Insights

Tympanometry provides valuable insights into middle ear function in young children, aiding early diagnosis of conditions like secretory otitis media. While initial results may show abnormalities, many resolve spontaneously, highlighting the need for careful interpretation alongside clinical evaluations.

Area of Science:

  • Pediatric audiology
  • Otolaryngology

Background:

  • Clinical hearing examinations are standard in mother and child clinics.
  • The added value of tympanometry following initial clinical assessment requires further investigation.

Purpose of the Study:

  • To evaluate the additional diagnostic information provided by tympanometry after a clinical hearing examination in young children.
  • To assess the concordance of tympanometry with other audiological tests (BOEL, audiometry) across different age groups.

Main Methods:

  • A cohort of 182 children (6 months to 4 years) underwent clinical hearing examination followed by tympanometry.
  • Data on tympanometry results, BOEL test, audiometry, and referrals were collected.
  • Correlation between parental perception of hearing, child's health status, and specialist referrals was analyzed.

Main Results:

  • 39% of ears examined showed pathological tympanograms, with most normalizing spontaneously.
  • Low concordance between tympanometry and BOEL test in infants (6-12 months).
  • Fair concordance between tympanometry and audiometry in 4-year-olds.
  • Tympanometry contributed to 11 of 27 referrals to an ear, nose, and throat specialist.

Conclusions:

  • Tympanometry aids in the early diagnosis of secretory otitis media.
  • It helps parents understand temporary middle ear dysfunction in children.
  • The diagnostic utility of tympanometry varies by age and should be interpreted alongside clinical findings.

Temperature Measurement Sites01:14

Temperature Measurement Sites

A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Assessing Body Temperature - Tympanic membrane

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...

Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.  
Step 3: Assess the patient's forehead...

Anatomy of the Ear01:16

Anatomy of the Ear

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...
Physical Assessment of the Respiratory Tract III: Percussion01:29

Physical Assessment of the Respiratory Tract III: Percussion

The respiratory system, fundamental to life, consists of complex structures responsible for gas exchange. The percussion assessment is critical to understanding this system's health and functionality. This non-invasive assessment technique allows healthcare providers to evaluate the density or aeration of the lungs, thereby identifying potential abnormalities.
