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.

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.

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: 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.

OBJECTIVE: We have previously reported excellent early clinical results of anterior cervical microforaminotomy(ACMF) for patients who have cervical radiculopathy from either disc herniation or foraminal stenosis. ACMF is being accepted as a minimal invasive functional spinal surgery, but their long-term outcome is unknown. The goal of this study is to evaluate the midterm clinical and radiological results of ACMF. METHODS: We had undertaken a questionnaire survey and retrospective analysis of 42 patients with cervical radiculopathy who had undergone ACMF from 1998 to 2001. Clinical data from 33 patients(one-level operation in 20 patients, two-level in 13 patients) and radiological data from 21 patients were analysed. RESULTS: Thirty-three patients answered for the questionnaires. Mean follow-up was 48 months(ranged from 26 to 64 months). The surgical outcome was excellent in 18 patients(54.6%) and good in 11 patients(33.3%). One patient showed poor outcome, but there was no case of recurrence, reoperation or additive surgery. Twenty-four patients(79%) satisfied with the results of their surgery. On the average, the loss of disc height was 1.02mm(18% of preoperative disc height), average increase of displacement was 0.83mm, decrease of sagittal plane angulation was 2.03 degrees. All the patients maintained stability during follow-up period. CONCLUSION: In the midterm, ACMF appears to be safe and effective method for the treatment of cervical radiculopathy. To prevent disc height loss and retrolisthesis, skilled disc-preserving technique of ACMF is required and modified technique preserving anterior part of uncovertebral joint may be advantageous.

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.

OBJECTIVE: The aims of this study are to review the incidence of cerebrospinal fluid(CSF) collection complicating the simplified anterior skull base approaches via an eyebrow incision and to identify factors that influence its occurrence and treatment. METHODS: The authors retrospectively analyzed the clinical records and radiologic data of 47 cases(45 patients) who underwent superolateral orbital craniotomy or orbital roof craniotomy via an eyebrow incision at the Eulji Medical Center from September 1998 to August 2002. Forty-three cases were anterior circulation aneurysms and four cases were brain tumors. RESULTS: Significant periorbital CSF collection occurred in 13 cases(11 aneurysms, 2 brain tumors). It was managed with aspiration(8 cases), aspiration and lumbar drainage(2 cases), and dural repair(3 cases). There was no statistically significant difference in operative approaches and patient's characteristics. Periorbital CSF collection occurred in one(16.7%) of six cases using preventive lumbar CSF drainage over two days and in 12 (29.3%) out of 41 cases without it(p>005). CONCLUSION: The authors suggest that careful dissection and water-tight closure of frontal dura, sealing with fibrin glue and compressive dressing of operative wounds are important for the prevention of this complication. However, statistically not significant, preventive lumbar CSF drainage seem to be effective. Aspiration and/or lumbar drainage seem to be sufficient for management of postoperative CSF collection and dural repair could be reserved for refractory cases.
