Larynx01:21

Larynx

6.2K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

    Summary

    Robotic thyroidectomy offers better long-term voice function recovery compared to conventional methods. Patients undergoing robotic procedures showed improved voice symptoms and acoustic measures up to two years post-surgery.

    Area of Science:

    • Endocrinology
    • Surgical Oncology
    • Otolaryngology

    Background:

    • Thyroidectomy is a common procedure for thyroid nodules.
    • Voice function is a critical concern for patients undergoing thyroid surgery.
    • Conventional transcervical thyroidectomy can impact long-term voice quality.

    Purpose of the Study:

    • To compare long-term voice function after robotic thyroidectomy versus conventional thyroidectomy.
    • To evaluate subjective and objective voice parameters in both surgical groups.

    Main Methods:

    • Prospective evaluation of voice function in 54 robotic and 70 conventional thyroidectomy patients.
    • Assessment of subjective voice symptom score (VSS) via questionnaires at multiple time points (pre-op, 3, 6, 12, 24 months).
    • Objective acoustic analysis including fundamental frequency, jitter, shimmer, noise-to-harmonic ratio, highest frequency, frequency and intensity range, and maximal phonation time.

    Main Results:

    • Robotic thyroidectomy group showed better VSS at 3 months and recovery to pre-operative levels by 2 years, unlike the conventional group.
    • The robotic group exhibited significantly wider phonatory frequency range and higher highest frequency at 6, 12, and 24 months post-surgery.
    • Acoustic parameters in the robotic group recovered to pre-operative levels by 6 months, while remaining below pre-operative levels in the conventional group at 2 years.

    Conclusions:

    • Robotic thyroidectomy demonstrates superior outcomes in voice symptom recovery up to 2 years post-operatively.
    • Acoustic parameters related to voice quality show significant advantages with robotic thyroidectomy compared to conventional methods.
    • Robotic thyroidectomy is a viable alternative for preserving and improving long-term voice function.
