Meniere's disease and the mastoid pneumatization
Acta Oto-Laryngologica
|January 1, 1980
Summary
Mastoid pneumatization size did not differ between Meniere's disease patients, those with sensorineural hearing loss, and healthy individuals. This study examined radiographic mastoid air cell development in these groups.
Area of Science:
- Otolaryngology
- Radiology
- Neurosurgery
Background:
- Mastoid pneumatization, the development of air cells in the mastoid bone, is a complex process.
- Variations in mastoid pneumatization have been anecdotally linked to various ear conditions.
- Understanding these variations may offer insights into underlying pathophysiology.
Purpose of the Study:
- To quantitatively assess and compare mastoid pneumatization size across different audiological groups.
- To investigate potential correlations between Meniere's disease and mastoid air cell volume.
- To explore the relationship between sensorineural hearing loss and mastoid pneumatization.
Main Methods:
- Radiographic examination using Law projection for mastoid imaging.
- Planimetric measurement of mastoid pneumatization.
- Comparison of measurements among three patient cohorts: Meniere's disease, other sensorineural hearing loss, and healthy controls.
Main Results:
- No statistically significant differences were observed in mastoid pneumatization size among the three groups.
- Radiographic and planimetric analyses did not reveal a distinct pattern related to Meniere's disease.
- Mastoid air cell volume appears independent of the presence of sensorineural hearing loss in this cohort.
Conclusions:
- Mastoid pneumatization size is not a differentiating factor for Meniere's disease or sensorineural hearing loss.
- The study discusses Meniere's disease and factors potentially influencing mastoid pneumatization.
- Further research is warranted to explore other potential anatomical or etiological factors in Meniere's disease.

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.
01:29The Vestibular System
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.
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...
01:15Equilibrium and Balance
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...
01:17Auditory Perception
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the cochlea, a...
01:26Bacterial Meningitis II: Pathophysiology
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
