    <p> In recent years, the number of patients with allergic rhinitis (AR), including Japanese cedar pollinosis (JCP), has increased. Dr. Baba conducted epidemiological surveys in 1998 and 2008 to investigate the prevalence of AR in Japan, using questionnaires for otolaryngologists and their families. We carried out same questionnaire survey to investigate the changes in the prevalence of JCP, perennial allergic rhinitis (PAR), and pollinosis other than JCP in 2019. The results of our survey revealed a prevalence of AR of 49.2%, and a prevalence of JCP of 38.8%. These rates represented marked increases over the previously recorded results. Furthermore, a marked increase in incidence of JCP was observed in the younger age groups.</p>

    <p>Tracheoesophageal shunt utterance using a voice prosthesis as a substitute voice after laryngectomy is an excellent method and is widely used. However, in addition to temporary removal due to complications, the use of voice prostheses is occasionally discontinued for various reasons that lead to their permanent removal. We evaluated the voice acquisition rate, complications, and outcomes of 23 patients who underwent voice reconstruction using a voice prosthesis after total laryngectomy in our department from January 2007 to December 2018. The voice acquisition rate was 87%. Seven complications occurred in six cases, the most common of which was granulation, followed by leakage and infection in one case each, although all were eventually rescued. However, there were five cases where permanent voice prosthesis removal was necessary for reasons other than complications. Three of these patients had good voice acquisition but were unable to use the voice prosthesis due to the effects of other diseases. In the other two cases, a voice could not be obtained, and the patients expressed their desire to have the prosthesis removed. In the future, aging of voice prosthesis users and long-term use are expected, which will make it necessary not only to accurately determine the adaptation in consideration of the patient's intention, activity and living environment but also to consider how to proceed when voice prosthesis use becomes difficult due to other diseases.</p>

  • Diagnosis of hearing impairment in 48 children who were cleared at the newborn hearing screening

    <p> Seventeen years have passed since newborn hearing screening was first started in Akita prefecture, and the examination rate has exceeded 94% since 2012. While building a screening system, we firmly believe that collaboration to sustain the interest of related organizations in hearing impairment even beyond referrals from newborn hearing screening is necessary. In this study, we report diagnosing hearing impairment in some children who could not be identified by newborn hearing screening due to uncommon hearing types. This report is to emphasize that there are children with late-onset or progressive hearing impairment, and that it is therefore necessary to continue to strengthen cooperation with related organizations even after beyond referrals from newborn hearing screening. In this study, we confirmed that there are cases with incomplete diagnostic imaging, that cases with a genetic diagnosis may increase in the future, and that the number of confirmed cytomegalovirus infection follow-up cases is increasing. I conclude that there is a need to clarify the cause of delayed or progressive hearing loss in the future.</p>

  • SURGERY FOR FACIAL NERVE SCHWANOMA

    <p> Since the management of facial nerve schwannoma (FNS) is extremely rare intratemporal FNS has the potential to be misdiagnosed as Bell's palsy or intraparotid FNS might be often misdiagnosed as pleomorphic adenoma or another parotid tumor which might lead to a delay in diagnosis. In this manuscript, we have reviewed the literature regarding the management of IFNS and reported the authors' experiences in the treatment of IFNS. In patients with FNS, female sex and involvement of the labyrinthine/geniculate and tympanic segments of the facial nerve predict a higher probability of facial paresis or spasm. When isolated to the posterior fossa or parotid gland, establishing a preoperative diagnosis of FNS is challenging. The correct diagnosis for extratemporal FNS depends mainly on intraoperative observation of the gross relation between the tumor and the FN or excision frozen biopsy examination. Treatment should be tailored according to tumor location and size, existing facial nerve function, patient priorities, and age. The integrity of the FN should be preserved for patients with IFNS using tripping method whenever possible. In cases where the facial nerve has been interrupted during surgery, the cable nerve interpositioning technique is a convenient and well-accepted procedure for immediate restitution of the nerve. In order to obtain a better facial outcome, facial nerve is reconstructed also along with facial-hypoglossal nerve anastomosis at the same time. The physical rehabilitation is very important to decrease facial contracture and synkinesis.</p>

  • Thirteen cases of bear-inflicted injuries

    The number of patients attacked by bears has been rising recently because the opportunity to encounter wild bears has increased. Since injury by a bear attack mostly occurs in the head and neck region and can be fatal, adequate and immediate treatment is required.<br>We report 13 cases of injury inflicted by bears treated in our department and discuss the issues that are important in the treatment of these injuries. All 13 patients thought to have been attacked by black bears (<i>Ursus thibetanus japonicus</i>) suffered from facial contusions. Ten cases had facial bone fractures and four cases went blind in one eye. After the head and neck region, the arms had many injuries and three cases suffered bone fractures in their limbs and the trunk. Three patients developed hemorrhagic shock, however, there were no deaths. Four cases needed local flap reconstruction or skin grafting for defects of facial soft tissue.<br>It is important to know the features of injuries and to consult a specialist based on the sites and severity of the injuries for the treatment of bear-inflicted injuries.
