Bacterial Species Analysis and Proper Antibiotic Choices of Preauricular Fistular Abscess / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Infection of congenital preauricular fistula leads to preauricular abscess. Generally, the treatment for preauricular abscess is focused on subsiding abscess. Although incision & drainage is major point of therapy, the study of bacterial species and antibiotics for preauricular abscess is scant in literature. So, we investigated the most common species that cause preauricular abscess and the choice of proper antibiotics by using the databse available from the last 10 years. SUBJECTS AND METHOD: Our studies, from January, 2000 to December, 2010, included 86 patients in total (all in patients & out patients). We performed a retrospective review of bacterial species and culture analysis of each preauricular abscess. RESULTS: In this study, it was shown that most common pathogens causing preauricular fistula infection were Staphylococcus (27.9%), Enterococcus (9.3%), streptococcus and Klebsiella (5.8%) and Peptostreptococcus (4.6%). And Amoxicillin/cavulanate, Ciprofloxacin, Clindamycin had excellent effects of minimal inhibitory concentration through multiple pathogens. CONCLUSION: The choice of antibiotics for preauricular abscess will be targeted on Staphylococcus, Enterococcus, Streptococcus and anaerobic infection. Amoxicillin/clavulanate or Ciprofloxacin are the most effective antibiotics.

A Case of Schwannoma of the Nasal Tip: Resection Using an External Rhinoplasty Approach / 대한이비인후과학회지

Schwannoma is a benign tumor originating from the peripheral nerve sheath. A 16-year-old man have experienced progressive swelling of the nasal tip over 4 years. Computed tomography scan showed a 2.5 cm sized soft tissue density at the nasal tip. It distorted and dislocated the lower lateral cartilage. The mass was resected using an external rhinoplasty approach. The nasal tip was reconstructed by tip surgery and the soft tissue defect under the skin due to mass was filled with autologous dermal graft. The pathologic diagnosis was a schwannoma. A nasal tip schwannoma is extremely rare. Here, we present and discuss the clinical and surgical aspects of schwannoma arising on the nasal tip.
