 medial femoral condyle transfer. Most patients carried a congenital diagnosis (77%), and the average age during surgery was 11.7 ± 5.7 years. The median (interquartile range) [IQR] length of follow-up was 6.3 (5.7) years. There was a 100% flap survival rate, although 86% of all patients experienced at least one complication. Half of all procedures resulted in an early complication. Nine patients (69%) developed late complications, of which temporal mandibular joint ankylosis was the most common (n = 5; 38%). Conclusions: This study is one of few detailing outcomes following mandibular reconstruction by free flap transfer in pediatric patients. These patients were primarily syndromic with appreciable complication rates higher than in other adult and pediatric studies. Some complications are manageable or self-resolving, but others lead to functional problems that may require late operative interventions to correct. Microsurgical treatment should be reserved for children with large, complex mandibular defects when other options are unavailable or have been exhausted.

Abstract
OBJECTIVES Reconstruction of surgical defects by free tissue transfer following resection of head and neck tumors in children are sparse. This study aims to assess the feasibility and safety of free flap reconstruction following surgical ablation of head and neck and skull base tumors in children based on our experience and the recent literature. METHODS Data from medical files of all children and adolescents <18 years of age who underwent free flap reconstruction following resection of head and neck and skull base tumors at our tertiary center between 2000 and 2018 were retrospectively reviewed. Data on early and late complications at the primary and donor sites, functional and aesthetic outcome, and tumor control were analyzed. RESULTS Twenty-four children (mean age 11.3 ± 5.1 years) were enrolled. Early complications occurred in 14 (56%) and late complications occurred in 8 (32%) of the procedures, with surgical intervention required in 4 (16%). Prior chemoradiation, sarcoma, non-reanimation procedures, and the use of rectus abdominis free flaps were associated with higher complication rates. The final functional and cosmetic outcomes, including mastication, deglutition, and speech, were satisfactory in all patients with one exception. CONCLUSIONS Free flap transfer is a safe and feasible technique for reconstructing head and neck and skull base defects following surgical excision of tumors in children. Early identification and precautionary measures against the effects of potential causes of complications may improve outcome. Larger international cohort studies are warranted.

Abstract
INTRODUCTION The free fibula flap (FFF) is a preferred option for adult mandibular reconstruction. Due to skeletal immaturity, its routine use in pediatric patients remains in question. Inconsistencies regarding the ability of the FFF to grow in concordance with the patients' natural growth currently exist in the literature. The purpose of this report is to quantify mandibular growth in a young patient undergoing partial hemi-mandibular reconstruction with a FFF utilizing advanced three-dimensional software. METHODS A 2-year old underwent left hemi-mandibular reconstruction with a FFF following resection of a desmoid tumor. The condyle was preserved. Using 3D software, changes in mandibular growth and morphology were evaluated based on preoperative (2.1 years old) and postoperative (2.5 years and 5.2 years old) computed tomography imaging. RESULTS Mandibular growth occurred throughout the mandible in both postoperative evaluations. Greatest growth was seen in the ramus height. Fibula growth was also seen when comparing measurements to the virtual surgical planning guide. A novel parts comparison analysis revealed the greatest growth potential occurred at the condyle. CONCLUSION Providing an objective evaluation using 3D software, we have demonstrated growth throughout the reconstructed mandible, with greatest growth occurring at the preserved condyle. Despite scientific limitations of our study, the potential for mandibular growth appears to remain after FFF reconstruction, offering successful functional and cosmetic outcomes.

Abstract
Free flap reconstruction after resection in paediatric patients with head and neck cancer (HNC) has various clinical challenges, which have not yet been fully investigated. This retrospective study was implemented to investigate these factors. Paediatric patients (≤14 years old) who underwent free flap reconstructions following surgery for HNC at a tertiary referral centre during the years 2009-2018 were included. Clinical, pathological, and imaging data were collected and analysed. Overall, 47 patients were included, 26 male and 21 female. Thirty-four patients were ASA status I and 13 were ASA status II. The median operative time was 415 minutes, while the median intraoperative blood loss was 500 ml. Seventeen patients had a tracheotomy. Fourteen medical complications (six pulmonary infection, six diarrhoea, two pulmonary aspiration) and six surgical complications (one haematoma beneath flap, two wound dehiscence, one salivary fistula, one effusion, one tracheotomy haemorrhage) were observed. Tracheotomy was associated with medical complications (P = 0.003) and total complications (P = 0.024). It was confirmed that microvascular reconstruction can be adopted in paediatric HNC patients, while tracheotomy and nasal feeding tubes should be used with caution. Comprehensive preoperative assessment, gentle handling of the tissues during operative procedures, and appropriate postoperative management will reduce the risk of complications.

Considerations for Mandibular Reconstruction in the Pediatric Patient Following Resection of Malignant Tumors. J Craniofac Surg 2019; 30:e163-e168.

Abstract
We recently achieved favorable results in 3 pediatric patients with mandibular osteosarcomas that were treated at our hospital, including with immediate reconstructive surgery performed after tumor resection. Based on a literature review and practical investigation, we discuss the considerations for mandibular reconstruction after malignant lesions are removed from the mandible in children. Mandibular reconstruction for pediatric patients requires an understanding of the changes in bone and soft-tissue architecture due to growth and development at both the donor and recipient sites. Immediate mandibular reconstruction with a free flap can be considered a reasonable option even for young children who require extensive mandibular surgery. However, the variables affecting decisions about treatment planning vary between the different conditions in individual patients, and moreover, these cases are not common in the pediatric population. Therefore, long-term follow-up treatment and further investigations are required for the optimized diagnosis, treatment, and prognosis of pediatric mandibular malignancies.

