Nose is the central part of mid-face and has an important functional, aesthetic and psychological role. The first modern and accurate descriptions of the paranasal sinuses can be traced to the works of the late 19th century Austrian anatomist Emil Zuckerkandl. In our study we tried to relate deviated nasal septum (DNS) with occurrence of sinusitis and its effect on volume of the maxillary sinus. It is a pioneer study in the field of otolaryngology and not many studies have been conducted on this topic. This is a cross sectional study involving patients with deviated nasal septum and having symptoms of sinusitis like fever, general malaise, body ache, headache, pain, tenderness, nasal discharge and post nasal discharge. The study was conducted at the department of otolaryngology at a tertiary care center on 84 subjects out of which 71 patients got CT scan done, which were included in the study. All subjects having Grade 5 and 6 DNS showed blocked osteomeatal complex (OMC) on CT scan while in Grade 2 the occurrence was only 50%. This finding was suggestive of increase in incidence of OMC block with increasing grade of DNS. The maxillary sinus volume for the cases was seen maximum in range of 9.1-10 cu mm by software and in the range of 8.1-9 cu mm for geometric analysis. Cases with Grade 2 DNS showed maximum cases in volume range of 11.1-12 followed by 9.1-10. On the other hand volume by geometric analysis showed equal cases in range 8.1-9 and 10.1-11. The study showed strong association of blocked OMC with high grade DNS. It also showed reduced sinus volume in higher grades of DNS. Further studies are needed in this field with a higher number of subjects to establish the relation between decreased volume of maxillary sinus and grade of DNS.

BACKGROUND
Accessory maxillary ostium (AMO) has a major role to play in the aetiology of maxillary sinusitis. Mucosal thickening is one of the key radiographic features of chronic maxillary sinusitis. The aim of this study was to identify the location of the AMOs and investigate the association between Mucosal Thickening [MT] and AMO using Cone Beam Computed Tomography [CBCT].
METHODS
CBCT scans of 400 maxillary sinuses from the records of 200 patients who seeked various dental treatments at the Thumbay Dental Hospital, Gulf Medical University, Ajman, United Arab Emirates were evaluated. The incidence, anatomical position and maximal length of accessory maxillary ostia (AMO) in the maxillary antrum were reviewed using CBCT by two examiners. The association between MTs and AMOs were also analysed.
RESULTS
Among the 200 CBCT scans, 131 belonged to male patients and 69 scans belonged to female subjects within the age group of 18-65 years (mean age 41.32 years). AMOs were found in 142 maxillary antra (35.5 %). The inter-observer reliability for using CBCT to detect AMO was (k = 0.83). There was no significant difference in the frequency of AMOs when the age (P = 0.19) and gender (P = 0.54) distribution were considered. Sinuses with AMOs, showed significantly greater frequency of MTs (p = 0.001). AMOs with maximal length of less than 1mm were most commonly observed (51.40 %). AMOs with larger greater maximal length were associated with higher degrees of MT. The location of the AMOs, were not affected by the degree of MT.
CONCLUSIONS
The study demonstrates a clear association between degree of MT and occurrence of AMO in the maxillary sinus. However, the location of the AMO is independent of the degree of the MT. There is a greater probability of finding an AMO in the maxillary sinus if the MT in the sinus is more than 3 mm.

The aim of this study was to analyze the oral etiology of patients with odontogenic sinusitis (ODS) and to compare the differences in demographic data, clinical symptoms, extent of sinus involvement, bone penetration of the maxillary sinus floor (MSF) between different etiologies. A retrospective investigation was conducted on 103 patients with ODS recruited from Beijing TongRen Hospital. All enrolled patients underwent sinus CT, nasal endoscopy, and oral examination. A comparison of the patients' clinical symptoms, the extent of involvement of the sinuses, and bone resorption of the MSF according to odontogenic etiologies was conducted. Follow-up was based on symptoms and clinical examination. The most common odontogenic etiologies were endo-periodontal lesions (EPLs, 49.5%), apical periodontitis (AP, 32.0%), and periodontitis (PE, 8.7%). There were statistically significant differences in age ( = 0.002), sex ( = 0.036), inflammation involving the ethmoid sinus ( = 0.037), and bone penetration of the MSF ( < 0.001) between the AP, EPL, and PE groups. There were no significant differences in sinusitis symptoms ( > 0.005) among patients with different odontogenic etiologies. In conclusion, EPL is a neglected oral etiology with a destructive effect on the bone of the MSF, which deserves more attention in diagnosis and treatment.

