Endoscopic transoral approach nasopharyngectomy for petroclival and jugular foramen nasopharyngeal carcinoma / 中华耳鼻咽喉头颈外科杂志

Objective: To describe a technique of endoscopic transoral approach nasopharyngectomy for petroclival and jugular foramen nasopharyngeal carcinoma, based on anatomic studies and surgeries. Methods: Three dry human skulls and five fresh human cadaver heads were used for anatomic study of a endoscopic transoral approach to expose petroclival and jugular foramen. The anatomical landmarks and the extent of exposure were recorded. Six clinical cases who were treated in Eye & ENT Hospital, Fudan University from June 2020 to April 2022 were used to illustrate the technique and feasibility of this approach and to assess its indications and advantages, including 3 males and 3 females, aged 42 to 69 years old. Descriptive analysis was used in this research. Results: On the basis of the preservation of the internal pterygoid muscle and the external pterygoid muscle, this approach could fully expose the parapharyngeal, petrosal and paraclival segment internal carotid arteries, and safely deal with the lesions of jugular foramen and petroclival region. The 6 patients in our study tolerated the procedure well. Postoperative enhanced MRI showed complete resection of the tumor and no postoperative masticatory dysfunction. Conclusion: Endoscopic transoral approach is a safe, minimally invasive and effective surgical treatment for petroclival and jugular foramen recurrent nasopharyngeal carcinoma.

Abstract Introduction: The juvenile nasopharyngeal angiofibroma (ANJ) is a benign, infrequent and highly vascularized tumor. It is locally aggressive, found almost only in adolescent male patients. The classical clinical presentation is recurrent epistaxis and nasal obstruction. Aim: To review the experience of exclusive endoscopic surgery for patients with ANJ by the rhinology team of Hospital del Salvador. Material and Method: Retrospective, cross sectional, descriptive study with research of medical records of patients with exclusive endoscopic surgery treatment between January 2011 and June 2017. Results: 16 patients with a mean age of 17.2 years, 81% had nasal obstruction and epistaxis. All of them were embolized 48 to 24 hours prior surgery. Mean surgical time was 199 minutes. Estimated bleeding was 831 ml among all patients, with only one requiring blood transfusions, while 71% did not need nasal packing. Average length of hospital stay was 4.6 days. Only one patient had a recurrence after one year of surgery. Conclusion: Results of patients with ANJ treated in Hospital del Salvador reassert the success of the exclusive endoscopic surgery versus traditional open approaches, showing better results.

Retropharyngeal lymph node dissection in head and neck cancers treated with transoral robotic surgery / 中华肿瘤杂志

Objective: To evaluate the indications, safety, feasibility, and surgical technique for patients with head and neck cancers undergoing transoral robotic retropharyngeal lymph node (RPLN) dissection. Methods: The current study enrolled 12 consecutive head and neck cancer patients (seven males and four females) who underwent transoral robotic RPLN dissection with the da Vinci surgical robotic system at the Sun Yat-sen University Cancer Center from May 2019 to July 2020. Seven patients were diagnosed as nasopharyngeal carcinoma with RPLN metastasis after initial treatments, 4 patients were diagnosed as thyroid carcinoma with RPLN metastasis after initial treatments, and one patient was diagnosed as oropharyngeal carcinoma with RPLN metastasis before initial treatments. The operation procedure and duration time, intraoperative blood loss volume and complications, nasogastric feeding tube dependence, tracheostomy dependence, postoperative complications, and hospitalization time were recorded and analyzed. Results: All patients were successfully treated by transoral robotic dissection of the metastatic RPLNs, none of which was converted to open surgery. RPLNs were completely resected in 10 patients, and partly resected in 2 patients (both were nasopharyngeal carcinoma patients). The mean number of RPLN dissected was 1.7. The operation duration time and intraoperative blood loss volume were (191.3±101.1) min and (150.0±86.6) ml, respectively. There was no severe intraoperative complication such as massive haemorrhage or adjacent organ injury during surgery. Nasogastric tube use was required in all patients with (17.1±10.6) days of dependence, while tracheotomy was performed in 8 patients with (11.6±10.7) days of dependence. The postoperative hospitalization stay was (8.5±5.7) days. Postoperative complications occurred in 4 patients, including 2 of retropharyngeal incision and 2 of dysphagia. During a follow-up of (6.5±5.1) months, disease-free progression was observed in all patients, 10 patients were disease-free survival and other 2 patients were survival with tumor burden. Conclusions: The transoral robotic RPLN dissection is safety and feasible. Compared with the traditional open surgical approach, it is less traumatic and safer, has fewer complications and good clinical application potentiality. The indications for transoral robotic RPLN dissection include thyroid carcinoma, oropharyngeal carcinoma, and some selected nasopharyngeal carcinoma and other head and neck cancers. Metastatic RPLNs from some nasopharyngeal carcinoma with incomplete capsule, unclear border and adhesion to the surrounding vessels are not suitable for transoral robotic RPLN dissection.

