Exostosis in external auditory canal is common among surfers. Common symptoms are decreased hearing or loss of hearing, ear infection, and/or plugging sensation. Repeated exposure to cold water is a key clinical history to suspect this condition. Based on symptoms and existence of infection, surgical removal of the exostosis is recommended.

The 2017 fourth edition of the World Health Organization Classification of Tumours, specifically as it relates to the ear (Chap. 9), has several changes. Importantly, the number of entities has been significantly reduced by omitting tumors or lesions if they do not occur exclusively or predominantly at this site or if they are discussed in detail elsewhere in the book. These entities include: embryonal rhabdomyosarcoma, osteoma, exostosis, angiolymphoid hyperplasia with eosinophilia, Schneiderian papilloma, inverted papilloma, lipoma of the internal auditory canal, hemangioma, hematolymphoid tumors, and secondary tumors...

CONCLUSIONS: External ear canal exostosis is more prevalent in northern coastal groups than in the highlands, suggesting that ocean activities facilitate the appearance of exostosis. However, southern coastal groups exposed to colder ocean water have a lesser incidence of exostosis, possibly due to less duration of exposure. There was a high incidence of otitis media in all groups of native population in Chile. One coastal group had a higher incidence, presumably due to racial factors...

INTRODUCTION: Optic nerve compression is an uncommon disorder leading to deterioration or complete loss of vision. CASE PRESENTATION: We describe the case of a 14-year-old Caucasian girl with a gradual deterioration of vision in her right eye. Using modern imaging techniques and endonasal endoscopic surgery, we identified the cause and removed the pathology. CONCLUSIONS: The cause of optic nerve compression was a rare exostosis in the optic canal...

Exostoses are bony outgrowths of the external auditory canal (EAC) that can lead to cerumen entrapment, recurrent infections, and conductive hearing loss. When surgical removal is indicated, a drill or osteotome may be used via a post-auricular, endaural, or transcanal approach. Studies suggest that exostoses removed by transcanal osteotome result in decreased morbidity when compared to open, drilled approaches; however, inadvertent injury to the facial nerve or inner ear is a theoretical concern given the restrictive geometry of the EAC and challenges of visualizing the tip of the chisel through the microscope...

To examine how individual surfing behaviour affects the development of external auditory canal exostosis and to produce a model to predict exostosis severity. A standardised questionnaire was completed and each participant underwent an otoscopic examination. Surfers were recruited from August to October 2011 from surfing competitions and from colleges in the South West of England. 207 surfers were included, 53 % had evidence of external auditory canal; exostosis: grade 1, 23%; grade 2, 16%, grade 3, 16%. This risk of exostosis significantly increased with (1) surfing for 6 or more years, (2) surfing in the winter months, (3) surfing five or more times per month in the winter and (4) reported ear symptoms...

Exostoses are benign bony excrescences of the external auditory canal, commonly encountered in people who avidly engage in aquatic activities, hence the name "surfer's ear". Exostoses are more prevalent in cold water surfers, and additional years of surfing increase one's risk not only for developing an exostosis but also for developing more severe lesions. Exostoses remain clinically silent until they become large enough to impair the egress of epithelial debris and water from the canal, in which case there may be an associated external otitis and fluctuating hearing loss...

There is a great deal of literature regarding the tori of the mouth and ear. However, there is controversy regarding the etiology and prevalence of each. The torus palatinus is generally agreed to be the most common oral exostosis and is more frequently found in females. The torus mandibularis is also quite common, is more prevalent in males, and occurs bilaterally in 80% of cases. Far less data have been presented regarding the torus maxillaries primarily due to the lack of consensus regarding its nomenclature and classification...

History of underwater diving dates back to antiquity. Breath-hold technique in diving was known to the ancient nations. However, deep diving progressed only in the early decades of the 19th century as the result of advancements in efficient underwater technologies which subsequently led to invention of sophisticated sets of scuba diving in the 20th century. Currently, diving is performed for various purposes including commercial, recreational, military, underwater construction, oil industry, underwater archeology and scientific assessment of marine life...

INTRODUCTION AND OBJECTIVES: Benign lesions of the external auditory canal (EAC) are an infrequent cause of temporal bone CT scan requests. We are not usually well versed in the different pathologies located in the EAC, perhaps because it is "only" a conduit and the relevant anatomical structures are located in the middle and inner ear. Our objective was to improve knowledge of this structure by reviewing the different benign conditions found in this location. METHODS: We reviewed the CT studies from 2 years (January 2010 through January 2012), selecting those containing lesions in the EAC...

Diseases of the external ear canal are a frequent reason for consulting the otolaryngologist. Conservative treatment is sufficient in most cases. Chronic problems of the external ear canal, however, sometimes require surgical treatment. Enlargement of the external ear canal as well as the entrance of the external ear canal are often simultaneously performed together with tympanoplasties, in order to obtain good access to the middle ear and to facilitate postoperative care. In this review, we focus on surgical techniques for different pathologies such as exostosis, stenosis, fibrosis, and tumors of the external ear canal...

OBJECTIVE: The objective of this study was to demonstrate the prevalence and severity of external auditory canal exostoses in a population of competitive surfers in Japan. The authors used a “surfing index,” the product of the period (years) as an active surfer and the frequency (number of surfing days per week), to predict external auditory exostoses formation. STUDY DESIGN: Cross-sectional study. SETTING: A total of 5 surfing competitions that were held in Miyazaki, Japan...
