Aural syringing:
This procedure helps in
1. Removal of wax from the ear
2. Clean up the external auditory canal fungus
3. To remove non hygroscopic ear foreign bodies
The capacity of aural syringe is about 120 ml or 4 ounces. Aural sryinges are commonly manufactured as metal syringes which can be sterilized and reused. Plastic disposable aural syringes are also available.
This small retractor is used in mastoid surgeries commonly.
It has three prongs of uniform size.
The retractor can be applied by turning the thrumb screw.
When used in combination with Mollison's retractor it improves exposure during mastoid surgeries.
Uses:
1. Used in harvesting temporalis fascia graft
2. Used in mastoidectomy along with Mollison's retractor providing the best exposure
3. Can be used in thyroid surgeries to retract soft tissues in the neck
This retractor has three prongs of equal sizes in one blade and a single flat broad prong on the other blade.
The single flat broad prong is useful in retracting skin away from the surgical site.
It is very useful in retracting canal skin during ear surgeries.

This retractor was designed by Franz Weitlaner of Austria who was famous for designing instruments.
It has three prongs on one side and four on the other.
All these prongs are sharp in nature.
The prongs and teeth are of uniform size.
This retractor is smaller than Mollison's retractor.
Length is about 8 inches
It is used in:
1. Pediatric mastoid surgeries
2. Useful to retract soft tissues in Plastic and Orthopaedic surgical procedures
This retractor is smaller in size when compared to that of mollison retractor.
Middle teeth of one prong is slightly longer. This can be used to retract external canal wall skin for better visualization.
1. Used in mastoid surgeries to visualize the external canal and middle ear cavity
2. Can be used in endaural surgeries (mastoidectomy) is classic end aural retractor is not available
3. The pressure applied by the prongs to the soft tissue keeps the operating field dry because of its hemostatic effect
This self retaining retractor is used commonly in mastoid surgeries.
1. To Harvest temporalis fascia graft
2. To expose the mastoid cortex and hold the soft tissue apart
3. In difficult neck surgical procedures where two hands need to be free
4. In surgeries involving the skull

Synonyms:
Myringoplasty, Tympanoplasty.
Definition:
Myringoplasty is a procedure used to seal a perforated tympanic membrane using a graft material.
Temporalis fascia is the commonly used graft material because:
1. It is an autograft with excellent chance of take
2. It is available close to the site of operation making its harvest easier
3. It has a low basal metabolic rate, brightening its success rate
4. Its thickness is more or less similar to that of tympanic membrane
This surgical procedure is performed to treat deafness due to otosclerosis. Otosclerosis is caused by fixation of the foot plate of stapes which prevents efficient sound transmission to the oval window. The deafness caused is conductive in nature.
The surgical procedure is performed under local anesthesia. Advantages of performing this surgery under local anesthesia are:
1. Improvement in hearing can be ascertained on the table.
2. Bleeding is minimal under local anesthesia.
