This study examines the impact of intraoperative recurrent laryngeal nerve monitoring signal changes on the postoperative voice quality of thyroid surgery patients. By analyzing extensive surgical data and postoperative voice recordings, the investigation seeks to identify patterns in the variations of these signals and their correlation with voice quality outcomes. The goal is to enhance clinical understanding and surgical practices, allowing for more precise assessments of nerve function, informed surgical interventions, and improved postoperative patient well-being.
Age 20-60 years old.
Planned conventional unilateral thyroid lobectomy + isthmus resection + central compartment lymph node dissection.
History of past head and neck surgeries.
Pronunciation system defect and disorder history.
History of vocal cord polyps or nodules.
History of upper respiratory tract infection in the 2 weeks before surgery or postoperative infection history.
People with thyroid cancer who are planned to undergo traditional surgical treatment.
Cohort
Prospective
Traditional thyroid surgery.
Procedure/SurgeryThe patient undergoes traditional thyroid surgery with concurrent intraoperative nerve monitoring technology.
Intraoperative electromyographic signals.
Recording intraoperative electromyographic signals, including vagus nerve V1 and V2 signals, recurrent laryngeal nerve R1 and R2 signals.
Voice analysis data(SPL)
Recording data(SPL) of voice tests before and after the surgery, sound pressure level in dB(A)
Voice analysis data(F0)
Recording data(F0) of voice tests before and after the surgery, F0 in Hz
Voice analysis data(Jitter)
Recording data(Jitter) of voice tests before and after the surgery, Jitter in percentage
RBH
Conducted by an otolaryngologist, the RBH assessment includes R (Roughness), B (Breathiness), and H (Hoarseness).
VHI-30
Voice Handicap Index, including a scale with 30 items.The full, non-abbreviated title of the VHI-30 scale is the "Voice Handicap Index-30," and it is translated as the "Voice Disorder Severity Index." The scale ranges from a minimum score of 0 to a maximum of 120, with higher scores indicating poorer outcomes.
Neural Width
Recorded width of the recurrent laryngeal nerve in millimeters.
Is there branching
Note if the recurrent laryngeal nerve branches.
