Severity Of Osteitis Research Articles

The Impact of Osteitis on Quality of Life in Patients with Chronic Rhinosinusitis.

Introduction: Chronic rhinosinusitis (CRS) is a significant health problem worldwide with an estimated prevalence of 5-12% in the general population. Osteitis refers to inflammation of bone characterized by bone remodeling, neo-osteogenesis and thickening of adjacent mucosa. These changes are evidenced by specific radiological appearance on Computerized Tomography (CT) which may be localized or diffuse dependent on extent of disease. Osteitis act as a marker of severity in chronic rhinosinusitis and can significantly affect the patient's Quality of Life (QOL) proportional to its severity. Aim: To analyze the impact of osteitis on quality of life in patients with chronic rhinosinusitis as evidenced by pre-operative Sinonasal Outcome Test-22(SNOT-22) scores. Materials & Methods: 31 patients diagnosed to have chronic rhinosinusitis with co-existing osteitis were enrolled in this study based on computerized tomography scan Paranasal Sinuses (PNS) findings and graded as per the calculated Global Osteitis Scoring Scale. Accordingly, patients were categorised into those without significant osteitis, with mild, moderate and severe osteitis. Baseline quality of life in these patients was assessed using the Sinonasal Outcome Test-22 (SNOT-22) and its association with the severity of osteitis analysed.Results: There is a very strong correlation between severity of osteitis and quality of life in the study population based on the Sinonasal Outcome Test-22 scores (p = 0.000). The mean Global Osteitis score was 21.65 with standard deviation 5.66. Maximum score obtained was 38 and minimum score 14.Conclusion: • Osteitis has a significant impact on quality of life in patients with chronic rhinosinusitis. • Severity of osteitis has a direct relation to quality of life in chronic rhinosinusitis.

The Effect of Atopy on the Incidence of Osteitis in Patients with Chronic Rhinosinusitis.

BackgroundAtopy may not contribute directly to the pathogenesis of chronic rhinosinusitis (CRS) and could be a coexisting disease, but it may play a disease-modifying role in CRS. The aim of this study was to determine the effect of atopy on the incidence of osteitis in patients with CRS.MethodsA cross-sectional study at a tertiary center was conducted. Computed tomography of paranasal sinuses (CTPNS) of 75 CRS patients was analyzed. Skin prick test was used to determine the atopy among the CRS patients. The evaluation consisted of symptom score, Lund–Kennedy endoscopic score and CTPNS assessment by Lund Mackay (LM) staging system and Global Osteitis Scoring Scale (GOSS).ResultsAbout 54.7% of CRS patients had atopy (n=41), and 64% (n=48) had osteitis changes. No significant difference (p>0.05) was found for symptom and endoscopic scores in atopic and non-atopic CRS. Atopic and non-atopic CRS patients demonstrated comparable LM and GOSS scores (both p>0.05). Logistic regression analysis revealed that gender, nasal polyps and bronchial asthma were significantly associated with the incidence of osteitis. Significant correlation was found between LM and GOSS scores in atopic CRS (r=0.81, p<0.05). Correspondingly, both scores were found to be significantly correlated in non-atopic CRS (r=0.74, p<0.05).ConclusionAtopic sensitization has no effect on the incidence and severity of osteitis in patients with CRS. The present study suggests that osteitis occurs independently from the atopic pathway.

CLINICAL AND RADIOLOGICAL FEATURES OF THE MAXILLARY SINUS IN PATIENTS AFTER REMOVAL OF FUNGAL BALL AND THEIR IMPACT ON THE FREQUENCY OF SUBANTRAL BONE AUGMENTATION COMPLICATIONS.

Abstract. The mucoperiostitis and local osteitis are radiological symptoms of the fungal ball of the maxillary sinuses. The condition of the mucoperiosteum and the adjacent bone in the alveolar bay of the maxillary sinus predict the results of dental implantation and subantral augmentation. The endoscopic access to the sinus by the antrostomy in the middle meatus and infraturbinal have been used to avoid excessive tissue injury during the removal of the fungal ball.&#x0D; Aim: To assess the condition of the bone and mucoperiosteum of the maxillary sinus in patients with fungal ball after rhinosurgery by the antrostomy with additional osteoplastic infraturbinal access.&#x0D; Methods and materials: The data of 102 patients who underwent surgery for the fungal ball of the maxillary sinus were analyzed, and subsequently - subantral bone augmentation and dental implantation were performed. In patients of the first group (67 people) - endoscopic intervention was performed by antrostomy in the middle meatus, and in 2nd group (35 people) - additional osteoplastic infraturbinal access was used.&#x0D; Result: Computed tomography data were evaluated before endoscopic sinus surgery and before subantral augmentation. The frequency of signs and severity of osteitis according to Kannedy Osteitis Score, after the intervention did not change significantly, and was established as 0.90 ± 0.07 in patients of group №1 and 0.77 ± 0.08 – group №2. The total frequency of complications with subantral augmentation in the comparison groups was 17.91 ± 4.68% and 17.14 ± 6.37%, respectively. Symptoms of osteitis in patients with fungal ball of the maxillary sinus after endoscopic removal, in the first 4 - 6 months of observation tend to regress, but do not disappear.&#x0D; Conclusions: The incidence of osteitis in computed tomography in patients with maxillary sinuses fungal balls in 4.8 months after endoscopic removal tends to decrease and is 77.61 ± 5.09% when approach through the middle meatus and 74.29 ± 7, 39% in patients with combined infraturbinal approach. The use of additional infraturbinal approach in patients with a fungal ball does not adversely affect the results of subsequent subantral augmentation and dental implantation.

