Thickening of the Schneiderian membrane (SM, mucosa of the maxillary sinus) appears in the paranasal sinus. Information on SM thickening is available for patients receiving sinus lift treatments, which is a risk factor for SM excretory dysfunction. However, more information is needed on the structure of the SM and the relationship between the maxilla sinus and palatine with the alveolar bone and the SM for dental implant treatment in the human maxilla. One hundred twenty-six sides of the maxilla from 71 cadavers were subjected to cone-beam CT (CBCT) analysis and macroscopic and immunohistochemical observations in this study. A thickened SM was mainly observed in the middle region of the basal layer of the maxillary sinus (MS). Strong calcitonin gene-related peptide (CGRP)-positive reactions were observed in the alveolar bone, oral mucosa, mucosa of the maxillary sinus, and trigeminal ganglion (TG) cells in dentulous samples compared with edentulous samples. TG cells play important roles in delivering CGRP through axons to the mucosal gland and in regulating the maxilla-related thickening of the SM. These data could help determine CGRP functions in the mucosal gland and bone formation between dentulous and edentulous samples and indicate that CGRP may pass from the TG to the maxillary sinus glands.

Abstract OBJECTIVES. The purpose of this article is to highlight some terms which have been ingrained in the rhinosinusology literature. MATERIAL AND METHODS. It regards the term “accessory ostium” and the term “septal deviation”. The well-known and deeply ingrained term “accessory ostium” has been widely used for decades, but essentially it is absolutely incorrect. “Septal deviation” is an inadequate term for the changes of the nasal septum form. RESULTS. From the linguistic point of view, “accessory” means something (or someone) which (or who) helps someone or gives support (to something or someone) in some process. We recommend the use of the term “defect of the fontanel” instead of “accessory ostium”. The use of the term “septal deformity” (from Latin: de forma, meaning the change in the shape) is etymologically much more appropriate. Septal deformities appear in man in several, well defined shapes and, therefore, can be correctly classified. The classification contributes to the further scientific conversations regarding the clinical issues connected to the changes of the nasal septum form. CONCLUSION. The usual term “accessory ostium” suggests almost a normal finding on the lateral nasal wall, but, on the contrary, it clearly signalizes that the respective maxillary sinus is chronically inflamed. The usual term “septal deviation” is not at all specific and only suggests that something is wrong with the position of the nasal septum. It does not at all imply any of the six well known types of septal deformities in man.

Objectives: Sinus floor elevation and augmentation surgery is widely used as a reliable procedure to increase insufficient bone height in the posterior maxillary area. The purpose of the present clinical study was to determine the associations between periodontal bone loss (PBL), maxillary sinus lateral bone wall thickness, age, and gender using cone-beam computerized tomography (CBCT). Materials and Methods: The current retrospective study consists of 716 maxillary sinus CBCT images of 358 patients. The CBCT scans were assessed to detect the relationship between lateral wall thickness and PBL. ANOVA and Student t test analysis were used to determine the influence of PBL on sinus lateral wall thickness. Results: Sinus lateral wall thickness was significantly associated with PBL (p < 0.05) at 3, 13, and 15 mm height. There was no significant association between lateral wall thickness and gender (p > 0.05). However, there was a significant association between lateral wall thickness at 3 and 13 mm and age (p < 0.05). There were significant associations between PBL and age (p < 0.001), and PBL and gender (p < 0.05). Conclusions: PBL might have an association with maxillary sinus lateral bone wall thickness. Further studies are needed to confirm this possible relationship.
