Abstract

Background: Nasal abnormalities are rare in bovines. In humans, nasal deformities are mainly classified as proboscis lateralis or supernumerary nostrils. This report discusses the etiology of triple nostrils in a calf, based on computed tomography, magnetic resonance imaging, and endoscopy.

Case presentation: A female Holstein calf presented with triple nostrils. The following abnormalities were observed: (1) formation of a small and flat blind-ended middle nostril between the right and left nostrils; (2) presence of a hair-bearing surface on the muzzle; (3) abnormal curvature of the nasal septum, resulting in a narrower right nasal cavity due to transformation of the nasal bones; and (4) formation of a bone-like structure within the nasal septum. These findings were similar to those of supernumerary nostrils in humans.

Conclusions: To the best of our knowledge, this represents the first description of a calf with triple nostrils. The use of imaging modalities is necessary for investigating the etiology of triple nostrils.

小牛有三个鼻孔。

背景:牛的鼻腔异常是罕见的。在人类中，鼻畸形主要分为鼻外侧畸形和多鼻孔畸形。本报告讨论小牛三鼻孔的病因，基于计算机断层扫描、磁共振成像和内窥镜检查。病例介绍:一只母荷斯坦牛犊出现三个鼻孔。观察到以下异常:(1)在左右鼻孔之间形成一个小而扁平的盲端中鼻孔;(2)口吻表面有毛;(3)鼻中隔弯曲异常，因鼻骨变形导致右鼻腔变窄;(4)鼻中隔形成骨样结构。这些发现与人类多鼻孔的发现相似。结论:据我们所知，这是对小牛有三个鼻孔的第一次描述。影像学检查是研究三鼻孔病因的必要手段。

期刊介绍： Irish Veterinary Journal is an open access journal with a vision to make a substantial contribution to the dissemination of evidence-based knowledge that will promote optimal health and welfare of both domestic and wild species of animals. Irish Veterinary Journal has a clinical research focus with an emphasis on the effective management of health in both individual and populations of animals. Published studies will be relevant to both the international veterinary profession and veterinary scientists. Papers relating to veterinary education, veterinary ethics, veterinary public health, or relevant studies in the area of social science (participatory research) are also within the scope of Irish Veterinary Journal.
