ABSTRACT
Abstract Introduction Upper airway stimulation (UAS) with electric activation of the hypo-glossal nerve has emerged as a promising treatment for patients with moderate-to-severe obstructive sleep apnea. Objective To retrospectively analyze objective and subjective outcome measures after long-term follow-up in obstructive sleep apnea patients receiving upper airway stimulation. Methods An observational retrospective single-center cohort study including a consecutive series of patients diagnosed with obstructive sleep apnea receiving upper airway stimulation. Results Twenty-five patients were included. The total median apnea-hypopnea index (AHI) significantly decreased from 37.4 to 8.7 events per hour at the 12-month follow-up (p < 0.001). The surgical success rate was 96%. Adverse events were reported by 28% of the patients. Conclusion Upper airway stimulation is an effective and safe treatment for obstructive sleep apnea in patients with continuous positive airway pressure (CPAP) failure or intolerance. However, it is possible that the existing in and exclusion criteria for UAS therapy in the Netherlands have positively influenced our results.
ABSTRACT
SUMMARY: Cranial nerve injury is one of the neurologic complications following carotid endarterectomy. The hypoglossal nerve is one of the most frequently injured nerves during carotid endarterectomy. Guidelines suggest that proper anatomic knowledge is crucial to avoid cranial nerve injury. The aim of the present study is to provide landmarks for the localization of the hypoglossal nerve during carotid endarterectomy. 33 anterior cervical triangles of formalin-fixed adult cadavers were dissected. The "carotid axis" was defined and measured, the level of the carotid bifurcation within the carotid axis was registered. "High carotid bifurcation" was considered for those carotid bifurcation found in the upper 25 mm of the carotid axis. The distance between the hypoglossal nerve and the carotid bifurcation was measured (length 1). The relationship between the hypoglossal nerve and the posterior belly of the digastric muscle was registered. For caudal positions, the distance between hypoglossal nerve and posterior belly of the digastric muscle was determined (length 2). Carotid axis range 88.3 mm-155.4 mm, average 125.8 mm. Level of the carotid bifurcation within the carotid axis range 75.3 mm-126.5 mm, mean 102.5 mm. High carotid bifurcation was found in 19 cases (57 %). Length 1 ranged from 1.6 mm to 38.1, mean 17.5. Finally, in 29 specimens (87.8 %) the hypoglossal nerve was caudal to posterior belly of the digastric muscle, whereas in 4 cases (12.2 %) it was posterior. Length 2 ranged from 1 mm to 17.0 mm, mean 6.9 mm. Distances between the hypoglossal nerve and nearby structures were determined. These findings may aid the surgeon in identifying the hypoglossal nerve during carotid endarterectomy and thus prevent its injury.
RESUMEN: La lesión de pares craneales es una de las complicaciones neurológicas posteriores a la endarterectomía carotídea. El nervio hipogloso es uno de los nervios lesionados más frecuentemente durante la endarterectomía carotídea. Las guías de actuación clínica sugieren que el conocimiento anatómico adecuado es crucial para evitar lesiones de los nervios craneales. El objetivo del presente estudio fue proporcionar puntos de referencia para la ubicación del nervio hipogloso durante la endarterectomía carotídea. Se disecaron 33 triángulos cervicales anteriores de cadáveres adultos fijados en solución a base de formaldehído. Se definió y midió el "eje carotídeo", se registró el nivel de la bifurcación carotídea dentro del eje carotídeo. Se consideró una "bifurcación carotídea alta" para aquellas bifurcaciones carotídeas encontradas en los 25 mm superiores del eje carotídeo. Se midió la distancia entre el nervio hipogloso y la bifurcación carotídea (longitud 1). Se registró la relación entre el nervio hipogloso y el vientre posterior del músculo digástrico. Para las posiciones caudales, se determinó la distancia entre el nervio hipogloso y el vientre posterior del músculo digástrico (longitud 2). Rango del eje carotídeo 88,3 mm-155,4 mm, media 125,8 mm. Rango del nivel de la bifurcación carotídea dentro del eje carotídeo 75,3 mm-126,5 mm, media 102,5 mm. Se encontró una bifurcación carotídea alta en 19 casos (57 %). La longitud 1 osciló entre 1,6 mm y 38,1, con una media de 17,5. Finalmente, en 29 muestras (87,8 %) el nervio hipogloso fue caudal al vientre posterior del músculo digástrico, mientras que en 4 casos (12,2 %) fue posterior. La longitud 2 osciló entre 1 mm y 17,0 mm, con una media de 6,9 mm. Se determinaron las distancias entre el nervio hipogloso y las estructuras cercanas. Estos hallazgos pueden ayudar al cirujano a identificar el nervio hipogloso durante la endarterectomía carotídea y así prevenir su lesión.

