Sinusitis maxilar iatrogénica por material de impresión dental / Iatrogenic maxillary sinusitis by dental impression material

Introducción: La etiología de la sinusitis maxilar comprende diferentes causas primarias y secundarias. Siempre es preciso descartar de inicio aquellas causas iatrogénicas consecuencia de intervenciones previas. Objetivo: Realizar una revisión de las diferentes causas de sinusitis maxilar, con énfasis en las causas raras iatrogénicas y en el protocolo de actuación. Presentación del caso: Paciente varón de 60 años que presenta episodios de sinusitis maxilar. Como antecedentes quirúrgicos se había realizado quistectomía maxilar, tratamiento de fístula oroantral secundaria y rehabilitación protésica posterior. Tras estudio radiológico inicial se halló una masa intrasinusal, compatible al tacto con material de impresión dental. Conclusiones: Es importante antes de cualquier rehabilitación protésica y de la toma de modelos confirmar la ausencia de fístula oroantral para evitar la intrusión de material extraño en el seno maxilar(AU)

Introduction: The etiology of maxillary sinusitis comprises a number of primary and secondary causes. It is always necessary to initially rule out iatrogenic causes resulting from previous interventions. Objective: Carry out a review of the different causes of maxillary sinusitis, with an emphasis on the rare iatrogenic causes and the clinical management protocols. Case presentation: A male 60-year-old patient who experiences episodes of maxillary sinusitis. Surgical antecedents include maxillary cystectomy, treatment for secondary oroantral fistula and posterior prosthetic rehabilitation. Initial radiological examination revealed an intrasinus mass compatible to the touch with dental impression material. Conclusions: Before any sort of prosthetic rehabilitation and the taking of models, it is important to confirm the absence of an oroantral fistula, to prevent the entrance of foreign material into the maxillary sinus(AU)

Rhinoorbitocerebral mucormycosis: a case report and literature review.

Mucormycosis is a rare oportunistic infection typically described in diabetic patients with a ketoacidotic status, as well as neutropenic patients. The infection is caused by a group of saprophytic fungi of the class Phycomicetes, being the most frequent ones the Rhizomucor, Rhizopus and Mucor. Its hystological findings include vascular trombosis and tissue necrosis, predominantly in the rino-orbito-cerebral area. Even though the frequency of presentation is very low, given its rapid evolution and severe consequences which include a high mortality rate, it is very important to be aware of the main features of the disease and treat it promptly. Although the diagnosis is based on the high clinical suspect, the computed tomography (CT) and the magnetic resonance image (MRI) plays an important role in determining the extension. The patients should receive treatment in a reference hospital so that a multidisciplinary approach is ensured. In this sense, we present a case of rhino-orbito-cerebralmucormycosis in a diabetic patient, recently treated in our Department. A comprehensive review of the literature has been performed to update the physiopathology and diagnosis. Finally, we describe the different treatment options focusing in the surgical approach, as well as the medical treatment with amphotericine and posaconzole.
