Audiometry and ossicular condition in chronic otitis media [PDF]
Iranian Journal of Otorhinolaryngology, 2009 Introduction: Ossicular chain injury is one of the most common causes of hearing loss in chronic otitis media (COM). Although definite diagnosis of ossicular discontinuity is made intraoperatively, preoperative determination of ossicular chain injury ...

Titanium Biohybrid Middle Ear Prostheses: A Preliminary In Vitro Study
Journal of Functional Biomaterials, 2023 Ossiculoplasty is a surgical operation performed to restore auditory transmission through the reconstruction of the ossicular chain using prosthetics. Tissue bioengineering has assumed a pivotal role in implementing alternatives to conventional ossicular

The Anatomical Record, EarlyView.Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

Segmentation and reconstruction of the 3D geometry of the middle and inner ear
ITM Web of Conferences, 2017 The anatomical model of the ear is of great importance in the design of ossicular prosthesis, cochlear implant electrodes, as well as for the preoperative planning and navigation of surgery. By means of micro-computed tomography (micro-CT) and technology

Plester’s Angled Prosthesis for Ossicular Chain Reconstruction [PDF]
Indian Journal of Otolaryngology and Head & Neck Surgery, 1998 Reconstruction of a defect of the long process of the incus by means of bone chips, cartilage grafts or other material do not give satisfactory long term results. Plester developed therefore an angled prosthesis to reconstruct the defect. It consists of a cross-slit gold bell which is connected with a double band titanium cuff by a tiny gold wire.
