Tip Defects Research Articles

Multiple Y-V plasty.

Webs and contracture, whether congenital or the result of trauma or surgical excision, have been resurfaced with local tissue utilizing the principle of multiple Y-V advancement flaps. Initially the procedure was used in releasing broad scar contracture following a burn wound of the torso, and for congenital soft tissue shortening of the dorsum of the foot, both with gratifying results. The procedure was later used to obtain adjacent soft tissue for resurfacing defects of the nasal tip or ala, resulting from trauma and following the excision of a tumor. (For example, it enabled us to compensate for a rotation flap defect.) It is also useful for additional release of scar contractures of the digits and extremities after transposition of Z-plasty flaps, which can be further advanced using the Y-V advancement principle.

Reconstruction of Nasal Tip Defect

SummaryOur experience with nasal tip reconstructions using angular mid line forehead flap is presented. This flap has been shown to be better because it provides additional length.

The Nasal Dorsum Flap

Closure of full-thickness defects of the nasal tip and sorsum requires both a satisfactory functional and an acceptable cosmetic result. The nasal dorsum flap is particularly well suited for closure of many such defects. The basic design of the flap, as well as several useful modifications, are discussed.

Der ?bi-lobed flap? in der Kopf- und Halschirurgie

Esser described in 1918 a bi-lobed flap for reconstruction of a nose tip defect. We use this flaps nowadays to close little defects in nose, cheek and lip region. If we have to close large defects we use large “bi- and tri-lobed flaps”, if necessary we use the large regional flaps of neck, shoulder and thorax in this way.

Influence of tip defects on flank wear in hard-metal tools used in steel turning

The influence on flank wear of a small cutting-edge defect in carbide tips was investigated in the rough turning of steel. Results are given describing the effects of different geometric parameters of the defect on the local and average width of the wear land.

Neurovascular island pedicle flaps for terminal amputations and digital scars

Summary A volar island pedicle flap supplied by double neurovascular bundles is described in the treatment of terminal amputations and digital scars. Its use in selected cases is recommended including also elimination of anisthetic areas in the distal pulp region. Large flaps can be used for extensive digital tip defects and the method is applicable to multiple digital tip injuries.

CONTRIBUTIONS TO PLASTIC SURGERY DURING 1946

THREE articles among the numerous contributions on nasal plastic surgery in 1946 are of special importance: Brown and Cannon's review of operations in which composite grafts of skin and cartilage were used in the reconstruction of defects of the ala, Straith's presentation of the Z plastic procedure for elongating the columella, and Dupertuis' original contribution in which he describes how he successfully used composite grafts of skin and fat taken from ear lobes in the reconstruction of defects of the nasal tip and ala. Increasing evidence was presented indicating that the plastic surgeon should use autogenous cartilage and bone grafts whenever possible in preference to preserved cartilage, which is inferior grafting material. Experimental work with young human cartilage demonstrated growth of this cartilage following transplantation. Plastic surgeons are avoiding the use of living maternal ear cartilage and maternal rib cartilage for the reconstruction of a complete auricle. Cadaver cartilage is
