Nine patients with postintubation granulomas of the larynx were evaluated clinically and pathologically in the last seven years.Their ages ranged from 30 to 58 years with an average of 45. There were seven females and two males. They received such operations as thyroidectomy, parotoidectomy etc. under intubation anesthesia.Postintubation granulomas of the larynx developed unilaterally in four patients and bilaterally in five patients. These granulomas were all removed by the use of laryngeal forceps or a laryngeal snare under the modified neuroleptanalgesia except one patient. Extracted granulomas were examined microscopically. Pathological findings of these tissues were charactalized by the development of nonspecific granulation with invasion of small numbers of lymphocytes and eosinophiles as well as edema and small-vascular dilatation in the submucosal layer.We discussed the etiology of postintubation granulomas of the larynx and their process in this paper.
