Background: Endotracheal intubation can cause focal ischemia, damage or edema to the laryngeal mucosa, and may be followed by serious complications such as vocal cord paralysis, ulcers, and granulation tissue formation. Laryngeal granuloma is rare but also a significant late complication of endotracheal intubation, and anesthesiologists should be concerned about it.
Case: We experienced four cases of laryngeal granuloma that developed after two-jaw surgery January 2017–December 2018 in our hospital and would like to report these cases with brief review of literature.
Conclusions: There are frequent movements on the head and neck in maxillofacial surgery and the nasotracheal intubation should be prolonged after bimaxillary osteotomy surgery because of post-operative airway problems. This may be why two-jaw surgery may have higher occurrence of laryngeal granuloma than others.
Key Words : Endotracheal intubation; Laryngeal granuloma; Maxillofacial surgery.
