A retrospective analysis of the relationship between rhinosinusitis and sinus lift dental implantation.

ABSTRACT: Dental implants have been associated with the occurrence of postoperative rhinosinusitis. In some patients, preoperative sinus lifting must be performed to increase the chances of successful implant placement. This retrospective study examines the relationship of dental implants after sinus lifting with the occurrence of postoperative rhinosinusitis.A total of 268 dental implants were inserted in 94 patients (62 Males, 32 Females) between 2011-2013. The ages ranged from 29-71 (in males) and 33-64 (in females). Additionally, bilateral sinus lifing was performed in 51 patients, and unilateral sinus lifting was performed in 43 of the patients. Patients were evaluated for sinus pathology for a period of 5-47 months postoperatively using a satisfaction questionnaire, conventional radiographic examination, and nasal endoscopic examination.Four of the patients (4.2%) had a complication of postoperative sinusitis and were treated medically. In one patient, the implant was unsuccessful (even after treatment) and was removed. None of the patients needed surgery due to the sinusitis or any associated complications.The risk for postoperative rhinosinusitis was found to be higher in patients who suffer from chronic sinusitis and in cases in which a large amount of graft was utilized for sinus lifting. These predisposing factors need to be considered when evaluating patients for dental implants and sinus lift procedures.

Project description:BackgroundThe sinus lift (or sinus augmentation) is a common procedure to improve maxillary bone stock before dental implantation. Chronic rhinosinusitis (CRS) is a potential complication of this procedure and may be refractory to medical treatment. Functional endoscopic sinus surgery has previously been used to address CRS, however, results of previous studies indicated that implant removal is required. There are limited follow-up data available.ObjectiveThe purpose of this study was to characterize the long-term outcomes and efficacy of endoscopic sinus surgery for refractory CRS after sinus lift, including the ability to salvage dental implants.MethodsThis was a retrospective case series that described nine patients who, between June 2011 and September 2016, underwent endoscopic sinus surgery for CRS after a sinus lift procedure. The presenting symptoms of the patients, medical management, imaging results, operative procedures, and outcomes were reviewed.ResultsThe majority of patients developed symptoms (mucopurulent nasal drainage, facial pain and/or pressure, nasal congestion, and foul smell) within 3 months of implant placement and were treated with at least three courses of antibiotics before referral to an otolaryngologist. All the patients underwent wide endoscopic maxillary antrostomy, with no surgical complications or postoperative reports of infection. There was a statistically significant improvement in 22-item Sino-Nasal Outcome Test scores (t(8) = -2.908; p = 0.02) and discharge, inflammation, and polyps/edema endoscopic scores ([z = -2.539; p = 0.011) between pre- and postsurgical treatment. Four patients had their dental implants removed before presentation. Among the five patients who presented with intact dental implants, none required removal before or after functional endoscopic sinus surgery.ConclusionFunctional endoscopic sinus surgery was a reasonable and efficacious treatment option for patients who presented with paranasal sinus disease after a sinus lift. Dental implant removal may not be a requirement for successful treatment of CRS associated with sinus lift procedures.

Project description:BACKGROUND:Chronic rhinosinusitis (CRS) is one of the commonest chronic health problems among adults in the UK. Around 15% of CRS patients undergo functional endoscopic sinus surgery (FESS) annually after failing medical treatment. However, as incomplete resolution of symptoms or complications post-operatively is common, the post-operative management is considered to be as important as the surgery itself. A bioabsorbable corticosteroid-eluting sinus implant (CESI) (Propel®, mometasone furoate 370 µg) has been used as an alternative post-FESS treatment. OBJECTIVE:The objective of this study was to assess the cost effectiveness of the corticosteroid-eluting implant versus non-corticosteroid-eluting spacer following FESS for treatment of patients with CRS. METHODS:A decision tree model was developed to estimate the cost and effectiveness in each strategy. Costs and effects were estimated from a UK National Health Service (NHS) and personal social services perspective over a 6-month time horizon. Model pathways and parameters were informed by existing clinical guidelines and literature and sensitivity analyses were conducted to explore uncertainties in base-case assumptions. RESULTS:Over a 6-month time horizon, inserting CESI at the end of FESS is less costly (£4646 vs. £4655 per patient) and is the more effective intervention [total quality-adjusted life-years (QALYs) over 6 months 0.443 vs. 0.444] than non-corticosteroid-eluting spacers; hence, it is a dominant strategy. The probabilistic analysis results indicate that CESI following FESS has a 62% probability of being cost effective at the £20,000/per QALY willingness-to-pay threshold and 56% probability of being a cost-saving intervention. CONCLUSIONS:The use of CESI after FESS results in fewer post-operative complications than non-corticosteroid-eluting implants and may be a cost-saving technology over a 6-month time horizon. Although the cost of initial treatment with the CESI is greater, cost savings are made due to a reduction in the number of complications experienced.

