Purpose of review: Nasal septum perforation (NSP) is a communication between the two nasal cavities. This review contributes to the better knowledge of NSP causes, diagnosis, and treatment.
Recent findings: NSP prevalence is about 1%. Clinical presentation may range from absence of symptoms to the presence of bothersome sinonasal symptoms. NSP is more frequently caused by trauma or post-surgery, inflammatory diseases, and abuse substances. Conservative management (nasal irrigation, topical use of antibiotic or lubricant ointments, or placement of prosthesis) is considered the first-line treatment. Symptomatic NSP not improving with local therapies usually requires surgical approach. Selection of the technique for the endoscopic septal repair depends on perforation characteristics and surgeon experience. When NSP is diagnosed, its cause has to be promptly determined. Most of them can be controlled with conservative measures. Surgical/endoscopic approaches are usually needed in refractory cases, and new repair techniques have to be considered.
