Endoscopic-Guided Suture Lateralization for Bilateral Vocal Fold Paralysis: Surgical Tips for Better Outcome

OBJECTIVE

This study aims to describe a precise description of suture lateralization (SL) technique and evaluate its effectiveness and safety in management of bilateral vocal fold paralysis (BVFP).

METHOD

A preclinical cadaveric study followed by application on a case series of BVFP patients. After the preliminary study executed to precisely localize the optimal sites for needle insertion, a prospective interventional study was conducted on 19 subjects presenting with respiratory distress due to BVFP. Data collection included their clinical presentation and a detailed assessment including auditory perceptual assessment, laryngoscopy (rigid or flexible), and video fluoroscopic swallowing study.

RESULTS

Widening of the inter-glottic distance at the site of the sutures was statistically significant (P < 0.001). Decannulation was achieved in three out of four tracheotomized patients. The suturing led to a significant difference in loudness, jitter, and harmonic-to-noise ratio (P = 0.042, 0.004, and ≤0.001, respectively).

CONCLUSION

This study suggests that SL is a feasible and effective technique with low incidence of adverse events and the potential of reversibility. Optimal localization of the suture insertion points translated into less intraoperative manipulation of the cords and shorter operative time.

Multimodality imaging of pediatric airways disease: indication and technique

Congenital and acquired airway anomalies represent a relatively common albeit diagnostic and therapeutic challenge, even for the most skilled operators in dedicated centers. Airway malformations encompass a wide spectrum of pathologies involving the larynx, trachea and bronchi, esophagus, mediastinal vessels. These developmental lesions are often isolated but the association of two or more anomalies is not infrequent. From the traditional chest X-ray to the newest applications of Optical Coherence Tomography, non- or mini-invasive diagnostic techniques represent useful tools to integrate invasive procedures. Comprehensive knowledge of the characteristics of each diagnostic test is mandatory for its useful application. The aim of our paper is to analyze the clinical indications for Imaging the Airway disease in pediatric population, and describe the diagnostic techniques. Only by a close interaction between all the operators involved in diagnosis and treatment of pediatric airway, as it happens in Multidisciplinary Airway Team, the non- or mini-invasive imaging is effective.
