Abstract
Introduction: A preauricular sinus, also known as a congenital auricular fistula, a congenital preauricular fistula, a geswein hole, an ear pit or a preauricular cyst, is a common congenital malformation characterized by a nodule, dent or dimple located anywhere adjacent to the external ear.
Objectives: 1) To describe the socio-demographic profile of patients with preauricular sinus.2) To categorise the patients of preauricular sinus on the basis of it’s laterality and presenting complaints.3) To categorise the patients of preauricular sinus on the basis of treatment modality and recurrence.
Materials and Methods: The present study was done on 32 patients of preauricular sinus who presented to the ENT Out Patient Department (OPD) in Rajendra Institute of Medical Sciences (RIMS), Ranchi from June 2015 to November 2016. Templates were generated in MS excel sheet and data analysis was done using SPSS software (version 20).
Design of Study: Record based study.
Results: Preauricular sinus were more common in younger age group (<20 years) 71.88%(n=23), females 53.12% (n=17) and literate 59.38% (n=19). Preauricular sinus were more common in patients from urban background 65.63% (n=21) and non tribal ethnicity 68.75%(n=22). Preauricular sinus were mostly unilateral 78.12% (n=25) and right sided 43.75%(n=14). Left sided preauricular sinus were seen in 34.37% (n=11) while 21.88% (n=7) of all the cases were bilateral. Recurrent discharge (81.25%) was the most common presenting complaint for patients with preauricular sinus, followed by pain (68.75%), swelling(65.63%) and itching(53.13%). Wide excision of the sinus tract had given best results for preauricular sinus, with a low recurrence rate (6.67%).
Conclusion: More than 2/3rdcases of preauricular sinus were in younger age groups and unilateral in more than 3/4thcases. Wide excision of sinus tract showed best results.
