The Role of Lacrimal Intubation in the Management of Facial Trauma and Tumor Resection

Canalicular laceration repair using a novel bicanalicular silicone stent versus traditional bicanalicular stent with nasal fixation

PURPOSE

To compare the clinical effects of two types of lacrimal stents in the repair of canalicular lacerations.

METHODS

A retrospective analysis was conducted on patients with canalicular lacerations between January 2017 and December 2022. The canalicular reconstruction was performed using either the Runshi-RS bicanalicular silicone stent or the traditional bicanalicular silicone stent with nasal fixation, under a surgical microscope. The stent was placed for 3 months, and patients were followed up for more than 3 months after extubation. The anatomical and functional success rates were compared between the two groups. Anatomical success was assessed through diagnostic probing and irrigation of lacrimal passage, while functional success was determined by the patient's subjective symptoms of epiphora.

RESULTS

The study included 315 patients (315 eyes) undergoing canalicular laceration repair. The Runshi-RS stent was utilized in 147 patients (46.7%), while the traditional stent with nasal fixation was employed in 168 patients (53.3%). The anatomical success rates (99.3% vs 98.8%, P = 0.642) and functional success rates (87.2% vs 88.1%, P = 0.926) were similar between the RS group and the traditional stent group. Postoperative complications were fewer (4.1% vs 10.1%, P = 0.04) and the operation time was shorter (67.1 ± 35.3 min vs 86.1 ± 43.4 min, P < 0.001) in the RS group.

CONCLUSION

The Runshi-RS tube demonstrates favorable surgical outcomes for the repair of canalicular lacerations. Compared to the traditional stent with nasal fixation, the RS stent allows for shorter operation times and fewer postoperative complications in the repair of canalicular lacerations.

[Lacrimal canalicular transposition for lower canaliculus repair: About four cases]

The main function of the eyelids is to support and protect the globe. The lower eyelid and medial canthus are often the location of malignant tumors that can be locally aggressive and require disfiguring surgeries. Chronic epiphora often appears in cases of inadequate reconstruction in this location and can require secondary procedures. We report four cases of medial canthus repair after tumor removal with loss of the inferior canaliculus. The ipsilateral superior canaliculus was removed before being transposed into the lower eyelid. This simple method allows for complete canalicular reconstruction. It obviates the need for artificial material and its potential associated complications. It has the advantage of a one-step eyelid and canalicular reconstruction and prevents epiphora after tumor resection.

Holding back the tears: is there a role for marsupialisation?

Objective

Medial eyelid tumours may result in the loss of the proximal lacrimal system during staged excision and delayed reconstruction, to achieve tumour margin clearance. The remnant canaliculus was marsupialised during reconstruction. The aim was to understand how many patients experienced symptomatic epiphora as a consequence of this.

Methods and analysis

A retrospective study including patients over a 15-year period with medial eyelid tumours, where the proximal lacrimal system was sacrificed to achieve tumour margin clearance. Included were all who had marsupialisation of the remnant distal stump as part of their delayed reconstruction. All who had pre-existing epiphora were excluded. The primary objective was the rate of epiphora following the procedure. A systematic literature review of postoperative epiphora occurring in patients with lid tumours requiring lacrimal system injury/sacrifice during tumour excision.

Results

There were 22 eyes (22 patients). All were basal cell carcinomas except for 1 (4.5%) tarsal conjunctival squamous cell carcinoma. All cases involved the lower lid. There were two (9.1%) patients who developed epiphora. One patient underwent a superior three-snip punctoplasty, botulinum toxin to the lacrimal gland and conjunctivodacryocystorhinostomy with Lester Jones tube insertion. The other patient was not overly troubled and did not require further treatment. The literature review showed the median postoperative rate of epiphora in these patients was 12.5% (range 0%–100%).

