Is endoscopic stapes surgery safe and are outcomes comparable to microscopic stapes surgery

Endoscopic techniques for visualisation of the middle ear were described in 1967 by Mer and colleagues, and the use of transcanal endoscopic ear surgery (TEES) has since expanded to a wider range of otologic applications including tympanoplasty and excision of...

Electrocochleography and speech-perception in cochlear implant (CI) patients

It is difficult to predict the speech perception outcomes of cochlear implantation. Previous studies showed that total response electrocochleography (ECochG-TR) may explain the variance in CI performance better than biographic, audiometric, and surgical factors combined. The authors’ objectives were to...

Pre-clinical development of magnetic delivery of therapy to middle and inner ears

Why are we developing this technology? A key problem in drug delivery is getting the therapy to the right place in the body, which is especially challenging for targets that are small, deep and are protected or surrounded by anatomical...

Multifrequency tympanometry

There are many good reasons to start using multifrequency tympanometry as opposed to a traditional, single 226Hz probe tone. Here, Leigh Martin of Interacoustics discusses the uses and benefits. Tympanometry is a core test in the audiologist’s test battery. In...

The first level of lymphatic spread in well-differentiated thyroid carcinoma is to the central compartment of the neck, namely, the paratracheal, prelaryngeal and pretracheal lymph nodes. Central neck dissection may carry an increased morbidity, namely, hypoparathyroidism and recurrent laryngeal nerve...
