Accessing the anterolateral wall of the maxillary sinus was documented with a straight stereotactic navigator probe at the level of the nasal floor and of the axilla of the inferior turbinate.<\/jats:p><jats:p>Results\u2003At level of the nasal floor, the prelacrimal approach, the modified endoscopic Denker approach, and the endoscopic Denker approach allowed mean radial access to the anterolateral maxillary sinus wall of 42.6\u2009\u00b1\u20097.3 (95% confidence interval [CI]: 39.9\u201345.3), 56.0\u2009\u00b1\u20096.1 (95%CI: 53.7\u201358.3), and 60.1\u2009\u00b1\u20096.2 (95%CI: 57.8\u201362.4), respectively. Furthermore, these approaches provided more lateral access to the maxillary sinus at the level of the axilla of the inferior turbinate, with mean radial access of 45.8\u2009\u00b1\u20096.9 (95%CI: 43.3\u201348.4) for the prelacrimal approach, 59.8\u2009\u00b1\u20094.7 (95% CI:58.1\u201361.6) for the modified endoscopic Denker approach, and 63.6\u2009\u00b1\u20095.5 (95%CI: 61.6\u201365.7) for the endoscopic Denker approach. The mean radial access in each corridor, either at the level of the nasal floor or the axilla of the inferior turbinate, showed a statistically significant difference in all comparison approaches
