Numerous advances have recently been made in endoscopy for both diagnosis and treatment of gastrointestinal diseases. However, these advances have taken little account of the small bowel, as access by endoscopy is often difficult. With the advent of push endoscopy in 1971, the proximal jejunum could be examined to about 50 cm from the ligament of Treitz. The subsequent introduction of videoendo...

Salivary gland toxicity is a common adverse effect of radioactive iodine (131I) for the treatment of thyroid cancers with a prevalence ranging from 2% to 67% of the 131I exposed population. Recently, sialendoscopy has been introduced as an attractive diagnostic and therapeutic tool for management of patients with radioiodine-induced sialadenitis that is unresponsive to standard medical treatmen...

OBJECTIVES Although near-normal conversational voices can be achieved with the phonosurgical management of early glottic cancer, there are still acoustic and aerodynamic deficits in vocal function that must be better understood to help further optimize phonosurgical interventions. Stroboscopic assessment is inadequate for this purpose. METHODS A newly developed color high-speed videoendoscopy...

During bronchoconstriction elastic after-loads arise due to distortion of lung parenchyma by the narrowing airway. In the present study, the functional effect of parenchymal elastic after-load on airway narrowing was determined. Airway narrowing was measured in vivo over a range of transpulmonary pressures and compared with in vitro narrowing measured at corresponding transmural pressures. Bron...

PURPOSE To describe a technique of endoscopic harvesting of autogenous fascia lata. METHODS A retrospective, noncomparative clinical study to evaluate the technique of videoendoscope assistance in harvesting autogenous fascia lata was conducted during a 1-year period in 2002. A small incision approximately 2 cm long is made over the lateral aspect of the thigh, either as a low or high approac...

PURPOSE The aim of the article was to introduce a new subantroscopic laterobasal sinus augmentation (SALSA) tecnique as a minimally invasive approach to maxillary peri-implant surgery. MATERIALS AND METHODS The SALSA technique consists of the following steps: (1) microsurgical opening of the subantral space (SAS) with detachment of the sinus membrane (SM) under supported videoendoscopy; (2) e...

BACKGROUND Postoperative irrigation after endoscopic sinus surgery and endoscopic modified Lothrop procedure is used to remove nasal crusts and to improve wound healing. To evaluate the optimal application protocol for irrigation of the frontal sinus, a prospective cadaver study was performed. METHODS An endoscopic modified Lothrop procedure and complete sphenoethmoidectomy were performed in ...

OBJECTIVES There is increased interest in using cepstral-based acoustic measures for objective clinical voice assessment because of their apparent advantages over more time-honored methods, but there is a paucity of information about how these newer measures relate to underlying phonatory mechanisms. METHODS We investigated the relationships between the acoustic cepstral peak magnitude (CPM) ...

Different source-related factors can lead to vocal fold instabilities and bifurcations referred to as voice breaks. Nonlinear coupling in phonation suggests that changes in acoustic loading can also be responsible for this unstable behavior. However, no in vivo visualization of tissue motion during these acoustically induced instabilities has been reported. Simultaneous recordings of laryngeal ...
