Odontogenic sinusitis: a comprehensive review

Abstract

Odontogenic sinusitis (OS) is a highly prevalent, underappreciated and underdiagnosed disease that has been known for over 100 years. Apical periodontitis, periodontal disease and iatrogenic extrusion of foreign bodies into the sinus are the main causes of OS. Although the prevalence of sinus pathosis of dental origin is still controversial, otolaryngologists recognize that in the presence of recalcitrant sinusitis, a dental origin should be considered and properly treated. Currently, cone-beam computed tomography is the gold-standard imaging technique to assess the relationship between dental conditions, especially apical periodontitis and sinus diseases, and whenever this association is detected, patients should be seen by both a dentist and an otolaryngologist in order to achieve complete recovery. This article reviews the current concepts regarding the definitions, diagnosis and management of OS from a clinical point of view.

Utilização de fibrina rica em plaquetas como coadjuvante no tratamento de infeção sinusal associada ao encerramento cirúrgico de comunicação oro-antral

“…É importante ressalvar que há diferentes abordagens para o tratamento desta condição clínica no seio maxilar, como por exemplo, o acesso pela parede lateral do seio maxilar para a curetagem da membrana sinusal e lavagem da área, sendo esta, a opção uma das mais comuns. 12 Porém, no presente caso, optou -se por uma abordagem mais simples e de menor morbidade para o paciente. Uma desvantagem é a visualização da região operada, em relação ao procedimento através do acesso de Caldwell -Luc.…”

Evaluation of factors affecting the association between thickening of sinus mucosa and the presence of periapical lesions using cone beam CT

“…Multiple odontogenic conditions including extractions, oroantral fistulas, periodontal and endodontic diseases and dental implants have been associated with OMS (Vidal et al 2017). Unless these odontogenic factors are removed by appropriate dental treatments, persistent sinus infections are generally managed with antibiotic therapy, which provides only temporary relief of symptoms (Fredriksson et al 2017).…”

“…Unless these odontogenic factors are removed by appropriate dental treatments, persistent sinus infections are generally managed with antibiotic therapy, which provides only temporary relief of symptoms (Fredriksson et al 2017). In order to avoid excessive antibiotic treatment or prevent possible progression to lifethreatening craniofacial infections, diagnosis of the true aetiology of maxillary sinusitis is of paramount importance (Vidal et al 2017, AAE 2018 Furthermore, it has been emphasized that it is important to distinguish maxillary sinusitis of endodontic origin (MSEO) from other odontologic sources because of the particular treatment requirements. MSEO is a new term used in recent literature and refers specifically to OMS secondary to endodontic inflammatory lesion(s), excluding sinusitis secondary to other odontologic conditions (AAE 2018).…”

“…Three-dimensional images derived from computed tomography (CT) or cone beam computed tomography (CBCT) have been shown to significantly contribute to the high detection rate of OMS as they provide multiplanar images of the maxillofacial region. CBCT is particularly recommended for identification of variations in the maxillary sinus and potential cause(s) of sinusitis due to its high-resolution and isotropic volume data at lower dose and cost (Maillet et al 2011, Shahbazian et al 2014, Simuntis et al 2014, Nagar & Gautam 2015, Zojaji et al 2015, Vidal et al 2017.…”

Effect of platelet-rich plasma on chronic odontogenic maxillary sinusitis: a pilot study

“…Patients with chronic periodontitis have an increased risk of developing maxillary sinusitis caused by intra-antral foreign bodies or by oroantral fistulas after tooth extraction [1,2]. According to the literature in the field, the incidence of this disease in the adult population is 10-12%, but according to the latest studies, the incidence increased to 41% [3][4][5]. So far, there is no gold standard in choosing the most suitable treatment method for this inflammatory process.…”
