Masseteric Nerve

Background: In facial reanimation via microneurovascular muscle transfer, dual-nerve reinnervation of the muscle capitalizes on the synergistic effects of spontaneous motion from cross facial nerve grafting (CFNG) and increased excursion from masseteric nerve transfer. Two-stage approaches that delay masseteric nerve transfer until the time of the muscle flap increase spontaneity by maximizing muscle reinnervation from the CFNG. While this 2-stage, dual-nerve approach has been described in adults, we present a series of pediatric patients who underwent this reconstructive technique. Methods: We retrospectively reviewed all pediatric patients who underwent 2-stage, dual-nerve reconstruction with CFNG and ipsilateral masseteric nerve transfers. Procedures were performed between 2004 and 2016 by 2 surgeons at a single centre. Degree of facial paralysis before and after surgical intervention was measured using House-Brackmann scores. Results: Nine patients with a mean age of 8.6 (range: 5-15 years) years at time of surgery underwent 2-stage, dual-nerve reconstruction. Average time between CFNG and transfer of the free gracilis with masseteric nerve transfer was 13.3 (SD 2.4) months. Mean follow-up was 27.3 months (SD 25.7). Patients demonstrated initiation of voluntary movement on paralyzed side by 3.6 months (SD 0.6) on average, with 3 patients demonstrating spontaneous movement at 3 months. Conclusion: The 2-stage, dual innervation technique using CFNG and delayed ipsilateral masseteric nerve transfer with a free gracilis is a promising reconstructive option to maximize spontaneous expression in pediatric patients. Validated, objective scoring systems for excursion are needed before meaningful comparisons can be made to other reconstructive strategies.

Background Given the unsatisfactory outcomes with traditional treatments, there is growing interest in nerve transfers to reestablish ankle dorsiflexion in peroneal nerve palsy. The objective of this work was to perform a systematic review and meta-analysis of the primary literature to assess the effectiveness of nerve transfer surgery in restoring ankle dorsiflexion in patients with peroneal nerve palsy. Methods Methodology was registered with PROSPERO, and PRISMA guidelines were followed. MEDLINE, EMBASE, and the Cochrane Library were systematically searched. English studies investigating outcomes of nerve transfers in peroneal nerve palsy were included. Two reviewers completed screening and extraction. Methodological quality was evaluated with Newcastle-Ottawa Scale. Results Literature search identified 108 unique articles. Following screening, 14 full-text articles were reviewed. Four retrospective case series met inclusion criteria for meta-analysis. Overall, 41 patients underwent nerve transfer for peroneal nerve palsy. The mean age of the patients was 36.1 years, mean time to surgery was 6.3 months, and the mean follow-up period was 19.0 months. Donor nerve was either tibial (n = 36) or superficial peroneal branches/fascicles (n = 5). Recipient nerve was either deep peroneal (n = 24) or tibialis anterior branch (n = 17). Postoperative ankle dorsiflexion strength demonstrated a bimodal distribution with a mean Medical Research Council of 2.1. There were no significant differences in dorsiflexion strength between injury sites (p = 0.491), injury mechanisms (p = 0.125), donor (p = 0.066), or recipient nerves (p = 0.496). There were no significant correlations between dorsiflexion strength and patient age (p = 0.094) or time to surgery (p = 0.493). Conclusions There is variability in dorsiflexion strength following nerve transfer in peroneal nerve palsy, whereby there appear to be responders and non-responders. Further studies are needed to better define appropriate patient selection and the role of nerve transfers in the management of peroneal nerve palsy.

Abstract. Backgrounds: Central obesity, as a pivotal component of metabolic syndrome is associated with numerous co-morbidities. Dietary factors influence central obesity by increased inflammatory status. However, recent studies didn’t evaluate the association between central obesity and dietary inflammation index (DII®) that give score to dietary factors according to their inflammatory potential. In the current systematic review and meta-analysis, we summarized the studies that investigated the association between DII® with central obesity indices in the general populations. Methods: In a systematic search from PubMed, SCOPUS, Web of Sciences and Cochrane electronic databases, we collected relevant studies written in English and published until 30 October 2019. The population of included studies were apparently healthy subjects or individuals with obesity or obesity-related diseases. Observational studies that evaluated the association between DII® and indices of central obesity including WC or WHR were included. Results: Totally thirty-two studies were included; thirty studies were cross-sectional and two were cohort studies with 103071 participants. Meta-analysis of observational studies showed that higher DII® scores were associated with 1.81 cm increase in WC (Pooled weighted mean difference (WMD) = 1.813; CI: 0.785–2.841; p = 0.001). Also, a non-significant increase in the odds of having higher WC (OR = 1.162; CI: 0.95–1.43; p = 0.154) in the highest DII category was also observed. In subgroup analysis, the continent, dietary assessment tool and gender were the heterogeneity sources. Conclusion: The findings proposed that adherence to diets with high DII® scores was associated with increased WC. Further studies with interventional designs are necessary to elucidate the causality inference between DII® and central obesity indices.
