A 12-Year-Old Child With a Sunken Sternum and Progressive Muscle Weakness: A Case Report.

A 12-year-old girl with facioscapulohumeral muscular dystrophy and severe pectus excavatum presented with progressive dyspnea and restrictive ventilatory impairment. She underwent successful Nuss repair with uneventful recovery. At 6-month follow-up, chest contour and pulmonary function improved, suggesting that surgical correction is feasible and beneficial in FSHD when mechanical restriction predominates.
