Simple Interrupted and Continuous Interlocking Suturing Techniques Comparison in Maxillofacial Trauma – A Randomized Controlled Trial

Aim: To compare the efficacy of simple interrupted and continuous interlocking suturing techniques using 3-0 vicryl (polyglactin) sutures. Method: The study sample included 20 patients (16 males and four females) with maxillofacial trauma requiring ORIF (Open Reduction and Internal Fixation) of maxilla or mandible fractures. They were randomly allocated to two groups (Group A and Group B). Patients in the age group of 20-50 years, requiring ORIF under local anesthesia or general anesthesia through an intraoral approach and incision measuring 4-6 cm were included in the study. Exclusion criteria included patients requiring extra-oral incisions, comminuted fractures with acute illness, infection, pregnancy, immune compromised conditions and patients not willing to participate in the study. Surgical site was closed in single layer using 3-0 vicryl sutures. Intraoperatively, time taken for suturing, wound dehiscence and wound healing were monitored on third, seventh and 30th day post-operatively. Results: In terms of time taken for suturing, dehiscence of wound and wound healing, continuous interlocking sutures showed superior results than that of simple interrupted sutures. Conclusion: Even though simple interrupted suturing is an easy technique, continuous interlocking suturing technique showed superior results. However, surgeons operating maxillofacial trauma may have their own point of view and selection of technique depends on individual preferences.
