Clinical outcome of endonasal endoscopic prelacrimal approach in managing different maxillary pathologies

The aim of the study was to evaluate the treatment outcomes of endoscopic prelacrimal recess approaches (EPLAs) in managing different sinus pathologies, analyzing associated adverse events and post-treatment quality-of-life.

We enrolled 21 consecutive patients (22 lesions) who received endoscopic sinus surgical procedures with EPLAs in two tertiary medical institutes between 2015 and 2018. Quality-of-life and self-rated symptom severity data were collected using the 22-item Sino-Nasal Outcomes Test (SNOT-22) and 10-point visual analog scales (VAS), respectively.

A total of 21 patients (mean age (standard deviation) 51.7 (14.5) years; 16(76.2%) male) were followed up for 12.7 months. The most common symptoms were nasal discharge and nasal airway obstructions. Nine lesions (40.9%) were sinonasal papilloma's, seven lesions were other types of neoplasms (31.8%; five benign and two malignant), two were trauma-related (9.1%), and four inflammatory diseases (18.2%). Patients with non-papilloma lesions had higher presurgical SNOT-22 than those with papillomas (P-value = 0.021). After EPLAs, non-papilloma patients had significant improvements in SNOT-22 and VAS (P-values = 0.012 and 0.012, respectively), while those with papillomas had only marginally significant improvements in VAS (P-value = 0.061). The most common adverse events was temporary cheek/tooth numbness (n = 11), and patients with sinonasal papillomas were more likely to have post-treatment complications than those with other disease entities.

EPLAs were found to effectively manage various sinus diseases. Short-term life-quality improvements were promising. Future large-scale studies with longer follow-up periods are recommended.
