About this study
Official title: Is it Possible That Direct Rigid Laryngoscope-related Ischemia-Reperfusion Injury Occurs in the Tongue During Suspension Laryngoscopy as Detected by Ultrasonography: A Prospective Controlled Study
This study aimed to detect tongue edema associated with the pressure exerted by a rigid direct laryngoscope by measuring the tongue area using USG in patients undergoing suspension laryngoscopy (SL) procedures.
Read the detailed description
Suspension laryngoscopy (SL) is a surgical procedure for both diagnostic and therapeutic purposes. In this procedure, a rigid direct laryngoscope is inserted orally, and the tongue and the base of the tongue are compressed.The tongue is an ideal organ for evaluation with ultrasonography. This study aimed to detect the occurrence of tongue edema through ultrasonography examination due to the rigid direct laryngoscope in SL procedures.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Ultrasonography imagingDiagnostic test
This study aimed to evaluate the tongue areas and compare the tongue areas before the implementation of rigid direct laryngoscope and after the rigid direct laryngoscope.
| Study group | Role | What they receive |
|---|---|---|
| Study | The first group is the study group. Patients aged 20 years or older and were to undergo suspension laryngoscopy procedure were eligible for inclusion in this group. Tongue areas were measured twice by submental USG. The first measurements (TA1) were done immediately after endotracheal intubation before introducing the rigid direct laryngoscope, whereas the second measurements (TA2) were done after the SL procedure and after removing the rigid direct laryngoscope just before extubation.The difference between TA2 and TA1 (i.e., TA2-TA1) were used to define the occurrence of tongue edema as study group. Receives: Diagnostic Test: Ultrasonography imaging | |
| Control | The second group was the control group, which included patients who did not need SL and any head and neck procedures.The tongue areas of these patients were measured twice by submental USG as in the study group. The TA1 measurements were done immediately after endotracheal intubation, whereas the TA2 measurements were done at the end of the surgical procedure just before extubation. The difference between TA2 and TA1 (i.e., TA2-TA1) were used to define the occurrence of tongue edema as study group. Receives: Diagnostic Test: Ultrasonography imaging |
What is being measured
