A study of status of contralateral ear in unilateral chronic otitis media in 500 patients

Background: The aim of this study was to examine the contralateral ear clinically, audiologically and radiologically and compare the findings with squamous and mucosal type of chronic otitis media (COM).Methods: A cross sectional study conducted in patients attending ENT Department, Government Medical College, Amritsar between December 2016 to November 2018. The study was conducted in 500 patients of either sex aged between 8 to 60 years with unilateral COM without perforation or history of ear discharge in the contralateral ear. Otoscopy, pure tone audiometry and X-ray mastoid or high-resolution computed tomography temporal bone were done on the patients. The results were recorded and analysed with SPSS software. Results: 82% patients were found to have some abnormalities in the contralateral ear. On otoscopy abnormalities in contralateral ear includes retraction of tympanic membrane, thinning and tympanosclerotic patch, most common abnormality being retraction of tympanic membrane. Radiological analysis of contralateral mastoids showed 39% diploic and 22.8% sclerotic mastoids. Hearing status in the contralateral ear showed 45.6% patient with normal hearing, 48.6% with conductive hearing loss and 5.8% with mixed hearing loss. 40.4% contralateral ears had mild, 12% had moderate and 2% had severe hearing loss.Conclusions: Contralateral ear pathologies were more in those who had squamosal type of COM than who had mucosal type in the diseased ear. The contralateral ear shows unmistakable predilection towards developing COM in the future.

Operative Findings

Introduction Chronic otitis media (COM) is a most common and prevalent disease of the middle ear. COM has been defined as a longstanding inflammatory condition of middle ear and mastoid, associated with perforation of the tympanic membrane. Tympanoplasties are common surgeries performed for chronic otitis media in inactive mucosal type. Any otological surgery may involve a menace/ hazard of hearing loss post operatively. In this study, an attempt was made to correlate, size of tympanic membrane perforation, pure tone audiometry and intra-operative findings in tympanoplasties, results were analysed and conclusion drawn. Materials and Methods Forty patients attending ENT OPD with chronic otitis media (COM), inactive mucosal type, with conductive hearing loss undergoing tympanoplasties who were willing to participate in the study were selected. Ear was examined pre-operatively to assess the size of perforation and then, pure tone audiometry (PTA) was done to assess the type of hearing loss and its severity. During tympanoplasty, middle ear was inspected for ossicular status and any other pathology was noted. Later, the size of tympanic membrane perforation, pure tone audiometry and intra operative findings were correlated with each other and analysed. Result In small and medium sized perforation, PTA and intraoperative findings correlated with each other. Whereas, in large and subtotal perforation, there was no correlation. Conclusion In small and medium sized perforation, middle ear inspection may not be necessary. Whereas, in large and subtotal perforation it is necessary.

Background: After otorrhea and hearing loss, Tinnitus is the most common symptom in patients with chronic otitis media (COM). The aim of this study was to evaluate the improvement of tinnitus in COM patients after tympanoplasty and tympanomastoidectomy surgeries. Materials and Methods: This cross-sectional study was conducted on COM patients suffering from Tinnitus referred to Baqiyatallah hospital, Tehran, Iran undergoing tympanoplasty or tympanomastoidectomy surgeries between March 2013 and August 2014. Tinnitus Handicap Inventory (THI) and Visual Analogue Scale (VAS) questionnaires were filled before and two months after surgery by each patient, and considered subjects were compared with each other. Audiometry test was taken from each patient before and two months after surgery. Audiometry results as well as Air-Bone gap were measured and evaluated prior and after surgery. Data were analyzed using SPSS software by ANOVA, sample t-test and Chi-square tests. Results: Eventually, 26 male and 24 female patients with a mean age of 38.62±11.88 years were enrolled. Air conduction at all frequencies was 49.99±17.37 before and 36.98±22.06 after surgery (P<0.001). Severity of tinnitus was 62.92±30.54 before and 30.54±20.08 after surgery based on THI (P<0.001). Also, it was 7.46±1.66 before and 3.5±2.06 after surgery based on VAS evaluations (P<0.001). Tinnitus severity reduction was significantly associated with the improvement of hearing loss and decrement of air-Bone gap (P<0.001). Tinnitus symptoms such as loudness, annoyance, impact on life and perception of Tinnitus significantly reduced after surgery. Moreover, Tympanomastoidectomy was more effective on the improvement of Tinnitus in comparison with Tympanoplasty (P=0.019).Conclusion: It seems that, both tympanomastoidectomy and tympanoplasty surgeries are effective on the improvement of tinnitus in patients with COM; however, Tympanomastoidectom surgery was shown to be more effective.[GMJ.2016;5(2):63-69]