Conclusion

Marsupialisation of the remnant canaliculus during delayed reconstruction is a straightforward and effective surgical option, which may help prevent postreconstruction epiphora when the proximal lacrimal system is sacrificed for tumour margin clearance.

Prophylactic Intraoperative Nasolacrimal Duct Intubation in Surgical Treatment of Facial Fractures—Is There a Role?

Nasolacrimal duct (NLD) damage is associated in the majority of type II and III naso-orbito-ethmoid (NOE) fractures. ¹ Our study aims to investigate the efficacy and safety of prophylactic NLD intubation in the setting of facial fractures, by comparing incidence of postoperative epiphora and wound infection. A retrospective matched control study was conducted on all patients with surgically treated facial fractures from 2008 to 2013 ( n  = 280) (IRB ref number: DSRB 2013/01198). Patients with the following fracture types were included: NOE ( n  = 16), frontal sinus ( n  = 2), Le Fort II/III ( n  = 8), and > 1 type ( n  = 48). All patients in this study were included with the intention to treat. The study group comprised patients who were intubated, while the control group patients were not intubated. Each group had 37 patients matched for age, gender, fracture type, and injury type. A single oculoplastic surgeon skilled in lacrimal surgery performed the procedure for all intubated patients. Patients with more severe and complex facial fractures were intubated with bicanalicular Crawford stents. Postoperative epiphora and infective complications (both facial wound and dacryocystitis) were assessed at 1, 3, 6, and 12 months. There was no significant difference in incidence of either postoperative epiphora ( p  = 0.152) or wound infection ( p  = 0.556) comparing both groups. Reduced incidence of postoperative epiphora in the study group is statistically not significant and does not support the need for prophylactic intubation. If radiographic evidence of NLD disruption or regurgitation seen on syringing on the NLD intraoperatively is present, intubation is safe and efficacious only if performed by an expert.

Eiology and prognosis of canalicular laceration repair using canalicular anastomosis combined with bicanalicular stent intubation

BACKGROUND

To evaluate the etiology of lacrimal canalicular laceration and explore the possible risk factors influencing prognosis.

METHODS

The data of 142 patients (142 eyes) with lacrimal canalicular lacerations who were surgically treated using canalicular anastomosis combined with bicanalicular stent intubation between March 2017 and March 2018 were reviewed. The analyzed data contained demographic information, types of trauma, injury locations, associated additional ocular injuries, and surgical outcomes at follow-up. The main outcome measures were anatomic success rate, functional success rate, and complications of surgery.

RESULTS

The mean patient age was 42.07 years (ranging from 1 to 75 years). Among the 142 patients, 112 (78.87%) were males. Upper and lower canalicular lacerations were found in 14 (9.86%) and 112 (78.87%) patients, respectively. Meanwhile, both upper and lower canalicular lacerations were found in 16 (11.27%) patients. Electric bike accidents comprised the leading cause of injury, accounting for 76 (53.52%) cases. There were 100 (70.42%) patients who had lid lacerations without tarsal plate fracture and 42 (29.58%) patients who had lid lacerations with tarsal plate fractures. The anatomic success rate was 98.59% and the functional success rate was 83.8%. The functional reconstruction failure rates were higher in patients with indirect injuries, lid lacerations with tarsal plate fractures, and those with punctum splitting (P < 0.05). Surgical complications were detected in the form of lacrimal punctum ectropion in 3 (2.11%) patients, punctum splitting in 2 (1.41%) patients, and stent extrusion and loss in 2 (1.41%) patients.

CONCLUSIONS

Electric bike accidents have become the leading cause of injury instead of motor vehicle accidents because of the changes in the lifestyles of people. Indirect injuries, lid lacerations with tarsal plate fractures, and those with punctum splitting were significantly more likely to lead to poor prognosis, as confirmed by the lower functional success rate of surgery.

