- Anatomical Study of the Innervation of the Masseter Muscle and Its Correlation with Myofascial Trigger Points(2020) PINHEIRO, Roberto Procopio; GAUBEUR, Matheus Aquesta; ITEZEROTE, Ana Maria; SALEH, Samir Omar; HOJAIJ, Flavio; ANDRADE, Mauro; JACOMO, Alfredo Luiz; AKAMATSU, Flavia EmiBackground and Purpose: Myofascial pain syndrome (MPS) is widely prevalent in the general population; some reports estimate its prevalence ranges from 9 to 85%. Among the different locations where MPS may arise, pain related to the masseter muscle is referred as masticatory myofascial pain. MPS is characterized by myofascial trigger points (MTPs), which represent tender anatomical areas of a muscle where painful symptoms are elicited whenever stimulated. Previous publications have found MTPs to coincide with neuromuscular junctions at the motor end plate, at the innervation zone (IZ). Our study aimed to describe the innervation of the masseter muscle and relate it to clinically described myofascial trigger points (MTPs). Materials and Methods: We mapped the nerve fiber distribution into the masseter muscles from 16 cadavers by anatomical dissection. We divided the muscle into six regions, three superior (I-III) and three inferior (IV-VI), and classified the nerve's branches distribution according to these predetermined areas. Statistical analyses was made by Poisson distribution and logarithm link function followed by Bonferroni multiple comparisons (P<0.05). Results: All six areas received branches from the masseteric nerve. Areas I and II (upper posterior and upper intermediate, respectively) had a significant higher number of nerve entries as compared to the remaining areas. Conclusion: The penetration areas of the masseteric nerve have been established and MTPs are found in the innervation zones, clinicians should focus initially on the regions of the penetration points, for diagnostics and therapeutic measures, such as injections, dry needling and soft tissue interventions. Anatomical study of nerve supply to the masseter muscle can provide useful additional knowledge to further understanding masticatory myofascial pain and to direct therapeutic interventions and diagnostic studies of temporomandibular junction dysfunction.

article 3 Citação(ões) na Scopus Anatomy of the Lymphatic Drainage of the Upper Limb and Breast and its Role in Lymphedema Prevention after Breast Cancer Treatment(2016) CUADRADO, G. A.; ANDRADE, M. F. C.; AKAMATSU, F. E.; JACOMO, A. L.The surgical treatment of breast cancer has been enhanced throughout the years in order to offer oncologically safer and more effective results with lower esthetic impact and fewer sequelae. The lymphedema of the upper limb is still an iatrogenic result of great incidence and morbidity after this treatment. A possible existence of independent breast and upper limb lymphatic pathways has become the issue of many researchers willing to minimize its occurrence. This review aims to compare the lymphatic pathways in the axilla described by traditional anatomy books and recently published articles about Axillary Reverse Mapping (ARM). With this purpose, a comparative table was made with the descriptions found in books and articles, a statistic table of the data collected, a flowchart of anastomoses among nodes and an analytical drawing of the most statistically mentioned drained areas. It was observed that there is great variability in the descriptions of drainage and anastomoses among the lymph nodes in the references used, so there should be a consensus of a universal description which also assembles possible anatomical variations. Furthermore, the findings brought about by recent studies show possible anastomoses among pathways and lymph nodes, however they have not been taken into consideration when ARM was initially proposed. Therefore, the axillary resection with the preservation of the posterior and lateral axillary lymph nodes is theoretically possible to avoid lymphedema of the upper limb, but the development of an updated universal description that involves all possible anatomical variations will provide a safer and more effective treatment.- Anatomical Substract of the Temporal Muscle Myofascial Trigger Points in Fresh Cadavers(2022) GARRIDO, Luis C.