Introduction The side-to-end hypoglossal-facial anastomosis (HFA) technique is an excellent alternative technique to the classic end-terminal anastomosis, because itmay decrease the symptoms resulting from hypoglossal-nerve transection. Methods Patients with facial nerve palsy (House-Brackmann [HB] grade VI) requiring facial reconstruction from 2014 to 2017were retrospectively included in the study. Results In total, 12 cases were identified, with a mean follow-up of 3 years. The causes of facial paralysis were due to resection of posterior-fossa tumors and trauma. There was improvement in 91.6% of the patients (11/12) after the HFA. The rate of improvement according to the HB grade was as follows: HB III - 58.3%; HB IV - 16.6%; and HB II - 16.6%. The first signs of improvement were observed in the patients with the shortest time between the paralysis and the anastomosis surgery (3.5months versus 8.5 months; p » 0.011). The patients with HB II and III had a shorter time between the diagnosis and the anastomosis surgery (mean: 5.22 months), while the patients with HB IV and VI had a longer time of paresis (mean: 9.5 months; p » 0.099). We did not observe lingual atrophy or changes in swallowing. Discussion and Conclusion Hypoglossal-facial anastomosis with the terminolateral technique has good results and low morbidity in relation to tongue motility and swallowing problems. The HB grade and recovery appear to be better in patients operated on with a shorter paralysis time.

Resumen El síndrome de Tapia es una complicación poco frecuente secundaria a la manipulación de la vía aérea. Se caracteriza por haber una lesión concomitante de los pareas craneales X (nervio vago) y XII (nervio hipogloso), usualmente por compresión o sobredistensión de estos. Inicialmente puede hacernos sospechar una lesión central, al haber compromiso de dos nervios craneales bajos en forma simultánea, pero la gran mayoría de los casos descritos son lesiones periféricas. De los procedimientos asociados a esta complicación, los que lideran en frecuencia son los de cabeza y cuello, por lo que es de gran importancia tenerlo en conocimiento en el desarrollo de nuestra práctica clínica. Nuestro paciente presentó esta complicación tras una septoplastía con turbinectomía sin complicaciones en el sitio operatorio, ni anestésicas. Se manejó con fonoaudiología y corticoides orales, con recuperación completa a los cuatro meses de posoperatorio.
Abstract Tapia's Syndrome is a rare complication secondary to airway manipulation. It is characterized by a concurrent lesion of cranial nerve pairs X (vagus nerve) and XII (hypoglossal nerve), usually attributed to compression or stretching of these nerves. Initially, it may lead us to suspect a central lesion, as there is simultaneous involvement of two low cranial nerves, but the vast majority of cases described are peripheral lesions. The procedures most frequently associated with this complication are head and neck surgery, which is why it is very important to bear this in mind in the development of our clinical practice. Our patient showed Tapia's syndrome following septoplasty with turbinectomy without complications in the operative site nor under anesthesia. He was treated with phoniatric and oral corticoids, recovering completely four months after surgery.

ABSTRACT
Los neurofibromas son tumores benignos con origen en la vaina de nervios periféricos; aunque raros, son diagnosticados en pacientes sin historia previa de neurofibromatosis tipo 1, en cuyo caso se constituye en una forma esporádica. Se presenta el caso de un paciente masculino de 27 años con una masa supraclavicular izquierda asintomática de crecimiento progresivo. En la intervención se encontró que la masa tenía origen en el asa del hipogloso.
Neurofibromas are benign tumors that originate from the sheet of peripheral nerves; even though rare, they are occasionally seen in patients with a prior history of neurofibromatosis type1, in which case a sporadic form is diagnosed. A 27-year-old male is described with a left asymptomatic supraclavicular slow growing mass, different of the suspected vagus nerve tumor. In surgery, it was found that the tumor was originating from the Ansa Hypoglossi.