BACKGROUND/PURPOSE
Because the anatomy and the nature of the bone tissue between the mandible and maxilla are largely different, more site-specific studies are required to improve the healing rate on medication-related osteonecrosis of the jaw (MRONJ). The present study assessed maxillary MRONJ that was treated by surgery to understand its clinical characteristics, and to identify critical factors that influenced outcomes.
MATERIALS AND METHODS
The medical records of 54 patients with maxillary MRONJ who underwent surgery were retrospectively reviewed. Variables related to the prognosis of MRONJ were extracted from the medical records and imaging, and were statistically analyzed. We also evaluated the concomitant maxillary sinusitis (MS) after the surgical treatment of MRONJ, based on CT evaluation and change of symptoms.
RESULTS
The healing rate of surgery for maxillary MRONJ was 85.2%, which suggested that surgical treatment is an effective strategy for treating maxillary MRONJ. Multivariate analysis revealed that postoperative residual necrotic bone was a poor prognosticator for maxillary MRONJ. Among 10 patients who did not obtain healing of MS postoperatively, 8 patients showed an improvement.
CONCLUSION
Our results indicate that surgical treatment is an appropriate strategy for maxillary MRONJ and complete resection of necrotic bone (i.e., extensive surgery) is needed to obtain complete healing of maxillary MRONJ. Concomitant MS tends to be healed or improved clinically in combination with the healing of maxillary MRONJ.

PURPOSE
This study aimed to assess texture analysis (TA) of cone-beam computed tomography (CBCT) images as a quantitative tool for the differential diagnosis of odontogenic and non-odontogenic maxillary sinusitis (OS and NOS, respectively).
MATERIALS AND METHODS
CBCT images of 40 patients diagnosed with OS (N=20) and NOS (N=20) were evaluated. The gray level co-occurrence (GLCM) matrix parameters, and gray level run length matrix texture (GLRLM) parameters were extracted using manually placed regions of interest on lesion images. Seven texture parameters were calculated using GLCM and 4 parameters using GLRLM. The Mann-Whitney test was used for comparisons between the groups, and the Levene test was performed to confirm the homogeneity of variance (α=5%).
RESULTS
The results showed statistically significant differences (<0.05) between the OS and NOS patients regarding 3 TA parameters. NOS patients presented higher values for contrast, while OS patients presented higher values for correlation and inverse difference moment. Greater textural homogeneity was observed in the OS patients than in the NOS patients, with statistically significant differences in standard deviations between the groups for correlation, sum of squares, sum of entropy, and entropy.
CONCLUSION
TA enabled quantitative differentiation between OS and NOS on CBCT images by using the parameters of contrast, correlation, and inverse difference moment.

The aim of the study was to determine the factors influencing the development of recurrence after the surgical treatment of odontogenic maxillary sinusitis in an oral and maxillofacial surgery clinic over a 7-year period. Demographic and anamnesis data, clinical and radiological findings, treatment and outcome were analyzed. A multivariable analysis was performed to find associations between patient age, causative focus, surgical access for sinus revision, multilayer closure with a buccal fat pad, inferior meatal antrostomy (IMA) for temporary sinus drainage and sinusitis recurrence. A total of 164 patients with a mean age of 51.7 years were included. Sinusitis recurrence was observed in nine patients (5.48%) within 6 months after primary surgery. No significant correlation was detected between patient age, causative focus, surgical access for sinus revision, multilayer closure with a buccal fat pad, IMA for sinus drainage and the development of recurrence ( > 0.05). Patients with a history of antiresorptive-related osteonecrosis of the jaw showed a significant tendency toward disease recurrence ( = 0.0375). In conclusion, except for antiresorptive administration, none of the investigated variables were related to a higher risk of sinusitis recurrence. We encourage a combined approach of intraoral removal of the infective focus and sinus drainage via FESS, as well as an individual treatment decision in a multidisciplinary setting with collaboration between dentistry, maxillofacial surgery and otorhinolaryngology to avoid sinusitis recurrence.

