Treatment of pectus excavatum.
(a)
When no cardiac or pulmonary disturbance or pain is present, patients and families may choose observation only, and live with the thoracic defect, returning for care if the condition worsens or physiologic symptoms develop.
(b)
Surgical repair of defect, when chosen, is best deferred until age 15-years-old or older, because there is a higher incidence of recurrence in children who are repaired younger.