Clinical study on endoscopic surgery for soft tissue necrosis of cranial base after radiotherapy for nasopharyngeal carcinoma / 中华耳鼻咽喉头颈外科杂志

Objective: To investigate the diagnosis and surgical treatment of patients with soft tissue necrosis of cranial base after radiotherapy for nasopharyngeal carcinoma (NPC). Methods: The clinical data of 7 NPC patients with soft tissue necrosis but not bone necrosis after radiotherapy were retrospectively analyzed.They were treated in Xiangya Hospital from 2015 to 2019. The clinical manifestations, diagnosis, treatment and prognosis were analyzed. The major clinical symptoms of the 7 patients were headache in 7 cases, hearing loss in 7 cases, long-term nasal malodor in 5 cases and epistaxis in 2 cases. All patients underwent high-resolution CT, MR and magnetic resonance angiography (MRA) before operation. All cases were treated with extended transnasal endoscopic approach under general anesthesia for resection of necrotic tissue. Five cases had their affected cartilaginous segments of the eustachian tubes partially or completely resected, 7 cases were treated with myringotomy and tube insertion, and 1 case was treated with pansinusectomy. Anti-inflammatory treatment were carried out during the perioperative period. The recovery of patients was observed and recorded through regular follow-up (from 6 months to 3 years) after the operation. Results: Nasopharynx soft tissue lesions can be seen in seven patients with bone cortex integrity by CT, and small bubble shadow can be seen at junction area between skull base soft tissue lesions and skull base bone surface.MR and MRA examination showed extensive inflammatory changes of nasopharynx. Parapharyngeal irregular necrotic cavity was found in 6 cases without central enhancement, demonstrating edema of surrounding soft tissue. The necrotic tissue of all 7 patients was surgically removed. Postoperative pathological examinations confirmed that all of them were necrotic soft and cartilaginous tissue, without tumor recurrence. The symptoms of all patients were significantly alleviated after operation. Headache was cured in 5 cases and relieved in 2 cases. Nasal malodor was cured in 4 cases and alleviated in 1 case. During the follow-up period, 5 patients survived, and 2 patients who had their eustachian tube reserved died. One of them died of nasopharyngeal hemorrhage caused by recurrent nasopharyngeal necrosis 3 months after the operation. Another case died of severe intracranial infection 6 months after operation. Conclusions: The diagnosis of skull base soft tissue necrosis after radiotherapy for nasopharyngeal carcinoma needs comprehensive analysis of radiotherapy history, clinical manifestations and imaging examination. High resolution CT, MR and MRA of skull base are very important for diagnosis. Early active removal of large-scale necrotic lesions under endoscope and partial or total resection of eustachian tube cartilage according to the involvement of eustachian tube cartilage is effective means of controling skull base soft tissue necrosis after radiotherapy. The effective means of necrosis can improve the quality of life of patients.

Plasmocitoma extramedular de laringe: a propósito de un caso / Extramedullary plasmacytoma of the larynx: a case report

Resumen Los plasmocitomas solitarios son una rara forma de presentación de neoplasias de células plasmáticas. Deben ser diferenciados del mieloma múltiple en el momento del diagnóstico y realizar un seguimiento estricto por el riesgo de transformación a mieloma. La localización de los mismos en la laringe es muy inusual, dado que sólo se han publicado 56 casos. Se presenta el caso de una paciente con un plasmocitoma extramedular de laringe que se trató mediante cirugía y radioterapia. Se revisan los criterios diagnósticos y los problemas terapéuticos.