Contralateral Ear

Introduction: Chronic otitis media is one of the most common ear diseases in developing countries like Nepal and is important cause of the hearing loss. Chronic otitis media is rarely an isolated entity, because the responsible factors for its development in one ear in similar way will impact the contralateral ear, since both ears have a common “nasopharyngeal” drainage. Contralateral ear is defined as asymptomatic ear in cases of unilateral chronic otitis media. Aims: To evaluate the audiological profile of Contralateral ear in post-operative subjects of unilateral otorrhoea. Methods: Patients fulfilling criteria underwent Otoscopic examination, tuning fork test and pure tone audiometry. The findings of contralateral ear like retraction, tympanosclerotic patch (TS patch), thin, dull and atrophied tympanic membrane were noted. The final diagnosis with the type of surgery of diseased ear, as well as status of contralateral ear were entered into the proforma. All the patients were followed till three months in relation to anatomy of Tympanic membrane onotomicroscopy and pure tone audiometry respectively. Results: In postoperative cases of mucosal disease, the cases with abnormality in the contralateral ear reduced from 17 to 10 patients (30.3%) and the normal patients increased from 16 to 23 cases (69.7%). Likewise, in postoperative squamous disease, the cases with abnormality in the contralateral ear reduced from 14 to 11 patients (64.7%) and the normal patients increased from 3 to 6 cases (35.3%). Out of 50 cases, 14 cases (28%) had defective hearing while 36 cases (72%) had normal hearing in the contralateral ear respectively. Conclusion: The high incidence of occurrence of abnormality in contralateral ear indicate that both ears should be regarded as a pair. Unilateral Chronic otitis media should not be taken as a static phenomenon but as a continuous process in the other ear too.

Membrane Perforation

Background: The degree of hearing loss is directly proportional to the size of tympanic membrane (TM) perforation. However, there is dearth of information on correlation between severity of hearing loss and location of perforation on the tympanic membrane. The objective of the study was to determine the hearing level of adolescent and adult patients with tympanic membrane perforation.Methods: A cross sectional study at the ENT Clinic, University of Benin Teaching Hospital (U.B.T.H), Benin City. Consecutive patients with TM perforations were examined with ‘‘Firefly video-otoscope’’, and subsequently had pure tone audiometry. The contralateral intact TMs in individuals with unilateral TM perforation and the ears of students and staff of Institute of Health Technology UBTH were used as control. Data was analyzed using statistical package for social sciences (SPSS) version 20 and Image J software. P≤0.05 was considered statistically significant. Results: Two hundred ears from 148 patients with TM perforation in either or both ears were studied. Conductive hearing loss (CHL) had the highest prevalence; 64.3% and 55.9% in the right and left ears respectively. Slight CHL; 67.5% was more common. However, the severity of hearing loss increased with the size and also varied with the location of TM perforation.Conclusions: The hearing level among adolescent and adult patients with TM perforation showed a significant association with the size and the location of the perforation on the TM.

