AbstractIntroductionWe report a case of congenital muscular torticollis managed successfully by the endoscopic transaxillary subcutaneous approach without any neck incision.Materials and Surgical TechniqueA 10‐year‐old girl was diagnosed as having right torticollis. After her condition and the necessary procedure were explained to her parents, the patient underwent surgery. The patient was placed in the supine position. A subcutaneous tunnel was made from the anterior axillary fold up to the right sternocleidomastoid muscle. Flow rate and pressure were gradually increased during this process. Then the sternocleidomastoid muscle's sternal and clavicular attachments were dissected and divided.DiscussionScarless surgery is in great demand today. Stealth surgery refers to endoscopic subcutaneous procedures performed without leaving any obvious evidence that an operation has occurred. It involves the excision of benign subcutaneous lesions of the head and neck in children through an incision in the axilla or a hidden incision in the scalp.
