Summary
Most microtia reconstruction patients achieve good protective skin sensitivity. However, the helix area showed poor results in some patients, indicating a need for further attention in ear reconstruction outcomes.
Area of Science:
- Plastic Surgery
- Reconstructive Surgery
- Otolaryngology
Background:
- Aesthetic outcomes are not the sole measure of success in microtia ear reconstruction.
- Protective skin sensitivity is crucial for preventing damage to the reconstructed ear's framework.
Purpose of the Study:
- To evaluate protective skin sensitivity in patients who underwent microtia ear reconstruction.
- To identify specific areas of the reconstructed ear that may have compromised sensitivity.
Main Methods:
- A cohort of 39 patients with unilateral microtia was studied.
- The Semmes-Weinstein Monofilament Test (SWMT) assessed protective sensitivity thresholds.
- Sensitivity was measured in the helix, anthelix, and lobule, with the contralateral ear serving as a control.
Main Results:
- Thirty-two out of 39 patients demonstrated acceptable protective sensitivity across the entire reconstructed ear.
- Seven patients exhibited poor sensitivity in the helix region.
- One patient also showed poor sensitivity in the anthelix area.
Conclusions:
- Microtia ear reconstruction generally yields good protective skin sensitivity.
- The helix and anthelix regions may require specific focus to ensure adequate protective sensation post-surgery.

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...
01:21Sensation
Sensory receptors are specialized neurons that respond to specific types of external stimuli, initiating the process known as sensation. This occurs when sensory input, such as light entering the eye, is detected by these receptors, causing chemical changes in the cells of the retina. These cells then convert the sensory stimulus into action potentials that are transmitted to the central nervous system, a process termed transduction.

00:53Sound Intensity Level
Humans perceive sound by hearing. The human ear helps sound waves reach the brain, which then interprets the waves and creates the perception of hearing. The loudness of the environment in which a person is located determines whether they can distinguish between different sound sources.
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and hence a...

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.
01:13The 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.
