“…The most common causes of iatrogenic nasolacrimal canal damage during orthognathic surgery include high Le Fort I osteotomies, inferior turbinectomy, instrumentation, and the placement of osteosynthesis screws. It usually occurs during the osteotomy or placement of the osteosynthesis screws ( 7 ). This is the first study in which the relationship between fixation screws and drills placed during osteosynthesis and the nasolacrimal canal was evaluated.…”

“…study, partial turbinectomy and septoplasty were performed to remove edema and the septal deviation causing NLDO ( 11 ). Ten of the 15 reported cases were treated with NLDO dacryocystorhinostomy ( 7 ). In previous studies, NLDO has often been associated with high Le Fort I osteotomies and inferior turbinectomy.…”

“…Özcan et al . investigated the prevalence of nasolacrimal canal obstruction and epiphora following maxillary orthognathic surgery ( 7 ). In the examination of the postoperative records of 83 patients, symptoms of nasolacrimal duct obstruction were reported in 3 patients, which lasted an average of 32.7 days.…”

“…Lacrimal system injury is a rare complication after facial trauma, craniomaxillofacial surgery, rhinoplasty, nasal osteotomy, and Caldwell-Luc procedures accompanied by a nasal antrostomy. The anterior wall of the lacrimal sac and the distal aperture of the nasolacrimal duct is particularly vulnerable to inadvertent injury during craniofacial surgery ( 7 ). Nasolacrimal duct injury is another complication that occurs rarely during the Le Fort osteotomy.…”

“…Rarely, nasolacrimal system disruption following surgery results in a permanent obstruction, causing persistent epiphora or recurrent dacryocystitis. The Le Fort I surgery procedures that involve the superior repositioning of the maxilla, inferior turbinectomy, the insertion of osteosynthesis screws, or high Le Fort I osteotomy techniques are more likely to result in nasolacrimal duct injury ( 7 ). There are limited studies on the relationship between nasolacrimal canal injuries and Le Fort I osteotomies.…”

Background Although Le Fort I surgeries are safe and successful procedures; nasolacrimal duct injuries may be observed due to these surgeries. The study aimed to investigate the prevalence of nasolacrimal duct injury in Le Fort I osteotomy patients. Material and Methods The authors conducted a retrospective cohort study consisting of patients who underwent Le Fort I osteotomies between 2017 and 2021 in the Erciyes University Faculty of Dentistry. The primary predictor variables were the distance of the nasolacrimal canal to the outer cortex of the maxilla and the nasal floor, as well as the superior-inferior level of the superiorly positioned screw inserted in the maxilla aperture region relative to the nasolacrimal canal. The outcome variable was the presence of a nasolacrimal duct injury. Mann Whitney U test was used for quantitative variables between the two groups. A Pearson chi-squared analysis was used to compare categorical data. A p-value <0.05 was considered statistically significant. Results A total of 290 nasolacrimal canals were evaluated in 145 patients, 87 females, and 58 males. The mean age was 23.47± 6.67. There was a statistically significant relationship between screw level and nasolacrimal canal perforation ( p <0,001). The distance between the most anterior border of the nasolacrimal canal and the outer cortical of the maxilla was significantly less in the perforation group ( p <0,001). The fixation screw was significantly closer to the nasolacrimal canal in the perforation group ( p <0,001). Conclusions In Le Fort I surgery, nasolacrimal duct injury may occur during screw fixation to the aperture region. Superiorly positioned fixation screws in the aperture region may damage the nasolacrimal canal. In patients where the nasolacrimal canal is close to the outer cortex, care should be taken when applying the fixation screws to the aperture region to avoid damaging the canal. Key words: Le Fort 1 osteotomy, nasolacrimal canal injury, fixation.
