Acute Hearing Loss ◽

As the structure of the ear is made of little more than cartilage, a limited blood supply, and a thin layer of skin, trauma in this area can easily manifest from a variety of causes. Some common examples of trauma involve laceration, piercing (intentional or otherwise), infection causing chondritis, blunt trauma causing necrosis, rupture of the tympanic membrane, perforation of the ear drum, and acoustic trauma that may result in hearing disorders such as tinnitus and high-frequency hearing loss. Acute hearing loss shows in two forms: conductive hearing loss and sensorineural hearing loss, the latter of which is caused by damage to the anatomic or neurologic structures of the ear dedicated to hearing. Sensorineural hearing loss generally has a poor prognosis and mandates prompt referral to an otolaryngologist. This review contains 4 figures, 13 tables, and 32 references.

Review of 112 patients with Wegener's granulomatosis showed that 21 (19%) had ear involvement. Conductive deafness, which was present in all 21 patients, was due to serous middle ear fluid, suppurative otitis media with thickening of the tympanic membrane, perforation of the tympanic membrane, or granulation tissue in the middle ear space. Nine patients also had sensorineural hearing loss. Sensorineural hearing loss was improved in five of the nine patients after control of the disease with prednisone and cyclophosphamide.

The Right

In most of the surviving patients after a lightning strike, audiovestibular abnormalities have been reported. The most frequently reported type of abnormalities is a tympanic membrane perforation with hearing loss and external ear canal burn. However a sensor neural hearing loss and mixed type hearing loss can also occur, but these occur rarely. A nineteen-year-old female patient had, after a lightning strike, serious burns on the left ear, behind the ear, and on the chest and neck. She also had in her left ear 108 dB hearing loss with irregular central perforation and in her right ear 52 dB sensorineural hearing loss. There was no hearing loss before the strike. A hearing aid was recommended for the right ear and good care and follow-up were recommended for the left ear. A lightning strike can cause serious audiological damage. Therefore, it is necessary to make a careful audiovestibular evaluation of the patients. Although there exist rarely healed cases from sensorineural hearing loss after lightning strike in literature, in our case hearing loss occurred bilaterally and then it healed unilaterally. This condition is quite rare in literature.

Although rare, ototoxicity from the use of aminoglycoside drops is well recognized. Ototoxicity has not been described with the use of combination aminoglycoside-steroid-antifungal creams or ointments. We present the case of a 60-year-old man with a perforated tympanic membrane who suffered a total hearing loss after the instillation of cream containing triamcinolone, neomycin, gramicidin and nystatin (Tri-Adcortyl™ cream) into his ear canal. On balance, we believe that a number of potentially ototoxic constituents in this cream were responsible. Other possible causes of sensorineural hearing loss and the possible mechanisms of ototoxicity of this cream are discussed. The reasons why such creams may be particularly ototoxic, compared with drops, are also considered. The authors caution against the use of such creams or ointments in the ear if there is any suspicion of a tympanic membrane perforation.

Many studies have been trying to correlate chronic otorrhea, both in children and in adults, with the sensorineural hearing loss in the affected ear, but have been obtaining contradictory results. This loss might be due to the likely toxicity of the bacteria involved, effects of inflammatory cytokines, or constant use of ototoxic antibiotics. All the studies evaluated up to the present date compared the affected ear with the normal contralateral ear. From the digitized archive of otological surgery files of the Department of Otorhinolaryngology, the ears of patients with chronic otorrhea were evaluated visually and compared with the normal contralateral ears. Ears with otorrhea were also compared to ears with dry tympanic perforation of other patients. Ears with suppuration were evaluated for cholesteatoma. The duration of otorrhea was taken into account. The sensorineural hearing threshold was evaluated for the frequencies of 500, 1000, 2000, and 4000 Hz. A total of 98 patients with chronic otorrhea and 60 with dry tympanic membrane perforation were evaluated. From a statistical study, a correlation between sensorineural hearing loss and the chronic otorrhea was observed, in comparison both with contralateral normal ears and with dry perforated ears of other patients. There was no relationship with the duration of suppuration or with whether this was due to cholesteatoma. Sensorineural hearing loss occurs in ears with chronic otorrhea. The duration of otorrhea and the etiology of suppuration did not influence the hearing loss. The great majority of otorrhea cases begin during childhood.

INTRODUCTION Cochlear damage secondary to exposure to acoustic trauma is the consequence of the acoustic energy effects on the hearing cells in Korti's organ. OBJECTIVE The objective was to assess the correlation between the degree of sensorineural hearing loss and the type of audiogram registered in acoustic trauma exposed patients. METHOD We analyzed 262 audiograms of patients exposed to acoustic trauma in correlation to 146 audiograms of patients with cochlear damage and hearing loss not related to acoustic trauma. "A" group consisted of acoustic trauma cases, while "B" group incorporated cases with hearing loss secondary to cochlear ischaemia or degeneration. All audiograms were subdivided with regard to the mean hearing loss into three groups: mild (21-40 dB HL), moderate (41-60 dB HL) and severe (over 60 dB HL) hearing loss. Based on audiogram configuration five types of audiogram were defined: type 1 flat; type 2 hearing threshold slope at 2 kHz, type 3 hearing threshold slope at 4 kHz; type 4 hearing threshold notch at 2 kHz; type 5 notch at 4 kHz. RESULTS Mild hearing loss was recorded in 163 (62.2%) ears in the acoustic trauma group, while in 78 (29.8%) ears we established moderate hearing loss with the maximum threshold shift at frequencies ranging from 4 kHz to 8 kHz. The least frequent was profound hearing loss, obtained in 21 (8%) audiograms in the acoustic trauma group. Characteristic audiogram configurations in the acoustic trauma patient group were: type 1 (N=66; 25.2%), type 2 (N=71; 27.1%), and type 3 (N=68; 25.9%). Audiogram configurations were significanly different in the acoustic trauma group in comparison to the cochlear ischaemia group of patients (p=0.0005). CONCLUSION Cochlear damage concomitant to acoustic trauma could be assessed by the audiogram configuration. Preserved hearing acuity at low and mild frequency range indicates the limited damage to the hearing cells in Korti's organ in the apical cochlear turn.

Background: Chronic squamosal otitis media can occur due to many conditions affecting the middle ear. Most common sign of developing a chronic squamosal otitis media is formation of a retraction pocket in the tympanic membrane leading to further development of a cholesteatoma and if not treated properly, may lead to development of dangerous complication in the affected ear. These etiological factors may also affect the other ear. It is therefore very necessary to assess and diagnose the contralateral ear, so that the disease can be intervened and treated at the right time, to prevent any deterioration in hearing of the contralateral ear.Methods: The prospective study was done in 100 patients with unilateral chronic squamosal otitis media, where the contra lateral ear was examined and assessed for any hearing loss. Results: We found hearing loss in the contra lateral ear ranging from mild conductive hearing loss to sensorineural hearing loss with the maximum patients with mild conductive hearing loss (42%) and lowest in sensorineural hearing loss (1%). Conclusions: In our study, 76 patients were seen with conductive hearing loss. Out of that, 42% patients were seen with mild conductive hearing loss, 30% with moderate conductive hearing loss and 4% with severe conductive hearing loss. 20% patients were seen with normal hearing. 3% patients were seen with mixed hearing loss and only 1% patient was seen with sensorineural hearing loss in contralateral ear.
