Abstract BACKGORUND. Sinus floor elevation, also known as sinus lift, is the surgical procedure meant to elevate the maxillary floor in order to increase the height of the alveolar bone. This will allow the oral surgeon specialist to insert the desired implants, the ground of dental reconstruction. As the procedure involves the maxillary sinus and its Schneiderian membrane the main concern is to have a healthy maxillary sinus prior to implantation and to the maxillary augmentation. OBJECTIVE. The aim of our study was to identify the patients with abnormal CT scan and refer them to an ENT evaluation, in order to identify and treat any sinusal pathology that can lead to a poor outcome of the sinus-lift intervention. MATERIAL AND METHODS. Our prospective study included 15 patients selected from a group of 79 adults, candidates for dental implantation with sinus augmentation. These patients had abnormal sinus CT scan in terms of mucosal hypertrophy, cysts or fungal material. Transnasal diameatic sinusoscopy was performed for all the patients, assessing the aspect of the sinus cavity and the mucosa. The following abnormal aspects were found in our group: 5 patients with cysts, 2 patients with fungus ball and 4 with mucosal hypertrophy. 4 patients had normal maxillary mucosa despite the CT scan appearance. RESULTS. All the patients with abnormal aspects at sinusoscopy (11 patients) were operated on before sinus lift procedure - antrostomy, cyst removal, fungus ball removal. 4 patients showed normal aspect of the sinus mucosa despite the CT scan donations, meaning a 26.66% error rate in appreciating the real changes of the maxillary mucosa on the CT scan. CONCLUSION. Endoscopic assessment of the maxillary sinus is mandatory in patients with changes of the CT scan. This allows a proper examination of the sinus mucosa and can predict the outcomes of the sinus lift procedures. It is mandatory to cure the inflammation or infection of the maxillary sinus prior to implant procedure in order to be able to increase the success rate, as it can lead to failures of the implant procedure.

The procedure of crestal maxillary sinus floor elevation presents a great challenge to the field of implant dentistry. Due to the limited visualization in this procedure, the effectiveness of detaching sinus mucosa could not be assessed in real time. We recently developed an ex vivo goat sinus model by cutting the goat residual skulls along four lines determined from computerized tomography (CT) scans, extracting the maxillary premolar or molar teeth, and preparing implant socket in the maxilla. The generated ex vivo goat sinus models exposed the maxilla and the whole maxillary sinus mucosa, thus enabling real-time observation of detaching maxillary sinus mucosa via directly visualizing the working situation of sinus lift tool in the models and directly measuring the length of detached mucosa and space volume generated under the elevated sinus mucosa. One commercially available umbrella-shaped sinus lift curette was used to detach the maxillary sinus mucosa to evaluate the effectiveness of the ex vivo goat sinus models. The results showed that this curette could detach the sinus mucosa 3.75 mm in length in the mesiodistal direction and 2.81 mm in the buccal-palatal direction. Moreover, a space volume of 52.7 μl could be created under the elevated sinus mucosa in the goat ex vivo models. All the experimental results suggested that this ex vivo goat sinus model might be useful in the evaluation of improved or newly designed sinus lift tools for elevating the maxillary sinus mucosa via the crestal approach.

SummaryIntroduction. An enforcement of atrophic maxilla with biomaterials during sinus-lift surgery improves size and quality of alveolar bone. Radiological densitometric analysis can prove it. Within the study a density of bone was investigated and findings were compared with natural bone around the implants.Aim of the Study.Was to determine if density around the implant inserted with one stage sinus-lift operation using bone substitute materials increase and if that can be detected radiologically.Materials and Methods.Totally there were examined 22 patients where 64 implants were inserted in maxilla: 48 implants were inserted with one stage sinus-lift operation using bone substitute materials; represented study group. Sixteen implants were inserted in natural maxillary alveolar bone of the same patients, representing control group. The density of implant supporting tissue was measured with cone beam computed tomography and expressed in Hounsfield units (HU). The measurements were performed according to standardized pattern.Results.Densitometric measurements were higher in the study group than in the control group in all points, but statistically significant difference was observed in two measurement sites: buccally in sinus elevation area (BSM) (p=0.005) and palatinally in sinus elevation area (PSM) (p=0.0012), and corresponding areas in control group.Conclusions.Surgical elevation of maxillary sinus floor using calcium phosphate bone substitute materials resulted in higher optical density compared to natural bone. Mineralization of the bone, induced by the bone substitute materials, can be detected radiologically

Implant rehabilitation of the edentulous posterior maxilla may be a challenging procedure in the presence of insufficient bone volume for implant placement. Maxillary sinus augmentation with or without using grafting materials aims to provide adequate bone volume. The aim of the present study was to systematically review the existing literature on transalveolar maxillary sinus augmentation without grafting materials and to propose and describe an osteotome-mediated approach in postextraction sites in combination with platelet derivative. The systematic review showed that high implant survival rate (more than 96% after 5 years) can be achieved even without grafting the site, with a low rate of complications. Available alveolar bone height before surgery was not correlated to survival rate. In the described case report, three implants were placed in posterior maxilla after extraction of two teeth. An osteotome-mediated sinus lifting technique was performed with the use of platelet derivative (PRGF); a synthetic bone substitute was used to fill the gaps between implant and socket walls. No complications occurred, and implants were successfully in site after 1 year from prosthetic loading. The presented technique might represent a viable alternative for the treatment of edentulous posterior maxilla with atrophy of the alveolar bone though it needs to be validated by studies with a large sample size.

