Brief summary

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.

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.

Interventions

DIAGNOSTIC_TESTUltrasonography imaging

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.
