Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Laser hair removal treatment
Patients who choose to enroll will plan to undergo a total of up to 8 laser hair removal sessions every 4-6 weeks. If patients develop abscess or infection during this time, they will undergo I\&D and/or antibiotics, consistent with standard therapy for infection or abscess. If patients have 2 or more infections in 1 year, pain or drainage for more than 1 month, or miss more than 1 week of school or work due to ineffective treatment of pilonidal disease, these patients will undergo surgical excision and subsequent follow-up at surgeon's discretion. Patients will follow up at 2-4-week intervals for 3 months, then at 6, 9, and 18 months after conclusion of the laser therapy sessions. At all follow-up sessions, patients will be given the DQLI, CDQLI, and Promis 3A Pain survey. Unscheduled visits such as unplanned clinic visits, emergency department encounters, and hospitalizations, will be included in data collected for analysis of primary and secondary outcomes.
Laser hair removal
Those who consent to participate in the study will be treated with up to 8 sessions of laser hair removal utilizing a long-pulsed laser to the natal cleft at treatment intervals of 4-6 weeks.
