Samy Elian, Khaled Barakat
Closed sinus lifting is a unique technique in being simple and less invasive (Summers, Compendium 15(6):698, 1994). However, it is blind to assess the safety of sinus lining during lifting without perforation. Previously, sinus membrane was assessed endoscopically in an invasive way. We aimed to judge clinically the sinus membrane integrity after crestal elevation by a direct simple less invasive endoscopic visual assessment through the crestal osteotomy site. To confirm undetected perforation, the sinus membrane was monitored dynamically by introducing the endoscope through a trephined opening in the lateral wall of the sinus (Nkenke et al...

The potential application of stem cell biology in human dentistry is a new and emerging field of research. The objective of the current review was to study the efficiency of mesenchymal stem cells (MSCs) in sinus lift augmentation (SLA). A literature review was performed in PubMed Central using MeSH keywords such as sinus lift, MSCs, dental implants, and augmentation. The searches involved full-text papers written in English, published in the past 10 years (2007-2017). The review included in vitro and in vivo studies on the use of MSCs in SLA...

The aim of this review was to test the hypothesis of no difference in the efficacy of bone regeneration when using stem cells in maxillary sinus floor augmentation surgery in comparison to other grafts. Nine randomized clinical trials and one follow-up study involving human subjects were identified through a search of the PubMed/MEDLINE, Scopus, Cochrane, and Web of Science databases, supplemented by a hand search. No significant difference between groups was found for the implant survival rate, increase in bone height, marginal bone loss following implant placement, or new bone formation...

The demand for facial feminization is increasing in transsexual patients. Masculine foreheads present extensive supraorbital bossing with a more acute glabellar angle, whereas female foreheads show softer features. The aim of this article is to describe our surgical technique for fronto-orbital feminization. The mask-lift technique is an upper face-lift. It provides rejuvenation by correcting collapsed features, and fronto-orbital feminization through burring of orbital rims and lateral canthopexies. Depending on the size of the frontal sinus and the thickness of its anterior wall, frontal remodeling is achieved using simple burring or by means of the eggshell technique...

Sinus membrane elevation can be accomplished through use of either a direct or indirect technique. The indirect or internal elevation technique lifts the sinus membrane by elevating it superiorly using osteotomes, with or without the use of grafting material. The authors reference a revolutionary randomized clinical trial in which tissue-level implants with a coronally flared design were placed in residual bone height of ≤4 mm using an internal sinus membrane elevation technique and describe an adaptation of the procedure discussed in that study and its successful use in a prosthodontics residency program...

During a sinus lift procedure the main requirement in order to position an implant is to have a maxillary sinus floor cortical bone thick enough to guarantee a primary stability in the implant inserted. In this way, the healing process is facilitated and osseointegration of the titanium surface may occur simultaneously, thus reducing the waiting time for the engraftment of the implant into the body. Unfortunately, these conditions are not always present. Hence, the need of developing an alternative approach that could simultaneously allow to perform sinus floor elevation along with an implant placement...

This case describes the successful long-term outcome of a patient's treatment after a restorative failure occurred soon after delivery. The esthetic and restorative treatment has been successful for nearly a decade due largely to a careful, objective evaluation of all possible causes of the restorative failure. The treatment plan for the patient, who was assessed as high risk biomechanically and functionally, was carried out in the following phases: (1) an implant placement that required an osteotome sinus lift; (2) placement of feldspathic bonded veneers for the maxillary anterior teeth to minimize removal of tooth structure; (3) numerous core-supported restorations, with fixed partial dentures placed for teeth Nos...

The video-assisted subcutaneous destruction of the sinus tract (VADST) is a novel, minimally-invasive technique for the treatment of pilonidal sinus disease (PSD). This is an advancement of the previously described subcutaneous destruction of the sinus tract and the removal of hairs as well as the long-term vessel-loop drainage of the wound channel (DST). Although the first results of this operation seemed to be promising, some of my colleagues felt that the blind approach to this procedure could be its potential "weak point"...
