Surgical management of CRS was associated with significant improvement on objective and QOL measures; however, specific patient factors, in particular ASA and depression, predict poorer outcome. Preoperative CT may be a predictor of endoscopic and QOL outcome and deserves further study.

OBJECTIVES-1. To measure the proportion of patients with chronic rhinosinusitis (CRS) who experience clinically significant improvement after endoscopic sinus surgery (ESS) in a prospective, multi-institutional fashion. 2. To identify preoperative characteristics which predict clinically significant improvement in quality of life (QOL) after ESS. STUDY DESIGN-Prospective, multi-institutional cohort study SETTING-Academic tertiary care centers SUBJECTS & METHODS-302patients with CRS from three centers were enrolled between July 2004 and December 2008 and followed for an average of 17.4 months postoperatively. Preoperative patient characteristics, computed tomography (CT) scan, endoscopy score and pre-and postoperative quality of life (QOL) were collected. Univariate and multivariate analyses were performed.

Technological advancements have led to a trend of detecting sinonasal inverting papilloma before extension beyond the sinonasal region. Difference in recurrence rates was not observed between the endoscopic and the external approach groups. Recurrence rates are lower for primary resection versus secondary resection, regardless of surgical approach.

Multiple approaches to the management of CSF rhinorrhea can be successful. An endoscopic repair results in resolution of CSF rhinorrhea in the majority of cases. Patients with spontaneous CSF rhinorrhea, elevated BMI, lateral sphenoid leaks, and extensive skull base defects are at increased risk for recurrence. Alternative management options may need to be considered in these cases.

ObjectivesTo present current literature on the topic of odontogenic sinusitis.Data SourcePubMed literature search for odontogenic sinusitis.ResultsOdontogenic sinusitis is an inflammatory condition of the paranasal sinuses that is the result of dental pathology, most often resulting from prior dentoalveolar procedures, infections of maxillary dentition, or maxillary dental trauma. Infections are often polymicrobial with an anaerobe‐predominant microbiome requiring special considerations for antimicrobial therapy. Medical management and treatment of the underlying dental pathology remains a critical initial step in the treatment of odontogenic sinusitis, however recent literature suggests that a significant portion of patients may require endoscopic sinus surgery for successful disease resolution.ConclusionsThis review describes the essential epidemiological and etiological factors, relevant clinical findings and diagnostic modalities, microbiologic and antimicrobial considerations, as well as the medical and surgical treatment approaches commonly utilized for the management of odontogenic sinusitis.Level of EvidenceNA.
