The effectiveness of sinus ventilation is due to a regular anatomy of inner nose structures such as the maxillary sinus ostium. With the aid of nose and sinus manometric measurements, it is possible to show that better functional results can be achieved using a conservative surgical technique. The present study compared 30 patients subdivided in two groups. Group A underwent conservative endoscopic sinus surgery whereas group B was operated on using non-conservative endoscopic sinus surgery. Thirty days later, both groups underwent a manometric survey of the maxillary sinus ostium by means of the digital manometry system. The pressure values obtained by nasal and sinus manometry in Group A or Group B patients were referred to those obtained in a Standard Group without nasal-sinus pathologies, calculating a percentage index of functional efficacy (maxillary sinus functional efficacy). The average percentage of the maxillary sinus functional efficacy was 98,35 percent for group-A patients, and 49,73 percent for group-B patients. Student t test revealed a statistical difference only between group B patients and standard group patients (p less than 0.4).

Abstract

The effectiveness of sinus ventilation is due to a regular anatomy of inner nose structures such as the maxillary sinus ostium. With the aid of nose and sinus manometric measurements, it is possible to show that better functional results can be achieved using a conservative surgical technique. The present study compared 30 patients subdivided in two groups. Group A underwent conservative endoscopic sinus surgery whereas group B was operated on using non-conservative endoscopic sinus surgery. Thirty days later, both groups underwent a manometric survey of the maxillary sinus ostium by means of the digital manometry system. The pressure values obtained by nasal and sinus manometry in Group A or Group B patients were referred to those obtained in a Standard Group without nasal-sinus pathologies, calculating a percentage index of functional efficacy (maxillary sinus functional efficacy). The average percentage of the maxillary sinus functional efficacy was 98,35 percent for group-A patients, and 49,73 percent for group-B patients. Student t test revealed a statistical difference only between group B patients and standard group patients (p less than 0.4). Patients submitted to a more aggressive endoscopic approach showed inadequate sinus ventilation when compared to the standard reference group.
