Evaluation of Postoperative Practices Regarding Packing of the External Auditory Canal.

Background: Packing of the external auditory canal after ear surgery is an established practice in most otologic centers. However, no guidelines exist concerning the management of this process. The aim of the study is to investigate otologists' habits concerning packing of the external ear canal after otologic surgery.

Metabolomic Studies in Inner Ear Pathologies.

Sensorineural hearing loss is the most common sensory deficit. The etiologies of sensorineural hearing loss have been described and can be congenital or acquired. For congenital non-syndromic hearing loss, mutations that are related to sites of cochlear damage have been discovered (e.

Sheep as a large animal model for cochlear implantation.

Introduction: In surgical training, large animal models are more suitable as their anatomy is more similar to humans. In otology, there have been relatively few studies about large animal models for surgical training.

Objective: In this study, we aimed to do a neuroradiologic evaluation and surgical insertion of a cochlear implant electrode array on a sheep head model.

Relationship between Metabolomics Profile of Perilymph in Cochlear-Implanted Patients and Duration of Hearing Loss.

Perilymph metabolomic analysis is an emerging innovative strategy to improve our knowledge of physiopathology in sensorineural hearing loss. This study aims to develop a metabolomic profile of human perilymph with which to evaluate the relationship between metabolome and the duration of hearing loss. Inclusion criteria were eligibility for cochlear implantation and easy access to the round window during surgery; patients with residual acoustic hearing in the ear to be implanted were excluded.