Порівняння частоти виявлення окремих рентгенологічних ознак при хронічному верхньощелепному синуситі грибкового та негрибкового ґенезу

The one of the most informative method of preoperative diagnosis of fungal paranasal sinuses is computed tomography. The radiological marker that allows to identify chronic sinusitis of fungal origin is an eclipse with hyperintensive inclusions. The sensitivity of this criterion for fungal ball is about 80%. In addition, a sign of recalcitrant chronic sinusitis is the presence of reactive changes in the bone wall of the sinus – "osteitis". The purpose of the work was to study the frequency of radiological signs of osteitis and areas of increased radiological density in the maxillary sinuses of the patients with chronic sinusitis of fungal and non-fungal etiology, to clarify the diagnostic significance of these symptoms in the differential diagnostics. Material and methods. The results of a retrospective study of computer tomography data of 60 people with chronic rhinosinusitis (intraoperative was verified fungal ball in the maxillary sinus space of 30 patients, other 30 patient had no signs of fungal etiology). Results and discussion. In patients with chronic rhinosinusitis of non-fungal nature, hyperintensive inclusions in the sinus were found in 13.3%, and signs of osteitis were detected in 36.7%, which was significantly less common than in patients with fungal processes, 83.3% and 80,0% respectively (p &lt;0,05). The presence of both of the radiological symptoms was observed in 63.3% of patients from the group of chronic rhinosinusitis in the presence of a fungal body in the space of the sinus and in 6.7% of cases the chronic rhinosinusitis of non-fungal etiology. The severity of osteitis according to KOS, in patients with a fungal body in the sinus was 0.71 ± 0.15 points, and 0.55 ± 0.2 points in patients without a fungus. The pathogenesis of osteitis in the cases of sinusitis with fungal origin is a violation of bone trophism, which develops due to periostitis after the influence of biologically active substances secreted by the fungus. The increase of radiation density in areas of osteitis indicates the predominance of osteogenesis over osteolysis in the inflammatory focus of the bone wall of the maxillary sinus. Conclusion. The frequency of detecting radiological signs of osteitis in patients with chronic rhinosinusitis of the maxillary sinus with fungal bodies was 80%, that was comparable to the frequency of detecting hyperintense inclusions in the lumen of the sinus in these patients (83.3%), and was significantly more than in patients with chronic sinusitis nonfungal etiology. The presence of radiological signs of osteitis of the bone wall of the maxillary sinus in computed tomography should be regarded as an additional symptom in the differential diagnosis of maxillary sinusitis of fungal origin

Osteitis in Chronic Rhinosinusitis.

Osteitis is recognized as a common factor in recalcitrant chronic rhinosinusitis (CRS). There is evidence for the association of osteitis with revision surgeries and CRS severity, in terms of higher Lund-Mackay scores. This is a narrative review on the osteitis in CRS patients. Evidence to date is inconclusive with regard to the etiology and pathogenesis of this bony thickening. Histopathology of osteitis in primary CRS is likely a process of neo-osteogenesis and bone remodeling. For better understanding, various associating factors have been studied including an inflammatory pattern of rhinosinusitis. Recent studies have associated osteitis with nasal polyps and tissue eosinophilia with the increase in periostin expression and P-glycoprotein mucosal expression. There is no association of osteitis to symptoms or quality of life. Osteitis is an outcome of neo-osteogenesis rather than inflammatory processes in CRS patients without a prior history of surgery. While CT has become a staple in osteitis assessment, the standards for grading osteitic severity remain in an experimental stage. There is no association between the presence or severity of osteitis at the time of surgery and clinical outcomes at 1year after surgery. This review provides a comprehensive overview of the pathogenesis, epidemiology, and correlation with clinical and biological factors of osteitis in CRS patients.

