ABSTRACT

Encephalocele is a protrusion of the central nervous system elements through a defect in the dura mater and in the cranium. The prevalence of encephalocele ranges from 0.08 to 0.5 per 1,000 births. The posterior encephaloceles are more common in North America and Europe, while frontal defect is frequently found in Asia. The present paper describes a 26-year-old male patient presenting with cerebrospinal fluid leak and meningitis symptoms. He was diagnosed with congenital nasoethmoidal encephalocele and treated surgically using a supraorbital approach without complications.

ABSTRACT

The naso-orbito-ethmoidal region is composed of delicate bones and when fractured may result in significant aesthetic-functional impairment. Diagnosis through clinical and imaging findings is extremely important for surgical planning. This study aims to report a case of type III fracture of the naso-orbito-ethmoidal region. Patient D.R.S., female, 13 years old, attended the emergency department of Hospital dos Fornecedores de Cana de Piracicaba (HFCP) - SP with complaint of pain in the fronto-nasal region and respiratory distress after trauma in face of baseball bat. Physical examination showed edema and short blunt injury in the region of the nasal dorsum and frontal region, bilateral periorbital hematoma, hyposphagma in right eye and traumatic telecanthus. When analyzing the computed tomography, it was observed fracture of the nasal bones, also affecting the medial wall of the orbit. The procedure was osteosynthesis of the fractures and reconstruction of the nasal dorsum. The fracture traces were exposed from coronal access, reduction of fractures and use of calvarial bone graft for nasal dorsum reconstruction. The fracture and the graft were fixed with plates of 1,6mm. Postoperative computed tomography analysis showed good graft positioning, but there was still a slight sinking of the left lateral wall of the nose. In a second moment another surgical intervention was done to reduce this wall and an internal containment device was installed. Currently the patient is in a state of observation and a follow-up period of 665 days. In cases of complex nasoorbito-ethmoidal fractures early diagnosis and treatment is essential to minimize sequelae and provide a better aesthetic and functional result.


La región etmoidal nasoorbital está compuesta de huesos delicados y, cuando se fractura, puede provocar una lesión estética-funcional significativa. El diagnóstico mediante hallazgos clínicos y de imagen es de suma importancia para la planificación quirúrgica. El paciente D.R.S., mujer, 13 años, leucoderma, asistió al servicio de emergencia del Hospital de Proveedores de Caña de Azúcar de Piracicaba quejándose de dolor en la región frontal-nasal y dificultad para respirar después de un traumatismo en la cara con un palo. El examen físico reveló edema y lesión contundente en el dorso nasal y la región frontal, hematoma periorbitario bilateral, hiposfagma del ojo derecho y telecanto traumático. Al analizar la tomografía computarizada se observó fractura de los huesosnasales en libro abierto, afectando también la pared medial de la órbita. El enfoque aplicado fue la osteosíntesis de fracturas y la reconstrucción del dorso nasal. Los rastros de fractura se expusieron del abordaje coronal, se redujeron las fracturas y se usaron injertos de casquete para reconstruir el dorso nasal. La fractura y el injerto se fijaron con placas de sistema de 1,6 mm y se realizó la cantopexia de los ligamentos cantales mediales. Se requirió cirugía reparadora secundaria para la corrección de la pared lateral de la nariz, que persistió en el postoperatorio. Actualmente el paciente se encuentra en un estado de conservación y período de seguimiento de 665 días. En casos de fracturas nasoorbitales-etmoidales complejas, el diagnóstico y el tratamiento tempranos son esenciales para minimizar las secuelas y proporcionar un mejor resultado estético y funcional.

