“…Another approach is to take measurements directly on the objects, which was the case in the studies of Dass et al (1966) Dass et al (1969), Harneja and Chaturvedi (1973), Arensburg et al (1981), Awengen et al (1995), Bhatnagar et al (2001), Unur et al (2002), and Ramirez and Ballesteros (2013). The small size of the ossicles is challenging in the direct measurement procedure using calipers.…”

Human auditory ossicles, the malleus, the incus, and the stapes, are located in the tympanic cavity in the temporal bone and through forming a chain for the sound transmission from the tympanic membrane to the cochlea, they play an important role in the hearing process. Despite their clinical, phylogenetic, and evolutionary significance, the morphometry of the human ear bones has not been examined systematically. The ear ossicles are the smallest bones of the human skeleton, attaining their final size and morphology already at birth. Initially, they have been found to exhibit minimal morphometric variation, but further studies brought the opposite results. The aim of this study was to examine the morphometric variation of human auditory ossicles recovered from medieval and postmedieval subadult skeletons from Poland, Central Europe.The analysis involved in a total of 166 ear bones. Their measurements were performed on microscopic images using CorelDraw x4, according to a protocol of Quam and Rak with modification of Flohr et al. and Wadhwa et al. Our study showed a significant metric variation in the measurements taken at areas of the greatest morphological variability of the ossicles. We found that greater linear dimensions were associated with lower values of angular measurements. These results reveal the inherent variation found in these supposed functionally constrained structures. Representation of even greater number of populations, time periods, and developmental stages are needed. Further study will expand our understanding of the global scope of variation found in ear ossicular morphology and its functional implications for paleoanthropology.

The ear ossicles transmit sound from the external ear to the inner ear. The aplasia, hypoplasia, erosion, and trauma to the ear ossicles cause conductive deafness, which can be corrected by ossiculoplasty, for which detailed knowledge of morphometry of the ear ossicles is very essential. So, the study was carried out. The aim of the study is to analyze the morphometric data and correlate it with clinical significance. The study was conducted in the Department of Anatomy using 47 malleus, 46 incus, and 10 stapes of known age, sex, and side. The various parameters of these ossicles were measured with vernier calipers. The parameters were compared with other studies, and associated clinical significance was elaborated. The means in mm of the total length, length of handle, length, and width of the head of the malleus are 6.8 ± 0.5, 4.4 ± 0.4, 2.7 ± 0.3, and 2.6 ± 0.3, respectively. The mean of the total length, width, length of long process and short process of incus in mm are 6.7 ± 0.5, 4.7 ± 0.4, 3.7 ± 0.3, and 2.7 ± 0.4, respectively. The mean of the total height, length, and width of the foot plate of stapes in millimeters are 3.2 ± 0.4, 2.7 ± 0.2, and 0.8 ± 0.3, respectively. The various parameters associated with ear ossicles of different populations were found to vary on the right and left sides and also in different sexes. The data will be of immense use in ossiculoplasty and the designing of prostheses to restore hearing.

Objective. In this report, we review the recent literature (ie, past 4 years) to identify advances in our understanding of the middle ear-mastoid-eustachian tube system. We use this review to determine whether the short-term goals elaborated in the last report were achieved, and we propose updated goals to guide future otitis media research.Data Sources. PubMed, Web of Science, Medline.Review Methods. The panel topic was subdivided, and each contributor performed a literature search within the given time frame. The keywords searched included middle ear, eustachian tube, and mastoid for their intersection with anatomy, physiology, pathophysiology, and pathology. Preliminary reports from each panel member were consolidated and discussed when the panel met on June 11, 2015. At that meeting, the progress was evaluated and new short-term goals proposed.Conclusions. Progress was made on 13 of the 20 short-term goals proposed in 2011. Significant advances were made in the characterization of middle ear gas exchange pathways, modeling eustachian tube function, and preliminary testing of treatments for eustachian tube dysfunction.Implications for Practice. In the future, imaging technologies should be developed to noninvasively assess middle ear/eustachian tube structure and physiology with respect to their role in otitis media pathogenesis. The new data derived from these structure/function experiments should be integrated into computational models that can then be used to develop specific hypotheses concerning otitis media pathogenesis and persistence. Finally, rigorous studies on medical or surgical treatments for eustachian tube dysfunction should be undertaken.
