Abstract
BACKGROUND: Fibrin sealants (FS) are commercially available products used in surgical wounds as adjuncts to haemostasis and closure of dead space. The role of FS in soft tissue head and neck surgery has not been established. OBJECTIVES: To assess whether FS improves wound-related outcomes in patients undergoing soft tissue surgery of the head and neck anatomical region that would commonly require a drain. TYPE OF REVIEW: Systematic review and meta-analysis of randomised controlled trials (RCTs). SEARCH STRATEGY: MEDLINE (1946-2016), EMBASE (1974-2016), PubMed (2016), CENTRAL (2016), ClinicalTrials.gov (2016), WHO International Clinical Trials Registry and Platform (2016), Research Gate (2016). EVALUATION METHOD: Two independent reviewers screened and selected studies. Included studies were assessed for risk of bias and data extracted using a predetermined data collection form. RESULTS: Of the 421 studies that were screened, 11 RCTs met the inclusion criteria. There were two RCTs on thyroidectomy, three on "surgery involving neck dissection" (central or lateral), five on rhytidectomy and one on parotidectomy. There was a tendency for FS to reduce "mean total drainage volume" (mean difference -26.86 mL, 95% CI -43.41 to -10.31, I2 =97%, P=.001). Subgroup analysis of thyroidectomy (mean difference -36.36 mL, 95% CI -72.82 to 0.10, I2 =79%, P=.05), "surgery involving neck dissection" (mean difference -33.21 mL, 95% CI -70.01 to 3.59, I2 =94%, P=.08) and rhytidectomy (mean difference -13.79 mL, 95% CI -17.57 to -10.01, I2 =0%, P < .00001) concurred with the overall analysis. There was a suggestion that FS may reduce "mean retention time of drains" by 1.24 days (95% CI -3.32 to 0.85, I2 =99%, P=.25) and "hospital length of stay" by 2.09 days (95% CI -5.18 to 0.99, I2 =97%, P=.18), but this was not statistically significant. There was also a suggestion that FS may protect against adverse events (RR 0.69, 95% CI 0.35 to 1.38, I2 =0%, P=.29) and haematoma/seroma formation (RR 0.49, 95% CI 0.22 to 1.07, I2 =0%, P=0.07). CONCLUSIONS: There was considerable heterogeneity within the RCTs included in this study, thus restricting definitive conclusions. FS has however shown a definite benefit in rhytidectomy and potential benefit in other soft tissue head and neck surgical procedures. Further pragmatic trials are required particularly in the field of lateral neck dissection.
