Near Infrared Spectroscopy in Thyroidectomy

February 15, 2021 updated by: Antalya Training and Research Hospital

The Effect of Vestibular Transoral Endoscopic Thyroidectomy on Cerebral Regional Oxygen Saturation: Comparison With Open Thyroidectomy

Thyroidectomy operations have traditionally been performed as open surgery. However, the scarring that occurs in the patient leads to cosmetic problems, especially in young women. Today, as a result of the development of minimally invasive surgical techniques, the number of natural orifice transluminal endoscopic surgeries (NOTES) is increasing. Surgical scars are avoided by using natural pathways such as the mouth, urethra, vagina or anus. Transoral endoscopic thyroidectomy (TOETVA) with vestibular approach, a form of NOTES, was first performed in 2011. In this method, the operation is performed through three ports entered near the gingiva-buccal sulcus. TOETVA surgeries are performed with an insufflation pressure of 6 mmHg in the neck region. No studies are examining the effects of this pressure on the blood vessels in the neck region on the blood supply to the brain tissue. Therefore, the investigators aim to compare cases operated using open thyroidectomy or TOETVA method by measuring cerebral regional tissue saturation.

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.

TOETVA
The demographic data of the patients undergoing TOETVA surgery will be recorded. Then, blood pressure, pulse pressure, pulse oximeter, end-tidal carbon dioxide, right and left cerebral regional oxygen values in the operation room will be recorded at certain intervals. It will also be recorded if complications develop.
Device: Near-infrared spectroscopy
The Near-infrared spectroscopy probes will be placed in the frontal region.
Open thyroidectomy
The demographic data of the patients undergoing open thyroidectomy surgery will be recorded. Then, blood pressure, pulse pressure, pulse oximeter, end-tidal carbon dioxide, right and left cerebral regional oxygen values in the operation room will be recorded at certain intervals. It will also be recorded if complications develop.
Device: Near-infrared spectroscopy
The Near-infrared spectroscopy probes will be placed in the frontal region.
