Introduction: There are numerous differential diagnoses of benign lesions of the larynx. If they protrude into the laryngeal lumen they can cause hoarseness, cough, dyspnoea and stridor.

A rare differential diagnosis of a benign lesion of the larynx is the prolapse of the laryngeal ventricle. Due to chronic inflammatory changes with consecutive proliferation, varying degrees of metaplasia, edema, glandular atrophy and fatty infiltration of the mucosa and submucosa there is an increase in mass of the periventricular tissue, the mucosa of the ventricle is pushed out of the ventricle and into the airway. Therefore the term prolapse of the ventricle is misleading, as it is not a prolapse in the sense of a falling down of an organ or part.

Case report: A 38 yo female patient presented to our department for phoniatrics with a 10 days history of hoarseness. She is working as a teacher with a history of chronic voice abuse. Assuming acute laryngitis, she was treated with a course of antibiotics by her local ENT practitioner. The hoarseness didn’t improve. Stroboscopy showed a bilateral protrusion between the true and false vocal folds. No restriction of movement was found, stroboscoby showed a normal mucosal wave pattern with regular amplitudes and slight asynchronicity. Due to her altered voice, the protrusions were excised. Histopathology showed respiratory mucosa with seromucinous glands and fatty infiltration.

Conclusion: Protrusion of the laryngeal ventricle is a rare differential diagnosis of a benign lesion of the larynx. Microsurgical excision and histopathological examination is to be considered in cases of reduced voice quality or for the exclusion of malignancy.