ABSTRACT

Abstract Introduction: Radiologic evaluation is mandatory to assess the type of endoscopic approach concerning sinonasal pathology and reconstruction of fractured defects before any treatment modalities are instituted related to medial wall of the orbit. Objective: The goal was to provide improved understanding of the lamina papyracea variations and the relationship with the orbital morphometry. Methods: This retrospective study was performed using computed tomography scans of 200 orbits and results were compared with respect to age, sex, laterality and LP variations. Results: Lamina papyracea variations were categorized as type A, 80.5% (161/200); type B, 16% (32/200); type C, 3.5% (7/200). For medial wall the anterior and posterior lamina papyracea heights and angles were found as 17.14 mm, 147.88º and 9.6 mm, 152.72º, respectively. Also, the length of the lamina papyracea, the mean area of the orbital floor, medial wall, lamina papyracea and orbital entrance were 33.3 mm, 7.2 cm2, 6.89 cm2, 4.51 cm2 and 12.46 cm2 respectively. The orbital height and width were measured as 35.9 mm and 39.2 mm respectively. The mean orbital cavity depth was 46.3 mm from optic foramen to the orbital entrance and the orbital volume was 19.29 cm3. We analyzed the morphometric measurements tending to increase with aging and greater in men and the relationship of them with lamina papyracea types. Conclusion: Precise knowledge of the lamina papyracea anatomy using computed tomography is essential for safer and more effective surgery and preforming the dimensions of an implant. In this way, the postoperative complications can be decreased and the best outcome can be provided.


Resumo Introdução: A avaliação radiológica é mandatória para avaliar o tipo de abordagem endoscópica no tratamento cirúrgico de doença nasossinusal e na reconstrução de fraturas antes de quaisquer modalidades de tratamento relacionadas à parede medial orbital. Objetivo: O objetivo foi proporcionar uma melhor compreensão das variações da lâmina papirácea e a relação com a morfometria orbital. Método: Este estudo retrospectivo foi realizado por meio de tomografia computadorizada de 200 órbitas, e os resultados foram comparados em relação à idade, sexo, lateralidade e variações da lâmina pairácea. Resultados: As variações da lâmina papirácea foram categorizadas como tipo A, 80,5% (161/200); tipo B, 16% (32/200); tipo C, 3,5% (7/200). Para a parede medial, as medidas das alturas anteriores e posteriores da lâmina papirácea e ângulos foram de 17,14 mm, 147,88º e 9,6 mm, 152,72º, respectivamente. Além disso, as medidas do seu comprimento da, da área média do assoalho orbital, e da parede medial, lâmina papyracea e entrada orbital foram: 33,3 mm, 7,2 cm2, 6,89 cm2, 4,51 cm2 e 12,46 cm2, respectivamente. As medidas da altura e da largura orbitais foram 35,9 mm e 39,2 mm, respectivamente. A profundidade média da cavidade orbital foi de 46,3 mm, do forame óptico até a entrada orbital, e o volume orbital foi de 19,29 cm3. Analisamos as medidas morfométricas com tendência a aumentar com o envelhecimento e nos indivíduos do sexo masculino, e a relação das mesmas com os tipos de lâmina. Conclusões: O conhecimento preciso da anatomia da lâmina papirácea por meio de tomografia computadorizada é essencial para uma cirurgia mais segura e eficaz, além de permitir pré-moldar as dimensões do implante. Assim, as complicações pós-operatórias podem ser minimizadas, obtendo-se melhores resultados.

ABSTRACT

The pneumatization area in the crista galli region of the ethmoid bone can be called Sinus Crista Galli (SCG). The authors would like to recommend the terminology as sinus crista galli for pneumatized crista galli. Our aims in this study are to determine SCG on three dimensional Computerized Tomography (CT) images, to investigate its frequency, dimension and to emphasize their clinical significance in children and adults. A total of 360 adult images (160 female, 200 male) and 68(43 female, 25 male) pediatric images were examined. The presence SCG was recorded with axial and coronal paranasal sinus CT images. The height, width, anterposterior diameter of the sinus was measured. All the data we obtained from this study were analyzed using the SPSS 18.0 program. Descriptive statistics are shown as mean ± Sdt. Sinus crista galli was found in 17 examined images of the 360 (4.72 %) in adult group. Chronic pansinusitis was detected in 7 of 17 cases. Frontal sinusitis findings were detected in 7 cases. Sinusitis was not observed in 3 cases. The incidence of SCG was found in 4 pediatric images out of 68 (5.88 %). In 1 out of 4 cases, infection was detected in SCG. We did not observe SCG in the pediatric group with 0-7 years of age. Sinus crista galli was found at low rates in adult and pediatric age group. However; relationship was found between these variation and chronic rhinosinusitis. Additionally, detection of SCG in paranasal sinus CT can be provided better results and reduce complications in anterior cranial fossa surgery.


