For reconstruction of small full-thickness defects of the ala, the nasolabial...

OBJECTIVES Defects after endoscopic expanded endonasal approaches (EEA) to the skull base, have exposed limitations of traditional reconstructive techniques. The ability to adequately reconstruct these defects has lagged behind the ability to approach/resect lesions at the skull base. The posteriorly pedicled nasoseptal flap is our primary reconstructive option; however, prior surgery or tumors...

Gingival recession can result in an unesthetic appearance, hypersensitivity, and root caries. The physiological well-being of the patient is a significant factor associated with the success of dental therapy. Esthetics is one of the main concerns of the patient if recession is present especially in anteriors. Hence, the treatment of choice for root coverage for the anterior teeth should address...

Background and objectives: Perforator flaps, both pedicled and free flaps, are increasingly used in reconstructive surgery. However, the microvascular perfusion pattern within these flaps still remains essentially unknown. It is well known that in random-pattern flaps, flap length correlates directly with the width of the flap base. In perforator flaps, the importance of preserving a skin base ...

Three-dimensional architecture of vasculature and nephrons in rat renal papilla was assessed by digital reconstruction. Descending vasa recta (DVR), ascending vasa recta (AVR), descending thin limbs (DTLs), ascending thin limbs (ATLs), and collecting ducts (CDs) were identified with antibodies against segment-specific proteins. DTLs are distributed nonuniformly in transverse sections of papilla...

This article presents a technique for soft tissue reconstruction and covering defects associated with maxillary implant-supported restorations. A pedicle subepithelial connective tissue flap is prepared from the palatal mucosa near the area to be treated and is displaced into the receptor site. The donor site remains primarily covered. An increase in soft tissue volume is achieved at the recept...

BACKGROUND In patients with large dural defects of the anterior and ventral skull base after endonasal skull base surgery, there is a significant risk of a postoperative cerebrospinal fluid leak after reconstruction. Reconstruction with vascularized tissue is desirable to facilitate rapid healing, especially in irradiated patients. METHODS We developed a neurovascular pedicled flap of the nas...

PURPOSE The aim of this study was to evaluate alterations of papilla dimensions after orthodontic closure of the diastema between maxillary central incisors. METHODS Sixty patients who had a visible diastema between maxillary central incisors that had been closed by orthodontic approximation were selected for this study. Various papilla dimensions were assessed on clinical photographs and stu...

BACKGROUND The nasoseptal flap has revolutionized reconstruction of ventral skull base defects. The past decade is also noticeable by the evolution of transoral robotic surgery (TORS). Reconstruction of the oropharyngeal defect is challenging. Good reconstructive options with less cicatricial retraction are desirable and still lacking in the literature. METHODS Cadaver dissection and illustra...
