Management of Complications Following TMJ Surgery

Introduction to Complications

The American Association of Oral and Maxillofacial Surgeons recommends that management of complications following TMJ surgery should be tailored to the specific complication, with facial nerve injury requiring observation and potential low-intensity laser therapy, infections demanding early broad-spectrum antibiotics and surgical drainage, and metal hypersensitivity necessitating implant removal and replacement with alternative materials 1, 2

Facial nerve weakness is the most common complication after TMJ replacement, occurring in 7.8% of patients, and is often transient, resolving within 6 months 2
The American Association of Oral and Maxillofacial Surgeons notes that TMJ replacement operations account for 40% of all facial nerve injuries in oral and maxillofacial surgeries, with most cases involving transient weakness of the temporal, buccal, and marginal mandibular branches 1, 2
Revision TMJ replacement surgery carries a higher risk of facial nerve injury due to scar tissue obscuring visualization, and bilateral surgery increases the risk of temporary facial nerve injury 1, 2

The American Association of Oral and Maxillofacial Surgeons recommends that SSI following TMJ replacement be treated with early broad-spectrum antibiotics and surgical drainage within 5 days of symptom onset, with Staphylococcus aureus being the most common organism (53% of cases) 1, 2
The Centers for Disease Control and Prevention guidelines suggest that culture-negative PJI occurs in 27-55% of cases due to biofilms, and that withholding antibiotics before obtaining culture samples can enhance yield 1
The American Association of Oral and Maxillofacial Surgeons notes that administer 7-10 days of oral antibiotic prophylaxis postoperatively due to proximity of surgical wounds to the ear, parotid gland, and oral cavity 1

The American Association of Oral and Maxillofacial Surgeons recommends that metal hypersensitivity be managed by removing the offending implant and considering alternative materials for reconstruction, with metal hypersensitivity developing at any age and having a significantly higher incidence in females 1, 2

The American Pain Society recommends that NSAIDs be used as first-line treatment for pain relief and inflammation reduction, and that strongly avoiding combining NSAIDs with opioids is recommended due to increased risks without clear additional benefits 3, 4

The American Association of Oral and Maxillofacial Surgeons notes that delaying antibiotic therapy and surgical drainage when infection is suspected can lead to poor outcomes, and that assuming all facial nerve weakness is permanent can lead to unnecessary invasive procedures 1, 2
The American Association of Oral and Maxillofacial Surgeons recommends that proceeding to invasive revision procedures before exhausting conservative management options be avoided, and that underestimating the importance of extended culture duration for slow-growing organisms like Propionibacterium acnes can lead to misdiagnosis 1, 5, 4
