Semi implantable bone conduction devices: challenges and developments

Bone conduction mechanisms and history of bone conduction aids Bone conduction hearing devices work by stimulating hair cells via the bone conduction hearing pathways. These pathways are less well understood than the air conduction pathways, but recent research has shown...

PHACON artificial bone models for ENT training

Simulation, both in training and clinical practice, has become an increasingly important facet of a surgeon’s life. The escalating costs of cadaveric material makes synthetic alternatives an attractive proposition but, up until recently, these artificial versions have lacked the material...

Which bone conduction implant (BCI) device to use?

Bone conduction implants (BCI) are alternatives when the use and benefit of conventional, prosthetic equipment is limited or contraindicated in patients who suffer from conductive, mixed and single-sided deafness. They are broadly divided into two main groups delivering vibration directly...

The role of imaging in differentiating rare temporal bone neoplasms

This paper provides a useful tool to assist in determining the diagnosis of benign neoplasms of the temporal bone using readily available imaging modalities. Specifically, this group have looked at chondrosarcoma, an expansile hypermetabolic mass lesion usually found in the...

The Temporal Bone: Anatomical Dissection and Surgical Approaches

The Temporal Bone: Anatomical Dissection and Surgical Approaches does exactly what it says on the tin. It is an excellent combination of anatomical atlas and dissection manual for temporal bone surgical procedures, designed to be kept open at the benchside...

Revision stapedectomy with bone cement works well!

Revision stapes surgery is notoriously difficult and results are worse than in primary surgery. This group in Utah have described the use of hydroxyapatite bone cement to stabilise the nitinol prosthesis they use in revision surgery due to incus necrosis...

Temporal Bone Dissection Guide - Second Edition

In the second edition of this popular dissection guide the authors have raised the bar even higher, expanding on the infratemporal and middle fossa dissection guide. There is also a brief description of the use of endoscopes in middle ear...

Virtual reality surgical simulation for the temporal bone

This prospective study looked at 15 otorhinolaryngology residents in Belgium to see if using the VOXEL-MAN Tempo surgical simulator system improved their understanding of temporal bone radiological anatomy. As a secondary aim, they also assessed whether there was any improvement...

How to tell if a bone anchored hearing device is working?

Bone anchored hearing aids are becoming increasingly more commonplace with more than 120,000 users worldwide. These devices are based on the principle of direct bone conduction, where sound is transmitted directly through the skull via a titanium implant to the...

Experience of the Sophono transcutaneous bone conduction system

This article is a frank discussion of the authors’ experience implanting these devices. The principle of the device is surgical implantation of a bilobed magnet within a bony well in the cranium (similar position to BAHA). The implant is a...

Treatment of incus lysis with hydroxyapatite bone cement

Middle ear implants provide a suitable alternative for some patients with a certain degree of sensorineural or mixed hearing loss, not wanting a hearing aid. Vibrant SounBridge® (VSB) middle ear implant (MEI), of Med-El®firm, is one such implant. In this...

Bone thickness and split pattern in mandibular osteotomies

This paper looked at 63 sagittal split ramus osteotomy sites. The type of split was classified according to the Plooij paper and bone measurements were taken at four sites. Of these sites, the thickness of the bone in one point,...
