White-Eyed Orbital Blowout Fracture: A Retrospective Study of 22 Patients / 대한이비인후과학회지

Background and Objectives@#The study reports on the clinical experience of repairing white-eyed orbital blow out fracture through a retrospective study of various incidences of white-eyed orbital blow out fracture that resulted in different treatment methods and outcomes.Subjects and Method A retrospective study was performed on 22 patients with white-eyed blowout fracture who underwent operation between March 2009 and June 2019 at our clinic. Patients were divided into 2 groups by age: 6 to 12 and 13 to 18. A review of medical records included demographic data, cause of injury, preoperative symptoms, trauma to operation time and surgical outcomes including improvement of postoperative ocular symptoms and complications. @*Results@#The study population included 20 males and 2 female patients ranging from 6 to 18 years (mean, 14.2 years) of age. Fifteen of 21 patients with diplopia or limitation of eyeball movement showed a complete improvement of symptoms after surgery and 6 (28.5%) had remaining symptoms. One patient had no ocular symptom, but had oculocardiac reflex including nausea and vomiting. Two cases were re-operated due to adhesion of graft material. There was one sinus infection related to the implant. @*Conclusion@#This study shows that early reconstruction and release of incarcerated muscle within 5 days after trauma for white-eyed blowout fracture gives successful result that does not accompany major complications. All of the 22 patients who were operated for white-eyed blowout fractures had successful results.

A Case of Parotid Tuberculosis Mimicking Benign Tumor of Parotid Gland / 대한두경부종양학회지

Tuberculosis of parotid gland is extremely rare, even in countries where tuberculosis is endemic. It can occur by systemic dissemination from a distant focus or as primary involvement. Because of the clinical and radiological similarity, parotid tumor and parotid inflammatory disease take priority over the tuberculosis of parotid when it comes to differential diagnosis. As a result, clinicians often fail to make a timely diagnosis of tuberculosis of parotid gland in patient with a slowly growing parotid mass. However, its treatment is primarily medical if the positive diagnosis is well established. We have recently experienced a case of tuberculosis of parotid gland that was considered as the benign tumor preoperatively, but which was confirmed as tuberculosis of parotid gland after extracapsular dissection. We report it with a review of literature.

A Case of Cervical Retrotracheal Metastatic Papillary Thyroid Carcinoma Diagnosed by Endobronchial Ultrasonography with Transbronchial Needle Aspiration

A 61-year-old woman who underwent total thyroidectomy for papillary thyroid carcinoma (PTC) five years previously referred for a cervical retrotracheal mass. The mass had intense fluorodeoxyglucose (FDG) uptake on positron emission tomography-computed tomography (PET-CT), and was thus thought to be malignant. Transcutaneous ultrasonography with fine needle aspiration (FNA) was not feasible, so we tried endobronchial ultrasonography (EBUS) with transbronchial needle aspiration (TBNA) to obtain a cytology specimen. After surgery, the mass was confirmed to be a metastatic lymph node from the previous PTC, confirming the TBNA results. Although the utility of EBUS-TBNA for evaluating mediastinal metastasis has been reported in a number of studies, few reports have addressed its utility in the cervical region. Here we report this unusual case of metastatic lymph node of PTC that recurred in the cervical retrotracheal area. It was found to exhibit esophageal muscular invasion, and was accurately diagnosed on EBUS-TBNA.

A Case of Vogt-Koyanagi-Harada Syndrome with Vertigo and Hearing Loss / 대한이비인후과학회지

Vogt-Koyanagi-Harada (VKH) syndrome is an uncommon multisystem autoimmune disease affecting the melanocytes located in the uvea, inner ear, skin, hair, and meninges. The syndrome is frequently reported by ophthalmologists since the most consistent finding is uveitis. Hearing loss, tinnitus and vertigo are the symptoms of VKH syndrome. The authors report one case of VKH syndrome with hearing loss and vertigo with related literature.

Relationship between Degree of Enophthalmos and Orbital Volume Measured with Computed Tomography in Isolated Blowout Fractures of the Orbit / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: We investigated the relationship between the degree of enophthalmos and the volume of herniated orbital tissue measured from computed tomography scan in the isolated blowout fractures of orbital wall. SUBJECTS AND METHOD: In this retrospective study, 100 patients with isolated blowout fractures were evaluated. We classified them into 4 groups according to the site of fracture (medial and inferior) and the presence of symptoms like diplopia and limitation of ocular motility, which needs an operation. The volume of orbit and herniated orbital tissue has been measured by computed tomography scans using three-dimensional reconstruction technique, and the degree of enophthalmos was evaluated with Hertel's ophthalmometer. We compared the volume from which we got from the computed tomography scan, the degree of enophthalmos and the presence of symptoms to figure out the mutual relation between the groups. RESULTS: In the case of medial blowout fracture group, the volume of herniated orbital tissues increased significantly with the presence of symptoms and was in proportion to the extent of enophthalmos (p<0.05). The volume expansion of orbit associated with 2 mm of enophthalmos as calculated by the regression curve was 3.1 ml or 12.8 % in the no-symptoms groups. Finally, in the case of inferior blowout fracture group, there was no evidence of mutual relation. CONCLUSION: These results suggest that surgical intervention is required even though there isn't any symptom for medial blowout fractures, especially when the orbit volume is more than 12.8%. In cases of inferior blowout fractures, a close follow-up is needed even though the extent of fracture is small.
