With increasingly limited operative resources and patient desires for minimally invasive procedures, there is a trend toward local endoscopic procedures being performed in the outpatient clinic setting. This study aims to assess the efficacy of a novel lateral nasal wall block for use in office-based endoscopic sinus surgery.

A prospective cohort study assessing consecutive patients undergoing office-based endoscopic sinus surgery using our described lateral nasal wall block anesthesia technique. Procedural patient comfort was assessed using the ISAS, completed by participants immediately following an office-based endoscopic procedure and before discharge from the clinic. 

Thirty-five consecutive patients undergoing office-based outpatient endoscopic sinus surgery for chronic rhinosinusitis were assessed. All participants agree or strongly agree that they were satisfied with their anesthesia care and would want the same anesthetic again. No participant required narcotic analgesia, and 80% used no oral analgesia following the procedure.

The study concluded that the recent advances in office-based endonasal surgical procedures must be accompanied by assessing and validating local anesthetic techniques. The described novel lateral nasal wall block is well tolerated, provides patient satisfaction and allows for limited use of postprocedure oral analgesics.