El área de neumatización en la crista galli del etmoides se puede denominar sinus crista galli (SCG). Los autores recomiendan incluir en la terminología anatómica el término sinus crista galli para la crista galli neumatizada. Los objetivos del estudio fueron determinar la SCG en imágenes tridimensionales de tomografía computarizada (TC), investigar su frecuencia, dimensión y enfatizar su importancia clínica en niños y adultos. Se examinaron un total de 360 imágenes de adultos (160 mujeres, 200 hombres) y 68 (43 mujeres, 25 hombres) en imágenes pediátricas. La presencia de SCG se registró con imágenes de tomografía axial y axial del seno paranasal. Se midió la altura, anchura y diámetro anteroposterior del seno del proceso crista galli. Todos los datos obtenidos se analizaron mediante el programa SPSS 18.0. Las estadísticas descriptivas se muestran como media ± DS. El seno crista galli se encontró en 17/360 (4,72 %) de las imágenes examinadas en el grupo de adultos. Se detectó pansinusitis crónica en 7 de 17 casos. Se detectaron hallazgos de sinusitis frontal en 7 casos. Sinusitis no se observó en 3 casos. La incidencia de SCG se encontró en 4 imágenes pediátricas de 68 (5,88 %). En 1 de cada 4 casos, se detectó infección en SCG. No observamos SCG en el grupo pediátrico con 0-7 años de edad. El seno crista galli se encontró en bajas tasas en adultos y en niños. Sin embargo, se encontró relación entre estas variaciones y la rinosinusitis crónica. Además, la detección de SCG en la tomografía computarizada del seno paranasal puede proporcionar mejores resultados y reducir las complicaciones en la cirugía de la fosa craneal anterior.

ABSTRACT

RESUMEN Introducción: Ramas de la arteria oftálmica contribuyen a la irrigación de diversos territorios de la fosa nasal y de los senos paranasales. Objetivo: El objetivo de nuestro estudio es describir las arterias etmoidales desde su origen intraorbitario, y su relación con las estructuras musculares y nerviosas. Material y Método: Se realizó un estudio anatómico endoscópico en 20 fosas nasales y órbitas de diez cadáveres. Resultados: La disección del plano muscular permitió definir dos espacios de entrada a la órbita. Un primer espacio entre el músculo recto inferior y músculo recto medial (área 1) y otro entre el músculo recto medial y músculo oblicuo superior (área 2). En el área 1, la arteria oftálmica discurrió superior al nervio óptico en el 90%. La arteria etmoidal anterior se observó en todos los casos inferior al músculo oblicuo superior. En el área 2, la arteria etmoidal posterior, se localizó en todos los casos superior al músculo oblicuo superior. No se identificó la arteria etmoidal media en ningún caso. El origen de la arteria supraorbitaria se identificó entre las dos arterias etmoidales. Conclusión: La comprensión anatómica del origen intraorbitario de la arteria oftálmica permite el abordaje de determinada patología intraorbitaria compleja a través de la pared medial de la órbita.


ABSTRACT Introduction: Branches of the ophthalmic artery contribute to the irrigation of various territories of the nasal cavity and paranasal sinuses. Aim: The aim of our study is to describe the intraorbital course of the ethmoidal arteries and their relationship with the muscular and nervous structures. Material and method: We performed twenty nasal cavities and orbital dissections in ten adults cadaveric heads. Results: The dissection of the muscular orbital wall allowed defining two surgical orbital corridors, between the inferior rectus and the medial rectus muscles (area 1) and between the medial rectus and the superior oblique muscles (area 2). In area 1, the ophthalmic artery crosses over the optic nerve in 90% of the cases. The anterior ethmoidal artery was observed inferior to the superior oblique muscle. In area 2, the posterior ethmoidal artery was located superior to the superior oblique muscle in all cavities. No middle ethmoidal artery was identified. The origin of the supraorbital artery was found between the two ethmoidal arteries. Conclusions: The anatomical understanding of the intraorbital origin of the arteries of the ophthalmic artery allows perform two surgical approaches through the media orbital wall.

