Mandibular Angle Reduction

Mandibular angle reduction also known as “reduction angleplasty” refers to operations to reduce the width of the lower face and change a square face to an oval. Our comprehensive guide will walk you through everything you need to know about the procedure, from initial consultation to post-operative care.

What is Mandibular Angle Reduction?

A square jaw can be a plus factor for both men and women. In men, it can enhance 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 jawline favor this procedure.

Frequently Asked Questions

Will there be any scars on my face?

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

Will I be in pain?

During surgery, you will be asleep and unable to feel pain. When you awaken from general anesthesia, your doctor will give pain-relief injections or tablets to make you more comfortable. Your face will be sore and swollen in gradually decreasing fashion for two or three weeks. 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.

How long do I have to be in the hospital?

You may be discharged after 2 days. Your doctor will ask you to return for follow up check after within one to two weeks.

What are the possible risks?

Some risks of surgery include bleeding, adverse response to anesthesia, infection, delayed healing, asymmetry, nerve injury with weakness and numbness of the lower lips and jaw, and the need for revision surgery.

How do I prepare for surgery?

To avoid complications and reduce risk factors you need to stop smoking, drinking alcoholic beverages, and taking hormonal pills, herbal supplements, and medicines (other than those that your doctor allows you to continue), at least two weeks before your schedule. People with diseases need surgical clearance from their medical specialists.
