Assessing Body Temperature - Tympanic membrane01:14

Assessing Body Temperature - Tympanic membrane

1.3K
Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...

The Cochlea01:13

The Cochlea

52.0K
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

Anatomy of the Ear

13.0K
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Summary

Voluntary tensor tympani contraction causes a low-frequency mixed hearing loss. This audiometric finding, characterized by specific threshold shifts, aids in diagnosing tensor tympani dysfunction.

Area of Science:

  • Audiology
  • Otolaryngology
  • Neuroscience

Background:

  • The tensor tympani muscle's contraction may produce a distinct audiogram.
  • Previous studies suggested a link between tensor tympani contraction and low-frequency conductive hearing loss.

Purpose of the Study:

  • To demonstrate the specific audiometric findings associated with voluntary tensor tympani muscle contraction.
  • To characterize the impact of tensor tympani contraction on air and bone conduction thresholds.

Main Methods:

  • Five volunteers capable of voluntary tensor tympani contraction were enrolled.
  • Tympanometry confirmed muscle contraction.
  • Conventional audiometry, including air and bone conduction testing, was performed with and without contraction.

Main Results:

  • Voluntary tensor tympani contraction resulted in a low-frequency mixed hearing loss.
  • At 250 Hz, air conduction thresholds increased by 22 dB, and bone conduction thresholds increased by 10 dB.

Conclusions:

  • This study is the first to document a low-frequency mixed hearing loss linked to tensor tympani contraction.
  • These findings may assist in diagnosing conditions related to abnormal tensor tympani function.
  • Tensor tympani contraction should be considered in the differential diagnosis for low-frequency mixed hearing loss.
