Role of impacted cerumen in hearing loss

Subha ST, Raman R

Ear Nose Throat J, 2006 Oct;85(10):650, 652-3.

PMID: 17124935

We performed a study to determine if cerumen in the ear canal causes significant hearing loss and to ascertain if there is any correlation between the amount of cerumen and the degree of hearing loss. Our study was conducted on 109 ears in 80 patients. The results indicated that impacted cerumen does cause a significant degree of conductive hearing loss. We found no significant correlation between the length of the cerumen plug and the severity of hearing loss. Nor did we find any significant correlation between the presence of impacted cerumen and variables such as age, sex, ethnicity, or affected side.

Acta Otolaryngol, 1991;111(3):536-41.

PMID: 1887780 DOI: 10.3109/00016489109138380

Two hundred Malaysian patients representing 227 ears with previously untreated cholesteatoma disease were analysed retrospectively in terms of i) type of disease, i.e. primary acquired attic defect or posterior superior retraction pocket and secondary acquired type cholesteatoma; ii) positive history of previous middle ear effusion, atelectasis or grommet insertion; and iii) likelihood of complications as initial presenting feature. The high 47.1% incidence of secondary acquired cholesteatoma disease in our patients contrasts with the predominance of primary acquired cholesteatoma in the Caucasian patient. Correlation of these two disease types with a positive history showed a significant positive association between the primary acquired group and a positive history; and conversely a significant negative association for the secondary acquired type. This supports a role for the retraction theory in primary acquired cholesteatoma but negates this theory in secondary acquired cholesteatoma. Secondary acquired cholesteatoma had a significantly higher (35.5%) complication rate against 15.8% in the primary acquired type (p = 0.001). This fact together with a 47.1% incidence of secondary acquired disease, low otolaryngologist population ratio and patient attitudes to disease account for the high total complication rate of 27.3%.

MyJurnal

The reconstruction of the upper eyelid with medial canthal involvement post extensive removal of malignant tumour remains a challenge. Proper eyelid reconstruction is necessary to reestablish anatomic integrity, restoration of its functions and to maintain the best cosmetic appearance. These case reports illustrate an alternative reconstructive technique for large upper eyelid full thickness defect with medial canthal involvement. Two cases of upper eyelid tumours involving medial canthal region underwent staged reconstruction by glabellar flap advancement and reconstruction of the posterior lamellar with autologous graft using buccal mucosa and ear cartilage. The posterior lamellar graft and flap survived without any complication except for mild eyelid margin notching in one of the two cases. The staged reconstruction with glabellar flap advancement provides adequate defect coverage, excellent blood supply, maintains eyebrow contour and function of the eyelid. The flap also perfectly matches the surrounding tissue with minimal donor site morbidity.

Fulltext Congenital cholesteatoma: Different clinical presentation in two cases

Abdul Jalil S, Md Daud MK

Malays Fam Physician, 2016;11(2-3):30-32.

PMID: 28461856

INTRODUCTION: Congenital cholesteatoma (CC) of the middle ear is a rare entity that may be undiagnosed for years. The lesion can grow undetected until it produces symptoms such as reduced hearing or otalgia.

METHOD: Case report.

RESULTS: We report two cases of young ladies with CC who presented with different otological symptoms. The first case complained of recurrent unilateral ear pain while the second case presented with unilateral reduced hearing. Examination of both cases revealed a whitish mass seen behind an intact tympanic membrane. Both cases underwent surgery and histopathological examinations; findings were consistent with cholesteatoma.

CONCLUSION: There are varieties of clinical presentations of CC and the diagnosis is based on clinical findings.

Malaysian Journal of Medicine and Health Sciences, 2014;10(1):7-11.

