What is fenestration operation?

In 1913, Jenkins (6) first described an innovative type of surgery, which he called fenestration. This surgery consisted of the creation of a window in the vestibule or in the lateral semicircular canal, allowing the transmission of sound waves from the middle ear to the perilymph.

What is the difference between stapedectomy and stapedotomy?

Compared to a stapedectomy, a stapedotomy includes the use of a laser to make a precise hole (fenestration) in the stapes footplate. While a stapedectomy typically removes the entire stapes footplate and has it replaced with a micro prosthesis.

How does a stapedectomy work?

In stapedectomy, the doctor uses a microscope to see the small bones of the inner ear. Entering through the natural opening in your ear, your doctor makes an incision, moves your eardrum out of the way, and separates the stapes from the incus bone before removing the stapes.

What does fenestration mean in medical terms?

Medical Definition of fenestration 1a : a natural or surgically created opening in a surface. b : the presence of such openings. 2 : a surgical procedure that involves cutting an opening in the bony labyrinth between the inner ear and tympanum to replace natural fenestrae that are not functional (as in otosclerosis)

What material is used in a stapedectomy?

The materials evolved from Teflon, metal, to plastic, and most recently to gold and titanium. While initially the diameter of the pistons used was 0.8 and 0.6 mm, from the 1970s onwards, it has been becoming even smaller in order to ease the procedure and reduce the risk of inner ear damage.

Why does a fenestration occur?

A naturally occurring fenestration leaves the exposed root surface in direct contact with either the alveolar mucosa or the gingiva. The condition may be caused by a variety of factors including tooth movement due to orthodontics, pathology (both endodontic and periodontal), root apex contours, and occlusal issues.

What causes fenestration?

Can you get an MRI if you have a stapedectomy?

Any patient who had a stapedectomy between 1987 and 1989 should not have an MRI scan.] Maxum™ Hearing Implant: If you have had a Maxum™ Hearing Implant, you should not have any type of magnetic resonance imaging (MRI) study. The Maxum™ Hearing Implant is not MRI compatible.

What is the difference between fenestration and dehiscence?

Dehiscence is the incomplete coverage by bone over an area of a root that includes the cemento-enamel junction. Whereas fenestration is a window of bone loss which exposes the root surface to the gingival or alveolar mucosa.

What is fenestration surgery for otosclerosis?

As you know, otosclerosis is a disorder that results in conductive hearing loss due to progressive thickening of the stapes footplate. In the 1940s and 1950s surgeons performed the fenestration operation, which was successful in restoring some of the conductive hearing loss. In this procedure, a canal wall down mastoidectomy is performed.

What is the fenestration operation?

In the 1940s and 1950s surgeons performed the fenestration operation, which was successful in restoring some of the conductive hearing loss. In this procedure, a canal wall down mastoidectomy is performed.

What is the history of stapedial surgery for fenestral otosclerosis?

Early attempts to correct the conductive hearing loss associated with fenestral otosclerosis date to the late 19th century. The first stapedial operations were performed in 1875 by Kessel (1), who attempted stapedial mobilization. Boucheron (2) reported 60 stapes mobilizations in 1888, and Miot (3) reported 200 such procedures.

What is a fenestration of the lateral semi circular canal?

A fenestration is made in the outer portion of the lateral semi-circular canal, preserving the end osteo layer. A fascia graft was then placed over this fenestration and the cavity was allowed to heal.
