Glossectomy refers to surgical removal of part or all the tongue.

There are several approaches to performing a glossectomy, most commonly transorally (through the mouth) for smaller and shallower tumors. Larger tumors or those with significant depth may require resection of the lower lip and mandible ("lip-split mandibulotomy"), or opening the sublingual or submental compartments for improved visualization of the inferior tongue ("transcervical pull-through"). Neck dissection and reconstruction can be performed for all glossectomy procedures.<ref name=":0" />

Glossectomy refers to the surgical removal of part or all the tongue. It is primarily performed for excision of malignant lesions in addition to benign neoplasms of the tongue, obstructive sleep apnea, and macroglossia. Excisional or incisional biopsies of tongue lesions of undetermined etiology are also performed.[1]

There are several approaches to performing a glossectomy, most commonly transorally (through the mouth) for smaller and shallower tumors. Larger tumors or those with significant depth may require resection of the lower lip and mandible ("lip-split mandibulotomy"), or opening the sublingual or submental compartments for improved visualization of the inferior tongue ("transcervical pull-through"). Neck dissection and flap reconstruction may be performed for glossectomy procedures.[1]

Preoperative management

Patient evaluation

System Considerations
Neurologic Consider stroke risk if smoking history, tongue direction if prior surgeries or hypoglossal nerve involvement
Cardiovascular Consider CAD/vascular disease/HTN if smoking history
Pulmonary Assess compliance of airway including neck mobility, mouth opening, presence of trismus, tongue fixation / mass obstruction of the airway. Check patency of each nare. Consider pulmonary pathology related to smoking history. Consider OSA and possible related pulmonary hypertension
Gastrointestinal Assess for dysphagia/GERD
Hematologic Consider DVT risk if smoking/cancer history
Other Consider history of alcohol abuse in head and neck cancers, assess nutritional status

Labs and studies

  • Head CT/MRI

Operating room setup

  • Supplemental equipment for a possible difficult airway including video laryngoscope, fiberoptic, high flow nasal cannula, equipment for surgical airway[2]
  • If oral intubation, reinforced ETT and bite block recommended[3]
  • Assistance should be immediately available during induction

Patient preparation and premedication

  • Consider endoscopic or laryngoscopic airway exam to assess tumor extension[2]
  • Consider acetaminophen 500-1000 mg PO as part of multimodal regimen

Monitoring and access

  • Standard monitors, PIV
  • Mouth gags/lip retractors per surgeon

Induction and airway management

  • Standard premedication
  • Administration of antisialogogue (glycopyrrolate) may improve operating conditions[3]
  • Decreased compliance due to neck radiation is the most significant predictor of difficult mask ventilation[4]

  • Nasal intubation may be required depending on tumor location (e.g. side versus base of tongue) and surgeon preference
  • Consider awake fiberoptic intubation if large tumor at the tongue base

  • Assess degree of upper airway obstruction prior to extubation
    • Reintubation may be impossible if obstruction occurs
  • Smooth extubation important if skin graft used for closure
    • Graft hematomas are the primary cause of skin graft failure[6]
  • Extubate after recovery of protective airway reflexes
