OBJECTIVE Supracricoid laryngectomy (SCL) with Cricohyoidoepiglotto-pexy (CHEP) or Cricohyoido-pexy (CHP) is an organ preservation surgery indicated for early and selected advanced laryngeal cancers. To verify the clinical usefulness of supracricoid laryngectomy versus total laryngectomy, a retrospective review was conducted. METHODS We summarized the(More)
We present two cases of superficial squamous cell carcinoma of the floor of the mouth, which were coincidentally detected by narrow band imaging (NBI) combined with magnifying gastrointestinal endoscopy (GIE) during gastrointestinal evaluation. We successfully removed the lesions using laser assisted with NBI combined with magnifying GIE. Because NBI(More)
The objectives of surveillance after endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) for esophageal squamous cell carcinoma are: (i) early detection and treatment of recurrence; and (ii) early detection and treatment of metachronous esophageal squamous cell carcinoma and second primary cancers. Protocols for follow up after EMR(More)
OBJECTIVES Among the 50 laryngeal cancer patients who received SCL-CHEP between 1997 and 2008, we experienced three patients with complete epiglottis prolapse, which obstructed the neoglottis. By defining this complication as "Inverted epiglottis" and presenting the clinical features, we intend to elucidate the mechanism, risk factors, and management of(More)
BACKGROUND Instrumentation and fusion to the sacrum/pelvis has been a mainstay in the surgical treatment of scoliosis in patients with Duchenne muscular dystrophy since the development of the intrailiac post. It is recommended for correcting pelvic obliquity. However, caudal extent of instrumentation and fusion has remained a matter of considerable debate.(More)
OBJECTIVES Supracricoid laryngectomy (SCL) is a reliable laryngeal preservation surgery. However, close surgical margins are often inevitable. Based on clinicopathological analyses of supracricoid laryngectomized specimens, we evaluated the evidence base supporting minimal margins. METHODS The distance between tumor edge and resected margin was measured(More)
In a previous study, the authors reported the clinical and radiological results of Duchenne muscular dystrophy (DMD) scoliosis surgery in 14 patients with a low FVC of <30%. The purpose of this study was to determine if surgery improved function and QOL in these patients. Furthermore, the authors assessed the patients' and parents' satisfaction. %FVC(More)
OBJECTIVES/HYPOTHESIS Multicentric squamous dysplasia in the esophagus can be visualized by Lugol chromoendoscopy as multiple Lugol-voiding lesions (LVLs). Narrow-band imaging combined with magnifying endoscopy (NBI-ME) facilitates the detection of superficial squamous cell carcinoma within the head and neck region (HNSCC). We investigated risk factors for(More)
OBJECTIVE Cervical nodal metastasis from clinically undetectable primary squamous cell carcinoma (SCC) accounts for 1-2% of head and neck malignancies. We retrospectively evaluate the ability of Narrow band imaging combined with magnifying endoscopy (NBI-ME) to detect the primary sites of superficial SCC in the head and neck region. METHODS This was a(More)
OBJECTIVE The conventional surgical method for a case of unilateral laryngeal nerve paralysis with large glottal gap requires an external cervical incision. In the present study, we developed an endoscopic technique of vocal fold medialization that can make the external incision unnecessary. This procedure of autologous transplantation of fascia into the(More)
