Objective: To determine the differences in thermal effects on vocal folds between four fiber-routed lasers.
Methods: In this experimental laboratory study the thermal effects of an AcuPulse Duo CO (CO AP), UltraPulse Duo CO (CO UP), KTP, and Blue laser were analyzed using a Schlieren technique on a human tissue mimicking gel model. Power, laser duration, laser fiber distance to tissue and mode (continuous wave [CW] vs pulsed [P] modes) were evaluated in varying combinations in order to compare the effects of the tested lasers and to explore the individual effect on thermal expansion and incision depth of each setting.
Article Synopsis
- The study assessed the placement of the Slim Modiolar Electrode (SME) using the extended Round Window (eRW) method, focusing on its impact on hearing preservation and speech perception.
- Twenty-three adults were implanted with the SME; their electrode positioning was monitored both during and after surgery, with evaluations on hearing and speech conducted 2 and 12 months later.
- The results showed effective electrode insertion and significant improvement in speech perception, but only moderate residual hearing preservation, suggesting the eRW method may not be universally applicable for all patients.
Article Synopsis
- Cochlear implantation can lead to inflammation, fibrosis, and new bone formation (NBF), potentially affecting residual hearing.
- A study involving 123 participants analyzed NBF using ultra-high-spatial-resolution CT and found it present in 68% of cases, primarily around the basal electrode contacts.
- Significant associations were observed between NBF and both electrode type and surgical technique, indicating that different approaches may influence hearing outcomes post-implantation.
Objective: The aim of this study was to compare Transimpedance Matrix (TIM-) measurement and X-ray fluoroscopy for the intraoperative detection of electrode array tip fold-over in cochlear implant recipients.
Study Design: Retrospective agreement study.
Setting: Tertiary referral hospital.
Objectives: The aim of this study is to report on our preliminary experience with Transimpedance Matrix (TIM)-measurement for the detection of cochlear implant electrode tip foldovers compared with intraoperative imaging in patients implanted with the slim modiolar electrode (SME).
Study Design: Proof of concept study.
Setting: Tertiary university referral center.
Objectives/hypothesis: To provide insight in the thermal effects of individual laser settings in target tissues to optimize flexible endoscopic CO laser surgery treatment.
Study Design: Experimental laboratory study.
Methods: Thermal effects of the CO laser using a fiber delivery system were visualized using the color Schlieren technique in combination with a polyacrylamide gel tissue model.
