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

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.

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.

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.

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.

We present a case of an athetoid cerebral palsy with quadriparesis caused by kyphotic deformity of the cervical spine, severe spinal stenosis at the cervicomedullary junction, and atlantoaxial instability. The patient improved after the first surgery, which included a C1 total laminectomy and C-arm guided righ side unilateral C1-2 transarticular screw fixation. C1-2 fixation was not performed on the other side because of an aberrant and dominant vertebral artery (VA). Eight months after the first operation, the patient required revision surgery for persistent neck pain and screw malposition. We used intraoperative VA angiography with simultaneous fluoroscopy for precise image guidance during bilateral C1-2 transarticular screw fixation. Intraoperative VA angiography allowed the accurate insertion of screws, and can therefore be used to avoid VA injury during C1-2 transarticular screw fixation in comorbid patients with atlantoaxial deformities.

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.

OBJECTIVE: At present, gold-standard technique of cervical cord decompression is surgical decompression and fusion. But, many complications related cervical fusion have been reported. We adopted an extended anterior cervical foraminotomy (EACF) technique to decompress the anterolateral portion of cervical cord and report clinical results and effectiveness of this procedure. METHODS: Fifty-three patients were operated consecutively using EACF from 2008 to 2013. All of them were operated by a single surgeon via the unilateral approach. Twenty-two patients who exhibited radicular and/or myelopathic symptoms were enrolled in this study. All of them showed cervical cord compression in their preoperative magnetic resonance scan images. RESULTS: In surgical outcomes, 14 patients (64%) were classified as excellent and six (27%), as good. The mean difference of cervical cord anterior-posterior diameter after surgery was 0.92 mm (p<0.01) and transverse area was 9.77 mm2 (p<0.01). The dynamic radiological study showed that the average post-operative translation (retrolisthesis) was 0.36 mm and the disc height loss at the operated level was 0.81 mm. The change in the Cobb angle decreased to 3.46, and showed slight kyphosis. The average vertebral body resection rate was 11.47%. No procedure-related complications occurred. Only one patient who had two-level decompression needed anterior fusion at one level as a secondary surgery due to postoperative instability. CONCLUSIONS: Cervical cord decompression was successfully performed using EACF technique. This procedure will be an alternative surgical option for treating cord compressing lesions. Long-term follow-up and a further study in larger series will be needed.
