Lop & Cup ears
There
is a group of deformities involving the outline of the auricle, and give the
impression of a folded-compressed auricle. The terms "Cup ear”, “Lop ear”,
“constricted ear”, “canoe ear”, “cockleshell ear”, are used to describe
these malformations.

Table Ι
Group | Description |
---|---|
Ι | Helix involved |
ΙΙ | Helix and scapha involved |
ΙΙ Α | No additional skin is needed on the helix |
ΙΙ Β | The ear outline needs additional skin |
ΙΙΙ | Severe folding of the pinna, possible bending forwards; may be accompanied by a stricture in outer ear canal, and in many cases deafness |

Examples according to Tanzer’s grading system - Grades I, IIA, IIB, III
Restoration techniques
The rationale behind a restoration technique is to reveal the skin and reconstruct the auricle’s helix, aiming at height increase.
- Grades Ι and ΙΙΑ do not require additional skin and are considered moderately severe deformities.
- Grade ΙΙΒ requires additional skin, which is taken in the form of a flap from nearby skin.
- Grade ΙΙΙ is considered the most severe and requires major reconstruction.
Grade I moderate deformity restoration
Grade ΙΙΑ deformity restoration
Recovery
Recovery depends on the severity of the damage and the type of restoration. In mild grades, such as I and IIA, recovery resembles that of prominent ears surgery. Grades IIB and III require longer recovery time.
