“…In contrast to the findings of Li et al 12 and in agreement with several previous studies, 15,19,32,33,34 this study found that gender does not affect the thickness of the buccofacial maxillary sinus wall. The authors also found that the age of the patients was not a confounding factor affecting the thickness of the buccofacial maxillary sinus wall, again in contrast to the results reported by Li et al 12 and Monje et al 15 Monje et al 15 reported that maxillary sinus wall thickness was directly proportional to patient age, whereas Li et al 12 found an influence of age in the region of the molars.…”

“…14,15 In contrast, in a study of 74 non-embalmed Korean hemifaces, Yang et al 13 reported that the buccofacial wall was thinner in the second molar region than in the first molar region, in agreement with the current findings. A similar observation was recently reported by Danesh-Sani et al 19 Surprisingly, Li et al 12 found that the buccofacial wall gradually became thinner from the region of the second premolar towards the region of the second molar, 5 mm from the floor of the sinus. This observation is consistent with our findings for all 3 ethnic groups in this study.…”

“…In general, this is higher than the values that have been reported for Caucasians and Koreans. 14,16,19 Only 2 other studies reported observing a thickness of more than 2 mm. 12, 18 Li et al 12 reported a thickness of 2.23 mm at the second premolar and a thickness of 2.19 mm at the first molar region 5 mm from the floor of the sinus in Han Chinese.…”

“…However, the vulnerability of the Schneiderian membrane to perforation during this procedure means that it must be managed cautiously while considering the thickness of the buccofacial wall of the maxillary sinus. 11 A few studies have described the topography and thickness of the buccofacial sinus wall, 12,13,14,15,16,17,18,19 but none of these have involved Southeast Asian populations.…”

The implications of different lateral wall thicknesses on surgical access to the maxillary sinus

The objective of this study was to measure the topographic thickness of the lateral wall of the maxillary sinus in selected Asian populations. Measurements were made on the lateral walls of maxillary sinuses recorded using CBCT in a convenient sample of patients attending an Asian teaching hospital. The points of measurement were the intersections between the axes along the apices of the canine, first premolar, and second premolar and along the mesiobuccal and distobuccal apices of the first and second molars and horizontal planes 10 mm, 20 mm, 30 mm and 40 mm beneath the orbital floor. The CBCT images of 109 patients were reviewed. The mean age of the patients was 33.0 (SD 14.8) years. Almost three quarters (71.8%) of the patients were male. The mean bone thickness decreased beginning at the 10-mm level and continuing to 40 mm below the orbital floor. Few canine regions showed encroachment of the maxillary sinus. The thickness of the buccal wall gradually increased from the canine region (where sinus encroachment of the canine region was present) to the first molar region, after which it decreased to the thickness observed at the canine region. The buccal wall of the maxillary sinus became thicker anteroposteriorly, except in the region of the second molar, and thinner superoinferiorly. These changes will affect the approach used to osteotomize the lateral sinus wall for oral surgery and for the sinus lift procedure.

Background The intraosseous artery is a branch of the posterior superior alveolar artery that supplies the lateral wall of the maxillary sinus. The present study seeks to analyze the location of the intraosseous artery and its site of termination. Methods Cone beam computed tomography was used to evaluate 200 patients making up 400 maxillary sinuses. The following criteria were measured: (1) the distance of the lower border of the intraosseous artery to the floor of the sinus, (2) the average length of the artery, (3) the diameter of the artery, (4) the site at which the artery terminates at, and (5) the distance of the artery from the first premolar, second premolar, first molar, second molar, and third molar. Results The intraosseous artery was identified in 336 (84.0%) quadrants. The most common site of termination was at the mesial of the second molar (22%), regardless of dental status and right or left quadrant. Its overall mean diameter was 0.91 ± 0.56 mm, with no difference within the dental status. Its overall mean length was 7.40 ± 3.39 mm, with a statistically significant difference between dentate and edentulous quadrants (P < 0.001). Its overall mean distance from the floor was 6.95 ± 6.49 mm, with no difference within the dental status. All parameters showed no difference between right or left quadrants. Conclusions The chances of encountering the intraosseous artery at the premolar area is <21% during a lateral window sinus floor elevation. The most common (22%) site of termination of the intraosseous artery is at the mesial of the second molar. Understanding of the course, location, and termination of the artery enhances the precision of a clinician when it comes to pre‐operative treatment planning.

BackgroundLateral‐window sinus floor elevation (LSFE) is a reliable procedure to reconstruct the posterior maxilla for implant therapy. This retrospective study aimed to investigate risk factors associated with Schneiderian membrane perforation (SMP) occurrence during LSFE and longitudinal regenerative outcomes following LSFE up to 9 years.MethodsPatients who had LSFE between 2010 and 2019 were included. All demographic and surgical‐related data were retrieved from existing electronic health records. Radiographs were used to evaluate the vertical dimensional changes of ridge and graft materials and the potential anatomic factors of SMP.ResultsA total of 122 LSFE procedures in 99 patients were included in the study. Mean ridge height gain and graft shrinkages were 9.5 ± 3.47 and 1.57 ± 2.85 mm. The influence of the healing period on graft shrinkage showed a positive trend; the longer the healing period, the greater the graft shrinkage (p = 0.09). The pathology in the sinus showed a positive correlation with SMP (p = 0.07). However, other anatomical factors did not negatively impact SMP and subsequent ridge height gain (p > 0.05).ConclusionsWith inherent limitation, the findings with up to 9 years of follow‐up indicate a consistent ridge remodeling lasting for about 3 years after LSFE procedures. SMP or membrane thickening may not significantly affect the ridge gain following LSFE. The healing period had the most significant influence on graft shrinkage, showing that the longer the healing time between LSFE and implant placement, the greater the graft shrinkage.
