Trial Summary

What is the purpose of this trial?

Investigators will assess the usefulness of using ultrasound in office procedures for laryngology interventions. Participants who qualify will be adults who are undergoing superior laryngeal nerve block, injection laryngoplasty, swallowing evaluation, voice evaluation and voice therapy.

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the treatment Ultrasound for Throat Issues?

Ultrasound can improve patient satisfaction by speeding up diagnosis and reducing hospital stay time. It has also been used successfully to diagnose throat tumors and assess tonsil issues in children, showing its usefulness in throat-related conditions. ^{1 2 3 4 5}

Is ultrasound generally safe for humans?

Ultrasound, including its use with contrast agents, is generally considered safe for humans. Serious adverse reactions are rare, and any minor side effects like headache or nausea usually resolve on their own. It's important to use the lowest necessary settings to ensure safety. ^{6 7 8 9 10}

How does ultrasound treatment for throat issues differ from other treatments?

Ultrasound treatment for throat issues is unique because it is a non-invasive imaging technique that provides high-resolution images of the throat's structures, which can help in diagnosing and managing conditions without the need for more invasive procedures like endoscopy. This makes it particularly useful during situations like the SARS-CoV-2 pandemic, where reducing exposure to aerosol-generating procedures is important. ^{11 12 13 14 15}

Participant Groups

Group I: Vocal Cord Paresis Experimental Treatment 1 Intervention

Adult patients with vocal fold atrophy, paresis, or paralysis diagnosed at the Sean Parker Institute for the Voice who are planned to undergo injection laryngoplasty will be invited to take part in the study.

Group II: Vocal Cord Paralysis Experimental Treatment 1 Intervention

Adult patients with vocal fold atrophy, paresis, or paralysis diagnosed at the Sean Parker Institute for the Voice who are planned to undergo injection laryngoplasty will be invited to take part in the study.

Group III: Vocal Cord Atrophy Experimental Treatment 1 Intervention

Adult patients with vocal fold atrophy, paresis, or paralysis diagnosed at the Sean Parker Institute for the Voice who are planned to undergo injection laryngoplasty will be invited to take part in the study.

Group IV: Dysphonia Experimental Treatment 1 Intervention

Adult patients referred to the Sean Parker Institute for the Voice for voice assessment will undergo standard medical history including collection of age, gender, occupation, characteristics of voice complaints, and prior evaluation and treatments. Additionally, patients diagnosed with muscle tension dysphonia will be evaluated by ultrasound for the presence, size, and function of their suprahyoid musculature.

Group V: Dysphagia Experimental Treatment 1 Intervention

Adult patients referred to the Sean Parker Institute for the Voice for swallowing assessment will undergo standard medical history including collection of age, gender, occupation, characteristics of swallowing complaints, and prior evaluation and treatments. Adult patients without swallowing complaints will also be recruited to define normal anatomy and variation.

Group VI: Cough Experimental Treatment 1 Intervention

Adult patients who are seen at the Sean Parker Institute for the Voice and are determined to have neurogenic cough for which superior laryngeal nerve block is recommended will undergo this procedure under ultrasound guidance. Patients without neurogenic cough will also be recruited for ultrasound assessment to establish landmarks and normal variation.

Findings from Research

Patients who received bedside ultrasound (US) reported significantly higher satisfaction scores in overall emergency department care, diagnostic testing, and their perception of the emergency physician compared to those who did not receive US, based on a study of 70 patients over 10 months.

The use of bedside US not only expedited care and diagnosis but also enhanced the patient-physician relationship, highlighting its importance in improving patient satisfaction in healthcare settings.

This case highlights the successful use of oral administration of the ultrasound contrast agent SonoVue for diagnosing a pharyngoesophageal tumor in a patient with a cervical mass, which is a novel application not widely documented in medical literature.

The diagnosis was further validated through barium swallow imaging and an endoscopy-guided biopsy, demonstrating the efficacy of SonoVue in enhancing sonographic examination for better diagnostic accuracy.

Therapeutic ultrasound has been shown to significantly reduce pain intensity in patients with neck pain compared to sham or no treatment, based on a review of 12 randomized controlled trials involving 705 patients.

The safety profile of therapeutic ultrasound is favorable, as no adverse events were reported; however, its effectiveness when combined with other treatments for improving disability or quality of life remains unclear due to high variability in study results.

A survey of 105 members of the Italian National Society for Ultrasound revealed that while most physicians understand the bio-effects of ultrasound, only 50-60% correctly defined key safety terms like thermal index and mechanical index.

The results indicate a significant gap in knowledge regarding ultrasound safety, particularly concerning the mechanical index and its potential risks, highlighting the need for improved education and awareness among ultrasound practitioners.
