Meta‐analysis comparing outcomes of different transoral surgical modalities in management of oropharyngeal carcinoma

Abstract

Background

Optimal transoral surgical modality for oropharyneal carcinoma is currently unclear. Transoral laser surgery (TLS), transoral robotic surgery (TORS), and conventional direct transoral (DT) oropharyngectomy are the main current transoral surgical modalities for oropharyngeal carcinoma.

Methods

MEDLINE was systematically searched through PubMed. Reference lists were reviewed. Random‐effects models were used to combine studies within each group. Tests for heterogeneity were used to explore difference in effect size between groups in subgroup analysis.

Results

Nine studies (404 patients) in TORS arm, five studies (498 patients) in TLS arm, and three studies (335 patients) in DT arm were included. Early T classification (T1‐T2) for TORS and DT were higher compared to TLS group (P < .001). There was no significant difference between groups in the rate of invaded margin, post‐operative oropharyngeal bleeding, temporary tracheotomy, and gastrostomy dependence.

Conclusion

The available data do not yet provide clear evidence of superiority of any one modality.