R Value

Background: Tympanic membrane perforations are common cause of hearing loss. There are very few systematic studies that have evaluated the size and location of a perforation to the degree of hearing loss, this study correlates the size and location of tympanic membrane perforation to the pattern of hearing loss.Methods: The study design was based on cross sectional study. Ninety-six ears of dry tympanic membrane perforation of CSOM mucosal type were selected. Photographs of the tympanic membrane perforations were taken and size measured using the “Image J” software. The area of perforation was compared to hearing loss measured by pure tone audiometry. Results: Ninety-six patients, aged 15-60 years with perforated eardrums were studied. Size of tympanic membrane perforation showed moderate level of correlation with hearing loss (Pearson r value=0.463). The various locations of perforations were: posterior (23 ears with Mean hearing loss 28.6±7.7 dB), anterior (31 ears with Mean hearing loss 26.5±7.8dB), subtotal (42 ears with Mean hearing loss 34.2±8.2 dB).Conclusions: The hearing loss is frequency dependent, with maximum hearing loss at lower frequencies. Irrespective of size of perforation the hearing loss was the least for frequency of 2000Hz. Magnitude of hearing loss increases with increase in size of tympanic membrane perforation. Perforation posterior to handle of malleus resulted in more hearing loss than perforations involving anterior to the handle of malleus.

Background: Chronic suppurative otitis media (CSOM) is the disease of the middle ear cleft, which presents as hearing loss and ear discharge. This study aimed to assess the role of pure tone audiometry (PTA) in analysing the ossicular erosion in mucosal type of CSOM subjects.Methods: The current cross-sectional study was conducted among 60 people with mucosal CSOM. Preoperative hearing was assessed by PTA. The surgeries were done and intra operative ossicular status were recorded. IBM SPSS 20 software was used for the analysis. Student t-test was used to correlate ossicular status and PTA findings. Results: Among 60 subjects, 12 (20%) patients had eroded incus and 53 (88.3%) had normal stapes. The malleus was preserved in all patients. The result of our study showed that an average ABG of 58 dB at 500 Hz, 47 dB at 1 kHz, 41 dB at 2 kHz and 41 dB at 4 kHz in patients with ossicular erosion. ABG for 500 Hz and 1 kHz were statistically significant for eroded incus. ABG for 500 Hz, 1 kHz, 2 kHz and 4 kHz were all statistically significant for eroded stapes.Conclusions: There is a significant difference between the PTA findings at different frequencies between intact and eroded ossicular chain. Pre-operative ABG helps us to assess the status of incus and stapes.

Introduction: Bonebridge® is a novel active bone-anchored hearing implant. The purpose of this study was to evaluate the ease of implantation, the hearing performances, and the patient-reported benefit. Materials and Methods: This is a prospective cross-sectional study of 24 consecutive adult patients implanted for a mixed hearing loss (13 chronic otitis media (COM) and 11 other aetiologies). Twenty-one implants were placed in the retrosigmoid position and 3 in the mastoid. Audiometry, Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire, as well as 5 implant-specific questions (analogue visual scale [AVS] 0–10 score), was administered. Results: Surgery lasted 73 ± 29.7 min on average. No major complication occurred. All patients were users at the last follow-up visit (median: 9-month range: 3–25). The average prosthetic gain was similar in COM and other aetiologies (43 ± 4.8 dB and 50 ± 7.2, respectively, not significant, Wilcoxon test). Bone-conduction thresholds were not deteriorated by surgery (Kruskal-Wallis test, not significant). APHAB scores improved in all categories except aversiveness (global score 45 ± 7.0% in COM and 32 ± 10.2% in others, not significant, and Wilcoxon test). Local pain (AVS: 3.23 ± 3.2, n = 16) and manipulation difficulties (3.1 ± 3.69) were low. The device was considered aesthetic (8.3 ± 2.49). Perfectible autonomy (5.0 ± 2.8) and difficulties wearing the implant during sport or at work (5.1 ± 3.47) were the weakest points. Conclusions: BoneBridge® implant provides reproducible results for the rehabilitation of mixed hearing losses and unilateral hearing loss.

