Ultrasound-Guided Hook-Wire Localization for Excision of Non-palpable Cervical Lesions Suspicious for Metastasis

The goal of this randomized controlled trial is to determine whether ultrasound-guided hook-wire localization improves surgical efficiency and accuracy compared with ultrasound-guided surgery alone for the excision of non-palpable or difficult-to-palpate cervical lesions suspicious for metastatic disease in adult patients. The main questions it aims to answer are: * Does ultrasound-guided hook-wire localization reduce operative time compared with ultrasound-guided excision alone? * Does hook-wire localization improve surgical precision, including successful retrieval of the target lesion for histopathological assessment? * Does hook-wire localization affect incision length, procedural difficulty, or the risk of surgical complications? Researchers will compare patients undergoing ultrasound-guided hook-wire localization followed by surgical excision with patients undergoing ultrasound-guided excision alone to determine whether hook-wire guidance improves surgical outcomes. Participants will: * Undergo ultrasound-guided localization and surgical excision of a cervical lesion or lymph node suspicious for malignancy. * Be randomly assigned to either: ultrasound-guided hook-wire localization before surgery, or ultrasound-guided excision without hook-wire localization. * Have surgical outcomes assessed, including operative time, incision length, successful lesion retrieval, procedural difficulty, and intraoperative or postoperative complications.
