Nevus is a benign melanocytic neoplasm and the most common type of skin tumor. It may occur anywhere on the skin, but it is rare in the external auditory canal (EAC). We present a case of melanocytic nevus in the EAC with keratin accumulation. In microscopic surgery, the mass was excised completely, and the wax and keratin material medial portion of the EAC behind the mass was removed. In this patient, a melanocytic nevus in the EAC caused symptoms of hearing loss and wax and keratin buildup. For melanocytic nevus in the EAC, excision and pathologic confirmation should be performed if there are symptoms or when malignant transformation is suspected.

Introduction: Epidermolysis bullosa (EB) is a spectrum of mechanobullous disorders characterized by blistering following minor trauma or traction to the skin. Hearing loss in this population is poorly described in the otolaryngology literature, and its treatment oftentimes results in external auditory canal skin irritation. Case Presentation: We present the case of a 26-year-old female with EB and mixed hearing loss unable to wear conventional hearing aids due to sequelae of the external auditory canals. An osseointegrated implant was used as other hearing aids were deemed to be too destructive of the external auditory canal skin. Management and Outcome: Our patient underwent placement of a right bone-anchored hearing aid with minimal disruption of the surrounding skin using a minimally invasive punch technique. Over 1 year of follow-up, her course was complicated by 1 simple cellulitic infection at the surgical site treated successfully with oral antibiotics. Discussion: The literature regarding the otolaryngologic manifestations of EB is sparse. The otologic sequelae are particularly overlooked in the workup and management. Based on the results of this case study, it appears that an osseointegrated implant can be safely utilized to treat significant mixed or conductive hearing loss in patients with EB.

Purpose: It was intended to measure the sound intensity of children's sound books and to compare them with the standards of Korea and the International Standards Organization (ISO).Methods: The loudness of 15 children’s sound books was measured at a distance of 25 cm (child’s arm length), and 2.5 cm length of external auditory canal. Measurements taken three times with each book were performed, and the overall sound intensity of the sound books and the sound intensity of each button were measured and compared.Results: Compared with the Korean standard, all the buttons of all books exceeded the standard for the sound volume of the children’s book measured at a distance of 2.5 cm. When comparing the maximum sound intensity measured at a distance of 25 cm with 85 LAmax, a total of 168 buttons of these, 25 (14.88%) were recorded as exceeding the maximum loudness. According to the standards of the ISO, all buttons in all books were below the standard 85 LAeq.Conclusion: Several children’s books are loud enough to cause noise-induced hearing loss, especially when they are placed close to the ear. Strict standards for sound children’s books are required, and it is important to put a warning on the cover of the book. It is expected that the sound intensity of the children’s sound book presented in this study can be referenced when referring to the loudness during hearing rehabilitation in children.

Otosurgery plays an important role in the rehabilitation of patients with hearing loss. Any operation can be accompanied by a long inflammatory process with excessive development of connective tissue, forming atresia or stenosis of the external auditory canal. Formed scars in the external auditory canal reduce the effectiveness of treatment and can lead to reoperation. In the treatment of scars, the use of injections of a suspension of prolonged steroids directly into the developing connective tissue is effective. We have developed a method of injecting drugs into the scar tissue of the bone section of the external auditory canal, which allows the use of such therapy in patients after otosurgery. 12 people were treated with the proposed technique. All patients had an inflammatory process in the external auditory canal with undesirable growth of connective tissue. Previous local therapy did not bring a satisfactory result. Patients received injections of a suspension of steroids into developing scar tissue. The treatment period was 1-8 weeks, for which 1 to 4 sessions of injections were performed. As a result of treatment according to the developed method, in all cases a cessation of the pathological inflammatory process was observed. Timely therapy made it possible to completely eliminate the excess granulation tissue (100%), to stop the growth of the scar, or even to cause a significant decrease (33%). The developed method allows to use of a small dose of a substance (0,1–0,5 ml) for injection to achieve the desired therapeutic effect.

Three patients with extensive keratosis obturans were treated during a 12-month period. One presented with an idiopathic sensorineural hearing loss and was found to have keratosis obturans in the contralateral, asymptomatic ear. The disease process had resulted in a horizontal semicircular canal fistula in what was now, effectively, the only hearing ear. The second patient had an extensive dehiscence of the tegmen tympani. The third presented with a facial palsy. An automastoidectomy cavity was present, with circumferential skeletonization of the descending facial nerve over a length of 1.5 cm and dehiscence of the temporomandibular joint and jugular bulb. All three patients were successfully treated by surgical formalization of their automastoidectomy cavities. They appeared to represent cases of keratosis obturans rather than external auditory canal cholesteatoma, on the basis of previously published reports.These complications and patterns of bone erosion have not previously been described in keratosis obturans. The third patient is believed to have the most extensive case of keratosis obturans yet described.

An acoustic neurinoma involving the internal auditory canal, the vestibule, the cochlea, the middle ear, and extending into the cerebellopontine angle and the external auditory canal, is described in a 56-year-old woman. An initial episode of vertigo was followed by a 27-year history of progressive unilateral hearing loss leading to complete deafness and areflexia with central compensation. The tumor was removed by a two-step surgical procedure, and the histologic features were those of a schwannoma.
