Summary
Maxillofacial surgery can cause cardiac dysrhythmias like asystole and bradycardia. This study reports eight cases, highlighting a rare but significant complication in craniofacial procedures.
Area of Science:
- Cardiovascular Surgery
- Oral and Maxillofacial Surgery
Background:
- Cardiac dysrhythmias, including asystole and bradycardia, are known complications of craniofacial and maxillofacial surgery.
- While frequently discussed in ophthalmology, these cardiac events receive less attention in maxillofacial surgery literature.
Purpose of the Study:
- To report on the occurrence of cardiac asystole and bradycardia in patients undergoing maxillofacial surgery.
- To discuss the etiology of these dysrhythmias in the context of specific surgical procedures.
Main Methods:
- Retrospective review of eight patients who experienced cardiac asystole or bradycardia during maxillofacial surgery over a 16-month period.
- Analysis of surgical procedures associated with these cardiac events, including maxillary advancement and temporomandibular joint ankylosis correction.
Main Results:
- Eight patients (1.6% of total) experienced asystole or bradycardia.
- Six events occurred during soft tissue stretching in maxillary advancement.
- Two events occurred during temporalis muscle manipulation for temporomandibular joint ankylosis.
Conclusions:
- Cardiac dysrhythmias are a rare but significant complication in maxillofacial surgery.
- Specific surgical maneuvers, such as soft tissue manipulation during maxillary advancement and temporalis muscle manipulation, may trigger these events.