Epiphora after nasolacrimal duct fracture in patients with midfacial trauma: A retrospective study

The aim of this study was to identify the factors related to occurrence of epiphora or requirement of dacryocystorhinostomy (DCR) in patients with midfacial trauma.We performed a retrospective analysis of the medical records of 1038 patients with midfacial trauma from January 2005 to December 2015. Fifty-one patients (55 cases) diagnosed with nasolacrimal duct (NLD) fracture using facial bone computed tomography were enrolled. Correlation analysis was performed of patient- and injury-related factors, including age, sex, facial trauma etiology, accompanying injury, type and level of the NLD fracture, and time from injury to initial surgery, with the occurrence of epiphora and requirement for DCR.Epiphora occurred in 14.5% and DCR was performed in 5.5% of the patients with NLD fracture. The correlation analysis revealed no significant relationship among the factors with the occurrence of epiphora and requirement for DCR.In patients with midfacial trauma and NLD fracture, epiphora occurred in 14.5% and endoscopic DCR was performed due to persistent epiphora in 5.5% and its result was all successful.

Stitch guide technique for bicanalicular nasal intubation in single canalicular laceration reconstruction

Various surgical techniques for canalicular laceration reconstruction have been described in previous study. But there are still two difficult points which may take time in the operation even with the assistance of magnification. We present a simple and effective way to achieve the bicanalicular nasal intubation for the single canalicular laceration. From Jan 2005 to Dec 2015, 20 patients (21 eyes) with upper or lower canalicular laceration were treated with the Crawford lacrimal intubation set by this stitch guide method. We used the eye pigtail probe and the steel probe of the intubation set to dispose a 4-0 Nylon suture as a guide to pull down the silicone tube to the nostril. The functional and anatomic success rates in the 20 eyes are 90% (18/20) and 85% (17/20) respectively. The average time for bicanalicular nasal intubation by this method is 6.87 ± 1.83 min. The result of stitch guide technique to achieve bicanalicular nasal intubation in single canalicular laceration reconstruction is almost the same as the traditional method. Our anatomic and functional success rates are 85% and 90% respectively which are comparable to the previous studies. But this new method takes less time to complete the intubation with little variation. The magnification with microscopy could be omitted and no new instrument is needed. The stitch guide technique for bicanalicular nasal intubation with Crawford intubation system is a reliable and easy way to perform in single canalicular laceration reconstruction.

A new method for locating the proximal lacerated bicanalicular ends in Chinese preschoolers and long-term outcomes after surgical repair

This report is to explore the long-term outcomes of surgical repair of bicanalicular lacerations in Chinese preschool patients. In this report, 12 patients with bicanalicular lacerations were studied between September 2010 and September 2015. The distance from the punctum to the distal canalicular lacerated end was recorded before surgery to classify different types of trauma. All patients underwent surgical repair of the lacerated canaliculi by 1 surgeon within 48 hours after the trauma occurred. After treatment, the lesions were divided into 3 types according to the distance from the punctum to the distal lacerated canalicular end as follows: lateral, medial, and the central. Based on this classification, each lacerated canaliculus was successfully repaired. Nearly half of the lesions (46%) were lateral, 42% were central, and 12% were medial. The average time for locating the proximal lacerated end of the canaliculus was 3.33 ± 1.52 minutes (range, 1.0-7.0 minutes). The follow-up time ranged from 6.0 months to 4.5 year (median, 25 months). Our study showed that 96% (23) of the canaliculi were completely patent. One lateral lesion presented with residual outdoor epiphora in cold weather secondary to left lower canalicular stenosis. All 12 patients had excellent cosmetic results. Our study displayed a surgical management based on the 3 types of lesions helped to find the proximal lacerated end of the canaliculus, and provided excellent long-term outcomes of drainage function.

