Background: Odontogenic sinusitis (ODS) is distinct from non-odontogenic rhinosinusitis, and often requires multidisciplinary collaboration between otolaryngologists and dental providers to make the diagnosis. The purpose of this study was to develop international multidisciplinary consensus on diagnosing ODS. Methods: A modified Delphi method was used to assess for expert consensus on diagnosing bacterial ODS. A multidisciplinary panel of 17 authors with ODS expertise from 8 countries (8 otolaryngologists, 9 dental specialists) was assembled. Each author completed 2 of 3 surveys (2 specialty-specific, and 1 for all
Importance: Transnasal fiberoptic laryngoscopy (TFL) has been used to guide various in-office procedures for the past 3 decades. Publications on in-office laryngeal biopsy have concurred that this procedure is safe, feasible, and easy to perform. However, the accuracy of inoffice biopsy via TFL has not yet been established. The aim of this study was to examine this issue.Objective: To compare pathologic results obtained via in-office TFL with those of subsequent direct laryngoscopy to assess the accuracy of TFL as a diagnostic tool.Design: Prospective cohort study. Setting: Tertiary reference medical center.Participants: One-hundred two patients with suspicious laryngeal lesions.Intervention: All patients underwent in-office biopsies. Main Outcome Measures:All patients with malignant lesions were referred to appropriate services for treatment, and those with a diagnosis of a benign lesion or carcinoma in situ were referred for direct laryngoscopy for definitive diagnosis. The results of the pathologic testing on specimens from in-office and direct laryngoscopy were compared.Results: Adequate tissue for diagnostic purposes was obtained in 96 of 102 in-office TFL biopsies (94.1%). The biopsy results revealed invasive carcinoma in 34 patients (35.4%), carcinoma in situ in 17 patients (17.7%), and benign lesions in 45 patients (46.9%). All patients with benign lesions and carcinoma in situ were referred for biopsy of samples obtained using direct laryngoscopy, to which 57 patients agreed. The final pathologic results identified from the biopsies on direct laryngoscopy revealed that there was an underestimation of the TFL results in 30 of 91 patients (false-negative rate, 33.0%) and an overestimation in 1 patient (false-positive rate, 1.1%). The sensitivity of TFL biopsy compared with that of direct laryngoscopy biopsy was 69.2% and the specificity was 96.1%. Conclusions and Relevance:Transnasal fiberoptic laryngoscopy yielded low sensitivity in assessing suspicious lesions of the larynx. These results may indicate that direct laryngoscopy represents the definitive pathologic diagnostic procedure whenever the pathologic results of an in-office TFL procedure are interpreted as benign or as carcinoma in situ.
Juvenile angiofibroma (JA) is a benign, highly vascular tumor which is diagnosed on the basis of clinical and imaging features. It has a characteristic pattern of spread commonly involving the pterygopalatine fossa and pterygoid base. The mainstay of treatment is surgery, while radiotherapy is rarely used for the treatment of recurrent lesion. Endoscopic endonasal surgery is currently the treatment of choice for small to intermediate size JAs, and is feasible even for advanced lesions; however, this should only be practiced in well-experienced centers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
