| Three superimposed planes can be distinguished, corresponding to the three venous networks: dermal, subdermal, and subaponeurotic. |
| Both of these systems are connected to dermal and subdermal networks by direct or indirect perforating veins, often with multiple branches. |
| Disposable subdermal needle electrodes are available in both a straight version and with hook. |
| The subdermal tissue of the eyelid is also very different from the usual hypodermis, as it does not contain adipose cells. |
| They are usually related to excess pressure in a subdermal or intramuscular venous trunk. |
| But for the most part that's the extent of the pain, this subdermal unease. |
