Mandibular Angle Reduction

Mandibular angle reduction also known “reduction angleplasty” refer to operations to reduce the width of the lower face and change a square face to an oval.

What is Mandibular Angle Reduction?

A square jaw can be a plus factor for both men and women. In men, it can enhance the masculine features, while in women it can give an impression of strength and confidence.  In some, however, the jaw can be disproportionately wide as compared to the rest of the face. This is one reason for aesthetic mandible angle reduction. People who wish to soften their face with a more feminine jaw-line favor this procedure.

Q1: Will there be any scars on my face?

Many patients prefer the intra-oral approach because this technique shows no scars after surgery.

During this time, there will be a limitation of face and mouth movement so will need a soft diet until the incisions in your mouth heal.