Abstract Solitary plasmacytomas are a rare form of plasma cell neoplasms. They should be differentiated from multiple myeloma at the time of diagnosis and strictly monitored for the risk of transformation to myeloma. Their location in the larynx is very unusual, since only 56 cases have been published. We present the case of a patient with extramedullary plasmacytoma of the larynx that has been treated with surgery and radiotherapy. We reviewed the literature for diagnostic criteria and therapeutic problems.

Introducción: El fibroangioma nasofaríngeo juvenil es un tumor vascular benigno localmente agresivo, que afecta casi exclusivamente la nasofaringe de adolescentes de sexo masculino. Su manejo es complejo dada su extensión, naturaleza vascular y sus frecuentes recurrencias. Objetivo: Mostrar la experiencia de 15 años en fibroangioma juvenil en nuestro centro. Material y método: Estudio descriptivo retrospectivo de los pacientes con diagnóstico de ingreso de fibroangioma nasofaríngeo juvenil al Servicio de Otorrinolaringología del Hospital Barros Luco Trudeau entre los años 1997 y 2011, caracterizando al grupo de estudio en cuanto a características clínico-demográficas, vasos aferentes, relación entre etapa tumoral y vascularización, manejo terapéutico, complicaciones y recurrencias. Resultados: Se obtuvo un total de 20 pacientes, todos de sexo masculino, con un promedio de edad de 13,9 años. El síntoma de presentación más frecuente fue la epistaxis a repetición y obstrucción nasal presente en el 90% y 80%, respectivamente. Todos los pacientes se estudiaron con tomografia computarizada y recibieron embolización arterial preoperatoria. La mayoría de los tumores fueron de tipo II (65%) y III (20%), según clasificación de Radkowski. La técnica quirúrgica más empleada fue abierta (57,8%). Radioterapia en un caso. El vaso aferente principal fue la maxilar interno ipsilateral en el 100%. Todos los fibroangiomas etapa III eran además irrigados por la arteria carótida interna. Se encontró 20% de persistencia y 15% de recidiva. Conclusión: Nuestros resultados concuerdan con la gran mayoría de las series publicadas en la literatura. Epistaxis recurrente, obstrucción nasal y tumor nasal unilateral deben hacernos sospechar de esta patología en un adolescente masculino. El tratamiento de elección es la cirugía con embolización preoperatoria. La vía de abordaje endoscópica presenta menor morbilidad posoperatoria en pacientes con estadios I y II de Radkowski. Todos los fibroangiomas con compromiso intracraneano, presentan irrigación también del sistema carotideo interno.

Introduction: Nasopharyngeal Fibroangioma is a locally aggressive benign vascular tumor. Its management is complex given its size, vascular nature and its frequent recurrences. Aim: To show the experience of 15 years in Juvenile Fibroangioma in our center. Material and method: Retrospective descriptive study of patients admitted with a diagnosis of Juvenile Fibroangioma Nasopharyngeal in the Department of Otolaryngology Hospital Barros Luco Trudeau between 1997 and 2011. Results: A total of 20 patients was obtained. The most common presenting symptom was recurrent epistaxis and nasal obstruction present in 90% and 80% respectively. The most common surgical technique was open (57.8%). Radiotherapy in one case. The main afferent vessel was the ipsilateral internal maxillary in 100%. All Fibroangioma stage III were also supplied by the internal carotid artery. 20% of persistence and 15% of recurrence was found. Conclusion: Recurrent epistaxis, nasal obstruction and unilateral nasal tumor should raise the suspicion of this disease in a male teenager. The treatment of choice is surgery with preoperative embolization. The route of endoscopic approach has less postoperative morbidity in patients with stage I and II of Radkowski. All Fibroangioma with intracranial commitment, have also the internal carotid irrigation system.

