“…However, sinus augmentation procedures are not only technique sensitive but are also prone to complications if a thorough preoperative evaluation is not performed. 13 14 15 16 17 In developing any treatment plan for rehabilitation of the edentulous posterior maxilla with implant-supported prostheses, sound knowledge of the anatomy and common variations, patency, and health of the maxillary sinus must be carefully considered. Diagnostic imaging with traditional two-dimensional (2D) radiographic methods using panoramic radiographs and intraoral radiographs plays a crucial role but does not yield three-dimensional (3D) information of the area of interest.…”

PurposeSinus elevation procedures have become a routine and reliable way to gain bone volume in the edentulous maxilla for dental implant placement. Presence of bony septations and pathology in the maxillary sinus often cause complications leading to graft or implant failure or both. The aim of this study was to retrospectively evaluate the prevalence of pathology, direction of the septa, and sinus width measured at 2 mm, 5 mm, and 10 mm from the sinus floor in maxillary sinuses using cone-beam computed tomography (CBCT).Materials and MethodsSeventy-two sinuses from 36 random preoperative CBCT scans referred for implant therapy were retrospectively evaluated for the number, prevalence, and direction of bony septations and presence of pathology. Width of the sinus was also measured at 2 mm, 5 mm, and 10 mm from the sinus floor to account for the amount of bone available for implant placement.ResultsMaxillary sinus septa were found in 59.7%. Presence of a single septum was noted in 20 sinuses (27.7%), followed by two septa in 17 sinuses. The most common direction of the septum was the transverse direction. Retention pseudocyst and mucosal thickening were the most commonly seen abnormality/pathology.ConclusionBased on the high prevalence of septa and sinus pathology in this sample, a preoperative CBCT scan might be helpful in minimizing complications during sinus augmentation procedures for dental implant therapy.

“…Michael et al (11) proposed a score for standardization of variants of pneumatisation using 18 items called Assessment of pneumatisation of paranasal sinuses score (APSS). In our study the pneumatisation identified were that of superior turbinate, crista galli, anterior clinoid process, lateral recess, hard palate , pterygoid plates, and nasal septum.…”

“…Furthermore, volumetric or dimensional analysis of sinus CT tends to be too cumbersome for the large populations that may be necessary to detect small differences [6]. The Assessment of Pneumatization of the Paranasal Sinuses (APPS) score was recently validated for Sinusitis 2016, 1, 92-98 93 evaluating the extent of sinus pneumatization [9,10]. The APPS score evaluates for the presence of nine anatomic variants bilaterally (Table 1, Figure 1), and can be used for clinician assessment of paranasal sinus pneumatization.…”

Abstract:The relationship between paranasal sinus pneumatization and chronic rhinosinusitis (CRS) without cystic fibrosis is not well understood. Previous investigations have confirmed sinus hypoplasia in cystic fibrosis (CF) patients. This study compares paranasal sinus pneumatization of CRS patients to unaffected controls to determine if there is an analogous effect to that seen in CF. 591 sinus computed tomography (CT) scans, comprised of 303 adolescents (age 13-18) and 288 adults (age > 18), were analyzed for Lund-MacKay and Assessment of Pneumatization of the Paranasal Sinuses (APPS) scores. The APPS score is validated for measuring the extent of sinus pneumatization. A diagnosis of CRS and CRS phenotype was determined from the medical record. The mean APPS score for patients with a diagnosis of CRS was 10.61 (n = 111) compared to 9.62 (n = 448) for unaffected controls (p = 0.001). This was significant in adult (p = 0.021) and adolescent subgroups (p = 0.035). Sinus pneumatization did not differ according to CRS phenotype (p = 0.699). This suggests that there is not analogous anatomical sinus variation between CRS and CF, and that the mechanisms underlying sinus hypoplasia in CF may not be universal in patients with other types of sinus inflammation.
