Management of Temporomandibular Joint Ankylosis

Temporomandibular joint (TMJ) ankylosis is a pathologic condition where the mandible is fused to the fossa by bony or fibrotic tissues. This interferes with mastication, speech, oral hygiene, and normal life activities, and can be potentially life threatening when struggling to acquire an airway in an emergency. Attempting to open the mouth, stretching the periosteum, can also result in pain

5 Signs You May be Suffering from Obstructive Sleep Apnea

5 Signs You May be Suffering from Obstructive Sleep Apnea

Sleep apnea is one of the most prevalent sleep disorders in existence. However, it is estimated that of the 22 million adults that are afflicted, over 80% of cases go undiagnosed — which is troublesome considering the array underlying health problems that sleep apnea can cause.

Obstructive sleep apnea is by far the most common of the sleep apneas, appearing in 4% of males and 2% of females worldwide, and the form that our office specializes in treating. OSA is caused by an obstruction of the upper airway (usually muscle, tissue, or the tongue) that causes breathing problems during sleep, as well as lowers the amount of oxygen in the blood. Those afflicted may not even be aware that they have OSA — especially if they sleep alone — and often attribute the multitude of other issues to something else.

Here are 5 signs that you may be suffering from obstructive sleep apnea.


Excessive Snoring

Snoring is caused by a blocked air passage during sleep. Many patients aren’t even aware that they snore at all unless their attention has been brought to it by a bed partner. The presence of snoring doesn’t necessarily mean that a person has sleep apnea, and having sleep apnea doesn’t always mean that the person snores. However, the likelihood of sleep apnea being present in those that do snore is higher.


Pauses in breathing while falling asleep

During apnea, air is unable to proceed past the internal obstruction, which reduces blood flow to the brain. In order to compensate, the body sends a signal to the brain that it needs to breathe. The brain then wakes up, and causes the patient to choking, wheezing, or gasping sound.

Once the body gets the breath it needs, the patient goes back to sleep and the process can start over again. This event can occur anywhere from 5 times to 100 times throughout the course of the night. The ramifications of this due to a severe case of sleep apnea can impact a multitude of areas of life for the afflicted.


Persistent Fatigue

A commonly overlooked symptom of OSA is an unending feeling of fatigue. While it may seem to OSA patients that they’re getting a full-night’s rest because they were in bed for 8 hours, pauses in the patient’s breathing can cause them to awaken in the night and therefore compromising their quality of rest, resulting in a condition called excessive daytime sleepiness (EDS).

Symptoms of EDS include a lack of energy, the need for frequent naps, difficulties in concentration, and trouble waking up in the mornings. EDS can contribute to difficulty with communication and production at work.


Frequent Headaches

Headaches are one of the most common symptoms of sleep apnea. As the ability to breathe dissipates, oxygen naturally struggles to make it to the brain as opposed to an unafflicted sleeper. Decreased oxygen levels can lead to the widening of blood vessels in the brain, causing vascular headaches. This is one of the most-overlooked symptoms of OSA.



Not getting a regular night of rest can have psychological impacts as well. A lack of sleep can cause fluctuations in mood, making sufferers prone to anxiety and paranoia, as well as short-tempered and in severe cases, depressed.


If you’re experiencing any of the above symptoms, it may be a sign of OSA. Contact our office to learn about what options we have for you. Don’t suffer through another sleepless night. Take back your quality of life today.

3 Signs Corrective Jaw Surgery Could be an Option for You

movahed oms tmd and tmj surgery

Everyone experiences jaw pain from time-to-time, but the cause and subsequent treatment ranges from ibuprofen to surgery. But how do you know if that discomfort in your jaw is from sleeping in an awkward position or if it’s symptomatic of deeper issues?

Any time you experience oral pain, a visit to the dentist’s office should be in order, but many will let the problem persist, expecting it to self correct eventually. In fact, studies have shown that as much as 60% of the US population have experienced temporomandibular disorder  (TMD) symptoms, but only a fraction of these people will seek treatment.

Left untreated, TMD can cause pain in the neck, shoulders, and back, as well as headaches and tinnitus. These physical consequences can in-turn lead to non-physical ailments like depression, anxiety, and loss of sleep, among others. Simply put, TMD can wreak havoc on your quality of life.

So how do you know if your jaw pain requires more treatment than rummaging through the medicine cabinet? Here’s three signs that a call to Dr. Movahed may be in order.


difficulty chewing, biting, and speaking

Difficulty chewing, biting, and speaking

Experiencing pain as a result of chewing or biting (versus a persistent twinge) is a classic symptom of TMD. The jawbone is attached to the skull by two joints that allow the hinging motion of your mouth which can become damaged, and make any sliding motion extremely painful. While injections and pain medication can bring temporary relief, they act as more of a band-aid than a solution. A skilled oral surgeon can correct the problem permanently and eliminate the clicking sound that commonly accompanies severe jaw pain.


ear pain

Ear Pain

Many people commonly believe ear pain is the result of an infection. But according to The American Academy of Otolaryngology, the most common cause of ear pain is TMD. The muscles around the joint and the ligaments that hold the bones in the right spot are connected with the ear and supporting nerves, which causes the subsequent pain when the joint is damaged or worn. Hearing isn’t always impacted, but TMD can give a stuffy or clogged feeling within the ear.

Adjusting your diet to strictly soft foods such as eggs, vegetables, and noodles can alleviate the stress placed upon the joint, but often, the damage has already been done by the time a patient reaches the point where TMD is causing ear pain. At that stage, surgery could be an option.


restricted jaw movement

Restricted Jaw Movement

The TMJ acts as a fulcrum between the skull and jaw. When it is damaged, it struggles to facilitate adequate range of motion and becomes more difficult to move which can ultimately result in complications when chewing, talking, etc. Many will associate restricted jaw movement with a number of other musculoskeletal afflictions like impacted teeth and arthritis. If you’re consistently experiencing restricted movement, corrective jaw surgery for TMD can restore expected mobility in the jaw permanently.All of these symptoms can be the result of a litany of other afflictions, so if you’re experiencing any of them, it’s important to speak to your doctor about your options. But if you’re like the 30% of TMD sufferers who don’t seek immediate treatment, corrective jaw and/or TMJ surgery may still be an option for you. Give us a call and schedule a consultation to see if we can help.
