ABSTRACT
AIM: To investigate the efficacy and safety of dacryocystorhinostomy(DCR)through nasal endoscope with extended bone window and high ostomy in the treatment of chronic dacryocystitis.METHODS: Retrospective clinical study. A total of 50 patients(59 eyes)diagnosed with chronic dacryocystitis in our hospital from January 2018 to January 2020 were selected. They were divided into two groups according to the operation method, with 23 cases(29 eyes)in the simple stoma group and 27 cases(30 eyes)in the improved group. Patients in the simple stoma group were treated with transnasal endoscopic flat middle turbinate axillary DCR(simple stoma), and patients in the improved group were treated with transnasal endoscopic extended bone window with high-level stoma DCR. The total clinical efficiency, postoperative complication rate and satisfaction of the two groups were compared.RESULTS: The effective rate of the simple stoma group was 79% at 12mo after surgery, while that of the improved group was 97%(P=0.039). The total incidence of complications in the simple stoma group was 28%, while that in the improved group was 7%(P=0.042). The satisfaction rate of the simple stoma group was 65%, while that of the improved group was 93%(P=0.030).CONCLUSION: The treatment of chronic dacryocystitis with transnasal endoscopic extended bone window and high-level ostomy DCR further improved the efficiency of surgery and reduced the incidence of complications.
ABSTRACT
Background: Craniofacial resection (CFR) has been regarded as the gold standard for paranasal sinus and nasal cavity (PNSNC) neoplasms. The improvement of surgical procedures has been ongoing in recent years. We analyzed the clinical curative effects of the function-preservation therapy that was mainly using nasal endoscopic surgery along with appropriate radiotherapy and chemotherapy as applicable. Methods: We performed a retrospective analysis of factors that influence the survival time of the 28 patients with PNSNC neoplasms who underwent nasal endoscopic surgery. All patients with tumor lesions underwent a complete resection in en bloc or piecemeal resection. Five cases did not undergo radiotherapy or chemotherapy; the remaining 23 patients had multimodality therapy. Results: The median follow-up time was 41.5 (range = 14–97) months. The overall 3-year survival rate was 78.57% for T3 cancer and 50% for those with T4. T classification (P = 0.031) and multimodality therapy (P = 0.038) were independent prognostic factors for postoperative 3-year survival rate of patients with PNSNC neoplasms. Conclusion: Function-preservation therapy based on the minimally invasive endoscopic resection (MIER) with appropriate adjuvant therapy not only prolonged the overall survival time but also provided an opportunity to preserve organ function at the same time, which helped to improve the patients’ quality of life
ABSTRACT
@#AIM: To investigate the proportional distribution of the size of lacrimal sac in recurrent dacryocystitis after the removal of artificial nasolacrimal duct and the clinical effect of dacryocystorhinostomy under nasal endoscope on patients with recurrent dacryocystitis.METHODS: Totally 73 patients(73 eyes)with recurrent dacryocystitis after removal of artificial nasolacrimal duct in our hospital from January 2018 to November 2019 were retrospectively studied. All patients underwent dacryocystography after hospitalization, and then performed dacryocystorhinostomy combined with intubation of double- artificial nasolacrimal duct under nasal endoscope and general anesthesia. The size of lacrimal sac was measured, and the area and effective rate of fistula were analyzed respectively at 2wk, 1, 3 and 6mo after operation. RESULTS: There were 13 eyes with large dacryocyst(Transverse diameter > 5mm, 18%), 26 eyes with middle dacryocyst(Transverse diameter between 2-5mm, 36%), and 34 eyes with small dacryocyst(Transverse diameter <2mm, 47%); There was significant difference in the stoma area of dacryocystostomy at 2wk, 1, 3, 6mo respectively(<i>P</i><0.05); Compared with 2wk, 1, 3mo after operation, the stoma area at 6mo after operation significantly decreased by 14.08±0.68, 10.49±0.75, 0.31±0.23mm2(all <i>P</i><0.05); The curative rates were 100%, 93%, 88% and 85% at 2wk, 1, 3, 6mo after operation, respectively. CONCLUSION: After the removal of the artificial nasolacrimal duct, the majority of the patients with recurrent dacryocystitis typically featured medium and small lacrimal sac. The curative effect of this type of recurrent dacryocystitis by dacryocystorhinostomy and intubation under nasal endoscope was proved to be effective, which could serve as a proper and better choice in clinic practice.

ABSTRACT
@#AIM: To investigate the related factors that affect the efficacy of dacryocystorhinostomy performed with a nasal endoscope in the treatment of dacryocystitis.<p>METHODS:We retrospectively analysed the clinical data and postoperative results of 380 patients with dacryocystitis who were treated by dacryocystorhinostomy with a nasal endoscope in our hospital from July 2015 through April 2019. We observed the functional recovery of the lacrimal bursa, nasal cavity, anastomotic orifice and lacrimal passage and analysed the related factors that may affect the postoperative condition in cases of dacryocystitis.<p>RESULTS: In this study, 380 patients(413 eyes)with dacryocystitis were followed up for more than 6mo. The curative effect was measured by the function of the lacrimal passage after 6mo. Twenty-seven eyes of 27 cases(6.5%)showed no healing. The results of univariate analysis indicated that the severity of nasal septum deviation, the presence of a small lacrimal sac, repeated probing of the lacrimal passage, laser treatment or catheterization of the lacrimal passage and recurrent dacryocystitis(whether discovered in a routine revisit after the operation or in the early stage of the operation)influenced the curative effect of dacryocystorhinostomy in the patients. The results of Logistic regression analysis showed that the severity of nasal septum deviation, the presence of small lacrimal bursa and regular revisits after the operation were the main risk factors affecting the curative effect of nasal dacryocystitis under a nasal endoscope.<p>CONCLUSION: Dacryocystorhinostomy with a nasal endoscope is effective in the treatment of dacryocystitis, including difficult cases, and the postoperative cure rate is high. Skilled surgical technique, standard postoperative treatment and good compliance by patients are crucial to the success of the operation.

ABSTRACT
Objective To explore the clinical effect of nasal endoscope antrostomy treatment of maxillary sinus cyst through two approaches. Methods Eighty patients with maxillary sinus cyst were selected. The patients were divided into experiment group and control group according to the treatment method. Experiment group (40 cases) was treated through windowing middle meatus maxillary sinus associated with antrostomy of inferior nasal meatus approach. Control group (40 cases) was treated through antrostomy of inferior nasal meatus approach. On the basis of the review, the local state of the nasal endoscope and the CT examination of the sinus and the nasal sinuses, the patients were evaluated comprehensively. Results The recovery rate in experiment group was significantly higher than that in control group:97.5%(39/40) vs. 77.5% (31/40), and the complication rate in experiment group was significantly lower than that in control group:10.0%(4/40) vs. 35.0%(14/40). And there were statistical differences ( P<0.01). Conclusions The approach of windowing middle meatus maxillary sinus associated with antrostomy of inferior nasal meatus in the treatment of maxillary sinus cyst in nasal endoscope has wide field and no dead ends. Moreover, the lesions can be cleared completely. The procedure can reduce the recurrence. The complication rate is lower than the antrostomy of inferior nasal meatus approach.
