Single Layer and Double Layer Duraplasty for the Management of Persistent Cerebrospinal Fluid Rhinorrhea Following Frontal Sinus Trauma: A Retrospective Study.

Persistent cerebrospinal fluid (CSF) rhinorrhea is an infrequent complication of frontal sinus trauma. It often require craniotomy for dural repair and obliteration of sinus with well vascularized pericranial flap. The multilayer vascularized techniques have gained popularity over the years owing to low rate of postoperative CSF leaks.

Effect of low level laser therapy on crestal bone levels around dental implants-A pilot study.

Background: Implant success is affected by initial bone resorption at the implant surface. Continuous efforts have been made to reduce the peri-implant crestal bone loss. Limited information is available regarding the influence of low level laser therapy (LLLT) on interaction between the bone and implant surface.
