The temporalis muscle is one of the muscles used for chewing, and it can become enlarged due to various reasons, including increased masticatory muscle activity and morphologic changes in the temporal bone. While there is no guaranteed way to shrink the muscle, some people may turn to Botox injections to reduce its size. However, it is important to note that this procedure is typically recommended for individuals experiencing discomfort or tension in that area and should only be performed by a knowledgeable injector to avoid side effects.

What You'll Learn

Botox injections can be used to shrink the temporalis muscle
Botox injections for shrinking the temporalis muscle are considered a simple procedure if administered by someone knowledgeable and experienced. It is recommended to seek out a board-certified plastic surgeon or a trained clinician who performs their own injections. The exact dosage and location of the Botox injections will vary depending on individual needs. Side effects are rare when administered by an experienced injector.
When used to treat TMJ, Botox injections are typically administered into the masseter and temporalis muscles, which are responsible for closing the jaw from an open position. Botox may also be injected into the lateral pterygoid muscles, which control the movement of the jaw side-to-side and the opening of the mouth. It is important to note that Botox injections do not help with symptoms such as jaw locking or clicking, which are usually caused by loose ligaments and changes in the position of the shock-absorbing disc.
The effects of Botox injections for shrinking the temporalis muscle can last up to 4 months, and repeat injections may be required every 3 to 6 months to maintain the desired results. The full effects of the treatment may take a few months to become apparent. Botox injections in this area can also be coupled with injections into the masseters to relieve symptoms of TMJ.

Seek a board-certified plastic surgeon for the procedure
If you are considering undergoing a procedure to shrink your temporalis muscle, it is important to seek a board-certified plastic surgeon. The temporalis muscle is a chewing muscle located on the side of the temple and extending to the jaw, which helps with jaw closure. There are several techniques for performing temporalis muscle surgery, and a board-certified plastic surgeon will be able to advise on the best approach for your specific needs and goals.
One such technique is the lengthening temporalis myoplasty, popularized by French surgeon Daniel Labbé. This technique involves disconnecting the muscle from its origin in the skull and insertion in the mandible, and then advancing it toward the mouth. When properly placed, the muscle is secured in its new position, helping to recreate a smile. This approach is particularly suitable for patients with long-standing facial paralysis, where the facial muscles have atrophied.
Another option is the temporalis muscle flap, a local muscle flap technique where the muscle is disconnected from its attachments but remains connected to its blood and nerve supply. It is then reattached in a new position without the need for vessel and nerve reattachment. This procedure can help restore function, appearance, and balance in patients with facial palsy.
When considering a board-certified plastic surgeon for your procedure, it is essential to research their qualifications, experience, and expertise in performing temporalis muscle surgery specifically. You may also want to schedule consultations with multiple surgeons to discuss your goals, understand their recommended approach, and assess your comfort and confidence in their care.
During your consultations, be sure to ask about the potential risks and complications associated with the procedure. While the specific risks will depend on the exact nature of the surgery, general risks of facial surgery include bleeding, bruising, infection, injury to the nerves at the donor sites, temple hollowing, scarring, numbness, and the need for additional surgery. It is also important to discuss anesthesia options, as some procedures may require general anesthesia, while others can be performed under local anesthesia or conscious sedation.

Side effects are rare but can occur
While side effects from Botox injections in the temporalis muscle are rare, they can still occur. It is important to be aware of these potential risks before undergoing treatment. One possible side effect is a temporary headache, which can be mild or moderate in intensity. Some individuals may also experience temporary bruising or redness at the injection site, which typically resolves within a few days.
In rare cases, more serious side effects can occur, such as drooping eyelids or cockeyed eyebrows. These side effects are usually temporary and can last for a few weeks. It is crucial to select a qualified and experienced injector to minimise the risk of adverse events. An experienced injector will be knowledgeable about the appropriate dosage and injection sites, reducing the likelihood of side effects.
Additionally, it is important to be aware of potential allergic reactions to the Botox solution. While rare, some individuals may experience mild allergic responses, such as skin rash or itching. In extremely rare cases, a severe allergic reaction known as anaphylaxis can occur, which requires immediate medical attention.
Moreover, some individuals may be more susceptible to side effects than others. For example, people with underlying medical conditions or those taking certain medications may have an increased risk of adverse events. It is always advisable to consult with a healthcare professional before undergoing any cosmetic procedure to ensure that it is safe and appropriate for your individual circumstances.
Although side effects are uncommon, it is essential to be well-informed and to select a qualified and experienced injector to minimise potential risks and ensure a safe treatment experience.

Results may take a few months to appear
Results from Botox injections to reduce the size of the temporalis muscles may take a few months to appear. Botox injections in this area are typically only recommended for individuals experiencing discomfort or tension in the temporalis region. The injections are usually coupled with Botox in the masseters to relieve symptoms of TMJ.
It is important to note that the number of injections needed to see results varies from person to person. Some individuals may require repeated injections at 3 to 6-month intervals to maintain the desired effect. The exact dosage and location of the Botox injections will depend on the individual's specific needs.
To ensure optimal results and minimize side effects, it is recommended to seek out an experienced injector, such as a board-certified plastic surgeon or a doctor who has performed a significant number of temporalis muscle injections. Asking about their experience and the number of injections they have administered in this area can provide valuable insight into their expertise.
While Botox injections can effectively reduce the size of the temporalis muscles, it is important to keep in mind that the results may not be immediate and that multiple injections may be necessary to achieve and maintain the desired outcome. Additionally, Botox is not the only treatment option for reducing muscle size, and other medical procedures or therapeutic approaches may be explored based on individual needs and preferences.

Repeated injections may be required to maintain results
While it is possible to reduce the size of the temporalis muscles with Botox injections, repeated injections may be required to maintain results. Botox injections in the temporalis muscles are typically recommended for individuals experiencing discomfort or tension in that area. The injections can help alleviate symptoms of TMJ and are often coupled with Botox in the masseters.
The frequency of repeated injections can vary, with some sources suggesting intervals of 3 to 6 months, while others recommend injections every 4 to 6 months. The specific interval may depend on individual factors, such as the severity of the condition and the desired results. It is important to consult with a qualified and experienced healthcare professional to determine the appropriate treatment plan.
The effectiveness of Botox injections in shrinking the temporalis muscles is supported by the expertise of medical professionals. Dr. Vincent D. Lepore, a retired MD, affirms that Botox injections can successfully reduce the size of the temporalis muscles. Similarly, Dr. ALDO advises that Botox will lead to atrophy, or shrinkage, of the muscle where it is injected, including the temporalis muscles.
To ensure optimal results and minimize potential side effects, it is crucial to select an experienced injector. The injector should be knowledgeable about the exact dosage and location of the Botox injections, as these factors can vary depending on individual needs. While side effects are rare with an experienced injector, it is always advisable to prioritize safety and seek qualified medical advice before undergoing any cosmetic procedure.
In summary, while Botox injections can be an effective method for shrinking the temporalis muscles, repeated injections at regular intervals may be necessary to maintain the desired results. It is important to consult with experienced medical professionals who can tailor the treatment plan to your specific needs and ensure safe and effective outcomes.
