Brief summary

To compare the two different suture knot techniques, locked and unlocked, in terms of mean on postoperative trismus and swelling after impacted mandibular third molar surgery.

Detailed description

The rationale behind conducting a comparative analysis of two different suture knot techniques on postoperative trismus and swelling following impacted third molar surgery stems from the imperative need to optimize patient outcomes and improve surgical practices. Impacted third molar surgery, while a routine procedure in oral and maxillofacial surgery, often presents challenges in managing postoperative complications, particularly trismus and swelling, which can significantly impact patients' comfort, recovery, and overall satisfaction.

Interventions

PROCEDURElocking and non locking suture techniques

The participating patients will be randomly assigned into two groups, i.e. receiving locked (L) or unlocked (UL) sutures, using a lottery method. Equal patients will be assigned in both groups. In group L (Locked suturing), the flap will be repositioned and sutured with the locked technique (straight-reverse-straight) hermetically using 3-0 black silk. In group UL (Unlocked suturing), the flap will be repositioned and sutured with the unlocked technique (three straight knots) loosely using 3-0 black silk. Demographic details (including name, age, gender, contact) will be obtained and recorded on specific data collection forms. On the day of surgery before the surgery commences, measurements will be taken for trismus and swelling which will be entered on the data collection form. Trismus will be evaluated by measuring the distance between the mesio-incisal corners of the upper and lower right central incisors at maximum mouth opening in mm, using Castroviejo instrument.

Intervention model description

By undertaking a comparative analysis of two distinct suture knot techniques, this study seeks to address this knowledge gap and provide evidence-based insights into the optimal approach for wound closure in impacted third molar surgery. Understanding the differential effects of suture techniques on postoperative trismus and swelling is essential for informing clinical decision-making, guiding surgical practices, and ultimately enhancing patient care. Postoperative complications are common after this surgery and can be attributed to various factors.

effect of locking and non locking suture technique on trismus3 days and 7 days post operativelyTrismus will be evaluated by measuring the distance between the mesio-incisal corners of the upper and lower right central incisors at maximum mouth opening in mm, using Castroviejo instrument.
Effect of locking and unlocking sutures on facial swellingPost operative day three and day sevenThe facial swelling in cm will be determined by measuring the distance from the corner of the mouth to the attachment of the earlobe following the bulge of the cheek and the distance from the outer canthus of the eye to the angle of the mandible using a plastic measuring tape.
