Function-Centered Strategy Reported in 67 Facial Nerve Schwannoma Surgeries
A retrospective review of 67 surgeries in 61 patients evaluated a strategy that selected nerve preservation or reconstruction according to preoperative facial function and intraoperative electromyography. Facial function improved or remained stable in 87.2% of nerve-preservation cases, although 27.7% later required additional treatment.
- Retrospective review included 67 surgeries in 61 patients.
- Nerve preservation was used in 47 cases.
- Function improved or remained stable in 87.2% of preservation cases.
- 27.7% of preservation cases required additional treatment.
Facial nerve schwannomas are rare benign tumors, and choosing surgery requires balancing tumor control against preservation of facial function. This retrospective series reviewed 67 consecutive surgeries in 61 patients performed from 2004 through 2022. The surgical approach was selected using preoperative facial nerve function and intraoperative electromyography (EMG): nerve-preserving surgery involved nonradical tumor removal or bony decompression, while reconstruction followed total tumor removal in patients with severe or complete palsy.
Nerve-preserving surgery was used in 47 cases (70.1%); facial function improved or remained stable in 87.2% of these cases. Mean House-Brackmann grade improved from 3.5 to 3.0 in the preservation group and from 4.6 to 4.0 in the reconstruction group. Across the series, function improved in 50.7% and worsened in 13.4%. In the preservation group, tumors confined to the temporal bone, younger age, and favorable EMG responses were associated with better postoperative function. During a mean follow-up of 87.2 months, 27.7% of preservation cases required additional treatment.
The findings support a function-centered framework for individualizing surgery, but the study was a retrospective, single-series review and does not establish comparative effectiveness. The authors’ results may help inform surgical planning; they do not establish that this approach is superior to alternatives.
In practice
For patients undergoing surgery for facial nerve schwannoma, this retrospective series describes selecting nerve-preserving surgery or tumor removal with reconstruction according to preoperative facial function and intraoperative EMG. Facial function improved or remained stable in 87.2% of nerve-preservation cases, but 27.7% required additional treatment during follow-up. These results may inform surgical planning, but the uncontrolled retrospective series does not show that this strategy is superior to other approaches or establish a universal treatment threshold.
