Hemorrhagic Complications in Implant Surgery: A Scoping Review on Etiology, Prevention, and Management

Area of Science:

• Oral and Maxillofacial Surgery
• Dental Implantology
• Surgical Complications

Background:

• Bleeding complications, including hemorrhage and hematoma, are significant risks in routine dental implant surgery.
• Understanding the etiology and management of these events is crucial for patient safety and successful outcomes.

Purpose of the Study:

• To systematically review and synthesize evidence on the causes, prevention, and management of bleeding during routine implant surgery.
• To provide a comprehensive overview of relevant clinical manifestations and treatment strategies.

Main Methods:

• A systematic electronic literature search was performed across major databases (MEDLINE, EMBASE, Cochrane) up to June 2021.
• Eligibility criteria focused on human studies reporting bleeding associated with routine implant surgery.
• A scoping review methodology was employed, including 20 reviews and 41 case reports.

Main Results:

• The majority of bleeding complications occurred in the mandibular region, particularly the canine area, often involving sublingual and submental arteries due to lingual cortical plate perforation.
• Clinical manifestations included swelling, floor of mouth/tongue elevation, and potential airway obstruction, requiring interventions like intubation or tracheostomy.
• Management strategies ranged from conservative measures (compression, hemostatic agents) to surgical ligation or angiographic embolization for persistent hemorrhage.

Conclusions:

• Effective management of bleeding in implant surgery requires prompt recognition of potential risks and implementation of appropriate interventions.
• Prevention strategies targeting vulnerable anatomical areas and vessels are essential.
• A multi-faceted approach, from conservative first aid to advanced surgical and interventional techniques, is necessary for controlling implant surgery-related hemorrhage.
