CHONDRONECROSIS


This is a rare complication that usually occurs following
radiation therapy to the larynx. It can occur a few months to
many years after radiation.

Usually, a minor traumatic event
sets off the process, although it has been known to start
spontaneously. The patient complains of poorly controlled
pain, dysphagia, and aspiration.

Clinical examination may be unrewarding,
although rarely a discharging sinus may be
present. Usually, diffuse laryngeal oedema is all that
is seen. In severe cases, endoscopic examination may reveal
necrotic cartilage sequestrating into the laryngopharynx.

A high index of suspicion should be maintained to
arrive at the diagnosis.

A CT scan will reveal evidence of
chondronecrosis.
