Abstract
Trauma or lesion resection often causes complex wounds with deep soft tissue defects in extremities. Simply covering with a skin flap will leave a deep dead space resulting in infection, non-healing wounds, and poor long-term outcomes. Thus, effectively reconstructing complex wounds with dead space leaves a clinical challenge. This manuscript presents our experience using chimeric medial sural artery perforator (cMSAP) flap, to reconstruct complex soft tissue defects of the extremities, thereby exploring broader analysis and indications for future reference. Between March 2016 and May 11, 2022, patients (8 males and 3 females) with a mean age of 41 years (range from 26 to 55 years) underwent reconstructive surgery with the cMSAP flap. The cMSAP flap consists of an MSAP skin paddle and a medial sural muscle paddle. The size of the MSAP skin paddle ranged between 9 × 5 cm and 20 × 6 cm, and the size of the medial sural muscle paddle ranged between 2 × 2 cm and 14 × 4 cm. Primary closure of the donor site was achieved in all cases. Of the 11 patients, the cMSAP flap survived in 10 cases. The vascular compromise occurred in one special case and was treated with surgical procedures. The mean follow-up duration was 16.5 months (range of 5-25 months). Most patients present satisfactory cosmetic and functional results. The free cMSAP flap is a good option for reconstructing complex soft tissue defects with deep dead space in extremities. The skin flap can cover the skin defect, and the muscle flap can fill the dead space against infection. In addition, three types of cMSAP flaps can be used in a broader range of complex wounds. This procedure can achieve an individualised and three-dimensional reconstruction of the defects and minimise the donor site morbidities.

Abstract
PURPOSE To evaluate a novel method and computed tomography angiography (CTA) for locating anterolateral thigh flap (ALTF) perforators to design individualized ALTFs to reconstruct maxillofacial soft tissue defects. STUDY DESIGN This study comprised a group of 36 patients (CTA group) with malignant oral and maxillofacial tumors who underwent CTA and who received individualized ALTFs and a group of 28 patients (control group) with the same condition but without preoperative CTA examination and with nonindividualized ALTFs. ALTFs in the CTA group were designed and harvested using the locating device and CTA, whereas ALTFs in the control group were designed and harvested according to each surgeon's experience. RESULTS Fifty perforators were located and 36 ALTFs harvested in the CTA group. In the control group, 34 perforators were located and 28 ALTFs harvested. Less time was required to locate the perforators in the CTA group. Moreover, the CTA group had a higher flap survival rate and better patient satisfaction regarding the postoperative aesthetics and phonetic and swallowing functions. CONCLUSIONS The results suggest that CTA and the locating device can be used to accurately locate ALTF perforators and that this method aids in the design and harvesting of individualized ALTFs to achieve good functional and aesthetic outcomes.

Abstract
Background: During repair of oral and maxillofacial soft tissue defects, organ function is largely related to the amount of thickness of the flap. However, there are few studies on the influencing factors of the thickness of the flap. In this retrospective study, we aim to explore the correlation between body mass index (BMI) and anterolateral thigh (ALT) flap thickness by computed tomography (CT) and ultrasound and provide guidance for evaluating the ALT flap thickness before surgery. Methods: We selected three points A, B, and C on ALT flap and two skilled clinicians measured the thickness of these points. Age and gender as covariates and evaluated by the Chi-square analysis. Inter-group differences between the two BMI groups were examined by the student t test. Intra-group differences within each BMI group were tested by ANOVA. Linear regression analysis was performed to examine the relationship between BMI and ALT flap thickness. Results: One hundred sixty patients measured by CT were included in this study, and the ALT flap thickness measured by CT were 8.96 mm and 11.00 mm (P < 0.0001, t test) at point B in groups with BMI<24.0 and BMI≥24.0, respectively. The thicknesses at points A, B, and C were significantly correlated with the BMI (P < 0.001, correlation analysis, r = 0.462, 0.372, and 0.349 at the points A, B, and C, retrospectively, Pearson test). Conclusion: There was a significant correlation between the ALT flap thickness and BMI. A higher BMI was correlated with a thicker ALT flap.

