#1
P H Rhys Evans, M Cameron
For over a century, otolaryngologists have recognised the condition of aural exostoses, but their significance and aetiology remains obscure, although they tend to be associated with frequent swimming and cold water immersion of the auditory canal. The fact that this condition is usually bilateral is predictable since both ears are immersed in water. However, why do exostoses only grow in swimmers and why do they grow in the deep bony meatus at two or three constant sites? Furthermore, from an evolutionary point of view, what is or was the purpose and function of these rather incongruous protrusions? In recent decades, paleoanthropological evidence has challenged ideas about early hominid evolution...

Introduction  Acquired atresia of the external auditory canal is characterized by the formation of fibrous tissue in the medial part. The causes include chronic otitis externa, perforated chronic otitis media, postoperative or idiopathic healing problems. Acquired atresia presents with hearing loss and can be associated with otorrhea. Objective  We analyzed the results of surgery after six months and two years by checking (1) pre- and postoperative hearing thresholds; (2) presence of otorrhea; and (3) whether a dry and patent ear canal is achieved...

OBJECTIVES: Several cytokines and innate immune-associated molecules are present in middle ear effusions, but damage-associated molecular patterns (DAMPs) in middle ear effusion have not been studied. Therefore, we evaluated the role of heat shock proteins (Hsps) in the development of otitis media with effusion (OME). METHODS: Serous middle ear effusions from 22 pediatric patients who were diagnosed with OME and underwent ventilation tube insertion from June 2015 to March 2017 were evaluated in our study...

The authors tested the hypothesis that there is a correlation between hemispheric cognitive style and ear temperature. A sample of 100 participants completed a measure of hemispheric cognitive style, the Hemispheric Consensus Prediction Profile. Ear temperatures were taken in 2 sessions, 2 times for each ear at each session. Average left ear temperature was subtracted from average right ear temperature as an index of dominant temperature. Only 56 of the participants showed a stable dominant ear temperature...

The purposes of this study were to determine if use of a powered drill or trainee involvement during tympanoplasty is associated with a decline in sensorineural hearing, as well as to examine whether trainee involvement affected tympanic membrane (TM) closure rates. This study was a chart review (February 2006 to October 2011) of 172 pediatric otolaryngology patients undergoing type I tympanoplasty for TM perforation of any etiology at a tertiary-care pediatric otolaryngology practice. Data collected included air conduction (AC) at 250 to 8,000 Hz, speech reception thresholds, bone conduction (BC) at 500 to 4,000 Hz, and air-bone gap (ABG) at 500 to 4,000 Hz...

Baris B Koc, Martijn G M Schotanus, Jean-Paul A P A C Kollenburg, Maurice J A Janssen, Fabian Tijssen, Edwin J P Jansen
BACKGROUND: Hypothermia is an important complication in joint arthroplasty. Commonly, forced air warming (FAW) devices are used intraoperatively to maintain body temperature in patients undergoing surgery. However, it is believed that these convective warming systems could increase the risk of deep surgical site infections due to disruption of unidirectional downward laminar airflow. Conductive warming devices have no noticeable effect on ventilation airflow. Nevertheless, the effectiveness of the self-warming (SW) blanket, a novel conductive warming device, on postoperative hypothermia in elective joint arthroplasty is unknown...

Though granular myringitis (GM) is not a very rare disease it does not have any classification. Its exact etiology is not known. The granulations on tympanic membrane also occur in association with other lesions of external auditory canal (EAC) and middle ear. The aims of this study were to know the etiological factors of GM and classify the disease according to its etiological factors and associated disorders of EAC and middle ear. Data were retrieved from the search of four electronic databases: PubMed, EMBASE, Cochrane Library, and Google scholar...

Keratosis obturans appears to be an obscure and relatively uncommon entity, even in literature search of journals and reference texts, so much so that there is not even any prevalence or incidence statistics available. However, the condition did not appear to be as uncommon based on our clinical observations. We have managed to obtain 64 patients representing 67 ears with keratosis obturans in our study period of about 18 months with a pattern of occurrence during this period. Humid weather seemed to play a role in the frequency of its appearance during certain period in our observation...
