Background:Pseudocyst of the auricle is a benign condition of the ear characterized by an asymptomatic, noninflammatory swelling on the lateral or anterior surface of the auricle. It typically presents as a 1 to 5 centimeter cystic lesion located within the scaphoid or triangular fossa. In most patients, the lesion develops spontaneously. However, pseudocyst of the auricle has also been associated with trauma to the ear.Purpose:We describe the clinical findings of two men who developed pseudocyst of the auricle associated with ataxia-induced trauma to their ear. We also summarize the differential diagnosis, the postulated pathogenesis, and the treatment options for this condition.Materials and methods:The features of two men with pseudocyst of the auricle are presented. Using PubMed, the following terms were searched and relevant citations assessed: ataxia, auricle, dyskinesia, ear, Friedreich’s, neurological, pinna, pseudocyst, spasticity, spinocerebellar, and trauma. In addition, the literature on pseudocyst of the auricle is reviewed.Results:Pseudocyst of the auricle was observed in two men with neurological disorders: a 33-year-old Asian man with spinocerebellar ataxia and a 47-year-old Caucasian man with Friedreich’s ataxia. Each patient had a history of ataxia-induced head and ear trauma. The clinical features of the lesions were sufficient to establish a diagnosis of pseudocyst of the auricle. Neither patient desired treatment.Conclusion:Pseudocyst of the auricle is a benign cystic lesion that is occasionally precipitated by trauma to the affected ear. Patients with neurological disorders, particularly those associated with ataxia and/or dyskinesias, may have an increased risk of developing the traumatic variant of the condition. Diagnosis can usually be established by clinical presentation. However, in some patients, a tissue specimen may be secured for microscopic evaluation to exclude infection or during surgical repair. Various treatment options exist for pseudocyst of the auricle, including: (1) needle aspiration—with or without subsequent injection of an irritant substance—followed by a pressure dressing and (2) surgical deroofing. Alternatively, reassurance of the benign nature of the condition and observation is a reasonable management alternative.

Auricular pseudocysts: a systematic review of the literature

Background Auricular pseudocysts are benign fluid accumulations of the ear of uncertain etiology. Little is known about the optimal modality to successfully treat these lesions. No systematic review addressing auricular pseudocysts have been published to date. Objectives The aim of this study is to summarize all the published data regarding diagnostic and therapeutic challenges of auricular pseudocysts. Methods On May 28, 2020, a systematic search of Medline, Embase, and Cochrane databases was conducted. All the studies describing treatment of auricular pseudocysts, procedure description, outcome, and follow‐up period were included in this review. Results After full‐text article review, 74 articles were included, representing a total of 1,011 lesions. The commonly used treatments for auricular pseudocysts were deroofing (493 lesions), aspiration (284 lesions), incision and drainage (171 lesions), intralesional steroids (53 lesions), and observation (10 lesions). The highest cure rate was found with the deroofing procedure (97.2%) followed by incision and drainage (95.9%). The mean follow‐up period was 6.7 months. Conclusion Surgical procedures (anterior deroofing or incision and drainage) showed the highest cure rates and should be considered as first‐line treatment for auricular pseudocysts. Future adequately designed randomized controlled trials are warranted to compare the efficacy of the techniques described.

Competitive advantage is the ability to grow faster than your competitors with the use of same amount of investment (Ming, Hong, Shuen, & Lim, 2004).

The aim of this paper is to propose the relationship of High Performance Work Systems (HP-WSs) with Faculty Productivity in higher education sector by using VRIO-LDN approach of Resource Based View (RBV). Researchers have used qualitative methodology where interpretivistic philosophy is applied to explore various models and comparative studies for framework development. Researchers have searched Emerald and Wiley-Blackwell databases using multiple keywords to identify relevant articles. The findings of this paper includes the Ability enhancing, motivation enhancing and opportunity enhancing HPWSs that impact the faculty productivity through the moderator i.e. VRIO-LDN approach of RBV. The current research has addressed the neglected area of higher education sector i.e. Faculty Productivity Enhancement by considering them valuable, rare, inimitable, organizational focus, low-tradable, durable and non-substitutable asset of the organization through the implementation of Resource Based view.
