Objective: Several laryngeal injection techniques are technically difficult and have limitations. In this study, we modified a transcricothyroid approach for injections to enhance needle visualization during procedures. The objective of this study was to investigate the efficacy of this alternative injection technique.
Methods: We performed a retrospective analysis of 51 patients who had undergone injection laryngoplasty for unilateral vocal paralysis between March 2014 and February 2015. In total, 17 patients underwent a transcricothyroid injection laryngoplasty via the contralateral paramedian approach (ILC) and 34 patients underwent transcricothyroid injection laryngoplasty via the conventional approach (ipsilateral approach, ILI). Acoustic analyses, aerodynamic analyses, voice handicap index (VHI), and GRBAS scale were assessed pre-operatively and at 2 weeks and 3 months postoperatively.
Results: From our acoustic and aerodynamic analyses, jitter, shimmer, noise-to-harmonic ratio (NHR), maximum phonation time (MPT), and mean flow rate (MFR) were all significantly improved in both groups after injection. VHI and GRBAS scales also improved postoperation. There were no significant differences between the pre-operative and postoperative subjective and objective parameters between both groups. The total injection volume used on the ILI group was larger than the volume given to the ILC group.
Conclusion: The transcricothyroid injection laryngoplasty via the contralateral paramedian approach is potentially more beneficial to performing injection laryngoplasty under local anesthesia. One important advantage of this approach to conventional approaches is its enhanced visualization of the needle during procedures.

Comparison of Complications of Injection Laryngoplasty via Direct Versus Flexible Laryngoscopy.

Department of Otolaryngology - Head and Neck Surgery, Thomas Jefferson University Hospital, Philadelphia, PA.
Objectives: Injection laryngoplasty (IL) is commonly performed for glottic insufficiency and has historically been performed under general anesthesia via direct laryngoscopy (DL), with an increasing number of procedures being performed in the office setting via flexible laryngoscopy (FL). Existing literature regarding complications of IL primarily addresses immediate peri-procedural complications and adverse reactions to the injection material. This is the first study utilizing a large multi-institutional database comparing complications of IL performed via DL versus FL.

Objectives: To investigate the relationship between social determinants of health and timeliness of management, adherence to follow-up, and outcomes of treatment with interarytenoid injection augmentation (IAIA).
Methods: Retrospective cohort study of all pediatric patients treated with IAIA at a large pediatric institution's multidisciplinary aerodigestive clinic between August 2022 and February 2024. Retrieved demographic factors, dates of referral, consultation, treatment, and follow-up, as well as objective measures of dysphagia and aspiration via videofluoroscopic swallow study (VFSS) reports, using dysphagia outcome and severity scale (DOSS) scores and the greatest unsafe thickness, or 'aspiration score'.

Background: Unilateral vocal fold paralysis (UVFP) is a common condition that may have varying economical and personal consequences for those afflicted by it. Patients often have dysphonia as a primary concern and may also experience aspiration in certain cases. This research aimed to assess the voice and swallowing results after injection laryngoplasty and medialization thyroplasty in patients with UVFP.

Objectives/hypothesis: Vocal impairments are early and debilitating symptoms of Parkinson's disease (PD). Glottal insufficiency is a contributor to PD-related dysphonia. Vocal fold injection laryngoplasty (IL) and medialization thyroplasty (MT) are well-established techniques used to restore glottal closure for a range of causes.
