Primary ciliary dyskinesia (PCD) is an inherited disease responsible for a disruption of normal ciliary function. Its clinical presentation is usually in early childhood with pulmonary and otorhinolaryngologic symptoms. Early diagnosis is essential to avoid the development of bronchiectasis. The aim of the study was to retrospectively review the clinical features of children suspected to have PCD. ⋯ This case series highlights the key clinical features of recurrent otitis, sinusitis, and situs inversus, especially when occurring in combination with bronchitic symptoms. Measures of nasal nitric oxide are useful for the diagnosis of PCD and in the case of high levels of NO, PCD is unlikely. Results may not be definitive and TEM analysis of biopsies is still indispensable to ensure the diagnosis and guide genetic counselling.
