Boyle Davis Mouth Gag

This instrument is part of the tonsillectomy set.

Mouth gags are used to keep the patient’s mouth open during oral surgery, leaving both hands of the surgeon free to operate.

The Boyle Davis mouth gag consists of the Davis gag, a frame that serves to hold the mouth open and the Boyle tongue depressor to hold the tongue down. The tongue depressor comes in several sizes, from pediatric to adult. The instrument is assembled by sliding the tongue blade into the frame. The mouth gag is held in position using the Draffin bipod stand.

This is a picture of the Draffin's bipod stand. These two rods are used to hold the mouth gag.


Used in oral and oropharyngeal surgeries.
  • Adenoidectomy
  • Tonsillectomy
  • UPPP and other procedures on the soft palate
  • Procedures on the hard palate like cyst or tumour excision

More information

  • It cannot be used to perform procedures on the tongue as it is completely held down by the tongue blade.
  • This instrument can cause injury to the lips and teeth. Care must be taken while applying the mouth gag to avoid getting the lips caught in it.
  • Opening the mouth excessively with the gag can cause dislocation of the temporomandibular joint.
