What grafts is used for tympanoplasty?

What grafts is used for tympanoplasty?

The fascia temporalis is the most commonly used graft, with success rates between 93% and 97% in primary tympanoplasty, especially in well-aerated middle ears.

What are the five types of tympanoplasty?

Wullstein Classification:

• Type I: repair of the TM alone; no abnormality of the middle ear.
• Type II: repair of the TM and middle ear; the malleus is eroded.
• Type III: repair of the TM onto the stapes head; the malleus and incus have a defect.
• Type IV: the TM is grafted to the stapes footplate, which is movable.

What is Type 4 tympanoplasty?

In a type IV tympanoplasty, the stapes footplate is directly exposed to incoming sound while the round window is “shielded,” usually with a fascia graft. Postoperative hearing results are quite variable, with air-bone gaps ranging from 10 to 60 dB.

What is a Type 3 tympanoplasty?

Background: Type III stapes columella tympanoplasty involves the placement of a tympanic membrane graft, usually made of temporalis fascia, directly onto the stapes head. The procedure is usually done in conjunction with a canal wall down mastoidectomy.

What are the types of mastoidectomy?

Broadly, there are two major types of mastoidectomy: canal wall up and canal wall down. [1] Canal wall up mastoidectomy preserves the posterior bony external auditory canal, which separates the ear canal from the mastoid cavity.

How many types of tympanoplasty are there?

Tympanoplasty is classified into five different types, originally described by Horst Ludwig Wullstein (1906–1987) in 1956. Type 1 involves repair of the tympanic membrane alone, when the middle ear is normal. A type 1 tympanoplasty is synonymous to myringoplasty.

What is a Type II tympanoplasty?

Type 2 involves repair of the tympanic membrane and middle ear in spite of slight defects in the middle ear ossicles. Type 3 involves removal of ossicles and epitympanum when there are large defects of the malleus and incus. The tympanic membrane is repaired and directly connected to the head of the stapes.

What is a Type 1 tympanoplasty?

Type 1 tympanoplasty is a procedure performed to repair tympanic membrane perforations, primarily to reduce otorrhoea. This may subsequently lead to improvement of hearing. The common graft materials used are temporalis fascia and cartilage from tragus or concha.

What is Myringostapediopexy?

[ mə-rĭng′gō-stā-pē′dē-ə-pĕk′sē ] n. Tympanoplasty in which the tympanic membrane is functionally connected with the stapes.

What are the three types of mastoidectomy?

Types of mastoidectomy

• Simple mastoidectomy. The lateral wall of the mastoid is removed.
• Canal wall up (closed) mastoidectomy. See the separate article: canal wall up mastoidectomy.
• Canal wall down (open) mastoidectomy.
