Analysis of Risk Factors for Myringosclerosis Formation after Ventilation Tube Insertion

Background@#This study examined possible risk factors for myringosclerosis formation after ventilation tube insertion (VTI). @*Methods@#A retrospective study was performed in a single tertiary referral center. A total of 582 patients who underwent VTI were enrolled in this study. Patients were divided into two groups based on the presence or absence of myringosclerosis: MS+ and MS−. Characteristics of patients were collected through medical chart review; these included age, gender, nature and duration of effusion, type of ventilation tube (VT), duration and frequency of VTI, incidence of post-VTI infection, incidence of intraoperative bleeding, and presence of postoperative perforation. Incidences of risk factors for myringosclerosis and the severity of myringosclerosis in association with possible risk factors were analyzed. @*Results@#Myringosclerosis developed in 168 of 582 patients (28.9%) after VTI. Patients in the MS+ group had an older mean age than those in the MS− group. The rates of myringosclerosis were higher in patients with older age, serous otitis media, type 2 VT, post-VTI perforation, and frequent VTI. However, there were no differences in occurrence of myringosclerosis based on gender, duration of effusion, duration of VT placement, incidence of post-VTI infection, or incidence of intraoperative bleeding. The severity of myringosclerosis was associated with the duration of effusion and frequency of VTI. @*Conclusion@#Older age, serous effusion, type 2 VT, presence of post-VTI perforation, and frequent VTI may be risk factors for myringosclerosis after VTI; the severity of myringosclerosis may vary based on the duration of effusion and frequency of VTI.

A Case of Langerhans Cell Sarcoma Presenting as Submandibular Gland Mass / 대한이비인후과학회지

Langerhans cell sarcoma is a rare, proliferative tumor of Langerhans cells, which shows cytologic characteristics and clinical features of malignant tumor. Langerhans cell sarcoma primarily occurs in lymph nodes, skin, lung, liver, and spleen. However, very few cases have been reported in the head and neck region. Because of its rarity, an optimal treatment approach is unknown; however, Langerhans cell sarcoma grows aggressively and shows a poor prognosis, such that a more aggressive and multi-modality treatment approach is necessary. Here, we report the case of a 36-year-old male with Langerhans cell sarcoma, who presented with a mass in the submandibular gland area and was treated with wide excision and postoperative radiotherapy.

Clinical Characteristics of Temporal Bone Metastases

OBJECTIVES: The purposes of this study were to evaluate the clinical characteristics of temporal bone metastasis (TBM) and to determine whether the characteristics differed according to primary malignancy. METHODS: We retrospectively analyzed data on 20 patients diagnosed with TBM between January 2000 and January 2017. Demographics, the period from diagnosis of primary malignancy to TBM diagnosis, the period from TBM diagnosis to death, the type and staging of primary malignancy, otologic manifestations, and TBM sites were assessed. After the primary malignancies were divided into solid cancers and hematologic malignancies, each parameter was compared between the two groups. RESULTS: The most common primary malignancy with TBM was lung cancer (45%). The most common otologic symptoms and signs were facial palsy (30.5%) and hearing loss (30.5%). The temporal squama (23%) and the facial nerve (20%) were the most commonly involved. Most TBMs occurred late in the disease process after the primary malignancy first metastasized to other organs. Hematologic malignancies metastasized significantly more frequently to the external auditory canal and the middle ear/mastoid compared to solid cancers (P=0.001 and P=0.004, respectively). CONCLUSION: If otologic manifestations such as facial palsy and hearing loss are presented in patients at advanced stages of malignancy, TBM of primary malignancy should be suspected. In addition, hematologic malignancies tend to metastasize to the external auditory canal and the middle ear cleft more commonly than solid cancers do.

A Case of Retropharyngeal Huge Lipoma Causing Dysphagia / 대한이비인후과학회지

Lipomas of the retropharyngeal space are rare, and they do not cause symptoms until they reach a large size. Although retropharyngeal lipoma is an uncommon entity, several reports have appeared about it in the literature, where the treatment has routinely been surgical excision. We present a case of huge lipoma of the retropharyngeal space. It extended from the oropharynx to the inferior portion of thyroid gland, causing symptoms of globus and dysphagia in a 74-year-old male. The patient had multiple medical problems and had been on anticoagulants, so we approached the mass via transcervical incision. After a complete surgical resection, all the symptoms of the patient improved. A large retropharyngeal lipoma could also be differentially diagnosed as a laryngopharyngeal mass presenting symptoms of globus and dysphagia.
