Converse oturgery

The otoplasty surgery after Converse is a conventional or traditional method of Otopexie . It is the most commonly used otoplasty operation among traditional methods.

history

Converse described his method in 1955 and 1963.

Surgical method

It is an anti-helix plastic that is performed using the incision suture technique .

method

A long incision is made on the back of the auricle and a strip of skin is removed. The cartilage is completely severed in several places. If the cartilage is thick, it is thinned on the back of the anthelix by removing cartilage flat with a knife. In the case of a large cavum conchae (depression in front of the auditory canal entrance ), a crescent-shaped piece of cartilage is also removed from the concha to reduce it. Or a so-called concharotation is performed, in which first muscle and connective tissue is removed from the posterior sulcus (region of the attachment of the auricle to the head) and then the ear with sutures that run between the periosteum of the skull and the conchal cartilage towards the head rotated and so its distance is reduced. With several mattress sutures that are anchored in the cartilage, a new antihelical fold is formed or a weakly developed antihelical fold is bent more strongly. After inserting a drainage tube for 1 or 2 days, the skin wound on the back of the auricle is sutured. Sometimes the newly formed anthelix is also fixed with external mattress sutures that are tied over small swabs so that they do not cut into the skin. A bandage is usually applied for 1 to 2 weeks.

The Converse procedure, together with Mustardé and Stenström's otoplasty operations, is one of the standard methods of traditional oturgery. Numerous variants of the ear attachment were derived from them.

Risks and possible complications

According to Weerda: deformations of the auricle up to deformations in all levels due to cartilage destruction (so-called “catastrophic ear” according to Staindl) too tightly fitting ear; Telephone earpiece and inverted telephone earpiece; visible, cosmetically disfiguring cartilage and skin retraction along the edges and in the Anthelixvorderfläche concha cavum ; Infection with abscess or inflammation of the cartilage ( perichondritis ); Thread fistula ; Thread repulsion; Granuloma ; Atheroma ; Bleeding; Hematoma , relapse (ears stick out again); too tight ear, hypertrophic scar or keloid along the skin incision, hypersensitivity and pain to pressure and cold; Tissue destruction Necrosis from pressure if the bandage is too tight and hard; Narrowing of the ear canal opening; Greater asymmetry of the ear distances (see also chapter Otopexy )