Introduction Thermography is a form of radiography that images the skin surface temperature. Thermograms are pictorial representations of thermal maps of the entire body's outer surface. Thermography was applied as an attempt to evaluate its usefulness in the diagnosis of chronic sinusitis (CS). Hence, this study was done to determine the diagnostic value of thermography for patients suffering from CS. Methodology Patients attending the Department of Otorhinolaryngology and Head and Neck Surgery over a two years' duration with symptoms suggestive of CS were included in this diagnostic evaluation study. X-ray paranasal sinuses (PNS) and nose, thermography of head and neck, and computed tomography (CT) of PNS and nose (axial and coronal sections) were performed on them. The thermograms and X-ray sinuses obtained were compared with the computed tomography of PNS findings. Results The study population consisted of 167 patients (75 males and 92 females) and the mean age of the study population was 38.6 years. The sensitivity and specificity of thermography of the head and neck in diagnosing frontal, ethmoidal, maxillary, and sphenoidal sinusitis were 92.59% and 68.58%, 100% and 66.32%, 70.06% and 85.88%, 99.18% and 0%, respectively. Whereas the sensitivity and specificity of the X-ray PNS and nose in diagnosing frontal, ethmoidal, maxillary, and sphenoidal sinusitis were 92.59% and 77.88%, 73.61% and 81.05%, 89.19% and 98.92%, 74.44% and 99.18%, respectively. Conclusion Thermography is better than X-rays in diagnosing frontal and ethmoidal sinusitis and as good as X-ray PNS and nose in diagnosing maxillary sinusitis. Thermography failed to pick up sphenoidal sinusitis. The advantages of thermography are that it is a radiation-free, non-invasive, and cost-effective method for diagnosing CS.

Review
With the spread of oral implant therapy, serious medical complications related to implant surgery are becoming a social problem. Although the number of complications after implant surgery in the edentulous jaw is decreasing in Japan, maxillary-sinus-related complications (MSRCs) have reached the highest number since 2012. It is essential to identify and eliminate possible predisposing risk factors for MSRCs at an early stage to prevent MSRCs. In this review article, we highlight the causal factors of postoperative complications with or without sinus augmentation for the maxillary molar region to achieve optimal treatment outcomes and reduce complications. In particular, we focus on anatomical variations that can cause the impairment of maxillary sinus drainage. Furthermore, we emphasize that the paradigm for personalized medicine for patients with a maxillary edentulous jaw by ENT specialist and dentist cooperation is shifting from the traditional assessment of maxillary sinus pathologies alone to the new assessment of anatomic variations that can cause the impairment of maxillary sinus drainage in addition to maxillary sinus pathologies.

BACKGROUND
Chronic sinusitis is one of the most common chronic diseases involving different age groups. The different etiological factors and difficult diagnostic procedures contribute to misdiagnosis and chronicity of sinusitis. There is no standard treatment for sinusitis. Long term use of corticosteroids and antibiotics may lead to numerous adverse side effects. Laser therapy has been suggested as a non-invasive treatment for sinusitis. It has anti-inflammatory and antibacterial effects. When considering maxillary sinusitis, discharge tends to collect in the sinus base due to its anatomy and altered physiology. To improve penetration of laser into the maxillary sinus, intraoral laser at the vestibule depth of the maxilla may be more effective.
MATERIAL AND SUBJECT
Thirty-four patients with chronic maxillary sinusitis were assigned into two groups. All were assessed before and after treatment. Group A received laser radiation plus standard medical treatment and group B received medical treatment only. The treatment plan was performed in 12 sessions using a Diode laser with a wavelength of 810 nm and 980nm. The SNOT-22 questionnaire and Computed Tomography were used to evaluate patients. A p-value < 0.05 was considered statistically significant.
RESULTS
Both groups showed a significant improvement in symptoms following treatment (p < .001), however, the laser therapy group demonstrated greater improvements for all variables in response to treatment as compared to the traditional treatment group (p < .001).
CONCLUSIONS
Using high intensity intra-oral laser therapy with medical treatment is more effective than using medical treatment only for treatment of chronic maxillary sinusitis.