ABSTRACT

The human nervus terminalis (terminal nerve) and the nerves to the vomeronasal organ (VNON) are both associated with the olfactory nerves and are of major interest to embryologists. However, there is still limited knowledge on their topographical anatomy in the nasal septum and on the number and distribution of ganglion cells along and near the cribriform plate of the ethmoid bone. We observed serial or semiserial sections of 30 fetuses at 7–18 weeks (crown rump length [CRL], 25–160 mm). Calretinin and S100 protein staining demonstrated not only the terminal nerve along the anterior edge of the perpendicular lamina of the ethmoid, but also the VNON along the posterior edge of the lamina. The terminal nerve was composed of 1–2 nerve bundles that passed through the anterior end of the cribriform plate, whereas the VNON consisted of 2–3 bundles behind the olfactory nerves. The terminal nerve ran along and crossed the posterior side of the nasal branch of the anterior ethmoidal nerve. Multiple clusters of small ganglion cells were found on the lateral surfaces of the ethmoid's crista galli, which are likely the origin of both the terminal nerve and VNON. The ganglions along the crista galli were ball-like and 15–20 µm in diameter and, ranged from 40–153 in unilateral number according to our counting at 21-µm-interval except for one specimen (480 neurons; CRL, 137 mm). An effect of nerve degeneration with increasing age seemed to be masked by a remarkable individual difference.

ABSTRACT

RESUMEN: La necesidad de unificar criterios respecto a los nombres de las estructuras anatómicas ha sido una permanente preocupación de los anatomistas del mundo, de tal manera que a partir de 1895 se inicia un proceso de estandarización y normalización de la terminología anatómica mundial. Se publica la Nomina Anatomica tratando de nominar las estructuras con un solo nombre en latín y se suprime los epónimos y homónimos. En la actualidad la Terminologia Anatomica sustituye a la Nomina Anatomica, con las mismas características, pero con la adición del término en el idioma de cada país. Sin embargo, persisten algunos errores desde la elaboración de la Nomina Anatomica y que se mantienen en Terminologia Anatomica, derivados tanto de la estructura gramatical latina, principalmente en el número y género, así como de la descripción de algunas estructuras anatómicas. Este es el caso de los ramos del nervio nasociliar, específicamente del ramo etmoidal anterior y del ramo infratroclear. Para el efecto se realizó una revisión de la descripción del nervio nasociliar y sus ramos terminales, se compararon entre sí y con los nombres que aparecen en la Terminologia Anatomica, para verificar que tanto la descripción como la construcción gramatical latina sean correctas. Se encontraron errores en la estructuración gramatical y jerárquica del ramo nasal interno, así como la supresión de los ramos palpebrales superior e inferior del nervio infratroclear, por lo que proponemos el cambio del término codificado con A14.2.01.031 a Ramus nasalis internus y la adición de los nombres Ramus palpebralis superior y Ramus palpebralis inferior.


SUMMARY: The need to unify criteria regarding the names of anatomical structures has been a permanent concern of anatomists worldwide. Therefore, and beginning in 1895 a standardization and normalization process of world anatomical terminology was initiated. The Nomina Anatomica is published in an attempt to name the structures with a single name in Latin and the eponyms and homonyms are deleted. Today the Terminologia Anatomica replaces the Nomina Anatomica, with the same characteristics, but with the addition of the term in the language of each country. Nevertheless, some errors persist from the Nomina Anatomica that remain in Terminologia Anatomica, derived from both the Latin grammatical structure, mainly in the number and gender, as well as the description of some anatomical structures. This is the case of the nasociliary nerve branches, specifically the anterior ethmoidal branch and the infratroclear branch. For this purpose, a review of the description of the nasociliary nerve and its terminal branches was made, they were compared between each other, and with the names that appear in the Terminologia Anatomica, to verify that both the description and the Latin grammatical construction are correct. Errors were found in the grammatical and hierarchical structure of the internal nasal branch, as well as the suppression of the upper and lower palpebral branches of the infratrochlear nerve. Therefore, we propose the change of the coded term with A14.2.01.031 to "Ramus nasalis internus" and the addition of the names "Ramus palpebralis superior" and "Ramus palpebralis inferior".

