Osteoblastoma of the thyroid cartilage treated with voice preserving laryngeal framework resection.

Osteoblastoma is a slow-growing, locally destructive benign bone neoplasm, rarely occurring in the laryngeal cartilage. We present the case of a professional voice user diagnosed with laryngeal osteoblastoma after microdirect laryngoscopy and endoscopic biopsy. Her treatment required a unique operation, with elements of partial laryngectomy and maintenance of vital endolaryngeal soft tissues, in order to optimize vocal outcome.
