Resolución Quirúrgica para Un Caso de Polisinusitis de Origen Odontogénico / Surgical Resolution for A Case of Polysinusitis of Odontogenic Origin

La celulitis orbitaria es una patología grave que está asociada con sinusitis paranasal. Éstas suelen presentar edema periorbitario, dolor, y movimiento extraocular restringido. La mayoría de los casos presentan pronóstico favorable, asociado a terapia antibiótica o drenaje quirúrgico. Las celulitis de origen odontogénico representan 2 a 5 % de todos los casos; se caracterizan por una diseminación del proceso infeccioso desde los ápices de las raíces, infectando al seno maxilar, llegando a la órbita a través de la fisura orbitaria inferior o a través de un defecto en el piso de la órbita. En el presente estudio se reporta el caso de un paciente masculino de 28 años que consulta por aumento de volumen periorbitario izquierdo con 4 días de evolución, posterior a exodoncia de segundo molar superior izquierdo. Al examen extraoral presenta aumento de volumen izquierdo con eritema periorbitario, proptosis ocular ipsilateral con visión conservada, y salida de líquido purulento por fosa nasal izquierda. En los exámenes de laboratorio e imagenológicos se pesquisa compromiso de seno maxilar, etmoidal y esfenoidal, decidiendo su hospitalización y manejo quirúrgico en tres tiempos operatorios, los cuales permiten acceso a pared anterior del seno maxilar y a espacio pterigoideo. Dentro de los diagnósticos de celulitis orbitaria pueden incluir reacciones alérgicas, conjuntivitis o herpes. Se excluyeron los diagnósticos mencionados debido a que no se observaron alteraciones dermocutáneas periorbitarias. Por el contrario, el compromiso unilateral, movimiento ocular alterado y doloroso indica que el cuadro abarcaba espacios profundos. La infección de senos paranasales posterior a una exodoncia es una complicación poco frecuente. Un diagnóstico temprano adecuado disminuye la morbilidad y mortalidad de esta condición. Debemos estar alertas a complicaciones posteriores en procedimientos realizados, tener conocimiento en diagnóstico y manejo de posibles evoluciones tórpidas en pacientes.

Orbital cellulitis is a serious pathology that is associated with paranasal sinusitis. These medical conditions usually present with periorbital edema, pain, and restricted extraocular movement. Most cases have a favorable prognosis, associated with antibiotic therapy or surgical drainage. Cellulitis of odontogenic origin represents 2 to 5 % of all cases. They are characterized by a spread of the infectious process from the apices of the roots, infecting the maxillary sinus, reaching the orbit through the inferior orbital fissure or through a defect in the floor of the orbit. The present study reports the case of a 28-year-old male patient, who consulted for a volume increase in left periorbital volume with 4 days of evolution, after extraction of the upper left second molar. Extraoral examination showed left volume increase with periorbital erythema, ipsilateral ocular proptosis with preserved vision, and discharge of purulent fluid from the left nostril. The laboratory and imaging tests showed compromise of the maxillary, ethmoid and sphenoid sinus deciding on hospitalization and surgical management in three operative times, which allow access to the anterior wall of the maxillary sinus and the pterygoid space. Diagnoses of orbital cellulitis may include allergic reactions, conjunctivitis, or herpes. These diagnoses were excluded because no periorbital dermocutaneous alterations were observed. In contrast, unilateral involvement, impaired eye movement, and pain indicate that the condition involved deep spaces. Paranasal sinus infection after tooth extraction is a rare complication. An early diagnosis adequately decreases the morbidity and mortality of this condition. We must be alert to subsequent complications in procedures performed, have knowledge in diagnosis and management of possible torpid evolutions in patients.