MyJurnal

The effect of loud noise to the army personnel is often identified when hearing loss had already developed. Acoustic trauma during shooting training can also lead to acute changes in the ear which is shown on otoscopic examination. This study was undertaken to determine the effectiveness of hearing protective device (earplug) on the prevalence of external ear changes amongst military personnel during shooting. This is a prospective cross sectional study that was conducted among 76 military personnel, who were divided into two groups: those with and without earplugs during shooting. Each participant underwent 3 otoscopic examinations: (a) pre-shooting, (b) immediate post-shooting (within 48 hours) and (c) 2 weeks after shooting. A total of 78 army personnel who were scheduled to undergo shooting training were otoscopically examined. Eighty three percent of them did not wear earplugs before. The percentage of inflammation of external auditory canal and tympanic membrane dullness increased tremendously among subjects from non–earplug group less than 48 hours post-shooting. Assessment after 2 weeks showed improvement in around 30% of the subjects. Loud noise has become an occupational hazard not only to the inner ear but it also predisposes the external and middle ear structures to some form of injury. Although improvement is seen after some period, a protective device such as an earplug should be recommended and the usage should be reinforced among the army personnel involved in shooting.

Pressurized Wideband Absorbance Findings in Healthy Neonates: A Preliminary Study

Wali HA, Mazlan R, Kei J

J Speech Lang Hear Res, 2017 10 17;60(10):2965-2973.

PMID: 28975265 DOI: 10.1044/2017_JSLHR-H-17-0120

Purpose: The present study aimed to establish normative data for wideband absorbance (WBA) measured at tympanometric peak pressure (TPP) and 0 daPa and to assess the test-retest reliability of both measurements in healthy neonates.

Method: Participants of this cross-sectional study included 99 full-term neonates (165 ears) with mean chronological age of 46.7 hrs (SD = 26.3 hrs). Of the 99 neonates, 58 were Malay, 28 were Indian, and 13 were Chinese. The neonates who passed high-frequency (1 kHz) tympanometry, acoustic stapedial reflex, and distortion product otoacoustic emission screening tests were assessed using a pressurized WBA test (wideband tympanometry). To reduce the number of measurement points, the WBA responses were averaged to 16 one-third octave frequency bands from 0.25 to 8 kHz. A mixed-model analysis of variance was applied to the data to investigate the effects of frequency, ear, gender, and ethnicity on WBA. The analysis of variance was also used to compare between WBA measured at TPP and 0 daPa. An interclass correlation coefficient test was applied at each of the 16 frequency bands to measure the test-retest reliability of WBA at TPP and 0 daPa.

Results: Both WBA measurements at TPP and 0 daPa exhibited a multipeaked pattern with 2 maxima at 1.25-1.6 kHz and 6.3 kHz and 2 minima at 0.5 and 4 kHz. The mean WBA measured at TPP was significantly higher than that measured at 0 daPa at 0.25, 0.4, 0.5, 1.25, and 1.6 kHz only. A normative data set was developed for absorbance at TPP and at 0 daPa. There was no significant effect of ethnicity, gender, and ear on both measurements of WBA. The test-retest reliability of WBA at TPP and 0 daPa was high with the interclass correlation coefficient ranging from 0.77 to 0.97 across the frequencies.

Conclusions: Normative data of WBA measured at TPP and 0 daPa for neonates were provided in the present study. Although WBA at TPP was slightly higher than the WBA measured at 0 daPa at some frequencies below 2 kHz, the WBA patterns of the 2 measurements were nearly identical. Moreover, the test-retest reliability of both WBA measurements was high.

Singapore Med J, 1991 Feb;32(1):90-1.

PMID: 2017717

The case of an elderly Chinese male opium addict with cauliflower ears is discussed. He had no history of contact sports that could have led to auricular trauma resulting in deformed ears. Besides cauliflower ears, he had features of chronic bronchitis. The association between opium addiction and cauliflower ears was first described way back in 1932. It was attributed to the prolonged opium induced sleep on hard surface subjecting the ears to repeated pressure and trauma. With the changing pattern of drug abuse, opium abuse related cauliflower ears will become a vanishing sign.

Int J Environ Res Public Health, 2023 Feb 08;20(4).

