Endoscopic-assisted intraoral approach for mandibular condyle fracture management: A systematic review and meta-analysis.

OBJECTIVE

Surgical innovation led to an endoscopic-assisted intraoral approach for managing condyle fractures. The purpose of this systematic review is to purview the role of the endoscope and determine the range of information, summarizing the evidence for the benefit of surgeons on an endoscopic-assisted intraoral approach.

STUDY DESIGN

A literature search was conducted in PubMed, Google Scholar, Semantic Scholar, and Cochrane Library databases for studies mentioning the endoscopic intraoral approach for managing mandibular condylar fractures. Outcomes include the role of the endoscope, challenges, adjunct armamentarium, duration, and complications associated with the transoral and transbuccal approach for screw fixation. The meta-analysis was conducted with prevalence estimates and standardized means using STATA.

RESULTS

Thirty-nine studies were included. A 30° angulated, 4-mm-thick endoscope was the most commonly used endoscope. Two mini plates were most commonly used for fixation. Facial nerve weakness was higher in the transbuccal approach (1.24%) than in the transoral approach (0.8%). Pooled analysis (6 studies) showed that the duration of the surgical procedure was less in the transoral approach compared with the transbuccal approach for screw fixation. The bailout was 1.49%.

CONCLUSIONS

The endoscopic-assisted intraoral approach is reliable for condylar fracture management. The transoral and transbuccal approaches can be used for screw fixation with comparable outcomes.
