Aim:
To evaluate whether the use of electrothermal bipolar vessel sealing system reduces the blood loss and operating time, with lesser complications as compared to suture ligation in selective neck dissection in patients with oral cancer.
Materials And Methods:
The study was conducted in the Department of Oral and Maxillofacial Surgery of our institute from January 2015 to December 2016. The sample consisted of 60 patients, divided into Groups I and II with 30 subjects in each. In Group I electrothermal bipolar vessel sealer and in Group II suture ligation were used. The outcome measures recorded were: blood loss, operating time, quality of surgical field, postoperative pain on days 1, 2, and 3, drainage volume at 24, 48, and 72 h, edema, complications, and duration of hospital stay.
Results:
There were 36 males and 24 females with a mean age of 50.76 ± 12.6 years. Blood loss was significantly less for Group I than for Group II (p = 0.001); the operating time was significantly less in Group I than in Group II (p = 0.001); Group I had better quality of surgical field (p = 0.001); less pain on postoperative evening, day 2 and day 3 (p < 0.05); and less drainage volume at 24 and 48 h (p < 0.05). Postoperative edema, complications, need for perioperative blood transfusion, and duration of hospital stay postsurgery were similar in both groups.
Conclusion:
The electrothermal bipolar vessel sealer was efficacious in terms of reducing blood loss and operating time while providing a better surgical field and patient compliance without increasing the perioperative morbidity.

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
