Birthmark Removal Surgery Facts
Birthmarks are skin surface irregularity and altered coloured changes that is immediately present after birth, or appears shortly after birth. Birthmarks are generally categorised into two groups. Pigmented and vascular birthmarks. Pigmented birthmarks include congenital moles, cafe au lait macule, Mongoloid spots and Nevus of Ota. Vascular birthmarks include salmon patch, cherry haemangiomas and port wine stain. Nowadays, advances in technology has allowed birthmark removal surgery to be carried out safely and effectively across all skin types.
Why do people get birthmarks?
There is no good answer to this question at the moment. While some birthmark can run in families, most occur as result of a random occurrence.
Thankfully most birthmarks are harmless and do not pose any dangers to health. However, certain birthmarks may be associated with a underlying genetic disorder or medical condition. In fact, newborns with the giant congenital moles are at risk of skin cancer, and must be monitored closely.
Cafe au lait Macule (CALM)
A common birthmark is the Café au lait spot. Café au lait spots take on a coffee with milk hue (very much like the ‘Kopi’ we order here in Singapore), hence the name. It should probably be called Kopi spots in the Singapore context. Café au lait birthmarks are brown and flat with varying sizes, sometimes growing as large as 10cm!
While most Café au lait spots are harmless, multiple café au lait spots and those with other skin changes may lead your doctor to suspect an underlying genetic disorder such as Neurofibromatosis or Tuberous Sclerosis.
Birthmark removal surgery with lasers are effective and safe in all skin types.
The Pigment Focus Laser treatment can be used to treat Café au lait spots. CALM birthmarks are known to recur after laser, and may require repeated treatments.
Nevus of Ota
First described by Japanese doctors in 1939, the Nevus of Ota birthmark appears as a blue or grey patch and is more common in Asians. It commonly involves one side of the face, temple and forehead. The eye and inner lining of the mouth may also appear to be pigmented in some cases. While the underlying cause is unknown, this birthmark appears along the distribution of the nerves of the face, and tends to get darker with the passage of time. Individuals with Nevus of Ota are at risk of glaucoma, a condition where pressure builds up within the eyes, and should therefore get their eyes checked regularly.
As this birthmark resides deeper into the dermal layer of the skin, topical lightening creams are not effective. The Pigment Focus Laser for birthmark removal surgery is a first line treatment. Laser removal for Nevus of Ota work by selectively destroy the pigment producing cells lying within the skin. The treatment delivers good results and minimal scarring after 4-8 laser sessions. With modern day advanced laser technology, more than 90% of the pigmentation is cleared, and scarring rate is minimal.
