A normally fit and healthy 17-year-old competitive swimmer presented to the emergency department with a sore throat, odynophagia and dysphonia the day after a routine training session. He was able to eat and drink but the pain kept him awake at night. There was no history of pulmonary disease, trauma or significant exertion during his training.Clinical examination of the neck revealed cutaneous crepitus on palpation, and surgical emphysema involving the subcutaneous tissues of the neck was confirmed on AP/lateral neck X-ray ( Fig. 1). Chest X-ray revealed only a tiny left apical pneumothorax, with no evidence of pneumomediastinum or surgical emphysema of the chest wall.The patient had no stridor or breathing difficulty and his vital signs were normal. Fibre-optic laryngoscopy was unremarkable and he was managed conservatively with analgesia and avoidance of physical exertion. Over the next two days, his symptoms abated, and when he was reviewed in the head and neck clinic, he had complete resolution of the surgical emphysema both clinically and on a repeat AP neck X-ray.The development of cervical emphysema has multiple recognized associations (Table 1).
