RESUMEN

BACKGROUND: Preserving laryngeal function and reconstructing the hypopharynx in advanced hypopharyngeal cancer pose significant challenges for head and neck surgeons. METHODS: A 48-year-old male patient was diagnosed with advanced hypopharyngeal cancer originating from the left pyriform sinus. The tumor extended into the hypopharynx, left vocal cord, ventricular fold, partial aryepiglottic fold, and a segment of the cervical esophagus. A curative tumor resection was performed, and a well-thought-out strategy was employed for hypopharyngeal repair and laryngeal reconstruction. RESULTS: Following the surgery, the patient demonstrated exceptional flap survival, and the tracheostomy tube was removed at the 6-month mark. No surgery-related complications were observed, and both swallowing and vocal functions exhibited a robust recovery. CONCLUSION: Our reconstruction strategy proves effective in preserving laryngeal function among patients with advanced hypopharyngeal cancer.

RESUMEN

Photodynamic therapy has emerged as a recognized anti-tumor treatment involving three fundamental elements: photosensitizers, light, and reactive oxygen species. Enhancing the effectiveness of photosensitizers remains the primary avenue for improving the biological therapeutic outcomes of PDT. Through three generations of development, HPPH is a 2-(1-hexyloxyethyl)-2-devinyl derivative of pyropheophorbide-α, representing a second-generation photosensitizer already undergoing clinical trials for various tumors. The evolution toward third-generation photosensitizers based on HPPH involves structural modifications for multimodal applications and the combination of multifunctional compounds, leading to improved imaging localization and superior anti-tumor effects. While research into third-generation HPPH is beneficial for advancing PDT treatment, equal attention should also be directed toward the other two essential elements and personalized diagnosis and treatment methodologies.

RESUMEN

OBJECTIVES: The Lateral Arm Free Flap (LAFF) offers advantageous features like variable thickness and minimal hair growth. LAFF is primarily used in orofacial and pharyngeal reconstructions, with limited reports on tracheal/esophageal applications. Also, the psychological prognosis and quality of life in patients with LAFF reconstruction are lacking. METHODS: This retrospective case series presents outcomes of LAFF reconstruction for head and neck surgical defects which included 19 patients. The disease type, location of reconstruction, TNM staging, tumor size, chemoradiation status, anxiety, depression, quality of life and detailed perioperative information of the LAFF reconstruction surgery were presented in a descriptive pattern. Subgroup analysis was conducted using Mann-Whitney U and Pearson r test. RESULTS: All 19 patients (100%) had a viable flap after surgery with 5 (26.3%) of them developed flap-related complication. Patients with oropharyngeal reconstruction were more likely to have lower anxiety and depression score and higher quality of life than those with below-oropharyngeal reconstruction. However, no significant p-value was generated in any subgroup comparison or correlation test. And the application of LAFF in esophageal and tracheal reconstruction was proved to be successful. CONCLUSIONS: The lateral arm free flap exhibits remarkable versatility and multifunctionality, providing advantageous outcomes in head and neck reconstruction. LEVEL OF EVIDENCE: Level 4 according to OCEBM.
