Sinonasal and orbital pathologies present unique challenges due to their anatomical complexity requiring advanced surgical approaches for optimal management. This systematic study demonstrates the effectiveness of combined surgical interventions based on advancements in minimally invasive approaches. An electronic literature search was performed on articles reporting patient outcomes after combined surgical management in sinonasal and orbital pathologies through the PubMed, Scopus, and Cochrane databases. Under the inclusion criteria, randomized controlled trials, literature reviews, cohort studies, and case reports published in the last decade on reputable journals were taken under consideration. Complications and functional outcomes were improved as compared to the conventional surgery techniques when looked into the previous evidences. Heterogeneities of the study designs and duration of follow-up did not permit a meta-analysis. The endoscopic orbital decompression, and other such sinonasal surgeries were now performed with less intraoperative blood loss, shorter hospital stays, and quicker recovery times. After all research, it can be concluded that combined surgical techniques do improve outcomes, but more high-quality, standardized work needs to be done to establish long-term efficacy. Our research findings support this trend of minimalization of invasive techniques to treat pathologies within the sinonasal and orbital spaces and stress their overall capacity to enhance postoperative results. Future research should focus on standardizing protocols and longer follow up periods to evaluate recurrence and long-term complications better.
