Abstract

Objective:

To investigate the oncological and functional outcomes of the patients treated with transoral CO2 laser cordectomy for early glottic cancer.

Patients And Methods:

Fifty-five consecutive patients who underwent CO2 laser cordectomy for early glottic cancer were retrospectively reviewed.

Results:

Overall survival, larynx preservation, and relapse free local control rates were 96%, 100%, and 91%, respectively. Five patients with local recurrences were salvaged with re-cordectomy and/or radiotherapy. In type I cordectomy, VHI-10 consistently improved during postoperative course and VHI-10 at postoperative 12months was significantly better than preoperative value (2.3 vs. 9.4, p=0.02). Perceptual grading, MPT, MFR and AC/DC also improved and were better than preoperative values. In type III cordectomy, shimmer at 12months after cordectomy was significantly better than preoperative value (14.7 vs. 9.3, p=0.007).

Conclusions:

These results further support the rationale of CO2 cordectomy as initial and salvage surgery for early glottic cancer.

Keywords:

Focal Laser Ablation of Prostate Cancer: An Office Procedure

This article presents and describes an outpatient treatment for prostate cancer using focal laser ablation. Laser catheter placement is guided by MRI-ultrasound fusion imaging in a fashion similar to prostate needle biopsy. Treatment is monitored in real-time with a thermal probe, placed adjacent to the laser fiber.

Lateral Molar Approach-Driven Transoral Endoscopic Procedure for Benign Infratemporal Fossa Tumor Resection

Here, we present a protocol to resect benign infratemporal fossa tumors via an endoscopic-assisted transoral lateral molar approach with low-temperature plasma ablation and intraoperative mandibular nerve monitoring. This minimally invasive technique prioritizes anatomical preservation, functional recovery, and avoidance of external scarring, demonstrating feasibility for well-demarcated lesions ≤4 cm in...
