Rhinne examination I. Understanding The ear has a function as a hearing aid and maintaining balance. According to its anatomical structure, the ear can be divided into three parts, namely the outer ear, middle ear and inner ear. Physiologically, the hearing process occurs through a series. All sounds heard can cause sound waves to move. These sound waves are transmitted through air to the tympanic membrane which causes this membrane to vibrate. The auditory oxycles transmit sound waves to the fenestra ovalis and then to the inner ear fluid. The inner ear fluid transmits sound waves to the receptors of the cochlear branch of nerve fiber VIII. Next, the cochlear nerve sends impulses to the auditory control center in the temporal lobe of the cerebrum. This hearing is caused by stimulation of this area of the brain.Ear examination is used to determine the condition of the outer ear, ear canal, eardrum and hearing condition. The Rinne test is an audiometric test that is used to measure hearing acuity, as well as to determine the localization of anatomical damage that causes hearing loss. II. Objective The Rinne test is used to compare bone conduction with air conduction in one patient's ear. III. Indication Criteria for patients experiencing hearing loss include: 1. Mild, still able to hear at an intensity of 20-40 dB 2. Medium can still hear at an intensity of 40-60 dB 3. Severely unable to hear at an intensity of 60-80 dB 4. It is very difficult to be unable to hear at an intensity >80 dB IV. Procedure 1. Hold the tuning fork by the stem and strike it against the palm or knuckle of the opposite hand 2. Place the tuning fork stem on the client's mastoid process 3. Encourage the client to notify the examiner when they no longer feel vibrations 4. Then lift the tuning fork and quickly place it in front of the client's outer ear canal 5. Instruct the client to tell whether they still hear the sound or not 6. Record the results of the hearing examination. There are 3 interpretations of the Rinne test results: a. Normal: positive Rinne test(Air Conduction > Bone Conduction) b. Conduction deafness: negative urine test(Air Conduction < Bone Conduction) c. Perceptual deafness, there are 3 possibilities: 1) If in position II the patient still hears the vibration of the tuning fork. 2) If in position II the patient is unsure whether he can hear or not (Rinne test: +/-) 3) Pseudo negative: occurs in people with deafness in the right ear who perceives in position that they hear in the normal left ear, so it first appears
