Long Face Syndrome: Symptoms, Diagnosis, and Treatment

5/5 - (1 vote)

Long Face Syndrome, also known as LFS, is a facial condition that affects the proportions and aesthetics of the face. In this comprehensive guide, we’ll delve into the details of Long Face Syndrome, from its definition to its diagnosis and treatment options.

What is Long Face Syndrome?

Long Face Syndrome, also known as LFS, is a facial skeletal disorder that is primarily characterized by an elongated lower third of the face. This condition manifests as a distinct facial disproportion, where the lower part of the face appears significantly longer in relation to the upper facial features. This imbalance in facial proportions can lead to a less harmonious and aesthetically pleasing appearance.

Moreover, beyond the aesthetic concerns, It may also have implications for oral health. The elongation of the lower face can contribute to various dental and orthodontic issues, such as open bites, misaligned teeth, and an increased risk of temporomandibular joint (TMJ) disorders. These oral health challenges can further affect an individual’s overall well-being.


Symptoms of Long Face Syndrome include:

  1. Elongated Lower Face: The most prominent symptom is an extended lower third of the face in comparison to the upper facial features.
  2. Chin Abnormalities: Individuals with LFS may have a pronounced or protruding chin.
  3. Dental Issues: It can lead to dental problems such as misaligned teeth, open bites, and malocclusion (improper alignment of upper and lower teeth).
  4. Temporomandibular Joint (TMJ) Discomfort: Some individuals may experience TMJ pain or dysfunction due to the altered jaw structure.
  5. Aesthetic Concerns: LFS can result in a less balanced and harmonious facial appearance.
  6. Breathing Difficulties: In severe cases, an elongated face may affect the airway, potentially leading to breathing problems during sleep.
  7. Speech Difficulties: The altered facial structure can impact speech articulation in some cases.
  8. Oral Health Complications: Dental decay and gum problems may be more common due to dental misalignment.
  9. Self-Esteem Issues: Aesthetic and functional concerns can lead to reduced self-confidence and self-esteem in affected individuals.
  10. Difficulty Chewing and Eating: Jaw misalignment may make chewing and swallowing food less efficient.

It’s important to note that the severity and combination of these symptoms can vary among individuals with Long Face Syndrome, and treatment approaches may be tailored to address specific issues. Consulting with a healthcare professional is crucial for accurate diagnosis and treatment planning.

How is Long Face Syndrome Diagnosed?

Diagnosing Long Face Syndrome is a meticulous process that requires a comprehensive evaluation conducted by a dental or orthodontic specialist. This evaluation typically encompasses a range of diagnostic measures to thoroughly assess the severity of the condition and plan for appropriate treatment. These diagnostic steps may include:

  1. Clinical Examinations: The specialist will conduct a detailed clinical examination of the patient’s facial structure, jaw alignment, and dental condition. They will carefully observe any abnormalities, such as an elongated lower face or pronounced chin.
  2. X-rays: Dental and craniofacial X-rays are essential for a precise assessment of the skeletal structure. X-rays can reveal the exact dimensions of the face, jaw, and teeth, helping to confirm the diagnosis.
  3. Facial Measurements: Precise measurements of the face, including the length of the lower third of the face, can be taken to determine the extent of the elongation characteristic of LFS.

As for the causes of Face Syndrome, they can be multifactorial and complex. While there may not always be a single, definitive cause, several contributing factors are often considered, including:

  • Genetic Factors: Genetics can play a role in the development. A family history of the condition may increase the likelihood of its occurrence.
  • Growth Patterns: Abnormal growth patterns of the facial bones and jaw during childhood and adolescence can contribute to Long Face Syndrome.
  • Oral Habits: Prolonged thumb-sucking, tongue thrusting, or other oral habits during childhood may influence the development of the facial structure.

It’s important to emphasize that Long Face Syndrome is a condition that can have multiple contributing factors, and the specific causes can vary from person to person. A thorough evaluation by a specialist is essential to determine the underlying factors and develop an effective treatment plan tailored to the individual’s needs.

What to Expect During Surgery to Correct Long Face Syndrome?

Surgical correction of LFS is a complex procedure that aims to restructure the facial skeleton. Patients can expect a thorough evaluation, pre-surgical planning, and post-operative recovery. The surgery typically involves repositioning the jaw and/or chin to achieve facial harmony.


  1. What is Long Face Syndrome?
    • LFS is a facial skeletal disorder characterized by an elongated lower third of the face, resulting in a less balanced facial appearance.
  2. Is Long Face Syndrome a common condition?
    • LFS is relatively rare compared to other facial skeletal conditions but can affect individuals of all ages.
  3. What are the symptoms of Long Face Syndrome?
    • Common symptoms include an extended lower face, pronounced chin, dental misalignment, and a less harmonious facial profile.
  4. How is LFS diagnosed?
    • Diagnosis typically involves a comprehensive evaluation by a dental or orthodontic specialist, including clinical examinations, X-rays, and facial measurements.
  5. What causes LFS?
    • The exact cause can vary but is often attributed to genetic factors, growth patterns, or habits like thumb-sucking during childhood.
  6. Is Long Face Syndrome treatable?
    • Yes, LFS is treatable, and treatment options may include orthodontic procedures, orthognathic surgery, or a combination of both, depending on the severity.
  7. At what age is it best to seek treatment for Long Face Syndrome?
    • Early detection and treatment planning are crucial. Children and teenagers may benefit from intervention to guide facial growth and prevent more severe issues in adulthood.
  8. What are the treatment options for Long Face Syndrome?
    • Treatment options can include orthodontic braces, orthognathic surgery to reposition the jaw, or a combination of these approaches tailored to the individual’s needs.
  9. Is Long Face Syndrome surgery invasive?
    • If recommended, oral and maxillofacial surgeons perform orthognathic surgery, which is considered safe. Advances in surgical techniques have reduced invasiveness and recovery time.

  10. Does Long Face Syndrome treatment improve oral health?
    • Yes, treatment can help improve oral health by addressing issues like misaligned teeth, bite problems, and speech difficulties associated with LFS.


Long Face Syndrome can significantly impact facial aesthetics and oral health. Fortunately, with advancements in dentofacial orthopaedics and surgical techniques, effective treatments are available. If you or a loved one are dealing with LFS, consult with a qualified specialist to explore the best treatment options for achieving facial balance and a confident smile.
