Popis: Introduction: Anhydrous Ammonia (AA) is a caustic compound commonly used in the industry that can cause burns, even with brief contact. As with other alkali burns, the early washing to remove the AA from burnt areas is crucial to limit tissue damage. The concentration of toxic agent and duration of its contact determine the degree of skin and mucosa destruction. A tanker truck carrying AA (NH3) fell off a highway, and released a dense cloud of AA gas. Fifty-four people inhaled the gas and after ninety days, three people were still experiencing hoarseness and were examined. Case Report: We assessed three patients with laryngeal sequelae due to AA inhalation burn. We found a case of hyperemia and edema, one case of granuloma of the posterior third portion of the left vocal cord, and one case of vocal cord adhesion. Necropsy findings are commented both macroscopically and microscopically. The sequelae and the best treatments for them are discussed herein.