Tomografía computarizada en la identificación de la sinusitis odontogénica de origen endodóntico: reporte de un caso / Computerized tomography in the identification of odontogenic sinusitis of endodontic origin: report of a case

Objetivo: se presenta el caso clínico de sinusitis de origen endodóntico, conocida como síndrome en-doantral, haciendo énfasis en la dificultad de diag-nóstico con radiografía periapical y la importancia de la tomografía computarizada. Caso clínico: una mujer de 32 años, con antecedentes de apretamiento dental nocturno y sinusitis recurrente, fue remitida para evaluación endodóntica. El examen clínico reve-ló sensibilidad a la percusión y palpación en la unidad dental. La radiografía periapical no indicó lesión en el diente 16 y la prueba de sensibilidad pulpar fue ne-gativa, además, la tomografía computarizada reveló una extensa lesión periapical y comunicación entre la raíz del diente 16 y el seno maxilar, confirmada por la pérdida de la continuidad de la imagen hiperdensa en el suelo del seno, lo que llevó al tratamiento endo-dóntico. El control de la infección dental resolvió la sinusitis, resaltando la importancia del diagnóstico preciso y el tratamiento en casos de sinusitis odon-togénica. Conclusión: este caso destaca el valor de la tomografía computarizada como herramienta diag-nóstica crucial en contextos clínicos complejos (AU)

Objective: the clinical case of sinusitis of endodontic origin, known as endoantral syndrome, is presented, emphasizing the difficulty of diagnosis with periapical radiography and the importance of computed tomography. Clinical case: a 32-year-old woman, with a history of tooth clenching and recurrent sinusitis, was referred for endodontic evaluation. The clinical examination revealed sensitivity to percussion and palpation in the dental unit. The periapical radiograph did not indicate a lesion in tooth 16 and the pulp sensitivity test was negative, in addition, the computed tomography revealed an extensive periapical lesion and communication between the root of tooth 16 and the maxillary sinus, confirmed by the loss of continuity of the hyperdense image in the sine floor, which led to endodontic treatment. Dental infection control resolved sinusitis, highlighting the importance of accurate diagnosis and treatment in cases of odontogenic sinusitis. Conclusion: this case highlights the value of computerized tomography as a crucial diagnostic tool in complex clinical contexts (AU)

Isolated Meningitis and Lacrimal Gland Abscess due to Odontogenic Sinusitis: Case Report / Meningitis Aislada y Absceso de la Glándula Lagrimal debido a Sinusitis Odontogénica: Reporte de un Caso

ABSTRACT: Our objective was report an extremely rare case of isolated meningitis and suppurative dacrioadenitis as consequences of odontogenic sinusitis. We describe the diagnostic tools including imaging and culture, as well as surgical treatment and follow-up. Our final diagnosis was odontogenic sinusitis caused by Streptococcus Anginosus complicated by isolated meningitis and lacrimal gland abscess. Urgent surgical treatment to restore the paranasal sinuses and drainage of the lacrimal gland was performed. Culture from purulent material collected from maxillary sinus indicated the targeted therapy. Clinical assessment and imaging obtained 20 days after surgery demonstrated successful results. This case emphasizes the importance of evaluating intracranial complications of rinosinusitis, the need to search for a dental infection when a maxillary sinusitis is encountered, the key role of a thorough diagnostic workup in order to plan a comprehensive and effective surgical treatment, as well as targeted medical therapy.

RESUMEN: En este estudio se informa un caso extremadamente raro de meningitis aislada y dacrioadenitis supurativa, como consecuencia de sinusitis odontogénica. Describimos las herramientas de diagnóstico que incluyen imágenes y cultivo, como también el tratamiento quirúrgico y el seguimiento. El diagnóstico final fue de sinusitis odontogénica causada por estreptococo anginoso complicado por una meningitis aislada y el absceso de la glándula lagrimal. Se realizó un tratamiento quirúrgico de urgencia para restaurar los senos paranasales y drenar la glándula lagrimal. Se determinó el tratamiento de acuerdo a los resultados de cultivo del seno maxilar. La evaluación clínica y las imágenes obtenidas 20 días después de la cirugía demostraron resultados exitosos. Es importante la evaluación de las complicaciones intracraneales de la rinosinusitis además de la necesidad de considerar una infección dental frente a una sinusitis maxilar. Por otra parte, es clave una evaluación exhaustiva de diagnóstico para planificar un tratamiento quirúrgico completo y efectivo, así como el tratamiento médico.

