Nasal vestibular furunculosis: Summarised case series.

Objective: Nasal vestibular furunculosis (NVF) is characterized by an acute localized infection of the hair follicle in the skin lining of the nasal vestibule. This study provides an up-to-date narrative analysis on NVF, its presentation, complications and management.

Methods: A literature search was conducted electronically with no time constraints using "Nasal Vestibular Furuncolosis" or "NVF" through Medline, Cochrane Library and Web of Science, including MeSH terms with no language restrictions. Included were: Studies that described NVF's presentation and subsequent management and excluded were: Irrelevant studies that did not provide details about NVF's presentation or management, furthermore studies that alluded to Nasal vestibulitis without furunculosis were excluded. There were no limitations on time, up until the review was commenced in May 2020.

Results: Seven articles complied with the inclusion criteria. All papers reviewed were from 2015 to 2020. Three out of 4 studies reported duration of symptomatic NVF between 3 and 4 days. The most common presentation of NVF was reported as erythema, swelling, tender over the nasal tip. The most frequent, successful management of NVF frequently included intranasal topical mupirocin and in some cases oral sodium fusidate. NVF was reported to clear within 7 days by 2 studies. There were no randomised studies exploring NVF or NVF management.

Conclusion: Although a very common condition, much research is required to allude to the pathophysiology and management of NVF. Future studies should explore the reasons as to the resistance of topical antibiotics in some patients, the differing strains of staphylococcus aureus and their resulting complications, the reasons behind the familiar connection and the most effective management plan for NVF.
