title: Potential airway compromise secondary to impacted Wharton's duct calculus: a noteworthy phenomenon.
abstract: OBJECTIVE
  This case report describes a patient who suffered an acute, severe complication of unilateral submandibular sialolithiasis, the disease process and management of these patients.
  
  
  METHODS
  A 70-year-old woman was under investigation for a recurrent, painful right submandibular swelling and subsequently presented with an acute exacerbation. She exhibited symptoms of acute submandibular sialadenitis, and also reported breathing difficulty and a change in voice quality. Computed tomography imaging showed that this was caused by a submandibular gland duct sialolith, with inflammation extending to the ipsilateral supraglottis. She was treated medically and the stone was removed when the inflammation had stabilised.
  
  
  CONCLUSIONS
  This case highlights the need to thoroughly assess patients with neck swellings, especially when symptoms are atypical, to avoid life-threatening complications.
