A meaningful proportion of HJB ears had bony dehiscence contact with the tympanic membrane. In planning ear surgery and other interventions, physicians should keep in mind the possibility of HJB and its bony dehiscence, which can lead to inadvertent injuries.

The purpose of this study was to evaluate and compare the diagnostic efficacy of ultrasonography (US) with radiography and multi-detector computed tomography (CT) for the detection of nasal bone fractures. Forty-one patients with a nasal bone fracture who underwent prospective US examinations were included. Plain radiographs and CT images were obtained on the day of trauma. For US examinations, radiologist used a linear array transducer (L17-5 MHz) in 24 patients and hockey-stick probe (L15-7 MHz) in 17. The bony component of the nose was divided into three parts (right and left lateral nasal walls, and midline of nasal bone). Fracture detection by three modalities was subjected to analysis. Furthermore, findings made by each modality were compared with intraoperative findings. Nasal bone fractures were located in the right lateral wall (n = 28), midline of nasal bone (n = 31), or left lateral wall (n = 31). For right and left lateral nasal walls, CT had greater sensitivity and specificity than US or radiography, and better agreed with intraoperative findings. However, for midline fractures of nasal bone, US had higher specificity, positive predictive value, and negative predictive value than CT. Although two US evaluations showed good agreements at all three sites, US findings obtained by the hockey-stick probe showed closer agreement with intraoperative findings for both lateral nasal wall and midline of nasal bone. Although CT showed higher sensitivity and specificity than US or radiography, US found to be helpful for evaluating the midline of nasal bone. Furthermore, for US examinations of the nasal bone, a smaller probe and higher frequency may be required.

Conclusions: A method was created and validated to determine the optimal surgical approach and pathway geometry for accessing a specific target pathology. It was robust and is applicable to many clinical scenarios. Initial evaluation in surgical cases has begun.Objectives: The most common chemoradiotherapy regimen is high-dose (100mg/m2) three-weekly cisplatin with concomitant radiotherapy; however, this protocol is associated with acute and late toxicities. Recent study demonstrated that human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) patients showed good prognosis. We reviewed the efficacy for concomitant weekly cisplatin and radiotherapy in patients with HPV-positive OPSCC.Methods: Twenty-two patients with untreated OPSCC were enrolled and evaluated at our institution from July 2006 to June 2012. Weekly cisplatin (40mg/m2) was given on weeks 1,2,3,5,6 and 7 with radiotherapy, which comprised a standard dose of 70 Gy delivered in 35 daily fractions over 7 weeks. The presence of HPV was analyzed using multiplex PCR method. Median follow-up time was 26 months for surviving patients.
