In light of the controversy reported in previous studies, we conducted this study with the objective of using macroscopy and light microscopy to elucidate the morphology of the discomallear ligament and detail its topographic relationship with other fibrous structures of the temporomandibular joint (TMJ). Two human fetuses with 36 and 37 weeks of intrauterine life were used. Bundles of longitud...

This data article provides additional data related to the research article entitled "Simultaneous intrinsic signal imaging of auditory and visual cortex reveals profound effects of acute hearing loss on visual processing" (Teichert and Bolz, 2017) [1]. The primary auditory and visual cortex (A1 and V1) of adult male C57BL/6J mice (P120-P240) were mapped simultaneously using intrinsic signal ima...

A 36-year-old male who had history of hearing loss since childhood presented with a chronically discharging right ear. HRCT temporal bones revealed non-dependent opacification in the epiand meso-tympanum with medially displaced head of malleus, erosion of incus and the tegmen tympani suspicious for an attic cholesteatoma. In addition, there was a serpiginous structure seen extending across the ...

The over-under myringoplasty is a technique which combines the advantages of both the over and underlay variants and at the same time avoids their complications. By placing the graft deep to the drum remnants, complications of the overlay myringoplasty such as blunting, lateralization and pearl formation are avoided and by passing superficial to the handle of the malleus the main disadvantage o...

Our current understanding of the evolution of the mammalian middle ear was first suggested by embryological studies from the 19th century. Here, site-specific recombinase-mediated lineage tracing was used to define the second branchial arch contribution to the middle ear of wild-type and Hoxa-2 mutant embryos. The processus brevis of the malleus was found to arise from second arch tissues, maki...

The purpose of this study is to examine the relation of the grade of the inflammation of the middle ear and the pathological findings of the tympanic membranes using human serial horizontal sections from 16 temporal bones with otitis media with effusion. As controls, we used 96 normal temporal bones. The results were as follows. 1) In cases with a lot of inflammation cells in the middle ear eff...

The middle ear ossicles are important due to transmission of sound to the inner ear leading to sound understanding. The aim of present study was to determine the anatomical and morphometrical aspects of middle ear ossicles in Makouei sheep fetuses. For this experimental study, eight sheep fetuses at the age of 2 to 3 months were provided from public slaughterhouse; their middle ear ossicles wer...
