The posterior superior alveolar artery (PSAA) is a branch of the maxillary artery that supplies blood to the lateral wall of the sinus and the overlying membrane. It is located in the lateroposterior wall of the maxillary sinus and is almost intra-osseous, making surgeries there challenging for the risk of injury during routine endoscopic sinus surgery (ESS). Indeed, there is approximately 20% risk of damage in situations such as Le Fort I fracture surgery, maxillary sinus expansion, removal of lesions and inflammation in the maxillary sinus, surgical procedures involving orthognathic surgery and dental implant treatment, as well as in occurrences of fractures and fenestration during surgery, potentially leading to significant bleeding. We present a rare case of facial hematoma due to PASS injury following ESS, with subsequent improvement and no additional complications after treatment.

STUDY DESIGN: A noninterventional, multicenter, cross-sectional study. PURPOSE: We investigated the prevalence of neuropathic pain (NP) and patient-reported outcomes (PROs) of the quality of life (QoL) and functional disability in Korean adults with chronic low back pain (CLBP). OVERVIEW OF LITERATURE: Among patients with CLBP, 20%–55% had NP. METHODS: Patients older than 20 years with CLBP lasting for longer than three months, with a visual analog scale (VAS) pain score higher than four, and with pain medications being used for at least four weeks before enrollment were recruited from 27 general hospitals between December 2014 and May 2015. Medical chart reviews were performed to collect demographic/clinical features and diagnosis of NP (douleur neuropathique 4, DN4). The QoL (EuroQoL 5-dimension, EQ-5D; EQ-VAS) and functional disability (Quebec Back Pain Disability Scale, QBPDS) were determined through patient surveys. Multiple linear regression analyses were performed to compare PROs between the NP (DN4≥4) and non-NP (DN4 < 4) groups. RESULTS: A total of 1,200 patients (females: 65.7%; mean age: 63.4±13.0 years) were enrolled. The mean scores of EQ-5D, EQ-VAS, and QBPDS were 0.5±0.3, 55.7±19.4, and 40.4±21.1, respectively. Among all patients, 492 (41.0%; 95% confidence interval, 38.2%–43.8%) suffered from NP. The prevalence of NP was higher in male patients (46.8%; p < 0.01), in patients who had pain based on radiological and neurological findings (59.0%; p < 0.01), and in patients who had severe pain (49.0%; p < 0.01). There were significant mean differences in EQ-5D (NP group vs. non-NP group: 0.4±0.3 vs. 0.5±0.3; p < 0.01) and QBPDS (NP group vs. non-NP group: 45.8±21.2 vs. 36.3±20.2; p < 0.01) scores. In the multiple linear regression, patients with NP showed lower EQ-5D (β=−0.1; p < 0.01) and higher QBPDS (β=7.0; p < 0.01) scores than those without NP. CONCLUSIONS: NP was highly prevalent in Korean patients with CLBP. Patients with CLBP having NP had a lower QoL and more severe dysfunction than those without NP. To enhance the QoL and functional status of patients with CLBP, this study highlights the importance of appropriately diagnosing and treating NP.

Infestation of tissue by fly larvae is termed myiasis, and it is unusual in humans. Nasal myiasis is common in low socioeconomic status individuals due to poor nasal hygiene. It commonly affects the skin and rarely the nasal and paranasal sinuses. Recently an 82-year-old female was admitted to the emergency department because of discharge of live maggots from the nasal cavity. She had been diagnosed with brain infarction and Alzheimer's disease several years previous. We successfully removed all the maggots from the patient's nasal cavity and sinuses via endoscopic surgery under local anesthesia. Subsequently, the patient's nasal problem resolved completely.

Fibrous dysplasia is a benign pathological condition of bone in which fibrous tissue gradually expands and replaces normal bone. Histologically, it shows various degrees of osseous metaplasia. Fibrous dysplasia frequently affects the maxilla, frontal bone, and mandible. The sign and symptoms of fibrous dysplasia of head and neck vary and are related to the location and extent of bony abnormalities. Facial asymmetry is the most common sign of fibrous dysplasia, while pain and ocular proptosis are the next most frequent symptoms. Fibrous dysplasia is rare in the nasal cavity, especially involving the turbinate and nasal septum. So we report a case of fibrous dysplasia, which extensively involves the middle turbinate and nasal septum, with a review of literature.

BACKGROUND AND OBJECTIVES: The purpose of this study was to share our clinical experience on the use of bioresorbable poly L-/DL-lactide 70/30 implant to repair blow out fracture. SUBJECTS AND METHOD: The medical records of 130 patients with orbital fractures that were treated surgically from June 2006 to February 2011 were reviewed retrospectively. Patients who had diplopia or limited extraocular motion, significant Enophthalmos (>2 mm), or a large orbital wall fracture on a computed tomographic scan were enrolled for the study. We investigated diplopia, limited extraoacular motion, enophthalmos before and after surgery. RESULTS: The mean postoperative follow-up was 28 months. There was no evidence of sinus infection related to the implant. However, six patients showed dislocation of orbital implant in the nasal cavity. After six postoperative months, diplopia was seen in 1 (2%) patient, and significant enophthalmos was seen 2 (2%) patients. We carried out re-operation on six cases and the main cause was incomplete reduction or over reduction. CONCLUSION: Bioresorbable poly L-/DL-lactide 70/30 implants are safe and reliable for the reduction for blowout fracture.

PURPOSE: The purpose of this study was to evaluate the clinical effect of electrocautery on the reduction of pain in patellar non-resurfacing bilateral total knee arthroplasty. MATERIALS AND METHODS: A total of 50 patients were enrolled into this study; all patients had undergone bilateral patellar non-resurfacing total knee arthoplasty at our hospital, between January 2007 to December 2008. The minimum follow-up period was 1 year. The electrocautery of the patellar rim was performed randomly on one side only. The clinical results were evaluated between the electrocautery group and the non-electrocautery group based on measures of anterior knee pain, range of motion, American Knee Society clinical rating score, Feller knee score, Western Ontario and McMaster Universities score, and radiographic analysis. RESULTS: There were statistically significant differences between preoperative and postoperative status for all parameters. There were no statistically significant differences noted between the electrocautery group and the non electrocautery group for all parameters. CONCLUSIONS: Electrocautery of patellar rim is thought to be less effective in reducing anterior knee pain.
