Olfaction is an important aspect of quality of life, beyond simply smelling food and recognizing danger. Recently, research has focused on its association with various diseases, such as neurodegenerative diseases or viral infections. The evaluation of olfactory function must take into consideration the cultural experience of the target group. A new Korean culturefriendly olfactory function test, the YSK olfactory function test (YOF test, Kimex Co.), uses safe odorants, such as phenyl-ethyl alcohol (PEA) (not n-butanol), for the threshold test. Furthermore, odorants in the YOF identification test reflect each of eight major chemical functional groups. The diagnostic cut-off for anosmia was a Threshold Discrimination Identification (TDI) score of ≤14.5 and that for hyposmia was 14.5

Laryngeal trauma is rare compared to other head and neck traumas, but it occurs, it can be life threatening. As for treatment, a laryngeal fracture that involves displacement of cartilage or extensive injury requires appropriate surgical treatments. For severe laryngeal fractures, conservative management is usually preferred with placing a stent to prevent laryngeal stenosis. But the downside of placing stents in the larynx includes the risk of granulation and infection. In this report, the authors describe a 35-year-old patient, who was diagnosed with blunt laryngeal trauma and treated by Horizontal partial laryngectomy. The patient's post-operative breathing and voice were fair, and airway stenosis did not occur afterwards.

Mucormycosis is one of the most fatal and rapidly progressive fungal infections in humans; among its many forms. rhinocerebral mucormycosis is the most common. It is known to occur as opportunistic infection in patients with uncontrolled diabetes, metabolic disorders, organ transplantation, or autoimmune disease with prolonged steroid use. Pott’s puffy tumor is the subperiosteal abscess of the frontal bone caused by trauma complication or frontal sinusitis. It is considered as a very rare complication since the dawn of antibiotic treatments. We report a case of chronic rhinocerebral mucormycosis involving Pott’s puffy tumor in a patient receiving immunosuppressive therapy after lung transplantation.

While simultaneous bilateral partial nephrectomy with a conventional multiport robot has been consistently reported since the 2010s, the introduction of the DaVinci SP system (Intuitive Surgical, Sunnyvale, CA, USA) could provide a novel way to perform surgery on bilateral kidneys while innovatively reducing the number of incisions. In our first report worldwide, the patient with bilateral small renal mass (2.0 cm for the left and 1.5 cm for the right side) and preoperative normal renal function was placed in the lateral decubitus position on an inverted bed. After tilting the bed to be as horizontal as possible, a 4-cm incision was made in the lower part of the umbilicus for the floating trocar technique. The partial nephrectomy was performed reliably as with the conventional transperitoneal approach, and then the patient could be repositioned to the contralateral side for the same procedure, maintaining all trocars. Total operation time (skin to skin), total console time, and the left- and right-side warm ischemic times were 260, 164, 27, and 23 minutes, respectively, without applying the early declamping technique. The estimated blood loss was 200 mL. The serum creatinine right after the operation, on the first day, 3 days, and 90 days after surgery were 0.92, 0.77, 0.79, and 0.81 mg/dL, respectively. For 90 days after the procedure, no complications or radiologic recurrence were observed. Further clinical studies will reveal the advantages of using the DaVinci SP device for this procedure over traditional multiport surgery, maximizing the benefit of a single port-based approach.