<p class="p1"><span class="s1">In order to increase the bone height in the distal portions of the maxilla during dental implantation the method of «closed» sinus lift is widely applied. Manipulation is considered to be a minimally invasive osteotomy but despite this fact, it is associated with a high complication rate that might lead to the loss of the dental implant. </span></p><p class="p1"><span class="s1">The purpose of the project is to analyze the evaluation of the effectiveness of immunomodulators local application during the "closed" sinus lift manipulation that is based on local in uence of «Betaleukin» and «Roncoleukin» drugs in the area of unexpected perforation of the mucous membrane of the maxillary sinus during the formation of the bone bed and close contact surface of the implant with a damaged part. A clinical randomized trial was held which of 105 patients aged 30 to 57, divided into three groups: comparison group, n = 35 (implants placed by the closed sinus lift standard method); betaleukin group, n = 35 (in addition to the surgery performed local recombinant IL-1β immunotherapy was conducted); roncoleukin group, n = 35 (the surgery done was combined with the local ronkoleukine immunomodulation). Within 10-12 days after the surgery hydrogel «Koleteks-Beta» and a gel containing recombinant IL-2 for a local effect on the oral mucous membrane around the installed implant were applied. During the study, all patients had a number of clinical signs that allow assessing the dynamics of post-operative course of the integration process of implants. Radiological control in the postoperative period was conducted to evaluate the position of the implant in relation to the maxillary sinus; the dynamics of bone tissue around it was observed. It was found out that the local treatment by immunomodulators improves the performance dynamics of clinical postoperative period; it reduces the risk of graft rejection and increases the ef ciency of integration process. </span></p>

The aim of this pilot study was to present a novel technique for the management of the Schneiderian membrane during maxillary sinus lift surgery using plasma rich in growth factors (PRGF). Eight maxillary sinuses were augmented in 8 patients. Two small perforations of the Schneiderian membrane occurred during the lifting procedure, which were solved using the PRGF clot before grafting the site with PRGF and anorganic bovine bone. With the exception of 1 patient who experienced pain following an acute sinus infection after 3 days of uneventful healing, the patients' postoperative quality of life was generally good. The most common complication (50% of cases) was hematoma, which disappeared after 1 week. Despite the limitations of this study concerning the sample size and the study design, the use of PRGF may be helpful in reducing complications following sinus lift surgery. More well-designed studies, with larger sample size, are needed to validate this protocol.

Abstract Objective: We aimed to explore the expression and interplay of NO and iNOS to elucidate their roles in human maxillary sinus mucosa with maxillary sinus fungus ball (MSFB) and chronic rhinosinusitis (CRS).Methods: Fifty-one patients with MSFB, CRS and simple maxillary sinus cyst were included in this study. The NO content of the mucosa of each group was detected by Nitric acid reductase method. The expression of iNOS was tested by immunohistochemistry and Western blott. Spearman correlation analysis was used to analyze the correlation between the expression of iNOS and the occurrence of MSFB and CRS.Results: The results showed that NO and iNOS were highly expressed in the maxillary sinus mucosa of MSFB group, which were significantly different from CRS and control group (P<0.01). The expressions of NO and iNOS in the samples of CRS group were higher than that of the control group (P<0.05). Moreover, iNOS was widely presented in the cytoplasm of sinus mucosa epithelium and inflammatory cells in the maxillary sinus mucosa of MSFB patients. Furthermore, Spearman correlation coefficient indicated that the expression of iNOS was positively correlated with the incidence of MSFB (r=0.6395, P<0.05).Conclusion: NO and iNOS are overexpressed in the maxillary sinus mucosa of MSFB and CRS patients, and the increase in the MSFB patients was better than the CRS. The expressions of NO, iNOS were also correlated with the incidence of MSFB. We thus provide a new indicator to assist the diagnosis of MSFB and its distinction from CRS.

This study was carried out to evaluate the prevalence of sinus mucosa perforation occurred during maxillary sinus mucosa elevation surgery, its relation to objective conditions and to the causative medical history, and its influence on postoperative sinusitis, as well. One hundred and forty-six sinus lift procedures have been evaluated in 118 patients. The prevalence of the sinus mucosa perforation was evaluated and subdivided into four groups according to its size and way of treatment. No relation was observed between the perforation and the presence of sinus septa, smoking, radiographic thickening and cyst-like lesions of the maxillary sinus, and previous sinus allergy (P<0.05). Despite of high prevalence of the perforation of the mucosa (56.16%), no signs of bone graft infection or maxillary sinusitis were noted in any of our patient.
