Non-Specific Laryngeal Granuloma with Sinobronchial Syndrome

Abstract

Laryngeal granuloma can be classified into specific granuloma and non-specific granuloma. The latter is relatively rare and recurs frequently. The causes of non-specific laryngeal granuloma are divided into intubation, contact and idiopathic types. We reported two cases of laryngeal granuloma with sinobronchial syndrome that were cured by laryngeal microsurgery using a CO₂ laser. The mechanism of granuloma formation is considered that the vocal cord membrane was damaged by strong pressure during consecutive coughing and chronic stimulation by post nasal drip and sputum in the patients with sinobronchial syndrome. We concluded that sinobronchial syndrome is one of causes of laryngeal granuloma formation.