Impact of osteitis and biofilm formation and correlation between both in diffuse sinonasal polyposis in Egyptian adults; a prospective clinical and histopathologic study

BackgroundThe pathogenesis of diffuse sinonasal polyposis is still not completely established, possible explanations are osteitis, aeroallergens, fungal sinusitis and biofilms. There are no reports in Egypt about osteitis and biofilms in those patients. PurposeTo study the incidence and impact of osteitis and biofilms in Egyptian patients on diffuse sinonasal polyposis patients. Patients and methodsFifty patients (22 males, mean age of 30.68±7.24years) submitted to surgery for diffuse sinonasal polyposis. Computerized scan on sinuses ordered and scored by Lund–Mackay staging protocol, severity of Osteitis using the Global Osteitis Scoring Scale. Tissue samples were taken from diseased sinuses to be analyzed histopathologically for osteitis, and with scanning electron microscopy to detect bacterial biofilms. Another ten patients as a control scheduled for septoplasty or turbinectomy with no evidence of sinusitis, and tissue specimens were obtained 1cm behind the anterior end of inferior turbinate and processed in the same manner for biofilm comparison. Study designContemporary prospective cross-sectional cohort study. ResultsIn 70% (35/50) of the polyposis patients, histopathology was positive for osteitis. Biofilms were detected by electron microscope in 39 (78%). Two of controls (20%) were biofilm positive with a significant difference (p=0.035). The mean Lund–Mackay was 19.08±3.67 and mean osteitis score was 18.68±11.99. There was a significant correlation between Lund–Mackay and osteitis score (p<0.001) and between both and histopathologically proven osteitis (p=0.049), biofilms (p=0.005) and postoperative endoscopic healing (p=0.046) where increased soft tissue disease and osteitis and biofilm were associated with bad healing and vice versa. ConclusionOsteitis and bacterial biofilms underlie the majority of Polypoidal chronic rhinosinusitis and both correlated significantly. Scanning electron microscope is a good tool for detecting bacterial biofilms. Sinus surgery with surgical ventilation, mechanical disruption of biofilms and osteitis is a mandatory therapeutic choice with prolonged treatment with antibiotics and nasal wash.

Correlation between bacterial biofilms and osteitis in patients with chronic rhinosinusitis

Bacterial biofilms (BBF) and osteitis are potential contributors to the local inflammatory load in chronic rhinosinusitis (CRS). This study investigated the relationship between BBF and osteitis status in CRS patients. Prospective cohort study. Eighty-four CRS patients undergoing endoscopic sinus surgery and 22 control patients were enrolled in this study. Mucosal and bony samples from ethmoid sinus were obtained for confocal scanning laser microscopy and microscopic examination. Biofilm volume (BV), biofilm score (BS), histopathologic bony grade, Global Osteitis Scoring Scale (GOSS) score, and Hounsfield unit (HU) value on computed tomography were recorded. Associations between these parameters describing BBF and osteitis were assessed. The histopathologic bony grade 2 (0-3) versus 0 (0-3) (P < 0.001), GOSS score 4.5 (0-31) versus 0 (0-26) (P = 0.014) and HU value 431.5 (310-509) versus 354 (288-499) (P < 0.001) in patients with BBF were greater than those without BBF. The bony grade (r = 0.683, P < 0.001 and r = 0.664, P < 0.001), GOSS score (r = 0.314, P = 0.004 and r = 0.312, P = 0.004), and HU value (r = 0.539, P < 0.001 and r = 0.520, P < 0.001) were significantly increased with higher BV and BS. A total of 84.8% of the bone underlying mucosa with BBF had some form of osteitis in ethmoid sinus, and approximately 46.4% of CRS patients were from a subgroup with both BBF and osteitis. The volume of BBF correlated well with severity of osteitis in CRS patients.

The impact of neo‐osteogenesis on disease control in chronic rhinosinusitis after primary surgery

