Such damage could be a sign of an underlying disease such as diabetes mellitus, a brain tumor, a pancoast tumor (apex of the lung) and diseases that cause ...
The increase in the risk of nerve injury can be due to the increased vascularity of the thyroid parenchyma and the development of links between the thyroid capsule and the surrounding tissues. Reportedly, a 1% incidence exists of permanent recurrent laryngeal nerve paralysis after complete thyroidectomy. [27]
Ocular neuropathic pain, also called corneal neuralgia, is a spectrum of disorders of ocular pain which are caused by damage or disease affecting the nerves.Ocular neuropathic pain is frequently associated with damaged or dysfunctional corneal nerves, [1] but the condition can also be caused by peripheral or centralized sensitization.