Project description:The role of bacteria in chronic rhinosinusitis (CRS) is still not well understood. Whole microbiome analysis adds new aspects to our current understanding that is mainly based on isolated bacteria. It is still unclear how the results of microbiome analysis and the classical culture based approaches interrelate. To address this, middle meatus swabs and tissue samples were obtained during sinus surgery in 5 patients with CRS with nasal polyps (CRSwNP), 5 patients with diffuse CRS without nasal polyps (CRSsNP), 5 patients with unilateral purulent maxillary CRS (upm CRS) and 3 patients with healthy sinus mucosa. Swabs were cultured, and associated bacteria were identified. Additionally, parts of each tissue sample also underwent culture approaches, and in parallel DNA was extracted for 16S rRNA gene amplicon-based microbiome analysis. From tissue samples 4.2 ± 1.2 distinct species per patient were cultured, from swabs 5.4 ± 1.6. The most frequently cultured species from the swabs were Propionibacterium acnes, Staphylococcus epidermidis, Corynebacterium spp. and Staphylococcus aureus. The 16S-RNA gene analysis revealed no clear differentiation of the bacterial community of healthy compared to CRS samples of unilateral purulent maxillary CRS and CRSwNP. However, the bacterial community of CRSsNP differed significantly from the healthy controls. In the CRSsNP samples Flavobacterium, Pseudomonas, Pedobacter, Porphyromonas, Stenotrophomonas, and Brevundimonas were significantly enriched compared to the healthy controls. Species isolated from culture did not generally correspond with the most abundant genera in microbiome analysis. Only Fusobacteria, Parvimonas, and Prevotella found in 2 unilateral purulent maxillary CRS samples by the cultivation dependent approach were also found in the cultivation independent approach in high abundance, suggesting a classic infectious pathogenesis of odontogenic origin in these two specific cases. Alterations of the bacterial community might be a more crucial factor for the development of CRSsNP compared to CRSwNP. Further studies are needed to investigate the relation between bacterial community characteristics and the development of CRSsNP.

Project description:Describe detailed histopathologic findings from a cohort of patients with chronic rhinosinusitis and evaluate whether histologic measures correlate with baseline clinical factors.Cross-sectional study with planned data collection.Tertiary medical center.Adult patients with chronic rhinosinusitis were prospectively enrolled and demographic data and medical comorbidities recorded. Disease severity was measured by computed tomography (CT), endoscopy, Smell Identification Test (SIT), the Chronic Sinusitis Survey, Rhinosinusitis Disability Index, and SF-36 General Health Survey. Mucosal specimens were assessed for the presence of mucosal inflammation, including cellular (eosinophils, neutrophils, lymphocytes, mast cells, plasma cells, macrophages), epithelial (squamous metaplasia, basement membrane thickening, goblet cells), and stromal markers (subepithelial edema, fibrosis). Histopathologic findings were correlated to baseline clinical factors.A total of 147 subjects were enrolled with histologic samples available for review. Presence of inflammatory markers was diverse, with lymphocytes present in 100 percent of subjects, eosinophils in 49.7 percent, and neutrophils found in 0.7 percent. Total eosinophil counts correlated with the presence of nasal polyposis (r = -0.367; P < 0.001), asthma (r = 0.264; P = 0.001), and aspirin intolerance (r = 0.279; P = 0.001). Mucosal eosinophilia correlated with worse disease severity on CT (r = 0.414; P < 0.001), endoscopy (r = 0.376; P < 0.001), and SIT (r = -0.253; P = 0.002), with the highest correlations seen in subgroups without nasal polyps. Histopathologic findings did not significantly correlate with any quality-of-life measure.Mucosal eosinophilia correlates with objective disease severity as defined by CT, endoscopy, and SIT scores. Although other histologic markers of inflammation are present, none show similar correlations. The presence of mucosal eosinophils does not correlate with quality-of-life scores.
