Abstract

Objective: The study aimed to evaluate the effectiveness of using a modified supraclavicular flap in reconstructing hypopharyngeal defects after hypopharyngeal resection surgery to treat stage III-IV hypopharyngeal cancer. Patients & methods: Prospective study, clinical intervention without control group. Performed on 30 patients with stage III-IV hypopharyngeal cancer, with squamous cell carcinoma histology, who underwent total laryngectomy with partial or complete hypopharyngectomy and immediate reconstruction with supraclavicular fascia skin flap at the head and neck - ENT department of Ho Chi Minh City Oncology Hospital from January 2021 to September 2023. Results: The disease is in stages III and IV A with 4 cases of T3 and 26 cases of T4. 24 cases had initial surgery, 6 cases had prior chemotherapy or radiotherapy. 5 cases had the entire hypopharynx removed, 25 cases had part of the hypopharynx removed. Neck lymph node dissection 26 cases. Flap size ranges from an average of 20.6 * 7cm. All flaps healed well and did not require re-operation, there was only 1 case of partial flap necrosis and self-stabilization. There were 3 cases of throat fistula, 7 cases of fluid collection, infection and 3 cases requiring feeding through nasogastric tube. The average swallowing quality assessment is 93 points. Conclusion: Extended supraclavicular pedicled flap is a suitable choice for hypopharyngeal-esophageal reconstruction.
