maxillary sinus graft

Sung-Ho Shin, Hyun Seok, Seong-Gon Kim, Seong-Doo Hong
Sinonasal mucosal melanoma (SNMM) in the maxillary sinus is a rare disease condition. Compared to oral mucosal melanoma, SNMM has a bulky, exophytic, and polypoid appearance, is weakly pigmented, and associated with unspecific symptoms. Due to these features, SNMM in the maxillary sinus has been misdiagnosed as nasal polyps and chronic sinusitis. In this case report, we described SNMM occurring in the right maxillary sinus simulated as a cystic or benign lesion. Cortical bone thinning and expansion were observed around the mass...

Isolated orbital wall fractures account for 4% to 16% of all facial fractures. Even a modest change in the position of the bony walls can have a significant impact on orbital volume and globe position. Alloplastic materials or autogenous bone grafts such as the antral maxillary wall can be used to reconstruct small- to medium-size orbital fractures. The main advantage of an antral wall graft is the intraoral approach with minimal morbidity. Nine patients underwent repair of orbital floor fractures using the extraoral and the intraoral antral wall approach...

Maxillary sinus antrolithisis is a rare finding. Conservative surgical removal recommended. In the patients that need to maxillary intrasinus augmentation and antrolith is observed in preoperative radiography, 2 options remain. First, doing Caldwell-luc surgery to remove antrolith and delayed open sinus lift. Second way is removing antrolith and concomitant intrasinus augmentation.The first way has 2 disadvantages: prolonged waiting period and difficulty of open sinus lift in sinuses with scar and fibrosis...

In this article, a novel endoscopic technique used to close oro-antral fistulas will be described. In the technique described here, 24 cases were surgically treated between May 2011, and November 2014. Under endonasal endoscopic examination following partial inferior uncinectomy, the natural ostium of the maxillary sinus was identified; through this tract, a curved aspirator was advanced into the sinus. If present, we extracted endoscopically tissues causing obliteration of the ostium through the Caldwell-Luc antrostomy, taking care to preserve the integrity of the natural ostium...

Bone substitutes are used as alternatives for autologous bone grafts in patients undergoing maxillary sinus floor elevation (MSFE) for dental implant placement. However, bone substitutes lack osteoinductive and angiogenic potential. Addition of adipose stem cells (ASCs) may stimulate osteogenesis and osteoinduction, as well as angiogenesis. We aimed to evaluate the vascularization in relation to bone formation potential of the ASC-containing stromal vascular fraction (SVF) of adipose tissue, seeded on two types of calcium phosphate carriers, within the human MSFE model, in a phase I study...

Treatment of severe maxillary atrophy with implants has achieved important successes in recent years. The limit of implant insertion is related to inadequate bone quantity (i.e. height and width). Alveolar bone grafting, sinus lifting and major grafting via Le Fort I osteotomy have used in the past to restore bone volume prior of implant insertion. However successes do not always occur and a second stage surgery is necessary in most cases. Immediate loading cannot be performed in all grafted bone. In recent years a new treatment approach has been proposed by using zygomatic implants...

Objective: Sinus floor elevation with lateral approach is probably the most frequently performed reconstructive procedure to rehabilitate posterior maxilla when a bone deficiency is present. Different graft materials have been proposed and tested, often with high clinical performances and predictable results. Histological analysis is required when evaluating new materials. We investigated human biopsies retrieved after sinus floor elevation procedure by histomorphometric evaluation to test the performance of an equine-derived bone grafting material...

Background: Displacement of dental implants into the maxillary sinus is rare, but it primarily occurs in patients with severe pneumatization of the maxillary sinus and/or deficiency of the alveolar process. Some complications such as the infection of the paranasal sinuses and formation of the oroantral fistula can be followed by the displacement of a dental implant. Therefore, the displaced implant has to be removed immediately with surgical intervention show and another plan for rehabilitation should be considered...

In the context of the trans crestal maxillary sinus lift, a wide variety of biomaterials have been used to fill the sub-antral space over the years. The materials that have a pasty consistency and are smooth and free from lumps are the most suitable to come into contact with the Schneiderian membrane which, if torn, cannot perform its graft containment function. In this study, a micronized heterologous bone in a collagen matrix of two different percentages was used in order to fill the maxillary sinus. Before using biomaterial as filler, a spray form of hyaluronic acid was used to disinfect the surgical site before and after the surgery, along with more consistent and pasty form of gel of hyaluronic acid being used in order to facilitate the detachment of the membrane...
