An implanted tongue septum fascia retraction device includes a fascia fixer, a pull line and a mandible fixer. The fascia fixer is fixed to a tongue septum fascia by means of a fixing clamp, a fixing hook or a fixing ring, and the mandible fixer is fixed to a mandible. One end of the pull line is connected to the fascia fixer, and the other end of the pull line is fixed to the mandible fixer. By adjusting the tightness of a pull line, a tongue septum fascia may be retracted forwards, thus pulling a falling tongue base forwards, opening an obstructed upper airway, and fulfilling the aim of treating snoring and obstructive sleep apnea/hypopnea syndrome (OSA) caused by glossoptosis.
