SA3 - Impact of a Combined ENT–Oral Surgery Clinic on Diagnostic Accuracy and Management

Abstract: Background: Care for patients with complex oral and maxillofacial surgery-ENT conditions is often fragmented between otolaryngology and oral and maxillofacial surgery, potentially leading to delays in diagnosis, duplication of investigations, and suboptimal treatment planning. Multidisciplinary clinic models may improve efficiency and clinical decision-making, but data on their impact in oral surgery populations remain limited.

Method: A retrospective review was performed of patients seen in a combined ENT-OMS multidisciplinary clinic at a tertiary referral center. A total of 45 consecutive patients were included. Data collected included referral source, presenting complaint, provisional diagnosis, investigations, and management plans before and after multidisciplinary review. Primary outcomes were change in diagnosis and change in management. Secondary outcomes included need for combined surgical care, time to definitive management, and avoidance of duplicate investigations.

Results: A total of 45 patient records were assessed retrospectively given the above data parameters. Management plans were altered in [76%] of cases, including transition from single discipline management to a combined surgical approach. Combined ENT-OS operative management was required in 58% of patients. The multidisciplinary model reduced duplication of imaging/investigations in cases and shortened time to definitive management by 18 months. Common indications included odontogenic infections with sinonasal involvement and maxillary sinus pathology of dental origin such as cystic displacement of teeth.

Conclusion: A combined ENT-OSA clinic significantly impacts diagnostic accuracy and management in complex oral and maxillofacial surgery patients. This model enhances care coordination, reduces unnecessary investigations, and facilitates timely, definitive treatment. These findings support the adoption of multidisciplinary clinic pathways to optimize outcomes and efficiency in oral and maxillofacial surgical practice.
