Larynx preservation treats laryngeal and hypopharyngeal cancer while keeping the voice box, so that patients may continue to speak, breathe, and swallow without a permanent tracheostomy.
The table below lists the main approaches and the situations in which each is typically used.
| Approach | How it works | Typically used for |
|---|---|---|
| Transoral laser microsurgery (TLM) | Laser removal through the mouth | Early glottic and supraglottic cancers |
| Transoral robotic surgery (TORS) | Robotic instruments through the mouth | Selected throat and supraglottic tumors |
| Partial (conservation) laryngectomy | Removes part of the larynx; keeps voice and airway | Selected intermediate-stage tumors |
| Concurrent chemoradiation | Radiation with chemotherapy, usually cisplatin | Stage III and IV without cartilage destruction |
| Radiation therapy alone | Precision radiation without surgery | Early laryngeal cancer |
Transoral robotic surgery is a minimally invasive procedure in which surgeons remove tumors of the oropharynx, tongue base, and tonsil through the mouth using a robotic system, avoiding external incisions and jaw-splitting operations.
TORS is especially relevant for HPV-related oropharyngeal cancer, where favorable survival outcomes make it important to reduce long-term swallowing problems. Potential benefits include less tissue disruption, shorter hospital stays, and, in some patients, lower radiation doses afterwards. It requires careful patient selection and an experienced team.
For appropriately selected patients, organ preservation with chemoradiation or conservation surgery has shown cancer control comparable to total laryngectomy while retaining the natural voice.
Landmark trials, including the VA Larynx study and RTOG 91-11, showed that concurrent chemoradiation preserved the larynx in most patients with advanced disease, with survival similar to laryngectomy. Total laryngectomy is still preferred when there is extensive cartilage invasion, tumor spread outside the larynx, or poor baseline swallowing or airway function, or when chemoradiation fails, in which case salvage laryngectomy is performed.
Many patients treated with organ-preserving approaches keep functional speech and swallowing, and early rehabilitation with a speech-language pathologist may improve the outcome.
The table below summarizes the supportive services that commonly accompany treatment.
| Service | Purpose | Typical timing |
|---|---|---|
| Swallowing pre-habilitation | Maintains muscle strength and swallowing function | Before or during radiation |
| Speech-language therapy | Voice and swallowing therapy | During and after treatment |
| Nutrition support | Dietitian guidance; temporary feeding tube if needed | Before and during treatment |
| Dental evaluation | Protects teeth and jawbone | Before radiation |
| Surveillance visits | Throat examination with periodic imaging | Every 1 to 3 months in the first two years |