PMID: 36833630 DOI: 10.3390/ijerph20042934

This systematic literature review (SLR) aims to determine the factors influencing the use of hearing protection devices (HPDs) among industrial workers. This study was guided by the PRISMA Statement (Preferred Reporting Items for Systematic reviews and Meta-Analyses) review method, and four databases comprising Scopus, Science Direct, PubMed, Wiley Online Library, and Google Scholar were employed. A total of 196 articles were identified, and 28 studies on the factors associated with HPD use among industrial workers from 2006 to 2021 met the inclusion criteria. Resultantly, five main themes emerged from this review: sociodemographic (29%), interpersonal influences (18%), situational influences (18%), cognitive-perceptual (29%), and health-promoting behavior (6%) associated with HPD use among industrial workers. A total of 17 sub-themes were identified, including age, gender, educational level, noise level, working experience, social models, interpersonal support, social norms, safety climate, training, organizational support, perceived barrier, perceived susceptibility, perceived severity, perceived benefit, self-efficacy, and cues to action. The significant factors influencing workers to use HPDs are sociodemographic, interpersonal influences, situational influences, and health-promoting behavior. Future studies should focus on the cues to action toward human behavior influencing the use of HPDs, workers' health status, and comorbidities of hearing loss. Therefore, this systematic study gives valuable reference resources for up-and-coming researchers as well as new knowledge to expert professionals and academics in various industries.

Epithelial migration on the external ear canal wall in normal and pathologic ears

Revadi G, Prepageran N, Raman R, Sharizal TA

Otol Neurotol, 2011 Apr;32(3):504-7.

PMID: 21307812 DOI: 10.1097/MAO.0b013e31820d97e2

HYPOTHESIS: Epithelial migration on the external auditory canal (EAC) wall is abnormal in ears with keratosis obturans (KO).
BACKGROUND: Earlier studies of epithelial migration have focused on the tympanic membrane with scattered information available for epithelial migration on canal walls. This study was undertaken to observe the epithelial migration on the EAC wall in normal ears and in ears with KO.
METHODS: Twenty-five subjects with normal ears and 4 with KO were recruited for the study. Colored ink dots were placed around the tympanic annulus at the 12, 3, 6, and 9 o'clock positions. Migration patterns and the rate of travel of these ink dots were examined and photographed until the ink dots reached the bony cartilaginous junction.
RESULTS: Fifteen healthy subjects and 1 with bilateral KO completed the study. The ink dots migrated laterally, with a rate of migration in normal ears between 42 and 205 μm/d. The mean rates for each quadrant, measured clockwise from the 12 o'clock position, were 104.93, 89.80, 72.67, and 109.93 μm/d, respectively. The pathologic ears exhibited a rate between 88 and 140 μm/d, and at approximately 4 to 12 weeks after ink application, areas of abnormal desquamation were apparent at the inferior quadrant, leading to a halt in the migration of the ink dot once it reached these sites.
CONCLUSION: Epithelial migration occurred in an almost linear pattern in all quadrants, but the speed of migration was relatively slower in the anterior and inferior quadrants of a normal EAC. In the single KO patient, there were areas of normal migration and areas of abnormal keratin resurfacing at the inferior quadrant, which interfered with the migration of ink dots.

PMID: 11082788

The incidence of ear lobe crease (ELC) was studied in 1576 healthy Malay subjects (566 males and 1010 females), randomly selected from the residents of Kota Bharu, Malaysia. ELC was present in 31.1% of males and in 3.6% of females; this difference in incidence between the two sexes is statistically significant (p > 0.05). In males the incidence of Type I crease was highest (10.1%) while that of Type III crease was lowest (2.3%). In females Type II crease showed the highest incidence (1.9%) and Type III the lowest. The incidence of bilateral presence of all three types of ELC showed an age-related increase in males. The ELC often starts unilaterally and later develops bilaterally and earlier in males than in females.

Osteomas occur in all parts of the temporal bone, including the mastoid, squamous, middle
ear, styloid process, internal auditory canal and external auditory canal (EAC). The EAC has
been reported to be the most common site, followed by the mastoid and squamous parts.
Diagnosis is made based on history, clinical examination and radiological findings. Computed
tomography reveals a pedunculated hyperdense mass that usually arises from the
tympanosquamous suture. Surgical removal of EAC osteomas can be achieved using the
endaural or postauricular approaches. It can be performed with a drill or osteotome, either
endoscopically or by using microscopy. This report presents two patients with EAC osteomas
who underwent excision under microscopy using the endaural approach. Surgery is the gold
standard treatment, while close observation may be considered in asymptomatic patients.
