Objective: Nasal septal abscess is an uncommon condition but it can cause potentially life-threatening intracranial complications and cosmetic nasal deformity. Methods: We analyzed ten years of cases to determine the optimal diagnostic and therapeutic modalities. A retrospective review of case notes from Tri-Service General Hospital archives was performed. Records of six patients diagnosed with nasal septal abscess, who were treated from September 2007 to August 2017 were retrospectively reviewed. Patients’ clinical symptoms, etiology, diagnostic methods, bacteriology, antibiotic and surgical treatment were recorded and analyzed. Results: Out of six patients diagnosed with nasal septal abscess, three were male and three were female. Ages ranged from 19 to 75 years (mean 51 years). The most common symptoms at presentation were nasal pain and nasal obstruction. Typical etiologies were trauma or acute sinusitis, but uncontrolled diabetes mellitus was also an important etiology. In the series of six patients, four of them had positive findings of abscess and in drainage, had the following bacterial cultures: Staphylococcus aureus (two cases), methicillin-resistant S. aureus (one case), and Klebsiella pneumoniae (one case). In addition to antibiotic treatment, all patients underwent surgical drainage and had complete resolution of disease without intracranial complications during at least 1 year of follow-up. However, two out of the six patients developed saddle nose deformity. Conclusions: This study highlights that: 1. In view of the rapidly increasing number of diabetes mellitus cases, uncontrolled diabetes mellitus is an important etiology of nasal septal abscess. 2. Although S. aureus is the most common pathogen, we must pay attention to methicillin-resistant S. aureus (MRSA) to prevent severe complications and patients who are at increased risk for MRSA colonization should be administrated antibiotics against MRSA initially. 3. Nasal septal abscess should be managed with parenteral broad spectrum antibiotics, appropriate drainage and immediate reconstruction of the destructed septal cartilage with autologous cartilage graft, to prevent serious intracranial complications and cosmetic nasal deformity.
