[Diagnosis difficulties of a traumatic lesions of the upper airways about one case].

Cervical region traumas can involve various structures and their assessment is difficult. Vascular and aero digestive lesions (ENT and esophageal sphere) are at the forefront of the lesion assessment. Lesions of the ENT sphere are generally expressed by respiratory signs of varying intensity. They are rarely silent. The authors report a case of cervical wound with vascular lesion in the foreground and large laryngeal tracheal lesions (a section of the first and second tracheal rings, multiple cuts in thyroid cartilage with section of the anterior part of the cricoid cartilage) without clinical expression, discovered during surgical exploration. The circumstances of occurrence, the invasive agents and the management are discussed.
