Collagen Matrix in Oral Cancer Surgery

January 6, 2026 updated by: SAYAH Charline

Postoperative Swallowing and Voice Outcomes After Collagen Matrix Reconstruction in Oral and Oropharyngeal Cancer Surgery

This study tend to evaluate postoperative phonation and swallowing after oncologic surgery of the oral cavity or oropharynx with application of a collagen matrix (Tachosil®). Patients are asked to complete a questionnaire the day before the surgery and at 1 and 6 months after.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Case group

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Swallowing evaluation
Time Frame: From enrollment (the day before the surgery) to 6 months postoperatively.
We use the Deglutition Handicap Index questionnaire to evaluative swallowing before and after surgery. Patients completed the questionnaires the day before surgery, and at 1 month and 6 months postoperatively.
From enrollment (the day before the surgery) to 6 months postoperatively.
Voice evaluation
Time Frame: From enrollment (the day before the surgery) to 6 months postoperatively.
We use the Voice Handicap Index questionnaire to evaluate the phonatione before and after surgery. Patients completed the questionnaires the day before surgery, and at 1 month and 6 months postoperatively.
From enrollment (the day before the surgery) to 6 months postoperatively.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Length of hospital stay
Time Frame: From the day before the surgery up to 3 weeks after surgery. The number of days between hospital admission and discharge to home was calculated.
We evaluate the length of hospital stay, it was expressed in days as mean and standard deviation
From the day before the surgery up to 3 weeks after surgery. The number of days between hospital admission and discharge to home was calculated.
time to oral feeding resumption
Time Frame: From the surgery up to two weeks.
Number of days between the surgery and the time the patient start to eat again by the mouth.
From the surgery up to two weeks.
incidence and onset of device-related complications
Time Frame: From the day of the surgery to one week after
Incidence of immunologic reaction to the collagen matrix (tachosil). Expressed in number and pourcentage.
From the day of the surgery to one week after

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
