Identification of the exact anatomical location of sinus tract is necessary because total excision of the lesions including those tracts is the only way to prevent recurrence. [synapse.koreamed.org]

Therefore, the routine removal of a small portion of perichondrium and/or auricular cartilage along with the sinus tract may yield a more thorough excision and help to prevent recurrence. [jamanetwork.com]

Neurosurgeons must be aware of this rare condition and must opt for complete excision to prevent infectious sequelae even if the preauricular sinus is asymptomatic. [journals.lww.com]

It was previously recommended to remove all these preauricular cysts preventively before any symptoms develop. Newer thinking recommends such procedures only in symptomatic patients. [newyorkentspecialist.com]
