Few authors have studied differences in craniofacial morphology of adults with chronic otitis media (COM). We sought to compare the craniofacial measurements of patients with COM with otherwise healthy adults. The study group included 120 adult patients. The control group had 30 men and 30 women without evidence of otitis media; a COM group consisted of 30 men and 30 women with COM. Craniofacial measurements were assessed retrospectively using a two-dimensional reformatted CT method. Multiple linear (bony and cartilaginous auditory tube length, size of the mastoid, height of the jugular bulbus, intercochlear distance, bitemporal distance, distance between pharyngeal orifices, and some cephalometric cranial base distances), angular (auditory tube angle, cranial base angle), and area (axial and sagittal nasopharynx size) measurements were performed. In addition, petrosquamosal (Körner's) septum prevalence and size were evaluated. No statistically significant differences were found regarding craniofacial variables except mastoid size (mastoid depth and length). None of the craniofacial parameters showed significant differences between adults with COM and adults without evidence of otitis media, when age, sex, and race were considered. No statistically significant differences were found when mastoid size was compared with unilateral and bilateral COM. No statistically significant difference was found between mastoid size of the intact side and involved side of the unilateral patients with COM. Patients with unilateral and bilateral COM may be in the same group, genetically or environmentally, as far as mastoid size is concerned. Small mastoid size correlates with COM, but development of clinical disease should be under the control of different factors.
The purpose of this study is to evaluate the relationship between poor oral hygiene and middle ear infections. 59 children between 3-12 age intervals were included in this study. The ears were examined by microscope. The findings were marked according to Kempthorne clinical scale and tympanograms were performed. For data analysis of dental caries, dft and DMFT indexes were used in accordance with WHO (World Health Organization) criteria for oral health surveys. The oral hygiene status was determined by using Simplified Oral Hygiene Index of Greene and Vermillion. The scores of 0-1 were classified as low, and of 2-3 as high oral hygiene index (OHI-S). The low OHI-S was taken as the control group (30 patients). The high OHI-S was taken as the study group (29 patients). The effusion scores, the compliance values and the middle ear pressure values in the two groups were compared. The difference between the effusion score values of the control and study groups was found to be statistically meaningful (p = 0.338, and the χ(2) = 2.167). The compliance values of the control and study groups did not differ meaningfully statistically (p = 0.671). However, there was a statistically meaningful low middle ear pressure (p = 0.044, χ(2) = 4.069) in the control group. Since this finding is expected in the study group, instead of the control group, we did not make an issue of this result. We conclude from these clinical results that there is no statistically meaningful relation between the oral hygiene index and the middle ear.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
