Buccal Fat Reconstruction for Tonsil Cancer
(BOLT Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests whether adding buccal fat reconstruction (using cheek fat to support healing) during surgery for tonsil cancer can reduce postoperative pain. Researchers aim to determine if this technique alleviates pain during rest and swallowing and its impact on pain medication use, complications, or feeding tube necessity. Participants will undergo surgery with or without this reconstruction and compare their experiences. This trial may suit individuals with early-stage tonsil cancer requiring transoral robotic surgery. As a Phase 2 trial, the research focuses on assessing the treatment's effectiveness in an initial, smaller group of participants.
Do I have to stop taking my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that buccal fat reconstruction is safe for tonsil cancer surgery?
Research has shown that using buccal fat (fat from the cheek) for reconstruction is generally safe. One study focused on using this fat to repair the inner lining of the mouth and found the procedure effective and well-tolerated, with few complications. This suggests it is a reliable method.
Although specific data on using buccal fat reconstruction for tonsil cancer is lacking, its success in other mouth areas is promising. This indicates it could be a safe option for this new use as well. Always discuss potential risks and benefits with the trial team to make an informed decision.12345Why do researchers think this study treatment might be promising?
Researchers are excited about buccal fat reconstruction for tonsil cancer because it offers a new approach to reconstructing the mouth area after surgery. Unlike standard treatments like radiation or chemotherapy, which primarily aim to kill cancer cells, this technique focuses on improving the healing and function of the mouth following surgical removal of cancerous tissue. By using buccal fat, which is naturally found in the cheeks, this method could enhance recovery and maintain better oral function, potentially leading to improved quality of life for patients.
What evidence suggests that buccal fat reconstruction might be an effective treatment for reducing pain after transoral robotic surgery for tonsil cancer?
This trial will compare two surgical approaches for tonsil cancer: transoral lateral oropharyngectomy alone and transoral lateral oropharyngectomy with buccal fat reconstruction. Research has shown that buccal fat reconstruction can be beneficial in throat cancer surgery. One study found that using a buccal fat pad flap, along with a buccinator myomucosal flap, effectively covers areas in the throat after cancer removal. This method reliably heals areas affected by cancer surgery and helps fill gaps left by tissue removal, potentially reducing pain and improving swallowing post-surgery. This technique is a valuable option for patients undergoing throat cancer surgery. Overall, buccal fat reconstruction offers promising improvements for those recovering from tonsil cancer surgery.46789

Are You a Good Fit for This Trial?
This trial is for patients with certain throat cancers, including oropharynx and tonsil cancer, who are undergoing transoral robotic surgery. Participants must be able to provide pain and swallowing assessments post-surgery. Specific inclusion and exclusion criteria details were not provided.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Buccal Fat Reconstruction
Trial Overview
The study is testing if using buccal fat (fat from the cheek) to reconstruct the surgical area after transoral robotic surgery can reduce pain compared to not using it. Pain levels during rest and swallowing will be measured, along with other factors like complications and medication usage.
