Everyday Audiology. a Practical Guide for Health Care Professionals

Description

Everyday Audiology, Second Edition is an invaluable guide for clinicians involved in the care of patients with hearing impairment or balance disorders. Originally written for ENT residents, it has also become a useful resource for other health care professionals who need to synthesize audiologic test results and come up with one cohesive clinical diagnosis. This includes otolaryngologists, family medicine physicians, pediatricians, medical students, audiologists, audiology students, teachers of the hearing impaired, hearing instrument specialists, speech-language pathologists who work with hearing- impaired children, and even physical therapists who provide rehabilitation to patients with balance disorders.

The book contains clinically relevant norms and values that are extremely useful for clinical interpretation. Drawn from lectures given to otolaryngology-head and neck surgery residents and case reports conducted by clinical audiologists at West Virginia University School of Medicine, the book is designed for easy consumption of essential information. Key concepts are presented on left-hand pages and supporting and tabular material on the right.

The book is divided into five parts:

· Part I: Evaluation of Hearing Disorders
· Part II: Evaluation of Balance Disorders
· Part III: Rehabilitation of Hearing Disorders
· Part IV: Otologic/Audiologic Differential Diagnosis
· Part V: References and Notes

For the second edition, there is an addition of an entirely new section. Otologic/audiologic diagnoses that are commonly seen in otology and audiology clinics are presented with a battery of associated audiologic examinations . In this new section (Part IV), the diagnostic code, commonly known as International Classification of Diseases 9th Revision Clinical Modification (ICD-9-CM), is conveniently provided under each case as a reference.

Frequently used audiology terminology and significant clinical criteria are printed in bold. The Current Procedural Terminology (CPT) code, if available, is listed under each test procedure. This book has been found to be helpful in preparation for periodic in-service exams for ENT residents, the ASHA praxis exam for AuD students, and the Step 2 clinical exam for medical students.
