Five cases are presented with a strained voice quality due to a unique underlying cause: thyroid cartilage cysts. Laryngoscopy and radiological images show antero-medial displacement of both vestibular and vocal fold(s). Swelling in the ala of the thyroid cartilage results in a pear-shaped lumen. These cysts were marsupialized with CO2 laser, fluid emerged, and histological biopsies confirmed cartilaginous cysts. Postoperatively, all cases report largely reduced or completely resolved vocal complaints, with a consistent follow-up of 2 years. Together with previous publications, an overview of 17 cases is presented, to enhance awareness that thyroid cartilage cysts can cause a strained voice quality. Laryngoscope, 130:E628-E631, 2020.
