After bullectomy, surrounding healthy lung tissue expands, and chest mechanics improve by virtue of the remodeling of the thorax and diaphragm. Symptomatic improvement (dyspnea, exercise capacity, need of oxygen) and functional improvement occur. [9, 10, 11, 12, 13, 14, 15, 16]

The greatest benefit is seen in patients with large bullae accompanied by crowding of adjacent structures, upper-lobe predominance, and minimal underlying emphysema. [17]

Preoperative bulla size is the most important determinant of improvement in ventilatory capacity after bullectomy. [18]
