Tapia’s Syndrome (Concurrent Unilateral Recurrent Laryngeal and Hypoglossal Nerve Palsy) Following Left Retrosigmoid Craniotomy for Schwannoma Resection

Tapia’s syndrome, a unilateral, extracranial combined lesion to the hypoglossal nerve (cranial nerve [CN] XII) and the recurrent laryngeal branch of the vagal nerve (CN X), has been observed to occur after general anesthesia for a variety of surgical procedures.

Sumario:Tapia’s syndrome, a unilateral, extracranial combined lesion to the hypoglossal nerve (cranial nerve [CN] XII) and the recurrent laryngeal branch of the vagal nerve (CN X), has been observed to occur after general anesthesia for a variety of surgical procedures. Surgical intraoperative neck positioning and airway management are hypothesized as causative factors. The condition presents with ipsilateral motor paralysis of the tongue and vocal cords. Postoperatively, patients often present with dysphonia, dysphagia, and difficulty swallowing. We discuss a unique case of Tapia’s syndrome occurring after retrosigmoid craniotomy for left vestibular schwannoma resection in a 42-year-old male. General anesthesia was uneventful with an atraumatic, grade 2a intubation and a normal endotracheal tube cuff pressure of 30 cm of water. The patient was positioned laterally, even though the exact head position was not documented. Institutional practice in these cases is for the head to be maintained neutral or with a slight turn. An uneventful subtotal resection of the tumor was performed after retrosigmoid exposure. Postoperatively, the patient complained of left-sided mouth tingling, a hoarse voice, and tongue weakness which impacted his ability to chew and swallow. He had mild left-sided facial weakness and decreased sensation in the V1 and V2 distribution of the trigeminal nerve. Postoperative brain MRI showed postsurgical changes without evidence of neurological or vascular involvement. Fiberoptic endoscopy performed in the otolaryngology clinic showed immobility of the right vocal cord. Consequently, Tapia’s syndrome was diagnosed. He later underwent a right vocal fold injection with Prolaryn gel (Merz North America, Inc, Greensboro, NC, USA) via flexible laryngoscopy with a slight improvement in his dysphonia. At his last visit, he declined further interventions based on acceptable voice quality. Tapia’s syndrome can occur due to the close anatomical proximity of the hypoglossal and recurrent laryngeal nerves as they pass lateral to the oropharynx and hypopharynx. This predisposes the nerves to anesthetic and surgical insults such as over-stretching of the nerves during head manipulation and trauma to the nerve fibers following laryngoscopy. Our case report highlights this potential rare complication to anesthetic and surgical teams. Awareness of this concurrent paralysis can assist practitioners to rapidly diagnose and treat patients who present in this way postoperatively. It can also enable avoidance of causative factors and remind practitioners of the importance of meticulous perioperative documentation.
