Temporary noncicatricial focal alopecia following Gamma knife radiosurgery: Case series and review of literature
Conclusion: Compared to whole brain radiotherapy, chances of alopecia are significantly less after GKRS. Despite a sharp dose fallout, a single fraction high-dose radiosurgery with GKRS may expose the skin appendages to more than 3 Gy radiation exposures, which may injure the hair follicles irrespective of the growth phase (anagen, telogen, or catagen) they are in. A careful planning that includes sparing of the dermal appendages and hair roots up to 4–6 mm depth in the skin may prevent this complication. Patients with superficial lesions should be well informed about the reversible nature of this possible complication, with near-normal hair growth being established within 2 months of treatment.
