The audiological result revealed bilateral conductive hearing loss with an air-bone gap of 9 dB in the right ear and 23 dB in the left ear (Figure 2). Pure tone audiometry, routine preoperative laboratory investigation, and CT temporal bone recommended assessing middle ear and extension of the lesion. Tuning fork test with bilateral Rinne negative and Weber shifted to left ear determined bilateral conductive hearing loss.
AURAL POLYP TRIAL
A second visit, the right ear revealed decrease discharge with shrinkage of aural polyp while the left ear still with wax with the second trial which was again a 'painful wash' that also failed to clean the external canal. Left ear examination was revealed wax with the trial for ear wash after the patient use local softeners but the procedure was 'painful wash'. Suction and packing with a topical cream containing antibiotic and anti-inflammatory were inserted. On examination, the right ear showed purulent, offensive, scanty discharge with aural polyp (Figure 1). There was no pain, facial palsy, or other otorhinolaryngologic manifestations. The patient also complained of right aural discharge which is scanty, offensive, purulent, intermittent, partial improvement on medical treatment in the form of topical and systemic antibiotics, and duration of 4-months. Both conditions with different pathology and inflammatory sequence, but a case with the co-existence of both condition is documented and will be discussed.Ī 17-year-old female presented to me with a history of bilateral diminution of hearing of 4-month duration with gradual onset and slowly progressive course. While in 1893, Schofield introduced the term EACC in the literature. Then in 1874, Wreden presented 12 cases with KO.
Toynbee in 1850 was the first to describe KO with his case report under the name of molluscum contagiosum. The primary EACC incidence is 0.3/ 100,000 population while there is no available data for incidence or prevalence of KO demonstrating the rarity nature. From clinical presentation, radiological investigation, and operative finding I conclude to describe this case with simultaneous external canal cholesteatoma and keratosis obturans.Įxternal auditory canal cholesteatoma, Keratosis obturans, Co-existenceĮxternal auditory canal cholesteatoma (EACC) and keratosis obturans (KO) are diseases that primarily affect the external auditory canal. I report a rare case with co-existence of ipsilateral EACC and contralateral KO. Its association with keratosis obturans (KO) was not documented. Primaryexternal auditory canal cholesteatoma (EACC) is a rare entity. © This is an open-access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.

AURAL POLYP UPDATE
The objectives of our study are: 1) to review the literature about aural polyps and cholesteatoma, 2) to present a diagnosis and treatment update of that uncomfortable and dangerous disease.Īll right reserved.CASE REPORT 7 2 OPEN ACCESS 10.23937/2572-4193.1510104 Clinical and surgical treatment can be undertaken to cure the otitis and eliminate the polypoid mass. Many studies have been undertaken to identify parameters to preview cholesteatomas underlying aural polyps, considering histological, image and clinical criteria. There is significant association between aural polyp and cholesteatoma, and in its presence is necessary a surgical procedure. Little is known about the real nature of the aural polyp, but a lot of diseases can cause or simulate it. Typically it appears in the external auditory canal, where its presence is a sign of chronic infection. de Lima, 5Ana Cláudia Mariushi, 6Carolina H.Volaco, 7Adriana TonelliĪural polyp is a redish soft mass that can arise alone or multiple. 1Luiz Fernando Amarante, 2Anderson Merckle, 3Vinicius Ribas Fonseca, 4Keyla E.
