COVID-Associated Avascular Necrosis of the Maxilla-A Rare, New Side Effect of COVID-19.

PURPOSE: The purpose of this article is to present an interesting, rare case of a patient who experienced avascular necrosis of the maxilla associated with COVID-19 infection. METHODS AND RESULTS: Our team retrospectively evaluated this patient's chart after completion of surgical management. The patient is a 72-year-old male who presented to the University of Texas Health Science Center at Houston for surgical management of his infarcted maxilla, which developed as a sequela of infection with COVID-19. A literature review was completed using PubMed. Twenty-five articles are reviewed and discussed. CONCLUSIONS: Infection with COVID-19 confers a hypercoagulable state in patients, leading to various complications in the head and neck region. In our case report, we present a patient who developed avascular necrosis of the maxilla secondary to infection with COVID-19. Thromboembolic prophylaxis is imperative in COVID-19 patients due to the high rate of potential systemic complications.
