his presentation explores the validity and clinical usefulness of Supraomohyoid Neck Dissection (SOHND) in patients diagnosed with oral squamous cell carcinoma (OSCC) who present with a clinically negative neck (N0). The work is grounded in the understanding that cervical lymph node metastasis is the single most important prognostic factor in OSCC, capable of reducing survival by nearly half. Despite advances in imaging—including CT, MRI, PET/CT, and ultrasound-guided FNAB—no non‑invasive modality reliably detects occult metastasis. As a result, elective neck treatment remains a central consideration in managing N0 OSCC. The presentation begins by outlining the biological basis of cervical metastasis, describing the cascade of tumor invasion, angiogenesis, intravasation, and lymphatic spread. It highlights the high incidence of occult nodal disease reported in the literature, ranging from 20% to 45%, reinforcing the rationale for proactive surgical management even when the neck appears clinically uninvolved. The concept of selective neck dissection is introduced as a method that targets lymphatic levels at highest risk while preserving key anatomical structures such as the sternocleidomastoid muscle, internal jugular vein, and spinal accessory nerve. Among selective procedures, SOHND—removing lymph nodes from levels I, II, and III—has gained prominence due to its balance of oncologic safety and reduced morbidity. The study presented includes 61 consecutive patients treated between 2009 and 2010 at Abbasi Shaheed Hospital and the National Institute of Oral Diseases. All patients had biopsy‑proven OSCC with clinically N0 necks and underwent SOHND. Frozen section analysis guided intraoperative decisions, with conversion to MRND when metastasis was detected. Postoperative radiotherapy was administered based on tumor stage, margin status, and nodal positivity. The results demonstrate that SOHND yields an average of 20 lymph nodes per side, providing robust pathological staging. Occult metastasis was found in 34% of patients—an incidence high enough to justify elective neck dissection. Tumor depth emerged as a strong predictor: only 3% of tumors <5 mm deep showed nodal involvement, compared to 31% of those ≥5 mm. Recurrence was rare, occurring in only three patients; two contralateral recurrences were successfully salvaged, while one ipsilateral recurrence within the SOHND field proved fatal. The discussion emphasizes that SOHND is not only a staging tool but also demonstrates therapeutic value, achieving a regional control rate of 98% in pathologically node‑negative patients. In cases with occult metastasis, the addition of postoperative radiotherapy significantly improved neck control, underscoring its importance in high‑risk disease. The findings align with global literature suggesting that occult metastasis in OSCC typically involves levels I–III—precisely the levels addressed by SOHND. The presentation concludes that SOHND is both diagnostically sound and therapeutically effective for managing clinically N0 OSCC. It provides adequate lymphatic clearance, reliable staging information, and excellent regional control with minimal morbidity. For patients with occult nodal disease, adjuvant radiotherapy further enhances outcomes and is strongly recommended to prevent recurrences that may be difficult to salvage.
