The Chondrocutaneous Helical Rim Advancement Flap of Antia and Buch

Abstract

This technique is an excellent method of repairing many defects of the helical rim. Its advantages include technical simplicity, little risk of tip necrosis, patient convenience, and superior cosmesis.

Modified Antia Buch Repair for Full-Thickness Middle Auricular Defect

“…3 Several modifications of this technique have been reported, but these were all upper pole defects. 4 With the addition of a Burrow's triangle, greater advancement of the chondrocutaneous flap is achieved. 5 With the addition of an incision in the helical root and closure as a V-Y advancement, additional length can be obtained for closure of the helical rim.…”

Retroauricular pedicled flap for reconstruction of large helix and antihelix defects

“…More extensive but solely cutaneous defects may be covered with a full‐thickness skin graft, which is usually also able to supply the helix. Short chondrocutaneous defects can be managed with a helical advancement flap , and larger, three‐layer chondrocutaneous defects may be reconstructed using the very well vascularized helical rim advancement flap of Antia and Buch .…”

“…Not uncommonly, however, micrographic surgery of the helix and antihelix results in relatively large two‐layer chondrocutaneous defects for which the aforementioned standard techniques are inadequate. In this setting, the retroauricular pedicled (interpolation) flap is a versatile method for reconstruction . One advantage of this technique not to be underestimated is the preservation of the auricular shape and size.…”

Retroaurikulär gestielte Lappenplastik zur Rekonstruktion großer Ohrhelix‐ und Anthelixdefekte

“…Ausgedehntere, jedoch rein kutane Defekte können mit einem Vollhauttransplantat gedeckt werden, wobei es in der Regel gelingt, auch die Ohrhelix mit zu versorgen. Kurzstreckige Haut‐Knorpel‐Defekte können mit einer Helix‐Verschiebelappenplastik versorgt werden und für größere dreischichtige Haut‐Knorpel‐Defekte kann die sehr gut vaskularisierte Rekonstruktion nach Antia und Buch angewandt werden .…”
