It is indeed quite troublesome for women with obvious appearance of Adam’s apple or those who want a feminized neck. When the thyroid cartilage is shaped in adulthood, even if the transgender hormones are difficult to reshape the cartilage. Therefore, the thyroid cartilage reduction surgery becomes the only option.

Although the wound was mostly hidden at the junction of the chin and neck, the scar was still be widen by the subsequent neck activities. The endoscopic Adam’s apple reduction surgery provide a clear surgical view, invisible surgical scar, and early soft tissue recovery, which will be another alternative.