Diagnóstico y tratamiento de la sinusitis maxilar odontogénica / Diagnosis and treatment of odontogenic maxillary sinusitis

RESUMEN Introducción: La patología sinusal inflamatoria e infecciosa puede comprometer la mucosa sinusal maxilar, etmoidal, esfenoidal o frontal, y su etiología es variada. Se ha observado que la patología odontológica es uno de los factores causales de la sinusitis maxilar, con una incidencia del 10% al 40% según diversas series de casos. El diagnóstico y tratamiento se debe realizar de manera interdisciplinaria entre las especialidades de otorrinolaringología y de cirugía maxilofacial. Se elaboró un documento descriptivo sobre la sinusitis odontogénica y orientador sobre su manejo, de acuerdo a una revisión de la literatura. Se realizaron búsquedas en las bases de datos PubMed, Lilacs y Google Académico, utilizando términos relevantes para la sinusitis odontogénica, con el fin de elaborar el documento. Se utilizaron 43 artículos, todos publicados desde el año 1986 hasta la fecha. Se concluye que la sinusitis odontogénica difiere tanto en la clínica como en la microbiología de otras enfermedades sinusales. El tratamiento se basa en el trabajo interdisciplinario e incluye cirugía endoscópica funcional, realizada por el otorrinolaringólogo, en conjunto con el tratamiento odontológico, siendo fundamental la buena comunicación entre ambos equipos.

ABSTRACT Introduction: Infectious and inflammatory sinus diseases have a varied etiology and can be associated to the maxillary, ethmoidal, sphenoidal and frontal sinuses. Dental pathology can be one of the etiological factors associated to maxillary sinus disease, with frequency rates of 10-40%. Diagnosis and treatment require interdisciplinary work, with participation of otorhinolaryngology and oral and maxillofacial surgery. The development of a descriptive document on odontogenic sinusitis and management guidelines according to literature review. Pubmed, Lilacs and Google Academic database were searched using terms relevant to odontogenic sinusitis, in order to prepare the document. 43 articles were used, all published from 1986 onwards. We conclude that odontogenic sinusitis differs clinically and microbiologically from other sinus pathologies. Treatment modalities are based upon interdisciplinary surgery, including functional endoscopic surgery done by otolaryngologists and dental treatment, being fundamental close communication between the two teams.

Bola fúngica de cavidades paranasales: serie de casos / Fungus ball of the paranasal sinuses: case series

RESUMEN Introducción La bola fúngica (BF) es una sinusitis fúngica no invasiva, con acumulación extramucosa de conglomerados densos de hifas de hongos en cavidades paranasales (CPN), afectando generalmente a mujeres inmunocompetentes. Objetivo Describir la presentación cínica, diagnóstico y tratamiento de una serie de pacientes con diagnóstico de BF de CPN. Material y método Estudio descriptivo retrospectivo de pacientes con diagnóstico histopatológico de BF sometidos a cirugía endoscópica nasal (CEN) en nuestra institución entre 2010 y 2016. Resultados Se incluyeron 20 pacientes (15 mujeres, 5 hombres), con edad promedio al diagnóstico de 64 años (35-86 años), la mayoría inmunocompetente (85%). El síntoma más frecuente fue dolor facial (8/20). Todos los pacientes fueron estudiados con tomografia computarizada (TC) de CPN, presentando calcificaciones en 70%. La ubicación más frecuente fue el seno maxilar (12/20) y luego esfenoidal (6/20). Se realizó CEN en todos los pacientes, combinándolo con Caldwell Luc en 3 de ellos. Los cultivos intraoperatorios resultaron negativos en el 75% de los pacientes. Conclusión La BF tiene presentación cínica inespecifica. Se sospecha en base a hallazgos imagenológicos en la TC de CPN y se confirma histopatológicamente, dado el bajo rendimiento de los cultivos. La CEN es la herramienta diagnóstico-terapéutica de elección, con baja tasa de recidiva local.

