Temporal bone cancer, a relatively rare disease, accounting for less than 0.2% of all tumors of the head and neck and is associated with a poor outcome; often presents in a subtle manner, which may delay diagnosis. It should be suspected in any case of persistent otitis media or otitis externa that fails to improve with adequate treatment. Despite advances in operative technique and postoperative care, long-term survival remains poor). It includes cancers arising from pinna that spreads to the temporal bone, primary tumors of the external auditory canal (EAC), middle ear, mastoid, petrous apex, and metastatic lesions to the temporal bone. Here is a report on a case of temporal bone carcinoma presenting with right otalgia, otorrhea and facial paralysis. The patient was initially diagnosed as mastoiditis and later the clinical impression was revised to temporal bone carcinoma (undifferentiated type), based on the pathologic findings.

Tinnitus is not a disease per se but it is a symptom. It can be either subjective or objective type and the
underlying cause varies such as tumour, infection, vascular abnormality or Meniere’s disease. Foreign body in the external ear is a common presentation especially in children. However, foreign body in the middle ear manifested with only symptom of tinnitus is a rare and unexpected presentation. Foreign body in the middle ear are commonly due to iatrogenic cause such as complication of myringotomy and ventilation tube insertion surgery. There are reported cases of complications of myringotomy and ventilation tube insertion, and they typically presented with the ear infection manifestation, myringosclerosis or permanent perforation of tympanic membrane. Currently, there are only few reported cases in literatures of foreign body in the middle ear following complication of medial migration of ventilation tube into a middle ear with intact tympanic membrane.

Fulltext Chronic discharging ear in a child: are we missing something?

Dutta M, Ghatak S, Biswas G

Med J Malaysia, 2013 Aug;68(4):368-71.

PMID: 24145273

Chronic discharging ear, mostly due to middle or external ear infection, is one of the leading causes for seeking healthcare among the paediatric population in a developing country. However, a long-standing forgotten middle ear foreign body forms a rare cause for such presentation demanding a high index of suspicion from the clinicians. Most of them are iatrogenic or accidental, and are removed by conventional permeatal approach; need for tympanotomy is rarely documented in the recent literature. We report the first case where a large stone was introduced into the middle ear through a pre-existing tympanic membrane perforation by the child himself, and only the second documentation of removal of a middle ear foreign body by tympanotomy in a child.

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.

A patient presenting with an ear polyp is a common finding in otorhinolaryngology practice. The common causes include chronic otitis media and cholesteatoma. We report an adult female patient with a history of acute leukaemia presenting with chronic otitis media symptoms and right ear polyp. She was subsequently diagnosed as relapse of B-cell acute lymphoblastic leukaemia based on histopathological examination. The presentation may be similar to an inflammatory pathology of the middle ear, making it misleading.

Congenital cholesteatoma (CC) is rare clinical condition and It is known as a pearly white mass medial to an intact tympanic membrane. In this case report, we describe a 6-year-old boy who presented with a one year history of left ear discomfort, reduced hearing, followed by ear discharge two months prior to admission. Otoscopic examination revealed a large attic perforation. Radiological investigation showed extensive cholesteatoma in the mastoid, mesotympanum and epitympanum with destruction of the ossicles including the stapes footplate. He underwent radical mastoidectomy in view of extensive cholesteatoma with tympanoplasty type V. In this case report, the classification, treatment and theories related to CC are discussed.

A Longitudinal Analysis of Pressurized Wideband Absorbance Measures in Healthy Young Infants

Wali HA, Mazlan R, Kei J

Ear Hear, 2019 2 27;40(5):1233-1241.

PMID: 30807541 DOI: 10.1097/AUD.0000000000000707

OBJECTIVES: Wideband absorbance (WBA) is an emerging technology to evaluate the conductive pathway (outer and middle ear) in young infants. While a wealth of research has been devoted to measuring WBA at ambient pressure, few studies have investigated the use of pressurized WBA with this population. The purpose of this study was to investigate the effect of age on WBA measured under pressurized conditions in healthy infants from 0 to 6 months of age.

DESIGN: Forty-four full-term healthy neonates (17 males and 27 females) participated in a longitudinal study. The neonates were assessed at 1-month intervals from 0 to 6 months of age using high-frequency tympanometry, acoustic stapedial reflex, distortion product otoacoustic emissions, and pressurized WBA. The values of WBA at tympanometric peak pressure (TPP) and 0 daPa across the frequencies from 0.25 to 8 kHz were analyzed as a function of age.

