Post-surgical and oncologic outcomes of frontal anterior laryngectomy with epiglottic reconstruction: a review of 68 cases

Closure without epiglottoplasty or tracheotomy after reconstructive frontal anterior laryngectomy

Reconstructive frontal anterior laryngectomy (RFAL) is a partial laryngeal surgery technique for resecting early-stage (T1-T2) glottic squamous cell carcinoma. Indications comprise a lesion of the anterior commissure of the larynx that cannot be adequately exposed by endoscopy, and cases in which radiotherapy is refused or contraindicated. The initial RFAL technique included epiglottoplasty. Here we propose a technique without epiglottoplasty, with the advantage of avoiding need for tracheotomy in most cases. After the first stage of surgical excision, reconstruction consists in placing a vertical brace transepiglottically and below the cricoid. The epiglottis is thus left at its original height and secured in place to prevent flapping in the pharyngolaryngeal lumen. Transverse bracing is then performed through the thyroid wings: one of the key points of this surgery is to control tension to avoid risk of stenosis. The subhyoid muscles are sutured together to achieve satisfactory sealing. This technique offers satisfying functional results and oncological control. The most frequent complications are (1) secondary tracheotomy, which can be avoided by selecting patients who require a primary tracheotomy and optimizing the seal, and (2) stenosis, which can be limited by not bringing the cartilaginous structures too close together during bracing.

Laryngeal function-preserving of frontolateral vertical partial laryngectomy (FLVPL) for selected T4a glottic cancer with thyroid cartilage invasion adherence to the anterior commissure: an innovative attempt

OBJECTIVE

To evaluate the feasibility and efficacy in selected T4a glottic cancer (thyroid cartilage invasion adherence to the anterior commissure) treated with frontolateral vertical partial laryngectomy (FLVPL) and laryngeal framework reconstruction using titanium mesh.

METHODS

Six patients with the limited T4a glottic cancer with thyroid cartilage destruction adherence to the anterior commissure, underwent FLVPL from 2009 to 2016 in Sun Yat-Sen University Cancer Center. All patients were followed up postoperatively.

RESULTS

All patients comprised radical tumor resection and favorable functional outcomes, and no aspiration and laryngeal stenosis were observed. According to postoperative pathology, four patients should go through postsurgical radiotherapy with a mean dose of 66 Gy. But one of them refused to undergo postoperative radiotherapy, who observed local recurrence in postcricoid area underwent total laryngectomy (TL) and ipsilateral selected neck dissection in post-surgery two year. During follow-up period, all patients were still alive, and five patients without local recurrence and distant metastases.

CONCLUSION

FLVPL and laryngeal framework reconstruction using titanium mesh is one viable surgical procedure to obtain adequate oncologic and functional outcomes.
