ADHESION- An adhesion is a band of scar tissue that binds together two anatomic surfaces which are normally separated from each other.
ANKYLOSIS– Ankylosis refers to the partial or complete inability to open the mouth which results in functional and growth deformation of the mandible.
ANTERIOR DISC DISPLACEMENT WITHOUT REDUCTION – Dislocation of the disc away from its normal position to a position in front of the condyle.

ANTI-INFLAMMATORY– Drug that reduces swelling.
ARTICULATE– To join or connect together loosely to allow motion between the parts.
To unite by forming a joint or joints.
ARTHROCENTESIS– TMJ arthrocentesis is a surgical procedure done on the temporomandibular (or jaw) joint. It is considered a minor procedure, and is generally performed in the oral and maxillofacial surgeon’s office or in an outpatient surgical center.
ARTHROPLASTY– The arthroplasty, or sometimes called arthrotomy, is an open joint surgical procedure performed on the jaw joints under general anesthesia in the hospital. The incision is made similar to a face lift incision (along the ear), and the joint space is exposed for the surgeon to see. This allows for the removal of adhesion‘s, osteophytes (bone spurs), fibrous or bony ankylosis (fusion), tumors, etc. The surgeon can also repair the discs by suturing them into place or implant anything from a temporalis muscle graft to ribs.
ARTHROSCOPY– The arthroscopy is more involved and invasive than TMJ arthrocentesis. This procedure is almost always done in the outpatient facilities (or day surgery) at the hospital. A small scope (camera) is used to take a look inside the temporomandibular joint. Some surgeons will not only look inside, but may perform other procedures like suturing the discs in place, or removing loose scar tissue.

BALANCED OCCLUSION– Occlusion in which the teeth are in harmonious working relation.
BIOFEEDBACK– A method of treatment that uses monitors to feed back to patients physiological information that they may not be aware of. By watching the monitor patients can learn by trial and error how to adjust their thinking in order to control “involuntary” bodily processes such as blood pressure, temperature, and brain wave activity.

FUNCTIONAL ORTHODONTICS- Functional orthodontics involves the use of custom-fabricated dental appliances and or braces to move the teeth into proper alignment in order to preserve the health of the temporomandibular joints and jaw muscles.
GLENOID FOSSA– The socket within the temporal bone of the skull which forms the roof and side of the temporomandibular joint
INTERNAL DERANGEMENT– Mechanical fault that interferes with the smooth action of temporomandibular joint. It is associated with a displaced disc, a dislocated jaw or injury to the condyle.
JAW– The bones below the mouth (mandible) and the bone above the mouth (maxilla).
JOINT– A joint is the area where two bones are attached for the purpose of motion of body parts. A joint is usually formed of fibrous connective tissue and cartilage.
JOINT VIBRATION ANALYSIS (JVA)- Records the vibrations made by joint tissues during movement. JVA records vibrations, not sounds.
LEVATOR SCAPULAE MUSCLE- Skeletal muscle that is situated at the back and side of the neck. It’s main function is to lift the scapula or shoulder blade.
MALOCCLUSION– Misalignment of the upper and lower teeth when the jaw is closed and their surfaces come in contact. The condition may also be referred to as an irregular bite, crossbite, or overbite.

TINNITUS– Tinnitus is most commonly referred to as ‘ringing in the ears’ and can be defined as the conscious experience of noise with no apparent external source. Tinnitus can vary in the way it sounds, its severity, as well as its annoyance. Ringing, chirping, or even clicking sounds may occur a few times a month or many times in one day; for a few moments or hours; or can even be constant.

Thank you so much for this. It is truly helpful in my research. I am currently trying to find out information on non-surgical options for fibrous ankylosis, (are there any?), and every website I find is in doctor-speak. Do you have any information on this and/or on the surgical procedure they use to correct it? I have to go back in five days to find out if it’s fibrous or boney ankylosis, (just by “feel” I think it’s fibrous), and he said if it is fibrous, he will do an arthroplasty to correct the adhesion and insert a fat graft. That’s not much information. Still not sure what’s involved in the surgery.
Thank you, as always, for your help and support.
Actually, I just found the information on the surgery that you have. That answers part of my question.
The second part, however, about any non-surgical treatments for fibrous ankylosis, I am still having a hard time finding.
Am I wishing for something that does not exist?