RESULTS: A linear mixed model analysis, applied to the data, revealed significantly different WBA patterns among the age groups. In general, WBA measured at TPP and 0 daPa decreased at low frequencies (<0.4 kHz) and increased at high frequencies (2 to 5and 8 kHz) with age. Specifically, WBA measured at TPP and 0 daPa in 3- to 6-month-olds was significantly different from that of 0- to 2-month-olds at low (0.25 to 0.31 kHz) and high (2 to 5 and 8 kHz) frequencies. However, there were no significant differences between WBA measured at TPP and 0 daPa for infants from 3 to 6 months of age.

CONCLUSIONS: The present study provided clear evidence of maturation of the outer and middle ear system in healthy infants from birth to 6 months. Therefore, age-specific normative data of pressurized WBA are warranted.

Fulltext Bilateral Carotid Body Tumours

Amran, A.R., Jayaram, G., Kumar, G.

International Medical Journal Malaysia, 2006;5(1):1-6.

MyJurnal

Paragangliomas are slow growing hypervascular tumour arising from neural crest cell derivatives throughout the body. In the head and neck region, the major paraganglial cells are located at the carotid bifurcation (carotid body), along the ganglia of the vagus nerve and along the nerves supplying the middle ear and jugular bulb. Less common locations include the larynx, orbit, nose and the aortic arch. Carotid body tumours are very rare neoplasms constituting less than 0.5% of all tumours. The true nature of the tumour is established at the time of attempted biopsy or surgical resection, sometimes with disastrous consequences. Only a few of the more than 500 cases reported in the literature have been studied and diagnosed preoperatively. These tumours must be considered in the evaluation of any lateral neck mass, even one located far from the carotid bifurcation. We report a case of bilateral carotid body tumours detected using 16-slice MDHCT in a patient who presented with pulsatile neck swelling for two years. This tumour is rarely malignant; however it produces serious problems by its progressive enlargement and impairment of adjacent structures in the neck. The treatment of choice is surgical resection; preferably to excise this lesion when it is small, because large, very vascular tumours are intimately attached to the carotid vessels and make surgical resection more hazardous. Pre-operative embolization can be performed in large tumours, as to facilitates surgery and reduce complication. In most of the cases, there is strong attachment of the tumour to the carotid arteries. When this is the situation, removal of the tumour means complete excision of both great arteries as well, and the mortality rate is 40 to 45 %. When surgical removal is not feasible, radiotherapy may help to control the tumour growth, although the results have not been encouraging. As it is very slow growing tumour with the growth rate of less than 5 mm per year tumours in old patients with significant risk factors for surgical intervention can be managed by observation alone.

Otolaryngol Head Neck Surg, 2008 Jun;138(6):803-4.

PMID: 18503863 DOI: 10.1016/j.otohns.2008.02.020

Cholesterol granuloma (CG) is a histologic description of foreign body giant cell formation toward cholesterol crystals. The majority of temporal bone CG is unilateral and most common in the petrous apex. Middle ear CG is usually the result of underlying ear diseases. Primary middle ear CG is very rare. Most reported CG has not been associated with familial hypercholesterolemia (FH). FH, an autosomal dominant disorder, manifests as high levels of serum cholesterol and low density lipoprotein (LDL) cholesterol. We report a rare case of FH and bilateral aggressive primary middle ear CG. This publication has been approved by the IRB, Hospital Alor Setar.

PMID: 25606279 MyJurnal

Otitis media with effusion (OME) is a condition characterised by a collection of fluid within the middle ear without signs of acute inflammation. It is common in young children, with a bimodal peak at two and five years of age. Eighty percent of children have at least one episode of OME by the age of 10 years. This disease is a common ear problem among children with craniofacial anomalies including cleft palate and Down syndrome (DS).

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.

Primary middle ear tuberculosis mimicking cholesteatoma

Aziz A, Md Daud MK

Malays Fam Physician, 2020;15(1):44-46.

PMID: 32284804

Tuberculous granuloma in the middle ear is an unusual entity. Herein, we report a case with short presentation of otitis media with mastoid abscess but with a CT scan showing widespread bone destruction. The cause was determined to be middle ear tuberculosis. Awareness of this entity is important, as it may cause a delay in referral to an otorhinolaryngology specialist and, subsequently, a delay in initiating treatment. Therefore, it should be considered in the differential diagnosis, especially when the usual treatment fails to produce the desired result.

Hashim ND, Jang SH, Moon IS

Otol Neurotol, 2021 Jan;42(1):e82-e85.

PMID: 33156236 DOI: 10.1097/MAO.0000000000002865

OBJECTIVE: To describe surgical management for transcanal endoscopic ear surgery (TEES) in two patients with aberrant internal carotid artery (ICA) in the middle ear.