Upper Eyelid Reconstruction

Reconstruction of the upper eyelid is complicated because the eyelid must retain mobility, flexibility, function, and a suitable mucosal surface over the delicate cornea. Defects of the upper eyelid may be due to congenital defects or traumatic injury or follow oncologic resection. This article focuses on reconstruction due to loss of tissue. Multiple surgeries may be needed to reach the desired results, addressing loss of tissue and then loss of function. Each defect is unique and the laxity and availability of surrounding tissue vary. Knowing the most common techniques for repair assists surgeons in the multifaceted planning that takes place.

Surgical management of traumatic nasolacrimal duct obstruction

PURPOSE

To evaluate etiologies, demographics, and surgical outcomes in cases of traumatic nasolacrimal duct obstruction (NLDO).

METHODS

Charts of 35 patients with the diagnosis of traumatic NLDO were reviewed retrospectively. Patient demographics, type of trauma, previous lacrimal surgery history, surgical treatment, follow-up time, and anatomical and functional outcomes were evaluated.

RESULTS

Forty eyes of 35 patients were included in this study over 12 years. Twenty-four patients were male (68.5%) and the mean age of the patients was 31.52 ± 14.58 years (range 9-68). The most common etiology was motor vehicle accidents (52.5%), followed by high velocity blunt injury (27.5%), accidental fall (7.5%), occupational trauma (5%), iatrogenic surgical trauma (5%), and animal bite (2.5%). A total of 21 eyes (52.5%) were treated with external dacryocystorhinostomy (DCR), 30% with conjunctival DCR, 15% with endoscopic DCR, and 2.5% with diode laser-assisted DCR. Mean follow-up time was 23.02 ± 13.53 months. Functional and anatomical success was recorded in 37 out of 40 eyes (92.5%).

CONCLUSIONS

Naso-orbitoethmoidal fracture is the main etiology of traumatic NLDO. The majority of the injuries occurred in male participants from motor vehicle accidents and high-velocity blunt injury. Dacryocystorhinostomy provides anatomical and functional success in 92.5% of cases of traumatic NLDO.

Intraoperative lacrimal intubation to prevent epiphora as a result of injury to the nasolacrimal system after fracture of the naso-orbitoethmoid complex

Treatment of fracture of the naso-orbitoethmoid (NOE) complex is difficult. There are not only aesthetic issues but also functional consequences related to the lacrimal system. Because prophylactic lacrimal intubation for such fractures remains controversial, we have assessed the effectiveness of intraoperative lacrimal intubation to prevent epiphora as a result of such injuries. Thirteen patients diagnosed with craniomaxillofacial fractures including fractures of the NOE complex were included in the study; 10 had unilateral fractures and 3 bilateral. Computed tomography (CT) showed all patients had displaced fragments that had the potential to damage the lacrimal duct. In 7 patients the fractures included the canthal region and in 6 they did not. All patients were treated by open reduction and internal fixation under general anaesthesia, followed by intraoperative lacrimal intubation unilaterally or bilaterally as required. Lacrimal intubation with a silicone tube was successful in all 13 patients (16 sides). The tube was removed 2-9 months (mean 3.8) postoperatively and no subsequent epiphora were seen during follow-up (mean (3-29 months) 11.3 months). Lacrimal intubation for at least 2 months may prevent epiphora caused by injury to the nasolacrimal system after fractures of the NOE complex.

The contemporary management of midface and craniofacial trauma

The successful management of midface and craniofacial trauma requires a thorough understanding of the anatomy and functional demands of this complex region. To achieve optimal outcomes, it is necessary that these injuries are accurately diagnosed and managed in a multi-disciplinary environment at the appropriate time. This review article discusses an overview of these injuries and highlights some of the key principles of management.

Reconstructive options for the medial canthus and eyelids following tumor excision

General principles provide the framework for eyelid and periorbital reconstruction following tumor excision. Eyelid tumors involving the medial canthus region and/or lacrimal system add to the complexity of reconstructive planning. The nature of the tumor, patient and tissue factors, and surgeon preference guide repair design choices. Reconstructive considerations and options following medial canthal tumor resection are described.
