Cardiovascular System Abnormal Findings II: Auscultation01:25

Cardiovascular System Abnormal Findings II: Auscultation

Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

Hearing01:31

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
Auditory Pathway01:15

Auditory Pathway

Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.
When viewed cross-sectionally, the cochlea reveals the scala vestibuli and scala tympani flanking the...
Heart Sounds01:15

Heart Sounds

Heart sounds are generated by the turbulence in blood flow due to the closing of heart valves. These sounds are best perceived slightly away from the valves, where the blood flow disseminates the sound.
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V) valves at the...
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...

Summary
This summary is machine-generated.

Pseudo-sudden deafness, linked to acute otitis media, causes hearing loss and reduced speech discrimination. Prompt treatment of otitis media can improve hearing outcomes in many patients.

Area of Science:

  • Otolaryngology
  • Audiology
  • Neurology

Background:

  • Acute otitis media can lead to sensorineural hearing loss with reduced speech discrimination.
  • This condition, termed pseudo-sudden deafness, is often misdiagnosed as idiopathic sudden sensorineural hearing loss.

Purpose of the Study:

  • To describe the clinical presentation and management of pseudo-sudden deafness.
  • To differentiate this entity from idiopathic sudden sensorineural hearing loss.

Main Methods:

  • Eight adult patients with asymmetric sensorineural hearing loss post-otitis media were included.
  • Diagnosis was confirmed via audiometry, MRI (to exclude retrocochlear disease), and myringotomy for serous otitis media (SOM).
  • Treatment involved addressing SOM and the sensorineural component with antibiotics, steroids, and tympanostomy tubes.

Main Results:

  • Six of eight patients showed improved speech discrimination or pure tone thresholds after treatment.
  • Audiograms demonstrated positive changes post-intervention for SOM and sensorineural hearing loss.

Conclusions:

  • Pseudo-sudden deafness is a potentially reversible SOM-induced phenomenon.
  • Distinguishing feature is preceding otitis media, requiring initial treatment before steroid administration for hearing loss.