PATIENTS: A young girl who complained of pulsatile tinnitus and an elderly man who presented with ear bleeding. Otoendoscopy examination revealed a pulsatile reddish mass protruding through the tympanic membrane in both patients.

INTERVENTIONS: A combination of clinical assessments and imaging supported the diagnosis of aberrant ICA in the middle ear. Transcanal endoscopic reinforcement of the artery was performed; tragal cartilage was used as a shield to strengthen the carotid canal defect.

RESULTS: Assisted by fine endoscopic instruments, the protruding arteries were separated without damage to the surrounding structures and reinforced using tragal cartilage. Both patients' symptoms improved postoperatively; they reported tinnitus relief and hearing improvement.

CONCLUSION: To prevent catastrophic events, diagnosis of aberrant ICA is important before any surgical intervention. With appropriate management, surgical intervention using transcanal endoscopic ear surgery offers a clear view of the surgical field and is an excellent choice for management of aberrant ICA.

The association of allergy and chronic suppurative otitis media: A study in a tropical country

Mohd Khairi MD, Shahrjerdi B, Ramiza RR, Normastura R

Med J Malaysia, 2019 Jun;74(3):205-208.

PMID: 31256174

OBJECTIVE: Chronic suppurative otitis media (CSOM) usually begins as a spontaneous perforation of tympanic membrane due to an acute infection of the middle ear. This study was aimed to evaluate the association between allergy and CSOM.

METHODS: A case-control study was carried out among patients with CSOM (cases) and controls were those with no ear pathology. The presence of CSOM was made through a medical history and otoscopic examination. Allergen testing was done by the skin prick test.

RESULTS: In all 124 subjects were recruited in this study with equal number of the cases and controls. The commonest positive reaction in the skin prick test in both groups was to house dust mites. Among CSOM cases, half (50%) of them had an allergy to Blomia tropicalis and 48.4% to Dermatophagoides while in the control group, 27.4% to Dermatophagoides and 25.8% to B. tropicalis. There were significant associations between CSOM and allergy to B. tropicalis (p=0.005), Dermatophagoides (p=0.016) and Felis domesticus (p=0.040). The prevalence of allergy at 95% confidence interval (95%CI) in CSOM and control groups were demonstrated as 59.7% (95%CI: 47.5, 71.9) and 30.6 % (95%CI: 19.1, 42.1) respectively. There was a significant association between allergy and CSOM (p=0.001).

CONCLUSION: Indoor allergens are the most prevalent in our environment and therefore good control may difficult to achieve. The hypersensitivity states of the subject are likely to have a role in the pathogenesis of CSOM especially in the tropical countries where allergy occurs perennially.

Incidence of middle ear barotrauma in staged versus linear chamber compression during hyperbaric oxygen therapy: a double blinded, randomized controlled trial

Ng AWA, Muller R, Orton J

Undersea Hyperb Med, 2017 8 5;44(2):101-107.

PMID: 28777900

CONTEXT: Middle ear barotrauma (MEB) is common during chamber compression in hyperbaric oxygen therapy. However, little evidence exists on an optimal compression protocol to minimize the incidence and severity of MEB.

OBJECTIVE: To compare the incidence of MEB during hyperbaric oxygen therapy using two different chamber compression protocols.

DESIGN: Double-blinded, randomized controlled trial.

SETTING: Hyperbaric Medicine Unit, The Townsville Hospital, Queensland, Australia, September 2012 to December 2014.

PATIENTS: 100 participants undergoing their first hyperbaric oxygen therapy session.

INTERVENTION: Random assignment to a staged (n=50) or a linear (n=50) compression protocols. Photographs of tympanic membranes were taken pre- and post-treatment and then graded. Middle ear barotrauma was defined as an increase of at least one grade on a modified TEED scale.

RESULTS: The observed MEB incidence under the staged protocol was 48% compared to 62% using the linear protocol (P=0.12, exact one-sided binomial test), and thus the staged protocol did not show a significant improvement in MEB. However, the staged protocol resulted in significantly less severe deteriorations in MEB grades when compared to the linear protocol (P=0.028, exact one-sided Mann-Whitney type test).

CONCLUSION: The use of the assessed staged compression protocol for the first hyperbaric oxygen treatment showed no significant effect on the overall incidence of MEB when compared to the gold standard linear protocol but resulted in a significant improvement in the severity of the experienced MEBs. Further studies are needed to elucidate an optimal compression protocol to minimize middle ear barotrauma.