Abstract
PURPOSE OF REVIEW Options for segmental mandibular reconstruction in patients poorly suited to undergo fibula free flap (FFF). RECENT FINDINGS Although FFF is the current 'gold standard' for segmental mandibular reconstruction, other reconstructive options must be considered when FFF is contraindicated or disfavoured and/or patient frailty precludes a lengthy anaesthetic. In addition to various nonvascularized and soft tissue only reconstructions, excellent osseous free flap alternatives for functional segmental mandibular reconstruction may be employed. The subscapular system free flaps (SSSFF) may be ideal in frail and/or elderly patients, as SSSFF allows for early mobility and does not alter gait. In extensive and/or symphyseal defects, functional mandibular reconstruction in lieu of a free flap is extremely limited. Pedicled segmental mandibular reconstructions remain reasonable options, but limited contemporary literature highlights unpredictable bone graft perfusion and poor long-term functional outcomes. SUMMARY There are several excellent free flap alternatives to FFF in segmental mandibular reconstruction, assuming adequate cervical recipient vessels are present. On the basis of the current literature, the optimal mandibular reconstruction for the medically frail, elderly and/or patients with extreme vessel-depleted necks is limited and debatable. In qualifying (i.e. limited, lateral) defects, soft tissue only reconstructions should be strongly considered when osseous free flaps are unavailable.

Abstract
OBJECTIVE Ablations of locally advanced or recurrent head and neck cancer commonly result in large composite orofacial defects. Chimeric flaps represent a unique surgical option for these defects, as they provide diverse tissue types from a single donor site. The purpose of the study was to consolidate the literature on chimeric flaps with regard to postoperative complication rates to help inform surgical decision making. DATA SOURCES The librarian created search strategies with a combination of keywords and controlled vocabulary in Ovid Medline (1946), Embase (1947), Scopus (1823), Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, and Clinicaltrails.gov (1997). REVIEW METHODS Candidate articles were independently reviewed by 2 authors familiar with the subject material, and inclusion/exclusion criteria were uniformly applied for article selection. Articles were considered eligible if they included patients who received a single chimeric flap for reconstruction of head and neck defects and if they provided data on complication rates. RESULTS A total of 521 chimeric flaps were included in the study. The major complication rate was 22.6%, while the minor complication rate was 14.0%. There were 7 flap deaths noted in the series. Median operative time and harvest time were 15.0 and 2.5 hours, respectively. CONCLUSION Chimeric flaps represent a viable option for reconstruction of complex head and neck defects and have complication rates similar to those of double free flaps and single free flaps with locoregional flap while only modestly increasing total operative time.

Abstract
Background An oncologic tumor resection of the scalp can result in complex wounds that result in challenging scalp reconstructions. This study aimed to evaluate the outcomes of microvascular-based scalp reconstructions (MSR) in oncologic patients and to propose an algorithmic treatment approach. Methods Within a 5-year period, 38 patients having undergone 41 MSR (15 anterolateral thigh (ALT), 15 gracilis muscle (GM), and 11 latissimus dorsi muscle (LDM) flaps) after extensive scalp tumor resections fulfilled inclusion criteria for this study. Results Malignant skin disease included superficial and/or deep infiltration of the calvarium in 26 and combined intracranial infiltration in 12 patients. In case of bone replacement (24 patients), MSR was done concomitant, otherwise MSR was performed after pathological confirmation of tumor-free margins. LDM flaps were used in cases with defect sizes of 400 to 1250cm 2 , whereas ALT- and GM flaps were chosen for defects ranging from 40 to 350cm 2 . The average length of the pedicle was comparable in ALT- and LDM flaps and longer than in GM flaps. Total flap loss with need for revision surgery and minor donor site morbidity occurred in four and three patients, respectively. Conclusion Microsurgical reconstruction of moderate-to-extensive scalp defects remains a reliable method with overall low risks and satisfactory aesthetic results, while, according to our experience, muscle flaps show the best functional and aesthetic results. However, in cases of central scalp defects and in situations when a long vascular pedicle of the flap is important, the ALT flap seems to be the best solution.
