Abstract:

【Abstract】 Objective: To improve the routine operation for treating congenital torticollis on the basis of characteristics of cervical fascia. Methods: 12 embalmed adult cadavers were used in this study. Anatomic relationship of the platysma muscle and the superficial layer of cervical fascia(envelope fascia) were dissected and observed. The envelope fascia were cut about 3cm longitudinally 1.5cm above the clavicle and 0.5cm medially to the medial boundary of the sternocleidomastoid muscle, and then, the lateral border of sternocleidomastoid were divided from the deeper of the posterior sheath of the muscle, for the exposure and observation of the deep layer of cervical fascia and carotid sheath. Results: The superficial layer of cervical fascia was intact and compact, which enveloped the sternocleidomastoid thoroughly and can be dissected from platysma muscle easily at the anterior part of the neck. At the middle and inferior part of the neck, the hind fascia sheath of the sternocleidomastoid can be separated from the carotid sheath easily. Conclusions: According to the anatomic features of cervical fascia, it's possible to improve the operation for treating congenital torticollis.
