Lasers in laryngeal surgery

The use of lasers in laryngology has evolved over the last several decades. With improving optics, instrumentation, and applications for treatment, lasers are now routinely used during laryngeal surgery performed in both the operating room and clinic settings. A variety of laser types, including carbon dioxide (CO2), potassium titanyl-phosphate (KTP), and pulsed-dye lasers, are used to treat an array of benign laryngeal lesions. Otolaryngologists can now consider the use of lasers to treat benign vocal fold lesions including vocal fold polyps, varices/ectasias, scar, granulomas, recurrent respiratory papillomatosis, Reinke's edema, and nodules, among others.

Publication date: Available online 29 November 2019Source: Saudi Journal of Biological SciencesAuthor(s): Kahkashan Perveen, Najat A. BokahriAbstractThree important varieties of dates (Sukri, Barhi, and Rothana), grown in Saudi Arabia were analyzed for their chemical, mineral and anti-bacterial activity. Among all the varieties analyzed, the Sukri dates had the highest moisture (16%), carbohydrate (80.65 mg/g) and the phenolic content (1.24 mg GAE/100 g) whereas, the ash content was the lowest (2.22%). The mineral content analyzed by ICP OES reveals that all three varieties contain an appreciable amount of e...

Conclusion: Autoimmune encephalitis is not uncommon in patients with acute psychosis. Elevated WBC counts, certain prodromal features, and a more severe illness at presentation should prompt appropriate evaluation.

AbstractObjectiveThe aim of this study was to compare narrow band imaging (NBI) endoscopy and Storz Professional Image Enhancement System (SPIES) in observing epithelial and/or subepithelial microvascular irregularities and pathologies.MethodsA total of 73 patients with laryngeal or hypopharyngeal lesions were investigated using high-definition NBI endoscopy preoperatively in local anesthesia and using SPIES system intraoperatively in general anesthesia from August 2016 to October 2017. Superficial vascular structures were classified preoperatively (NBI) and intraoperatively (SPIES) according to descriptive guidelines of v...

A 23-year-old woman presented to the clinic with complaints of heartburn and dysphagia with solid foods. Her family history was remarkable for gastric and  lung cancer in first-degree relatives. Her physical examination and routine laboratory study results were normal. An upper endoscopy was performed and showed multiple polypoid lesions ranging in size from 3 to 11 mm, involving the entire esophagus (Figure A; Video). An endoscopic polypectomy of se veral of the larger polyps was performed. Histopathologic examination showed the lesions were squamous papillomas with areas of hyperkeratinization.

CONCLUSION: MLD may be associated with a spectrum of gallbladder pathology including neoplastic conditions. Pathologists and clinicians should be aware of this association/risk. The patient may be offered regular ultrasound screening of the gallbladder. PMID: 29494779 [PubMed - as supplied by publisher]

A 71-year-old woman presented with dysphagia 2 years after undergoing radical chemoradiotherapy for squamous cell carcinoma of the cervical esophagus. Endoscopy revealed a benign esophageal stricture 20 cm from the incisors, with a 1-cm villiform mass below the stricture (A). The esophageal mass increased in size over the next  4 years, completely obstructing the lumen (B) and extending over a length of 12 cm as shown by contrast swallow (C). Examination of multiple sets of biopsy specimens failed to show any evidence of atypia, high-grade dysplasia, or invasive malignancy, but histologic analysis did show multiple po...

Abstract The advancement of lasers and optics over the last half of the twentieth century has enabled the otolaryngologist to visualize and treat many diseases heretofore treated only in the operating room. The laryngologist, specifically, can now use fiber-based lasers and thin working channel scopes to diagnose and treat many laryngologic conditions in the office. Pulsed-dye lasers and potassium titanyl phosphate lasers are utilized to treat granulomas, polyps, recurrent respiratory papillomatosis, airway stenosis, reinke’s edema, leukoplakia, and vascular lesions without the need for general anesthesia or...

Authors: Uloza V, Liutkevicius V, Pangonyte D, Lesauskaite V Abstract OBJECTIVES: The aim of this study was to investigate expression profile of matrix metalloproteinases (MMP-2 and MMP-9) in glottic squamous cell carcinoma (SCC) and benign vocal fold lesions (BVFLs) and to correlate it with clinical and pathological features. METHODS: The immunohistochemical expression of MMP-2 and MMP-9 was investigated in specimens taken from 217 patients group, including vocal fold polyps (n=39), recurrent respiratory papillomatosis (n=30), laryngeal keratosis (n=36), glottic SCC (n=112), and the normal tissue of vocal fold...