Suppurative Otitis Media

Background: Permanent perforation in the eardrum with persistent drainage from middle ear for more than six weeks is labelled as chronic suppurative otitis media. The major disability of long standing chronic suppurative otitis media presents as disability in hearing thresholds both in young children and adults. The disease has a fewer prevalence in urban regions and mostly is found in the rural population. Aim: To identifying the Prevalence of hearing loss which is sensorineural in patients having middle ear chronic infection (CSOM). Study design & setting: Cross-sectional survey conducted in the department of ENT, Jinnah Hospital Duration/date of the study: 01st February 2020 to 31STJuly 2020 Methods: A Total number of 180 patients were included as a sample in the study. Keeping the level of confidence to 95% and keeping the margin of error to minimum to 5%. These statistics were generated keeping the frequency level of hearing in these patients to minial of 16%. The sampling technique would be non probability type of sampling with a purpose. Results: The results of the study concluded that patients of both sex ranged between first decade and fifth decade. A total of 180 patients had 114 male gender and 66 female gender patients. Patients having chronic middle ear disease were segregated into CSOM (tubo tympanic) with 137 patients and CSOM (attico antral) with 43 patients. The primary indicator of hearing loss in these patients however showed 23 patients having a hearing loss of sensori neural type and 157 patients did not have any sensori neural hearing loss. Conclusions: This research study draws a conclusion that majority cases of chronic middle ear infection is usually the safe type (Tubo tympanic) while a very fewer of these patients of CSOM would have (Attico antral) or dangerous type of CSOM. The major variable of the research, in the form of hearing loss which was sensori neural in patients presenting with CSOM was (12.8%). This percentage is much lower when compared with conductive hearing loss in CSOM. Keywords: Otitis media of chronic type with suppuration, pure tone audiometry, sensory neural hearing loss

Intact Tympanic Membrane

Background: Tympanosclerosis is an irreversible, though not immutable, end result of any unresolved specific or nonspecific inflammatory disease of middle ear characterized by anatomical distortion resulting in functional impairment. The objective of the study was to assess hearing in patients with tympanosclerosis with intact tympanic membrane (TM) and to correlate degree of hearing loss with respect to site of tympanosclerotic patch on TM.Methods: This cross-sectional study was conducted at Bangalore Medical College and Research Institute, Bangalore during study period from November 2016 to May 2018. Thirty patients enrolled for study were subjected to otoendoscopy, pure tone audiometry and tympanometry. Site of tympanosclerotic patch on tympanic membrane and hearing loss were assessed and correlated statistically. Results: Thirty patients (13-males, 17-females), aged 6–73 years (average-39.5 years) who fulfilled inclusion criteria were included. 7 (23.3%) patients had bilaterally affected ears amounting to 37 tympanosclerotic ears. left ear was commonly affected 14 (46.6%). In most patients, tympanosclerosis of tympanic membrane was an incidental finding with patients being otologically asymptomatic. The locations of tympanosclerotic patch on TM were 9 (24.4%) postero-superior, 7 (18.9%) postero-superior and postero-inferior, 7 (18.9%) antero-inferior, 5 (13.5%) postero-inferior, 3 (8.1%) antero-superior, 3 (8.1%) antero-superior and antero-inferior, 2 (5.4%) antero-inferior and postero-inferior and 1 (2.7%) entire pars tensa. Hearing level ranged from 10-46.6 dBHL (normal to moderate) with majority (91.89%) of patients had hearing within 25 dBHL. 43.3% had conductive hearing loss, 2.7% had sensorineural hearing loss and rest had normal hearing. Correlation of site of tympanosclerotic patch on TM with degree of hearing loss was not statistically significant (p=0.058).Conclusions: Variations in the site of tympanosclerotic patch on TM do not affect degree of hearing loss.
