Audiological

Notes: Here we have three middle bones again. The arm of the malleus is attached to the eardrum, and the footplate of the stapes is attached to the oval window of the cochlea (inner ear). What they are doing is they transmit vibrations of the eardrum into the cochlea. But here we have a problem. Because the impedance of air and impedance of liquid is really different. Which one is bigger? Impedance in the liquid is much bigger than that of air.  

This comprehensive, richly illustrated textbook provides a systematic approach to frequent otological operations. Procedures in surgery of the ear canal, acute and chronic middle ear diseases, otosclerosis, cochlear implantation and vertigo are visualized step-by-step to acquaint the beginner with proven surgical repertoires. The book is written by two famous experts, and even the experienced surgeon will find valuable hints and suggestions to facilitate routine middle ear operations.  

In our continuing series of hangouts with scientists, engineers, and leaders in the medical technology industry, today we spoke to Dr. Steven LeBoeuf. He's

Two year old Joseph and four year old Jacques are visiting your emergency department today. Jacques has been miserable and pulling at his right ear. His parents are concerned that he may have another ear infection, his fifth this year. As you come back in with the otoscope little Joseph starts to cough and turn blue. What’s happened?

A 26 year old otherwise well man with no medical history of note attended his general practice with a five day history of severe right ear pain and scanty ear discharge. He had returned from holiday one week earlier, where he had been swimming. He had no headache, fever, or systemic upset.

Here is the first part in our three part ENT series looking at recognition and management of common paediatric ENT conditions.This series is based on a presentation by Rahul Santram , adapted by Tessa Davis, and checked by our resident ENT surgeon, Sinéad Davis.  

This case study reviews the differential diagnosis of prostatic utricle cyst, which is primarily diagnosed via imaging. How is it differentiated from other types of urological cysts?  

In human anatomy, the eardrum, or tympanic membrane, is a thin, cone-shaped membrane that separates the external ear from the middle ear in humans and other tetrapods. Its function is to transmit sound from the air to the ossicles inside the middle ear, and then to the oval window in the fluid-filled cochlea. Hence, it ultimately converts and amplifies vibration in air to vibration in fluid. The malleus bone bridges the gap between the eardrum and the other ossicles.[1]
