Correlation among external auditory canal anomaly, temporal bone malformation, and hearing levels in patients with microtia

June 20, 2017  |  Kun Chen, MS; Liu Liu, MS; Runjie Shi, MD; Peihua Wang, MD; Dong Chen, MD; Hua Xiao, MD

Abstract

We conducted a retrospective study to evaluate the relationship between external auditory canal (EAC) anomaly, temporal bone abnormality, and hearing levels using objective scoring systems in Chinese patients with microtia. The study population consisted of 106 ears of 94...

Stapes-pyramidal fixation by a bony bar

April 30, 2017  |  N. Wendell Todd Jr., MD, MPH; Kai-Chieh Chan, MD

Glomus jugulare manifesting as angiogenesis of the external ear canal

March 24, 2017  |  Sei Y. Chung, BS; James K. Liu, MD, FACS; Richard Chan Woo Park, MD, FACS; Robert W. Jyung, MD

On otoscopic examination, one will usually see a red-blue vascular mass behind the tympanic membrane, often described as a “rising sun” emanating from the hypotympanum.

How successful is the fitting of digital hearing aids? Implications for the allocation of resources within national health systems

March 24, 2017  |  Petros V. Vlastarakos, MD, MSc, PhD; Alastair I. Cameron, BA (Hons), PGDip, MSc; Thomas P. Nikolopoulos, MD, DM, PhD

Abstract

We conducted a retrospective study to determine the success rate of initial fittings in digital hearing aid (DHA) users. We also addressed the implications of national health systems' continuing to provide access to these devices. We identified 1,597 consecutively presenting...

Analysis of caloric test responses in sudden hearing loss

February 20, 2017  |  Cheng-Ping Shih, MD; Yu-Ching Chou, PhD; Hsin-Chien Chen, MD, PhD; Jih-Chin Lee, MD; Yueng-Hsiang Chu, MD, PhD; Chih-Hung Wang, MD, PhD

Abstract

Sudden sensorineural hearing loss is characterized by a rapid-onset hearing loss that develops within 3 days. Vertigo may also be present. We conducted a retrospective study to investigate whether the severity of a loss of caloric function is associated with the initial hearing...

Evaluation of patient satisfaction with different hearing aids: A study of 107 patients

January 25, 2017  |  Seçkin Ulusoy, MD; Nuray Bayar Muluk, MD; Turhan San, MD; Cemal Cingi, MD

Abstract

We retrospectively investigated patient satisfaction with different types of hearing aids in 107 patients-60 males and 47 females, aged 8 to 84 years (mean: 53.8)-with unilateral or bilateral hearing loss, each of whom used two different hearing devices for at least 3 years per...

Mucous retention cyst of mastoid bone mimicking cholesteatoma

January 25, 2017  |  Nurdoğan Ata, MD; Suna Erkılıç, MD

Occlusion of mastoid cells and the aditus ad antrum caused by inflammatory diseases can result in poor ventilation and poor drainage of mastoid cells, which can in turn cause the formation of cysts.

Primary solitary intralabyrinthine schwannoma: A report of 7 cases and a review of the literature

December 7, 2016  |  Avi Shupak, MD; Yehuda Holdstein, MD; Margalit Kaminer, MSc; Itzhak Braverman, MD

Abstract

Intralabyrinthine schwannomas (ILSs) are uncommon benign tumors that originate in the Schwann cell sheath of the intralabyrinthine distal branches of the vestibulocochlear nerve. They have no initial involvement in the internal auditory canal, although that might develop later...

Stapes-pyramidal fixation by a bony bar

October 25, 2016  |  Kai-Chieh Chan, MD

Stapes fixation caused by an ossified stapedius tendon with normal mobility of the footplate, although rare, should be included in the differential diagnosis of conductive hearing loss with a normal tympanic membrane.

Sensorineural hearing loss after otitis media with effusion and subacute mastoiditis after viral infections of the upper respiratory tract: A comparative study of conservative and surgical treatment

September 19, 2016  |  Thomas Wilhelm, MD, PhD; Tim Stelzer, MD; Rudolf Hagen, MD, PhD

Abstract

Involvement of the middle ear after viral infections of the upper airways may lead to serous otitis media with effusion in the absence of bacterial infection. This can be accompanied by a concomitant shading of the mastoid air cells, which could manifest as a reduced opacity on...

Are routine preoperative CT scans necessary in adult cochlear implantation? Implications for the allocation of resources in cochlear implant programs

August 21, 2016  |  Bruno Kenway, MRCS, DO-HNS; Petros V. Vlastarakos, MD, MSc, PhD; Anand V. Kasbekar, MRCS, DO-HNS; Patrick R. Axon, MD, FRCS(ORL-HNS); Neil Donnelly, MSc, FRCS(ORL-HNS)

Abstract

Our aim was to critically assess the influence of preoperative computed tomography (CT) scans on implantation decisions for adult cochlear implant candidates. The working hypothesis was that these routine scans might not provide critical additional information in most adult...

Effects on auditory function of chronic exposure to electromagnetic fields from mobile phones

August 21, 2016  |  Sanjeev Bhagat, MS(ENT); Saurabh Varshney, MS(ENT); Sampan Singh Bist, MS(ENT); Deepak Goel, DM(Neurology); Sarita Mishra, MS(ENT); Vivek Kumar Jha, MSLAP

Abstract

The widespread use of mobile phones has given rise to apprehension regarding the possible hazardous health effects of high-frequency electromagnetic fields (EMFs) on auditory function. We conducted a study to investigate the effects of long-term (>4 yr) exposure to EMFs...
