The treatment outcome of advanced squamous cell carcinoma involving the head and neck is well known to be dire and usually needs multimodality treatment even including optimal reconstruction after ablative surgery. When a significant area of the soft tissue is resected, reconstruction of oral cavity or pharynx needs to minimize morbidities while achieving adequate functional outcomes. For the better functional outcome, invasive approaching procedures such as lip and jaw splitting, or extensive floor of mouth or pharyngeal muscle ablation should be avoided. Without these surgical procedures, reconstructive surgeons may encounter technical difficulties in flap inset due to deep and narrow space after head and neck cancer resection. In a deep and narrow surgical defect, accurate approximation and suture is extremely difficult. Eventually, repeated flap manipulation and stretch might be inevitable, and even pedicle kinking or injury could happen. Herein, we suggested the “parachute” technique, which was generally used in blood vessels or aortic valve suturing in a narrow surgical field and for avoiding mismatched suture. We applied this “parachute” technique for free-flap inset to head and neck defect, and we herein report our successful outcomes.
2.Surgical Intervention for Presbyphonia
Journal of the Korean Society of Laryngology Phoniatrics and Logopedics 2024;35(2):46-49
Current therapeutic approaches for presbyphonia are generally categorized into non-invasive and surgical methods. Voice therapy is commonly chosen as initial treatment modality used to reduce maladaptive compensatory muscle behavior and to improve glottal closure. Nevertheless, in advanced cases of presbyphonia, glottal insufficiency may be aggravated, reducing the benefits of voice therapy. To manage the glottal insufficiency observed in such cases, surgical intervention is performed to medialize the vocal folds. Available surgical modalities include injection laryngoplasty and type I thyroplasty. Additionally, cutting-edge regenerative treatments, such as the injection of basic fibroblast growth factor, are under investigation internationally and show promising outcomes. This review aims to elucidate the current indications and relevance of surgical interventions for presbylarynx.

Diffuse large B cell lymphoma (DLBCL), being one of the major subtypes of non-Hodgikin’s lymphoma, is marked by extranodal involvement. In patients with DLBCL, the stomach and gastrointestinal tract are commonly involved, but few cases have reported the involvement with the middle ear cavity and temporal bone. The present study reports a patient diagnosed with DLBCL characterized by middle ear cavity involvement. We also reviewed other similar cases in the literature.

New supplements with preventive effects against skin photodamage are receiving increasing attention. This study evaluated the anti-photoaging effects of salmon nasal cartilage proteoglycan (SPG), acting as a functional material for skin health. We administered SPG to in vitro and in vivo models exposed to ultraviolet B (UVB) radiation and assessed its moisturizing and anti-wrinkle effects on dorsal mouse skin and keratinocytes and dermal fibroblasts cell lines. These results showed that SPG restored the levels of filaggrin, involucrin, and AQP3 in the epidermis of UVB-irradiated dorsal skin and keratinocytes, thereby enhancing the keratinization process and water flow. Additionally, SPG treatment increased the levels of hyaluronan and skin ceramide, the major components of intercellular lipids in the epidermis. Furthermore, SPG treatment significantly increased the levels of collagen and procollagen type 1 by down-regulating matrix metalloproteinase 1, which play a crucial role in skin fibroblasts, in both in vitro and in vivo models. In addition, SPG strongly inhibited mitogen-activated protein kinase (MAPKs) signaling, the including extracellular signal-regulated kinase, c-Jun N-terminal kinase (JNK), and p38. These findings suggest that dietary SPG may be an attractive functional food for preventing UVB-induced photoaging. And this SPG product may provide its best benefit when treating several signs of skin photoaging.
