An unusual supplemental vehicle restraint-induced injury: Report of case and review of literature

Significant post-traumatic hemorrhage from a submandibular gland injury: a case report

“…Additionally, as seen with this patient, SMG trauma can result in delayed airway compromise. If intubation is withheld, providers should be aware that the progression of airway swelling has been documented in cases up to 36 hours after the event [5]. If intubation is withheld, it should be noted that an expanding hematoma across the cricoid membrane could quickly develop, which is a relative contraindication to cricothyrotomy and potentially detrimental to the patient [6].…”

Acute Mandibular Swelling Following Blunt Trauma

“…Salivary gland injury is uncommon, and injury to the submandibular gland much less common than injury to the parotid gland due to the protection of the former by the mandible [1,5]. Case reports of submandibular trauma in adults have involved a fishbone [6], motor vehicle accidents [3,[7][8][9], and gunshot wounds [2,10]. Blunt trauma causing submandibular gland injury, also following a fall, has been described in an adult [11].…”

“…The differential diagnosis of an acute mass with radiological evidence of a collection in close proximity to the submandibular gland after trauma includes a hematoma [3,7,8], salivary gland disruption with sialocoele or mucocoele formation [8,39], abscess, and exacerbation of an underlying lesion such as a lymphatic or vascular malformation [35]. Developing abscesses in salivary glands form as enhancing collections on CT with contrast [36,40] or MRI, with a diffuse T2 hyperintense signal.…”

Isolated Submandibular Gland Injury in the Setting of Blunt Trauma

“…Appropriate follow-up is important to look for late complications such as a sialocele, salivary fistula, sialadenitis, and gland fibrosis. 4 The most commonly reported complication of submandibular trauma is a fistula. [1][2][3][4] The treatment of this is now thought to be best handled conservatively in the same manner that noncomplicated submandibular injury is treated.…”
