  • Secondary to tongue biting

Clinical Features

  • Examine for other injuries, missing teeth, embedded foreign bodies

Differential Diagnosis

Tongue diagnoses


  • Do not need primary repair unless >1 cm in length, widely gaping, involving tip / anterior split tongue, or large hemorrhage
    • Use absorbable sutures, chromic gut or vicryl but not fast absorbing
    • Tie 4-5 knots but approximate loosely to allow for swelling
    • Anesthesia of the anterior 2/3 of the tongue is obtained through an inferior alveolar nerve block
    • Chlorhexidine mouth wash to prevent infection
