Table 1 Three topographic patterns based on distance between the external branch of the superior laryngeal nerve (eSLN) and the apical pole (AP) of the thyroid gland.
From: Anatomy of the external branch of the superior laryngeal nerve in Asian population
Vertical location of the eSLN | Korean specimens | Thai specimens | All specimens | |
|---|---|---|---|---|
Over the AP | >1 cm Distance | 27.8% | 27.3% | 27.6% |
<1 cm Distance | 55.5% | 45.4% | 51.7% | |
Under the AP | 16.7% | 27.3% | 20.7% | |
Total | 100% | 100% | 100% | |
