[Neural Reconstruction for Facial Nerve Palsy].

The basic techniques of nerve reconstruction surgery for facial nerve palsy are end-to-end nerve suture and end-to-side nerve suture. The latter has the epineural window method and the partial neurectomy/neurotomy method for the treatment of "side" nerves. Hypoglossal-facial nerve cross-link graft is a method of nerve reconstruction in which the hypoglossal and facial nerves are bridged by autologous nerve transposition with end-to-side nerve suture.

Modified Lengthening Temporalis Myoplasty Involving an Extended Lazy-S Incision to Avoid Facial Scar Formation.

Background: Lengthening temporalis myoplasty is a faster and less invasive alternative to free muscle transfer for smile reconstruction. However, it requires a nasolabial fold incision, which leaves a midfacial scar. Based on esthetic considerations, a modified approach, involving an extended lazy-S (parotidectomy) incision instead of a nasolabial fold incision, was developed.

Vein/Arterial Grafts Harvested within the Incision for a Free Groin Flap.

The free groin flap results in less donor-site morbidity than other skin flaps and is suitable for use in children and adolescents. However, the vascular pedicle is relatively short and vessel diameter is small, which makes vascular anastomosis technically difficult. To overcome this limitation, we harvested vein and arterial grafts from the flap elevation area without placing additional skin incisions.

Round cell liposarcoma arising in the left foot: MRI and PET findings.

Liposarcomas are one of the most common soft-tissue sarcomas and commonly arise in the deep soft tissues of the extremities and retroperitoneum; however, the occurrence of liposarcomas in the foot or ankle is exceedingly rare. In this article, we present a 52-year-old man with round cell liposarcoma arising in the left foot. This tumor presented unusual manifestations of secondary osseous involvement in the metatarsal and tarsal bones of the left foot and solitary lymph node metastasis at the para-aortic region.

Proliferating pilomatricoma: a subset of pilomatricoma.

Proliferating pilomatricoma is a histopathological entity that was proposed by Kaddu et al. in 1997. Proliferating pilomatricoma represents a distinctive histopathological entity; it should be differentiated from other benign and malignant neoplasms with features of hair matrix differentiation.

Repair of scalp defect using a superficial temporal fascia pedicle VY advancement scalp flap.

Repair of scalp defects using a superficial temporal fascia pedicle VY advancement scalp flap, which is supplied by superficial temporal vessels, is reported. This method has been used in seven cases of scalp defects, and enables us to provide primary closure of the defects with hair-bearing scalp skin. This method is simple, easy, and reliable.

Neurovascularized free short head of the biceps femoris muscle transfer for one-stage reanimation of facial paralysis.

The single-stage technique for cross-face reanimation of the paralyzed face without nerve graft is an improvement over the two-stage procedure because it results in early reinnervation of the transferred muscle and shortens the period of rehabilitation. On the basis of an anatomic investigation, the short head of the biceps femoris muscle with attached lateral intermuscular septum of the thigh was identified as a new candidate for microneurovascular free muscle transfer. The authors performed one-stage transfer of the short head of the biceps femoris muscle with a long motor nerve for reanimation of established facial paralysis in seven patients.

Nasal augmentation using calcium phosphate cement.

This report describes a simple technique for augmentation rhinoplasty using calcium phosphate cement paste for postoperative and posttraumatic nasal deformities. This biomaterial was used to correct traumatic nasal bone deformity in one patient and for augmentation rhinoplasty after removal of the nasal implant in two patients. These patients were followed for a minimum 6 months and a maximum of 26 months.
