“…Similar to the reported data in the case of humans [ 5 , 21 , 26 , 28 , 34 , 35 , 36 ] or other primates [ 5 , 13 , 16 , 21 , 22 , 25 , 37 , 38 , 39 ], the ossicular assembly in Chlorocebus aethiops sabaeus consists of three well-individualized bony pieces located in the cavity of the middle ear ( auris media ), the most laterally placed and the largest being the malleus.…”

Otological studies rely on a lot of data drawn from animal studies. A lot of pathological or evolutionary questions may find answers in studies on primates, providing insights into the morphological, pathological, and physiological aspects of systematic biological studies. Our study on auditory ossicles moves from a pure morphological (macroscopic and microscopic) investigation of auditory ossicles to the morphometrical evaluation of several individuals as well as to some interpretative data regarding some functional aspects drawn from these investigations. Particularities from this perspective blend with metric data and point toward comparative elements that might also serve as an important reference in further morphologic and comparative studies.

“…One of the most frequent traumatic complications that occur at the level of the petrosal bones is the ones affecting the auricular ossicular assembly (Kurtul et al., 2003). Similarly to some available literature data, in species like the wolf (Gürbüz et al., 2019), rabbits (Guan et al., 2019), non‐human primates (Borin et al., 2008), humans (Guan et al., 2019) and sheep (Simaei et al., 2017), in the goat one can describe, at the level of the tympanic cavity, an assembly of three auditory ossicles. This comes in contrast to some other species like the donkey, where consulted literature (Nazih, 2017) mentions the existence of the 4th auditory ossicle—the lenticular bone.…”

The present paper deals with a detailed description of the auditory ossicles in Capra hircus. The paper focuses on the morphological and morphometrical description of the ossicular assembly, formed by malleus, incus and stapes. The malleus (overall length, as average‐ 8.16 mm) comprises the head of malleus (Caput mallei), a slightly strictured part—neck (Collum mallei) with 3 distinctive processes (lateral, rostral and muscular) (Processus lateralis, Processus rostralis and Processus muscularis) and a handle (Manubrium mallei). The head of malleus has an oval aspect with an obtuse articular surface on its medial surface (Facies articularis). The neck is evident with three bony processes described—the anterior, almost triangular, the muscular one quite reduced and the lateral one which is the most developed one. The manubrium is the longest sector—4.4 mm and appears as a slightly curved piece. The incus presents a body of 1.3 mm and two processes—the short and long crus (Crus breve and Crus longum). The overall shape of the ossicle resembles a biradicular molar. The lenticular process is a continuation of the distal part of the long crus. The stapes—the smallest in size of the three ossicles (2.7 mm), has a head (Caput stapedis), an anterior (Crus rostrale) and a caudal (Crus caudale) arm and a footplate (Basis stapedis). The two processes are slightly different in size and morphology, delimiting the intercrural space that shows the presence of a bony spicule. The footplate (1.6 mm2 area) is ellipsoidal, with an anterior narrower extremity.

This study aims to determine morphological features of certain aural formations, varietal characteristics, and arterial supply in fetal development period in cattle. For this purpose, ears of 10 bovine fetuses in mid-gestation were evaluated. Organ morphology and vascularization in prenatal life were investigated by using corrosion cast technique. It was observed that some aspects of osseous formation and vascular organization in middle and inner ears were not developed completely in the first half of gestation; in addition, cochlea did not its snail-like structure yet, lateral semicircular canal was rather low compared to others and auditory ossicles did not take its final shape. The feeding blood vessels of inner ear were found to demonstrate three different distribution patterns, whereas feeding pattern in middle ear was very similar in many specimens. The presence of stapedial artery was also identified. Differences and similarities with other some species were assessed in terms of both general morphological structure and vascular organization. From this regard, it is thought that this study will constitute a comparative model for both humans and other species and provide morphological contributions since there is not sufficient literature on species-specific ear morphology in the field of veterinary anatomy in contrast to the abundance of studies on humans.
