Neurolaryngology integrates neurological insights with laryngology, using laryngeal electromyography (LEMG) as a key tool for diagnosing and predicting vocal fold paralysis and other laryngeal conditions.
Area of Science:
- Neurolaryngology
- Laryngeal Electromyography
- Neuromuscular Diseases
Background:
- Neurolaryngology combines neurological and laryngological expertise for neuromuscular laryngeal disorders.
- Laryngeal electromyography (LEMG) is a crucial diagnostic and prognostic tool in this field.
- LEMG applications have expanded to include all accessible laryngeal muscles beyond the thyroarytenoid.
Purpose of the Study:
- To highlight the significance and applications of laryngeal electromyography (LEMG) in neurolaryngology.
- To discuss the role of LEMG in assessing vocal fold paralysis and related neurological conditions.
- To explore the prognostic capabilities of LEMG in differentiating nerve lesions and mechanical fixations.
Main Methods:
- Standardized protocol for performing and interpreting laryngeal electromyography (LEMG).
- Diagnostic electrostimulation combined with LEMG.
- Application of LEMG for needle guidance in botulinum toxin injections and augmentation laryngoplasty.
- Utilizing diagnostic neurostimulation to assess vocal fold motor potential.
Main Results:
- LEMG confirms, localizes, and prognosticates vocal fold paralysis.
- LEMG differentiates acute from chronic recurrent laryngeal nerve lesions and mechanical fixation.
- LEMG and ultrasound can guide interventions for spasmodic dysphonia and laryngoplasty.
- Neurostimulation identifies candidates for laryngeal pacemakers.
Conclusions:
- Laryngeal electromyography is indispensable in neurolaryngology for diagnosis and prognosis of vocal fold dysfunction.
- LEMG aids in treatment timing and patient selection for various laryngeal surgeries.
- Neurolaryngology addresses diverse conditions including spasmodic dysphonia, stroke, and Parkinson's disease affecting the larynx.

Larynx
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,...

Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...
