Comparison of New Telescopic Video Microlaryngoscopic and Standard Microlaryngoscopic Techniques

Abstract

A new approach to microlaryngeal surgery using a specially designed video microlaryngoscope with a rigid endoscopic telescope and an attached video camera was introduced by Kantor et al in 1990. The ability to video document and perform surgery of the larynx by viewing a high-resolution television image was demonstrated. This method was recommended over the standard microscopic technique for increased visibility with greater depth of field, unimpeded instrument access, instant documentation, and superior teaching value. The authors tried this new method and the standard microscopic technique at the same sitting on a series of patients. This paper will compare these two different techniques and discuss their advantages and disadvantages. Although the new method has many advantages, the standard microscopic technique remains as a valuable method in laryngeal surgery.

Role of the 30° Telescope in Evaluation of Laryngeal Masses During Direct Laryngoscopy

“…They have shown that the technique is not sufficient for evaluation of the ventricle, subglottic area, and anterior commissure. 17 Poels et al have compared the consistency of the preoperative and intraoperative diagnosis of 221 patients with benign vocal fold lesions. They used both halogen and stroboscopic light for the preoperative diagnosis and direct microscopic visualization for intraoperative diagnosis.…”

Desenvolvimento de protótipo para aplicação do laser de CO2 na laringe humana a curtas distâncias

“…Utilizando o segundo tipo de laringoscópio não obtiveram sucesso em 4,2% (1/24) dos pacientes, sendo o exame considerado difícil em outro paciente 20 . Na descrição do seu aparelho, Dedo alertou para as dificuldades da laringoscopia direta, relatando em seu trabalho a impossibilidade em 2,3% (2/85) dos pacientes.…”

Clinical Evaluation of 70° and 90° Laryngeal Telescopes

“…The frames obtained have sufficient lighting and excellent clarity, as is consistent with the findings of others. 6,12 Our definition of a "successful visualization" took into account both the ability to obtain a recording of the full region of interest and the tolerance of patients to the procedure. If patient discomfort was too great, the telescopy would be immediately discontinued at the patient's request and the examination considered unsuccessful.…”
