Force Sensor Study for Laryngeal Surgery

This study is looking at how much force is applied to your tongue and throat during direct laryngoscopy (a procedure where a doctor looks at your voice box) for laryngeal surgery. Researchers want to see if changing this force, using real-time measurements from a force sensor, can affect outcomes like pain, numbness, or taste after surgery. You would either have direct laryngoscopy with force modulation (where the force is adjusted) or without force modulation (standard care). The study will measure your pain using the Short Form McGill Pain Questionnaire at 1 day, 14 days, and 1 month after your surgery. This study is for adults aged 18 and older who are having laryngeal surgery with direct laryngoscopy. The study is currently unclear on its recruitment status and plans to enroll 100 participants.

Study design
This is an interventional study planning to enroll 100 participants. It compares direct laryngoscopy with force modulation to direct laryngoscopy without force modulation, with surgeons blinded to force measurements for the first 50 patients.
What's involved
You would undergo direct laryngoscopy as part of your laryngeal surgery. Your pain levels will be measured using a questionnaire at 1 day, 14 days, and 1 month after your surgery.
Compensation
Not stated in the trial record.
Follow-up
You will be followed for 1 month after your procedure to assess pain levels.

Eligibility criteria

Inclusion

\>18 years old with
undergoing laryngeal surgery with direct laryngoscopy

Exclusion

Prior history of tongue dysfunction such as glossectomy (hemi or total) or hypoglossal nerve injury
Patient inability to follow up after initial procedure
  • Short Form McGill Pain Questionnaire (SF-MPQ)1 day, 14 days, and 1 month post-operatively

    The SF-MPQ includes the following components: 15 descriptors: * 11 sensory, each rated 0=none, 1=mild, 2=moderate, 3=severe * 4 affective , each rated 0=none, 1=mild, 2=moderate, 3=severe. A Present Pain Intensity (PPI) scale (0=No Pain, 1=Mild, 2=Discomforting, 3=Distressing, 4=Horrible, 5=Excruciating) Visual Analogue Scale of average pain (VAS, 0-10 cm) - higher score is worse pain
