Paranasal sinus mucoceles are benign non-neoplastic condition characterized by cystic expansion. They are classified into primary and secondary mucoceles by known causes. Most mucoceles are located in the frontal and anterior ethmoid sinuses and they involve the frontoethmoial region, expanding to the region of the orbit, leading to the ocular symptoms. The primary maxillary sinus mucoceles are not common, whereas secondary ones such as postoperative maxillary sinus mucoceles (POMMs) developing after Caldwell-Luc operation are pretty common. POMMs have often multiple septated mucoceles. However, most of the primary maxillary sinus mucoceles are an expansile and cystic mass of maxillary sinus with medial bulging. We present a case of primary septated mucocele in the maxillary sinus of a 36-year-old male who underwent revision surgery. Korean J Otorhinolaryngol-Head Neck Surg 2016;59(12):865-8
비강내 악성종물로 오인된 부비동의 Immunoglobulin G4 연관 경화성 질환 1예

Immunoglobulin G4 (IgG4)-related sclerosing disease (RSD) is a chronic inflammatory disorder characterized by elevated serum IgG4 levels as well as an abundant infiltration of IgG4-positive plasmacytes. Involvement of the paranasal sinus is very rare, so it is difficult to make an accurate diagnosis. Hence, various differential diagnoses, which typically include elevated serum IgG4 levels and the infiltration of IgG4-postive cells into tissues, need to be excluded, especially for malignant diseases and mimicking disorders. Systemic corticosteroids are generally effective at inducing IgG4-RSD remission. Recently, a 43-yearold woman presented with a mass originating from the ethmoid sinus, suggesting malignancy. The patient underwent biopsy of the lesion. The pathologic specimen revealed the magnitude of IgG4-positive plasma cell infiltration, which was consistent with IgG4-RSD. In addition, serum IgG4 levels were markedly increased. After glucocorticoid treatment, the serum IgG4 levels decreased and the symptoms improved. We present a rare case of IgG4-RSD with isolated involvement of the paranasal sinuses.

Otalgia consists of primary otalgia associated with disorders of the ear itself and referred otalgia due to disorders of organs that share the same innervation with the ear. Disorders of the oral cavity and laryngopharynx served by the glossopharyngeal and vagus nerves are common causes of referred otalgia. Chest pain from myocardial infarction spreads through the afferent pain pathway, especially through the sympathetic nerves in the cardiac plexus and the phrenic nerve, resulting in a typical chest pain or referred pain in the left upper extremity. However, pain spreading through the vagus nerve can theoretically cause referred otalgia. This association between the heart and ear has not been widely acknowledged, even though a referred otalgia can occasionally be the only symptom of the tragic disease, myocardial infarction, and should be taken seriously. We report a patient who complained of left otalgia as the only symptom of myocardial infarction. Korean J Otorhinolaryngol-Head Neck Surg 2017;60(6):322-5

Dehiscence of the bone overlying the semicircular canals has been shown to have effects on vestibular and auditory function. This case report presents a 48-year-old man presenting atypical vestibular manifestations and bilateral hearing loss. His temporal bone CT scans demonstrated bony dehiscence of posterior semicircular canal and vestibule in the right, superior and posterior semicircular canals in the left.

A number of studies have demonstrated a significant association between age-related hearingloss (ARHL) and cognitive decline. However their relationship is not clear. In this review, wefocused on the etiological mechanisms between ARHL and cognitive decline to explain thenature of this relationship: 1) causal mechanisms (e.g., cognitive load hypothesis, cascade hypothesis);2) common cause mechanisms (e.g., microvascular disease); 3) overdiagnosis or harbingerhypothesis. We conclude that no single mechanism is sufficient and hearing and cognitionrelated to each other in several different ways. In addition, we reviewed the effectivenessof hearing intervention (e.g., hearing aids and cochlear implants) on cognition function, andthe role of hearing aid use and cochlear implant depends on the relevant mechanism.

This paper investigates whether a secondary teacher trainee improved pair/group work management skills in a short-term teacher training program focusing on the development of TEE-related skills. One female teacher trainee, students, and a teacher trainer participated in the study. The participant’s teaching performance, conference on her teaching performance, lesson plans, and the teacher trainer’s feedback on the teaching performances were collected. The data on teaching performance and conferencing were transcribed and analyzed in terms of a moving-in phase, a monitoring phase, and a moving-out phase. The participant showed improvement in changing seating arrangement, selecting students in modeling, increasing various kinds of comprehension check up questions, changing her voice during monitoring, and drawing students’ attention and signaling a new phase of lesson to the students in a moving-out of the activity. This study suggests how to improve management skills in pair/group work in TEE classes.
