Transoral Robotic Surgery (TORS) - Procedures, Preparation, Cost, and Recovery

Transoral Robotic Surgery (TORS) is a minimally invasive surgical technique that utilizes robotic systems to perform surgeries through the mouth. This innovative approach allows surgeons to access hard-to-reach areas in the throat, mouth, and neck with enhanced precision and control. The primary purpose of TORS is to treat various conditions affecting the oropharynx, which includes the base of the tongue, tonsils, and soft palate.

The TORS procedure employs advanced robotic technology which provides surgeons with a three-dimensional view of the surgical site and allows for greater dexterity than traditional surgical methods. This is particularly beneficial in delicate areas where traditional open surgery may pose higher risks or result in more significant complications.

TORS is primarily used to treat conditions such as:

• Oropharyngeal Cancer: This includes cancers of the tonsils, base of the tongue, and other areas within the oropharynx. TORS can effectively remove tumors while preserving surrounding healthy tissue.
• Benign Tumors: Non-cancerous growths in the throat or mouth can also be addressed using TORS, allowing for their removal with minimal impact on the patient’s function and appearance.
• Sleep Apnea: In some cases, TORS can be used to remove obstructive tissue in the throat, helping to alleviate symptoms of obstructive sleep apnea.
• Recurrent Tonsillitis: For patients who suffer from chronic tonsillitis, TORS can facilitate the removal of the tonsils with less postoperative pain and quicker recovery.

The TORS procedure is performed under general anesthesia, and the robotic system is controlled by a skilled surgeon who operates from a console. The robotic arms are equipped with specialised instruments that enable precise movements, helping the surgeon navigate the complex anatomy of the throat and mouth.

Why is Transoral Robotic Surgery (TORS) Done?

Transoral Robotic Surgery (TORS) is typically recommended for patients who present specific symptoms or conditions that warrant surgical intervention. The decision to proceed with TORS is often based on a combination of clinical findings, imaging studies, and the overall health of the patient.

Common symptoms that may lead to the recommendation of TORS include:

• Persistent Sore Throat: A sore throat that does not improve with standard treatments may indicate an underlying issue, such as a tumor or chronic infection.
• Difficulty Swallowing (Dysphagia): Patients experiencing pain or difficulty when swallowing may have obstructive lesions in the throat that can be addressed through TORS.
• Unexplained Weight Loss: Significant weight loss without a clear cause can be a red flag for malignancy, prompting further investigation and potential surgical intervention.
• Lumps or Masses in the Neck: The presence of swollen lymph nodes or masses in the neck can suggest cancer, necessitating a biopsy or removal of the affected tissue.
• Changes in Voice: Hoarseness or other voice changes that persist may indicate a problem in the larynx or surrounding structures, which TORS can help evaluate and treat.

TORS is typically recommended when other treatment options, such as radiation or chemotherapy, are not suitable or when a more direct surgical approach is necessary. The procedure is particularly advantageous for patients with early-stage cancers, especially for head and neck cancers, as it allows for effective tumor removal while preserving surrounding healthy tissue and minimising the impact on speech and swallowing functions. Moreover, you should know that not all cancerous tumours are suitable for TORS; their suitability depends on tumour size, location, and staging.

Indications for Transoral Robotic Surgery (TORS)

The indications for Transoral Robotic Surgery (TORS) are based on specific clinical situations, diagnostic findings, and the overall health status of the patient. Candidates for TORS typically present certain characteristics that make them suitable for this innovative surgical approach.

• Diagnosis of Oropharyngeal Cancer: Patients diagnosed with early-stage oropharyngeal cancer, particularly those associated with human papillomavirus (HPV), are often ideal candidates for TORS. The procedure allows for the removal of tumors while preserving critical structures, which is essential for maintaining function.
• Benign Lesions: Individuals with benign tumours or lesions in the oropharynx that cause symptoms such as dysphagia or obstructive sleep apnea may be considered for TORS in specific cases involving hypertrophied tissues like the tongue base or palate. But it’s not a universal treatment for sleep apnea. This minimally invasive nature of the procedure reduces recovery time and postoperative discomfort.
• Recurrent Tonsillitis: Patients suffering from recurrent tonsillitis who have not responded to conservative treatments may benefit from TORS for tonsillectomy. This approach can lead to less pain and quicker recovery compared to traditional tonsillectomy methods.
• Lymphadenopathy: Patients with unexplained lymphadenopathy (swollen lymph nodes) in the neck may undergo TORS for biopsy or removal of affected lymph nodes to determine the underlying cause, especially if malignancy is suspected.
• Functional Impairments: Those experiencing significant functional impairments related to swallowing or breathing due to obstructive lesions may be candidates for TORS. The procedure can alleviate symptoms and improve quality of life.
• Patient Health Status: TORS is often recommended for patients who are otherwise healthy and can tolerate general anesthesia. The minimally invasive nature of the procedure is particularly beneficial for older patients or those with comorbidities who may not be suitable for more extensive surgeries.

Thus, Transoral Robotic Surgery (TORS) is a cutting-edge surgical technique that offers numerous benefits for patients with specific conditions affecting the oropharynx. By understanding the indications for TORS, patients and healthcare providers can make informed decisions about the best treatment options available. While TORS is suitable for many patients, certain factors may contraindicate its use.

Contraindications for Transoral Robotic Surgery (TORS)

Transoral Robotic Surgery (TORS) is a minimally invasive surgical technique that offers numerous benefits for patients with head and neck conditions, particularly those involving the oropharynx. However, not every patient is a suitable candidate for this innovative procedure. Understanding the contraindications is crucial for both patients and healthcare providers to ensure safety and optimal outcomes.

• Anatomical Considerations: Patients with significant anatomical abnormalities in the head and neck region may not be suitable for TORS. This includes individuals with severe jaw restrictions, such as those with temporomandibular joint disorders or significant trismus (limited mouth opening). These conditions can hinder the surgeon's ability to access the surgical site effectively.
• Tumor Size and Location: TORS is typically indicated for smaller tumors located in the oropharynx. Patients with large tumors or those that have invaded surrounding structures, such as the base of the skull or major blood vessels, may require more extensive surgical approaches. Additionally, tumors that are not amenable to transoral access may be contraindicated.
• Medical Comorbidities: Certain medical conditions can increase the risks associated with TORS. Patients with severe cardiovascular or pulmonary diseases may not tolerate the anesthesia or the positioning required during the procedure. Additionally, individuals with uncontrolled diabetes or other systemic diseases may face higher risks of complications.
• Prior Radiation Therapy: Patients who have undergone radiation therapy to the head and neck region may have altered tissue characteristics, making TORS more challenging. Radiation can lead to fibrosis and scarring, which may complicate the surgical approach and healing process.
• Infection or Active Disease: Active infections in the oral cavity or throat can pose significant risks during TORS. Surgeons typically avoid performing the procedure in the presence of active infections to prevent complications and ensure a sterile environment.
• Patient Preference: Some patients may not be comfortable with the idea of robotic surgery or may prefer traditional surgical methods. It is essential for patients to discuss their concerns and preferences with their healthcare team to determine the best approach for their individual situation.

How to Prepare for Transoral Robotic Surgery (TORS)?