Background: The common carotid, internal and external carotid arteries and their branches serve as major source of blood supply in head-neck region of human and are often encountered during numerous surgical and clinical interventions of neck.Methods: We dissected and examined both sides of neck in 49 well embalmed cadavers (98 sides). We recorded the following anatomical parameters of carotid arterial system-level of bifurcation, the relation between internal and external carotid arteries, branching pattern of anterior branches of external carotid artery, tortuosity in carotid arterial system, and relation of hypoglossal nerve with the carotid arteries.Results: In 56.16 % cases, the common carotid arterial bifurcation took place at the upper border of thyroid cartilage though high bifurcation was quite common (43.88%). The external carotid artery was located antero-medial to internal carotid artery in most cases (93.87%). Abnormal tortuosity of carotid arterial system was detected in 2.04% cases only. In 86.73% cases, the hypoglossal nerve crossed the internal and external carotid artery superior to carotid bifurcation above the level of hyoid bone while in 1 case it crossed immediately inferior to carotid bifurcation. In branching pattern, following variations were observed- linguo-facial trunk in 15.3% cases, thyro-lingual trunk in 5.1% cases, origin of superior thyroid artery from common carotid in 10.02% cases and origin of superior thyroid from internal carotid in one case (1.02%).Conclusions: The carotid arterial system has complex and variable anatomy in neck and this information should be kept in mind to avoid unwanted damage during surgical procedures of neck.
ABSTRACT
BACKGROUND: The laryngeal mask airway (LMAⓇ) Protector™ (Teleflex Medical Co., Ireland) is the latest innovation in the second generation of LMA devices. One distinguishing feature of this device is its integrated, color-coded cuff pressure indicator (Cuff ™ technology) which enables continuous cuff pressure monitoring and allows adjustments when necessary; this ensures patient safety due to better monitoring.CASE: We report a case of postoperative unilateral hypoglossal nerve palsy after uncomplicated use of the LMA Protector. To the best of our knowledge, this could be the second reported case.CONCLUSIONS: This case demonstrates that anesthetists need to routinely measure cuff pressure and that the Cuff Pilot™ technology is not a panacea for potential cranial nerve injury after airway manipulation.

Resumen Se presenta el caso de un paciente masculino de 14 años de edad, con antecedente de dos intervenciones quirúrgicas debidas a la presencia de una masa a nivel sublingual -la primera a los 8 meses de edad y la segunda a los 13 años- y sin información de estudios histopatológicos. Cerca de 8 meses después de la última intervención quirúrgica es valorado por el Servicio de Cirugía Maxilofacial de la Fundación Hospital Pediátrico de La Misericordia en Bogotá D.C., Colombia, por crecimiento acelerado de la misma lesión y por problemas en la deglución y el lenguaje. En la revisión del paciente se encuentra una masa importante sublingual, dificultad en el lenguaje, deformidad mandibular y alteraciones en la mordida, por lo que se decide intervenir quirúrgicamente de nuevo. El resultado de la biopsia es un tumor mesenquimal benigno característico de neurofibroma, que por su ubicación sugiere probable compromiso del nervio hipogloso.
Abstract This article presents the case of a 14-year-old male patient, with a history of two surgical procedures due to the presence of a mass at sublingual level -the first performed at the age of 8 months and the second at 13 the age of years- and without information of histopathological studies. About 8 months after the last surgical procedure, the patient was assessed by the Maxillofacial Surgery Service of the Fundación Hospital Pediátrico de La Misericordia, in Bogotá D.C. - Colombia, due to the rapid growth of the same lesion and swallowing and language disorders. On physical examination, a significant sublingual mass, difficulty in language, mandibular deformity and malocclusion were observed, so a new surgical intervention was indicated. The result of the biopsy revealed a benign mesenchymal tumor, typically seen in neurofibroma, which suggested a possible involvement of the hypoglossal nerve due to its location.
ABSTRACT
Multifocal acquired demyelinating sensory and motor neuropathy (MADSAM) is a peripheral neuropathy characterized by multifocal weakness and associated sensory impairment. MADSAM is associated with multifocal persistent conduction block and other signs of demyelination. The incidence of cranial nerve involvement in MADSAM was recently reported to be approximately 15%. However, reports of hypoglossal neuropathy occurring in MADSAM are rare. Unilateral hypoglossal neuropathy in MADSAM is usually misdiagnosed as motor neuron disease. We report a patient with MADSAM presenting with tongue hemiatrophy.

