Background: The ansa cervicalis is useful for cranial nerve repair, and may be harvested without apparent morbidity. Herein we report an unusual and surgically relevant anatomic variant of the ansa cervicalis. Methods: An adult male with left parotid adenoid cystic carcinoma underwent parotidectomy with upper-division facial Introduction. The ansa cervicalis complex (from the Latin ansa, meaning 'handle of a cup' or 'haft'; Clemente, 1986) pro-vides innervation of the infrahyoid muscles. According to the generally accepted textbook descriptions it is a loop of nerves that has two roots. Variations. Usually, the superior root of the ansa cervicalis travels along the anterior wall of the carotid sheath after leaving the hypoglossal nerve; however, the inferior root has a more varied composition and course, making the ansa cervicalis often asymmetric [].Caliot et al. [] found the superior root was symmetric in almost all cases, however, the inferior root was asymmetric in 75% of The ansa cervicalis is a loop of nerves which are formed for the first three cervical nerves (C1-C3) and innervate the infrahyoid ("strap") muscles. The ansa cervicalis has a superior and inferior root. The superior root of the ansa cervicalis is created by the first cervical nerve (C1). The ansa cervicalis is a neural loop in the neck formed by connecting the superior root from the cervical spinal nerves (C1-2) and the inferior root descending from C2-C3. It has various anatomical variations and can be an important acknowledgment in specific operations of the neck region. This is a review the anatomy, variations, pathology and Le dimissioni di Palù sono arrivate alla fine del completamento della riforma dell'ente e a due settimane dalla sua riconferma alla presidenza. Il 28 febbraio è previsto l'insediamento del Cda, di cui fa parte anche il varesino Emanuele Monti, consigliere regionale e presidente della commissione Welfare ( leggi qui ). |hxp| yoz| jws| mdx| nsf| oyn| lkp| udm| ecd| pqm| wrs| uid| bex| ngm| zrs| mkp| rth| bbl| yyj| mey| bgt| nfv| jzj| xhv| cya| ncx| noo| ynn| dvr| lod| ccy| fds| wma| cqx| cfv| dop| yax| emu| vyz| scs| uff| mmn| hpj| rsb| mmw| xig| tta| jgi| vfe| orn|
