Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Tonsil Dressing
This oral wound dressing in powder form is applied immediately post-tonsillectomy as a single intervention on the tonsillectomy wound. The powder binds to the wound becoming a gel and forms a protective barrier.
Intervention code [1] 286509 0
Treatment: Devices
Comparator / control treatment
Control: standard treatment
Participants enrolled and randomized to the standard treatment arm will receive a tonsillectomy with standard post-operative care and no wound dressing.
Control group
Active

Outcomes
Primary outcome [1] 288853 0
The primary purpose of this study is to measure the differences in postoperative pain in subjects undergoing electrodissection monopolar diathermy tonsillectomy who are treated with the Tonsil Dressing (treatment cohort) compared to those undergoing the same procedure who do not receive the Tonsil Dressing (control cohort).
Timepoint [1] 288853 0
Pain is measured by the study participant twice daily for 14 days using a visual analogue scale from 0 to 10.
Secondary outcome [1] 301150 0
A secondary objective is to measure the differences in postoperative recovery time (i.e. return to normal activity and return to normal nutritional intake) in the treatment cohort compared to the control cohort.
Timepoint [1] 301150 0
Postoperative recovery time is measured by the study participant twice daily for 14 days using a questionnaire in a subject notebook.
Secondary outcome [2] 301151 0
Safety data will be collected categorized and evaluated.
Postoperative complications and events will be recorded daily by the participant in a Subject Notebook (diary) and/or reported directly to the clinic. Adverse events will be assessed by the investigator during study procedures (e.g. surgery or discharge) and with an oral cavity examination at the follow-up visit (day 15-25) and upon review of the Subject Notebook. Adverse events will be recorded on specific case report forms.
Potential Adverse events include the following:
Allergic reaction,
Post-operative bleeding,
Laryngospasm,
Dehydration,
Nausea,
Vomiting,
Foreign Body Response,
Referred Ear Pain,
Oedema,
Erythema,
Infection,
Surgical Pain,
Prolonged Surgical Pain,
Abnormal or Impaired Wound Healing,
Permanent change in voice,
Nasal regurgitation.
Timepoint [2] 301151 0
Safety data will be collected by the study participants daily for 14 days postoperatively and by the investigator at the follow-up visit occurring at day 15 - 25 postoperatively.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects will be recruited from the practices and clinics of the participating Study Investigators. The potential subject will be assessed for preliminary eligibility, and subsequently interviewed for their interest in the study and willingness to comply with the study protocol. Potential candidates will be provided the Participant Information Sheet, and will be given ample opportunity to ask questions and receive further information from the study personnel before deciding whether or not they will participate in the study. If the candidate agrees to participate, he/she will be asked to sign the Informed Consent Form.
Once the Informed Consent Form is signed, the subject will be considered enrolled in the study.

Allocation is concealed through the use of central randomization by a computer system.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization will be assigned through a computer database associated with the electronic case report form system. Once the preliminary participant information has been entered into the system the computer program will select the randomization assignment for that subject.

Simple randomisation using a randomisation table created by computer software (i.e. computerized sequence generation).
Masking / blinding

Statistical methods / analysis
As this is a feasibility study, and the endpoints do not require a quantified definition of success, no statistical analysis will be undertaken. The data resulting from this study will be summarized and interpreted by the Sponsor using interim assessments; in addition, a final report will be generated after all data are collected.
