Because of their life-threatening character perforations of the membranous trachea must be diagnosed as soon as possible. However, the clinical presentation is not obvious in many cases. For the exact detection of the perforations rigid endoscopy is superior to flexible technique. The early surgical repair is recommended for the majority of the cases. Therefore, the transtracheal approach and endoscopical procedures are favorized. Moreover, these methods used routinely in ENT-surgery are also appropriate for lesions of the distal part of the membranous trachea and can be an alternative to the more invasive thoracotomy. Conservative treatment strategies should be limited to selected patients with small lacerations.
