Figure 1a.

Capsular dissection of a parotid pleomorphic adenoma. Note the cuff of tissue on top of the tumour to aid safe manipulation. The dissection plane is the capsule of the tumour.

Figure 1b.

Please note the difference between capsular and extracapsular dissection. In the latter, the dissection proceeds a few millimetres away from the capsule which is not exposed unless a facial nerve branch is identified.
