Event Description

This report is being filed after the review of the following journal article: buckley m., et al (2021) double mandibular osteotomy for access to high-carotid pathology, ann vasc surg volume 70: 202¿212 (usa).This retrospective study aims to report our outcomes utilizing the dmo technique developed in our academic medical center for exposure of high-carotid artery pathology including carotid stenosis, carotid body tumors, and carotid aneurysms.From 2011 to 2019, fifteen patients (10 women and 5 men) with age range of 27-76 years with a mean of 60.7 years underwent 16 procedures utilizing dmo for exposure and repair of skull-based carotid artery lesions for treatment of carotid atherosclerotic disease, carotid body tumors, and extracranial carotid aneurysms at the university of tennessee medical center in knoxville were evaluated.The planned sub condylar osteotomy (proximal) superior to the lingula and the vertical osteotomy (distal) anterior to the mental foramen was delineated.A synthes (depuy synthes, west chester, pa) 2.0 mm reconstruction bone plate was then adapted and secured to span the osteotomies.The plate was removed after placement in preparation for the osteotomies.A panoramic radiograph was obtained before discharge from the hospital, and repeat panoramic radiographs were obtained at 3 months, 6 months, 12 months, and 24 months postoperatively to investigate the healing of the osteotomy sites and stability of bone plates.The following complications were reported: patient no.1 developed dysphagia requiring enteral feeding via peg tube due to sacrifice of cranial nerve ix and x.Attributed to the dmo procedure itself.Patient no.9 developed dysphagia requiring enteral feeding via peg tube.Patient no.10 developed dysphagia requiring enteral feeding via peg tube / bilateral postoperative strokes with recovery.Patient no.11 developed dysphagia requiring enteral feeding via peg tube.Patient no.13 developed dysphagia requiring enteral feeding via peg tube.Patient 7 developed chronic osteomyelitis of the mandibular segment requiring operative debridement and intravenous antibiotic therapy with subsequent distal segment hardware removal.This was the only patient to demonstrate oral exposure of an exposed screw thread in the distal segment that required secondary removal after earlier bone plate removal in this segment.Attributed to the dmo procedure itself.One patient with contralateral carotid occlusion suffered a watershed cortical infarct in the contralateral hemisphere due to inability to place a carotid shunt.This patient ultimately recovered with no chronic neurologic sequelae.Patient no.5 had significant postoperative malocclusion.Attributed to the dmo procedure itself.Patient no.8 had significant postoperative malocclusion.Attributed to the dmo procedure itself.This report is for an unknown synthes 2.0 mm reconstruction bone plate.This report is for (1)unk - screws: trauma.This report is 6 of 13 for (b)(4).