ABSTRACT Introduction A fungus ball (FB) is a non-invasive fungal sinusitis, consisting of extramucosal accumulation of dense fungal hyphae conglomerates, located in paranasal sinuses. It generally affects immunocompetent women. Aim To describe the clinical presentation, diagnosis and treatment in a series of patients diagnosed with FB of paranasal sinuses. Material and method Retrospective descriptive study regarding all patients with a histopathologic diagnosis of FB, who underwent endoscopic sinus surgery (ESS) in our institution between 2010 and 2016. Results Twenty patients (15 women, 5 men) were included, with a mean age at diagnosis of 64 years (35-86 years). Most were immunocompetent (85%). Facial pain was the most frequent symptom (8/20). All patients were studied with a sinus CT, finding paranasal calcifications in 70%. It predominantly involved the maxillary (12/20), and sphenoid sinus (6/20). All patients were treated with ESS, with a combined Caldwell Luc approach in only 3 of them. Intraoperative cultures were negative in 75% of patients. Conclusions Sinus FB has a non-specific clinical presentation. CT findings help suspect it, and it is confirmed with a histopathological study, given the poor efficiency of cultures. ESS is the diagnostic-therapeutic procedure of choice, with a low local recurrence rate.

Sinusitis maxilar por osteonecrosis asociada a bisfosfonatos en pacientes con cáncer de mama: serie de casos / Maxillary sinusitis associated to bisphosphonate-related osteonecrosis in patients with breast cancer: case series

Los bisfosfonatos (BF) son fármacos ampliamente utilizados como estabilizadores óseos en el tratamiento de metástasis óseas, osteoporosis, enfermedad de Paget, entre otras patologías, debido a sus efectos anti-tumorales y a la característica de inhibir la actividad osteoclástica. La osteonecrosis maxilar asociada a BF, hoy en día osteonecrosis maxilar asociada a fármacos (ONMF) es definida como la presencia de hueso expuesto, no-vascularizado y necrótico en la cavidad oral por un periodo mayor a ocho semanas, con una historia positiva de tratamiento con fármacos anti-reabsorción ósea (BP, inhibidores del ligando RANKL) y/o anti-angiogénicos y sin antecedentes de tratamiento con radiación o metástasis obvia en los maxilares. La frecuencia de ONMF es incierta. La mandíbula es más frecuentemente afectada por ONMF que el maxilar. Pocos casos de ONMF en el maxilar han sido descritos con un diagnostico de sinusitis maxilar simultáneo. Tres casos con sinusitis maxilar asociada a ONMF son presentados en este trabajo. Todos los pacientes fueron mujeres con una historia positiva de cáncer de mama y tratamiento con bisfosfonatos. Los primeros dos casos, desarrollaron ONMF después de una extracción del tercer molar maxilar. El tercer caso con ONMF en el maxilar, sólo tenía antecedentes de curetaje periodontal. Una tomografía computada fue realizada y mostró compromiso del seno maxilar en todos los pacientes. Modalidades diagnósticas para evaluar la extensión de la necrosis y el compromiso del seno, como también alternativas de tratamiento son descritas en este estudio. Finalmente, una revisión actualizada de la literatura es presentada.

