This manuscript reports seven horses suffering from mycotic rhinitis and paranasal sinusitis and describes the clinical signs, treatments and outcomes. Mycotic plaques were observed in the nasal portion of the ethmoidal labyrinth and ipsilateral nasal passage during rhinoscopy in one horse and in the paranasal sinuses during sinoscopy in six horses. Fungal culture was positive in five horses with predominance of Aspergillusspp. (n = 3). Surgical debridement was performed under rhinoscopic guidance and sinoscopic guidance through a trephine hole or directly via a bone flap. Medical treatment included topical application directly to the affected area with clotrimazole, enilconazole, nystatin or amphotericin B (mean of 10.1 ± 13.4 applications during hospitalisation) and additional inhalation of nystatin or amphotericin B (mean of 7.5 days of nebulisation during hospitalisation). The mean ± s.d. duration of hospitalisation was 12.9 ± 9.2 days. Six horses were available for long-term follow-up. The mean ± s.d. number of follow-up examinations was 2.8 ± 2.6 consultations. Based on follow-up endoscopic evaluations, it took up to 5 months to observe complete regression of the mycotic plaques. In conclusion, mycotic rhinitis and sinusitis can be effectively treated with repeated surgical debridement and topical antifungal therapeutics, associated with a good long-term prognosis.

七匹马（2013-2019）疑似原发性真菌性鼻炎和鼻窦炎

这份手稿报告了七匹患有真菌性鼻炎和鼻窦炎的马，并描述了临床症状、治疗方法和结果。一匹马在鼻镜检查期间在筛窦的鼻部和同侧鼻道中观察到真菌斑块，在六匹马的鼻窦镜检查期间在鼻窦中观察到真菌斑块。五匹马真菌培养呈阳性，曲霉属优势属 (n = 3)。手术清创是在鼻镜引导下和鼻内镜引导下通过环钻孔或直接通过骨瓣进行的。药物治疗包括直接在患处局部应用克霉唑、恩尼康唑、制霉菌素或两性霉素 B（住院期间平均 10.1 ± 13.4 次应用）和额外吸入制霉菌素或两性霉素 B（住院期间平均雾化 7.5 天）。住院时间的平均值 ± sd 为 12.9 ± 9.2 天。六匹马可供长期随访。随访检查的平均值 ± sd 次数为 2.8 ± 2.6 次咨询。根据后续内窥镜评估，观察真菌斑块完全消退需要长达 5 个月的时间。综上所述，
