A 55-year-old male with a fragment of free necrotic thyroid cartilage in the larynx which caused severe dyspnea and hoarseness is reported.
The patient had a history of tele-Cobalt irradiation (7120/8 weeks) for glottic cancer (T₂N₀M₀), which resulted in perichondritis and 4th grade postirradiation lesion (Takeda). Laryngofissure revealed an obstruction of the subglottic space by a free necrotic thyroid cartilage.
All the symptoms disappeared afterremoval of the necrotic mass.