Osteitic bone is a feature of chronic rhinosinusitis (CRS), potentially playing a role in pathogenesis. Although seen after previous endoscopic sinus surgery (ESS), it is also a de novo feature in patients without prior interventions. In these patients, osteitis is associated with high tissue and serum eosinophilia. However, the impact of osteitis on prognosis is unclear. This study investigates the clinical and endoscopic outcomes between patients with and without osteitis after primary ESS. A prospective study of a cohort of previously unoperated patients with CRS undergoing ESS was performed. The sinuses were scored radiologically for osteitis using the Global Osteitis Score (GOS) and Kennedy Osteitis Score (KOS) preoperatively and were also scored dichotomously for the presence or absence of osteitis. Disease-specific quality of life (22-item Sino-Nasal Outcomes Test [SNOT-22]), nasal symptom score (NSS), endoscopic score (Lund-Kennedy), and clinical outcomes-including oral steroid use, frequency of nasal steroid irrigation, and infective exacerbations-were collected at baseline and 1 year postsurgery. The presence and extent of osteitis was assessed relative to clinical outcome. Fifty-three patients were included (41.5% female, age 47.4 ± 13.8 years), 42.9% of which had radiologic osteitis. There was no significant association between the presence or severity of osteitis at the time of surgery and SNOT-22, NSS, or endoscopy scores at 12 months postsurgery. However, the presence of osteitis was associated with the need for a course of oral steroid postsurgery (odds ratio [OR]=4.17; p = 0.026). High tissue eosinophilia could not predict this alone (p = 0.55). There was no significant relationship between osteitis and the frequency of steroid irrigations or infective exacerbations. Osteitis in CRS is associated with the degree of eosinophilia and as a independent process it was associated with the need for a course of systemic corticosteroid over a 12-month period, but did it not affect overall disease control.

Steroid‐independent upregulation of matrix metalloproteinase 9 in chronic rhinosinusitis patients with radiographic evidence of osteitis

Chronic sinonasal inflammation is associated with tissue remodeling, such as osteitis, which may be a marker of refractory disease; however, the pathophysiology of osteitis in chronic rhinosinusitis (CRS) is insufficiently understood. Ethmoid mucosa and bone samples were obtained from 35 medically refractory CRS patients and 9 control subjects. Quantitative real-time polymerase chain reaction (RT-PCR) was performed separately on bone and mucosa for matrix metalloproteinase 2 and 9 (MMP2, MMP9) and tissue inhibitor of matrix metalloproteinase 1 (TIMP1). Osteitis was classified as mild, moderate, or severe by measuring bone thickness of the maxillary, sphenoid, and ethmoid sinuses on multiplanar computed tomography (CT). Patients were classified based on severity of osteitis and compared to controls. Nine patients demonstrated radiographic evidence of osteitis (mild = 3, moderate/severe = 6). Bone PCR revealed biologically significant upregulation of MMP9 in all patients with CRS, but the magnitude of the upregulation decreased with severity of osteitis. Mucosa PCR showed upregulation of MMP9 in moderate/severe osteitis only. No significant changes were seen in MMP2 or TIMP1 regulation. This is the first study to evaluate the role of MMP in the bone and mucosa of patients with sinonasal osteitis. The pattern of expression suggests there may be a time- and tissue-dependent role for MMP9 in the pathophysiology of osteitis. In addition, MMP9 overexpression is seen despite preoperative oral and intranasal steroid use, suggesting that if MMP9 is an important factor in the development of osteitis then steroids may not be the best treatment in prevention of osteitis.

Global Osteitis Scoring Scale and chronic rhinosinusitis: a marker of revision surgery

Determine the incidence and severity of osteitis in patients with chronic rhinosinusitis using a new Global Osteitis Scoring Scale. Validation and prospective case-control study. Academic Tertiary Otolaryngology Department (Academic Medical Centre, Amsterdam). A prospective series of 102 patients undergoing a computed tomography (CT) sinuses as part of their evaluation for chronic rhinosinusitis between January and May 2008 (study group) and an age- and gender-matched control group of 68 non-rhinosinusitis patients. Seventy-eight of the chronic rhinosinusitis patients completed the nasal subset of the RhinoSinusitis Outcome Measure (RSOM-31) and visual analogue scales. Their CT scans were assessed for osteitis using a newly developed Global Osteitis Scoring Scale. A subsample of 35 scans were additionally scored by a second otolaryngologist and a radiologist. Global Osteitis Scoring Scale. The interrater variability of Global Osteitis Scoring Scale was low (average intraclass correlation coefficient: 0.94). Forty per cent of the chronic rhinosinusitis group and none of the control group had evidence of clinically significant osteitis. In the chronic rhinosinusitis group (102 patients), the severity of osteitis was correlated with Lund-Mackay (L-M) score (P<0.001), duration of symptoms (P<0.01) and previous surgery (P<0.001), rising in incidence with increasing number of previous operations. There was no association between osteitis and age, gender, smoking, co-existing asthma, allergy or Sumpter's triad. Additionally, there was no correlation between osteitis and symptom burden including headache, facial pain and nasal subset score of the RhinoSinusitis Outcome Measure. In patients with recalcitrant chronic rhinosinusitis who have undergone multiple surgeries in the past, the incidence of osteitis can be as high as 64%. It does not seem to be associated with more troublesome symptoms; however, it is strongly associated with previous sinus surgery, which may be a manifestation of a shared endpoint (underlying recalcitrant disease).
