Healing II: Complications01:24

Healing II: Complications

Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...

Tonsillitis II: Management

This lesson will focus on the different treatment options for managing tonsillitis, which typically depend on the cause and severity.
Teeth01:15

Teeth

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

Area of Science:

  • Oral and Maxillofacial Surgery
  • Surgical Complications
  • Patient Safety

Background:

  • Orthognathic surgery is complex, with potential for intraoperative and postoperative complications.
  • Evaluating complication rates and associated factors is crucial for improving surgical techniques and patient outcomes.

Purpose of the Study:

  • To evaluate the incidence and types of complications in orthognathic surgery.
  • To identify potential correlations between patient demographics, surgical procedures, and complication occurrence.

Main Methods:

  • Retrospective analysis of 183 orthognathic surgeries performed between 2014 and 2024.
  • Data collection included patient records, surgical procedures (monomaxillary/bimaxillary), and specific complication types.
  • Statistical analysis compared complication rates against variables like age, sex, and substance abuse.

Main Results:

  • A total of 31 complications were recorded (10 intraoperative, 21 postoperative) among 183 surgeries.
  • No statistically significant correlation was found between evaluated variables (age, sex, substance abuse) and complication occurrence (P>0.05).
  • Common complications included bad splits, recurrence, and hardware failure.

Conclusions:

  • While this study found no direct correlation with patient factors, detailed complication analysis is vital.
  • Understanding complication patterns aids surgeons in prevention, early detection, and effective management.
  • Further research may explore other contributing factors to orthognathic surgery complications.
