Feasibility and Outcomes of an Active Osseointegrated Bone Conduction Implant in Children as Young as 5 Years of Age.

Introduction: This study reviews the feasibility of implanting active osseointegrated bone conduction devices in young children, below the prior age for FDA indication (<12 years), which has recently been reduced to 5 years. Outcomes included differences in adverse event rates and operative time between two groups (<12 and 12 years or older).

Materials And Methods: This study is a retrospective review of children receiving active osseointegrated bone conduction devices at a tertiary referral center academic hospital.

Caution in Transnasal Balloon Dilation of the Eustachian Tube: Middle Ear Penetration of Catheter Tip in a Cadaveric Model.

Objective: To investigate the degree to which transnasal eustachian tube (ET) dilation balloon catheters are able to be passed through the ET in a cadaver model.

Patients And Interventions: A cadaveric study of 8 cadaver heads (16 ears), which underwent transnasal ET insertion with a 3 × 20-mm balloon catheter with transtympanic endoscopic visualization and grading.

Results: Catheter tip incursion into the protympanum or mesotympanum occurred in all ears.

Prevention of Otic Barotrauma in Aviation: A Systematic Review.

Objective: To conduct a systematic review of the published evidence relating to the prevention of otic barotrauma in aviation. In particular, this review sought to identify procedures, techniques, devices, and medications for the prevention of otic barotrauma as well as evaluate the evidence relating to their efficacy.

Data Sources: Ten databases including Embase, MEDLINE, the Cochrane Database of Systematic Reviews, and the Cochrane Central Register of Controlled Trials were searched using the full historical range.

Endoscopically Guided Transtympanic Balloon Catheter Dilatation of the Eustachian Tube: A Cadaveric Pilot Study.

Objective: To assess the feasibility, safety, and efficacy of transtympanic balloon catheter dilatation of the Eustachian tube (ET) in a cadaver model.

Patients And Interventions: A cadaveric study of 10 cadaver heads, which underwent unilateral transtympanic dilatation of the ET with a 3 × 20 mm balloon catheter with full endoscopic guidance and visualization.

Results: Procedural safety was demonstrated, with no damage to any essential structures found.

Retention of topographical anatomical knowledge following surgeon-facilitated whole-body dissection.

Background: Topographical anatomy has been taught to medical students by cadaver-based dissection for centuries. However, there is a void in the literature assessing the long-term retention of anatomical knowledge by medical students following teaching by whole-body dissection. The purpose of this paper was to assess both the acquisition and retention of topographical anatomical knowledge gained by medical students undertaking an elective whole-body dissection course.
