Prolonged dysphonia after anterior cervical surgery is mostly due to paralysis of a nerve know as recurrent laryngeal nerve.
patients with recurrent laryngeal nerve palsy also recover over time with minimal residual dysphonia.
If prolonged dysphonia is present then usually a ENT Surgerons reference is warranted to confirm that there is a vocal cord paralysis treatment –which might range from conservative to operative.
This is a wonderful resource to know every thing about laryngeal nerve paralysis
For Spine surgeons- How to prevent nerve paralysis
– minimally invasive
– try posterior approaches in singers
– less extensive retraction – one level at a time
– deflation of the endotracheal tube while application of the cervical retraction and then reinflation
– using hand held retractors instead of self retaining ones
– using left sided approach
– longus coli should be dissected cleanly from the middling and the retractor should engage the longus coli
