RESUMEN
BACKGROUND: A heavy burden of cranio-maxillofacial complications may be encountered in corona virus disease-2019 patients due to the associated coagulopathy and inflammatory consequences of the disease. This study aims to describe clinical and radiographic features of these complications in 256 patients who developed 1 or more of the following complications: cavernous sinus thrombosis, osteomyelitis or necrosis of the jaws. METHODS: Clinical assessment of cranial nerve function and general clinical assessment were performed. Imaging techniques used were multi-slice computed tomography, magnetic resonance imaging, and MRI with contrast enhancement. RESULTS: Thromboembolism of brain and facial blood vessels were associated with inflammation and necrosis. Multi-slice computed tomography/MR angiography showed thrombotic occlusions of the internal carotid artery in the area of the cavernous sinus, and in the ophthalmic veins. Cavernous sinus thrombosis was attributed to coagulopathy and, inflammation of the paranasal sinuses, especially sphenoiditis. A noticeable increase in the size of the cavernous sinus was detected. Compression of the cranial nerves in the cavernous sinus (CS) region causes dysfunction and pathology in the corresponding regions.
