A Study of the Maxillary Sinus Volume in Elderly Persons Using Japanese Cadavers

Abstract

Summary: In this paper, using full-body CT images of elderly and advanced elderly Japanese cadavers, we measure maxillary and other paranasal sinus volumes in order to examine the effects of age, sex, presence or absence of maxillary molars, and other factors on changes to maxillary sinus volume. The research subjects consisted of 77 of 95 cadavers donated to the Kanagawa Dental University between 2012 and 2014, which average age was 82.6 ± 10 years (33 were male, average age 79.3 ± 8.3 years, and 44 were female, average age 85.1 ± 11.7 years). Sinus volume was measured from full-body CT images on the horizontal plane and computed using the 3D volume rendering software. The average maxillary sinus volume was 31.3 ± 13.2 cm3 (average value ± one standard deviation; hereafter the same), with values of 32.9 ± 13.2 cm3 (6.7 cm 3 ~ 55.7 cm 3 ) for males and 29.6 ± 12.5 cm 3 (5.5 cm 3 ~ 52.9 cm 3 ) for females. In this report, we studied the effects of aging, sex, and state of remaining molars on changes to paranasal sinus volume in the maxillary sinus. These results give additional information about maxillary sinus volume of Japanese oldest-old peoples.

Assessment of the Relationship between the Maxillary Sinus and the Canine Root tip using Cone Beam Computed Tomography

“…Additionally, in the vertical dimension, the MS-NF was found to be signi cantly higher in the older age group. These ndings con rm those of Belgin et al [25], Takahashi et al [30] and…”

Dimensional changes of the maxillary sinus following tooth extraction in the posterior maxilla with and without socket preservation

“…The preservation of the crestal bone seemed to significantly influence the sinus sagittal circumference changes: 125.95 ± 15.6 and 37.34 ± 6.10 ( P = .0001) for the nongrafted and grafted sites, respectively. Differences in methodologies might account for the great variability in previous reports: Takahashi and colleagues, used full‐body CT images in elderly Japanese cadavers to measure maxillary volumes and to examine the effects of the presence or absence of maxillary molars on maxillary sinus volume change. The volume of the majority of the molar‐retained group was 18.4 ± 5.5 cm 3 while the volume for the no molar remaining group was 14.4 ± 6.8 cm 3 , P < .05.…”

The Effect of the Length and Distribution of Implants for Fixed Prosthetic Reconstructions in the Atrophic Posterior Maxilla: A Finite Element Analysis

“…Pneumatization is the process of maxillary sinus growth that continues throughout life. That said, the degree of pneumatization is one of the main factors leading to limited bone volume [7]. In addition, age, gender, dental status, cause of tooth loss, metabolic diseases, and smoking may significantly reduce the available bone height as well as bone quality in the posterior region [8,9].…”
