Caption

Axial unenhanced end-expiratory CT images of the trachea in 54-year-old man (a) before and (b) 6 months after bariatric surgery with 46-kg weight loss (body mass index decrease, 28.0%). Tracheal cross-sectional area increased from 241 mm2 before surgery to 339 mm2 after. Tracheal shape changed from moderate anterior bowing of the posterior tracheal membrane (grade 3) before surgery to flattening of the posterior tracheal membrane (grade 1) after surgery.
