Objective: The aim of this study was to compare mouth opening exercise outcomes with wooden tongue depressors (WTDs) versus Heister jaw opener (HJO) in improving mouth opening after reconstruction of the surgical defect with buccal fat pad (BFP) in oral submucous fibrosis (OSF) patients.
Materials And Methods: Fifty consecutive patients were divided randomly into two groups (25 patients in each group) corresponding to postoperative physiotherapy with WTDs (group 1) and HJO (group 2) respectively. Groups 1 and 2 were evaluated for maximum interincisal distance at 3, 6 and 12 months of follow up. In groups 1 and 2, mouth opening differed substantially at all periods of follow up from preoperative values.
Results: The increase in mouth opening was greater in group 2 at 3 ( = 0.003) and 6 ( = 0.010) month follow up visit respectively. No relevant difference was observed in mouth opening between groups 1 and 2 at 12 months ( = 0.066). The mean increase in mouth opening at 12 months compared with the preoperative value was 22.2 mm in group 1 and 25 mm in group 2.
Conclusion: We conclude both WTDs and HJO are effective in improving postoperative mouth opening in OSF surgical patients.

Temporomandibular disorder (TMD) is the most prevalent painful condition in the craniofacial area. Recent studies have suggested that external or intrinsic trauma to the temporomandibular joint (TMJ) is associated with the onset of painful TMD in patients. Here, we investigated the effects of TMJ trauma through forced-mouth opening (FMO) in mice to determine pain behaviors and peripheral sensitization of trigeminal nociceptors in both sexes.

Temporomandibular joint osteoarthritis (TMJOA) is a painful inflammatory condition that limits mouth opening. Cell-derived exosomes, which have anti-inflammatory effects, are emerging as a treatment for TMJOA. Injection of dental pulp stem cells (DPSCs), which secrete exosomes, can moderate tissue damage in a rat model of TMJOA.

Aim: We aimed to examine the influence of various prognostic factors on the outcome of external auditory canal (EAC) cancer and create a graphical prediction tool, marking a first in this field, premised on these determinants.
Methods: We retrospectively analysed 173 patients with EAC cancer, making this the largest patient cohort in the literature. Survival analysis was performed using the Kaplan-Meier method, and the log-rank test was used to assess the differences between established prognostic variables.

Background: This case report details a true hemifacial hyperplasia with temporomandibular joint ankylosis case managed through a multidisciplinary approach involving department of oral and maxillofacial surgery, orthodontics, and prosthodontics.
Case Presentation: A 42-year-old female patient presented with a chief complaint of limited mouth opening. Clinically, the patient exhibited severe facial asymmetry due to hyperplasia of the left facial region.

The increasing use of anti-programmed cell death 1 (PD-1) immune checkpoint blockade has led to the emergence of immune-related adverse events (irAEs), including dysfunction of the submandibular gland (SMG). In this study, we investigated the immunoregulatory mechanism contributing to the susceptibility of the SMG to irAEs. We found that the SMGs of PD-1-deficient mice and anti-programmed cell death ligand 1 (PD-L1)-treated mice harbor an expanded population of CD8 T cells.
