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 a er 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 postopera-tively. 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. C 2020 ARS-AAOA, LLC.

Objectives Although lateral osteotomy is an important part of rhinoplasty, it is known to be closely associated with postoperative eyelid edema and ecchymosis after rhinoplasty. There is no consensus on which osteotomy methods are effective in reducing morbidity from rhinoplasty. This study compared the effects of different osteotomy methods on edema and ecchymosis after lateral osteotomy using a meta‐analysis. Study Design A literature search using MEDLINE, SCOPUS, and Cochrane databases. Methods Two authors independently reviewed the databases published until May 2019. Randomized controlled trials that compared lateral osteotomy methods (external approach) with different methods (internal approach), for which the outcomes of interest were mucosal injury, edema, and ecchymosis on postoperative days, were included. Sufficient data for meta‐analysis was found in six studies with a total of 224 patients. Results In a comparison of the external approach with the internal approach, mucosal injury was significantly lower in the external approach (odds ratio = 0.41; 95% confidence interval = [0.11; 0.99], I2 = 29%). There were significant differences between the external and internal approach in eyelid ecchymosis and edema, except for eyelid ecchymosis at 7 days postoperatively. However, all significant results showed a small effect size with a standardized mean difference near 0.2. Conclusions The external approach during lateral osteotomy had no significant advantage in edema and ecchymosis compared to the internal approach. Further studies with good research methodology should be carried out to determine the effect on the postoperative complications of different lateral osteotomy methods. Laryngoscope, 131:54–58, 2021

Objectives. Although osteotomy is an important part of rhinoplasty, it is known to be closely related to postoperative eyelid edema and ecchymosis. We aimed to evaluate the effects of periosteal elevation prior to osteotomy on eyelid edema and ecchymosis.Methods. Two authors reviewed studies in the Medline, Scopus, and Cochrane databases published through May 2019. Randomized controlled trials comparing periosteal elevation (subperiosteal tunneling) with periosteal preservation that reported eyelid edema or ecchymosis or subconjunctival hemorrhage as outcomes of interest were included. From each study, the baseline characteristics of the study subjects, the quality of the study, the number of patients in the treatment and control groups, and outcomes were extracted.Results. Data for meta-analysis were identified in six studies with a total of 208 patients. Eyelid ecchymosis and edema within 3 days postoperatively were significantly more common in the periosteal elevation group than in the preservation group, although such an association was not found for edema on postoperative day 7 (standardized mean difference [SMD], 0.21; 95% confidence interval [CI], –0.09 to 0.50; I² =0%). There was no significant difference in subconjunctival hemorrhage on day 1 (SMD, 0.31; 95% CI, –0.09 to 0.72; I² =0%).Conclusion. Periosteal preservation during lateral osteotomy may reduce eyelid edema and ecchymosis compared to periosteal elevation. Further studies with rigorous research methods should be carried out to determine the effectiveness of different techniques in lateral osteotomy.
