Incidence of Maxillary Sinus Abnormalities in Asymptomatic Patients: A CBCT Study
UNIVERSITY JOURNAL OF DENTAL SCIENCES
Background: Cone beam computer tomography (CBCT) when imaged for maxillary jaw generally depicts maxillary sinus. This region is frequently neglected by dentist and maxillofacial radiologist. Signs and symptoms in odontogenic diseases of the jaw and the maxillary sinus may overlap each other. A dental surgeon primarily encounters these lesions in routine dental radiographs.. Aim: The present study was undetaken to evaluate the occurrence of maxillary sinus anomalies in CBCT images of asymptomatic patients and to determine their prevalence, type and location. Materials and methods: Study consisted of 256 CBCT images of the patients depicting maxillary sinus who has been advised limited volume CBCT as part of routine dental investigation for implant planning, orthodontic assessment, oral surgical procedure, oral pathology etc.. The CBCT images were scrutinized for various maxillary sinus pathologies like mucosal thickening, opacification, polyp and retention pseudocyst Resul...

To analyze the anatomical findings and alterations of the maxillary sinus in asymptomatic patients observed by cone beam computed tomography. Materials and Methods: A cross-sectional retrospective study of the anatomical variations and alterations of the maxillary sinus was made in 160 patientsd71 males (44.3%) and 89 females (55.6%), with an age range of 18 to 74 yearsdmeasuring the thickness of the Schneiderian membrane and the cortical thickness of the lower margin of the maxillary sinus (in its most caudal portion), and correlations among the different study variables were assessed. Results: Sinus pneumatization was the most frequent anatomical finding (81.3%). A negative correlation was observed between the thickness of the Schneiderian membrane and the presence of Underwood septa (P , 0.005). Mucosal thickening of more than 2 mm was directly correlated with the presence of maxillary sinus lesions (opacification, discontinuity of the floor of the sinus, polypoid lesions, or air-liquid levels). Conclusion: The presence or absence of septa seems to be related to the thickness of the Schneiderian membrane.

OBJECTIVES. To assess the presence of anatomic variations and pathology of the maxillary sinus using cone beam computed tomography (CBCT) of the maxilla where pre- implant surgery is planned. MATERIAL AND METHODS. This retrospective study evaluates a sample CBCT scans of 34 dental patients (68 sinuses). CBCT is used to assess maxillary sinus mucosa and outflow and prevalence of septa. The mucosal thickening was measured and the sinus outflow was classified as open or obstructed. RESULTS. Mucosal thickening was found in 48.5%, septa in 20.6% and total opacity in 2.9% of the sinuses. Maxillary sinus outflow was blocked in 26.5% of the scans. Strong association between radiological signs of maxillary sinus ostium blockage and thickened mucosa was observed. CONCLUSIONS. Anatomic variations and lesions of the maxillary sinus were common findings in CBCT examinations of the maxilla required for dental preprosthetic planning. Routine CBCT scans, including maxillary sinus ostium are recomme...

Objective: To determine the range and prevalence of pathological conditions and demonstration of significant anatomical structures in the maxillary sinuses using the cone beam computerized tomographic (CBCT) scan. Methodology: Case series of 60 CBCT scans of the maxillae. Results: Forty (67%) of the scans were of female patients while the rest (20, 33%) were of males. Remarkably, the majority of the scans were requested for those patients who sought dental implant fabrication. Overall, 35 (58%) scans demonstrated pathological features while 8 (13%) demonstrated significant anatomical structures. Pathological features included mucosal thickening in 26 (43%), polypoid lesions in 9 (15%), total antral opacification in 1 (2%) and foreign body in 1 (2%). The commonest anatomic feature was dental root protrusion into the maxillary sinuses in 8 (13%). Conclusion: The CBCT imaging is an important tool for investigating the maxillary sinuses for pathology and the demonstration of the associated anatomic relations.

