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.

Massive Self-Induced Subcutaneous Cervicofacial, Pneumomediastinum, and Pneumopericardium Emphysema Sequelae to a Nondisplaced Maxillary Wall Fracture: A Case Report and Literature Review.

Iatrogenic cervicofacial subcutaneous emphysema is a well-reported entity in the field of dentistry and oral and maxillofacial surgery, especially with the use of air-driven headpieces. Cervicofacial subcutaneous emphysema sequelae after maxillofacial trauma, however, has been reported less and the self-induced variant is even rarer. We report a case of massive cervicofacial subcutaneous emphysema, pneumomediastinum, and pneumopericardium in a healthy 16-year-old boy after blunt trauma to the face, which caused a nondisplaced anterior maxillary wall fracture.
