after maxillary expansion, a long period of retention is necessary to prevent early relapse. therefore, it is beneficial to accelerate bone formation in the expanding midpalatal suture to reduce relapse. this study was designed to evaluate the effect of dietary vitamin c on osteogenesis of rat midpalatal suture during expansion.fifty-four male wistar rats were randomly divided into three groups...

Intradiploic cysts in the posterior fossa are rare. We report a post-traumatic intradiploic leptomeningeal cyst in an adult and review the diagnosis and pathogenesis of this lesion. A 28-year-old woman presented with a headache and a hard mass in the occipital region. She had a history of head injury as she had fallen from a height at the age of 18 months. CT scans and MRI revealed an expanding...

Objective: To conduct a descriptive study on Hayman suture technique to control postpartum hemorrhage Method: Hayman suture was applied in 43 cases. A No-1 Vicryl suture was used on a round body or a straight needle. In 36 cases (83.72%) Hayman suture was the only intervention. In 4 cases (9.30%) uterine vessels and ovarian vessels were also ligated along with Hayman suture. In 3 cases (7%), al...

BACKGROUND The failure of sutures to maintain tissue in apposition is well characterized in hernia repairs. A mesh suture designed to facilitate tissue integration into and around the filaments may improve tissue hold and decrease suture pull-through. METHODS In vitro, the sutures were compared for resistance to pull-through in ballistics gel. In vivo, closure of midline laparotomy incisions ...

PURPOSE The purpose of this study was to test the strength of a suture capsulorrhaphy repair versus a capsulolabral repair with knotless suture anchors in a cadaveric model with anteroinferior shoulder instability. METHODS Fourteen cadaveric shoulders were tested with either a suture capsulorrhaphy to the intact labrum or a capsulolabral advancement using a knotless suture anchor into the gle...

OBJECTIVE To investigate the effects of platelet rich plasma (PRP) and fibrin sealant (FS) on facial nerve regeneration. STUDY DESIGN Prospective, randomized, and controlled animal study. METHODS Experiments involved the transection and repair of facial nerve of 49 male adult rats. Seven groups were created dependant on the method of repair: suture; PRP (with/without suture); platelet poor ...

Suture performances include handling characteristics and knot mechanical properties. These performances depend mainly on frictional, flexural, and compressive forces. The interaction between these forces developed inside the suture knot governs the displacement mode and the deformability of the suture yarn inside the knot. In the present work, we studied the effect of manufacturing conditions o...