Endoscopic endonasal approach for mass resection of the pterygopalatine fossa

OBJECTIVES: Access to the pterygopalatine fossa is very difficult due to its complex anatomy. Therefore, an open approach is traditionally used, but morbidity is unavoidable. To overcome this problem, an endoscopic endonasal approach was developed as a minimally invasive procedure. The surgical aim of the present study was to evaluate the utility of the endoscopic endonasal approach for the management of both benign and malignant tumors of the pterygopalatine fossa. METHOD: We report our experience with the endoscopic endonasal approach for the management of both benign and malignant tumors and summarize recent recommendations. A total of 13 patients underwent surgery via the endoscopic endonasal approach for pterygopalatine fossa masses from 2014 to 2016. This case group consisted of 12 benign tumors (10 juvenile nasopharyngeal angiofibromas and two schwannomas) and one malignant tumor. RESULTS: No recurrent tumor developed during the follow-up period. One residual tumor (juvenile nasopharyngeal angiofibroma) that remained in the cavernous sinus was stable. There were no significant complications. Typical sequelae included hypesthesia of the maxillary nerve, trismus, and dry eye syndrome. CONCLUSION: The low frequency of complications together with the high efficacy of resection support the use of the endoscopic endonasal approach as a feasible, safe, and beneficial technique for the management of masses in the pterygopalatine fossa.

Este tiene como ventajas menores pérdidas sanguíneas intraoperatorias, una disminución del número días de hospitalización y las tasas de recurrencia.

Introduction: Juvenile nasopharyngeal angiofibroma is a benign vascular neoplasm, locally aggressive that develops almost exclusively in adolescent males. Its usual clinical manifestations are epistaxis and nasal obstruction. Aim: To show the experience in the Department of Otolaryngology Hospital Carlos van Buren of angiofibromas operated by endoscopic and open surgery between the years 2008 and 2015, and review of the literature. Material and Method: Retrospective descriptive study of patients diagnosed with juvenile nasopharyngeal angiofibroma admitted in the Department of Otolaryngology Hospital Carlos van Buren, Valparaiso between 2008 and 2015. Results: A total of 6 cases were identified. The age of patients ranged from 12 to 29 years. The most common presenting symptoms were recurrent epistaxis and nasal obstruction, both present in 5/6 of patients. All the cases were studied with CT, MRI and angiography. All cases had pre-surgical endovascular embolisation48 hours prior to excision. Conclusions: The results correlate with those seen in the literature. The endoscopic approach is the better option, because of its lower intraoperative blood loss, days of hospitalization and recurrence.

Complicações no tratamento do nasoangiofibroma juvenil com invasão intracraniana / Complications in the endoscopic and endoscopic-assisted treatment of juvenile nasopharyngeal angiofibroma with intracranial extension

Introdução: Apesar de ser uma neoplasia rara, o nasoangiofibroma juvenil (NAJ) está associado a elevadas taxas de morbimortalidade e potencial invasão intracraniana. Excisão cirúrgica é o tratamento de escolha. O acesso endoscópico transnasal tem substituído a abordagem cirúrgica externa nas lesões pequenas, podendo ser utilizados de forma conjunta nos casos mais avançados. Objetivo: Deteminar a prevalência de complicações no tratamento cirúrgico endoscópico ou guiado por endoscopia nos NAJ com mínima invasão intracraniana. Método: Trata-se de um estudo retrospectivo realizado nos pacientes com NAJ classe IIIA de Radkowski, com mínima invasão intracraniana, submetidos à cirurgia endoscópica guiada por endoscopia ou acesso cirúrgico externo, entre janeiro de 1996 e maio de 2010. Resultados: No total, 13 pacientes foram submetidos a tratamento cirúrgico. O acesso endoscópico exclusivo foi realizado em três pacientes, sem complicações pós-operatórias. Cirurgia guiada por endoscopia foi realizada em três pacientes, com duas complicações pós-operatórias. Acesso cirúrgico externo foi realizado em sete pacientes. Conclusão: O tratamento cirúrgico do nasoangiofibroma com invasão intracraniana constitui um grande desafio a otorrinolaringologistas e neurocirurgiões. Neste aspecto, os índices de sucesso associado à baixa taxa de complicação intra e pós-operatória parecem ser indicativos de que o acesso endoscópico vem ganhando espaço no manejo do NAJ IIIA da classificação de Radkowski. .

