Evaluating Artificial Intelligence’s Role in Developing Research Questions in Head and Neck Reconstruction

Generative artificial intelligence (AI) large language models are an emerging technology, with ChatGPT and Gemini being 2 well-known examples. The current literature discusses clinical applications and limitations of AI, but its role in research has not yet been extensively evaluated. This study aimed to assess the role of ChatGPT and Gemini in developing novel and clinically relevant research ideas (RIs) for systematic reviews (SRs) in head and neck reconstruction. ChatGPT and Gemini were prompted to provide 10 novel and clinically relevant RIs for SRs in the following domains: head and neck reconstruction in general, microsurgery, and complications in reconstructive head and neck procedures. A comprehensive search was then performed for SRs in MEDLINE, Cochrane Library, and Embase to determine the novelty of the RIs generated. A total of 60 RIs were generated, with half created by ChatGPT and the other half by Gemini. Overall, 3613 entries were found through the literature search. After deduplication and screening, a total of 50 studies that partially addressed the AI-generated RIs were identified and were included in the present review. Out of the 60 AI-generated RIs, 42 had not been previously studied and were therefore considered novel. No statistically significant differences were found between the outputs generated by Gemini and ChatGPT. Both ChatGPT and Gemini were able to effectively generate novel and clinically relevant RIs for SRs, although their suggestions were generally broad. This study demonstrated that AI could potentially aid in the process of conducting novel SRs.
