background and aims. wound dehiscence after lower third molar surgery extends the postoperative treatment period and may cause long-standing pain. the aim of this study was to compare wound dehiscence after removal of wisdom teeth in the most prevalent mandibular impaction (mesioangular class ib) by two different soft tissue flap designs. materials and methods. partially-erupted mandibular thir...

Objective To evaluate the efficacy and complications of a novel surgical technique for cicatricial lower lid ectropion that uses a vertical-to-horizontal (V-to-H) rotational myocutaneous flap procedure (Tsai procedure). Methods We performed the V-to-H rotational myocutaneous flap procedure on 20 eyelids in 20 patients with mild to moderate cicatricial lower lid ectropion. A vertical myocutane...

BACKGROUND The purpose of this study was to determine whether patients with a poor prognosis for survival were more likely to undergo reconstruction with a pectoralis flap versus a free flap and whether the use of a pectoralis flap offered any perioperative advantage, such as a reduction in medical complications. METHODS Fifty-five consecutive patients who underwent immediate reconstruction a...

The structure of the sheep cervix limits the application of reproductive biotechnologies such as embryo transfer and artificial insemination. The aim of this study was to determine differences in cervical anatomy and morphology between Sanjabi lambs and ewes, and the relationship between cervical anatomy and cervical penetration in ewes. Four hundred and sixty eight postmortum cervices belongin...

INTRODUCTION The adoption of vascular pedicled flaps to reconstruct skull base defects following endoscopic endonasal skull base surgery is a significant milestone in the development of endoscopic endonasal approaches (EEAs). In 2006, Hadad and Bassagaisteguy introduced the pedicled nasoseptal flap (NSF). The NSF decreased initial postoperative cerebrospinal fluid (CSF) leak rates from >20% to ...

PURPOSE The purposes of this study are to determine if there is a difference in the papilla fill between implant and teeth comparing immediate provisionalized and delayed single tooth implant restorations, and to determine the relationships between the vertical and horizontal bone levels to papilla filling the inter-dental region with single implant restorations. PATIENTS AND METHODS Two grou...

Base excision repair can proceed in either one of two alternative pathways: a DNA polymerase beta-dependent pathway and a proliferating cell nuclear antigen (PCNA)-dependent pathway. Excision of an apurinic/apyrimidinic (AP) site by cutting the phosphate backbone on its 3' side following incision at its 5' side by AP endonuclease is a prerequisite to completion of these repair pathways. Using a...

Purpose: The eyelid is commonly dissected and divided in the process of, for example, blepharotomy, entropion repair, or when preparing a full-thickness eyelid flap to reconstruct a tumor defect. No study has yet been conducted to examine how perfusion in an eyelid is affected by dissection, using modern imaging techniques. Methods: The eyelid was divided with a 10-mm vertical incision, 5 mm fr...
