Island sternocleidomastoid myocutaneous flap for posterior pharyngeal wall defect repair after anterior cervical spine surgery
INTERNATIONAL WOUND JOURNAL(2022)
Abstract
Injuries and tumours of the cervical spine represent therapeutic challenges to the treating surgeon due to the complex anatomical relationships and biomechanical features. The anterior cervical midline (ACM) and anterior cervical retropharyngeal (ACR) approaches are effective and safe surgical approaches for certain cervical spine lesions, such as cervical spine neoplasms, atlantoaxial subluxation, and certain odontoid fractures. Posterior pharyngeal wall defects (PPWDs) is one of the most frequently encountered surgical morbidities after anterior cervical spine surgery (ACSS). However, limited information has been published concerning effective approaches for PPWD reconstruction after ACSS. The manuscript aimed to describe a novel application of the island sternocleidomastoid myocutaneous flap (ISMF) in the management of PPWDs after ACSS, including surgery with the ACM approach and ACR approach. From April 2015 to November 2019, the clinical data of three patients with PPWDs repaired using the ISMF in Peking university third hospital were retrospectively analysed. The observational indexes are as follows: postoperative survival of the flap, wound healing 2 weeks after surgery, eating and pronunciation function 2 months after surgery. The above indexes of these three cases recovered well. Three patients did not have any persistent PPWD after repair with the ISMF and did not require any further surgical procedures related to the cervical spine.
