Despite being well documented, the exact pathogenesis of OFTP remains unclear. Some studies suggest that it may arise from the early stage of ischemic tracheal wall injury caused by the cuff pressure during intubation. Diagnosis and treatment of OFTP can be facilitated through therapeutic bronchoscopy. In this case report, we describe a patient who presented with dyspnea following repeated intratracheal interventions and was diagnosed with OFTP. The patient was successfully treated with bronchoscopic cryotherapy and was subsequently discharged from the hospital.Keywords: pseudomembrane, OFTP, intratracheal interventions, intubation, dyspnea
