Abstract

Pathologies of the lacrimal drainage system range from benign to malignant lesions. However, independently of the etiological origin, the most common presenting symptom is represented by epiphora due to the dysfunction of the lacrimal system. Different diagnostic tools are now available, but for the most the first diagnostic approach is characterized by an ophthalmological visit, associated with nasal endoscopy, usually performed by an otolaryngologist. Frequently the diagnostic work-up is completed with a radiological exam (e.g. maxilla-facial CT or dacryocystography), whose role is still to be determined. Once a diagnosis has been made, different treatments are available in relation to the type of the disease, and commonly need close cooperation between an ENT and ophthalmic surgeon given the close anatomical structures involved. Taking into account all these aspects, the aim of this review is to highlight how a multidisciplinary approach to lacrimal pathologies is mandatory from diagnosis to treatment in order to offer the best clinical approach.

Introduction

The lacrimal drainage system (LDS) is a complex apparatus that is responsible for flow of tears from the eye (medial cantus) to the nasal cavity (inferior meatus). Any pathology of this system usually appears as watery eye, also known as epiphora, which is a common clinical sign that can be caused by different factors that are mainly classified as reduced outflow (e.g. lacrimal obstruction, eyelid malposition), hypersecretion of tears and reflex tearing 1. Among all these, lacrimal obstruction is the most common cause and can be distinguished in congenital, if it appears before the first year of life, and acquired forms 2,3. Additionally, if considered the site of the obstruction, it can also be divided in proximal (punctum, superior, inferior and common canaliculus) and distal (or post-canalicular) lacrimal obstruction, which is the most common 2. The latter form is most commonly encountered in middle-aged female patients in whom different local and systemic pathologies may cause lacrimal obstruction 1,4-12.

Regardless of its etiology, epiphora has substantial impact on the quality of life, thus making its correct approach fundamental 13,14. In past years, lacrimal pathologies were mainly managed by an ophthalmologist due to the clinical presentation and the treatments that were available. Nowadays, with the advent of rigid endoscopes, the approach of these types of pathologies has radically changed, leading to cooperation with an otolaryngologist (ENT). Moreover, thanks to this technological implementation, not only has it permitted executing standard dacryocystorhinostomy through an endonasal endoscopic approach (END-DCR), but it has also gained a major role pre-operatively: in fact, endoscopic analyses of the nasal fossa permits direct and optimal identification of surgical landmarks and anatomical variations that can affect the surgery (e.g. nasal septum deviation, paradoxical middle turbinate). Additionally, endoscopic instrumentation can be used post-operatively, thanks to the importance of direct visualization of the healing process. Surprisingly, it has been reported that nasal examination is not usually performed by most ophthalmologists, with potential consequences on treatment outcomes 15.

In the past, several authors have tried to identify the best clinical practice for lacrimal diseases, but no one has taken into account the role of multidisciplinary consultation between an ophthalmologist and otorhinolaryngologist in the management of lacrimal pathologies. The aim of this review is to analyze the role of a multidisciplinary approach to lacrimal pathologies, from the diagnosis to treatment.

Diagnosis

The pathologies that may affect the lacrimal pathway are numerous and differential diagnosis between them can be challenging 16. The finer aspects of a precise assessment of the lacrimal pathology is beyond the scope of this paper. However, most of the literature agrees that in-office ophthalmologic examination is the first diagnostic step that should be taken in case of suspicion of lacrimal pathologies (Fig. 1) 17. In fact, clinical examination provides an assessment of lacrimal structures, eyelids, punctal position, meibomian gland, lacrimal gland and possible pathology of the ocular bulb, providing an initial differential diagnosis of the primary lacrimal pathway pathologies to secondary ones and its potential functional/obstructive nature 1. Such an initial diagnostic step is a non-invasive, easy and low-cost way to establish an initial diagnosis, and if the result of this examination confirms a pathology of the eyelid, lacrimal gland, ocular bulb or meibomian gland, an otolaryngologist is not always required 16. On the contrary, clinical examination of the nasal cavities by an otolaryngologist remains of major interest in case of both functional and obstructive lacrimal pathway pathologies 15. In fact, even if in some lacrimal pathologies, like functional diseases, the available treatments are primarily performed by an ophthalmologist, the role of an otolaryngologist remain fundamental since he can provide an endoscopic assessment of the nasal fossa, excluding any form of influencing factors 15. Similarly, in case of lacrimal obstructive pathologies, endoscopic assessment of the nose is important for diagnostic purposes (e.g. presence of neoplastic mass), direct evaluation of the endonasal space that can influence the decision of the treatment to be performed, and for identification of the potential surgical influencing factors such as the nasal septum deviation, nasal mucosa pathologies, paradoxal middle turbinate, and abnormalities of the nasal fossa 8.

