Aural hematoma is a common pathological condition in veterinary practice with a high incidence rate in dogs. Drainage, corticosteroid injections, and surgical approaches represent the common treatments in these clinical cases. However, surgery leaves visible signs and is usually correlated with recurrence, scars, and deformation of the treated pinna. For this reason, more effective and less invasive methods have been proposed over the years. Platelet-Rich Plasma (PRP) is one of the most promising options due to its pro-regenerative properties and capability to modulate the inflammatory state. The present work reports 12 cases of canine aural hematoma treated with PRP. The PRP treatment was combined with an ultrasound evaluation of the pinna to detect and treat all involved septa. The results show that relatively large volumes (2 mL) of PRP associated with an ultrasound guide are safe and efficacious in the treatment of canine aural hematoma requiring a maximum of two infiltrations, both in acute and chronic conditions. All the patients recovered their normal ear thickness (compared with the controlateral one) without relapses, averaging 38.5 days from their first treatment (10-90 days; SD: 24.7). The key role of PRP combined with a tailored diagnosis process carried out by the veterinarian, which included using an ultrasound system and the proper bandage, suggests that this approach may represent a valid alternative to surgery and corticosteroids.
耳血肿是兽医临床上一种常见的病理状况，在犬类中发病率较高。引流、注射皮质类固醇和手术方法是这些临床病例的常见治疗手段。然而，手术会留下明显痕迹，且通常与复发、瘢痕以及治疗后耳廓变形有关。因此，多年来人们提出了更有效且侵入性更小的方法。富血小板血浆（PRP）因其促进再生的特性和调节炎症状态的能力，是最有前景的选择之一。本研究报告了12例采用PRP治疗的犬耳血肿病例。PRP治疗结合耳廓超声评估，以检测和治疗所有受累间隔。结果表明，在超声引导下，相对大量（2 mL）的PRP对于治疗犬耳血肿是安全有效的，无论是急性还是慢性病例，最多只需两次注射。所有患者的耳朵厚度恢复正常（与对侧相比），且无复发，首次治疗后平均38.5天恢复（10 - 90天；标准差：24.7）。PRP结合兽医进行的定制诊断过程（包括使用超声系统和合适的包扎）的关键作用表明，这种方法可能是手术和皮质类固醇的有效替代方案。
