The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on soft-palate implants for simple snoring.

The guidance was considered for reassessment in November 2010 and it was concluded that NICE will not be updating this guidance at this stage. However, if you believe there is new evidence which should warrant a review of our guidance, please contact us via the email address below.


Simple snoring is part of a spectrum of breathing disturbance during sleep. This overview relates only to patients who snore but do not experience apnoea or hypopnoea episodes. NICE is also preparing separate interventional procedures guidance on the use of soft-palate implants for obstructive sleep apnoea (IP404).

The muscles around the upper airway relax during sleep. A narrowed airway can lead to air turbulence, which causes vibration in soft tissues of the oropharynx, generating the snoring sound during inspiration. The specific origin of the noise varies between individuals, and may include the soft palate. Snoring may disturb the sleep of the patient and their bed partner, and affect relationships. This procedure may be used for patients with problematic snoring where the soft palate is implicated, and when snoring has not been improved by conservative treatment.

The procedure is usually performed under local anaesthesia. A hollow introducer needle containing the implant is used to pierce the soft palate, close to the junction with the hard palate, reaching into the muscle layer. The needle is then withdrawn, leaving the implant in position. Typically two or three implants are inserted in a single procedure, at the midline of the soft palate or parallel to it. The aim of the procedure is to stiffen the soft palate over subsequent weeks as a result of fibrosis.
