Summary
A rare complication of medialization laryngoplasty (ML) involves the thyroid cartilage window migrating into the larynx years after surgery. This case highlights the importance of removing the cartilage window during ML to prevent such late complications.
Area of Science:
- Otolaryngology
- Laryngeal Surgery
- Vocal Cord Surgery
Background:
- Medialization laryngoplasty (ML), or thyroplasty type 1, is a surgical procedure to improve voice quality.
- Complications of ML are typically discussed as early post-operative events.
Observation:
- A 64-year-old female presented with persistent dysphonia and a laryngeal mass five years after ML with a Silastic implant.
- Imaging revealed migration of the thyroid cartilage window into the laryngeal ventricle, distinct from the Silastic implant.
Findings:
- The thyroid cartilage window fragment migrated into the laryngeal ventricle, causing a late complication.
- Surgical exploration confirmed the migrated cartilage fragment and Silastic implant.
- The patient was successfully treated by removing the implant and cartilage fragment, followed by autologous lipoinjection.
Implications:
- Retention of the thyroid cartilage window during ML may lead to late-onset complications.
- This case suggests that complete removal of the cartilage window is crucial for long-term ML success.
- Further research into optimizing ML techniques to minimize late complications is warranted.
