2.Septoplasty; Current Concept and Technique.
Journal of Rhinology 2008;15(1):13-29
Septoplasty is one of the most commonly performed operations in Otolaryngology. It is often considered an easy operation. Yet it is still accompanied by a relatively high rate of failure and complications. It is definitely not an operation in which one surgical technique can suffice for all circumstances. Rather it requires a variety of techniques in accordance to the various septal pathologies in order to achieve a favorable outcome. This study provides a comprehensive review of septoplasty including current concepts, historical background, classification, updated surgical techniques, and management of complications. In particular, the surgical techniques that ensure a successful correction and minimal complications are highlighted.

3.Contemporary Methods of Upper Airway Evaluation in Obstructive Sleep Apnea Patients.
Korean Journal of Otolaryngology - Head and Neck Surgery 2013;56(1):7-13
Obstructive sleep apnea is a manifestation of upper airway instability leading to upper airway collapse during sleep. Current diagnostic testing with polysomnography provides information regarding the number of apneas and hypopneas but does not provide any information regarding the level of pharyngeal narrowing or collapse. The identification of the site of obstruction is essential in choosing the appropriate treatment, especially when surgical intervention is considered. In this review we present contemporary methods for localizing obstructive sites with emphasis on two promising airway evaluation modalities. Sleep videofluoroscopy and sleep en-doscopy. Further understanding of the obstructive events occurring during sleep with precise evaluation of the sites of obstruction will eventually guide tailored surgical treatment with improved surgical outcomes.

4.Management of Skull Base Osteoradionecrosis
Korean Journal of Otolaryngology - Head and Neck Surgery 2020;63(2):51-58
Osteoradionecrosis of the skull base (SB-ORN) is a serious potentially lethal complication after radiotherapy in the head and neck region and is therefore considered one of the most challenging clinical entities among skull base lesions. Management options includes nasal irrigation, medications such as systemic antibiotics and anti-inflammatory drugs, hyperbaric oxygen therapy, and surgical debridement. Despite these efforts treatment outcomes are associated with a poor prognosis. Recent studies have shown an increased disease control rate with a more aggressive surgical approach including sequestrectomy. One of the main factors associated with poor prognosis is involvement of the internal carotid artery near the skull base. Spontaneous carotid rupture is frequently associated with death and/or severe morbidity and also poses risk of profuse bleeding during surgery. In this article we will deliver a comprehensive review of SB-ORN, including pathophysiology, clinical features, and an update in treatment strategy.

Palisaded neutrophilic and granulomatous dermatitis (PNGD) is an uncommon skin eruption and characterized histopathologically by the presence of granulomatous inflammation with or without leukocytoclastic vasculitis. PNGD is known to be associated with various immune-mediated connective tissue diseases such as rheumatoid arthritis and lupus erythematosus. However, to our knowledge, a case of PNGD in a patient with Behçet’s disease is extremely rare and only one case has been reported in foreign literature to date. Herein, we report an unusual case of a 60-year-old female with Behçet’s disease who presented multiple erythematous to flesh-colored papules on the extremities, buttocks, and ear lobes and was diagnosed with PNGD. After the treatment of systemic corticosteroids, colchicine and azathioprine, the skin lesions and oral ulcers improved. The patient is under observation without recurrence of skin lesions for 6 months.
6.Management of Nasal Valve Dysfunction
Clinical and Experimental Otorhinolaryngology 2024;17(3):189-197
Nasal valve dysfunction can substantially impact nasal airflow and overall quality of life. This review provides a comprehensive examination of nasal valve dysfunction, including its mechanisms, classification, and surgical management. The nasal valves include internal and external valves, each of which plays a crucial role in regulating nasal airflow. Subclassification of the external nasal valve into alar and rim valves helps specify the site of obstruction when present and informs the choice of surgical intervention. Dynamic nasal valve obstruction, often characterized by inspiratory collapse of the nasal valve, must be distinguished from static obstruction, which refers to nasal valve stenosis. Accurate identification of the location and mechanism of nasal valve dysfunction is essential for effective management. Various surgical procedures target specific components of the nasal valve and can produce favorable functional outcomes. The selection of surgical procedures, whether individually or in combination, should be tailored to the characteristics of nasal valve dysfunction and the external nasal characteristics of the patient. Strict adherence to proper surgical techniques is imperative for achieving optimal treatment outcomes.

