The importance of a mouth gag that can be securely held by the same assistant who holds the head is realized by laryngologists, who all, at times, must work in the throat of unanesthetized children for various purposes, such as palpation for retropharyngeal abscess, palpation for adenoids, intubation and bronchoscopy. Self-retaining mouth gags, useful in anesthetized patients, are not satisfactory for this purpose.

The thimble idea, original with Dr. John W. Boyce, presents many advantages, but the thimbles so far devised are not easily kept in position by most men without encroaching so much on the relatively small oral cavity of children as to interfere with the operator.

The instrument is made of brass, the lines of the old bite block being followed as far as the alveolar wedge is concerned, but in the child's size the width is decreased so that the block encroaches less on the oral cavity.
