Complications of primary pediatric endoscopic sinus surgery for chronic rhinosinusitis: A 25-year single surgeon experience.

Objective: To report our experience on the complications of primary pediatric endoscopic sinus surgery (ESS).

Methods: Case series of pediatric ESS performed from 1991 to 2016 on children who failed maximal medical therapy and/or adenoidectomy. Inclusion criteria were children (age <12 years old) who underwent primary ESS with or without adenoidectomy for chronic rhinosinusitis (CRS) after failed maximal medical therapy and/or adenoidectomy. All patients underwent maxillary antrostomy ± partial or total ethmoidectomy. Patients with complicated acute rhinosinusitis were excluded. Complications reviewed included: skull base injury and CSF leak, orbital injuries (blindness, orbital hemorrhage, emphysema, periorbital swelling and bruising, fat exposure), and bleeding requiring intervention.

Results: A total of 352 patients underwent ESS between 1991 and 2016. There were no blindness or orbital hematoma reported, and no major nasal bleeding requiring intervention. The total number of complications was 31 (8.8%): 1 (0.3%) CSF leak, 3 (0.85%) orbital emphysema, 5 (1.4%) periorbital ecchymosis, and 22 (6.3%) lamina papyracea violation with orbital fat exposure.

Conclusions: Complications of primary pediatric ESS can be rare dependent on surgeon's experience, the most common being orbital injury.Level of evidence: 4.
