Non-Invasive Treatment of Bromidrosis

by Frequency-Doubled Q-Switched Nd:YAG Laser

 

Bromidrosis, or osmidrosis is a very common disorder that is most obvious in tropical environments such as Thailand. In this climate, axillary bromidrosis, the unpleasant odor given of by the axillary area as one perspires, is the most common concern. Though antiperspirants had been available and affordable for the longest time, they only provide temporary relief. There is also an invasive surgical approach that had seen so many complications to be worth the try for this concern, hence, the researchers thought of using laser therapy as an alternative treatment for bromidrosis.

Thirty two (32) female patients aged 15-45 with a mean age of 30 years were elected as subjects to the study. Twenty five (25) of the subjects have Fizpatrick Type 3 skin tone while the other 7 have type 4. Since all the subjects had been using topical antiperspirants for some time prior to surgery, all subjects have varying degree of hyperpigmentation on the area.

The laser system used in the study was a frequency doubled Q-Switched Nd YAG Laser with a wavelength of 532 nm, and a pulse duration of 25nm. The unit emits a maximum fluence of 3.5 to 14 joules/cm2at 4 and 2mm spot size. The lasing pattern was spot by spot in a continuous row, allowing 30% overlapping between spots.

Immediately after laser impaction, the treated area suddenly turned white, then bright red and a bit swollen. Patients reported stinging sensation despite the topical anesthesia that was applied prior to treatment. A few days after the treatment, the treated area formed a confluent bleb with a thin layer of reddish-brown fluid collecting underneath the epithelium. A thin scab also formed in most of the patients during the first 7 days after the procedure. Complete re-coloration took a few months for the subjects with darker skin tone.

As a result of the treatment, Twenty-six (81.2%) of the patients reported good to excellent results, 4 (12.5%) reported fair, and 2 (6.5%) reported poor results. No scar formation or change in skin texture was noted and discoloration was temporary for all the patients.