The hypoglossal nerve (CN XII) may be placed at risk during posterior fossa surgeries. The use of intraoperative monitoring (IOM), including the utilization of spontaneous and triggered electromyography (EMG), from tongue muscles innervated by CN XII has been used to reduce these risks. However, there were few reports regarding the intraoperative transcranial motor evoked potential (MEP) of hypoglossal nerve from the tongue muscles. For this reason, we report here two cases of intraoperative hypoglossal MEP monitoring in brain surgery as an indicator of hypoglossal deficits. Although the amplitude of the MEP was reduced in both patients, only in the case 1 whose MEP was disappeared demonstrated the neurological deficits of the hypoglossal nerve. Therefore, the disappearance of the hypoglossal MEP recorded from the tongue, could be considered a predictor of the postoperative hypoglossal nerve deficits.

Resumen El síndrome de apnea-hipopnea obstructiva del sueño (SAHOS) es una enfermedad caracterizada por la obstrucción recurrente de la vía aérea superior (VAS), con disminución en el flujo de aire, hipoxemia intermitente y despertares durante el sueño. En la fisiopatología del SAHOS se presentan dos factores esenciales: las alteraciones anatómicas y la disminución o ausencia del control neural. Durante el estudio del SAHOS se debe identificar el sitio o sitios de obstrucción de la VAS, que pueden ir desde las alas nasales hasta la hipofaringe. Otro factor importante en este síndrome es el influjo nervioso en el tono muscular de la hipofaringe, así como los cambios en el pH sanguíneo y secundarios a los microdespertares. La posición corporal y el estadio de sueño son factores determinantes de la severidad. La fisiopatología del SAHOS debe ser entendida para poder estudiar de forma adecuada a un paciente y darle la mejor opción de tratamiento.
Abstract Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a disease characterized by recurrent upper airway obstruction (UAO), with decreased airflow, intermittent hypoxemia, and awakening during sleep. Two essential factors are related to the pathophysiology of OSAHS: anatomical alterations and reduction or absence of neural control. While studying OSAHS, the site or sites of obstruction of the UA should be identified; they may extend from the nasal wings to the hypopharynx. Another important factor in this syndrome is the nervous influence on muscle tone of the hypopharynx, as well as the changes in blood pH, which are secondary to micro-arousals. Body position and sleep stage determine the severity. The pathophysiology of OSAHS should be understood to properly study a patient and provide the best treatment option.
ABSTRACT
Collet-Sicard syndrome is a rare syndrome that involves paralysis of 9th to 12th cranial nerves. We report an uncommon case of schwannoma of the hypoglossal nerve in a 39-year-old woman presented with slurred speech, hoarse voice, and swallowing difficulty. Physical examination revealed decreased gag reflex on the right side, decreased laryngeal elevation, tongue deviation to the right side, and weakness of right trapezius muscle. MRI revealed a mass lesion in the right parapharyngeal space below the jugular foramen. The tumor was surgically removed. It was confirmed as hypoglossal nerve schwannoma via pathologic examination. Videofluoroscopic swallowing study revealed aspiration of liquid food and severe bolus retention in the vallecula and piriform sinus. Laryngoscopy revealed right vocal cord palsy. Electrodiagnostic study revealed paralysis of the right 11th cranial nerve. In summary, we report an uncommon case of schwannoma of the hypoglossal nerve with 9th to 12th cranial nerve palsy presenting as Collet-Sicard syndrome.

The etiology and pathogenesis of sleep obstructive apnea hypopnea syndrome (OSAHS) is not yet definitive, evidence shows that the dysfunction of pharyngeal nerve and the atonia of the muscle innervated by these nerve could play an important role in the progress of OSAHS. Dopamine is a neurotransmitter in the central nervous system which significantly affects the sleep-awake regulation. So far mounting evidence shows that dopamine has a potential role in the modulation of hypoglossal nucleus. The progress of dopamine in obstructive sleep apnea hypopnea syndrome is reviewed in this article.
ABSTRACT
Obstructive sleep apnea hypopnea syndrome(OSAHS) is a clinical and critical disease to health, which the accuratly pathogenesis is not very explicit. The mainstream research suggested that dysfunction of upper airway dilator muscles is one of the hazard factors. Genioglossus innervated by the hypoglossal nerve plays crucial roles. It could expand volume of pharyngeal cavity, and increase airflow rate when stimulate it.With the development of anatomy and physiology, hypoglossal nerve stimulation(HGNS) entered into clinical trials, and had made tremendous progress since 2001. Most of clinical trials show that, it could dramatically improve the smooth general peculiarity of the upper respiratory tract in patients with OSAHS in the sleeping state.
ABSTRACT
The prevalence of obstructive sleep apnea (OSA) is estimated to be 1–5% of the adult population world-wide, and in Korea, it is reported at 4.5% of men and 3.2% of women (Age 40 to 69 years old). Active treatment of OSA is associated with decrease in insulin resistance, cardiovascular disease, psychosocial problems, and mortality. Surgical treatment of OSA has evolved in the era of neuromodulation with the advent of hypoglossal nerve stimulation (HGNS). We share this review of HGNS with our maxillofacial surgical colleagues to expand the scope of surgical care for OSA.

