  • Once infected, preauricular sinuses rarely remain asymptomatic, giving rise to recurrent infections, cellulitis, or even abscess formation, a collection of pus that needs to be lanced.[subent.com]
  • Tracts arising from (Type I) or paralleling (Type II) the external auditory canal can lead to a cystic cavity, which will become recurrently infected and often drain in or near the ear.[ghorayeb.com]
  • Recurrent infection is a clear indication for complete excision and provides the only definitive cure. Recurrence rates after surgery range from 9% to 42%. Meticulous excision by an experienced head and neck surgeon minimizes the risk of recurrence.[onlinelibrary.wiley.com]
  • Recurrent infection is an indication for surgical excision of the pit and sinus tract.[visualdx.com]
Surgical Procedure

Prevention

  • 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]
  • Surgery to remove the pit involves removal of the pit, the entire tract, a small amount of surrounding skin, and the underlying tissue to prevent recurrence of the pit.[entforchildren.net]
  • 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]
  • If the lesion is symptomatic, then resection of the entire sinus tract — possibly including a portion of cartilage and sometimes requiring a flap — is required to prevent recurrence and complications. 1 If there are no other anomalies aside from the preauricular[mdmag.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]
