Other syndromes that have been associated with a preauricular sinus include:
- branchio-oto-ureteral syndrome
- branchi-otic syndrome
- brancho-otic-costal syndrome
- Tetralogy of Fallot and clinodactyly (curving of the finger)
- steatocystoma multiplex
- the deafness, preauricular sinus, external ear anomaly and commissural lip pit syndrome
- cat eye syndrome
However, most of these associations have been reported in only a few cases (and sometimes within a single family).
Experts have recommended that if a preauricular sinus is diagnosed, auditory testing and a renal ultrasound may be appropriate in some cases. When no associated abnormalities or birth defects are present and the sinus does not cause symptoms or problems, there is general consensus that no further action is necessary.
