Area of Science:

Neuroscience
Anatomy

Background:

Electromyographic (EMG) recordings of the lateral pterygoid muscle (LP) are challenging due to risks of damaging nearby structures like the maxillary artery and long buccal nerve.
Orofacial pain patients often experience pain and reduced jaw mobility, complicating EMG electrode placement.

Purpose of the Study:

To develop a dependable intraoral technique for placing electrodes in the inferior head of the lateral pterygoid (IHLP).
To minimize jaw displacement during electrode placement for improved EMG recordings.

Main Methods:

A novel intraoral needle insertion technique was developed and tested on cadavers and human subjects.
Electrodes were inserted through the mucosa near the maxillary second molar, targeting the IHLP midportion.

Placement accuracy was confirmed using computed tomography (CT) and electromyography (EMG).

Main Results:

The optimal insertion depth for accurate IHLP electrode placement was determined to be 29 mm.
The technique successfully avoided critical anatomical structures, including the maxillary artery and long buccal nerve.

Conclusions:

The described intraoral technique offers a reliable and safe method for IHLP electrode placement.
This approach is particularly beneficial for patients with impaired jaw function, reducing the risk of complications.