Introduction: Although it is a rare neoplasm, juvenile nasopharyngeal angiofibroma (JNA) is associated with high rates of morbidity and mortality, with the potential for intracranial extension. Surgical excision is the main treatment. The external approach has largely been replaced by the endoscopic approach in small lesions, and it can be used as a complement in more advanced cases. However, there is no consensus in the literature regarding the complications of surgical treatment of JNAs with intracranial extension. Aim: To assess the prevalence of complications in endoscopic or endoscopic-assisted surgical treatment of JNA with minimal intracranial invasion. Methods: This was a retrospective cohort study of all patients with JNA with intracranial extension (Radkowski grade IIIa) treated with endoscopic, endoscopic-assisted, and external surgery from January of 1996 to May of 2010. Results: Thirteen patients underwent surgery. Endoscopic surgery was performed in three patients, without postoperative complications; endoscopic-assisted surgery in three others, with two instances of complications, and external surgery in seven. Conclusions: Operative treatment of nasopharyngeal angiofibroma with intracranial extension is one of the major challenges of ENT and neurosurgical practice. The success rates and low intra- and postoperative complication rates of endoscopic surgery suggest that this route has been gaining ground in the management of Radkowski grade IIIa JNAs. .

Comparação entre cirurgia endoscópica e aberta em 37 pacientes com nasoangiofibroma / Comparison between endoscopic and open surgery in 37 patients with nasopharyngeal angiofibroma

O nasoangiofibroma é um tumor vascular benigno raro da nasofaringe, 0,5 por cento de todas as neoplasias da cabeça e pescoço. Embora o tratamento de escolha seja a cirurgia, não há consenso sobre qual a melhor abordagem. OBJETIVOS: Comparar o tempo cirúrgico e a necessidade de transfusão intraoperatória em pacientes submetidos à cirurgia endoscópica versus aberta/combinada e relacionar a necessidade de transfusão intra-operatória com o tempo entre embolização e cirurgia. MATERIAL E MÉTODO: Estudo descritivo, analítico, retrospectivo, com abordagem quantitativa desenvolvido no serviço de otorrinolaringologia de um hospital-escola. Analisados 37 pacientes com nasoangiofibroma submetidos ao tratamento cirúrgico. Dados obtidos de prontuários. Analisados com os testes de Fisher-Freeman-Halton e de Games-Howell. Considerou-se significante se p < 0,05. Desenho do estudo: Estudo de coorte histórica com corte transversal. RESULTADOS: A abordagem endoscópica teve um menor tempo (p <0,0001).Houve uma menor necessidade de transfusão intraoperatória quando a embolização foi realizada no quarto dia. CONCLUSÃO: Sugere-se que o período citado seria o ideal para a realização da embolização e que a cirurgia endoscópica por demandar menos tempo estaria associada a uma menor morbidade. Entretanto, não se conseguiu demonstrar qual grupo de pacientes de acordo com o estádio tumoral se beneficiaria com determinada técnica.

Juvenile nasopharyngeal angiofibroma is a rare benign vascular tumor of the nasopharynx. Although the treatment of choice is surgery, there is no consensus on what is the best approach. AIM: To compare surgical time and intraoperative transfusion requirements in patients undergoing endoscopic surgery versus open / combined and relate the need for transfusion during surgery with the time between embolization and surgery. MATERIAL AND METHODS: Study descriptive, analytical, retrospective study with a quantitative approach developed in the Otorhinolaryngology department of a teaching hospital. Analyzed 37 patients with angiofibroma undergoing surgical treatment. Data obtained from medical records. Analyzed with tests of the Fisher-Freeman-Halton and Games-Howell. Was considered significant if p <0.05. Study design: Historical cohort study with cross-sectional. RESULTS: The endoscopic approach had a shorter operative time (p <0.0001). There is less need for transfusion during surgery when the embolization was performed on the fourth day. CONCLUSION: This suggests that the period ahead would be ideal to perform the process of embolization and endoscopic surgery by demanding less time would be associated with a lower morbidity. This study, however, failed to show which group of patients according to tumor stage would benefit from specific technical.

A case of central retinal artery occlusion following embolization procedure for juvenile nasopharyngeal angiofibroma.

A 23-year-old male patient with right nasal Juvenile Nasopharyngeal Angiofibroma (JNA) developed Central Retinal Artery Occlusion (CRAO) during embolization of the tumor using polyvinyl alcohol particles before endoscopic excision. Classic CRAO management was initiated by an ophthalmologist after 12 h. Retrospective evaluation of the angiograms revealed a tiny communication between the external carotid and ophthalmic arteries which had not been noticed before embolization. During endoscopic excision, the tumor was found to originate extraordinarily from midline structures. It was concluded that CRAO might be a rare complication of JNA embolization. Careful preoperative angiographic evaluations to detect communicating arteries and immediate ophthalmologic consultation in case of developing visual symptoms during the procedure are necessary.

