![]() It is approximately 3 cm long and is lined by skin containing hair follicles (tragi), sebaceous glands, and ceruminous glands (which produce cerumen ). Dermatitis of the Ear Canal (Chronic Otitis Externa) - Etiology, pathophysiology, symptoms, signs, diagnosis & prognosis from the Merck Manuals - Medical. ![]() It can also serve as a clinical textbook for those involved in the surgical and audiological treatment of the microtia/atresia of the EAC within a clinical setting. The external auditory meatus is a short S-shaped canal within the tympanic temporal bone leading from the external acoustic pore of the auricle to the tympanic membrane. This publication is a valuable reference not only for plastic surgery and otolaryngology departments, but also for speech therapists, school teachers and patients’ families. The walls of the external 1/3 are formed by cartilage, whereas the inner 2/3 are formed by the temporal bone. Collaborative surgery offers advantages not only in terms of a better reconstruction of morphology and function, but also in terms of the lower number of surgical procedures required which reduces the psychological pressure and economic burden on patients. The external acoustic meatus is a sigmoid shaped tube that extends from the deep part of the concha to the tympanic membrane. Based on this concept, information on diagnosis, surgical procedures, outcomes, long-term results and psychology is discussed. Abbreviations External auditory canal (EAC) Synonyms Surfer's ear Cold water ear Definitions Benign hyperostotic outgrowths of bony EAC. This book presents the latest findings on reconstructive surgery performed jointly by plastic surgeons and otologists. Teaching point: Always ask a patient to open and close their mouth when you see a mass protruding into the external auditory canal, as to not miss this rare. The External Acoustic Meatus (meatus acusticus externus external auditory canal or meatus) extends from the bottom of the concha to the tympanic membrane. The mandibular condyle sits anterior to the bony portion of the external acoustic meatus (external auditory canal). The canal measures about 4 cm in length (from the tragus) to the tympanic membrane and is curved in an S shape. ![]() Helical computed tomography has made a three-dimensional reconstruction of the soft tissue of the temporal bone surface and the cranium possible, and has laid the groundwork for a collaboration between plastic surgeons and otologists. The external acoustic meatus (external auditory canal) is formed by cartilage and bone (temporal). ![]() Remarkable progress in the development of new concepts and techniques used in reconstructive surgery of microtia/atresia of the external auditory canal (EAC) has been made since the beginning of the 21st century. ![]()
