Background Nasal obstruction is a common cause of breathing problems with lateral wall insufficiency (LWI) a key anatomic contributor. Recently, a bioabsorbable nasal implant was introduced to correct LWI and treat nasal obstruction. The goal of this study was to perform a systematic review with meta‐analysis to determine the efficacy of the bioabsorbable nasal implant for treating nasal obstruction caused by LWI. Methods Five databases (PubMed, SCOPUS, EMBASE, Web of Science, and the Cochrane Database) were independently reviewed by 2 researchers, starting at the earliest time point recorded in the database to September 2019. Studies that scored endoscopic lateral wall movement and nasal obstruction related to quality of life (QOL) postoperatively before and after bioabsorbable nasal implants and those that compared the outcomes of nasal implants (treatment group) with outcomes of sham surgery (control group) were included in the analysis. Results Five studies (396 patients) met the inclusion criteria. Bioabsorbable nasal implants significantly reduced endoscopic lateral wall motion compared to pretreatment values and also improved QOL at 12 months postoperatively. Most adverse effects following the nasal implant, such as skin or mucosal reaction, infection, or implant retrieval, were reported with a 5% incidence rate. All adverse outcomes were resolved without significant sequelae. Compared with sham surgery, bioabsorbable nasal implants significantly improved disease‐specific QOL. Conclusion Bioabsorbable nasal implants may reduce nasal wall movement and subjective symptom scores compared to preoperative status. More randomized clinical trials must be conducted to further verify the effectiveness of bioabsorbable nasal implants.