ABSTRACT

To investigate the morphologic characteristics of the retromaxillary posterior ethmoid.A total of 103 outpatients encountered in our hospital during March 2012 and December 2012,who completed paranasal sinus CT examination,were included in this study.Patients had no sinus trauma,surgery or tumor history.Their paranasal sinus CT scans were analyzed from scheduled axial and coronal plane.The incidence and imaging features of the retromaxillary posterior ethmoid were observed.The retromaxillary posterior ethmoid(RMPE)was the posterior ethmoid cell that expanded along the lamina papyracea toward the infraorbital region.RMPE was located behind the posterior wall of the maxillary sinus and under the orbital floor.The occurrence rate of the RMPE was 74.3%.The ethmomaxillary septum is the bony septum the between the maxillary sinus and posterior ethmoid.Anatomical confirmation of RMPE is based mainly on the presence of the ethmomaxillary septum.RMPE is located at the back of ethmomaxillary septum.The sagittal angulation of the ethmomaxillary septum ranged from 22 to 87 degrees,with an average of(50.34±12.10)degrees.The ethmomaxillary septum is important for anatomic recognition of the RMPE.Accurate identification of the RMPE before ESS can help improve the removal of the posterior ethmoid sinus.

ABSTRACT

Los osteomas fronto-etmoidales son los tumores benignos más frecuentes de los senos paranasales, pudiendo evolucionar con complicaciones por compresión de estructuras adyacentes. Se presenta el caso de una paciente de 63 años de edad, que consultó por aumento de volumen nasofrontal, cefalea y diplopía. Tras el examen clínico, se evidenció una asimetría facial con lateralización del bulbo ocular derecho y exoftalmo. La tomografía de los senos paranasales mostró una lesión que ocupa parcialmente el seno frontal, etmoidal y parte de la cavidad nasal. Los cuidados anatómicos y planificación quirúrgica se desarrollaron en un modelo estereolitográfico mientras que la cirugía de exéresis total se realizó con ayuda del sistema piezoeléctrico. El examen histológico confirmó el diagnostico de osteoma. Se obtuvo una reconstrucción exitosa, recuperando totalmente simetría y función ocular.


Fronto-ethmoidal osteomas are the most frequent benign tumors of the paranasal sinuses, and may evolve with complications by compression of adjacent structures. The case is a 63-year-old female patient, who consulted about increased nasofrontal volume, headache and diplopia. After the clinical exam, she presented a facial asymmetry with lateralization of the right eyeball and exophthalmus. Computed tomography of the sinuses showed a lesion that partially occupies the frontal sinus, ethmoidal sinus and part of the nasal cavity. The anatomical care and surgical planning was developed in a stereolithographic model while the total excision surgery was performed with the help of the piezoelectric system. Histological examination confirmed the diagnosis of osteoma. A successful reconstruction is obtained, fully recovering symmetry and ocular function.

ABSTRACT

Los meningiomas del surco olfatorio representan el 10 por ciento de los meningiomas intracraneales, se originan de la lámina cribosa del etmoides, la sutura fronto-esfenoidal y el plano esfenoidal. Son tumores en su mayoría benignos y potencialmente curables, la recurrencia ocurre en grado variable siendo el grado de resección quirúrgica el predictor más importante de recurrencia. En este artículo se exponen los resultados alcanzados con el abordaje endonasal endoscópico extendido transcribiforme en pacientes con meningiomas del surco olfatorio en el servicio de neurocirugía del hospital clínico quirúrgico Hermanos Ameijeiras. La serie fue de 12 pacientes donde la cefalea, la anosmia y los trastornos neuropsicológicos fueron los síntomas predominantes. Los tumores tuvieron un tamaño ≥ a 6 cm en el 50 por ciento de los casos y con el abordaje endonasal endoscópico extendido transcribiforme se alcanzó una resección total con Simpson I en el 92 por ciento de los enfermos. Los límites del abordaje endonasal endoscópico en la fosa anterior se encuentran en constante extensión, siendo el abordaje endonasal endoscópico extendido transcribiforme la opción ideal y prometedora para los pacientes con Meningiomas del surco olfatorio.


