The Prevalence of Preauricular Sinus and Associated Factors in a Nationwide Population-Based Survey of South Korea

Abstract

A large-scale government-centered survey demonstrates a high prevalence, female dominance, and age-related decrease of PAS in South Korea.

Preauricular sinus: Incidence and inheritance

“…The reported incidence figures in our study are similar to others reported in European and Caucasian populations, somewhat underlining the genetic predispositions on inheritance, as the reported figures in Asian and African populations are significantly higher (11,14,20,22).…”

“…A structure was considered a PAuS when present in the region of the crus of the auricular helix as a preexisting dent, dimple or foramen, not due to an ear piercing, other cosmetic or medical procedures. The set criteria were virtually identical to similar studies of the structure, carried out in other cohorts (10)(11)(12)22).…”

“…However, as a structure identified as a part of a number of inherited syndromes, such as the Beckwith-Wiedemann syndrome, Lachiewicz-Sibley and the brachio-oto-renal syndrome also known as Melnik-Fraser, there is very little modern evidence and information on the mechanisms of the individual transgenerational inheritance or lack thereof for PAuS (6,7,11,13,(20)(21)(22). Most of the research in the field, especially in the genetic and genealogical aspects, had been carried out prior to the 1950s and, to our knowledge, no similar studies have been carried out ever since (23)(24)(25)(26)(27)(28)(29).…”

Clinical perculiarities of preauricular sinus abscess: a tertiary health centre experience

“…2,3 Although can present as an infected and discharging sinus associated with abscess formation and can easily be misdiagnosed as a sebaceous cyst or a furunculus. [4][5][6] Preauricular sinus are prone to recurrent infection mainly by Staphylococcus aureus organism and usually presents with an intense irritation, pain, swelling/oedema, ear discharge, fever, headache and when the sinus punctum is blocked pus accumulates leading to abscess formation. Surgical intervention becomes an absolute option once the sinus gets infected and this will reduce recurrence, the incidence been reported to be 19-40%.…”

“…Surgical intervention becomes an absolute option once the sinus gets infected and this will reduce recurrence, the incidence been reported to be 19-40%. 4 Surgical drainage is necessary in the acute phase where abscess is present with institution of appropriate sensitive antibiotics. 2,[5][6][7] There is dearth of medical literature on preauricular sinus abscess in our region as obtained in other parts of the world.…”
