Dermatome Mapping Classification<br />

Traditionally, in the era when recurrence was our main concern,<br />

chronic postoperative inguinal pain had been referred to using the<br />

general term “ inguinodynia” for all possible types <strong>of</strong> inguinal pain<br />

manifestations. However, the variation <strong>of</strong> clinical presentations and<br />

etiologies necessitates that we broaden and deepen our understanding <strong>of</strong><br />

this complex condition [ 16 ]. Primarily, it is important to establish the<br />

origin <strong>of</strong> the pain and to classify the location and type <strong>of</strong> pain that we are<br />

dealing with: neuropathic (follows the pattern <strong>of</strong> a dermatome <strong>of</strong> specific<br />

nerve trunks), nociceptive (non- neuropathic), or paresthesias (denervation<br />

or discomfort due to incidental or therapeutic neurectomy).
