What is the difference between Pars Tensa and pars Flaccida?
The larger of the two zones is the pars tensa. This zone consists of a tough and resilient fibrous layer with a diaphanous mucosal layer inside and squamous epithelium outside. The smaller zone is the pars flaccida, which lies superior to the suspensory ligaments of the malleus and lacks a fibrous layer.
What is Hemotympanum associated with?
Hemotympanum or hematotympanum, refers to the presence of blood in the tympanic cavity of the middle ear. Hemotympanum is often the result of basilar skull fracture. Hemotympanum refers to the presence of blood in the middle ear, which is the area behind the eardrum.
What happens if the tympanic membrane is damaged?
A ruptured eardrum can result in hearing loss. It can also make your middle ear vulnerable to infections. A ruptured eardrum usually heals within a few weeks without treatment. But sometimes it requires a patch or surgical repair to heal.
What is pars tensa?
The pars tensa (plural: partes tensae) is the tense portion of the tympanic membrane and refers to the main portion of the membrane. It extends from the anterior and posterior malleolar folds at the level of the lateral process of malleus to the inferior extent of the tympanic membrane at its attachment.
Where is pars flaccida located?
tympanic membrane
The pars flaccida (plural: partes flaccidae), also known as Shrapnell’s membrane, is the flaccid portion of the tympanic membrane and represents a small portion of the membrane. It lies superior to the anterior and posterior malleolar folds.
Is Myringosclerosis serious?
Surgery for tympanosclerosis usually results in significant improvement of hearing. Damage to the inner ear is a possible and serious complication, which can cause sensorineural deafness.
How is hemotympanum treated?
The treatment of an uncomplicated hemotympanum is usually conservative. Antibiotics may be prescribed for infection prophylaxis. A myringotomy tube may be needed for patients with persistent effusion to prevent long-term complications.
How long does hemotympanum last?
Conclusions. An iTM hemorrhage may develop after blunt head trauma, barotrauma due to scuba diving, or spontaneous epistaxis; otological symptoms included otalgia, tinnitus, and aural fullness. An iTM hemorrhage resolved spontaneously without specific treatment, usually within 1 month.
Can tympanic membrane repair itself?
Most ruptured (perforated) eardrums heal without treatment within a few weeks. Your doctor may prescribe antibiotic drops if there’s evidence of infection. If the tear or hole in your eardrum doesn’t heal by itself, treatment will likely involve procedures to close the tear or hole.
What is a central perforation in the pars tensa?
Information: A central perforation is a perforation in the pars tensa that leaves an intact portion of the tympanic membrane between the rim of the perforation and the bony canal. The fibrous annulus, the tickened portion of the TM near the bony canal, is also intact.
What is a perforation in the tympanic membrane?
A perforation is a hole in the tympanic membrane that is visible through the otoscope. This section contains information on acute traumatic, central, marginal, attic, and total perforations along with information on the monomeric tympanic membrane.
What is the difference between the pars tensa and pars flaccida?
You could also imagine the pars tensa to be similar to a drum surface. It is the portion of the eardrum responsible for translating sound waves into mechanical movement. The pars flaccida, as the name suggests, is less “taut” and also thicker. It drapes across the superior portion of the malleus.
What does a central perforation in the ear look like?
The perforation is dry, no granulation tissue is seen, and the middle ear mucosa is normal. Information: A central perforation is a perforation in the pars tensa that leaves an intact portion of the tympanic membrane between the rim of the perforation and the bony canal.
