PURPOSE: We report 2 cases treated with bilobed flap surgery for medial canthal reconstruction. METHODS: Two patients with black and painless lid mass, 1 x 1 cm size, developed at medial canthal area were excised, and medial canthal reconstruction was performed. Biopsy was done before the surgery, showing basal cell carcinoma. We designed and rotated bilobed flap to reconstruct medial canthal defect caused by the radical excision, and sutured it at the incision margin of the skin. RESULTS: Pathologic examination was done after the surgery, confirming basal cell carcinoma. No marginal cancer cell were detected. Cancer relapse did not occur during 12 months of follow-up. We obtained satisfactory results in all patients, not only clinically but also cosmetically. CONCLUSIONS: It is considered that the bilobed flap procedure is effective for reconstruction of medial canthal defect developed after eyelid tumor excision and offer a good prognosis.

Nerve conduction studies help delineate the extent and distribution of the neural lesion. The nerve conduction was studied on upper (median, ulnar and radial nerves) and lower (personal, posterior tibial and sural nerves) extremities in 83 healthy subjects 23 to 66 years of age, and normal values were established (Table 1). The mean motor terminal latency (TL): median, 3.6 (±0.6) milliseconds; ulnar, 2.9 (±0.5) milliseconds; radial nerve, 2.3 (±0.4) milliseconds. Mean motor nerve conduction velocity (MNCV) along distal and proximal segments: median, 61.2 (±9.1) (W-E) and 57.8 (±13.2) (E-Ax) meters per second; ulnar, 63.7 (±9.1) (W-E) and 50.6 (±10.0) meters per second. Mean sensory nerve conduction velocity (SNCV): median, 34.7 (±6.7) (F-W), 63.7 (±7.1) (W-E) and 62.8 (±12.3) (E-Ax) meters per second; ulnar, 38.0 (±6.7) (F-W), 63.4 (±7.5) (W-E) and 57.0 (±10.1) (E-Ax) meters per second; radial, 45.3 (±6.8) (F-W) and 64.2 (±11.0) (W-E) meters per second; sural nerve, 43.4 (±6.1) meters per second. The amplitudes of action potential and H-reflex were also standardized. Mean H latency was 28.4 (±3.2) milliseconds. And, the fundamental principles, several factors altering the rate of nerve conduction and clinical application of nerve stimulation techniques were reviewed.
