摘要

Introduction

Oroantral communication (OAC) represents an abnormal connection between the oral cavity and the maxillary sinus, often arising after posterior maxillary extractions. Unmanaged OACs can lead to chronic sinusitis and fistula formation. Despite various treatment options, standardized guidelines are lacking. This study examined current management strategies, influencing factors, and practitioner confidence in treating OACs among dental professionals in the United States (U.S.).

Methods

A nationwide, cross-sectional online survey was conducted among 193 dental practitioners. The survey assessed demographics, management preferences by perforation size, timing of repair, material selection factors, and self-reported comfort levels. Associations between practitioner characteristics and management choices were analyzed using Cramer’s V. Multivariate logistic regressions were also performed to evaluate independent predictors of (1) management choice, and (2) timing of repair.

Results

Most respondents were male (72.8%) and mid-career practitioners. Management approaches varied by perforation size: collagen-based materials were common for small defects (0–2 mm), while specialist referral and flap techniques predominated for larger perforations (> 7 mm). 81% performed closure on the same day. Ease of use was the main factor guiding material choice (33.7%). Specialization showed a strong association with management approach (Cramer’s V = 0.654, p < 0.001), and experience with OAC cases was moderately to strongly related (Cramer’s V = 0.403, p = 0.007). In multivariate analyses, experience managing sinus perforations and self-rated confidence were associated with management choice, while no practitioner characteristics were independently associated with timing of repair.

Conclusion

Respondents demonstrated size-dependent escalation in OAC management, but variability persisted in technique and material selection. Adjusted analyses suggest that experience-related factors are more closely linked to material selection for moderate defects, whereas timing of repair appears relatively consistent across practitioner characteristics. These findings highlight the need for standardized, outcomes-informed guidance and targeted training to improve consistency and optimize patient outcomes.
