To optimize treatment of zygomatic bone fractures, patients' subjective evaluations of symptoms are necessary. The visual analog scale (VAS) was used for the quantitative assessment of subjective evaluation for symptoms and treatments in patients who underwent open reduction and rigid fixation. Degree of satisfaction and annoyances resulting from residual(More)
Temporalis muscle transfer for paralytic lagophthalmos, which was first proposed by Gillies and later developed by Andersen, has been one of the most common treatment modalities for paralytic lagophthalmos. However, there have been no scientific reports statistically analysing the efficacy of temporalis muscle transfer. We, therefore, retrospectively(More)
BACKGROUND This study aimed to compare several microvascular anastomotic techniques by patency rate using a free flap model in rats. METHODS A microsurgical transfer model of a pectoral skin flap to the cervical region was used. In experiment 1, 120 rats were divided into four groups (n = 30 in each group) depending on the type of microvascular(More)
Osteoarthritis (OA) is a common disease in the elderly due to an imbalance in cartilage degradation and synthesis. Heterotopic ossification (HO) occurs when ectopic masses of endochondral bone form within the soft tissues around the joints and is triggered by inflammation of the soft tissues. Procyanidin B3 (B3) is a procyanidin dimer that is widely studied(More)
It was recently revealed that epidermal growth following topical treatment with all-trans retinoic acid (atRA) was at least partly induced by heparin-binding epidermal growth factor-like growth factor (HB-EGF) released from suprabasal keratinocytes. Since proliferation of keratinocytes appears to be one of the critical roles of atRA in depigmentation(More)
Neurovascular free muscle transfer is now the mainstay for smile reconstruction in the treatment of established facial paralysis. Since facial paralysis due to ablative surgery or some specific disease sometimes accompanies defects of the facial skin and soft tissue, simultaneous reconstruction of defective tissues with facial reanimation is required. The(More)
We did a simultaneous reconstruction of the upper lip and the supportive columella for a midface deformity caused by the wide resection of a squamous cell carcinoma of the nasal vestibule. It was reconstructed with an Abbe flap combined with a periosteally-vascularised outer layer of mandibular bone, which give an aesthetically and functionally acceptable(More)
Salvage reconstruction of the oesophagus is still considered a challenging procedure for all head and neck surgeons. The risk of postoperative infection and delayed wound healing is high because of thick scar formation and persistent inflammation. Furthermore, recipient vessels for free tissue transfer or vascular supercharge are not always available.(More)
We seldom have difficulties in the selection of appropriate recipient arteries for microvascular free flap transfer in the head and neck region because many sizable branches (branch artery) of the external carotid artery (ECA) or subclavian artery are available. However, we occasionally encountered the lack of an appropriate recipient artery, especially in(More)
We report the cases of two patients who had pronounced stenosis of the lower part of the vagina after vaginal reconstruction for congenital vaginal aplasia and hypoplasia. Bilateral pudendal thigh flaps were used for secondary reconstruction, and gave satisfactory results with no signs of recurrence or severe scarring at the donor site.
