Complications of temporomandibular joint arthroscopy. A critical appraisal of the literature.

To search for the best available scientific evidence in relation to the reported overall and selective complication rates for arthroscopic surgery in patients presenting with internal derangement (ID) of the temporomandibular joint (TMJ). A comprehensive electronic search was conducted without data or language restrictions up to August 2023. Inclusion criteria were the following: study in humans, randomized or quasi-randomized controlled trials (RCTs), controlled clinical trials (CCTs), cohort studies and series of clinical cases.

Defining a Standard Set of Health Outcomes for Patients With Squamous Cell Carcinoma of the Head and Neck in Spain.

Purpose: A systematic, standardized collection of health outcomes during patient treatment and follow-up, relevant from the perspective of all stakeholders, is a crucial step toward effective and efficient disease management. This project aimed to define a standard set of health outcomes for patients with squamous cell carcinoma of the head and neck (SCCHN).

A randomized controlled preclinical trial on 3 interposal temporomandibular joint disc implants: TEMPOJIMS-Phase 2.

The effort to develop an effective and safe temporomandibular joint (TMJ) disc substitute has been one of the mainstreams of tissue engineering. Biodegradable customized scaffolds could approach safety and effectiveness to regenerate a new autologous disc, rather than using non-biodegradable materials. However, it is still technically challenging to mimic the biomechanical properties of the native disc with biodegradable polymers.

Is the "Habsburg jaw" related to inbreeding?

The "Habsburg jaw" has long been associated with inbreeding due to the high prevalence of consanguineous marriages in the Habsburg dynasty. However, it is thought that mandibular prognathism (MP) is under the influence of a dominant major gene. To investigate the relationship between the "Habsburg jaw" and the pedigree-based inbreeding coefficient () as a relative measure of genome homozygosity.

The Critical Peri-implant Buccal Bone Wall Thickness Revisited: An Experimental Study in the Beagle Dog.

Purpose: There is a lack of knowledge concerning the critical buccal bone thickness required for securing favorable functional and esthetic outcomes, conditioned to the dimensional changes after implant placement. A preclinical study was therefore carried out to identify the critical buccal bone wall thickness for minimizing bone resorption during physiologic and pathologic bone remodeling.

Materials And Methods: A randomized, two-arm in vivo study in healthy beagle dogs was carried out.

Diagnostic accuracy of the implant stability quotient in monitoring progressive peri-implant bone loss: An experimental study in dogs.

Objectives: To investigate the impact of progressive bone loss in an experimental peri-implantitis model in the dog upon the implant stability quotient (ISQ) measured in the course of induced and spontaneous conditions of disease, and to evaluate the association between the clinical parameters and ISQ.

Materials And Methods: Seventy-two implants were placed in 12 Beagle dogs. Of these, 36 implants in six dogs were assessed during ligature-induced peri-implantitis (three timepoints) and at one timepoint following a period of spontaneous progression.

Arthroscopy of the Inferior Compartment of the Temporomandibular Joint: A New Perspective.

Objective: Arthroscopy of the temporomandibular joint (TMJ) has become a well-standardized non-invasive procedure for the treatment of TMJ internal derangement (ID). Since the last 1980s, no clinical application for arthroscopy of the inferior compartment has been established because of the intrinsic difficulty of the technique and the believing of the absence of clinical relevance for treatment of ID.

Methods: We report on a particular case in which arthroscopy of the inferior joint compartment together with the examination of the upper joint space was performed in a patient with ID of the TMJ.

Bioengineered Temporomandibular Joint Disk Implants: Study Protocol for a Two-Phase Exploratory Randomized Preclinical Pilot Trial in 18 Black Merino Sheep (TEMPOJIMS).

Background: Preclinical trials are essential to test efficacious options to substitute the temporomandibular joint (TMJ) disk. The contemporary absence of an ideal treatment for patients with severe TMJ disorders can be related to difficulties concerning the appropriate study design to conduct preclinical trials in the TMJ field. These difficulties can be associated with the use of heterogeneous animal models, the use of the contralateral TMJ as control, the absence of rigorous randomized controlled preclinical trials with blinded outcomes assessors, and difficulties involving multidisciplinary teams.

Endoscopically-Assisted Zygomatic Implant Placement: A Novel Approach.

Background: Zygomatic implants (ZIs) have been proposed as a valid alternative to advance bone-grafting procedures in the rehabilitation of the severe atrophied upper maxilla, with a reported overall success rate of more than 95 %. Otherwise, the use of the endoscope has been described for the treatment of maxillofacial trauma, orthognatic surgical procedures, sinonasal pathology, salivary gland disease, and TMJ internal derangement. A careful identification of anatomical landmarks is of utmost importance while trying to avoid potential complications during the insertion of ZIs.
