What is a Tragal cartilage graft?
A cut through the skin and cartilage is made on the medial side of the tragus, leaving 2 mm of cartilage in the dome of the tragus for cosmesis. The tragal cartilage is harvested together with the perichondrium.
What is a tympanoplasty with a cartilage graft?
Introduction. Tympanoplasty is a procedure done to repair tympanic membrane and middle ear sound conducting mechanism. Graft materials like temporalis fascia, vein graft, fascia lata and perichondrium are used to seal the perforations .
What is Transcanal tympanoplasty?
Objective. Transcanal endoscopic type 1 tympanoplasty is a minimally invasive procedure that enables better visualization of deep and narrow spaces compared to conventional microscopic methods.
Where is graft taken from for tympanoplasty?
In tympanoplasty, the surgeon will take a small piece of tissue from under the skin behind or above your child’s ear. This tissue is very much like eardrum tissue, and the surgeon will graft it across the eardrum hole. The graft encourages the normal eardrum tissue to grow across the hole.
How is tympanoplasty performed?
A tympanoplasty is performed with the patient fully asleep (under general anesthesia). A surgical cut (incision) is usually made behind the ear, the ear is moved forward, and the eardrum is then carefully exposed. The eardrum is then lifted up (tympanotomy) so that the inside of the ear (middle ear) can be examined.
What is the success rate of tympanoplasty?
In previous studies, success rates for inlay tympanoplasty have ranged from 68% to 100%. The present study showed an overall success rate of 87%, which is acceptable compared with that of underlay tympanoplasty.
Will tympanoplasty improve my hearing?
Tympanoplasty is an effective procedure that can lead to improvement in hearing function of patients and prevention of recurrent ear discharge. Optimal results can be achieved by the use of the appropriate surgical technique.
How long does a Ossiculoplasty take?
The procedure for ossiculoplasty takes place under general anesthesia and takes approximately one to two hours. This is done either by itself or in conjunction with other procedures including mastoidectomy and ossicular chain reconstruction. An incision is made behind the ear to access the ear canal.
Is tragal cartilage shield tympanoplasty a reliable technique?
This study reveals that tragal cartilage shield tympanoplasty is a reliable technique, in fact it has a high degree of graft take and hearing results are satisfactory.
What is cartilage-perichondrial composite graft tympanoplasty?
Cartilage-perichondrial composite graft tympanoplasty in the treatment of posterior marginal and attic retraction pockets. Laryngoscope 1987;97:1069-74. [PubMed] [Google Scholar] 19. Eviatar A. Tragal perichondrium and cartilage in reconstructive ear surgery.
What size cartilage is used for tympanic membrane reconstruction?
This cartilage is ideal since it is thin, flat and in sufficient quantities to permit reconstruction of the entire tympanic membrane. Typically, the piece of cartilage is 15 mm in length and 10 mm in width in children and somewhat larger in adults.
Why is tragal cartilage used as a full thickness graft?
The thickness of the cartilage creates stiffness that is more resistant than the fascia to the anatomic deformation caused by negative middle ear pressure, thus improving long-term integrity. The tragal cartilage is typically slightly less than 1 mm thick and therefore is used as a full-thickness graft.
