A Novel Option for Revision Medialization: Repeat Reinnervation.

ABSTRACT

Nonselective laryngeal reinnervation (NSLR) shows comparable voice results to thyroplasty after one year without permanent implants. In the rare case of a second ipsilateral vocal fold paralysis after NSLR, we present the first recorded revision NSLR. Case report. A 51 year old woman with a history of right NSLR in 2017 for vocal fold paralysis after an anterior cervical diskectomy and fusion (ACDF) presented for re-evaluation prior to a revision of her ACDF. Ipsilateral revision was recommended to reduce the risk of bilateral vocal fold paralysis. Post-operatively, she was noted to have vocal fold immobility. Her maximum phonation time at that time was 9 s. Her voice was moderately breathy and moderately asthenic. Fundamental frequency (F0) was 211 Hz. Jitter was 2.868%, and shimmer 14.429%. Noise to harmonic ratio was 0.366. Cepstral peak prominence was 2.689. After being offered thyroplasty or revision reinnervation, she opted for revision reinnervation due to a strong preference for her reinnervated voice. She underwent a revision cross-neck NSLR with a commercial nerve graft in September 2022. One year later, her MPT was found to be 7.6 s, with mild breathiness and asthenia. F0 was 190 Hz. Jitter decreased to 2.42%, shimmer to 6.478%, and NHR to 0.165. Cepstral peak prominence increased to 4.427. VHI decreased from 35 pre-operatively to 7 post-operatively. We present the first case of a revision NSLR. Notable improvement has been found in objective voice measures and patient-reported outcomes post-operatively, demonstrating feasibility in similar patients. Laryngoscope, 2024.