The proximity of the root tips of the maxillary posterior teeth to the maxillary sinus causes odontogenic infection to become a potential source of maxillary sinusitis. This study aims to evaluate the relationship between dental pathologies and maxillary sinus abnormalities using cone beam computed tomography (CBCT). Material and Method: In this study, 300 patients who applied to our clinic for any reason 600 maxillary sinus cone beam computed tomography images of the patient were analyzed retrospectively. Maxillary sinus diseases and dental pathologies categoized among themselves. Results: The age of all patients ranged between 18 and 77 years, with a mean age of 41.38 (±14.39) years. No pathology was detected in 359 (59.8%) of the maxillary sinuses examined which were considered healthy sinuses. The most common pathology in 241 (40.2%) of the maxillary sinuses in the imaging area was mucosal thickening (MT). A statistically significant relationship was detected between teeth with periapical lesions (PL) and MT (p<0.05). No statistically significant relationship was found between restorative applications, oro-antral fistula (OAF), periodontal bone loss (PBL), and maxillary sinusitis (MS) (p<0.05). Conclusion: Odontogenic infections and inflammatory events are the causes of maxillary sinus pathologies and may play a role in their formation. CBCT, maxillary posterior teeth and maxillary sinüs in demonstrating the relationship between and in the diagnosis of odontogenous sinus pathlogies is quite useful.

Odontogenic infections can directly trigger maxillary sinusitis. CBCT is an excellent choice for precise examination of maxillary sinuses and hard tissues within the oral cavity. The objective of this retrospective and the cross-sectional study was to analyze the influence of odontogenic conditions on the presence and intensity of maxillary sinus mucous membrane thickening using CBCT imaging. Moreover, periodontal bone loss and anatomic relationship between adjacent teeth and maxillary sinuses were assessed to evaluate its possible impact on creating maxillary thickening. The study sample consisted of 200 maxillary sinuses of 100 patients visible on CBCT examination with a field of view of 13 cm × 15 cm. The presented study revealed a significant influence of periapical lesions, inappropriate endodontic treatment, severe caries, and extracted teeth on the presence of increased thickening of maxillary sinus mucous membrane. In addition, an increase in the distance between root apices...

Objectives This study aimed to assess the maxillary sinus mucosal thickening and to associate them with odontogenic conditions using cone-beam computed tomographic (CBCT) images. Materials and methods CBCT images of 294 patients (143 female, 151 males; age range 18-78 years) with 588 maxillary sinuses were evaluated retrospectively. The anatomic relationship between maxillary sinuses and teeth was determined and classified. The presence of root canal fillings and the periapical lesions of these teeth was also recorded. Sinus mucosal thickenings were classified as grade 1 (normal) (< 2 mm), grade 2 (moderate) (2-10 mm), and grade 3 (severe) (> 10 mm). Alveolar bone loss was measured on all maxillary premolar/M teeth. Results More than 2-mm mucosal thickening (grade 2 and grade 3) in either one or both maxillary sinuses was found in 172 (58.5%) of the patients. The prevalence of mucosal thickening (> 2 mm) for maxillary sinuses with and without any periapical lesions was 42.1 and 53.6%, respectively (p < 0.05). The prevalence of mucosal thickening increased in patients with periodontal alveolar bone loss (p < 0.05). There was a significant correlation between mucosal thickening with age, gender and missing teeth (p < 0.05). Conclusions Multiple conditions, including periapical infection, root canal treatment, and close relationship maxillary teeth and sinus, may have a precursor effect on the occurrence of mucosal thickening in the maxillary sinus. Periodontal status and its role as a risk factor in triggering maxillary sinus infections should be also considered by not only dental professionals but also the medical professionals to plan for the treatment of maxillary sinus lesions. Clinical relevance Maxillary sinuses are significantly influenced by various odontogenic conditions, including periodontal bone loss, periapical lesions, and missing teeth, which may result in thickening of the maxillary sinus mucosa.

properly cited. Purpose. The aim of this paper is to report a case in which the cone beam computed tomography (CBCT) was important for the confirmation of the presence of maxillary sinus septum and, therefore, the absence of a suspected pathologic process. Case Description. A 27-year-old male patient was referred for the assessment of a panoramic radiograph displaying a radiolucent area with radiopaque border located in the apical region of the left upper premolars. The provisional diagnosis was either anatomical variation of the maxillary sinuses or a bony lesion. Conclusion. The CBCT was important for an accurate assessment and further confirmation of the presence of maxillary septum, avoiding unnecessary surgical explorations.
