“…Hiramatsu et al [14] reported that the 3D-CT images obtained while the glottis was closed (with phonation) and open could provide information about the reasons for unsatisfactory outcomes of laryngoplasty. In addition, Hara et al [15] demonstrated that preoperative determination of the window position in MT using digital imaging software-reconstructed 3D-CT images produced good vocal outcomes after MT. Indeed, in the present series of UVFP patients, laryngeal 3D-CT images could depict the position of the arytenoid cartilage, window, and implant, as well as the size of the implant and the degree of correction of the vocal fold, and the inter-rater reliabilities for all the factors were judged to be moderate or better.…”

Twelve patients with a poor outcome and 10 with a good outcome showed 36 and 18 abnormal findings identified by either of the two laryngologists, respectively. In the poor outcome group, a smaller implant size and undercorrection of the vocal fold showed both high kappa values and a significantly higher prevalence than those in the good outcome group (p < 0.001 and p < 0.05), respectively. The comparison between material types demonstrated that the sheet-like material (ePTFE) group exhibited a significantly higher prevalence of undercorrection than the block-like material group (p < 0.05).

“…Recently, 3D-CT has been utilized to estimate the vocal fold condition in UVFP patients [12][13][14][15]. Yumoto et al [13] reported that 3D-CT endoscopic images could depict sagging/thinning and adduction/augmentation of the affected vocal fold before and after phonosurgery, respectively.…”

“…Nevertheless, the configuration model provided pivotal information in raising awareness about the customized treatment of unilateral vocal palsy patients. Hara et al 26 published the outcomes of using 3D CT image to predict vocal cord plane and optimal implant size, which resulted in reducing the operation time by 12 minutes. Our proposed 3D printed models not only provided a direct visualization of glottal configuration in different patients irrespective of the etiology or the severity of vocal cord palsy but also gave crucial information on the arytenoid cartilage’s condition, which made patient-tailored medialization laryngoplasty surgery possible.…”

Background: The clinical outcomes of surgical treatments for vocal cord paralysis and tracheal stenosis, such as medialization laryngoplasty and laryngotracheal reconstruction, vary owing to the complex anatomy and physiology of the human upper airway. However, advances in three-dimensional (3D) simulation and printing ushered its use on an office-based workstation to aid in several surgical areas. Methods: The preoperation neck computed tomography image was loaded into the InVesalius 3.0 software for manual segmentation of airway and nearby important anatomic landmarks including hyoid bone, thyroid cartilage, and cricoid cartilage. The 3D model of the desired anatomy structure was manufactured and used for presurgical planning and rehearsal of the surgery. Results: We review cases of four patients: two cases of unilateral vocal palsy undergoing medialization laryngoplasty and two cases of tracheal stenosis patients who used the air-cartilage combined model Conclusion: Preoperation planning of the medialization thyroplasty could be more precise by prevision of the paralyzed vocal cord plane. Tracheal surgery could benefit from a preoperative design of segmented length. The novel airway-cartilage combined model offers new insight into vocal cord and trachea surgery.

Purpose The purpose of this study is to familiarize speech-language-pathologists with the current state of the science regarding medialization laryngoplasty in the treatment of voice disorders, with emphasis on current evidence-based practice, voice outcomes, and future directions for research. Method A literature review was performed in PubMed and Embase using the keywords vocal fold/cord and laryngoplasty, thyroplasty, augmentation, or laryngeal framework . Articles published between 2010 and 2020 were reviewed for data about clinical applications, technical approach, voice-related outcomes, and basic science or clinical innovations with the potential to improve patient care. A synthesis of data was performed from articles meeting the outlined search criteria. Conclusions As key members in the multidisciplinary care of voice disorders, speech-language pathologists need to be informed of current research in medialization laryngoplasty, a procedure commonly used for patients with glottic insufficiency. Advances in anesthetic technique, office-based procedures, and the development of materials with increased bio-tolerability over the past decade have led to innovations in treatment and improved patient outcomes. Recent applications of computational and bioengineering approaches have the potential to provide new directions in the refinement of currently available techniques and the improvement of patient-based treatment outcomes.
