Objective: Arteriovenous malformations (AVM) of the ear show unique features. Progressive growth or inadequate management of AVMs may lead to bleeding, infection, cartilage exposure, and ultimately loss of structure. Total ear amputation is an alternative; however, due to the structural complexity of the ear, reconstruction is technically challenging. This study presents a treatment algorithm based on a clinical series, with treatment options including resection and immediate and late reconstruction.Methods: Between 2004 and 2018, 12 patients with auricular AVMs were treated with AVM resection and ear reconstruction at our hospital. Among these 12 patients, seven were women, and patients' ages ranged between 4 and 34 years. Parameters considered before resection and reconstruction were compromised ear extension (partial, total, or extra-auricular involvement), thickness (cutaneous and cartilaginous), symptoms (bleeding, infection, ulceration, and/or cartilage exposure), and preoperative embolization. Total resection of AVMs was planned as the first step in all cases, followed by primary closure. AVM resection was categorized into a partial or total procedure, resulting in partial or total ear defects. Reconstruction was categorized as immediate or delayed.Results: Preoperative embolization was performed in 10 patients. AVMs were totally removed, resulting in seven total ear amputations. In six of these patients, total ear reconstruction was performed 6 months later, and all patients were recurrence-free. Only one patient did not undergo ear reconstruction. Regrowth was not observed in any reconstructed ear.Conclusion: Treatment of ear AVMs requires a planned approach to achieve favorable clinical outcomes and for concomitant safe and definitive reconstruction.

“…Although some of the complications (e.g skin necrosis) can be solved by subsequent resection, caution is still needed. Therefore, some authors believed that whether preoperative embolization needs to be performed depends on the condition of auricular AVMs, for example, it may not be used for localized lesions 5,73 . In addition to preoperative embolization, other methods also can be used to reduce intraoperative bleeding, including hypotension anesthesia, multiple sutures around the lesion, intraoperative ligation of the supply or reflux vessels, and application of epinephrine, coagulant drugs, arterial clips, or electrocautery devices 6,25,41,74,75 …”

Auricular arteriovenous malformations (AVMs) can cause a variety of symptoms that seriously impact the patient's appearance, life, and mental well-being. Surgery is the primary management method for auricular AVMs, but there is no consensus on how to surgically manage auricular AVMs. In this article, we document a comprehensive review of the characteristics, classification, and surgical interventions to treat auricular AVMs.

Introduction and Aim: Most of the lesions affecting pinna are cutaneous conditions. Those arising from the cartilage are extremely rare, whereas those from the soft tissue like vascular, stromal and adnexal components are relatively common. The present study aims at analysing the proportion, types, and categories of lesions affecting the pinna. Methods: Following institutional ethics committee approval, a retrospective analysis of medical records of 40 patients who underwent surgical excision of pinna lesions from 2006 to 2018 was conducted at a tertiary care hospital in Dakshina Kannada, India. Lesions were grouped as benign adnexal, benign soft tissue, malignant lesions, and infection/inflammation. Results: Median age was 47.5 years and mode was 59 years. There were thirty (75%) males and ten (25%) females. The commonest lesions included epidermal cyst (25%), followed by seborrhoeic keratosis (17.5%), and squamous cell carcinoma (10%). Conclusion: A wide spectrum of entities affecting the pinna were encountered in the present study. Superficial cystic lesions are the most frequent type found in pinna and are amenable to simple excision. Benign neoplasms require surgical intervention; malignancy is also to be kept in mind while making a clinical diagnosis, necessitating wide clearance with or without neck dissection. Early intervention and confirmation of diagnosis by histopathological examination helps not only in successful management but also in preventing disfigurement and psychosocial complications.
