Perilymph fistulae are difficult to diagnose because they present with a wide variety of signs and symptoms, they are associated with many etiologies, and they often mimic other conditions. In this article, we describe a case of perilymph fistula that featured one of its more rare causes: acoustic trauma--specifically, damage from a loud blast from the siren of a fire engine. We also review the literature and discuss the difficulties of diagnosis and treatment and the possible mechanisms by which acoustic trauma and other etiologies cause perilymph fistulae.
外淋巴瘘很难诊断，因为其表现出多种多样的体征和症状，与多种病因相关，且常与其他病症相似。在本文中，我们描述了一例外淋巴瘘病例，其病因较为罕见：声创伤——具体而言，是消防车警报器的巨响造成的损伤。我们还回顾了文献，讨论了诊断和治疗的难点以及声创伤和其他病因导致外淋巴瘘的可能机制。
