To determine gender-based morphological variations in malleus....
The cross-sectional descriptive study was conducted at the Ear-Nose-Throat and Radiology departments of a public-sector hospital in Karachi, from January 20 to July 23, 2021, and comprised subjects of...
Of the 50 subjects, 25(50%) were males with mean width of the head 3.04±0.34mm, mean length of manubrium 4.47±0.48mm, and mean total length of malleus 7.76±0.60mm. The corresponding values in 25(50%) ...
Width of head, length of manubrium and total length of malleus were different in gender terms, but the total length of malleus was significantly different....
Isolated malleus shaft fractures are rare cases. A commonly reported cause is a finger pulled out from a wet outer ear canal after a shower or bath. The objective was to investigate experimentally the...
Ten fresh-frozen human temporal bones were adapted to allow visual inspection of the structures involved while negative pressure trauma was applied. Thirty malleus bones were broken and the required f...
The temporal bone experiments showed that applied negative pressure in a wet ear canal could not fracture the malleus shaft with only passive counterforce from supporting structures, although the forc...
The combination of a negative pressure created by a finger pulling outward in a wet ear canal and a simultaneous counteracting reflexive force by the tensor tympani muscle were found to be sufficient ...
To compare long-term hearing outcomes following ossiculoplasty with cartilage tympanoplasty with (M) and without (M) the malleus present....
Retrospective chart review....
Tertiary referral center....
One twenty-six patients (18-88 yr of age) undergoing ossiculoplasty with tympanoplasty or tympanomastoidectomy using cartilage tympanic membrane grafts from 1998 to 2012 with at least 5 years of docum...
Short-term hearing results (pure-tone average air-bone gap [PTA-ABG] measured between 60 d and 1 yr after surgery), long-term hearing results (PTA-ABG measured ≥5 yr after surgery), Ossiculoplasty Out...
There were 46 patients in the M group and 80 in the M group. Preoperative PTA-ABG was 23.8 dB for M and 34.5 dB for M (p = 0.00001). Short-term postoperative PTA-ABG was 19.3 dB for M and 18.5 dB for ...
Our data suggest that the malleus is not statistically significant with regard to its impact on final audiometric outcome following ossiculoplasty. This has implications in our clinic, particularly in...
Malleus ankylosis is an uncommon finding during stapes surgery, which can result in functional failure if undetected during primary surgery. Its management can be difficult and different approaches an...
The procedure was carried out in a patient affected by otosclerosis with persistent hearing loss after primary stapes surgery....
Surgical treatment of malleus head fixation through a totally endoscopic transcanal approach during revision stapes surgery....
Pure tone audiometry, speech audiometry....
The patient experienced a complete closure of the air-bone gap. No postoperative vertigo or sensorineural hearing loss were observed....
The present report describes the transcanal endoscopic management of malleus ankylosis during revision stapes surgery, which has not been previously reported in the literature. Pearls related to this ...
Handle of malleus fracture is a rare condition with <100 cases having been reported. The clinical presentation is conductive hearing loss following a history of trauma, typically, during manipulation ...
A 56-year-old female, reported a right ear trauma. She suffered immediate otalgia, hearing loss and nonpulsatile tinnitus. An indistinct umbo was identified on endoscopic inspection and a hypermobile ...
A fracture of the malleus handle should be included in the etiologies of conductive hearing loss after trauma. A careful history, thorough otology examination, and a meticulous analysis of the CT will...
The isolated malleus handle and neck fractures are rare pathology which demands detailed diagnosis and individual treatment plan in every case. Sometimes it could heal without surgery, but in most par...
We compared the sound transmission using different types of total ossicular replacement prostheses (TORP); we then studied the performance of a new TORP that we designed inspired by the columella, the...
Stapedial vibrations were measured on nine freshly frozen human temporal bones with laser Doppler vibrometry. We then compared the performances of eight common TORP positions or designs as well as the...
The TORPs placed in lateral contact with both the TM and the malleus handle outperformed, at most frequencies, those placed only in contact with the TM.The new bird-type prosthesis performed equally w...
If the malleus handle can be retained when placing a TORP, the best sound transmission can be achieved by placing the TORP in contact with both the distal part of the malleus handle and the TM. The go...
In order to study the effect of middle ear malformations on energy absorbance, we constructed a mechanical model that can simulate the energy absorbance of the human ear based on our previous human ea...
Automated image registration techniques can successfully determine anatomical variation in human temporal bones with statistical shape modeling....
There is a lack of knowledge about inter-patient anatomical variation in the temporal bone. Statistical shape models (SSMs) provide a powerful method for quantifying variation of anatomical structures...
Fifty-three cone-beam temporal bone CTs were included for SSM generation. The malleus, incus, stapes, bony labyrinth, and facial nerve were automatically segmented using 3D Slicer and a template-based...
Principal component analysis of middle and inner ear structures revealed novel modes of anatomical variation. The first three principal components for the malleus represented variability in manubrium ...
SSMs of temporal bone anatomy can inform surgeons on clinically relevant inter-patient variability. Anatomical variation elucidated by these models can provide novel insight into function and pathophy...
Malleostapedotomy (MS) is an evolving otology procedure that involves attaching prosthesis to the malleus on one end and the stapes footplate on the other end. It has multiple indications and requires...
