Diagnostic value of 2D and 3D imaging in odontogenic maxillary sinusitis: a review of literature

This review aims to explore whether 3D imaging offers an added value in diagnosis of odontogenic sinusitis. Odontogenic maxillary sinusitis accounts for approximately 10-12% of maxillary sinusitis cases. Proper diagnosis of odontogenic sinusitis is based on a thorough dental and medical examination and crucial to ensure therapeutic efficacy. To establish the odontogenic cause of maxillary sinusitis, 2D and 3D imaging modalities may be considered, each presenting distinct advantages and drawbacks. The available research indicates that 2D imaging modalities may often mask the origin of odontogenic maxillary sinusitis. This limitation is particularly evident in the maxillary molar region, stressing the need for 3D cross-sectional imaging. The advent of low-dose cone beam computed tomography in dentistry may be particularly useful when odontogenic maxillary sinusitis is not responsive to therapy. Yet, it seems that more research is needed to validate its use in odontogenic maxillary sinusitis.     

Pathophysiology of sinusitis of odontogenic origin

Sinusitis of odontogenic origin, which is frequently encountered in routine otolaryngological and dental clinical practice, has been described as a reactive maxillary inflammation secondary to maxillary tooth infection or trauma to an odontogenic disease of maxillary bone, dental extractions, implant placement, or endodontic treatment impairing the integrity of the Schneiderian membrane. The aim of the present review was to investigate and discuss the most recent pathophysiological findings, predisposing odontogenic factors, microbiology, and the possible involvement of bacterial biofilms (BB) in the development of sinusitis. The narrative literature review showed that there might be a correlation between the bacteria present in pathological teeth in communication with the sinus and those found in infected sinus. The formation of a BB might be also involved in the etiopathogenesis of sinusitis of odontogenic origin. In conclusion, the true origin of odontogenic sinusitis is still unresolved. In clinical terms, the choice of suitable therapy depends on the characteristics of the biofilm. Further microbiological studies are required to better investigate the role of BB.     

Odontogenic sinusitis: a comprehensive review

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.     

Single-step surgical treatment of odontogenic maxillary sinusitis: A retrospective study of 98 cases

PurposeThe aim of this study was to review clinical and radiological presentation, surgery, and results of treatment in patients with chronic odontogenic maxillary sinusitis (OMS) treated with a single surgical procedure, including endoscopic sinus surgery (ESS) and oral surgical approaches to treat the odontogenic source of infection.Materials and methodsA retrospective case series analysis of 98 patients was performed. All the patients received ESS. 88 patients required oral surgical approaches.ResultsNasal symptoms were present in 58 patients (59.2%). Nasal endoscopy was positive in 65 patients (66.3%). A positive nasal endoscopy was significantly associated with nasal symptoms (p < 0.05). 60 patients (61.2%) had OMS of iatrogenic origin. Total opacification of the maxillary sinus was the most common radiological presentation (74.5%) and was significantly associated with nasal symptoms (p < 0.05). 91 patients (92.9%) had complete clinical and radiological resolution of the OMS.ConclusionsIatrogenic origin, sinonasal symptoms and positive clinical endoscopy are common in patients with OMS. Nasal symptoms were significantly associated with total maxillary sinus opacification and positive endoscopic clinical examination. Combining treatment of the odontogenic source of infection via an oral surgical approach and of the sinus inflammation by ESS appears to be sufficient for successfully treating patients with OMS.     

Clinical implications of taste thresholds in patients with odontogenic maxillary sinusitis

Patients with odontogenic maxillary sinusitis (OMS) often complain of reduced taste sensitivity as well as nasal obstruction. The filter paper disc method (the conventional gustatory test) was applied to nine patients who underwent sinus surgery to open the inferior nasal meatus and sinus drainage, on three different days: 1 day prior to surgery, 7 days postoperative, and 28 days postoperative. The same test was applied to nine non-clinical participants with or without clipping the nose to interfere with smooth nasal airflow on two different days. Acquired recognition thresholds for the four basic tastes of sweet, salty, sour, and bitter were assessed. In OMS patients, the recognition thresholds for all four tastes were markedly decreased at 7 and 28 days postoperative, and subjective taste sensitivity and the elimination of nasal obstruction was improved. The mean recognition threshold for the four tastes correlated negatively with taste satisfaction scores. Clipping the nose in non-clinical participants induced increases in gustatory detection and recognition thresholds. Despite the small sample size and different ages and sexes of the study subjects, it was demonstrated that nasal obstruction in OMS patients and nose clipping in non-clinical subjects reduce taste reactivity, and surgical intervention to promote nasal airflow recovers impaired taste reactivity.
