Objective  To observe the application effect of modified nasal cavity tamping system in elderly patients (≥60 years old) after functional endoscopic sinus surgery (FESS).

  Methods  A total of 72 patients treated with FESS were selected as study subjects. According to different tamping of nasal obstruction, they were divided into study group (modified nasal obstruction system, 38 cases) and control group (expanded sponge, 34 cases). Systolic pressure and heart rates were compared 1 h before surgery and 6 h after surgery in the two groups. Systolic pressure, blood oxygen saturation (SpO₂), heart rate, Visual Analog Scale (VAS) score and nasal blood loss conditions were recorded 6 h after surgery in the two groups. Pain degree, blood loss, and Lund-Kennedy scores were compared between the two groups at 1 month and 3 months postoperatively.

  Results  At 6 hours after operation, the systolic pressure and heart rate in the study group showed no significant differences when compared with those before operation (P>0.05), while the systolic pressure and heart rate in the control group were significantly higher than before operation (P < 0.05). The systolic pressure and heart rate in the study group were lower and SpO₂ was higher than those in the control group (P < 0.05). The proportions of patients with mild and moderate nasal distending pain and discomfort sensation 6 h after surgeryin the study group were higher than those in the control group, the proportions of patients with severe nasal distending pain and discomfort were lower than that in the control group (P < 0.05). The proportions of patients with mild and severe nasal pain were higher in the study group than those in the control group, and the proportions of patients with moderate pain were lower than those in the control group (P < 0.05). At 6 h after operation, there was no significant difference in the severity of the bleeding sides of the nasal cavity between the two groups (P>0.05). The proportions of moderate and severe bleeding sides in the study group were lower than those in the control group (P < 0.05).

  Conclusion  The modified nasal filling system used for postoperative nasal endoscopic filling in the elderly can improve postoperative pain and nasal congestion, and significantly reduce the risk of occurrence of cardiovascular and cerebrovascular diseases caused by postoperative pain and discomfort.
