Consequences of envenomation from the bite of a brown recluse spider (Loxosceles reclusa) range from mild itching to death. The bite of this spider causes the most severe form of arthropod-induced tissue necrosis. These bites pose several challenges to the clinician in that diagnosis can be difficult, systemic manifestations can occur, and healing can be resistant to conventional measures. Bites to the head and neck-particularly the face-are uncommon, and they have not been widely reported in the otolaryngology literature. As experts in facial soft tissue, otolaryngologists and facial plastic surgeons should be able to recognize and treat these lesions. Because no laboratory test is available to identify the cause of symptoms in these cases, the diagnosis is made clinically. Early intervention can make a significant difference in cosmetic outcome, so a high index of suspicion is warranted. Local wound care includes rest, ice, compression, and elevation of the affected part of the body. Drug therapy with dapsone may limit the severity of the bite and prevent complications. Because some bites cause systemic loxoscelism, clinicians should be familiar with its manifestations. When necrosis occurs despite adequate medical treatment, reconstructive procedures should be delayed until healing is complete. We report 3 cases of brown recluse spider bites to the head. These cases illustrate the broad spectrum of the disease course, and they highlight the therapeutic challenges that these lesions pose.
棕色隐遁蛛(褐皮花蛛)咬伤所致的中毒后果从轻度瘙痒到死亡不等。这种蜘蛛的咬伤会导致节肢动物引起的最严重形式的组织坏死。这些咬伤给临床医生带来了诸多挑战,因为诊断可能困难,会出现全身表现,而且愈合对传统措施有抵抗性。头部和颈部(尤其是面部)的咬伤并不常见,在耳鼻喉科文献中也未得到广泛报道。作为面部软组织方面的专家,耳鼻喉科医生和面部整形外科医生应该能够识别并治疗这些损伤。由于在这些病例中没有实验室检查可用于确定症状的原因,所以诊断是临床做出的。早期干预对美容效果会有显著影响,因此有必要保持高度的怀疑指数。局部伤口护理包括休息、冰敷、加压以及抬高身体的受影响部位。使用氨苯砜进行药物治疗可能会减轻咬伤的严重程度并预防并发症。由于有些咬伤会导致全身性褐皮花蛛中毒,临床医生应该熟悉其表现。当尽管进行了充分的药物治疗仍发生坏疽时,重建手术应推迟到愈合完成之后。我们报告了3例头部被棕色隐遁蛛咬伤的病例。这些病例说明了该病病程的广泛范围,并突出了这些损伤所带来的治疗挑战。
