Abstract
Vocal fold paralysis occurs when the function of the vagus nerve or its distal branch, the recurrent laryngeal nerve, is diminished or absent. Bilateral vocal fold paralysis can present with varying degrees of severity and is sometimes fatal. Cervical osteophytes are a rare cause of bilateral vocal fold paralysis, with only a few cases reported. A 68-year-old man was brought to the emergency department because of a disturbance in consciousness following a fall. A CT scan of the head showed multiple cranium and brain injuries, and the patient was treated conservatively by neurosurgery. The day after the injury, dysphagia and dysarthria appeared. On the third day of admission, both vocal cords were fixed bilaterally in the paramedian position, and the patient was nearly choking on sputum. A CT scan showed that the intracranial lesions gradually improved, but the vocal cord paralysis remained. A cervical CT scan was performed to investigate the cause of the vocal cord paralysis, which revealed that cervical vertebral osteophytes were compressing the tracheoesophageal groove and the glottis. The patient was transferred to the hospital for rehabilitation, although bilateral vocal cord paralysis remained. Although rare, clinicians need to be aware that cervical osteophytes can cause vocal fold paralysis, which may be manifested when combined with further trauma. It is also important to note that traumatic vocal cord paralysis can be delayed.

Abstract
Bilateral vocal cord paralysis is a potentially life-threatening condition, depending on the position in which the vocal cords are paralyzed. When the vocal cords are fixed in adduction, patients develop respiratory distress, inspiratory stridor, aspiration, and minimal phonation deficits. This condition can result from acute injuries to the right and left recurrent laryngeal nerves, or from chronic bilateral recurrent laryngeal nerve palsy. The clinical presentation is variable with such nerve injuries. Traumatic injuries to the cervical spine are an uncommon cause of this condition. In this report, we describe a patient who developed progressive respiratory distress, inspiratory stridor, and dysphagia to liquids several weeks after suffering major trauma to the head and neck. Laryngoscopy revealed immobile bilateral vocal cords fixed in the paramedian position, resulting in severe airway obstruction that warranted an emergency tracheostomy.

Abstract
Injury of lower cranial nerves (CNs) by skull base fracture after head trauma can occur sometimes. However, selectively different CN damage on either side is extremely rare. A 53-year-old man had difficulty of swallowing, phonation, and articulation after falling off his bicycle. In physical examination, a deviated tongue to the right side was shown. Brain computed tomography showed a skull base fracture involving bilateral jugular foramina and right hypoglossal canal. Left vocal cord palsy was confirmed by laryngoscopy. Electromyography confirmed injury of left superior laryngeal nerve, recurrent laryngeal nerve, and right hypoglossal nerve. Video fluoroscopic swallowing study revealed large amounts of remnant in vallecula and pyriform sinus without opening of upper esophageal sphincter due to dysfunction of cricopharyngeus muscle. After constant rehabilitation for dysphagia, he was allowed to eat a general diet with compensatory techniques at discharge and further recovery after 3 months. Injury of lower CNs after fracture of the skull base can cause severe morbidity. However, the prognosis of such injuries can be favorable with early rehabilitation treatment by identifying the injured CN. A careful and accurate examination of lower CN injury in skull base fracture is essential for planning a treatment strategy.

Abstract
A 63-year-old man collided with a vehicle while riding a motorcycle. At an emergency hospital, he was diagnosed with cerebral concussion, incomplete cervical cord injury, C6 fracture, facial bone fractures, and lacerations. Radiographical findings indicated that his neck was forced into an extended position. At our rehabilitation hospital, we evaluated the patient’s hoarseness and dysphagia 1 month posttrauma and determined the diagnosis to be due to “traumatic right recurrent laryngeal nerve palsy (RLNP).” We followed the patient’s RLNP during admission and at our outpatient clinic. His right RLNP gradually recovered and finally disappeared 6 months after the accident. We describe this case within the context of a review of the literature.

Abstract
Occipital condylar fractures (OCFs) causing delayed onset lower cranial nerve paralysis (LCNPs) are rare. We present a 7‐year‐old Friesian horse with delayed onset dysphagia caused by vagus nerve (CNX) paralysis and suspicion of glossopharyngeal nerve (CNIX) paralysis developed several days after a minor head injury. Endoscopic examination revealed right laryngeal hemiplegia and intermittent dorsal displacement of the soft palate. An area of submucosal hemorrhage and bulging was appreciated over the dorsal aspect of the medial compartment of the right guttural pouch. Radiological examination of the proximal cervical region showed rotation of the atlas and the presence of a large bone fragment dorsal to the guttural pouches. Occipital condyle fracture with delayed onset cranial nerve paralysis was diagnosed. Delayed onset cranial nerve paralysis causing dysphagia might be a distinguishable sign of OCF in horses. Delayed onset dysphagia after head injury should prompt equine clinicians to evaluate the condition of the atlanto‐occipital articulation and skull base.

Quantification of Surgical Route Parameters for Exposure of the Jugular Foramen Via a Trans-Mastoidal Approach Exposing Jugular Foramen in Three-Dimensional Visualization Model. J Craniofac Surg 2018; 29:787-791.

Abstract
OBJECTIVE Surgical operation within the region of the jugular foramen presents a great challenge. The authors characterized the quantitative impact of surgical window parameters on the exposure of the jugular foramen via a trans-mastoidal approach. METHODS Computed tomography and magnetic resonance imaging data were used to establish a 3-dimensional model of the jugular foramen region. The mastoidale, posterior edge of the mastoid, and the superior edge of the bony external acoustic meatus were selected as points a, b, and c. The anterior edge of the tuberculum jugulare was selected as point d. The midpoints of line segments ab, ac, and bc were selected as points e, f, and g. Triangle abc was divided into triangles aef, beg, cfg, and efg. Surgical corridors of the triangular pyramid were outlined by connecting the above triangles to point d. Anatomic exposure was evaluated by measuring the area and volume of various structures within each route. Statistical comparisons were performed via analysis of variance. RESULTS The model allowed for adequate visualization of all structures. The areas of triangles beg and efg were greater than those of triangles aef and cfg (P < 0.05). The volumes of triangular pyramids d-beg and d-cfg were greater than those of triangular pyramids d-aef and d-efg (P = 0.000). Statistically significant differences were also observed for volumes of osseous, venous, and cranial nerve structures in all divided routes (P = 0.000). CONCLUSION Our results indicate that 3-dimensional modeling may aid in the quantification of surgical exposure and that division of the craniotomy window may allow for more precise operation.

Abstract
Paralysis of the lower cranial nerves is uncommon after closed head injuries. Most cases reported are unilateral and associated with base of skull fractures, usually involving the occipital condyles. Bilateral lower cranial nerve palsy is even less common, with only a handful of cases reported in literature. A 17-year-old girl presented to us after she was involved in a side-on collision with a car while driving a scooter. She sustained traumatic brain injury requiring mechanical ventilation. Detailed neurological evaluation revealed bilateral paralysis of the IXth, Xth, and XIIth cranial nerves with no evidence of a fracture of the base of skull or brain stem injury. A traction type of injury to the nerves arising from a whiplash mechanism may have led to paralysis of the lower cranial nerves in our patient. An exhaustive review of literature revealed 11 reports of bilateral lower cranial nerve palsy associated with closed head injuries; there were only four cases without underlying fracture of the occipital condyles. Our patient made a complete recovery over a period of 4 months. A traction type of injury to the lower cranial nerves may occur due to a whiplash mechanism. This type of injury may be associated with a favorable outcome.
