Study summary

The purpose of this study is to evaluate the efficacy of lavender aromatherapy in adult patients undergoing awake otolaryngologic procedures in the outpatient clinic setting. The main questions it aims to answer are:

  • Does lavender aromatherapy help reduce anxiety and/or pain, and improve patient comfort during awake otolaryngologic procedures in the clinic?
  • Do patients subjectively find aromatherapy relaxing and/or beneficial during the procedure?

Researchers will compare lavender aromatherapy to placebo (an odorless liquid) to see if lavender aromatherapy helps improve patient comfort during their awake procedure

Participants will:

  • Have their scheduled procedure performed with lavender aromatherapy or placebo during the duration of the procedure
  • Take a short, less than 1 minute questionnaire both before and after the procedure, describing their levels of anxiety, pain and subjective impressions of the aromatherapy

Exclusion criteria

Exclusion Criteria:

  • to fragrances
  • Taking systemic NSAIDs or other systemic pain-relieving medications within 48 hours

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

What researchers measure

Primary outcomes

  1. Change in visual analog scale anxiety, measured on a 10 cm scale

    A 10 cm visual analog scale is widely utilized to measure procedural anxiety, rated from 0 to 10, with 10 being the highest level of anxiety. The patient will provide a vertical mark above their level of anxiety. This number measured in mm (0-100) will be recorded both immediately before the procedure, and after the procedure, where the patient will record their average level of anxiety during the procedure. The change between pre-procedure, and post-procedure, will be recorded for each patient and compared between the lavender aromatherapy and placebo groups. The mean and median pre-procedure and post-procedure values will also be compared between the groups.

    Time frame: Baseline, Periprocedural and Immediately after the procedure

  2. Likert scale of pain, measured on a scale of 0-10

    Patients will be asked to rate their your average level of pain on a scale of 0 (no pain) to 10 (worst possible pain) on a post-procedural questionnaire

    Time frame: Immediately after the procedure

  3. Likert scale subjective improvement with pain, measured on scale of 1-5

    Patients will be asked in post-procedural questionnaire if they felt the aromatherapy helped with pain during the procedure, on a scale of 1 (strongly disagree) to 5 (strongly agree)

    Time frame: Immediately after the procedure

Secondary outcomes

  1. Subjective Impressions of Lavender Aromatherapy, measured on Likert scale and in Yes/No format in post-procedural questionnaire

    Patients will be asked in a post-procedural questionnaire their subjective impressions of the lavender aromatherapy or placebo. The questions will be outlined as below: Did you feel the aromatherapy was calming during the procedure? 1 2 3 4 5 (1 = strongly disagree, 5 = strongly agree) Did you find the scent pleasant? 1 2 3 4 5 (1 = strongly disagree, 5 = strongly agree) Do you use aromatherapy or essential oils regularly? Yes No Have you ever used aromatherapy or essential oils in the past? Yes No How likely are you to recommend the aromatherapy for future patients undergoing awake procedures? 1 2 3 4 5 (1 = strongly disagree, 5 = strongly agree)

    Time frame: Immediately after the procedure

Individual participant data

Plan to share: No — IPD will not be shared with other researchers in order to protect patient privacy, as these patients will be undergoing awake procedures at only 1 location, and thus their results may be identified even after anonymization or de-identification.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Dec 2025; primary completion for Jan 2027, 13 months later.

Of 67 non-industry interventional studies with no phase under Thyroid Nodule, half reached primary completion within 30 months of starting (the median), counting those still running; a quarter within 13 and three quarters within 46. This study's planned 13 months is below that.

Counting every sponsor, half of 71 studies reached it within 30 months; a quarter within 14 and three quarters within 46.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 23, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
