In narrow band (NB) laryngeal endoscopy, the clinician usually positions the endoscope near the tissue for a correct inspection of possible vascular pattern alterations, indicative of laryngeal malignancies. The video is usually reviewed many times to refine the diagnosis, resulting in loss of time since the salient frames of the video are mixed with blurred, noisy, and redundant frames caused by the endoscope movements. The aim of this work is to provide to the clinician a unique larynx panorama, obtained through an automatic frame selection strategy to discard non-informative frames...

BACKGROUND: Multi-step cancerogenesis guides laryngeal cancer onset and it includes a wide variety of pre-cancerous lesions macroscopically challenging to identify and distinguish from initial cancerous foci. OBJECT: Different modalities of diagnostic techniques of laryngeal epithelial lesions exist and they do not offer a single system to make a differential diagnosis. Hence, this meta-analysis aimed to synthesize the validity of each single diagnostic tool to improve laryngeal patient management...

In the cases of uncertainty, even if the patient has no complaints about his voice quality, sometimes, benign vocal fold mass lesions are removed to exclude malignancy with the risk of resultant dysphonia. Narrow Band Imaging (NBI) enables a specific visualization of vessel structures in the superficial tissue. Benign lesions of the larynx are frequently characterized by abnormal vessel configuration or an absence of vessels in the area of the lesion. It was hypothesized that, in the primary diagnosis of patients with these benign lesions, the combination of white light and NBI endoscopy enables a better detection compared with white light endoscopy alone...

OBJECTIVES/HYPOTHESIS: Direct suspension laryngoscopic biopsy performed under general anesthesia is the conventional management for obtaining pathological diagnosis for neoplasms of the larynx, oropharynx, and hypopharynx. Since the development of distal chip laryngoscopy and digital imaging systems, transnasal flexible laryngoscopy tissue sampling has gained popularity as an office-based procedure. Additional assessment with narrow-band imaging (NBI) can help to increase the diagnostic yield...

Endoscopy is essential for the diagnosis and treatment of cancers derived from the larynx. However, a laryngoscope with conventional white light (CWL) has technical limitations in detecting small or superficial lesions on the mucosa. Narrow band imaging especially combined with magnifying endoscopy (ME) is useful for the detection of superficial squamous cell carcinoma (SCC) within the oropharynx, hypopharynx, and oral cavity. A total of 3675 patients who have come to the outpatient clinic and complained of inspiratory stridor, dyspnea, phonation problems or foreign body sensation, were enrolled in this study...

OBJECTIVES: Patients with head and neck squamous cell carcinoma (HNSCC) often develop second primary tumors in the upper aerodigestive tract. Early detection of synchronous esophageal squamous cell neoplasm (ESCN) is important because the prognosis of HNSCC can be affected by the statuses of second primary tumors. METHODS: In a prospective study, 308 patients with HNSCC were screened for synchronous ESCN between May 2010 and April 2012. All patients underwent conventional white-light endoscopic examination with Lugol chromoendoscopy and narrow band image...

BACKGROUND: The larynx and hypopharynx are common sites for head and neck cancer, which shares many risk factors with upper digestive tract disease. Patient survival with malignancies depends on stage at the time of diagnosis. Endoscopic screening of the hypopharynx is neither routinely performed in clinical practice nor has it been evaluated in a formal study. METHODS: This is a prospective pilot study of patients undergoing routine EGD. Demographic data were collected from patients prior to the procedure...

Narrow band imaging is considered a significant improvement in the possibility of detecting early mucosal lesion of the upper aerodigestive tract. Early detection of mucosal neoplastic lesions is of utmost importance for patients survival. There is evidence that, especially in patients previously treated by means of curative radiotherapy or chemoradiotherapy, the early detection rate of recurrent disease is quite low. The aim of this study was to prove whether the videoendoscopy coupled with NBI might help detect recurrent or secondary tumors of the upper aerodigestive tract...

BACKGROUND AND OBJECTIVES: Autofluorescence (AF) techniques improve the diagnostic yield of white light inspection for preneoplastic lesions in the bronchus and head and neck region. Although highly sensitive, AF has poor specificity, particularly in situations where there have been earlier biopsies or treatments such as radiotherapy. Narrow band imaging (NBI) is a newer imaging technique that enhances the early abnormal angiogenesis seen in preneoplastic lesions. NBI has higher specificity when compared with AF...

UNLABELLED: Voice quality disorders--dysphonias are the significant problem from therapeutic, social and economic point of view. The routine therapy does not always bring spectacular effects. The important role play the innovative methods supporting therapy of voice quality disorders. PURPOSE: The aim of the study is to assess the effects of vibratory therapy of the larynx (Medical VR) in patients with hyperfunctional dysphonia and stimulating currents in phonatory exercises (VocaStim-Master) in paralytic dysphonia based on the analysis of parameters of objective assessment of voice quality...

PURPOSE OF REVIEW: Narrow band imaging (NBI) is a novel endoscopic technique using filtered wavelengths in order to enhance the microvascular abnormalities associated with the preneoplastic and neoplastic changes of the mucosal lining of the upper aerodigestive tract. The present review is focused on the use of NBI in the management of patients with laryngeal cancer. RECENT FINDINGS: The larynx and hypopharynx represent an ideal site for NBI application because their thin, nonkeratinized, stratified squamous epithelium permits optimal visualization of the subtle neoangiogenic changes associated with precancerous and neoplastic diseases, including benign processes like recurrent respiratory papillomatosis...

Direct suspension laryngoscopic biopsy of neoplasms in larynx, oropharynx, and hypopharynx was an arduous procedure in patients with a history of head and neck cancer and difficult airways. This preliminary study was aimed to report the efficacy and safety of a narrow band imaging-guided biopsy of this category by flexible laryngoscopy. This is a retrospective chart review study conducted in setting of tertiary referral centre. Nineteen consecutive head and neck cancer patients with difficulty in general anesthesia and rigid endoscopic approach due to trismus, craniofacial deformities, and/or limited neck extension after cancer therapy were referred for endoscopic biopsy of their suspicious lesions in larynx, hypopharynx, or parts of oropharynx...
