Anatomical and Surgical Findings and Complications in 100 Consecutive Maxillary Sinus Floor Elevation Procedures

An Alternative Maxillary Sinus Lift Technique – Sinu Lift System

“…CT Scans did not reveal any mucosal thickening, air fluid levels or opacifications postoperatively. Naso endoscopy or nasal decongestants are not necessary since only patients without sinus problems and with no radiographic evidence of sinus pathology were included for the study [7]. This was probably the result of a meticulous surgical protocol and patient selection and the minimal invasiveness of the sinu-lift system.…”

“…The most commonly used approach, the lateral window technique had potential complications like membrane perforation (11-56%), tearing of the membrane, bleeding, infection, and sinus obstruction [7].This technique requires considerable surgical skill and time and also often giving rise to unpleasant sequelae such as edema and discomfort. A less invasive alternative was introduced by summers known as the osteotome or bone added osteotome sinus-floor elevation (BAOSFE) technique, but it has been shown to yield only a modest increment in bone height of only 3±0.8 mm [17].…”

“…Though good implant survival rates are being reported with these procedures, the postoperative morbidity was noticed to be higher with these techniques [7]. Hence, modifications of these techniques have been suggested by various authors and thus the 'Minimally invasive Techniques' have come to stay [8,9].…”

First report of an acute purulent maxillary sinusitis caused by Pseudomonas aeruginosa secondary to dental implant placement in an immunocompetent patient

“…Although these infections affect a large portion of the population, and can produce serious complications if not treated quickly and adequately, few epidemiological and clinical studies have been reported in the literature. [1][2][3] Pseudomonas aeruginosa infection following dental treatment, though not frequent, is well described in the immunocompromised population, including the elderly, organ transplant recipients, HIVinfected patients, cancer patients, and those on immunosuppressive therapy. 4,5 It is, however, very uncommon in immunocompetent patients.…”

Septum en Seno Maxilar: Un Estudio de 91 Cirugías Consecutivas de Elevación de Piso Sinusal

“…La etapa de descolamiento de la membrana es una de las más críticas debido a que gran parte de las complicaciones asociadas a la laceración de membrana sinusal se producen en ese momento. La presencia de variaciones óseas intrasinusales fue descrita inicialmente por Underwood en el año 1910 en su trabajo clásico, donde destaca la morfología y fisiología del seno maxilar, su desarrollo y sus condicionantes para el desarrollo de patologías (Underwood, 1910); sin duda que la presencia septum intrasinusal y otras variaciones anatómi-cas puede dificultar la cirugía (Zijderveld et al, 2008), limitando la efectividad del procedimiento. Existen algunos estudios que señalan la presencia de septum intrasinusal en 111 de 400 senos maxilares evaluados mediante tomografía cone beam, señalando también que la posición media fue la más prevalente (45,9%) seguida de la región posterior (31,5%) .…”
