Summary
Surgical wound dehiscence (SWD) in intraoral mandibular fracture repair is linked to night-time surgery and smoking. Performing surgery during the day with experienced staff can help avoid SWD.
Area of Science:
- Oral and Maxillofacial Surgery
- Trauma Surgery
- Wound Healing Research
Background:
- Surgical wound dehiscence (SWD) is a potential complication following mandibular fracture repair.
- Understanding non-infection-related causes is crucial for improving patient outcomes.
- Intraoral surgical approaches present unique challenges for wound healing.
Purpose of the Study:
- To investigate the incidence and etiological factors of non-infection-related SWD in patients undergoing intraoral repair of mandibular fractures.
- To identify patient, fracture, and surgical variables associated with SWD.
Main Methods:
- Retrospective study including 232 patients with 270 mandibular fractures treated via an intraoral approach.
- Primary outcome variable was the occurrence of SWD.
- Statistical analysis evaluated associations between various factors and SWD, including time of surgery and smoking status.
Main Results:
- Twenty-two cases of SWD were observed, affecting 9.5% of patients and 8.1% of fractures.
- Night-time surgery demonstrated a significantly higher SWD rate compared to daytime procedures (p=0.012).
- Smokers exhibited a significantly greater SWD rate (p=0.041); multivariate analysis identified night-time surgery as an independent risk factor (OR 3.297).
Conclusions:
- The surgical approach and fracture type had minimal impact on non-infection-related SWD.
- Mandibular fracture surgeries should ideally be performed during daytime hours.
- Ensuring adequate support from experienced surgeons is recommended to minimize the risk of SWD.

271
Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...

01:27Fractures: Bone Repair
3.4K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
