Effect analysis of hiatus sinus maxillaris treatment with different methods during nasal endoscope paranasal sinuses operation

Objective To explore the relationship between different treatment methods of hiatus sinus maxillaris during nasal endoscope paranasal sinuses operation and prognosis. Methods Eighty patients with chronic rhinosinusitis and rhinopolyp were divided into observation group and control group by random digits table method with 40 cases each. Expanding hiatus sinus maxillaris were given according to the modality of hiatus sinus maxillaris and lesion of maxillaris sinus in observation group. The patients in control group were given expanding hiatus sinus maxillaris. The opening rate of hiatus sinus maxillaris and postoperative complication were observed. Results All the patients were followed up ≥1 year. The opening rate of hiatus sinus maxillaris in observation group (97.5%, 39/40) was significantly higher than that in control group (77.5%, 31/40), the rate of postoperative complication in observation group (5.0%, 2/40) was significantly lower than that in control group (27.5%, 11/40), and there were statistical differences (P <0.01). Conclusion Whether or not to enlarge hiatus sinus maxillaris during nasal endoscope paranasal sinuses operation should base on intraoperative specific situation, and it can reduce intraoperative injury, prevent the shutting of sinus and postoperative complication.
