Hereditary neuropathy with liability to pressure palsies mimicking hypoglossal nerve injuries

16. Swallowing dysfunction in hereditary neuropathy with liability to pressure palsies

“…Carriers are predisposed to focal neuropathies that most frequently involve the brachial plexus and peroneal, ulnar, radial, and median nerves 5,12 . Several authors have reported involvement of the facial, trigeminal, hypoglossal and recurrent laryngeal nerves [3][4][5][6][7][8] . The attacks usually stop within days or weeks and are triggered by compression, slight traction or other minor trauma 1,12 .…”

“…SD are frequent in neurological diseases and may arise from pharyngeal or esophageal dysphagia 17 . Deficits of the lower cranial nerves (nerves IX, X, XI and XII) may cause disabling SD 3 . Pharyngeal dysphagia has previously been reported in HNPP, mainly related to a transient hypoglossal mononeuropathy or associated with recurrent laryngeal nerve palsy 3,6,8 .…”

“…Deficits of the lower cranial nerves (nerves IX, X, XI and XII) may cause disabling SD 3 . Pharyngeal dysphagia has previously been reported in HNPP, mainly related to a transient hypoglossal mononeuropathy or associated with recurrent laryngeal nerve palsy 3,6,8 . Winter and Juel reported an HNPP patient with evident hypoglossal nerve palsy which could partially explain the pharyngeal dysfunction in our patient 8 .…”

“…Winter and Juel reported an HNPP patient with evident hypoglossal nerve palsy which could partially explain the pharyngeal dysfunction in our patient 8 . The weakness in the tongue during swallowing, caused by hypoglossal neuropathy could result in pharyngeal dysfunction with stasis in the pyriform sinuses and valleculae 3,8 .…”

“…Involvement of the cranial nerves has rarely been described in these patients [3][4][5][6][7][8] . Reports of swallowing dysfunction in patients with HNPP are even rarer.…”