Experiência de sete anos em pacientes com angiofibroma nasofaríngeo juvenil / A seven-year experience with patients with juvenile nasopharyngeal angiofibroma

O angiofibroma nasofaríngeo juvenil (ANJ) é um raro tumor em adolescentes masculinos originário na nasofaringe. OBJETIVOS: Apresentar a experiência do tratamento do ANJ em pacientes do Serviço de Otorrinolaringologia entre 2001 e 2008. MATERIAL E MÉTODOS: Foram revisados de prontuários do Serviço de Otorrinolaringologia os dados demográficos, apresentação clínica, métodos de investigação e tratamento de 16 pacientes. DESENHO DO ESTUDO: estudo descritivo, retrospectivo, de corte transversal. Resultados: Todos os pacientes são do gênero masculino e a média de idade ao diagnóstico foi de 16,8 anos (variação de 9 a 23 anos), sendo mais de 56 por cento deles com estádio II de Fisch. Embolização pré-operatória foi realizada em 10 pacientes (62,5 por cento). Todos os 16 pacientes foram submetidos à ressecção cirúrgica. Dois pacientes (66,7 por cento) que não foram submetidos à embolização pré-operatória necessitaram de transfusão sanguínea. O índice de recidiva foi de 43,75 por cento e o índice de cura foi 93,75 por cento. CONCLUSÕES: Embolização pré-operatória diminui a perda sanguínea intra-operatória. O índice de recidiva foi relacionado ao estadiamento avançado do tumor ao diagnóstico e à não-realização de embolização pré-operatória. Cirurgia associada à embolização pré-operatória são os principais tratamentos do ANJ. Todos os pacientes devem ter estudos de imagem pré-operatórios, especialmente tomografia computadorizada, para auxiliar no planejamento cirúrgico e no seguimento.

Juvenile nasopharyngeal angiofibroma (JNA) is a rare tumor in adolescent males. It originates in the nasopharynx. AIM: to present the experience of JNA management at an Otorhinolaryngology Service between 2001 and 2008. MATERIALS AND METHODS: Demographical data, clinical presentation, investigations as well as the treatment of sixteen JNA patients were reviewed and collected from medical records from the ORL Service. DESIGN: Cross-sectional, retrospective and descriptive study. Results: All JNA patients were male. The average age at diagnosis was 16.8 years (range 9-23 years). More than 56 percent of the patients were classified as Fisch II. Preoperative embolization was carried out in ten (62.5 percent) patients. All 16 patients were submitted to primary surgical resection. Two patients (66.7 percent) who didn't receive preoperative embolization required intraoperative blood transfusion. The overall recurrence rate was 43.75 percent and the cure rate was 93.75 percent. CONCLUSION: Preoperative embolization minimizes intraoperative blood loss. The recurrence rate was related to advanced tumoral stage at diagnostic and the lack of preoperative embolization. Surgery combined with preoperative embolization is the major treatment for JNA. All the patients should undergo preoperative imaging studies, especially CT, to assist in surgical planning and follow-up.

Fibroangioma nasofaríngeo juvenil: experiencia de 12 años en el Hospital Clínico de la Universidad de Chile / Juvenile nasopharyngeal angiofibroma: 12 years experience at the University of Chile Clinical Hospital

