Endolaryngeal surgery of benign vocal fold lesions with a 445 nm semiconductor laser: postoperative management

Introduction. Today the high prevalence of benign vocal fold lesions is shown (up to 55-70%). The possibilities of surgical management of this pathology are very extensive. Laser technologies are becoming more and more popular among high-tech treatment methods. However the comprehensive postoperative management of these patients is equally important.The aim of the study was to assess the features of the postoperative period in patients undergoing the endolaryngeal surgery using a semiconductor laser with a wavelength of 445 nm.Material and methods. On the basis of Saint-Petersburg Research Institute of Ear, Throat, Nose and Speech from February to June 2021 20 patients with benign vocal fold lesions 6 women and 14 men from 24 to 67 years old were examined and treated. All the patients underwent endolaryngeal surgery with direct microlaryngoscopy using a new semiconductor 445 nm laser in an inert gas atmosphere (intraoperative helium supply). After surgical treatment, the patients observed vocal rest, received antiinflammatory, antibacterial therapy, inhalations, as well as the drug Homeovox® according to the standard scheme.Conclusion. Endolaryngeal surgery with the removing of benign vocal fold lesions using a semiconductor laser with a wavelength of 445 nm has been proven to be safe and effective. According to the results of video laryngostroboscopy, acoustic analysis of the voice (the questionnaire “Voice handicap index-30”) it was noted that the laryngeal functions were restored in a short time. The inclusion of Homeovox® in the complex postoperative treatment had a favorable effect on the restoration of the phonatory function.

Vocal outcomes after video assisted cold knife endolaryngeal phonosurgery of benign vocal fold lesions

<p class="abstract"><strong>Background:</strong> This study focuses on therapeutic possibilities in managing benign superficial vocal fold lesions with video assisted cold knife endolaryngeal phonosurgery.</p><p class="abstract"><strong>Methods: </strong>Fifty patients with benign vocal fold lesions presented to us between September 2013 and October 2015 who failed conservative therapy were subjected to video assisted cold knife endolaryngeal phonosurgery. The pre and postoperative results were evaluated based on voice rating by visual analogue scale and GRBAS scale.</p><p class="abstract"><strong>Results</strong>: Encouraging results were achieved with cold knife endolaryngeal surgery as 96.3% of patients were symptom free without any recurrence after single operation. Most of them have achieved &gt;90% of voice outcome by 1 month postoperatively based on voice assessment and laryngoscopic evaluation.</p><p class="abstract"><strong>Conclusions:</strong> Using a telescope with high definition video system for performing phonosurgery is economic, enables the surgeon to acquire static images and video sequences. Cold knife endoscopic laryngeal surgery is possibly a better option for addressing BVFLs.</p>

Consistent Technique Limits Suspension Laryngoscopy Complications

Introduction Suspension laryngoscopy (SL) is a commonly performed procedure among otolaryngologists. Several studies have shown that adverse effects occur regularly with SL. Objective To evaluate the postoperative complications of SL, and to determine if protecting the dentition and the oral mucosa and limiting suspension times decrease the overall incidence of oral cavity and pharyngeal complications of SL. Methods All of the cases of SL performed by 1 surgeon from November 2008 through September 2014 were retrospectively reviewed. A consistent technique for dental and mucosal protection was utilized, and suspension times were strictly limited to 30 consecutive minutes. The incidence of postoperative complications was calculated and analyzed with respect to gender, smoking status, dentition, laryngoscope type, and suspension system. Results A total of 213 consecutive SL cases were reviewed, including 174 patients (94 male, 80 female). The overall postoperative complication rate was of 3.8%. Four patients experienced tongue-related complications, two experienced oral mucosal alterations, one had a dental injury, and one experienced a minor facial burn. The complication incidence was greater with the Zeitels system (12.5%) compared with the Lewy suspension system (3.3%), although it was not significant (p = 0.4). Likewise, the association of complications with other patient factors was not statistically significant. Conclusion Only 8 out of 213 cases in the present series experienced complications, which is significantly less than the complication rates observed in other reports. Consistent and conscientious protection of the dentition and of the oral mucosa and limiting suspension times to 30 minutes are factors unique to our series that appear to reduce complications in endolaryngeal surgery.

A case report of subglottic haemangioma

<p class="abstract">We report a case of 18 year old female who presented with hoarseness of voice and hemoptysis for 6 months eventually diagnosed as subglottic haemangioma through video laryngoscopy, CT imaging and histopathological examination of excision biopsy. The tumor excision was done by endolaryngeal surgery with tracheostomy under general anesthesia. The diagnosis of subglottic haemangioma, its management and prognosis were discussed.</p><p class="abstract"> </p>