As a result, to establish the best diagnosis for each patient affected with a pathology of the lacrimal drainage system, accurate and specific work-up is fundamental and needs to be done through multidisciplinary consultation between an ophthalmologist and otorhinolaryngologist.

In addition to this, different radiological studies are now available with the aim of precise identification of the lacrimal disease etiology: in particular, this diagnostic step is fundamental in case of neoplastic disease, since the clinical presentation of the tumor can be non-specific, such as medial cantus tender mass, bloody tears and epiphora, painless and with no endoscopic endonasal signs 11. Nevertheless, its application in non-oncologic lacrimal pathologies is controversial 17. A recent survey has demonstrated a relative lack of interest for lacrimal imaging among ophthalmic plastic surgeons 18. However, there are times in which a specific diagnosis remains unclear and imaging of the lacrimal system may be used to help evaluate its function and anatomy. Specifically, Lefebvre et al. suggested that radiologic tools must be used in case of neoplastic suspicion and should be applied in case of re-operation or when there is suspicion of complicated anatomy 17. The adjunctive information that can be obtained through radiological exams are important for both ophthalmic and ENT surgeons since they can provide the exact position of the obstruction and presence of anatomical malformation that can be missed with clinical/endoscopic exam 16.

At present, different imaging techniques are available (e.g. maxillo-facial CT, dacryocystography, MRI, dacryoscintigraphy, single-photon emission computed tomography); however, no unanimous consensus on the gold standard radiologic tool has been achieved 17.

Treatment

Given the large range of lacrimal pathologies described, analysis of their treatment needs to be divided into proximal and distal lacrimal pathologies, related to the site of the disease. A complete assessment of the possible treatments available for lacrimal pathologies is beyond the scope of this manuscript, although generally speaking collaboration between an ENT surgeon and ophthalmologist is mandatory in distal lacrimal obstructions, whereas in proximal pathologies it can be recommended in relation to the type of the disease. Conversely, in case of a pump defect or functional disease, multidisciplinary treatment is not generally required since these are primary ophthalmologic pathologies.

Proximal lacrimal obstructions

Lacrimal pathologies proximal to the valve of Rosenmuller are mainly divided into punctum (e.g. punctual stenosis, punctual membrane, cicatrizing disease) and canaliculus disease (e.g. stenosis, scarring and foreign bodies) 1. If the former can be generally treated with punctoplasty, i.e. a surgical procedure with the aim of widening the tight punctum, canaliculus disease can be approached conservatively or surgically. In particular, a probing stenting of the proximal lacrimal pathway can be done and, if not successful, conjunctivodacryocystorhinostomy can be perfomed. The latter is a surgical procedure that creates a neo-passage from the conjunctiva to the middle meatus of the nose 19.

All the treatments described for proximal obstruction of the lacrimal pathway are generally performed by an ophthalmic plastic surgeon and the collaboration with an ENT is not always mandatory. However, conjunctivodacryocystorhinostomy is an approach in which the otolaryngologist can be helpful, since endoscopic assessment of the nasal cavity allows easy visualization of the correct position of the lacrimal tube and implementation of nasal co-interventions during the approach 20.

Nevertheless, these rules concern benign lesions since malignant ones require close collaboration with the ENT surgeon: in fact, even if a primary malignancy of the proximal lacrimal tract is rare, stenosis of the lacrimal pathway secondary to extrinsic compression due to sino-nasal, orbital and cutaneous malignancy can occur and needs to be treated in a multidisciplinary manner in order to eradicate the tumor and re-establish functional eye to nose tear flow.