conferenceObject PROGNOSTIC IMPACT OF THE LYMPH NODE METASTATIC RATIO IN 5-YEAR SURVIVAL OF PATIENTS WITH RECTAL CANCER NOT SUBMITTED TO PREOPERATIVE CHEMORADIATION.(2013) MARTINEZ, C. Real; JACOMO, A.; AKAMATSU, F.; PEREIRA, J.; NONOSE, R.; SATO, D.; RODRIGUES, M.- Syntopy of vagus nerve in the carotid sheath: A dissectional study of 50 cadavers(2019) HOJAIJ, Flavio; REBELO, Gabriela; AKAMATSU, Flavia; ANDRADE, Mauro; CAMARGO, Cristina; CERNEA, Claudio; JACOMO, AlfredoBackground Vagus nerve anatomical position inside the carotid sheath is not clear in the literature. Nevertheless, monitoring laryngeal nerves during thyroid surgeries may damage big vessels in the carotid sheath (jugular vein; carotid artery). This gap led to an unprecedent cross sectional study of vagus syntopy using the carotid artery as anatomical mark. Methods Fifty cadavers less than 24 hours postmortem were studied. The vagus nerve was spotted, reproducing the patterns performed in thyroidectomies. Results On the right side, vagus nerve was posterior to the common carotid artery in 64% of the cases. On the left side, it was anterior, in 68% of the dissections. Comparing both sides, there was no symmetry in this syntopy. No influence of ethnic or anthropometric characteristics was observed. Conclusion The vagus nerve is more frequently posterior to the common carotid artery on the right side and, anterior, on the left side. Level of Evidence 4

- Ensino da anatomia: dissecção em associação com a tecnologia no curso de Medicina(2023) VIEIRA, Joaquim Edson; AKAMATSU, Flávia Emi; JÁCOMO, Alfredo LuizAbstract: Introduction: A 2010 study pointed out the future needs of medical education, with integrated contents and practices, fostered by virtual educational technology and by prioritizing competence, not time. Anatomy, indistinguishable from other fundamentals of medicine, faces restrictions on cadaver dissection. Objective: Essay on the teaching of anatomy in clinical contexts and the use of technologies Method: The “pubmed” platform of the National Library of Medicine and descriptors ((anatomy[MeSH Terms]) AND (method, teaching[MeSH Terms])) AND (surgery[MeSH Terms]) were used. Result: There are indications of 316 articles in the period 2000-2022 (June 2022). The main question about the teaching of Anatomy is the replacement of the dissection technique and, consequently, the use of the cadaver. Studies suggest maintaining the use of dissection, prosection and greater use of digital and model means. Conclusion: Cadaveric material should be secured with greater use of prosection and dissection being directed or elective. Virtual reality and permanent material must be assimilated as instrumental and supervised by qualified anatomists and enriched by interpretation and clinical applicability.
- Anatomical Bases of the Temporal Muscle Trigger Points(2024) GARRIDO, Luis Carlos Fernandez; SIMONETTI, Giulianna; SALEH, Samir Omar; HOJAIJ, Flavio; ANDRADE, Mauro; JACOMO, Alfredo Luiz; AKAMATSU, Flavia EmiBackground and Purpose. Myofascial pain syndrome (MPS) is a chronic or acute form of musculoskeletal pain that affects nearly three-quarters of the world's population. It is characterized by muscle pain and stiffness, with palpable nodules and hyperirritability areas called myofascial trigger points (MTPs). The temporal muscle is frequently involved in MPS, and four MTPs in the temporal muscle have been described in the literature, but no anatomical description of the MTPs has been reported. The present study described the entry points of deep temporal nerves in the temporal muscle belly and related these points to the MTPs described in the literature. Method. Temporal muscles of 14 adult cadavers were studied. The muscle bellies were divided into six areas, three superior (1.2 and 3) and three inferior areas (4, 5, and 6) lower, according to a Cartesian plane to analyze and describe the entry points of the branches of the deep temporal nerves into the muscle. The branching distribution was analyzed using Poisson log-linear tests with Bonferroni post hoc tests for comparison between groups (sextants) (p<0.05). Results. Deep temporal nerve entry points were found in the temporal muscle in all areas. Most of the branches were observed in areas 2 and 5, which coincide with the muscle fibers responsible for mandible elevation and related to the previously described MTPs. Fewer branches were found in areas 1 and 6, where contraction produces mandible retraction. Conclusion. There is an anatomical correlation between the branching pattern of the deep temporal nerve and temporal muscle trigger points. Adequate knowledge of the innervation of the temporal muscle may help elucidate the pathophysiology of myofascial syndromes and provide a rational basis for interventional or conservative approaches and help surgeons avoid iatrogenic lesions to the deep temporal nerve lesion.
