condylectomy is a surgical procedure that removes part or all of a mandibular condyle (the rounded end of the lower jaw that forms the jaw joint). It is most commonly discussed in relation to the temporomandibular joint (TMJ), jaw growth problems, joint damage, or certain tumors. The goal is typically to reduce abnormal bone, restore function, or create a stable joint position. It is usually performed by an oral and maxillofacial surgeon as part of TMJ or jaw surgery care.

disc displacement is a change in the position of the temporomandibular joint (TMJ) disc relative to the jaw joint surfaces. In plain terms, the small “cushion” inside the jaw joint is not sitting where it usually does. It is most commonly discussed in TMJ-related evaluations for jaw clicking, locking, or limited opening. Clinicians use the term to describe a pattern of joint mechanics, not a dental filling material or a procedure by itself.

TMJ arthroplasty is a surgical procedure to repair, reshape, or reconstruct the temporomandibular joint (TMJ). The TMJ is the jaw joint in front of the ear that helps you open, close, and move your jaw. TMJ arthroplasty is commonly used when joint damage or joint “locking” does not improve with non-surgical care. It may involve removing scarred tissue, repositioning structures, or placing a joint implant, depending on the case.

arthroscopy is a minimally invasive surgical procedure used to look inside a joint using a small camera. It is commonly performed in orthopedic care (such as knee or shoulder joints). In dental-related care, arthroscopy may be used for the temporomandibular joint (TMJ), the joint in front of the ear that helps the jaw open and close. It can be used for diagnosis, treatment, or both, depending on the case.

arthrocentesis is a minimally invasive procedure that enters a joint space with small needles. In dentistry, it most commonly refers to arthrocentesis of the temporomandibular joint (TMJ), the jaw joint in front of the ear. The joint is gently washed (lavaged) with sterile fluid to reduce inflammation and improve movement. It is typically considered when jaw pain or limited opening persists despite conservative care.

TMJ surgery refers to surgical procedures performed on the temporomandibular joint (TMJ), the joint in front of each ear that connects the lower jaw to the skull. It is used to diagnose, repair, reposition, or replace joint structures that are not responding to conservative (non-surgical) care. TMJ surgery may involve minimally invasive techniques (such as arthrocentesis or arthroscopy) or open-joint operations (arthrotomy). It is most commonly discussed in the context of persistent jaw pain, limited opening, joint locking, or structural joint disease.

TMJ disorder is an umbrella term for problems affecting the temporomandibular joint (TMJ), the jaw muscles, or both. It commonly describes jaw pain, joint noises (clicking/popping), and difficulty opening or moving the jaw. The TMJ connects the lower jaw (mandible) to the skull and helps with chewing, speaking, and swallowing. Dentists and physicians use the term when evaluating facial pain and jaw-function symptoms that may involve the TMJ system.

ranula is a mucus-filled swelling that most often appears on the floor of the mouth. It is typically related to leakage or blockage of saliva from a salivary gland, most commonly the sublingual gland. ranula is a clinical term used in dentistry, oral surgery, and ear–nose–throat (ENT) settings. People often describe it as a soft, bluish, “bubble-like” lump under the tongue.

A mucocele is a soft, mucus-filled swelling that most often appears on the inner lower lip. It forms when saliva from a minor salivary gland leaks or becomes trapped in nearby tissue. In dentistry and oral medicine, mucocele is a common, usually benign cause of a “bubble-like” oral lump. It is discussed in clinical exams, differential diagnosis, and (when needed) minor oral surgery planning.

A fibroma is a benign (non-cancerous) growth made mostly of fibrous connective tissue. In the mouth, it most often appears as a small, firm bump on the cheek, lips, tongue, or gums. Many oral fibromas are “reactive” lesions linked to repeated irritation, such as cheek biting or rubbing from dental appliances. Dentists commonly recognize fibroma during routine exams and may confirm it with a biopsy when needed.
