According to our clinical experience, the gold standard for ossicular chain reconstruction is the incus interposition, which has shown a very low percentage of extrusion in long-term follow-up with excellent audiological outcomes (except tympanosclerosis) in our patients. There is no study using transcanal approach for type 2 tympanoplasty with incus interposition. In order to achieve success in audiological outcomes after incus interposition, the incus needs to be lightened. In addition, the removal of incus has facilitated the cleaning of pathological tissues in the middle ear...

Functional failure of total ossicular replacement prostheses (TORP) is often due to secondary displacement, ranging from simple subluxation to prosthesis extrusion following recurrence of severe tympanic membrane retraction. Several surgical techniques have been proposed to stabilize a TORP, mostly using superimposed non-organic or resorbable heterologous materials. We describe a simple so-called "tumulus" surgical technique that limits prosthesis displacement and extrusion, regardless of the type of TORP, by using a few fragments of autologous cartilage that are always available and perfectly tolerated at no cost...

Active middle ear implants are surgically implanted prosthesis, which intend to stimulate the ossicular chain or the inner ear fluids through the oval or round windows. These implants may be useful for the treatment of certain patients with sensorineural hearing loss as well as for conductive or mixed hearing loss. This clinical guide attempts to summarize the current knowledge concerning the basic characteristics and indications of the most commonly used middle ear implants, including Vibrant Soundbrige (Med-el, Innsbruck), Carina (Cochlear, Australia), and CodacsTM ...

Hearing research has long been facilitated by rodent models, although in some diseases, human symptoms cannot be recapitulated. The common marmoset (Callithrix jacchus) is a small, easy-to-handle New World monkey which has a similar anatomy of the temporal bone, including the middle ear ossicular chains and inner ear to humans, than in comparison with that of rodents. Here, we report a reproducible, safe, and rational surgical approach to the cochlear round window niche for the drug delivery to the inner ear of the common marmoset...

The La Ferrassie 1 (LF1) skeleton, discovered over a century ago, is one of the most important Neandertal individuals both for its completeness and due to the role it has played historically in the interpretation of Neandertal anatomy and lifeways. Here we present new skeletal remains from this individual, which include a complete right middle ear ossicular chain (malleus, incus, and stapes), three vertebral fragments, and two costal remains. Additionally, the study of the skeleton has allowed us to identify new pathological lesions, including a congenital variant in the atlas, a greenstick fracture of the left clavicle, and a lesion in a mid-thoracic rib of unknown etiology...

OBJECTIVES: In Ethiopia, 2-stage operations with middle ear prostheses are economically unfavorable. We hypothesized that single-stage autologous ossiculoplasty results in acceptable tympanic membrane (TM) and hearing improvements in a setting of limited resources. METHODS: One hundred eighty-eight patients (197 ears) who underwent 1-stage autologous ossiculoplasty for ossicular dysfunction are presented. All but 14 of these ears also had perforations of the TM...

OBJECTIVES: Congenital cholesteatoma (CC) occurs less commonly than acquired cholesteatoma (AC), and bilateral CC (BCC) is even more rare with only 38 such cases having been reported in the past 42 years. Because of the rarity of this condition, providers confronted with cases of BCC may find it difficult to treat while balancing complete removal of disease, optimal hearing outcomes, and minimized surgical burden in the pediatric patient. This review alerts physicians that BCC occurs, highlights past presentations and management strategies, describes the considerations in treatment and offers an algorithm helpful in the management of BCC...

The presence of external elements is a major limitation of current hearing aids and cochlear implants, as they lead to discomfort and inconvenience. Totally implantable hearing devices have been proposed as a solution to mitigate these constraints, which has led to challenges in designing implantable sensors. This work presents a feasibility analysis of a MEMS piezoelectric accelerometer coupled to the ossicular chain as an alternative sensor. The main requirements of the sensor include small size, low internal noise, low power consumption, and large bandwidth...

BACKGROUND: Total ossicular replacement prostheses (TORP) are often used to re-establish ossicular coupling of sound in an ear lacking a stapes supra-structure. The use of TORPs, however, is associated with a 2/3 five year failure rate due to their anatomic instability over time in the middle ear. The use of autologous fat to try and stabilize TORPs may improve long-term results with this challenging ossicular reconstruction technique. METHODS: A cadaveric temporal bone model was developed and laser Doppler vibrometry was used to measure and record round window membrane vibration in response to sound stimulation under the following conditions: normal middle ear, middle ear filled with fat, normal middle ear with TORP prosthesis, TORP prosthesis with fat around its distal end and TORP prosthesis with fat filling the middle ear...

OBJECTIVE: When the thresholds for VR reconstruction from multi-slice CT images are changed, problems develop when assessing pathologies in the absence of standardized thresholds. The advantages of CBCT include lower radiation exposure compared with other techniques and better visualization of small ear structures. However, a disadvantage is that the scanner provides unstandardized gray scale values, thus not CT numbers (Hounsfield units, HU). METHODS: We analyzed 88 sets of volume data obtained from temporal bones...

Objective: Chronic otitis media most commonly causes an ossicular chain defect in incus. Different materials can be used for repair of this defect. In this study, the hydroxyapatite prosthesis, used for repair of the incus defect, was compared with the incus interposition. Methods: Between 2010 and 2016, 27 female and 16 male patients who underwent ossiculoplasty due to an incus defect were studied retrospectively. Patients' hearing results at the sixth month were compared...