Olfactory groove meningiomas represent 10 percent of intracranial meningiomas, originate from cribriform plate of ethmoid, frontal and sphenoid suture and the sphenoid plane. They are mostly benign and potentially curable tumors, the recurrence occurs in varying degree and the extent of surgical resection is the most important predictor of this recurrence. This article presents the results achieved with the transcribiform extended endoscopic endonasal approach in patients with meningiomas of olfactorygroove in neurosurgery department of the “Hermanos Ameijeiras” hospital. The series was of 12 patients where headache, anosmia, and neuropsychological disorders were the predominant symptoms. The tumors had a size ≥ 6 cm on 50 percent of the cases and with transcribiform extended endoscopic endonasal approach was reached total removal in 92 percent (Simpson I) of the patients. The limits of endoscopic endonasal approach for anterior fossa are in constant expansion, being the transcribiform extended endoscopic endonasal approach the ideal and promising option for patients with olfactory groove meningiomas.

ABSTRACT

Abstract Background: Orbital floor fractures are a common finding in facial trauma and may be accompanied by medial orbital wall fracture in 7 to 53% of the cases. Isolated medial wall fractures are rare and usually asymptomatic, being detected as incidental findings. case report: We report a 75 years old female consultingin the emergency room due to a left orbital trauma. An orbital CAT scan identified a fracture of the medial orbit wall that did not require treatment.


Resumen Introducción: Las fracturas del suelo de la órbita son habituales en los traumatismos faciales y entre un 7 y un 53% de los casos se asocian con fracturas de la pared medial. Pero las fracturas aisladas de la pared medial son infrecuentes y la mayoría asintomáticas, siendo un hallazgo habitualmente incidental. Sin embargo, ciertos signos de alarma (limitación de la movilidad del recto medial, siendo habitual que aparezca de forma retardada por isquemia del músculo debido al atrapamiento) pueden plantear una cirugía urgente. Descripción del caso: Presentamos un caso de una paciente de 75 años que acude al Servicio de Urgencias de nuestro hospital remitida por médico de atención continuada por traumatismo sobre órbita izquierda. A la exploración presenta importante hematoma periorbitario y malar, sin alteraciones visuales. En TC orbitaria se identifica fractura de la pared medial de la órbita que, en ausencia de clínica acompañante, no requiere tratamiento alguno.

ABSTRACT

PURPOSE: To describe a new technique for isolation of a mesenchymal stem cells (MSCs) population from the olfactory mucosa in rabbits. METHODS: Olfactory stem cells (OSCs) were retrieved from under the cribriform plate of the Ethmoid bone. Several assays were accomplished to characterize the cell population and attest its viability in vitro. The cells were submitted to flow cytometry with the antibodies CD34, CD45, CD73, CD79, CD90 and CD105 and also they were induced to differentiate in three lineages. Functional evaluation involved analysis of in vitro growth behavior, colony forming unit like fibroblasts (CFU-f) and cryopreservation response. Further transduction with Green Fluorescent Protein (GFP) was also performed. RESULTS: The OSCs showed mesenchymal features, as positive response to CD34, CD73 and CD90 antibodies and plasticity. Additionally, these cells have high proliferated rate, and they could be cultured through many passages and kept the ability to proliferate and differentiate after cryopreservation. The positive response to the transduction signalizes the possibility of cellular tracking in vivo. This is a desirable feature in case those cells are used for pre-clinical trials. CONCLUSION: The cells harvested were mesenchymal stem cells and the technique described is therefore efficient for rabbit olfactory stem cells isolation.

ABSTRACT

OBJECTIVE@#To investigate the role of anatomical abnormalities in non-sinusitis-related rhinogenous headache and to evaluate effects of nasal endoscopic surgery for non-sinusitis-related rhinogenous headache.@*METHOD@#Sixty-eight patients diagnosed as non-sinusitis-related rhinogenous headache were selected in this study. They were treated with nasal endoscopic surgery after failed long-term medical treatment. Data from this group were analyzed retrospectively.@*RESULT@#Multiple anatomical abnormalities were noted by endoscopy and sinus computed tomographic scans in the 66 patients. These included nasal septum deviation in 46 cases (67.6%), middle turbinate gasfication in 20 cases (29.4%), protruding ethmoid bulla or uncinate processor in 10 cases (14.7%) and abnormal middle turbinate in 8 case (11.8%). Fifty-six (82.4%) patients showed significant improvement after surgery.@*CONCLUSION@#Non-sinusitis-related rhinogenous headache can be significantly minimized with individual nasal endoscopic surgery, as long as a precise identification of the etiologic anatomical factor can be made.

