Abstract

Introduction: The lesions of pinna are not uncommon. Pinna, a delicate, vulnerable structure is more liable for trauma. The present study aimed to examine the various types of benign lesions of pinna and management with appropriate intervention.
Materials and Methods: This prospective study was conducted for a period of 2 years in Department of ENT of our medical college Hospital, Bengaluru, Karnataka, India. A total of 140 subjects were examined in this study from ENT out patient department. The patients with various benign lesions of pinna were included in this study. A detailed clinical history regarding onset, predisposing factors and associated conditions were collected. Routine blood and urine examination were done. Depending on the type of lesion patients were managed conservatively or surgically.
Results: A total of 140 subjects were examined in this study. Majority of the patients were in the age group of 21-30 years. i.e. 61(44%) patients, followed by 29(21%) were in the 31-40 years. Most of the patients presented with Keloid, 56(39%), 42 (32%) cases were Pseudocyst of auricle, 37(26%) were Perichondritis, Herpes Zoster Oticus and sebaceous cyst were observed in 2 cases each, followed by a case of Neurofibroma. Keloid was more predominant in females than males. Pseudocyst of auricle and
Perichondritis were little more in males than female subjects. Keloid was unilateral in 43(77%) patients and bilateral in 13(23%) cases. Trauma is the predisposing factor in most of the cases, followed by ear piercing/iatrogenic. Keloid patients were managed with complete excision of the lesion followed by intralesional triamcinolone. Pseudocyst auricle was observed in 42 patients, its prevalence was more in males. Trauma is the main pre-disposing factor. Pseudocyst auricle was managed by aspiration, and by
window procedure. Perichondritis was observed in 37 cases, again trauma was the main predisposing factor observed in 54% cases followed by ear piercing/iatrogenic in 27% cases. In addition, 78% cases were managed by incision and drainage and 22% cases were managed conservatively with broad spectrum antibiotics.
Recurrence in 5% cases of keloid, 29% cases of pseudocyst of auricle was observed after complete excision and aspiration respectively.
Conclusion: Our study results conclude that various benign lesions of pinna such as keloid, pseudocyst of auricle, perichondritis, Herpes Zoster Oticus, sebaceous cyst, and neurofibroma of pinna can be managed conservatively or surgically. Trauma is the most important predisposing factor in majority of the lesions. Diabetes Mellitus plays a pivotal role in the prognosis of perichondritis and Herpes Zoster Oticus.
