Parapharyngeal space tumor surgery using a modified cervical-parotid approach

Area of Science:

• Otolaryngology
• Neurosurgery
• Surgical Oncology

Background:

• The cervical approach to parapharyngeal space tumors can be blind when operating near the skull base.
• Tumor resection in this region poses risks to vital structures, including the facial nerve.

Observation:

• A novel surgical technique involves identifying the temporal branch of the facial nerve and approaching the skull base through the parotid gland.
• This allows for clear visualization of the superior tumor extent before proceeding with dissection.

Findings:

• The combined cervical-parotid approach was successfully used in eight patients.
• All patients experienced favorable post-operative outcomes without any instances of facial paralysis.

Implications:

• This modified approach enhances surgical safety and efficacy for parapharyngeal space tumors.
• It facilitates precise tumor separation near the skull base while preserving facial nerve function.
