Abstract
Neck emphysema after tonsillectomy surgery is very rare. We present a case documenting the conservative management of a post-tonsillectomy neck swelling, accompanied by crepitus. Computed tomography revealed a large air density at the region of the right masticator space and the masseter muscle, proximal to other deep neck spaces and muscles. Further investigations of her associated symptoms resulted in an additional diagnosis of systemic lupus erythematosus. We have also explored the signs and symptoms associated with such cases, along with a discussion of the literature published on surgical emphysema post-tonsillectomy.
