Summary
This case study highlights a young man with enlarged auditory canals who experienced sudden sensorineural hearing loss after weight-lifting. This suggests a potential link between strenuous exercise and hearing loss in susceptible individuals.
Area of Science:
- Otolaryngology
- Neurology
Background:
- Bilateral enlarged internal auditory canals (IACs) are a rare anatomical variation.
- Sudden sensorineural hearing loss (SSNHL) can have various triggers, but exercise-induced cases are uncommon.
Observation:
- A young male patient presented with bilateral enlarged IACs.
- He experienced sudden, profound left-sided hearing loss immediately after weight-lifting exercise.
- A second episode of sudden hearing loss occurred during subsequent weight-lifting, despite medical treatment.
Findings:
- High-resolution computed tomography (HRCT) and magnetic resonance imaging (MRI) confirmed bilateral enlarged IACs.
- The patient's hearing loss was sudden onset and sensorineural.
- The hearing loss recurred with similar physical exertion.
Implications:
- This is the first reported case of bilateral SSNHL associated with weight-lifting in a patient with patulous IACs.
- Physicians should consider exercise as a potential trigger for hearing loss in patients with enlarged IACs.
- Patients with this condition may benefit from lifestyle warnings regarding strenuous physical activity.

01:16Anatomy 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...
01:15Auditory 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.

01:31Hearing
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.
01:11The Auditory Ossicles
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

01:13The Cochlea
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.
01:22Hair Cells
Hair cells are the sensory receptors of the auditory system—they transduce mechanical sound waves into electrical energy that the nervous system can understand. Hair cells are located in the organ of Corti within the cochlea of the inner ear, between the basilar and tectorial membranes. The actual sensory receptors are called inner hair cells. The outer hair cells serve other functions, such as sound amplification in the cochlea, and are not discussed in detail here.
