A 38-year-old woman with a recurrent suppurative pilonidal cyst was successfully treated causally with an Nd-YAG (neodymium-doped yttrium aluminium garnet) laser, and with no recurrence at 3-month follow-up. A similar success was observed for another 15 consecutively treated patients, including suppurative cases. The effect could be attributable to the ability of the YAG laser to operate at a wavelength of 1064 nm and to penetrate the skin to levels deeper than that of most other lasers before the energy is absorbed in melanin and oxyhaemoglobin. Consequently, the contents of the cyst can be reached and destroyed. The treatment could be a very attractive alternative to open surgery.
一名38岁复发性化脓性藏毛囊肿女性患者通过钕钇铝石榴石（Nd-YAG）激光进行病因治疗取得成功，3个月随访无复发。另外15例包括化脓性病例的连续治疗患者也取得了类似成功。这种效果可能归因于YAG激光能够在1064 nm波长下运行，并在能量被黑色素和氧合血红蛋白吸收之前穿透皮肤至比大多数其他激光更深的层次。因此，可以到达并破坏囊肿内容物。该治疗可能是开放手术非常有吸引力的替代方案。
