Voice change can occur after any neck operation, so voice change is sometimes linked to thyroid and parathyroid surgery.
Possible Impact of Thyroid and Parathyroid Surgery
Voice change can effect up to 20% of patients of which 90% is temporary
By temporary I mean it gets better within 6 months.
For around 2% of patients having endocrine surgery the voice change is permanent. In these cases referral to a specialist voice surgeon and speech therapist to discuss options to improve the voice can help.
We take every effort possible to find and protect the recurrent laryngeal nerve during these operations to help protect it. Occasionally, unfortunately this surgery can change your voice quality and strength.
Usually it is due to damage to a nerve running just under the thyroid gland to the voice box. It can make the voice weak and difficult to project. It will also tire quicker than usual so that towards the end of your day it can be harder to speak audibly.
If this has happened to you it is useful to visualize this injury as if you have injured a muscle. When first healing, it likes some rest and then it likes to have activity re-introduced and built up gradually. Follow the same principle for your voice.
In addition to voice change recurrent laryngeal nerve injury can make swallowing feel abnormal. In the very very rare event of both recurrent laryngeal nerves being injured more severe disability can be caused - weaker voice, difficulty swallowing safely and even difficulty breathing requiring a tracheostomy. Remember this is exceptionally rare because such care is taken to protect this nerve. Bilateral nerve injury can only occur after a total thyroidectomy or bilateral neck exploration for parathyroid disease.
