<p class="abstract"><strong>Background:</strong> <span lang="EN-IN">The aim of this study was to evaluate efficacy of segmental cone beam computed tomography (CBCT) in detecting bony changes in condyle and thickness of roof of glenoid fossa in temporomandibular joint (TMJ) disorders.</span></p><p class="abstract"><strong>Methods:</strong> The study group comprised of 10 temporomandibular disorders (TMD) patients of either sex between the age group of 20-60 years diagnosed as TMDs by clinical evaluation using the research diagnostic criteria was considered. After the clinical examination, radiographic investigations were carried out which included digital OPG, transcranial radiograph and CBCT scan. TMJ Evaluation included: (a) bony changes of the condyle (flattening, erosion, sclerosis, osteophytes, resorption); (b) joint space (normal, increased, reduced, bony contact between the condyle and the mandibular fossa); and (c) bony changes of mandibular fossa (normal, sclerosis, erosion, resorption). The radiographic findings were statistically analysed.<strong></strong></p><p class="abstract"><strong>Results:</strong> <span lang="EN-IN">Significant difference between OPG, transcranial and CBCT were found for the presence of erosion (P =0.000), thickness of roof of glenoid fossa (P =0.000), deformed contour (P =0.001), joint space (P =0.011), subchondral sclerosis (P =0.011), irregularity of articular surface and eminence (P =0.000), flattening (P =0.050). </span></p><p class="abstract"><strong>Conclusions:</strong> Using CBCT as imaging technique in our study to detect osseous changes in the TMJ was proved to be effective as compared to the conventional radiographic techniques, the results achieved with CBCT was 100%.The results obtained in our study prove to be a full proof one and it seems to promise to go one step closer to detect progression and severity of the osseous changes in the condylar head and mandibular fossa in patients with TMDs<span lang="EN-IN">.</span></p>
Gamma Knife radiosurgery (GKRS) is a type of radiation therapy used to treat tumors, vascular malformations and pain disorders. Gamma Knife radiosurgery utilizes specialized equipment which focuses 201 narrow beams of radiation on a tumor or other target. Although each beam has very little effect on the tissue it passes through, a strong dose of radiation is delivered to the site where all the beams meet. The precision of GKRS results in minimal damage to healthy tissues surrounding the target; thus having a lower risk of side effects compared with other types of radiation therapy. GKRS can be used to treat benign and malignant tumors, arteriovenous malformations, brain metastases and functional disorders such as trigeminal neuralgia (TN) and glossopharyngeal neuralgia, especially in idiopathic and medically refractory cases. It manages these conditions non-invasively, without the pain and risk of complication associated with traditional surgery with most patients being able to resume normal activities the following day. GKRS is also known as stereotactic radiotherapy, stereotactic radiosurgery, and fractionated stereotactic radiotherapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
