Differential characteristics of pediatric sinusitis in patients who underwent endoscopic sinus surgery: children vs. adolescents.

OBJECTIVES: We hypothesised that paediatric chronic sinusitis patients might have various clinical characteristics, depending on age, compared symptoms, physical findings and clinical features in younger children and older adolescent patients who underwent endoscopic sinus surgery. DESIGN: A retrospective review of medical records. SETTING: A total of 195 paediatric patients who underwent Endoscopic sinus surgery were enrolled and medical records were reviewed. PARTICIPANTS: The subjects were divided into children (age < 12 years, n = 70, mean age = 9.6 years) and adolescents (age ≥ 12 years, n = 125, mean age = 14.7 years). MAIN OUTCOME MEASURES: Subjective symptoms, physical findings, CT images and clinical features were compared in children and adolescent groups. RESULTS: Cough and nasal obstruction were more common in adolescents, and sleep disturbance was more common in children. Nasal mucosal injection was more common in adolescents, whereas tonsils were larger in children. Septal deviation was a more common finding in adolescents, and total CT score and serum total IgE levels were higher in children. There was no statistical difference in rate of recurrence after endoscopic sinus surgery. CONCLUSION: The clinical features of paediatric chronic sinusitis differed between the younger and older groups. Symptomatic, anatomical and clinical differences between these two groups suggest that further study of paediatric chronic sinusitis should stratify patients by age to better understand the effects of treatment on each age group.

Comparison of calcium alginate and carboxymethyl cellulose for nasal packing after endoscopic sinus surgery: a prospective, randomised, controlled single-blinded trial.

OBJECTIVES: Calcium alginate is a biodegradable gel-transforming agent widely used for nasal packing. It can reduce pain and improve comfort. However, few randomised controlled trials have compared the efficacy of calcium alginate nasal packing with that of other biodegradable gel-transforming materials. DESIGN: Prospective, randomised, single-blinded controlled study. SETTING: Yonsei University Severance Hospital, a tertiary academic medical centre. PARTICIPANTS: Twenty-seven patients (54 nostrils) with chronic rhinosinusitis who were scheduled for bilateral endoscopic sinus surgery were enrolled. After surgery, one nostril was packed with calcium alginate and the other with carboxymethyl cellulose. Only patients with an intersinus chronic rhinosinusitis severity score difference of ≤1 were included. MAIN OUTCOME MEASURES: Visual analogue scale (VAS) scores for postoperative pain, discomfort from nasal discharge and pain during packing removal were analysed. Two independent rhinologists who were blinded to the assessments separately scored adhesions, oedema and infection by endoscopic digital photography at 1, 4 and 8 weeks postoperatively. RESULTS: There were no significant differences in VAS scores for postoperative pain, discomfort from nasal discharge or pain during packing removal between calcium alginate packings and carboxymethyl cellulose packings. Inter-rater variability of adhesion, oedema and infection scores was acceptable. Adhesion severity and oedema scores at 4 weeks were significantly lower with calcium alginate packing than with carboxymethyl cellulose. Infection severity scores also tended to be lower with calcium alginate than with carboxymethyl cellulose, but the difference was not significant. CONCLUSIONS: Calcium alginate nasal packing is associated with reduced severity of oedema and adhesions after endoscopic sinus surgery.