OBJECTIVE: We previously reported excellent early and midterm clinical results of anterior cervical microforaminotomy (ACMF) for patients with cervical radiculopathy caused by disc herniation or foraminal stenosis. ACMF is accepted as a minimally invasive functional spinal surgery, but its long-term outcomes are unknown. The purpose of this study is to evaluate the long-term clinical and radiographic results of ACMF. METHODS: We performed a questionnaire survey and retrospective analysis of 13 patients with cervical radiculopathy who underwent ACMF from 1998 to 2002. Clinical and radiographic data from these 13 patients (one-level operations in seven patients, and two-level operations in six patients) were analysed. We measured disc height, sagittal plane displacement and sagittal plane angulation to evaluate instability. RESULTS: Thirteen patients answered the questionnaires. Mean follow-up was 77.3 months (ranged from 498 to 110 months). The surgical outcome was excellent in three patients (23%) and good in nine patients (69%). One patient had only a fair outcome, but there were no cases of recurrence, reoperation or additional surgery. Twelve of 13 patients were satisfied with the results of their surgery. On the average, the loss of disc height was 0.84mm(16.6% of preoperative disc height), increase of displacement was 0.47mm and increase of sagittal plane angulation was 0.65degrees. All patients maintained stability during the follow-up period. Although the patient sample included in this study is a different sample from that surveyed in our previous study of mid-term results, the long-term radiographic outcomes showed that the parameters of instability tended to decrease in comparison to those midterm results. Three-dimensional computed tomography scans showed signs indicative of bone remodeling, including regrowth of the resected bone and gradual fusion around the uncovertebral joint (UVJ) where ACMF was performed. In spite of bone regeneration around the UVJ, the neural foramen appeared to be well maintained in all patients. CONCLUSION: In the long-term, ACMF is clinically effective method for the treatment of cervical radiculopathy, although disc height was decreased and sagittal angulation was increased. UVJ with mild hypermobility that was apparent at midterm appears to be restored during long-term follow-up. The efficacy of this procedure should be evaluated in additional studies involving large patient series.

The authors report a case of syringo-pleural shunt for recurrent distal obstruction of syringosubarachnoid shunt in a 23-year-old woman. She complained of tingling sensation and dysesthesia on the left upper extremity. Neuroradiologic imaging studies revealed syringomyelia in the left lateral side of the cord from medulla to 7th thoracic cord level. We identified intraoperatively high internal pressure of the syrinx cavity due to distal shunt tube obstruction. Syringo-pleural shunt was performed and cavity size was markedly decreased at later follow up MRI. In conclusion, the posttraumatic syrinx, especially in cases with previous syringosubarachnoid shunt or diffuse subarachnoid scarring, can be successfully managed with syringo-pleural shunt.

The authors present a case of malignant cystic meningioma in the left frontal convexity. The patient was 80-year-old male and presented with personality change and walking difficulty. Computerized tomography and magnetic resonance image demonstrated a round mass attached to the left frontal convexity dura. Intratumoral and peritumoral cystic lesions were also seen. Total removal of tumor was performed and the histological dia-gnosis was anaplastic meningioma.

OBJECTIVE: The purpose of this study was to assess long-term clinical outcomes and radiographic changes in patients with lumbar spinal stenosis with grade I degenerative spondylolisthesis who underwent microsurgical bilateral decompression via unilateral laminotomy, as a minimally invasive surgery. Method: Medical records of twenty-five patients who underwent the surgery between 1999 and 2005 were retrospectively evaluated. Clinical outcomes were evaluated through interviews over telephone with standardized questionnaires. Preoperative and postoperative radiographs were taken from all patients in neutral and dynamic lateral views. The mean follow-up period after surgery was 38.5 months(range 9-57 months). RESULTS: Seventy-two percent of patients were either pain free(48%) or doing well with occasional acetaminophens(24 %), and satisfied with the treatment. The most improved preoperative symptom was neurogenic intermittent claudication, which was ameliorated in 94.7% of patients(excellent 84.2%, good 10.5%, fair 5.3%). Postoperative vertebral slippage was also measured and appeared to be slightly increased but this was not statistically significant. Postoperative dynamic angulation did not change significantly compared to the preoperative value. CONCLUSION: Microsurgical bilateral decompression via unilateral laminotomy achieved a satisfactory decompression and symptomatic relief without extensive destruction of the weight-bearing structures and functional mobile segments. This treatment can be an effective modality for patients with lumbar spinal stenosis associated with mild degenerative spondylolisthesis.
