Purpose: Current advances in equipment technology have offered us with tremendous advantage in performing various
surgeries. Among these is the Colorado electro micro-dissection needle. Although use of electro surgery dates back to 1909 when it
was first used to fulgratetumors, to 1926 when “Cushing” first introduced it in neurosurgery. Its use to open skin has been rejected
or reserved in past for fear of delayed wound healing or infection. Currently there is enough literature and evidence to support
favorable use of electro-cautery as a complete or partial substitution to cold steel, in terms of operative blood loss, post-operative
pain and surgical scar.
Materials and Method: This study clinically evaluated the safety and efficacy of Colorado micro dissection needle over cold
steel in skin incisions in 60 patients undergoing various maxillofacial procedures. The study was done to compare the efficacy
of Colorado micro-dissection needle and cold steel (Scalpel) in oral and maxillofacial surgeries; for post-operative scar (3rd/6th
months), incisional blood loss, post-operative pain and total time taken to complete the length of incision.
Result: The study sample contained 60 patients with ages ranging from 18-60years. Thirty patients were included for Colorado
micro dissection needle group (group I) and 30 for cold steel (Scalpel) group (group II).The average time taken for incision with the
Colorado micro dissection needle was 18.40seconds, as compared to the cold Steel which was 39.63 seconds. The time taken for
incision with Colorado micro dissection needle was less than Cold Steel. Post-operative pain was less when using Colorado micro
dissection needle. In the Colorado micro dissection needle group, mean width of the scar was 1.68 mm per incision at 3rd month
interval and 1.20 mm at 6th month interval per incision. In the Cold Steel group, mean width of the scar was 2.48 mm per incision at
3rd month interval and 2.23 mm per incision at 6th month interval. It was noted that, a Colorado micro dissection needle gives less
width and better scar than Cold steel.
Conclusion: The findings of this study recommend the use of the Colorado micro dissection needle in all maxillofacial procedures.
