Preauricular sinuses in the pediatric population: Techniques and recurrence rates

Dilemma in Diagnosis-Huge Preauricular Sinus Mimicking Parotid Tumor

“…Robert J et al reported a new inside-out technique for excision of preauricular sinus where no recurrence was noted [5]. Gan EC et al reported a low recurrence rate of 2.4% by performing excision of preauricular sinus under microscope guidance and under methylene blue and probe guidance [4]. From our literature review, there were no reported cases of preauricular sinus presenting as parotid swelling.…”

“…Incomplete excision of sinus tract leads to recurrence of preauricular sinus. Recurrence rate ranged from 22 to 42% has been reported in cases where preauricular sinus is excised with traditional method without any aid for tract delineation or visualisation [4]. Robert J et al reported a new inside-out technique for excision of preauricular sinus where no recurrence was noted [5].…”

A systematic review on the surgical outcome of preauricular sinus excision techniques

“…Overall DoE was H in 17 studies (Table ). Twenty‐two studies scoring M and five studies scoring L DoE were excluded.…”

“…No study contained L RoB; four studies had a M; and all included studies had a H RoB (Table ). We included 14 studies containing H DoE and H RoB (Table).…”

“…Preauricular sinuses are common benign congenital malformations of preauricular soft tissue . Most commonly seen in the African American and Asian populations, it is estimated that disease occurs in 0.1% to 0.9% Western populations . The majority of preauricular sinuses present asymptomatically, therefore not requiring treatment.…”
