Abstract
Background: Various armamentarium used for intraoral incisions in maxillofacial surgery ranges from simple
scalpel to lasers, electrosurgical tip. Few of them have disadvantages such as being non hemostatic, requiring
training or which are costly and are sophisticated. The quest for a better tool for intraoral incisions has lead to the
use of Colorado microdissection needle which achieves hemostasis, requires less equipment and easy to handle.
Aim: To evaluate the effectiveness of the Colorado microdissection needle over the scalpel during intraoral
incisions for impacted mandibular third molar surgery.
Methods and Materials: A total of 30 patients were randomly categorized into the Group A using Scalpel and
Group B using Colorado microdissection needle for Terrance ward’s Incisions. The parameters assessed were
Incision time, Quantity of blood loss, Wound healing on 7th and 14th postoperative day. Statistical analysis used
were a parametric independent – T test and a non-parametric test (Mann-Whitney U test).
Results:The results showed that, apart from wound healing there was no statistically significance difference in
incision time and blood loss between the groups.
Conclusion:The Colorado microdissection needle can be used as an alternative for incisions, as it appears to cause
less tissue damage while providing tissue healing comparable to that of a scalpel.
