3D‐Printed Electroanatomic Twins of Cadaveric Cochleae: A Platform for Cochlear Implant Testing
Laryngoscope Investigative Otolaryngology, Volume 11, Issue 4, August 2026.ABSTRACT Objectives Cochlear implants (CIs) can restore hearing to individuals with severe deafness, yet clinical outcomes vary widely because it remains difficult to predict how electrical currents interact with the unique anatomy of each cochlea. A central challenge in auditory rehabilitation is the lack of experimental systems that capture both the ...

The Effect Sodium Salicylate on Concentration of Unknown Compound in Perilymph of Guinea Pig
, 1993 There are some evidences that temporary hearing loss is induced by disturbance of cochlear microcirculation due to the inhibition of prostaglandin synthesis by salicylate, however, the mechanism of salicylate ototoxicity has been still under study ...

Regional Impedance Patterns in Cochlear Implantation: Influence of Demographic and Early Activation
Laryngoscope Investigative Otolaryngology, Volume 11, Issue 4, August 2026.Implantation age is a key determinant of electrode impedance behavior, with a region‐specific effect most pronounced in the apical cochlea. Younger recipients exhibit higher intraoperative impedance followed by a time‐dependent reversal at 6 months.

Intraspecific variation of cochlear morphology in bowhead and beluga whales
The Anatomical Record, Volume 309, Issue 6, Page 1514-1529, June 2026.Abstract The bony labyrinth of the petrosal bone, a distinctive feature of mammal skulls, is often identified in micro‐computed tomography imaging to infer species' physiological and ecological traits. When done as part of a comparative study, one individual specimen is normally considered representative of a species, and intraspecific variation is ...

Drug selection for inner ear therapy
Frontiers in PharmacologyIntroductionOne of the primary tenets in pharmacotherapy is that the applied drug must reach the target tissue at therapeutic concentration. For many therapies intended to treat hearing disorders it has become apparent that we have failed to achieve this

Mannitol and the blood-labyrinth barrier
Journal of Otolaryngology - Head and Neck Surgery, 2017 Background Characterization of the blood labyrinth barrier (BLB) is extremely important to determine whether the BLB can be manipulated pharmacologically. However, experiments to investigate the BLB are technically difficult to perform.

A Case of Multiple Perilymph Fistula Induced by Tympanostomy Tube Insertion [PDF]
, 2010 This controversial diagnosis centers around the phenomenon of perilymph leaking from the inner ear into the middle ear cleft through the oval window, round window or other fissures in the bony labyrinth that may be abnormally patent.
