Hypoglossal nerve paralysis following tonsillectomy

Abstract: While tonsillectomy is the commonest operation performed by otolaryngologists, paralysis of the hypoglossal nerve following tonsillectomy is not well recognized in the otolaryngology text or literature. We report a case of hypoglossal nerve paralysis following tonsillectomy and discuss the theories on the pathoaetiology as described in the predominantly anaesthetics literature. The likely causes of nerve injury are described and precautions are suggested to help avoid this problem.

“…During reresection for positive margins, the airway was lost on one patient necessitating an operative cricothyrotomy. One patient developed bilateral hypoglossal nerve paresis, a documented stretch‐related complication of endoscopic approaches to the pharynx (e.g., tonsillectomy) 14. Nine patients demonstrated postoperative velopharyngeal incompetence, although none severe enough to prevent oral intake or good speech intelligibility.…”

“…10 Clinical Relevance of Peripheral Hypoglossal Nerve Injury Rapid and accurately adjusted tongue movements are paramount for a wide range of functions, including breathing, swallowing, licking/mastication, gaping, gagging, coughing, sneezing, vocalization, and vomiting. 15,33,34 Although hypoglossal nerve injury has anecdotally been considered rare, lesions may result from tumors, 35 trauma, 36 tonsillectomy, 37 anterior cervical spinal surgery, 38 orotracheal intubation, 39 carotid end-arterectomy, 40,41 and use as donor tissue for facial reanimation surgery. 16 Unilateral hypoglossal damage is considered clinically to be well tolerated due to preservation of taste and tactile sensitivity.…”

“…There are also reports of carotid and vertebral artery dissections leading to hypoglossal nerve injury. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] In a large case series of hypoglossal nerve palsies, the site of the lesion could not be localized in 6%. 9 In the radiologic diagnostic work-up, a segmental imaging approach is advised.…”
