Surgical timing for facial paralysis after temporal bone trauma

Area of Science:

• Neurosurgery
• Traumatology
• Otolaryngology

Background:

• Facial paralysis following temporal bone trauma presents a significant clinical challenge.
• Surgical intervention, such as subtotal facial nerve decompression, is a common treatment modality.

Purpose of the Study:

• To investigate the optimal timing for surgical intervention in cases of facial paralysis secondary to temporal bone trauma.
• To evaluate the influence of patient age and paralysis onset on surgical outcomes.

Main Methods:

• Retrospective analysis of clinical data from 80 patients with facial paralysis post-temporal bone trauma.
• Patients underwent subtotal facial nerve decompression and were followed for one year.
• Subgroup analysis based on age, onset, and interval between paralysis and surgery.

Main Results:

• Overall good recovery (HB Grade I or II) was achieved in 65.0% of patients.
• No significant differences in recovery rates were observed between younger and elderly patients, or between immediate and delayed onset groups.
• Surgical decompression within 1 month showed a statistically higher good recovery rate compared to intervals of 3-6 months or >6 months (P<0.05).

Conclusions:

• Surgical timing is a critical factor for favorable facial nerve recovery after temporal bone trauma.
• Early surgical decompression, ideally within 3 months, is recommended for better outcomes.
• Age and onset of paralysis do not appear to be significant predictors of recovery success.
