Objective To determine the two‐dimensional (2D) characteristics of flaps necessary to create three‐dimensional (3D) tongue anatomy. Methods Dissection of 11 fresh, nonpreserved human cadavers was performed. Six defects in each were created: total tongue, total oral tongue, hemiglossectomy, oral hemiglossectomy, total base of tongue, and hemi‐base of tongue. The resections were debulked to create flat, 2D mucosal flaps. The dimensions and shapes of these flaps were determined. Results Each specimen showed consistent dimensions and geometry between cadavers. The total tongue was pear‐shaped, the total oral tongue was egg‐shaped, the oral hemi‐tongue was bullet‐shaped, the hemi‐tongue resembled a dagger, the total base of tongue was rectangular, and the hemi‐base of tongue was hour‐glass shaped. Conclusion Typical dimensions and shapes of common tongue defects were determined. It is conceivable that customizing reconstructive flaps based on these data will increase the accuracy of neo‐tongue reconstruction, and thus, improve functional outcomes.
