Maxillary Sinus Septa: Prevalence and Association With Gender and Location in the Maxilla Among Adults in Sana'a City, Yemen

Abstract

Background and aims: Maxillary sinus septa are partitions of cortical bone dividing the sinus into multiple compartments. Their presence and dimension are of relevance to periodontitis, oral and maxillofacial surgeons as well as otolaryngologists. The aim of this study was to determine the prevalence and association of maxillary sinus septum with gender and location in maxilla among adults in Sana’a city, Yemen.
 Methods: This is a retrospective study carried out on 633 patient orthopantomograms (OPGs) which had visible maxillary sinus without pathological or developmental changes from the first of March 2021 to the end of February 2022 at the Department of Oral and Maxillo-Facial Surgery, Faculty of Dentistry, Sana’a University and private clinics in Sana’a city. Descriptive statistics of the continuous variable (age) was summarized as mean and standard deviation while the categorical variables were summarized as frequencies and percentages and presented as tables. Bivariate analysis was performed to test for association between the dependent variables (maxillary sinus septum presence, presentation and position) and independent variables (gender and location).
 Results: The mean age of the patients was 29.59 years, range from 16 -56 years, and females 380 (60.0%). Of 259 (40.9%) maxillary sinus septum identified, 206 (79.5 %%) were from females. Majority 180 (69.5%) were unilateral, while 79 (30.5%) were bilateral. Occurrence of unilateral maxillary sinus septum was higher in males 104 (41.1%) with OR=2.8, 95% CI=1.9-3.98, p<0.0001; than females (20%), while bilateral septum occurs roughly in equal rates in both gender (11.86 VS 12.89%). 
 Conclusion: This study has shown a significant proportion of maxillary sinus septum among patients with visible orthopantomogram without pathology in Sana’a, Yemen, with the highest proportion being females. There is therefore the need for the occurrence and presentation of maxillary sinus septum in this study to serve as a baseline data in the treatment of dental implant and surgical procedures in Sana’a, Yemen.

 UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.

Maksilller Sinus Septasının Yeri, Yüksekliği ve Prevelansı: Panoramik Radyo-grafi ve Konik Işınlı Bilgisayarlı Tomografi Karşılaştırması

“…Therefore, these differences in findings highlight the importance of considering the specific population being studied and the sample size when interpreting the prevalence and dimensions of septa within the maxillary sinuses. Alhadi et al (25) evaluated 633 panoramic images. They observed septa in 180 cases (69.5%) unilaterally and in 79 cases (30.5%) bilaterally.…”
