What Are Drooping Mouth Corners?

Drooping mouth corners are a physical condition involving changes in the shape and position of the corners of the mouth, often making the face look sad or tired. The change can stem from several causes, including deterioration of the muscles around the mouth, nerve abnormalities, or injury. The condition can affect facial expression and the ability to convey emotion, which may in turn impact social interaction and self-confidence.

Causes of Drooping Mouth Corners

Drooping mouth corners can result from several factors:

• Nervous system: neurological disorders or damage to the nerves controlling the muscles around the mouth can cause the corners to sag. This can occur due to paralysis, partial paralysis, or diseases affecting the nervous system such as Parkinson's disease
• Bone structure: changes in the bone structure of the jaw or face — for example from tooth loss — can affect the support of the facial skin and muscles, causing the mouth corners to drop
• Muscle deterioration: advancing age can lead to loss of muscle and skin elasticity, weakening the muscles around the mouth and causing the corners to droop

Diagnosis and Treatment

Diagnosis usually begins with a physical examination by an aesthetic medicine specialist or dermatologist, which may include assessing muscle function and nerve testing. Treatment options depend on the cause and severity of the condition, and may include:

• Botox injections: injected to relax the muscles at the corners of the mouth, helping lift the corners back to their normal position
• Filler injections: dermal filler adds volume beneath the skin and lifts the corners of the mouth
• Surgery: in severe cases, or when other treatments fail, surgery can reposition the muscles and skin to restore the desired shape

Managing drooping mouth corners effectively requires careful assessment and a treatment plan matched to each individual's specific cause. The right treatment can restore a bright smile and a more youthful look.

How to Correct Drooping Mouth Corners

Correcting drooping mouth corners requires careful consideration to achieve natural-looking, long-lasting results. Several methods can help, each with its own pros and cons. Here are the main treatment options available:

1. Botulinum Toxin (Botox) Injections

Botox is one of the most popular corrections for drooping mouth corners. The injection relaxes the muscles that pull the corners downward, allowing them to lift and creating a livelier, brighter appearance. Results typically last around 3-4 months before a repeat injection is needed.

2. Dermal Fillers

Fillers are another popular way to lift sagging mouth corners. Injected filler adds volume beneath the skin at the corners of the mouth, making them look lifted and reducing the drooping or sagging appearance. There are many types of filler, some lasting up to a year or more.

3. Surgical Options

For those with severely drooping mouth corners who want permanent results, surgery may be the right choice. Corner-of-mouth surgery — known as a "lip corner lift" — can adjust the structure and position of the muscles around the mouth so the corners sit lifted in the desired position.

4. Facial Exercises

Although the results are not as pronounced as other treatments, facial muscle exercises may strengthen the muscles responsible for lifting the mouth corners and improve muscle endurance in the area.

The right treatment depends on your doctor's recommendation after assessing the nature and severity of the drooping, taking each patient's expectations and needs into account to achieve the best result.

What Causes a One-Sided Drooping Mouth Corner?

A drooping corner on one side of the mouth can arise from several medical or physical factors affecting the facial muscles and nerves. It makes the face look asymmetrical and can affect facial expression and speech. These are the main causes of a one-sided drooping mouth corner.

1. Nerve Abnormalities

• Bell's palsy: the most common cause of a one-sided drooping mouth corner, caused by inflammation or damage to the facial nerve that temporarily weakens or paralyses part of the facial muscles
• Tumours or nerve injury: a tumour or injury affecting the nerves that control the facial muscles can also cause this problem

2. Other Medical Conditions

• Diseases affecting the nervous system: conditions such as Parkinson's disease, stroke, or multiple sclerosis can cause drooping mouth corners because they affect the muscles and nerves

3. Facial Injury

• Accident-related injury: trauma to the face from an accident can damage the muscles or nerves that control mouth movement

Treating a One-Sided Drooping Mouth Corner

Treatment for a one-sided drooping mouth corner depends on the cause. Options may include:

• Medication: for cases such as Bell's palsy, steroids or antivirals may be used to reduce inflammation and speed recovery
• Botox or filler injections: to rebalance the mouth corners and reduce asymmetry
• Surgery: where nerve damage is severe, surgery may be needed to repair the nerve or restore function
• Physical therapy: for mild cases, facial exercises may help strengthen the muscles and improve muscle control in the face

Seeing a doctor for an accurate diagnosis is essential to identify the cause and choose the right treatment for a one-sided drooping mouth corner.

Summary

Drooping mouth corners can affect facial expression and confidence, but with today's wide range of treatments and advances in aesthetic medicine, there are many ways to manage and correct the problem. Consulting an aesthetic medicine specialist or dermatologist will get you the advice and treatment best suited to your condition.
