Coblation® Radiofrequency Palatoplasty

This device & technique allows the surgeon more scope in correcting the precise palatal abnormalities which are responsible for snoring. This includes laxity of the soft palatal tissue, thickness of the palate, bulky tonsils.

The procedure consists of anaesthetising the palate with a combination of anaesthetic spray and injections, similar to that employed by dentists. Then, a radiofrequency hand-piece is used to incise the palate in two areas and to remove some of the Uvula, which hangs at the back of the throat. Once anaesthetised, the patient feels no pain, although awake. Then, “channels” of radiofrequency shrinkage are produced in the palate (and tonsils, if appropriate) to reduce the bulk of these structures. Sometimes, “webbing” must be removed from the lower edge of the palate too, as this holds it in a downward position, and may restrict improvement of the snoring.

The procedure takes about 30 minutes to perform. It is not necessary to fast before the procedure but patients should not drive, or use public transport home. Painkillers are prescribed and should be used regularly until the pain subsides. This operation is painful, although not as painful as a Laser / Diathermy Assisted Uvulo-Palatoplasty (LAUP/DAUP) and takes about a week to 10 days to recover. The voice is not affected, but swallowing is painful during the recovery period. An odd sensation in the throat may be
present for some weeks afterwards, due to anatomic alteration. Time off work will be required, usually about 1 week. Snoring resolves over a 4-6 week period, as tissue shrinkage and scarring occur.

The success rate of this procedure is approximately 70%, although patients may begin snoring again in the event of weight gain, excess alcohol intake or in old age. This operation may be repeated, or combined with other anti-snoring treatments. “Success” is defined as total abolition of snoring or a marked reduction, such that the partner’s sleep is no longer disturbed.
