Mechanism Exploration: How do changes in inflammatory markers, obstruction severity, and olfactory test results explain the potential benefits of this treatment approach?

Intra-Sinus Povidone-Iodine and Budesonide After Endoscopic Sinus Surgery for Chronic Rhinosinusitis

Endoscopic sinus surgery (ESS) is commonly performed in patients with chronic rhinosinusitis (CRS) to improve sinus drainage and allow better delivery of topical therapies after surgery. Despite surgery, postoperative inflammation can persist and negatively affect healing and outcomes. This randomized, double-blind, placebo-controlled clinical trial will evaluate whether intra-sinus administration of a gel-forming suspension containing povidone-iodine and budesonide improves postoperative endoscopic outcomes of the sinus cavities three months following ESS, compared with placebo.

Efficacy of Lavender Aromatherapy on Anxiety and Pain Reduction During Awake Otolaryngologic Procedures

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.

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

Treatment Decision-Making Among Patients With Chronic Rhinosinusitis

This project aims to develop and pilot-test a bilingual, patient-centered clinical decision support (PC CDS) web application for individuals with chronic rhinosinusitis (CRS), a condition affecting 16% of U.S. adults annually and significantly impacting quality of life. While endoscopic sinus surgery (ESS) is a recommended treatment for medically refractory cases, many patients experience barriers that lead to surgical hesitancy. Prior research at USC revealed significant disparities in ESS uptake (Odds Ratio = 7.92; 95% Confidence Interval: 2.95-21.28), highlighting the need for more tailored decision support. The PC CDS will include educational resources, Large Language Model-assisted patient narratives, and a provider communication module to facilitate shared decision-making (SDM). The study has three aims: (1) to develop the tool; (2) to evaluate its feasibility in a randomized controlled trial with 50-60 patients from USC clinics; and (3) to assess outcomes using surveys and interviews. Participants will be randomized into either a control group (receiving standard CRS informational handouts) or an intervention group (receiving standard care plus the PC CDS tool). Quantitative surveys will measure treatment choice, decision quality, SDM involvement, CRS knowledge, provider trust, and care satisfaction. Qualitative interviews will explore participants' healthcare journeys and experiences with the tool. Guided by experts in health technology and rhinology and in collaboration with a Patient Advisory Group, the study aims to ensure patient-centered design and lay the groundwork for future implementation and external funding (e.g., AHRQ).

Effectiveness of Penthrox vs Placebo in Sinus Procedures, a Clinical Trial

The goal of this randomized controlled trial is to evaluate the effectiveness of inhaled methoxyflurane (Penthrox) as an analgesic for patients undergoing minor rhinology and sinus procedures, specifically comparing it to a placebo control. The primary question the study aims to answer is: Does methoxyflurane provide superior pain relief compared to placebo during minor sinus procedures, as measured by the Visual Analog Scale (VAS)? If there is a comparison group: Researchers will compare the effects of Penthrox to the placebo (saline + one drop of methoxyflurane) to see if it provides better pain relief, reduces anxiety, and leads to fewer complications, including bleeding. Participants will be asked to: Inhale 3 mL of Penthrox or placebo during their procedure. Complete a VAS scale to assess pain. Complete anxiety assessments pre- and post-operatively. Be monitored for complications such as bleeding and other adverse effects. This study will help determine the effectiveness of Penthrox as a non-invasive, quick-acting analgesic for minor sinus surgeries.

Comparative Effects of Therapeutic Ultrasound and Sinus Massage in Chronic Rhinosinusitis: a Randomized Controlled Study

This is a randomized controlled trial. Previous studies show that both therapeutic ultrasound and sinus massage techniques have significant results in Chronic Rhinosinustis (CRS). However, there is no comparative study carried out between these two to show which technique has more effects in CRS. This study will determine their comparative effects on: 1. Pain measured on Numerical pain rating scale 2. Sinonasal symptoms measured on sino-nasal outcome test questionaire 3. Quality of life measured on rhinosinusitis disability index (RSDI) 4. Nasal inspiratory airflow measured on peak nasal inspiratory flow meter. Participants of chronic rhinosinusitis will be selected according to the diagnostic criteria of American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) and will be randomly allocated into three groups. All three group will continue to receive medical intervention. Additionally one group will receive therapeutic ultrasound while other group will receive sinus massage. Whereas third group will be control group and won't receive any additional treatment. Data will be collected at Foundation University College of Physical Therapy and Fauji Foundation Hospital.
