Summary
This study details various lesions affecting the external auditory canal (EAC), a crucial part of the ear. High-resolution CT effectively visualizes these congenital, inflammatory, neoplastic, and traumatic conditions within the temporal bone.
Area of Science:
- Otolaryngology
- Medical Imaging
- Anatomy
Background:
- The external auditory canal (EAC) is an S-shaped structure extending from the auricle to the tympanic membrane.
- The EAC is susceptible to various pathologies, including congenital abnormalities, inflammation, tumors, and trauma.
- The temporal bone's complex anatomy necessitates advanced imaging for accurate evaluation.
Purpose of the Study:
- To describe the diverse range of lesions that can affect the external auditory canal.
- To highlight the utility of high-resolution computed tomography (CT) in assessing EAC pathology.
Main Methods:
- Review of imaging studies focusing on the external auditory canal.
- Correlation of imaging findings with clinical data (implied).
- Description of characteristic imaging features for different EAC lesions.
Main Results:
- Identification and categorization of various congenital, inflammatory, neoplastic, and traumatic lesions of the EAC.
- Demonstration of the effectiveness of high-resolution CT in delineating EAC structures and abnormalities.
Conclusions:
- High-resolution CT is a valuable tool for evaluating the external auditory canal and its associated pathologies.
- Comprehensive understanding of EAC lesions is essential for accurate diagnosis and management.

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.

01:13The 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.
01:11The 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...

01:22Hair 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.
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.
