Recurrence of sinonasal inverted papilloma following surgical approach: A meta-analysis

Objectives/Hypothesis

Inverted papilloma (IP) is a rare benign tumor, which is found in the sinonasal area. It is characterized by recurrence, local destruction, and malignant change. Of these, recurrence is a challenging problem to many otolaryngologists. In this study, we evaluated recurrence based on the type of surgical approach using a meta-analysis.

Study Design

MEDLINE, Embase, and Cochrane database.

Methods

Relevant studies were identified by searching the following databases: MEDLINE, Embase, and Cochrane through February 2016. Random-effects models were used to estimate risk ratio (RR) and 95% confidence interval (CI). The Newcastle-Ottawa scale was used to assess the quality of cohort studies.

Results

Our search yielded 14 retrospective cohort studies involving a total of 696 endoscopic approaches and 444 nonendoscopic approaches. The pooled RR for IP recurrence (endoscopic vs. external approach) was 0.56 [95% CI: 0.36-0.85, I²=48.3%]. A subgroup analysis was also performed.

Conclusions

Surgical management of IP via an endoscopic approach reduces the risk of recurrence compared to an external approach. Although further data are needed, early- stage IP requires endoscopic or endoscopic-assisted surgery to reduce the risk of tumor recurrence.
