Objectives: Whitnall’s tubercle (WT) is located deep in the lateral canthus and on orbital wall has crucial structures attach to it. We aimed define location of WT using palpable bone landmarks which can be used as reliable eyelid surgery prevent damage stuctures associated with WT. Methods: Forty-four adult skulls (22 right, 22 left) were included study. The divided into two groups according apparancy distances from frontozygomatic suture, marginal tubercle, anterior point zygomatic arch, margin orbit measured. clock positions arc determined. Results: orbit, suture 9.92±1.65 mm, 16.48±1.86 2.32±0.53 mm 9.66±1.44 respectively. was at 8 9 o’clock left, 4, 3, 2 right tubercle. 10 position 1 arch. Conclusion: arch standart bony soft tissue relevant high kappa values interclass intraclass correlations suggest that these parameters are repeatable for clinical use. Out parameters, more beneficial locate because standard positions. typically left
