Resultados clínicos e imagenológicos en pacientes con rinosinusitis crónica odontogénica / Evaluation of clinical and imaging results in patients with chronic odontogenic rhinosinusitis

INTRODUCCIÓN: La rinosinusitis crónica odontogénica (RSCO) es un proceso inflamatorio/infeccioso de la mucosa nasal y senos paranasales (SPN) de origen dental. Corresponde a una patología subdiagnosticada en la actualidad. El gold standard diagnóstico es la tomografia computarizada. Los tratamientos difieren, desde tratamiento médico aislado hasta médico-quirúrgico de SPN o combinados. OBJETIVO: Caracterizar los resultados clinicos e imagenológicos de pacientes con RSCO en función del tratamiento recibido, para establecer recomendaciones terapéuticas. Describir la frecuencia de subdiagnóstico de esta patología. MATERIAL Y MÉTODO: Estudio descriptivo, retrospectivo. Se incluyeron pacientes con diagnóstico clínico e imagenológico de RSCO entre los años 2013-2017 en un centro de atención médico privado, a los que se realizó una tomografía computarizada cone beam de control. Fueron excluidos aquellos con rinosinusitis crónica, cirugía endoscópica funcional (CEF) previa, cáncer, embarazadas, rechazo a tomografía computarizada cone beam, ausencia de imágenes preoperatorias y menores de 18 años. RESULTADOS: De un total de 27 pacientes, en los operados de CEF (n =24; 89%) la resolución total de los síntomas se logró en 20/24 (83%), resolución parcial 3/24 (12,5%) y persistencia de los síntomas 1/24 (4%). Discusión: De los pacientes con RSCO 22/27 (81%) no tenían reportado el foco dental en el informe radiológico a pesar de ser visible. Aquellos pacientes con sintomatologia postratamiento, hubo factores identificados como la bilateralidad, mala dentadura general, falta de combinación de tratamiento dental y CEF. CONCLUSIONES: La CEF combinada con tratamiento dental concomitante, tiene un alto grado de éxito radiológico y clínico en esta patología. No fue posible demostrar si siempre es requerida la exodoncia con cierre de fístula oro-antral o si se pueden seleccionar pacientes para un tratamiento más conservador.

INTRODUCTION: Chronic odontogenic rhinosinusitis (CORS) is an inflammatory/infectious process of the nasal mucosa and sinuses of dental origin. Actually, it corresponds to an underdiagnosed pathology. The gold standard diagnosis is computed tomography. The treatments differ, from isolated medical treatment to medical-surgical sinuses or combined. AIM: To characterize the clinical and imaging results of patients with CORS according to the treatment received, to establish therapeutic recommendations. In addition to describing the frequency of subdiagnosis of this pathology. MATERIAL AND METHOD: Descriptive, retrospective study. Patients with clinical and imaging diagnosis of CORS between 2013-2017 were included in a private medical care center, to whom a cone beam computed tomography control was performed. Those with chronic rhinosinusitis, previous functional endoscopic sinus surgery (FESS), cancer, pregnant women, rejection of cone beam computed tomography, absence of preoperative images and those under 18 years were excluded. RESULTS: Of all patients operated on FESS (n =24; 89%) the total resolution of the symptoms was 20/24 (83%), partial resolution 3/24 (12.5%) and persistence of the symptoms a 1/24 (4%). Discussion: 22/27 (81%) of patients with CORS had not reported the dental focus in the radiological report despite being visible. Those patients with post-treatment symptoms had identified factors such as bilaterality, general bad teeth, lack of combination of dental treatment and FESS. CONCLUSION: The FESS combined with concomitant dental treatment, has a high degree of radiological and clinical success in this pathology. It was not possible to demonstrate whether exodontia with closure of oroantral fistula is always required or if patients can be selected for a more conservative treatment.

Rinosinusitis recalcitrante por granulomatosis eosinofílica con poliangeítis: reporte de un caso clínico y revisión de la literatura / Chronic recalcitrant rhinosinusitis secondary to eosinophilic granulomatosis with polyangiitis: report of a case and literature review

RESUMEN Se expone el caso de un paciente de 40 años con diagnóstico de granulomatosis eosinofílica con poliangeítis subyacente a una rinosinusitis crónica recalcitrante. Se describe el caso y se discuten aspectos relevantes de la literatura al respecto.

ABSTRACT We report the case of a 40-year-old man with diagnosis of chronic recalcitrant rhino-sinusitis secondary to eosinophilic granulomatosis with polyangiitis. We described the case and discuss relevant aspects of the literature about it.

Correlation of radiologic evidence of rhinosinusitis with the criteria set by task force for rhinosinusitis [TFR]

The development of consensus guidelines for diagnosis and treatment for rhinosinusitis has been significant challenge for otolaryngology and primary care providers. A major break through emerged in 1997 when task force for Rhinosinusitis [TFR] set forth consensus diagnostic guidelines for acute, sub-acute and chronic sinusitis, later revised in 2003. But still there is no gold standard identified to diagnose chronic rhinosinusitis. In our study we have seen the degree of agreement between TFR criteria for CRS and CT scan paranasal sinuses findings. To examine the degree of agreement between the task force criteria for chronic rhinosinusitis and CT scan findings for rhinosinusitis. All the patients had two major or one major with two minor symptoms defined by TFR criteria were enrolled. All the patients underwent assessment as per TFR criteria and diagnosed positive or negative. CT scan paranasal sinuses of all the patients were also done and were assessed as per Lund Mackay CT scoring system. Degree of agreement between these two diagnostic modalities was seen. Forty patients were enrolled for this study. Degree of agreement between TFR criteria for CRS Lund Mackay CT scati scoring system was found to be 0.615 [+1-95% Cl + 0.54 1- +/- 0.689].When we saw the sensitivity and specificity of TRF criteria against CT scan it was calculated to be 88% and 100% respectively. Positive and negative predictive value for this criteria was came out to be 100% and 25%. Degree of agreement between TFR criteria and CT scan for CRS is satisfactory. TFR criteria is highly specific to diagnose CRS