Bisphosphonates are widely used as bone-stabilizers in the treatment of osseous metastases, osteoporosis, Paget's disease and others,due to their ability to inhibit osteoclast activity and anti-tumor effects. Bisphosphonate-related osteonecrosis of the jaw, nowadays medication-related osteonecrosis of the jaw (MRONJ), is defined as the presence of exposed, non-vascularized and necrotic bone tissue in the oral cavity over a period of 8 weeks with a current or previous history of treatment with antiresorptive (bisphosphonates, RANKL ligand inhibitor) and/or antiangiogenic agents, and no history of radiation therapy to the jaws or obvious metastatic disease to the jaws. The frequency of MRONJ is unclear. The mandible appears to be more frequently affected by MRONJ than the maxilla. Isolated cases of maxillary MRONJ have been described in wich a simultaneous sinusitis maxillaris was diagnosed. Three cases of MRONJ associated with maxillaris sinusitis are presented. All cases were females with a positive history of breast cancer and bisphosphonate therapy. The first two, developed MRONJ after a third molar upper extraction. The third case with MRONJ, had a history of periodontal curettage. A computed tomography was performed and showed a maxillary sinus compromise in all patients. Imaging modalities to evaluate the extent of the necrosis and the sinus compromise, as also treatment options were described in this study. Finally, an updated literature review is presented.

CBCT-based evaluation of integrity of cortical sinus close to periapical lesions

The purpose of the present study was to test the applicability of cone beam computed tomography (CBCT) to evaluate the integrity of the cortical sinus close to periapical lesions. Two observers analyzed samples of 64 alveoli of first molar roots in macerated swine maxillas prepared with perchloric acid to simulate periapical lesions. The specimens were evaluated using CBCT (55-mm high and 100-mm diameter cylinder at 0.2-mm voxel resolution) for the presence of oroantral communication (OAC) caused by the simulated lesions. Sensitivity, specificity, and accuracy were calculated. Fair values were obtained for accuracy (66%-78%) and good values for specificity (70%-98%), whereas the values for sensibility showed relevant variation (41%-78%). For this reason, the interobserver agreement score was weak. CBCT proved capable of evaluating the integrity of the cortical sinus (absence of oroantral communication) when it lies close to an apical periodontitis lesion. However, the low interobserver agreement reflects the difficulty in performing diagnoses when OAC is adjacent to a periapical lesion, using the acquisition protocol adopted in this research. This could be attributed to the high level of image noise.

Maxillary sinus ultrasound versus plain radiography and diagnostic antral washout in the diagnosis of maxillary sinus diseases

Maxillary sinus ultrasound has been found useful in diagnosis of maxillary sinus diseases. Is to compare the usefulness of diagnostic ultrasound, radiography of the maxillary sinuses with the results of he diagnostic wash out in detection of the maxillary sinus diseases. Fifty-five patients [109 maxillary sinuses] with suspected sinus diseases on clinical evaluation examined by ultrasonography, plain radiography and followed by diagnostic antral washout. The positive returns were 48.6% [53/109]. The sensitivity of the ultrasonography and plain radiography were [92.5%], [90.5%] respectively. The specificity of the ultrasonography and the plain radiography were [55%, 41%] respectively. The accuracy of the ultrasonography was [73.4] while of the radiography was [65%]. Sinus ultrasonography is harmless [no radiation], less expensive and can be used safely in childhood and pregnancy, and gives comparable results with plain radiography and antral washout in diagnosis of sinus diseases

Clinical versus radiological pointers of maxillary sinusitis in performing an aspirate in patients with fever of more than 10 days

The value of a diagnostic maxillary sinus aspirate in patients with fever of more than ten days with abnormal sinus x-ray findings is unclear. When the intrinsic medical side fails to find a cause for such a prolonged fever, after consuming all tests, yet finds suspicious sinus radiological changes, he will consider the otolaryngologist to lend a hand in aspirating the sinus for bacteriological examination. It is a well-known fact that maxillary sinus aspirate is a surgical procedure that is not risk free, besides its discomfort and invasiveness to the patient. Therefore, this procedure is not to be performed lightly for febrile patients with not rigid indications for applying it. This study was conducted to find out how significantly can the otolaryngologist relay upon the clinical signs and symptoms pointing towards an underlying sinus infection and not depending on sinus radiological changes in performing the procedure. Both the otolaryngologist and the intrinsic medical sides participated in this study. To start with, the medical side while investigating febrile subjects, running fever for more than ten days and failing to find a cause through the laboratory tests, but ending with a positive finding on sinus x-ray which could point to a possible underlying infection causing the fever. This is where such a patient was referred to the ENT side to participate in tackling the case. A careful history was collected along with a thorough examination. The radiological study was carefully interpreted and the findings recorded. The 51 maxillary sinus aspirate samples collected from 34 patients were sent for bacteriological culture. 86.4% of patients with a positive history of sinus and nasal symptoms yielded positive cultures, whereas only 8.3% with radiological changes and no symptoms of sinusitis had a positive culture. This study indicates that the symptoms of sinus disease in the febrile patient's history are the reliable parameter in directing the otolaryngologist in deciding upon a maxillary sinus aspirate, once those patients have a positive radiological change marking the possibility of a sinus cause for the fever