Introducción: El fibroangioma juvenil es un tumor vascular que afecta casi exclusivamente la nasofaringe de adolescentes de sexo masculino. Su manejo es complejo dada su naturaleza vascular y sus frecuentes recurrencias. Objetivo: Mostrar la experiencia de 12 años en fibroangioma juvenil Material y método: Estudio descriptivo retrospectivo de los pacientes que ingresaron con diagnóstico de fibroangioma nasofaríngeo juvenil al Servicio de Otorrinolaringología del Hospital Clínico de la Universidad de Chile entre los años 1996 y 2008, caracterizando al grupo de estudio en cuanto a clínica, diagnóstico, manejo terapéutico, complicaciones y recurrencias. Resultados: Se obtuvo un total de 22 pacientes, todos de sexo masculino, con un promedio de edad de 17,7 años. El síntoma de presentación más frecuente fue la epistaxis a repetición presente en el 81,8 por ciento de los casos. Todos los pacientes se estudiaron con tomografia computarizada y recibieron embolización arterial preoperatoria. La mayoría de los tumores fueron de tipo IIByllC (68,1 por ciento) según Radkowski y la técnica quirúrgica más empleada fue la endoscópica (54,5 por ciento). Hubo sólo una complicación mayor, pero derivada del procedimiento de embolización y no de la cirugía propiamente tal. Se encontró 22,7 por ciento de recurrencias (n =5, todas endoscópicas), con un tiempo libre de enfermedad de 8,2 meses promedio. Discusión y conclusión: Nuestros resultados concuerdan con la gran mayoría de las series publicadas en la literatura. La decisión terapéutica se basa en la determinación del tamaño tumoral y su extensión, prefiriendo inicialmente un abordaje endoscópico por su carácter poco invasivo y por presentar menor sangrado, tiempo quirúrgico y estadía hospitalaria; siempre que el estadio tumoral lo permita. La embolización arterial, independiente de la vía de abordaje, debe ser de rutina.

Introduction: Juvenile nasopharyngeal angiofibroma is a vascular tumor that occurs almost exclusively in the nasopharynx of adolescent males. Its management is complex because of its vascular nature and frequent recurrence. Aim: To review the experience of 12 years in juvenile nasopharyngeal angiofibroma. Material and method: Retrospective study of patients admitted with diagnosis of juvenile nasopharyngeal angiofibroma at the Otorhinolaryngology Department, University of Chile Clinical Hospital, between 1996 and 2008, characterizing the study group in terms of clinical features, diagnosis, treatment, complications and recurrences. Results: We obtained 22 patients, all male, with an average age of 17.7 years. The most common presenting symptom was recurrent epitasis, present in up to 81.8 percent of cases. All patients were studied with computed tomography and received preoperative arterial embolization. Most tumors were type IIB and C (68.1 percent) and the endoscopic surgical technique was predominant. There was only one major complication, but derived from the embolization procedure and not the surgery itself. There was a 22.7 percent recurrence, with disease-free time of 8.2 months on average. Discussion and Conclusion: Our results agree with most of the series published in the literature. The therapeutic decision is based on the determination of tumor size and extension, preferring an initial endoscopic approach, for its minimally invasive nature and because they present less bleeding, surgical time and hospital stay if the tumor stage allows. Arterial embolization, regardless of the surgical approach, should be routine.

Transpalatal approach- a cosmetically acceptable route for removal of small juvenile nasopharyngeal angiofibroma

To determine frequency of employment of transpalatal route for a cosmetically acceptable outcome in surgically addressing small juvenile nasopharyngeal angiofibroma. Descriptive Study. The study was carried out in department of ENT and Head and Neck surgery Combined Military Hospital Rawalpindi and Combined Military Hospital Lahore from January 2005 - January 2008. Patients age less than 18 years with small juvenile nasopharyngeal angiofibroma [Radkowskis Stage I] were included in the study. These patients were managed surgically. A total of twenty four cases were included in this study, nine [37.5%] were managed by transpalatal route. Four patients had stage la and five had Stage Ib disease. Patients were studied in terms of facial appearance six months post operatively. None of the patients showed any facial deformity. Transpalatal route is novel approach to deal cosmetically with small juvenile nasopharyngeal angiofibroma

Nasoangiofibroma juvenil: nuestra experiencia en los últimos 10 años y revisión de la literatura / Juvenile nasopharyngeal angiofibroma: our experience in the last 10 years and review of the literature