Shunt malfunctions that require surgical intervention during pregnancy and the postpartum period are rare. Furthermore, no study has reported on an acute shunt malfunction immediately after cesarean section. Here, we describe the case of a 32-yr-old woman who became drowsy 12 hr after cesarean section delivery of her second child. She had a ventriculoperitoneal shunt placed to treat hydrocephalus associated with meningitis at 26 yr of age. Marked ventriculomegaly was seen on brain computed tomography and her consciousness recovered temporarily after aspirating cerebrospinal fluid from the flushing device. At surgery, the distal catheter tip was plugged by a blood clot. We believe that the blood spilled over during the cesarean section. The clogged catheter end was simply cut off and the remaining catheter was repositioned in the peritoneal cavity. Her consciousness recovered fully.

OBJECTIVES: Currently established first line therapy of acute (presumed bacterial) rhinosinusitis (ARS) consists of 10 to 14 days of oral amoxicillin or cephalosporins. This study compared the clinical efficacy and tolerance of cefcapene pivoxil (CP) and amoxicillin-clavulanate (AMC) in patients with ARS. METHODS: A randomized, open labeled, double-blinded trial of ARS patients over 15 years of age was performed. Patients diagnosed with ARS received paranasal sinus X-rays and nasal endoscopies and 2 weeks of either CP (150 mg, 3 times/ day) or AMC (625 mg, amoxicillin 500 mg, 3 times/day). All patients revisited the clinic on days 7, 14, and 28 for evaluation of changes in symptoms, endoscopy, and monitoring of any adverse reactions. Demographics, clinical characteristics and drug efficacy were also compared between the two groups. RESULTS: Among the 60 initially enrolled patients (CP 30, AMC 30), 5 patients in the CP group and 6 in the AMC group were excluded due to poor compliance. There were no significant differences in demographic data including age, sex, initial signs and symptoms, endoscopic and X-ray findings between the two groups. Rates of improvement after 2 weeks were 96% and 95.8% in the CP and AMC group, respectively. Sinus symptoms were changed significantly after 2 and 4 weeks, however, there was no difference between groups (P=0.41). The most common adverse reaction was gastrointestinal complication, diarrhea occurred in 1 patient in the CP group and 6 in the AMC group (P=0.04). CONCLUSION: CP and AMC were both effective in treating ARS. The difference of treatment outcome was not found between the two groups, however, gastrointestinal complications were less prevalent in the CP group.

Langerhans cell histiocytosis(LCH) is a systemic disorder characterized by idiopathic proliferation of histiocytes in the reticuloendothelial system; CNS involvement outside the hypothalamus or pituitary gland is uncommon. We present a case of LCH involving the brainstem, cerebellum, and temporal lobes, and also showing hypothalamic involvement. The lesions were isointense or hypointense on T1WI and hyperintense on T2WI, and showed multifocal enhancing nodules on post-contrast CT and Gd-enhanced MRI.

The thoracic spine is rigidly stabilized by the ribs, anterior and posterior longitudinal ligaments, and a sagittal orientation of the facet joints that resists axial rotation and horizontal translation. Thus, a significant force is required to cause a fracture and dislocation in the thoracic spine. A 32-year-old man was involved in a motor-vehicle accident and presented with complete paraplegia and spondyloptosis on the 8th thoracic vertebral segment. He also suffered with hypoxia and hypovolemic shock. Posterior reduction and fixation with pedicle screw was achieved with the anatomic alignment and rigid stability. This posterior technique for thoracic spondyloptosis is believed to be sufficient to make good alignment and solid fixation.
