Mucosal and Nasal Involvement and Their Correlation With Smell and Taste Functions in Lichen Planus Patients

The study aims to evaluate the impact of lichen planus on olfactory and gustatory functions in adults aged 18-65. Participants with lichen planus underwent taste and smell testing, oral and nasal mucosal examinations, and nasal endoscopy to detect potential mucosal involvement. A matched healthy control group also completed taste and smell tests to provide comparative data. This design allows the assessment of whether mucosal involvement in lichen planus correlates with changes in taste and smell, which may contribute to better clinical understanding and management of the disease.
