“…In more recent times, the temporalis muscle/fascia flap has gained popularity as an interpositional material because it is close at hand, has a local blood supply and is relatively simple. This separates the cut bony surfaces but there may be scarring of the muscle, limiting mouth opening unless an ipsilateral coronoidectomy is performed 12,14,21,22 . The tissue may be too soft to resist the compression of the ramus.…”

“…These authors also noted that this was a progressive disease and claimed that early detection and surgical treatment could minimize the amount of condylar bone resorption. Smith et al [1999] assessed 28 joints of patients with TMD and found that 24 of them showed signs of bony degeneration such as condylar flattening, cortical erosion and joint space alterations.…”

Several tissues are involved in temporomandibular joint (TMJ) health, including synovial fluid, the TMJ disc, articular cartilage, and subchondral bone. This article focuses upon bone resorption in temporomandibular joint disorders (TMD) and has the following objectives: (1) to provide a brief review of the current understanding of bone formation and bone resorption (bone remodeling); (2) to present selected case studies which illustrate the spectrum of bone resorption patterns in TMD patients of various ages; (3) to review previous reports in the literature describing loss of subchondral bone in TMD, and (4) to discuss the interaction between osteoporosis and TMD and the potential role for antiresorbing agents in TMD therapy.

“…The radiological modalities (including MRI, electron beam CT) visualise quite well the vascularisation of the diverse tissues. In comparison with scintigraphy they are not so successful for evaluating viability [15,16]. Furthermore, radiological investigations are hampered by artefacts due to diverse metal and dental implants.…”

In oro-maxillofacial malignancies, new therapeutic approaches are placing changing demands on the diverse diagnostic modalities. In contradistinction to mandibular reconstruction of former years, the transplants (microvascular anastomosed pedicled flaps, "flaps") now consist of one or more arteries feeding a soft tissue component attached to a piece of bone suitably fitted to fill the defect. We addressed the diagnostic value of technetium-99m tetrofosmin scintigraphy in differentiating between viability and non-viability of the soft tissue portion of flaps in the immediate postoperative assessment. A total of 60 patients who had received flaps for reconstruction of the mandible after partial resection were investigated with (99m)Tc-tetrofosmin 3-5 days after surgery. Scintigraphy consisted of (a) radionuclide angiography, (b) static planar imaging in four projections starting at 10 min post injection, and (c) single-photon emission tomography (SPET) performed immediately after the planar imaging. Normal perfusion associated with no defects throughout the soft tissue portion of the transplant was observed in 46/60 patients. This scintigraphic pattern was identical to viability and normal postoperative follow-up. Hypoperfusion and small defects on planar and SPET images indicated viability and uncomplicated postoperative healing in 6/60 patients, but non-viability/inadequate healing of the flap in 4/60 patients. Absence of perfusion combined with a large defect on static planar and SPET images definitively showed the non-viability of the flap (4/60 patients). It is concluded that (99m)Tc-tetrofosmin scintigraphy is a sensitive diagnostic tool for the immediate postoperative assessment of the viability and the adequacy of implantation of the soft tissue portion of flaps. Therefore tetrofosmin scintigraphy is an important modality in order (a) to define the optimal therapeutic regimen in the immediate postoperative period and (b) to provide better prognosis.
