Abstract Objective Primary ciliary dyskinesia (PCD) is characterized by upper and lower airway disease. Multiple studies have demonstrated the progression of pulmonary disease; however, longitudinal changes in the otologic and nasal symptoms have not been well described in patients. This study defines age‐related prevalence, age of onset, and age‐related trends in self‐reported otologic and sinonasal comorbidities in individuals with PCD. Study Design A prospective, longitudinal, multicenter, observational study spanning up to 12 years. Setting Six PCD centers in North America. Methods Inclusion criteria were 1 sinus surgery. Conclusion There is a high prevalence of reported otologic and sinonasal morbidity among people with PCD that begins during early childhood and persists. Further analysis is indicated to evaluate differences over time among participants with varying ultrastructural defects. Level of Evidence Level 2.
