Trauma or Injury of the Larynx

A large number of factors can produce trauma to the larynx. Classically, the types of trauma are subdivided into (a) mechanical, (b) chemical, and (c) thermal causes. Many traumatic events produce a range of sequelae that are indicated under classifications elsewhere in this manual. Examples include phonogenic mechanical trauma, which may produce edema, inflammation, and granuloma formation. In addition, thermal trauma may produce inflammation initially, and scarring in the long term.
