The fiberoptic bronchoscope is an instrument utilized for visual examination of the bronchi through the procedure of bronchoscopy and may be used to obtain bronchial brushings and biopsies. Mediastinoscopy is the examination of the mediastinum and its lymph nodes, particularly in suspected malignancy. Use of an endoscope to inspect the larynx is laryngoscopy. Thoracoscopy denotes examination of the pleural cavity. Fluoroscopy is a type of radiographic technique that allows visualization of the thoracic contents In a dynamic manner and provides a range of views.

Examination of the larynx, either with a flexible fibreoptic nasendoscope or with a rigid laryngoscope, is necessary for all but the very mildest cases. On endoscopy, an omega-shaped epiglottis, short aryepiglottic folds, redundant arytenoid mucosa and collapse of supraglottic tissues into the laryngeal introitus with inspiration are diagnostic.

Examination of children with stridor should be done by an experienced clinician with care taken not to cause any additional distress to the child. In adults, a flexible laryngoscopy is required for direct visualization of the larynx in most cases. This allows an assessment of the vocal cords themselves, the supraglottis and an overall clinical assessment of the patency of the laryngeal airway.
Effectiveness of C-MAC video-stylet versus C-MAC D-blade video-laryngoscope for tracheal intubation in patients with predicted difficult airway: Randomized comparative study

Recently, video laryngoscopy (VL) has been widely used in cases of difficult intubation as it has shown to produce better visualization of the anatomical airway structures [4,5]. C-MAC VL is introduced by Karl Storz, Tuttlingen in Germany in 1999 [6,7]. It has many merits over the traditional laryngoscope. The advanced optical system and its light source (high intensity light-emitting diodes) led to a clear view of the vocal cord and enabled the operator to overpass the tip of laryngoscope blade to reach into the vallecula under vision [8,9]. C-MAC VL can fit Macintosh blade sizes 2, 3, 4 in addition to other models as Miller sizes 0, 1 and the C-MAC D-Blade [10–12]. The D-blade is highly angulated. Its distal end has greater curvature and faces upward to get the shape of half-moon and these features gave a better view of the glottis and required less cervical spine motion than the conventional one and so it can be used as an alternative blade in difficult airway conditions [13,14].
A novel puncture needle designed for endoscopic keel placement to treat anterior glottic webs

The tailored puncture needle was designed and modified from a maxillary sinus puncture needle in our hospital, which consisted of a needle, an inner core, and a guide (Figures 1(A) and 2(A)). Specifically, we punctured the anterior neck soft tissues into the endolarynx using the needle at first. The inner core was then withdrawn and replaced by the guide (Figure 1(B,C)). A hook was designed on the edge of the guide and could pull the suture out of the laryngeal cavity (Figure 1(C,D)). The surgical procedures were as follows. The laryngeal cavity was exposed under general anesthesia using the suspension laryngoscopy and surgical microscope. The web was incised using a CO2 laser firstly (Figure 2(B)). A reinforced 0.3 mm-thick silicon keel with a 3–0 polypropylene suture passing along was prepared. The puncture needle with its inner core was then inserted into the subglottic cavity (Figure 2(C)), after which the inner core was removed and the catheter sheath was left in place (Figure 2(D)). The guide was introduced into the laryngeal cavity through the catheter sheath subsequently (Figure 2(E)). The distal suture was caught by the hook of the guide and sent outside through the catheter sheath (Figure 2(F)). The proximal suture above the superior thyroid incisurae was sent out by the same approach (Figure 2(G)). The two sutures were tied and secured externally on the anterior neck over a silicone tube after the keel had been placed correctly (Figure 2(H)).
The Impact of Videolaryngoscopy on Endotracheal Intubation Success by a Pediatric/Neonatal Critical Care Transport Team

The studied CCTT chose the C-MAC® videolaryngoscope based on the complete range of pediatric blades sizes allowing use from pre-term infants to adult-sized adolescent patients. In addition, the familiar Miller and Macintosh shaped blades allow the device to be used either as a direct laryngoscope or with the improved view often afforded by a videolaryngoscope. The shared view on the videoscreen also allows a colleague to offer assistance (e.g. external laryngeal manipulation) to the primary laryngoscopist without requiring prompting. In addition to clinical benefit, there are other advantages to the C-MAC® (or other) videolaryngscope that are not specifically addressed in this study. The C-MAC® scope allows intubation attempts to be recorded and later reviewed for educational purposes and to assess performance metrics such as number of attempts and time to intubation and adverse events (28). The use of video review allows for more objective evaluation of procedural performance metrics and has been shown to be more accurate than self-report (29). Given the demonstrated improvement in FPS among pediatric patients and these additional educational and quality assurance benefits, our CCTT continues to utilize the C-MAC® video laryngoscope as first-line equipment for all neonatal and pediatric patients requiring intubation.
