BACKGROUND The long-term stability of maxillary sinus floor augmentation with β-TCP remains largely unknown. We report the long-term assessment of volumetric changes in maxillary sinus floor augmentation with β-TCP by cone-beam computed tomography (CBCT). METHODS The subjects included 30 patients who underwent maxillary sinus floor augmentation using β-TCP and 58 implant placement for unilate...

The growth pattern of the maxillary sinus was analyzed using 18 human fetuses of both sexes between 9 and 21 weeks of age postconception. The paraffin embedded specimens were cut in series in the frontal and the transversal plane, respectively. The inner surface of the maxillary sinuses was redrawn and surrounded with a digitizer and then the volumes were calculated. A correlation analysis as w...

We present a case of a 59-year-old man with left upper alveolar numbness of 2 years' duration in the absence of sinonasal symptoms. On physical examination, he demonstrated mild left facial asymmetry and diminished sensation of his left upper alveolus from the left second upper incisor to first canine. CT imaging revealed chronic sinusitis changes of the left maxillary sinus, with reduced volum...

OBJECTIVES The posterior maxillary region often provides a limited bone volume for dental implants. Maxillary sinus elevation via inserting a bone graft through a window opened in the lateral sinus wall has become the most common surgical procedure for increasing the alveolar bone height in place of dental implants in the posterior maxillary region. The purpose of this article is to assess the ...

introduction: atypical infratemporal fossa infections are rare and potentially fatal.   case report: a case of an aspergillosis localized in the infratemporal fossa and another case of tuberculosis of the infratemporal fossa originating from the maxillary sinus, is described. the first patient was immunocompromised and showed symptoms of facial numbness; whereas the other was an immunocompetent...

Purpose. Gender determination is considered to be an important step in the reconstruction of the biological profile in forensic medicine. Maxillary sinus can be used for identification of sex when other methods are indecisive. Computed tomography (CT) provides an excellent method for examining maxillary sinuses. Hence the aim of the study was to determine the accuracy of gender determination us...

One of the most challenging and technically sensitive surgical procedures in conjunction with dental implant rehabilitation is sinus membrane lifting to increase the bone height or volume from the maxillary sinus floor. This important preprosthetic surgical technique has been available for >15 years, making possible the creation of bone volume in the edentulous posterior maxilla for the placeme...

PURPOSE Implant placement in the posterior maxilla may often be contraindicated because of insufficient bone volume and the presence of the maxillary sinus. In these situations, sinus floor lifting and grafting frequently have been proposed as the best treatment. The aim of this study was to compare histologically the use of 100% autogenous bone versus a combination of autogenous bone and corti...

BACKGROUND The aim of the study was to assess if the presence of nasal septal deviation and concha bullosa is connected with the development of sinuses and the incidence of inflammation within them. MATERIAL/METHODS We retrospectively analysed 214 patients who underwent paranasal sinus computed tomography. There were 125 females and 89 males, the mean age being 47.67±16.74 years (range 18-97)...
