• However, there may be considerable freedom of motion and some loss of energy at the joint between the incus and the stapes because of their relatively loose coupling. (britannica.com)
  • X-linked deafness with stapes gusher, also referred as X-linked deafness-2 (DFNX2, OMIM 304400), is characterized by progressive conductive and sensorineural hearing loss and a pathognomonic temporal bone deformity that includes dilatation of the internal auditory canal (IAC) and a fistulous connection between the IAC and the cochlear basal turn. (beds.ac.uk)
  • RESULTS: Optimal tight crimping of the stapes piston revealed consistent good sound transfer function ranging from 0 to 7 dB loss, and loss remained, on average, at 2 dB. (uzh.ch)
  • Autosomal dominantly inherited or de novo variants in NOG lead to a spectrum of joint/digit abnormality disorders with or without conductive hearing loss, including Type B2 brachydactyly (BDB2), multiple synostoses syndrome 1 (SYN1), stapes ankylosis with broad thumbs and toes (Teunissen-Cremers syndrome), proximal symphalangism 1A (SYM1A), and tarsal-carpal coalition syndrome (TCC).

  • The conductive hearing loss is usually due to ankylosis of the stapes. (hindawi.com)
  • Introduction Otosclerosis is a primary disease of the temporal bone that leads to stapes ankylosis . (bvsalud.org)
  • are passed on to the stapes, and the whole ossicular chain moves as a single mass. (britannica.com)
  • 4. The method of claim 2 , where the interrupting the ossicular chain step is accomplished by separating an incus from a stapes and mallus, and then fixing the position of the incus within the middle ear. (google.com)
  • Preoperative recognition of this entity plays an important role in the identification of patients at risk for perilymphatic stapes gushing and avoids worsening of sensorineural hearing loss. (ajnr.org)
  • A 14-month-old boy, with sensorineural hearing loss in both ears, showed typical radiological features of X-linked stapes gusher on preoperative temporal bone computed tomography (CT) for cochlear implantations. (beds.ac.uk)
  • Although the relationship between GATA3 and inner ear development has been studied, a case of HDR syndrome with sensorineural deafness mimicking an X-linked stapes gusher has not previously been reported. (beds.ac.uk)
  • Curiously, while structures in the general locality of the stapes have been described fully in recent publications, the ossicle itself has received little attention. (edu.au)
  • The stirrup-shaped stapes is the smallest ossicle with a hollow space in the middle. (innerbody.com)
  • Depending on the underlying cause of progressive deafness and stapes fixations, there may be other associated signs and symptoms. (cdc.gov)
  • The central cavity of the stapes, the obturator foramen, is due to the presence embryologically of the stapedial artery, which usually regresses. (wikipedia.org)
  • The stapes begins with a tiny cylindrical head where it meets the incus before splitting into two parallel columns of bone known as the anterior and posterior crus. (innerbody.com)
  • The goal of this study is to present the numerous observed anomalies based on a large number of cases, and to describe anatomical variations and malformations of the stapes using high-resolution computed tomography (CT), after proper reorientation in the "axial stapes" plane. (univ-brest.fr)
  • The stapes is homologous with the entire stapedial structure of reptiles, which in turn was derived from the hyomandibular arch of primitive vertebrates. (britannica.com)
  • The stapes is the third bone of the three ossicles in the middle ear. (wikipedia.org)
  • Our middle ear implants and stapes implants are available in multiple combinations of biocompatible materials, shapes, and sizes for many different anatomies and conditions. (medtronic.com)
  • The stapes is commonly described as having been discovered by the professor Giovanni Filippo Ingrassia in 1546 at the University of Naples, although this remains the nature of some controversy, as Ingrassia's description was published posthumously in his 1603 anatomical commentary In Galeni librum de ossibus doctissima et expectatissima commentaria. (wikipedia.org)
  • RESULTS: Sixty-one stapes in 47 patients were found to have one or more congenitally abnormal shapes (bilateral anomalies were found in 14 of these patients). (univ-brest.fr)
  • The stapes is one of three ossicles in mammals. (wikipedia.org)
  • The primitive stapes in the common ancestor of mammals and therapsids was probably columelliform and had a stapedial foramen for the passage of the stapedial artery. (geoscienceworld.org)
