PURPOSE To evaluate the visualization of middle ear ossicles by ultra-short echo time magnetic resonance (MR) imaging at 3T in subjects over 50 years old. MATERIALS AND METHODS Sixty ears from 30 elder patients that underwent surgical or interventional treatment for neurovascular diseases were included (ages: 50-82, median age: 65; 10 men, 20 women). Patients received follow-up MR imaging inc...

In this research, anatomical descriptions of the structure of the temporal bone and auditory ossicles have been performed based on dissection of ten guinea pigs. The results showed that, in guinea pig temporal bone was similar to other animals and had three parts; squamous, tympanic and petrous .The tympanic part was much better developed and consisted of oval shaped tympanic bulla with many re...

introduction: the lenticular process of the incus succumbs to necrosis in chronic otitis media. few researchers have addressed the issue of autograft incus preservation in the soft tissue of the tragus or mastoid cavity. nonetheless, preservation of the incus in this method during the second stage of ossiculoplasty is a subject that is still up for debate. this study was carried out to demonstr...

The middle ear ossicles are only rarely preserved in fossil hominins. Here, we report the discovery of a complete ossicular chain (malleus, incus, and stapes) of Paranthropus robustus as well as additional ear ossicles from Australopithecus africanus. The malleus in both early hominin taxa is clearly human-like in the proportions of the manubrium and corpus, whereas the incus and stapes resembl...

Objective The purpose of this study is to evaluate our experience with endoscopic repair of ossicular discontinuity at the incudostapedial joint, with or without an intact stapes suprastructure, and present our hearing results. We classify results based on the causative pathology, the type of ossiculoplasty, and type of lesion. We demonstrate the ability to endoscopically place a total ossicula...

We studied the mass growth trajectories of middle ear ossicles and tympanic membrane oval window area in 19 specimens postnatal ages 30–180 days gray short-tailed opossum Monodelphis domestica . weighed skull three with appropriate balances. Using a binocular microscope provided grid, we measured length malleus incus, as well longest axis one perpendicular to it on both stapes footplate. The si...

Objective. To visually compare the Nitinol "smart" stapes prosthesis to conventional manual crimping stapes pistons in temporal bone cadaver specimens. Main Outcome Measures. 10 otolaryngologists were given a photograph of the randomly ordered stapes pistons and asked to use the pictures to answer questions about each stapes piston. The answers to the survey were then recorded for analysis. Res...

OBJECTIVES To report the rare case of a patient with complete incus dislocation after trauma showing normal hearing. METHODOLOGY Physical examination, audiometry, CT of temporal bone, and detection during operation. RESULTS The incus had become remotely located in the mastoid cavity, but the patient showed normal hearing because fibrous connections had preserved bony continuity. CONCLUSIO...

We report a rare case where Q-tip induced mixed hearing loss without perilymph fistula and demonstrate the need for computed tomography imaging with three-dimensional reconstruction where fracture and dislocation of the stapes are suspected. A 28-year-old male experienced an accidental penetrating injury by a Q-tip in the right ear 6 years previously. Temporal bone computed tomography revealed ...
