Summary
A novel device significantly improved maximal incisal opening and quality of life for patients with trismus. This pilot study shows promising results for a new trismus treatment option.
Area of Science:
- Oncology
- Oral and Maxillofacial Surgery
- Rehabilitation Medicine
Background:
- Trismus, a common complication of head and neck cancer treatment, significantly impairs quality of life, nutrition, and oral hygiene.
- Existing trismus treatments often involve unquantified force and can be prohibitively expensive.
Purpose of the Study:
- To prospectively evaluate the impact of a novel trismus treatment device.
- To assess improvements in maximal incisal opening (MIO) and patient-reported outcomes.
Main Methods:
- A single-arm cohort study involving 17 patients with trismus.
- A 10-week treatment program utilizing a novel trismus device.
- Pre- and post-intervention assessment of validated measures for MIO and trismus-related function.
Main Results:
- A significant improvement in MIO of 12.6 mm was observed after the 10-week intervention.
- Patients reported improvements in trismus symptomology, including quality of life, swallowing, speech, and jaw pain.
Conclusions:
- This pilot study demonstrates the feasibility of a novel device for trismus treatment.
- Further research is needed to evaluate the efficacy, safety, and cost-effectiveness in larger, controlled studies.
