Whitehead Mouth Gag — Manchester-Pattern Glossectomy

Whitehead Mouth Gag — Manchester Glossectomy Pattern

Walter Whitehead (1840-1913), surgeon at the Manchester Royal Infirmary and originator of the Whitehead glossectomy procedure for tongue cancer (the technique of total tongue removal he published in 1891), designed his mouth gag for the wide oral exposure his operations required. The Whitehead opens the mouth to approximately 60 mm interincisal distance with side-arm retraction holding the cheek out of the surgical field — the working space needed for transoral tongue surgery before pharyngeal-and-laryngeal endoscopy made smaller-aperture access viable.

The Whitehead glossectomy era

Before radiotherapy and chemotherapy options, surgical excision was the only treatment for oral-cavity cancer; Whitehead’s glossectomy gave selected patients five-year survival rates above 30%, a remarkable outcome for the era. The mouth gag was the instrument by which the operation could be performed at all — the wide aperture brought the posterior tongue into view for the operator working from outside the mouth.

Modern survival

The Whitehead mouth gag remains in use for transoral robotic surgery (TORS) port placement, for transoral resection of base-of-tongue tumours, and for cleft-palate repair in the older paediatric patient where a Dingman retractor would be undersized.
