15 Nose and Nasal Skin Changes Associated With Rosacea and Autoimmune Conditions

9. Nasal Vestibulitis and Crusting

Nasal vestibulitis and crusting represent common but often overlooked manifestations of both rosacea and autoimmune conditions, causing significant discomfort and potential complications if left untreated. This condition involves inflammation of the nasal vestibule—the area just inside the nostrils—leading to pain, crusting, bleeding, and sometimes secondary bacterial infection. In rosacea patients, nasal vestibulitis may result from the chronic inflammatory state affecting the entire nasal region, while in autoimmune conditions like granulomatosis with polyangiitis, it may represent early mucosal involvement that precedes more serious complications. The pathophysiology involves disruption of the normal mucosal barrier, leading to increased susceptibility to bacterial colonization, particularly with Staphylococcus aureus. Chronic crusting can create a cycle of trauma and re-inflammation as patients pick at or remove crusts, leading to further tissue damage and delayed healing. The presence of persistent nasal crusting, particularly when associated with epistaxis or anosmia, should prompt evaluation for underlying systemic conditions. Treatment typically involves gentle nasal hygiene with saline irrigation, topical antibiotics when bacterial infection is suspected, and addressing the underlying inflammatory condition. In severe cases, systemic antibiotics may be necessary to treat secondary bacterial infection. Patient education about proper nasal hygiene and the importance of avoiding trauma to the nasal vestibule is crucial for preventing recurrence and complications.
