BackgroundTracheomalacia may be caused by long-standing compression of retrosternal goitre because of destruction of support of tracheal cartilages. Life-threatening airway collapses may occur after surgical removal of goitre. However, available literature on management methods of tracheomalacia is sparse. Our study highlights prolonged endotracheal intubation as a feasible treatment method.MethodsThis retrospective study analysed 106 thyroidectomies for retrosternal goitre performed between 1994 and 2019. We recorded each patient's clinical profile. Severe tracheomalacia was confirmed through the following: soft and floppy trachea on intra-operative palpation and the collapse of cross-sectional tracheal area measured in computed tomography (CT) images by >80%. We assessed the extent of airway stenosis of these cases. All severe cases were treated by prolonged endotracheal intubation.ResultsSurgical treatment was successfully performed in all 106 retrosternal goitre patients with no mortality. Seventeen severe tracheomalacia cases were confirmed. The extent of airway stenosis was assessed: the minimal tracheal diameter of compressed trachea was 0.2-0.4 [mean 0.31, standard deviation (SD) 0.06] cm, and the narrow tracheal length was 4-6.7 (mean 5.1, SD 0.6) cm. These patients underwent endotracheal intubation for 17-47 h after surgery. All patients were transferred to the general ward after extubation and successfully discharged. There were no cases of tracheal stenosis on follow-up.ConclusionsTracheomalacia is a rare but serious complication of retrosternal goitre surgery. Based on our experience, prolonged endotracheal intubation is a feasible treatment for tracheomalacia after retrosternal goitre surgery.
