Base of Tongue Handpieces

Olympus Somnoplasty offers two different handpieces for base-of-tongue procedures. The dual-channel radio-frequency handpiece is designed to create predictable dual-site lesions. The single-channel radio-frequency handpiece is designed for creation of single-site lesions.

Key Benefits

  • This device is indicated for the reduction of the tongue base component in Sleep-disordered Breathing (OSA). 
  • Typical treatment zone is 2.5 – 3.0 cm by 2.5 – 3.0 cm in the midline and circumscribes the circumvallate papilla. Avoid being too lateral. 
  • Bend electrode as you approach more posteriorly in order to maintain the lesion at its proper depth (2 cm into the genioglossus muscle). 
  • Saline injection at the site of lesion may improve tissue volume reduction.

Patient Selection

  • Appropriate evaluation for Sleep-disordered Breathing, fiberoptic laryngoscopy, cephalometric x-rays, a sleep study and responses to validated questionnaire are recommended for diagnosis or patient selection.
  • It has been shown that this procedure can be performed alone or in conjunction with other procedures such as UPPP and/or nasal surgery.