ABSTRACT

IgG4-related sclerosing disease (IgG4-RSD) is characterized by extensive IgG4-positive plasma cell and T-lymphocyte infiltration of various organs. However, the nasal cavity is an extremely rare site of involvement. The authors experienced three cases of igG4-RSD in the nasal cavity. A 54-year-old woman presented with a nasal cavity mass on endoscopic exam and computed tomography (CT) revealed not only a hypoenhancing mass in the right nasal cavity but also a pituitary gland macroadenoma. Endoscopic removal and endoscopic TSA were performed. A 20-year-old man diagnosed with chronic sinusitis, underwent endoscopic sinus surgery. A 26-year-old woman showed thickening of the nasal septum and cribriform plate, and an infiltrating soft tissue lesion in right the alveolar process on CT and an endoscopic biopsy was performed. Pathologic specimens of all cases showed IgG4-positive plasma cell infiltration, consistent with IgG4-RSD. Serum IgG4 levels were checked in two of the cases, and the results were within normal range. All cases were further treated with methylprednisolone and all showed clinical improvement.

ABSTRACT

The "nasal swell body" (NSB) or septal turbinate is a distinct structure of the anterior nasal septum that is observed on endoscopic and radiographic examination. It is primarily a glandular rather than a venous formation that is comprised of septal cartilage, bone, and thick mucosal lining. It is commonly found in patients with symptoms of chronic sinusitis and allergic rhinitis, and is linked to septal deviation. Space occupying lesions of the septum such as tumors, mucoceles, and pneumatization of the septum can lead to anatomical and functional disorders such as nasal obstruction and sinusitis, while more serious clinical conditions can develop when these lesions are combined with the NSB. Recently, there has been emphasis on the functional aspects of the NSB. It is especially being emphasized for clinicians to pay attention to the NSB and its connection with the stuffy nose. We report an interesting case of the NSB combined with pneumatization of the perpendicular plate of the ethmoid bone causing severe nasal obstruction and repetitive sinusitis along with a literature review.

ABSTRACT

Introduction: The removal of ethmoidal tumors with secondary extension to the cranial base and/or facial region involves a high complexity and it is associated to a high morbility. Objective: To determine the results of craniofacial surgery in patient with ethmoid extended tumors. Methods: It was carried out a traverse retrospective descriptive study. The sample was conformed by the patients intervened surgically of anterior cranial base lesions by means of a combined craneofacial surgery during the period: January of the 2009 to January of the 2012 in the National Institute of Oncology and Radiobiology with a 2 year pursuit. Descriptive statistical variables were used. Results: 20 patients were intervened. The age average was of 44,8 years. It prevail the masculine sex (65 percent). Nasal obstruction constitutes the most frequent presentation. Adenocarcinoma and epidermoid carcinoma constituted the most frequent malignant lesions. Inside the benign lesions prevail the invertedpapiloma. The techniques more employees were the bilateral frontal craneotomy and total etmoidectomy. The most frequent complication was the cerebrospinal fluid leak. The 2 years overall survival in patients with malignant lesions was 35 percent. Conclusions: A high number of complications was identified but they didn’t affect the survival neither the quality of life. An acceptable rate of survival was achieved in malignant lesions.

ABSTRACT

The olfactory groove schwannoma is a quite rare tumor. We report a case of a 49-year-old woman with an olfactory groove schwannoma attached to the cribriform plate without olfactory dysfunction. She had no specific neurological symptoms other than a headache, and resection of the tumor showed it to be a schwannoma. About 19 months after the operation, a follow-up MRI showed no evidence of tumor recurrence. Surgical resection through subfrontal approach could be one of the curative modality in managing an olfactory groove schwannoma. An olfactory groove schwannoma should be considered in the differential diagnosis of anterior skull base tumors.
