Sclerotherapy (Scarless Surgery)

We use Sclerotherapy to treat mainly the Vascular Malformations (Congenital Abnormally Formed Blood Vessels). However, recently, we are using it to treat other Cystic Lesions (fluid filled sac causing a swelling or bulge) as well.

The Vascular Malformation includes:

Lymphatic Malformation 
(Congenital Abnormal Lymphatic Vessels that Do Not Connect to a Main Branch and Ends Blindly, Forming a Cyst of Lymphatic Fluid. Macrocystic means one or two large cysts while Microcystic means many small cysts)
(Congenital Abnormal Veins that Do Not Drain Blood Effectively But Pools Blood and Dilates Over Time)

(Congenital Abnormal Connection Between Arteries and Veins, Without Any Capillaries in Between. The Direct High Pressure from Arteries is Transmitted to the Veins Causing Them to Engorge and Dilate With Arterial Blood, Over Time)

Plunging Ranula: One of Other Cystic Lesions Treated by Sclerotherapy, Recently.
(Cysts Forming as a Result of Blocked Salivary Gland Ducts and Extending into the Neck, from the Mouth)

Sclerotherapy is a method whereby agents that irritate the vessel walls are injected to cause the vessels to harden & obliterate over time. Thus, cutting off the blood supply to the diseased part to cure it. This technique is done through an injection needle, therefore no scar is left on the skin & there is less complications such as blood loss & the recovery time is short.

Sclerotherapy is used to treat:
1. cystic lesions (fluid filled swellings)
2. vascular malformations & hemangiomas (swellings that are composed of blood vessels)
3. uncontrollable bleeding sites after trauma or surgery
4. cancers (to cut off blood supply to tumors)
5. to cut off nerve supply to control abnormal muscle movements or excessive pain
6. hemorrhoids (anal swellings that are composed of veins)

Dr. Mol is the only person in PNG specializing in the art & technique of sclerotherapy. He has obtained a PhD on sclerotherapy while studying plastic surgery at Hokkaido University, Japan. He has elucidated the mechanism of action (how they work or induce sclerosis) of 3 commonly used sclerosants (agents that induce sclerosis or hardening of vessels).

We are now extending our Sclerotherapy technique to treat Mandibular Bone Cysts.
