After trauma episodes, subcutaneous emphysema may be caused by a maxillary antral wall fracture that occurs when air pressure is introduced into the fascial planes of the connective tissue. Retropharyngeal emphysema is a severe condition associated with traumatic aerodigestive tract injury and may be associated with life-threatening situations requiring prompt attention and diagnosis in order to prevent serious consequences. Case report: We reported a case of cervicofacial and retropharyngeal emphysema in a 54-year-old patient who stated concerns after blowing his nose several times after a traumatic episode involving orbitozygomatic region. During the patient's hospital course, his airway remained stable, and he was discharged from the hospital 7days later with a prognosis of full recovery, excellent occlusion and facial appearance, and complete resolution of subcutaneous emphysema.
