Medialization Laryngoplasty After Endoscopic Laser Cordectomy. Our Experience

Systematic Review and Meta-Analysis of Outcomes in Type 1 Thyroplasty Comparing Silastic to Gore-Tex

OBJECTIVE

Type 1 Thyroplasty is a well-established procedure used for medializing an immobile vocal fold. Silastic and Gore-Tex are the two most common materials used to accomplish this, but comparative data on their relative efficacy are scarce. We sought to compare outcomes between Silastic and Gore-Tex implants via systematic review and meta-analysis for unilateral vocal fold immobility.

METHODS

We collected available data from PubMed, Embase, and Web of Science on demographics, maximum phonation time (MPT), voice handicap index (VHI-10/30) score, and any other relevant metrics encountered before comparatively evaluating differences in outcomes.

RESULTS

The search yielded 1,534 records with 55 manuscripts ultimately included. There were 41 unique studies that utilized Silastic for a total of 1038 patients. There were 13 unique studies that utilized Gore-Tex for a total of 245 patients. The pooled mean increase in MPT for Silastic patients was 7.8 s (+1.3 SMD) compared with 5.7 s for Gore-Tex (+1.6 SMD). There was significant publication bias present in both analyses. The pooled mean change in VHI-30 with Silastic was -45.4 (62.2%, -2.09 SMD) compared with -51.6 (73.5%, -1.1 SMD) with Gore-Tex. The pooled mean change in VHI-10 with Silastic was -15.6 (54%, -0.46 SMD) compared with -11.6 (43%, -0.86 SMD) with Gore-Tex. There was no significant publication bias present in VHI outcomes.

CONCLUSIONS

Silicone and Gore-Tex implants provide adequate and comparable results in TT1. The data supporting this conclusion are limited by follow-up, diversity in outcomes, limited data availability, and publication bias. Future research should be dedicated to comparing implants in a well-randomized environment. Laryngoscope, 135:1236-1247, 2025.

Phonosurgical Injection Approaches for Voice Restoration After Open Partial Horizontal Laryngectomies: A Pilot Study

OBJECTIVE

The aim of the present study is to evaluate the efficacy of phonosurgical corrective approaches based on injection laryngoplasties and pharyngoplasties followed by speech therapy for voice restoration after unsatisfactory phonatory results of open partial horizontal laryngectomies.

METHODS

Ten patients with not satisfying phonatory results despite speech therapy after type II or type III open partial horizontal laryngectomies (OPHLs) were included. Each patient underwent a voice restoration program based on phonosurgery (injection laryngoplasty and/or injection pharyngoplasty) with hyaluronic acid and/or calcium hydroxyapatite, followed by post-surgical voice rehabilitation. Voices were recorded and analysed through spectrographic, aerodynamic, perceptual, laryngoscopic and self-assessment evaluations before the treatment (T0), after 1 month (T1) and after three months (T2).

RESULTS

Significant improvements in the patients voices were found between T0, T1 and T2 concerning acoustic, perceptual, aerodynamic, laryngoscopic and self assessment evaluations.

CONCLUSIONS

The results of the present study support phonosurgical injection procedures followed by speech therapy as an effective strategy for voice restoration after type II or type III OPHLs in selected patients.
