“…Paranasal sinus exostosis (PSE) is a new diagnostic entity that appears to be a complication of nasal irrigations performed with cold solutions. To date, there has been only one case of exostoses involving the paranasal sinuses,6 observed in a CRS patient irrigating with cold gentamicin, reported in the otolaryngology literature. The purpose of this study was to report our experience with PSE and further characterize this unusual condition.…”

Paranasal sinus exostoses: An unusual complication of topical drug delivery using cold nasal irrigations

PSE is a rare condition that mirrors a well-described otologic process; exostoses of the external auditory canal. PSE appears to be a complication of cold nasal irrigations. It does not resolve with the halting of cold irrigations, but does not appear to progress further after intervention. PSE only affects postoperative patients. With the evolving trend to treat postoperative sinus disease topically, the clinician should be aware of the dangers of cold irrigations, and patients should be counseled accordingly.

“…Exostoses in the paranasal sinuses have been reported several times in the otolaryngology literature, but have not been described in the radiology literature to our knowledge [5-7]. The objective of this paper is to describe the CT features of this unusual entity, presumably related to chronic sinonasal irrigation.…”

“…22 Some authors have reported cases of exostoses in patients undergoing nasal irrigation therapy, thus correlating a cold temperature with a possible onset of exostosis. 23 The etiology and mechanisms of oral exostoses are unclear and there is no consensus among the investigators. Various authors have suggested several etiological factors such as genetic traits, en-vironmental factors, mastication and occlusal stress, inflammation, systemic diseases, and the post-menopausal period.…”

Palavras-chave:Exostose. Radiografia Panorâmica RESUMO Introdução: Exostoses nos seios paranasais têm sido muito mais relatados na literatura radiológica odontológica, apesar da extensa citação na literatura otorrinolaringológica. Objetivo: Neste relato de caso, encontramos uma exostose idiopática rara, que cresceu no seio maxilar. Relato de caso: Paciente negra de 68 anos, BGS, acompanhada pelo Serviço de Odontologia do Hospital do Câncer para tratamento de lesões orais (mucosite) e outras condições decorrentes da radioterapia e terapia hormonal (Tamoxifeno), apresentou neoplasia maligna da mama direita em 2015. Não foi realizada biopsia da exostose, pois a paciente está em tratamento e está sendo acompanhada pelo serviço do hospital. Realizaram-se radiografia panorâmica e exame clínico. Ao examinar os exames, foi possível notar uma imagem com dupla radiodensidade, mais radiopaca numa parte externa e menos radiopaca na parte interna, com aspecto de osso trabecular, circunscrito, unilocular, na região do pré-molar pediculado, no interior do seio maxilar esquerdo. Para melhor avaliação e hipótese diagnóstica, foi realizada uma tomografia computadorizada, aplicou-se uma ferramenta para mensuração da densidade do perfil da lesão, evidenciando-se que a suposta lesão invagina para o interior do seio maxilar e tinha densidade óssea semelhante ao osso da crista alveolar. Conclusão: Simultaneamente a outras lesões, as exostoses são lesões benignas, apresentam baixa agressividade e rara sintomatologia, sendo indicada exérese somente quando acomete a função, ou por motivos estéticos, ou quando não é possível a confecção de próteses. Muitos dos casos são diagnosticados de modo incidental e a partir de exames radiográficos de rotina em consultórios médicos ou odontológicos e devem ser acompanhados para análise e verificação de seu crescimento.ABSTRACT Introduction: Exostoses in the paranasal sinuses have been reported in a greater number in the dental radiological literature, despite the extensive citation in the otorhinolaryngology literature. Objective: This case report was a rare idiopathic expression that grew in the maxillary sinus. Case report: A 68-year-old black patient, BGS, followed up by the Odontology Service of Cancer Hospital for treating oral lesions (Mucositis) and other conditions resulting from radiation therapy and hormone therapy (Tamoxifen), presented malignant neoplasm at the right breast in 2015; an exostosis biopsy was not performed, since the patient is being treated and followed up by the hospital service. Panoramic radiography and clinical examination were performed. By analyzing the tests, it was possible to notice an image with double radiodensity, more radiopaque in the external portion and less radiopaque in the internal portion, with an aspect of trabecular bone, circumscribed, unilocular, in the region of pedunculated premolar, inside the left maxillary sinus. In order to have a better assessment and diagnostic hypothesis of the case, a CT scan was performed, a tool was applied to measure the...
