Contralateral Ear in Chronic Otitis Media: A Histologic Study (original) (raw)
Contralateral ear findings in chronic otitis media
SiSli Etfal Hastanesi Tip Bulteni / The Medical Bulletin of Sisli Hospital, 2017
C hronic otitis media (COM) is a major health problem, especially in developing and underdeveloped countries. The chronic nature of the disease can lead to repeated hospital visits and increased financial burden, hearing loss, and related social problems concerning ear discharge, education/learning difficulties, and especially in untreated cases, life-threatening complications. COM is a disease that can affect both ears. Therefore, it is important to know the findings of the contralateral ears other than the affected ears to determine the changes in the tympanic membrane before the onset and during COM in this ear. For this purpose, the data of the patients who were operated on for COM between 2014 and 2017 were reviewed retrospectively. Otoscopic findings, audiologic examinations, and tomography images of the ipsilateral and contralateral ears of the patients were evaluated. Methods In this study, a total of 295 (131 females/164 males) patients who had been operated for the management of COM at the Objectives: Chronic otitis media (COM) reveals a spectrum of otoscopic findings, and both ears may be affected to a different degree. The analysis of contralateral ear in patients with COM is important to detect the early signs of the disease. This may enable the follow-up and treatment of abnormalities in contralateral ear without delay. Therefore, in this study, we aimed to investigate the otoscopic and audiologic findings of contralateral ears of patients with COM. Methods: The institutional data of patients who underwent surgical treatment between 2014 and 2017 due to COM were reviewed. Suppurative ears with cholesteatoma, polyps, and otorrhea refractory to medical treatment and ears with dry middle ear mucosa, with otorrhea responsive to medical treatment, and without cholesteatoma were divided into two groups (Group 1 and Group 2, respectively). All patients were examined with regard to the presence of perforation, retraction, myringosclerosis, atrophy, and audiological results before the groups were compared. Results: Approximately 50% of contralateral ears of patients with COM showed abnormalities at an otoscopic examination in both groups. Tympanic membrane retraction in Group 1 was greater than in Group 2, and the difference was statistically significant (p<0.05). Both the mean air and bone conduction thresholds of the contralateral ears in Group 1 were also found to be elevated when compared with Group 2, and the differences were statistically significant (p<0.05). Conclusion: COM may be seen bilaterally due to the same predisposing factors affecting the ears. Therefore, detection, followup, and early treatment of abnormalities of contralateral ear associated with otitis media have clinical importance in the prevention or delaying progression of these abnormalities to COM.
Status Of Contralateral Ear In Patients With Chronic Otitis Media
The Internet Journal of Health
Objective: To study the status of contralateral ear in patients with chronic otitis media.Materials and Methods: This is a prospective study in patients attending GMS Memorial Academy of ENT and Head and Neck Studies, Kathmandu between July 2008 and December 2008. There were 750 patients diagnosed as having chronic otitis media (COM) squamous and mucosal type. Otoscopy was performed in all patients in such ears and the status of contralateral ear was noted. Statistical analysis was performed by simple manual analysis using frequency and percentage. Results: Out of 750 patients, 64.4% were male and 35.6% were female. Regarding types of COM, 36.0% were squamous type. In 68.4% of the patient, the contralateral ear was found to have some form of abnormalities. In mucosal type of COM, 62.9% patients had abnormal contralateral ear while in squamous type, 71.4% patients had abnormal contralateral ear. The most common findings on contralateral ear in both group of patients was retraction of the tympanic membrane.Conclusion: Patients with COM in one ear are more likely to develop some degree of disease in the contralateral ear. The squamous type of chronic otitis media had a greater chance of contralateral ear involvement.
Chronic otitis media: histopathological changes: a post mortem study on temporal bones
European review for medical and pharmacological sciences
The temporal bones of 4 deceased individuals, with concomitant chronic otitis media are studied. The various histopathological changes in the middle ear cleft are examined: suppuration, polyps, granulation tissue. The possibilities of spontaneous healing of a perforated TM and the indications of surgical treatment are discussed.

Cochlear pathology in human temporal bones with otitis media
ACTA OTOLARYNGOLOGICA, 2010
Conclusion-Middle and inner ear interactions in otitis media can lead to cochlear pathology. More severe pathological changes observed in the basal turn of the cochlea are consistent with prevalence of sensorineural hearing loss at higher frequencies in patients with otitis media.
Volumetric Changes in the Bony External Auditory Canal in Unilateral Chronic Otitis Media
Journal of audiology & otology, 2016
Pneumatization of air cells in the mastoid bone is decreased in chronic otitis media (COM). A decrease in the size of the external auditory canal (EAC) is also found frequently in patients with COM, but this has been little studied. We compared the size of affected bony EACs and the contralateral side in patients with single-side COM using high-resolution computed tomography. In total, 99 patients with single-side COM were included. Four indicators related to the size of the bony EAC and IAC were measured using high-resolution computed tomography: the axial and coronal lengths of the tympanic membrane, the length of the isthmus, and the area of the bony ear canal. We also compared both internal auditory canals as negative controls. These assessments were made by radiologists who were blinded to the objective of this study. In patients with single-side COM, the axial length of the tympanic membrane was significantly shorter than normal, and the volume of the EAC was also significantl...

As the disease process does not affect both the ears simultaneously in all the cases, it is possible to identify in early stages of the disease process and arrest further progression by timely intervention. Hence, we aim to study the anatomical and functional changes in contralateral ear (CLE) in pts with unilateral CSOM. prospective observational study, of 75 patients attending the OPD of JLN hospital and research center, Bhilai, with unilateral CSOM, with intact TM in CLE were evaluated by otoscope, PTA, Impedance audiometry and CT temporal bone. Above observations were recorded and analyzed. 44% in our study showed abnormal TM, most common was TM retraction, seen in 22.66%. PTA showed mixed hearing loss in 5.33% and normal hearing in 66.66%. Impedance audiometry had A type graph in 82.66%, As type in 10.66%. Compliance was normal in 82.66% and decreased in 10.66%. Pressure was normal in 97.33% and was decreased in 2.66%. Normal, well pneumatized air cells in HRCT temporal bone se...

Whether the dimension of the osseous external auditory canal (OEAC) is related to chronic otitis media (COM) remains an important but unresolved issue. In the literature, routine canaloplasty has been suggested to help elucidate this problem. In this study, we intended to investigate the relationship between the diameter or shape of OEAC and COM. We retrospectively reviewed the high-resolution computed tomography (HRCT) images of the temporal bones of 62 patients with unilateral COM who underwent tympanoplasty from January 1, 2011, to December 31, 2013. For comparison, the HRCT images of another 62 patients with normal ears were collected to be the control group. The shape of OEAC was categorized into 5 groups according to Mahboubi’s classification, and the dimension of each patient’s OEAC was measured at 2 defined sections (annular section and isthmus/midcanal section). The most prevalent shape of OEAC for the lesion sides of the ears was cylindrical, followed by conical, and hourg...
