Traumatic cervicomediastinal emphysema resulting from isolated head trauma is a rare occurrence. Herein, we describe a patient who sustained a closed mastoid injury after being struck with a batted baseball, resulting in acute extensive cervicomediastinal emphysema. Upon further assessment, the patient's aerodigestive tract was determined to have remained intact and unaffected by the injury. The source of soft-tissue air originated from the fractured mastoid. This case demonstrates the protective properties of a well-pneumatized mastoid. Furthermore, we elucidate the pathway by which the mastoid air entered and spread into the surrounding soft tissues of the neck and into the chest.
由单纯头部外伤导致的创伤性颈纵隔气肿是一种罕见的情况。在此，我们描述一名患者，其被击打的棒球击中后发生闭合性乳突损伤，导致急性广泛性颈纵隔气肿。经进一步评估，确定患者的气道消化道保持完整且未受损伤影响。软组织内气体的来源是骨折的乳突。该病例展示了气化良好的乳突的保护特性。此外，我们阐明了乳突气进入并扩散至颈部周围软组织及胸部的途径。
