ABSTRACT
Cystic fibrosis (CF) is an autosomal recessive disorder affecting exocrine gland function. Although CF was formerly a deadly disease of infants and children, recent improvements in antibiotics, nutritional therapy, and supportive care have extended the median survival to adulthood. Patients with CF often present with sinusitis and nasal polyposis in addition to recurrent pulmonary infections. Although the effectiveness of endoscopic sinus surgery in children with CF has been documented, the treatment guidelines and efficacy in the adult CF patient are unknown. We present a series of 16 adult patients with CF and chronic sinusitis. The majority of patients presented with nasal polyposis and concomitant pulmonary complications. Endoscopic findings are reviewed, with an emphasis on improving pulmonary function following endoscopic sinus surgery. Preliminary findings suggest that endoscopic sinus surgery improves symptoms of sinusitis and exercise tolerance and may delay the progressive respiratory failure that often affects the adult CF patient.
