As the benefits, limitations, and contraindications of transoral laser microsurgery (TLM) in glottic carcinoma treatments become better defined, pretreatment imaging has become more important to assess the case-specific suitability of TLM and to predict functional outcomes both for treatment consideration and patient counseling. Magnetic resonance imaging (MRI) is the preferred modality to image such laryngeal tumors, even though imaging the larynx using MRI can be difficult. The first challenge is that there are no commercial radiofrequency (RF) coils that are specifically designed for imaging the larynx, and performance in terms of coverage and signal-to-noise ratio is compromised using general-purpose RF coils...

PURPOSE: With adequate indication and meticulous execution, endoscopic procedures can efficiently treat a subset of adult and pediatric benign laryngotracheal stenosis and obstructions, but these procedures are precise and very demanding. The difference between a successful and a failed surgery, with potentially debilitating side effects, resides in small details. The learning curve is long and very few centers worldwide have a sufficient case load making adequate training difficult. While indications and concepts of endoscopic procedures can be learned in books and by observing trained colleagues, the dexterity and the precise realization need to be practiced, ideally not initially on patients...

OBJECTIVE: After that the establishment of transoral robotic surgery (TORS) for head and neck cancer has been adopted in North America, it has also recently been adopted in Europe. In these parts, transoral laser microsurgery (TLM) is widely applied. The aim of the study was to identify the absolute number of operations amenable to TORS at a TORS initiating institution on the basis of all former TLM cases. PATIENTS AND METHODS: All laser surgery procedures from May 2004 to April 2013 (108 months) were initially retrospectively registered; after that, all stage pT1 and pT2 squamous cell carcinomas of the oropharynx, hypopharynx, and larynx were selected...

Introduction: Carbon dioxide laser coagulation during transoral laser microsurgery (TLM) for laryngeal cancer allows control of bleeding from vessels smaller than 0.5 mm. Therefore, larger arteries and veins must be carefully managed by clipping and/or monopolar cautery. The aim of this paper is to detail endolaryngeal vascular anatomy and identify areas of possible bleeding during TLM. Methods: We performed an anatomical study on a series of 11 fresh-frozen human cadavers...

Snoring is a sleep phenomenon due to the partial upper airway obstruction during sleep which causes vibration of the tissues of the rhino-oro-hypopharynx and less frequently the larynx. This study evaluated the use and effectiveness of the erbium:YAG 2940-nm laser as an adjunctive in providing treatment for patients suffering from chronic snoring-related sleep disorders. A prospective study of 40 consecutive patients with snoring and sleep disorders was performed, assessing data before and after three Er:YAG laser treatment sessions...

A 12-year-old female presented with a 2-month history of dyspnea and a progressively worsening hoarseness lasting >10 years. The subsequently identified mass was completely resected from the patient's supraglottic area using a laser and suspension laryngoscope. The mass was diagnosed as a bronchogenic cyst using histopathology. While the prognosis for these cysts is good, long-term follow-up remains necessary for such patients because there are several reports in the literature indicating the potential for malignancy to develop...

INTRODUCTION: The vagus nerve has sensory and motor function in the larynx, as well as parasympathetic function in the thorax and abdomen. Stimulation of the superior laryngeal nerve can cause reflexive bradycardia. CASE: We describe a case of a 45-year-old man with pre-syncopal symptoms while exercising, and bradycardia found during cardiology workup. Radiography and flexible laryngoscopy showed evidence of a right-sided, vascular laryngeal mass. Exercise testing before and after superior laryngeal nerve block showed reversal of the symptoms with the block...

INTRODUCTION: Radical laryngeal surgeries for extensive laryngeal and hypopharyngeal tumors often require a permanent tracheostomy, which has an immense impact on the quality of life of patients. A minimally invasive technique such as transoral laser microresection (TLM) followed by radiotherapy can preserve the functions of the voice and swallowing. The aim of this study is to evaluate the role of laser debulking in the treatment of carcinoma of the larynx and hypopharynx, to evaluate the response of the tumor to subsequent radiotherapy, and also to assess the usefulness of laser in avoiding tracheostomy and functional preservation of the voice and swallowing...

Dear Editor, An 83-year-old woman developed yellow-brownish infiltrates, nodules, and tumors mimicking xanthomas, mostly involving the periorbital and chest area within three months (Figure 1). She had no abnormalities in serum cholesterol or triglycerides levels. A detailed laboratory analysis revealed the presence of mild monoclonal gammopathy with a presence of immunoglobulin G (IgG) kappa light chains; however, according to hematologist consultation, it did not require medical intervention. Imaging assessment and ultrasound examination did not show any specific involvement of internal organs...

Acronyms and abbreviations are frequently used in otorhinolaryngology and other medical specialties. CO2 laser-assisted transoral surgery of the pharynx, the larynx and the upper airway is a family of commonly performed surgical procedures termed transoral laser microsurgery (TLM). The abbreviation TLM can be confusing because of alternative modes of delivery. Classification and definition of the different types of procedures, performed transorally or transnasally, are proposed by the Working Committee for Nomenclature of the European Laryngological Society, emphasizing the type of laser used and the way this laser is transmitted...

INTRODUCTION: Glottic leakage during phonation is a direct consequence of unilateral vocal fold (VF) paralysis. This air leakage can be in the horizontal plane and in the vertical plane. Presently, there is no easily applicable medical device allowing noninvasive, office-based measurement of the relative vertical position of the VFs. The larynx ruler (LR) is a laser-based measuring device that could meet the previously stated need, using a flexible endoscope. This study represents a proof of concept regarding the use of the LR in assessing VF relative positions in the vertical plane...
