Surgical Management of Temporomandibular Joint Ankylosis with Mersilene Mesh Interpositional Arthroplasty: A Case Series Study.

Ankylosis of the temporomandibular joint (TMJ) is one of the most prevalent TMJ disorders in patients who have experienced trauma. Due to the high risk of recurrence, gap arthroplasty without interpositional material has been gradually discontinued as a treatment for TMJ ankylosis. After arthroplasty surgery, various interposition materials have been used to prevent a recurrence. Reporting on the effectiveness of TMJ bony ankylosis treatment using Mersilene mesh interpositional arthroplasty is the purpose of this study.This was a retrospective study carried out on five patients of TMJ ankylosis. All patients were treated through a Mersilene mesh interpositional arthroplasty procedure from January 2016 to April 2022 in Dr. Soetomo General Hospital and Universitas Airlangga General Hospital and evaluated 3 months postoperatively for the functional stability of TMJ. The result is preoperative mouth opening ranged between 0.7 and 13 mm. The patients achieved the interincisal opening between 27 and 40 mm postoperatively and had no complications for 3 months. In conclusion, Mersilene mesh interpositional arthroplasty is a very effective surgical treatment for TMJ bony ankylosis to achieve maximum mouth opening and avoid recurrences. The prevention of ankylosis recurrence necessitates thorough rehabilitation.

Analyses of Bone Regeneration Capacity of Freeze-Dried Bovine Bone and Combined Deproteinized-Demineralized Bovine Bone Particles in Mandibular Defects: The Potential Application of Biological Forms of Bovine-Bone Filler.

OBJECTIVE: This study aimed to evaluate bone regeneration capacity of FDBX granules compared to composite DBBM/DFDBX granules for filling of bone defect in rabbit mandible. MATERIAL AND METHODS: Critical size defects were created in 45 rabbits' mandible. The defect in the control group is left untreated, while in other groups the defects were filled with FDBX granules and composite DBBM/DFDBX granules, respectively. Specimens were collected at 2, 4, and 8 weeks for histology and immunohistochemical analyses. Significant difference is set at p-value < 0.05. RESULTS: The osteoblast-osteoclast quantification, osteoblast expression of Runx2, alkaline phosphatase, collagen-I, and osteocalcin, and osteoclast expression of receptor activator of NF-kB ligand (RANKL) and osteoprotegerin (OPG) in FDBX groups were statistically comparable (p > 0.05) with the composite group, while OPG/RANKL ratio, bone healing scores, and trabecular area were significantly higher (p < 0.05) in the composite compared to FDBX group. CONCLUSION: Composite DBBM/DFDBX granules, within the limitation of this study, has better bone forming capacity than FDBX granules for filling of bone defects in the mandible.

A model to standardize safety and quality of care for cupping therapy.

Cupping therapy has historical, traditional and religious value. It is increasingly popular in the field of complementary, alternative and integrative medicine. However, standards for safety and quality of service are absent. Although it is generally considered safe, cupping therapy can cause adverse events. Most of these events are predictable and preventable. A comprehensive approach to patient eligibility and therapist selection, along with compliance with standard operational procedures is essential to regulate the safety of the practice. Here we discuss a model framework for standardizing safety and quality of care. We recommend that this model be used routinely by cupping therapists and their associations on a nation-wide scale.
