Patient and public involvement
This was a retrospective study, which enrolled 50 children with CRSwNP
who consecutively underwent functional endoscopic sinus surgery
in
A hospital, and B hospital from January 2018 to June 2020. The study
approved by the local Ethics Committee ([2016]096) without patient
consent for publication.We followed the RECORD-PE guidelines for
collecting the data. The Children who had consistent symptoms
(> 3 months), such as purulent nasal discharges, coughs,
headaches, and stuffy noses, even after maximum conservative treatment,
including medication and nasal irrigation, were diagnosed with chronic
sinusitis with nasal polyps based on a European position paper on
chronic rhinosinusitis 2020. All patients received 3-4 courses
antibiotic therapy, and nasal steroids spray prior to
function endoscopic sinus surgery (FESS).
All CT scans were performed using the Philips Brilliance IDT 64 slice or
iCT 256 slice scanner (Brilliance 64, Philips Healthcare, Cleveland, OH,
USA) and stored using a picture archiving and communication system
(Carestream PACS, Carestream Health, Inc. Rochester, NY, USA). Sinus CTs
were reviewed by an investigator masked to the patients’ clinical
condition. The presence of sinusitis (right and left frontal, ethmoid,
maxillary, and sphenoid) and anatomic variations: deviated nasal septum,
concha bullosa, Kuhn (frontoethmoidal), Haller (infraorbital), and
Onodi (sphenoethmoidal) cells were evaluated according to the European
Position Paper on the Anatomical Terminology of the nasal cavity by two
senior otolaryngologists.
The Chi-square test and Pearson correlation coefficient were used for
the statistical analysis. A P- value < 0.05 was accepted
as statistically significant.
