A Heister mouth gag is a surgical instrument used in dentistry and oral surgery to keep the mouth open, providing an unobstructed view and access to the surgical area during procedures under anesthesia, such as oral surgeries, tonsillectomies, and maxillofacial surgeries. Its adjustable, screw-based mechanism allows surgeons to control the degree of mouth opening, ensuring patient safety and enabling precise surgical manipulation.

Oral and Maxillofacial Surgery:

The primary function is to provide a clear surgical field by keeping the mouth open.

Procedures in the Mouth and Throat:

Used for various procedures and surgeries in the mouth and throat area, including tonsillectomies and adenoidectomies.

Trauma Cases:
