“…In the studies, [13,28] which accounted for 375 subjects (2.89% of the total sample), the sex of the participants was not specified. The remaining 24 studies [29–51] included both males and females in their samples. These studies had in total 5802 men, representing 44.73% of the total sample, and 6792 women, representing 52.37% of the total sample (Tables 1 and 2).…”

Objective: The objective of this review is to investigate and analyze the anatomical variations present in the maxillary sinus (MS), through the examination of the prevalence of these variations, as well as the corresponding prevalence of clinically significant pathologies and complications associated with them. Methods: The search process was carried out in the following databases; MEDLINE, SCIELO, WOS, CINHAL, SCOPUS, and GOOGLE SCHOLAR, using as search terms; “Maxillary bone,” “Maxillary sinus,” “Paranasal sinus,” “Anatomical variations,” “Sinusitis” and “Clinical anatomy.” Results: A total of 26 articles and 12969 samples were included, from which 12,594 subjects had their sex recorded giving a total of 5802 males and 6792 females. The variants reported by the included were Haller cells, Concha Bullosa, Number of septa, Hypoplastic sinus, Agger Nasi, Thickening of the MS mucosa, Deviation of the nasal septum, Accessory ostium, and Onodi cells. Among the mentioned, the ones that presented the greatest number of studies (between 8 and 10 studies included) were: the Haller Cells, the Concha Bullosa, and the Number of septa, where prevalence was 0.30, 0.36, 0.39 respectively. These variations can lead to sinusitis, cause some types of tumors, or affect neighboring structures that could be compromised by this variation. Conclusion: As a result, it is certainly complex to distinguish the presence of anatomical variations from pathological abnormalities. Therefore, knowledge of the different variations and their clinical relationships could be a useful asset for clinicians dedicated to this region.

“…The maxillary sinus is an important anatomical structure in maxillofacial surgery. Since previous studies have mainly focused on the condition of the maxillary sinus floor with respect to maxillary implants, there have been few reports on the effect of the presence or absence of a deviated nasal septum, polyp formation in the maxillary sinus, the presence or absence of a septum, the influence of bone head height on maxillary sinus volume [ 11 , 15 , 16 ], or the susceptibility to maxillary sinusitis due to a deviated nasal septum [ 7 ]. However, the maxillary sinus’ pathological state, shape, and size significantly affect the indications, difficulty, and rate of complications of maxillary sinus augmentation.…”

“…Another study reported that the maxillary sinus volume (MSV) differs between individuals with and without maxillary sinusitis [ 10 ]. Furthermore, the relationship between sinus volume and polyp formation and chronic rhinosinusitis has also been reported, suggesting a strong association between sinus volume and maxillary sinus lesions and OMC [ 11 ]. Thus, assessing the anatomical characteristics of the maxillary sinus that function as complicating factors in maxillary sinus augmentation is considered absolutely crucial.…”

Effects of missing teeth and nasal septal deviation on maxillary sinus volume: a pilot study

Purpose Tooth extraction and the projection of the tooth roots into the maxillary sinus are reported to greatly reduce the bone height from the alveolar ridge to the maxillary sinus floor, while missing teeth are reported to lead to the expansion of the maxillary sinus, all of which are important considerations during dental implant treatment for the maxillary molar region. Therefore, assessing the anatomical characteristics of the maxillary sinus acting as complicating factors is crucial before sinus augmentation. We conducted a three-dimensional examination of the effects of missing teeth and nasal septal deviation (NSD) on maxillary sinus volume (MSV). Methods We selected participants with two or more missing teeth from patients who underwent maxillary sinus augmentation for a unilateral free-end saddle between April 2019 and December 2020. We calculated the MSV and NSD using cone-beam computed tomography (CBCT). We compared the relationships of the presence/absence of teeth and NSD with MSV bilaterally in each patient using the Wilcoxon t-test. p-values < 0.05 denoted statistical significance. Results This study included 30 patients (30 sinuses; 12 men, 18 women). The average patient age was 58.2 ± 10.2 years (men, 60.4 ± 3.7 years; women, 59.2 ± 4.5 years; range, 40–77 years). The mean number of missing teeth was 2.98 ± 1.01: 13 patients had two missing teeth and 17 had three or more missing teeth. Nine patients (30%) had NSD. The mean MSV on the ipsilateral and contralateral sides of the NSD was 21.50 ± 3.84 cm3 and 22.10 ± 3.56 cm3, respectively; thus, NSD did not affect MSV (p = 0.150). The mean MSV on the edentulous and non-edentulous sides was 21.58 ± 3.89 cm3 and 21.77 ± 4.30 cm3, respectively; thus, the MSV was significantly smaller on the edentulous side (p = 0.00036). Conclusion Although this study was a limited preoperative study, three-dimensional measurement of the maxillary sinus with CBCT in partially edentulous patients revealed that missing teeth lead to substantial reductions in MSV, while NSD was not associated with MSV.

“…Factors associated with ACP, such as increased maxillary volume and high prevalence of anatomical variation around the natural ostium further suggest that anatomical or mechanical abnormalities are the primary etiology in the disease pathogenesis. 13 However, consistent results regarding the treatment outcome of ACP are that complete resection of polyp attachment reduces disease recurrence. 11 14 This implies that the pathogenesis of the disease might be somewhat simplified.…”
