Introduction: Trismus has been considered a late complication of cancer treatment. It can occur prior to treatment, mainly caused by tumor invasion or muscle spasms induced by the presence of the tumor.
Objective: In this study, we evaluated the incidence of trismus and its effect on oral health in patients with malignant neoplasms of the oral cavity before performing the cancer treatment.
Methods: This review was carried out via interviews, visual clinical inspection and objective measurement of maximal mouth opening in 35 consecutive patients. Trismus was defined as a maximal mouth opening <35mm.
Results: Trismus was observed in 15 patients, with a total incidence of 42%. A high rate of tooth loss was recorded, and trismus association with tooth loss was statistically verified using the Chi-square and Fisher's exact tests, the t-student test and Mann-Whitney non-parametric test. All tests were performed at p<0.05.
Conclusion: Edentulous patients are eight times more likely to have trismus compared to patients that are partially and fully dentate. Trismus was demonstrated to be correlated with tooth loss; however other oral health conditions were not shown to be a modifying factor.

Pedicle ossification following mandibular reconstruction using fibular free flap in a patient with osteoradionecrosis of the jaw: a case report.

Article Synopsis
- Pedicle ossification is a rare complication that can occur after using a fibular free flap (FFF) for mandibular reconstruction, potentially simulating tumor recurrence and leading to diagnostic challenges.
- A case study of a 38-year-old male with squamous cell carcinoma highlighted how postoperative complications led to the need for FFF reconstruction, and over 4 years, CT scans showed ossification in the flap's vascular pedicle, yet the patient remained asymptomatic.
- Regular imaging and clinical assessments are key to distinguishing ossification from tumor recurrence, with surgery usually only considered if symptoms arise.
Platelet-rich fibrin application after mandibular third molar extraction: an umbrella review.

Objectives: The aim of this study was evaluate the effect of Platelet-Rich Fibrin (PRF) in patients after mandibular third molar extraction through an analysis of the most current literature on systematic reviews and meta-analyses.
Data, Sources And Study Selection: By using computer-assisted search technology, we comprehensively searched several reliable databases, such as China National Knowledge Infrastructure (CNKI), WanFang Data, the Chinese biomedical literature database, PubMed, Web of Science, EMBase, and the Cochrane Library, and performed a systematic retrospective meta-analysis on all of the collected studies on the therapeutic effects of PRF on patients after mandibular third molar extraction. A total of nine meta-analyses were performed in this study, and all nine studies were rated as high quality on the basis of the AMSTAR 2 criteria.

The scarring stage of noma disease often presents with composite tissue loss involving hard and soft tissues with resultant fibrosis making reconstruction a challenge. Microvascular reconstruction option is associated with good outcomes when the expertise is available. Trismus, which is caused by either soft tissue fibrosis or the union of the coronoid to the zygomatic complex, is also a common presentation.

Third molar extraction is one of the most common interventions in oral surgery. It is usually associated with postoperative pain, edema, and trismus. The severity of these sequelae can be related to the amount of surgical trauma and the duration of the extraction.
