Where Surgeons Collaborate with Physicians

Tailored Sleep Apnoea Surgery, CPAP, Mouth Guards and Combination Therapy in the Mornington Peninsula.

CSSC Mornington

CSSC Mornington is a advanced sleep clinic where sleep surgeons collaborate with sleep physicians to bring you sleep solutions. We offer Sleep Apnoea treatments that combines the most proven Advanced Sleep Surgery, 3D Printed Mouth Guards, CPAP and a combination of methods customised to bring you the very best.


If you book to be seen in the CSSC clinic, you will be seen by two specialists. Those referred by a Sleep Physician will be seen by our Sleep Surgeon alone, who will collaborate with your Sleep Doctor to formulate a treatment plan. Mr Nalaka De Silva, an Ear Nose and Throat Surgeon specialising in Sleep Apnoea Surgery and Dr Juan Mulder, a Respiratory Physician, a registered Polysomnographic and a member of the thoracic society of Australia, have worked together since founding CSSC Mornington, Melbourne in 2018.

Due to the unique collaboration and research between surgeon and physician, CSSC has delivered outstanding results to sleep apnoea patients in Melbourne. We have observed that 90% of those operated by CSSC Mornington have avoided a CPAP Machine and 85% of non operated patients have successfully managed their sleep apnoea. CSSC Mornington has presented their results at the National Surgical Conferences (ASOHNS: 2020-presentation, 2019-poster). (view links for further details and discussion of our results).



CSSC is a unique multidisciplinary clinic to help patient with sleep disorders.


Our team will help you organise a sleep study before your visit us. A sleep study will enable us to get the best objective measurement of your sleep.If you have sleep apnoea, you may be seen at the Combined Sleep Clinic (CSSC). If you are already seeing a physician and require our input, we may get you assessed by our sleep surgeon alone.


At CSSC you will be seen by two doctors, sleep-surgeon and sleep-physician. Before the consultation, the doctors will have a close review of your sleep study. They will look at the number of events, the severity of events and oxygen levels and the sleep architecture in detail. During your consultation, the doctors will have an open discussion about what you or your partner notices at night, daytime symptoms and resultant medical concerns. We will understand the impact on work and social wellbeing. After that, both doctors will carefully assess your airway with endoscopy. The airway will be graded, and sites of collapse documented. Finally, we will use our algorithm to see if you have favourable anatomy for surgery.


At the end of the comprehensive assessment, doctors will have a very good understanding of your condition, sleep physiology, and sites of airway collapse. We will take into account your wishes. The basic rules are as follows.


1) If you have favourable anatomy for surgery, and you wish for surgery, this will be planned. The likely success rates will be discussed. 

2) If you have less favourable anatomy for surgery, we will request CPAP trial first. If CPAP fails, surgery will be offered. We have found even patients with challenging anatomy achieving success regularly with our modern surgery. Some may need combination therapy, which is surgery plus positional device, weight loss or MAS (Mouth Guard).

3) Previous Tonsillectomy patients are encouraged not to undergo surgery as often the scar tissue prevents sufficient elevation of palate and expansion of the airway. With education, most such patients often are happy to using a CPAP. Combination therapy (surgery and MAS) can help those who are intolerant of CPAP.

4) Those with mild sleep apnoea with severe snoring will be first trialled on CPAP. If CPAP makes them feel refreshed, surgery can benefit and can be a possible treatment option. Those who wish surgery for snoring alone will be offered surgery, if there are significant social concerns. 

Surgery we offer is unique and encompass some of the best aspects of trilled and tested Australian techniques and European techniques. We have researched over the last 3 years to fine-tune and get the best possible results.