Introducción: El nasoangiofibroma juvenil es un tumor benigno con comportamiento de agresividad local, dadas las importantes epistaxis que provoca, la frecuente recidiva local y la complejidad terapéutica que se presenta ante esta patología; se presenta exclusivamente en hombres adolescentes y corresponde al 0,5 por ciento-0,05 por ciento de todos los tumores de cabeza y cuello. Objetivo: Determinar el manejo y las características del paciente con el diagnóstico de nasoagiofibroma juvenil que acude a nuestro servicio. Evaluar necesidad de transfusión sanguínea. Exponer las complicaciones encontradas. Material y método: Se realizó un trabajo retrospectivo observacional de corte transversal de pacientes con diagnóstico de nasoangiofibroma juvenil (NAJ), confirmado por estudios histológicos en la Cátedra de Otorrinolaringología de la Facultad de Ciencias Médicas de la Universidad Nacional de Asunción, desde enero de 1998 hasta septiembre de 2008. Resultados: Con un total de 45, de los cuales 44 recibieron tratamiento quirúrgico. El rango de edad estaba comprendido entre 7 a 34 años, con una mediana de 16 años y un promedio de 17 años, todos de sexo masculino. Se presentaron con mayor frecuencia en estadio Fisch II, rango de evolución sintomática de 1 a 60 meses, con una mediana de 7 meses de evolución de epistaxis recurrente, obstrucción nasal y rinorrea. La mayoría de grupo sanguíneo O Rh+, provenientes del Departamento Central, recibiendo como tratamiento la resección endoscópica. Siete pacientes presentaron recidivas, con una mediana de 7 meses desde el tratamiento. En 58,8 por ciento de los procedimientos quirúrgicos fue necesaria la transfusión de derivados sanguíneos. Conclusión: Los pacientes que acuden al servicio con el diagnóstico de nasoangiofibroma juvenil, son sometidos a tratamiento quirúrgico en la totalidad de los casos. En la mayoría de los casos se requirió algún tipo de transfusión sanguínea. No hubo complicaciones por...

Introduction: The juvenile Nasopharyngeal Angiofibroma is a benign tumor with behavior of local aggressiveness, given the important epistaxis that it provokes, the frequent local recidiva and the therapeutic complexity that one presents before this pathology; he appears exclusively in teen men and corresponds to 0,5 percent-0,05 percent of all the tumors of head and neck. Aim: To determine the managing and the characteristics of the patient with juvenile Nasopharyngeal Angiofibroma diagnosis that comes to our service. To evaluate need of blood transfusion. To expose the opposing complications. Material and method: There realized a retrospective work observacional of patients' transverse court (cut) with diagnosis of juvenile Nasopharyngeal Angiofibroma (NAJ), confirmed by histological studies in the Service of Otolaryngology of the Asuncion's National University, from January, 1998 until September, 2008. Results: With a whole of 45, of which 44 received surgical treatment. The range of age was understood (included) between (among) 7 to 34 years, with a median of 16 years and an average of 17 years, all of masculine sex. Appellants presented with major frequency in estadio Fisch II, range of symptomatic evolution from 1 to 60 months, with a median of 7 months of evolution of epistaxis, nasal obstruction and rinorrea. The majority of blood group O Rh +, from the Central department, receiving as treatment the resection endoscopic. 7 patients presented recidivas, with a median of 7 months from the treatment. In 58,8 percent of the surgical procedures there was necessary the transfusion of blood derivatives. Conclusion: The patients who come to the service with juvenile nasopharyngeal angiofibroma diagnosis, are submitted to surgical treatment in the totality of the cases. In most cases there was needed some type of blood transfusion. There were no complications for the surgical procedure.

Adenoma ectópico hipofisiario: reporte de un caso y revisión de la literatura: [revisión] / Ectopic hypophysial adenoma: case report and literature review: [revision]

Los adenomas son los tumores hipofisiarios más frecuentes y ocasionalmente se pueden ubicar fuera de la silla turca, ya sea por extensión desde ésta o más rara vez por ubicación ectópica. Se presenta el caso de una paciente de 56 años, en la que en un TAC de cerebro solicitado en el contexto de un síndrome vertiginoso, se encuentra una lesión en región esfenoidal que se extiende al clivus, frente a la cual se plantean como posibilidades diagnósticas: cordoma, carcinoma nasofaríngeo, tumor derivado de una glándula salival menor y un tumor metastático. La lesión es abordada y extraída endoscópicamente, comprobándose finalmente que correspondía a un adenoma ectópico hipofisiario.

Adenomas are the most frequent hypophyseal tumors, and they can be occasionally located outside the sella turcica, either by growth from it or, less frequently by ectopic location. The case of a 56year old female is presented, in which a brain TC prescribed in the context of a vertiginous syndrome revealed a lesion located in the sphenoid region extending to the clivus. Several diagnoses were discussed: chordoma, nasopharyngeal carcinoma, minor salivary gland derived tumor, and metastatic tumor. The lesión was surgically approached and excised, and it was finally demonstrated to be an ectopic hypophyseal adenoma.
