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 pa...

HYPOTHESIS It was hypothesized that the differences in the bioacoustic performance of ossicular replacement prosthesis designs, and insertion positions, could be quantified using finite element analysis. BACKGROUND Many designs of prosthesis are available for middle ear surgery. The materials used, and the shape of the implants, differ widely. Advances in computer simulation technologies offe...

This study was conducted to find out the status of the ossicles in cases of chronic suppurative otitis media (CSOM). One hundred and fifty cases of CSOM, who underwent surgery, were included and their intra-operative ossicular chain findings noted. Ossicular erosion was found to be much more common in unsafe CSOM than in safe CSOM. Malleus was found to be the most resistant ossicle to erosion w...

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...

Otologic injury associated with fatal and nonfatal lightning strikes has been sporadically reported in the literature. The most common acoustic insult is a conductive hearing loss secondary to rupture of the tympanic membrane. Although conjecture has been made of the theoretic possibility of ossicular injury from lightning strike, to our knowledge, none has been demonstrated intraoperatively or...

SUMMARY A subset of patients presents with unilateral conductive hearing loss, a normal pinna or grade I microtia, and mild external auditory canal stenosis. The physical findings of microtia and a small external canal are commonly absent or subtle in this group of patients, who are being commonly referred for imaging to evaluate isolated conductive hearing loss. We present a case series of pat...

INTRODUCTION Different types of titanium prostheses are used for different types of ossicular chain reconstruction (OCR). However, various ossicular chain problems require different types of reconstruction (incus or prosthesis). Recently, Vincent et al. published a new type of ossiculoplasty with a malleus replacement prosthesis (MRP). The details of this new prosthesis are described in their a...

introduction: even though modern technology progresses so rapidly, annals of otology are replete with so many challenging article, which often compare various types of prosthesis. since there has not been a prospective randomized clinical trial study which compares the hearing result of total ossicular replacement prosthesis made of titanium with omega connector and polycel in the literature, w...

The hypertrophied malleus in the middle ear of some golden moles has been assumed to be an adaptation for sensing substrate vibrations by inertial bone conduction, but this has never been conclusively demonstrated. The Cape golden mole (Chrysochloris asiatica) exhibits this anatomical specialization, and the dynamic properties of its middle ear response to vibrations were the subjects of this s...
