Cystic fibrosis and endoscopic sinus surgery: Relationship between nasal polyposis and likelihood of revision endoscopic sinus surgery in patients with cystic fibrosis.
OBJECTIVE
To observe the extent of nasal polyposis endoscopically in a cystic fibrosis population before the first surgical intervention and to grade the extent using a modified Malm scale, to observe patients prospectively and record the need for revision endoscopic sinus surgery (ESS), and to compare this among the individual polyp grading groupings.


METHODS
Retrospective medical record review of data collected prospectively.


METHODS
Tertiary care hospital.


METHODS
Forty-nine consecutive patients with a clinical preoperative diagnosis of cystic fibrosis and sinusitis.


METHODS
Using a modified Malm scale, the extent of polyps was prospectively graded into 3 groups before the first surgical intervention. The number of patients needing revision ESS and the mean time to revision ESS were compared among the 3 groups.


RESULTS
Forty-nine consecutive patients underwent ESS between 1992 and 2007. We used a 3-stage system for extent of polyposis: 16 patients were noted to have no polyps (grade A), 14 had mild polyposis (grade B), and 19 had extensive polyposis (grade C). During the study, 14 patients required revision surgery: 3 with mild polyps and 11 with extensive polyps. Mean time to revision surgery was 39.7 months for those with grade B and 23.8 months for those with grade C. In the overall statistical analysis, the rate of revision ESS was significantly different among the 3 groups (P < .001). In pairwise comparisons, there were significant differences between those with grades A and C (P < .001) and between those with grades B and C (P = .04) and a trend toward significance between those with grades A and B (P = .052). There were no complications from ESS.


CONCLUSIONS
Preoperative grading of nasal polyposis in patients with cystic fibrosis can help assess the future likelihood of revision ESS.