Ultrasonography versus radiography in the diagnosis of maxillary sinusitis

Water's view plain film radiography was compared with ultrasonography in the diagnosis of acute maxillary sinusitis in 50 patients at the Radiology Department of King Hussein Medical Centre in Jordan with clinical diagnosis of acute sinusitis. Ultrasound showed 100% concordance with plain radiographs reported as showing complete opacifications or an air fluid level, the only reliable plain film indicator of an inflamed antrum. We conclude that ultrasonography, which is non-ionizing, can provide an alternative to plain radiography in the initial investigation of maxillary sinusitis

Use of standard radiography to diagnose paranasal sinus disease of asthmatic children in Taiwan: comparison with computed tomography.

Paranasal sinus disease and bronchial asthma are frequently associated. Computed tomography imaging is currently the most reliable method for confirming the diagnosis of sinusitis. Due to the cost and amount of radiation during computed tomography, our aim was to analyze whether standard radiography, under computed tomography-control, had a reasonable degree of confidence in the diagnosis of sinusitis. Fifty-three asthmatic patients (42 males and 11 females) with a mean age of 9 years (range 4-14) were enrolled. We evaluated the maxillary sinuses, ethmoidal sinuses, frontal sinuses, and sphenoidal sinuses using standard radiography (Waters' view, Caldwell view, and lateral view) and compared with computed tomography (coronal views), the latter served as a standard. Computed tomography (CT) showed paranasal sinusitis in 58% (31/53) of the asthmatic children. Compared with the results of computed tomography, standard radiography revealed a sensitivity of 81.1% and a specificity of 72.7% for maxillary sinusitis. The sensitivity and specificity for ethmoidal, frontal, and sphenoidal sinusitis were 51.8%, 84.8%; 47.3%, 87.2%; and 40.8%, 93.3%, respectively. In 21 (40%) of the 53 patients, discrepancies were seen between the interpretations of standard radiography c and those of CT scans. In patients with maxillary sinusitis, the correlation between standard radiography and CT was good. However, ethmoidal, frontal, and sphenoidal sinusitis were poorly demonstrated using radiography. Standard radiography can be recommended as a screening method for maxillary sinusitis, but it is not recommended for the diagnosis of other paranasal sinusitis.

Evaluation of the results of inferior versus middle meatal antrostomy in the treatment of chronic maxillary sinusitis

In this work the results of inferior versus middle meatal antrostomy in the treatment of chronic and recurring maxillary sinusitis were evaluated by clinical, radiological, endoscopic and histopathological examination. It was found that chronic and recurring maxillary sinusitis respond better to an antrostomy in the middle meatus than to antrostomy done in the inferior meatus

Ultrasonography: a complementary diagnostic tool in chronic maxillary sinusitis

One hundred and six cases [64 males and 42 females] of Chronic maxillary sinusitis were investigated in out patients from September 1988 to December 1989. The results of Ultrasonography, X-rays and proof puncture were analysed. Confidence level with radiography in the presence or absence of exudative fluid was found to be 87 and 88 per cent respectively, while with Ultra-sonography a confidence level of 93.5 per cent and 98.7 per cent was noted in the presence or absence of fluid respectively
