The genus Glyphipterix Hübner is reviewed in mainland China, with eight species and one subspecies treated. Glyphipterix semicircularis sp. nov., G. liui sp. nov., and G. miniata continentalis ssp. nov. are described as new to science. Glyphipterix gamma Moriuti et Saito, 1964, G. regula Diakonoff et Arita, 1976, and G. gemmula Diakonoff et Arita, 1976 are firstly recorded from mainland China. ...

The presence of three interconnected auditory ossicles in the middle ear is a defining characteristic of mammals, and aspects of ossicle morphology are related to hearing sensitivity. However, analysis and comparison of ossicles are complicated by their minute size and complex three-dimensional shapes. Here we introduce a geometric morphometric measurement protocol for 3D shape analysis based o...

role in alerting us to nearby activities, in the appreciation of music, and especially in human communication. Airborne sounds vibrate the tympanum, which transmits the oscillations successively to the malleus, incus, and stapes of the middle ear. Moving like a piston, the last of these miniscule bones alternately increases and decreases the pressure within the cochlea, a chickpea-sized organ t...

the aim of this study was to determine the anatomical features of the auditory ossicles in rat. twenty temporal bones from 10 adult rats were used. the features of the ossicles were assessed with an ocular micrometer and photographed by a stereomicroscope. finally, all data were evaluated and analysed using the sigma statt software. temporal bone in rat was similar to other animals consists of ...

introduction: otosclerosis is a disease of bony labyrinth. structural changes in the labyrinth often cause ossicular fixation, and thus conductive hearing loss. the purpose of this study was to evaluate middle ear exploration findings and frequency of ossicular and footplate area anomalies in patients with suspected otosclerosis referred to amiralmomenin and golsar hospitals in rasht, iran.   m...

Introduction: The use of ossicular graft material in ossicular chain reconstruction has significantly improved hearing results hearing after tympanoplasty and tympanomastoid surgery for chronic otitis media. Today, otologists have a wide array of tools from which to choose, but may find it difficult to know which middle ear implant works best.   Materials and Methods: A prospective study of 80 ...
