Summary
Cervical ultrasound guides vocal fold injections for voice restoration, offering precise hyaluronic acid delivery. This method enhances accuracy and patient comfort compared to traditional techniques.
Area of Science:
- Otolaryngology
- Medical Ultrasound
- Voice Disorders
Background:
- Cervical ultrasound provides real-time imaging of laryngeal structures.
- This technique is being explored for its application in injection laryngoplasty within voice clinics.
Purpose of the Study:
- To describe the application of cervical ultrasound for guiding injection laryngoplasty.
- To evaluate the precision and safety of ultrasound-guided vocal fold injections.
Main Methods:
- Hyaluronic acid was infiltrated into the vocal fold.
- The injection procedure was performed under ultrasonographic guidance.
Main Results:
- Ultrasound allows precise needle placement within the vocal fold.
- Spatial relationships between the needle and surrounding structures are clearly visualized.
- Accurate material infiltration is achieved, superior to other methods.
Conclusions:
- Ultrasound-guided injection laryngoplasty offers accurate vocal fold augmentation.
- The technique avoids discomfort associated with the gag reflex from nasofibrolaryngoscopy.
- Potential challenges include calcified cartilages and patient cooperation, though no specific complications were observed.