Hypoglossal nerve palsy is a rare complication of endotracheal intubation. The mechanism of nerve palsy is mainly attributed to stretching or compression of the nerve during airway manipulation. The cuff pressure can also contribute to the occurrence of hypoglossal nerve palsy. Since it is often accompanied by other cranial nerve palsies, meticulous overall cranial nerve examination is necessary. The main treatment is supportive with respiratory monitoring. The prognosis is favorable. Majority of patients achieve nearly full recovery of nerve function. Here, we report a case of unilateral hypoglossal nerve palsy following usual, uneventful endotracheal intubation and review the literature.

Abstract Introduction: There is no technique of facial nerve reconstruction that guarantees facial function recovery up to grade III. Objective: To evaluate the efficacy and safety of different facial nerve reconstruction techniques. Methods: Facial nerve reconstruction was performed in 22 patients (facial nerve interpositional graft in 11 patients and hypoglossal-facial nerve transfer in another 11 patients). All patients had facial function House-Brackmann (HB) grade VI, either caused by trauma or after resection of a tumor. All patients were submitted to a primary nerve reconstruction except 7 patients, where late reconstruction was performed two weeks to four months after the initial surgery. The follow-up period was at least two years. Results: For facial nerve interpositional graft technique, we achieved facial function HB grade III in eight patients and grade IV in three patients. Synkinesis was found in eight patients, and facial contracture with synkinesis was found in two patients. In regards to hypoglossal-facial nerve transfer using different modifications, we achieved facial function HB grade III in nine patients and grade IV in two patients. Facial contracture, synkinesis and tongue atrophy were found in three patients, and synkinesis was found in five patients. However, those who had primary direct facial-hypoglossal end-to-side anastomosis showed the best result without any neurological deficit. Conclusion: Among various reanimation techniques, when indicated, direct end-to-side facial-hypoglossal anastomosis through epineural suturing is the most effective technique with excellent outcomes for facial reanimation and preservation of tongue movement, particularly when performed as a primary technique.
Resumo Introdução: Não existe uma técnica de reconstrução do nervo facial que garanta a recuperação da função facial até o grau III. Objetivo: Avaliar a eficácia e segurança de diferentes técnicas de reconstrução do nervo facial. Método: Ao todo, 22 pacientes foram submetidos a reconstrução do nervo facial (enxerto com interposição do nervo facial em 11 pacientes e com transferência do nervo hipoglosso facial em 11 pacientes). Todos os pacientes apresentavam função facial de grau VI (de acordo com a classificação de House-Brackmann - HB) causada por trauma ou pela ressecção de um tumor. A reconstrução do nervo principal foi efetuada, exceto em sete pacientes, nos quais a reconstrução foi realizada entre duas semanas a quatro meses após a cirurgia inicial. O período de acompanhamento foi de, no mínimo, dois anos. Resultados: Para a técnica de enxerto com interposição de nervo facial, o grau de função facial obtido foi HB III em oito pacientes e HB IV em três pacientes. Sincinesia foi observada em oito pacientes e contratura facial com sincinesia em dois pacientes. Em relação à transferência do nervo hipoglosso facial com o uso de diferentes modificações, obtivemos função facial HB grau III em nove pacientes e HB grau IV em dois pacientes. Contratura facial, sincinesia e atrofia lingual foram observadas em três pacientes e sincinesia observada em cinco pacientes. No entanto, aqueles submetidos a anastomose primária direta hipoglosso-facial término-lateral apresentaram o melhor resultado, sem qualquer déficit neurológico. Conclusão: Entre as várias técnicas de reanimação, sempre que possível, a anastomose direta término-lateral hopoglosso-facial por meio de sutura epineural é a técnica mais eficaz, com excelentes resultados para reanimação facial e preservação do movimento da língua, especialmente quando realizada como técnica primária.
