What causes protruding jaw and brow and what should I do?

Symptom Database

Protruding jaw and brow are common facial features that can affect a person’s appearance and self-confidence. While some individuals may embrace these features as unique characteristics, others may feel self-conscious and seek ways to address them. In this article, we will explore the causes of protruding jaw and brow, the available treatment options, and what individuals can do to improve their facial aesthetics.

Understanding Protruding Jaw and Brow

Protruding jaw refers to a condition where the lower jaw extends forward, creating an imbalance in facial symmetry. This can result in a prominent chin and a less defined jawline. On the other hand, protruding brow refers to a condition where the upper part of the forehead juts out, giving the face a more pronounced appearance.

Causes of Protruding Jaw and Brow

Protruding jaw and brow can be caused by a variety of factors, including:

  • Genetics: Facial bone structure is largely determined by genetics. If your parents or close relatives have a protruding jaw or brow, you may be more likely to develop these features.
  • Malocclusion: Misalignment of the teeth and jaws, known as malocclusion, can contribute to a protruding jaw. This can be caused by factors such as thumb sucking, tongue thrusting, or an improper bite.
  • Overgrowth of facial bones: In some cases, the bones in the jaw and brow region may grow excessively, leading to a protruding appearance.
  • Facial trauma: Injuries to the face, such as fractures or dislocations, can alter the shape and structure of the jaw and brow.

Treatment Options for Protruding Jaw and Brow

Fortunately, there are several treatment options available for individuals seeking to address protruding jaw and brow:

Jaw and Brow Surgery

Jaw and brow surgery, also known as facial bone surgery or maxillofacial surgery, is a common approach to correcting protruding features. This procedure involves reshaping the bones in the jaw and brow region to achieve a more balanced and harmonious facial contour. It is typically performed by a skilled oral and maxillofacial surgeon.

Orthognathic Surgery

Orthognathic surgery is a specialized form of jaw surgery that focuses on correcting skeletal and dental irregularities. It can be used to address both functional issues, such as difficulty chewing or speaking, as well as aesthetic concerns, including a protruding jaw. This procedure involves repositioning the jawbones to improve facial symmetry and restore proper alignment.

Improving Facial Aesthetics and Symmetry

In addition to surgical interventions, there are non-surgical approaches that can help improve facial aesthetics and symmetry:

Facial Contouring

Facial contouring refers to a range of non-invasive or minimally invasive procedures aimed at enhancing the shape and structure of the face. This can include techniques such as dermal fillers, which can be used to add volume and definition to specific areas, or Botox injections, which can help relax muscles and reduce the appearance of wrinkles.

Facial Reconstruction

In cases where the protruding jaw or brow is a result of facial trauma or deformities, facial reconstruction may be necessary. This can involve a combination of surgical procedures to repair and restore the affected areas, improving both function and aesthetics.


Protruding jaw and brow can have a significant impact on a person’s facial aesthetics and self-esteem. Understanding the causes of these features and the available treatment options is essential for individuals seeking to address them. Whether through surgical interventions or non-surgical approaches, there are various ways to improve facial symmetry and achieve a more balanced and harmonious appearance. Consulting with a qualified healthcare professional is crucial to determine the most suitable treatment plan based on individual needs and goals.