Abstract
PURPOSE OF REVIEW To review recent literature on the subject of free tissue transfer options in paediatric head and neck surgery, with a particular emphasis on highlighting the advantages and disadvantages of different reconstructions in the paediatric patient. RECENT FINDINGS Free tissue transfer in paediatric patients is predictable and applicable for a wide range of congenital and acquired defects in the head and neck. The free fibula flap is a mainstay of mandibular reconstruction and allows excellent implant-supported prosthodontic rehabilitation and growth potential at the recipient site with little or no donor site morbidity. Other less commonly explored options include the deep circumflex iliac artery flap, scapula flap and medial femoral condyle flap. The gracilis mucle remains the mainstay for facial reanimation with other options including pectoralis minor, rectus abdominis, extensor digitorum brevis and latissimus dorsi. There are compelling arguments for centralization of services and creative strategies in postoperative rehabilitation (e.g. play therapy). SUMMARY Free flaps in paediatric patients are a viable option and may even have advantages relative to adults because of the absence of atherosclerosis, purported lower risk of vasospasm and proportionally larger vessel size. Transfer earlier in life maximizes functional potential and 'normalizes' treatment.

Abstract
Maxillo-mandibular reconstruction in pediatric patients involves particular functional and cosmetic implications. Attention is required for the craniofacial growth over time, involvement of the permanent dentition, facial symmetry, and donor site morbidity. Our aim is to identify the best reconstructive options for maxilla-mandibular defects in children (<18 years) based on our experience with 25 pediatric patients. We believe that reconstruction has to be performed at the same time as resection in pediatric patients. Local flaps should be reserved for cases of maxillary defects because of malignant neoplasms, which ultimately have poor prognosis. In cases of large mandibular defects, radiotherapy is eventually required. When the condition of the soft tissues is poor (because of previous surgery, etc), free flaps potentially represent the best options. Nevertheless, in patients younger than 5 years old (with no damaged tissues), reconstruction with rib grafts should be performed, and the use of titanium plates should be reserved for very select cases (such as temporary reconstruction in toddlers).

Abstract
Desmoid fibromatosis (DF) is a rare, benign soft tissue neoplasm with high rate of local recurrence. Surgical management of DF in the head and neck can be challenging given the desire to balance the preservation of form and function with the need to minimize local recurrence by achieving complete resection. We present two contrasting cases which highlight the advantages of marginal mandibulectomy over segmental mandibulectomy in children with DF. We favor marginal mandibulectomy even with limited bone stock given the remarkable ability of children to generate new bone.

Abstract
Background Desmoid-type fibromatosis is defined as an intermediate tumor that rarely occurs in the head and neck of children. There is no doubt as to the value of complete surgical excision for desmoid-type fibromatosis. However, in pediatric patients, surgeons may often be concerned about making a wide excision because of the potential for functional morbidity. Some studies have reported a lack of correlation between margin status and recurrence. Therefore, we discussed our findings with a focus on the state of surgical margins. Case presentation We report an unusual case of a 9-month-old Japanese girl who prior to presenting at our hospital underwent debulking surgery twice with chemotherapy for desmoid-type fibromatosis of the tongue at another hospital. We performed a partial glossectomy and simultaneous reconstruction with local flap and achieved microscopic complete resection. We also reviewed available literature of pediatric desmoid-type fibromatosis in the head and neck. Conclusions We described successful treatment for the refractory case of pediatric desmoid-type fibromatosis. The review results showed that some microscopic incomplete resections of tumors in pediatric patients with desmoid-type fibromatosis tended to be acceptable with surgical treatment.

Abstract
BACKGROUND Microvascular reconstruction of the pediatric mandible, particularly when necessitated by severe, congenital hypoplasia, presents a formidable challenge. Complex cases, however, may be simplified by computer-aided design/computer-aided manufacturing (CAD/CAM) assisted surgical planning. This series represents the senior authors' preliminary experiences with CAD/CAM assisted, microvascular reconstruction of the pediatric mandible. METHODS Presented are two patients with hemifacial/bifacial microsomia, both with profound mandibular hypoplasia, who underwent CAD/CAM assisted reconstruction of their mandibles with vascularized fibula flaps. Surgical techniques, CAD/CAM routines employed, complications, and long-term outcomes are reported. RESULTS Successful mandibular reconstructions were achieved in both patients with centralization of their native mandibles and augmentation of deficient mandibular subunits. No long-term complications were observed. CONCLUSIONS CAD/CAM technology can be utilized in pediatric mandibular reconstruction, and is particularly beneficial in cases of profound, congenital hypoplasia requiring extensive, multi-planar, bony reconstructions.

Abstract
Injury is the most common cause of death in pediatric patients, with a large proportion related to head injury. The craniofacial region in children develops rapidly and at an early age, making the area more prominent compared with the remainder of the body, increasing the likelihood of injury. This article reviews the primary management of pediatric soft tissue injuries, including assessment, cleansing, surgical technique, anesthesia, and considerations for special wounds. The secondary management of pediatric facial injury is also discussed, including scar revision, management of scar hypertrophy/keloids, and staged surgical correction.
