Summary
Persistent secretory otitis media with effusion (SOME) negatively impacts mastoid air cell system (MACS) development. Ventilation tubes in one ear promoted larger MACS development compared to the untreated ear with SOME.
Area of Science:
- Otolaryngology
- Pediatric Otology
- Developmental Biology
Background:
- The development of the mastoid air cell system (MACS) is influenced by various factors, with ongoing debate.
- Secretory otitis media with effusion (SOME) is a common condition in children, particularly those with cleft palate.
Purpose of the Study:
- To investigate the effect of persistent secretory otitis media with effusion (SOME) on the development of the mastoid air cell system (MACS).
Main Methods:
- A prospective study involving 31 four-year-old children with cleft palate.
- One ear per child was ventilated with a tube, while the contralateral ear served as a control with persistent SOME.
- Mastoid pneumatization was measured using planimetry on lateral mastoid X-rays.
Main Results:
- 22 children (44 ears) were analyzed after exclusions.
- The mastoid air cell system was larger in the ventilated ear compared to the ear with persistent SOME in 19 out of 22 children.
- Ventilation tube placement timing varied (3 months vs. 12-16 months).
Conclusions:
- Persistent secretory otitis media with effusion (SOME) appears to hinder mastoid air cell system (MACS) development.
- Middle ear ventilation may promote improved MACS development.

The 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.
The 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...

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...
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.
