Tracheal stenosis or tracheal injury is a distressing condition. The silicone tracheal T-tube presents a substitute for stent of this complicated disease. We have come across a case of tracheal perforation in which tracheoplasty was planned. After traceoplasty silicone tracheal T-tube was placed as a stent. We were not able to connect silicone tracheal T-tube with Bain circuit with ET TUBE No. 8.5, 8, 7.5, 7 connector and it was difficult to ventilate the patient now. We have tried other ET TUBE connector and finally we succeeded to connect ET TUBE No. 5.5 connector with Bain circuit and we were able to ventilate the patient.