Distal lacrimal obstructions

Distal acquired lacrimal obstructions present different treatments related to the etiology and age of the patient. In general, the most common location of the stenosis of this form is the nasolacrimal duct (NLD) 9.

If the congenital form is taken into account, lacrimal duct closure is usually caused by a mucosal membrane at the level of Hasner’s valve or by a bony constriction of the NLD 21,22. Congenital NLD obstruction is commonly managed conservatively: in particular, most patients experience spontaneous resolution of the pathology by the end of the first year, thanks to a bony development that allows an enlargement of the lacrimal duct 23. Some clinicians usually prescribe a non-invasive procedure, Crigler’s lacrimal sac compression, with which a simple inward lacrimal compression of the lacrimal sac enhances hydrostatic pressure within the system in order to overcome the common membranous obstruction 24. As an alternative, a stenting-probing of the lacrimal system can be performed 25. All these different approaches, commonly performed by an ophthalmic plastic surgeon, provide a success rate of up to 90%. In the event of challenging cases, endoscopic endonasal dacryocystorhinostomy (END-DCR) is an established procedure to address unmanageable congenital obstructions, making a multidisciplinary approach with an ENT a possibility in case of this refractive form 26.

Considering the adult form of distal lacrimal obstruction (DALO), the most common pathologies can be distinguished as oncologic and non-oncologic (primary and secondary) forms. Primary acquired and secondary, non-oncologic, diseases have several treatments available, both surgical and non-surgical, that can be performed by different clinicians. Among all, a recent review has pointed out that external dacryocystorhinostomy (EXT-DCR) and END-DCR present higher functional success rates compared to other techniques, and should be considered as treatments of choice 27. In these cases, the collaboration between ophthalmic plastic and ENT surgeons is necessary because, if a END-DCR is performed, management of the proximal lacrimal pathway is required and needs the presence of the ophthalmologist (Fig. 2); conversely, if an EXT-DCR is performed, endoscopic direct visualization of the surgical landmark and potential anatomic variation can be helpful in order to decrease potential influencing factors of the surgical outcome 15.

If a secondary re-stenosis of the neo-rhinostomy occurs, END-DCR seem to be the treatment of choice since it provides direct visualization of intranasal abnormalities which cause surgical failure, with no superiority demonstrated over EXT-DCR 28. In addition to this, a new endoscopic approach has been proposed, based on endonasal balloon dilatation of the stenotic neorhinostomy, with encouraging data 29,30 (Fig. 3). In general, it seems that both primary and secondary approaches to non-oncologic DALO would benefit from a multidisciplinary approach 28.

Malignancies of the distal lacrimal pathway have a wide range of histologies, with an epithelial origin the most common form. In general, treatment is based on complete and wide surgical resection, which commonly requires excision of adjacent structures. As a result, considering the necessary reconstruction of the lacrimal pathway and the potential combined approach to the orbital area, a multidisciplinary approach is indispensable 11.

Post-surgical management and follow-up

Following proper treatment, several post-surgical medical therapies are available, and, seem particularly useful in case of non-oncologic DALO. However, with the available data, the actual influence of adjunctive medical therapies is difficult to demonstrate 31, and endoscopic visualization of the healing process associated with nasal medication and lacrimal pathway irrigation remain the prevalent post-surgical management tools that can positively influence the surgical outcome of all forms of DALO. In fact, the periodic washing procedure of the lacrimal pathway and endoscopic treatment of the neo-rhinostomy can allow for better healing, and thus leading to better surgical outcomes 15. As a result, post-surgical multidisciplinary approach remains of vital importance in long-term follow-up: in fact, on one hand the ophthalmologist can perform clinical evaluation of the lacrimal pathway, and on the other the ENT can endoscopically evaluate the neo-rhinostomy and provide additional information about the healing process (Fig. 4) 15.

At present, no definitive follow-up timing has been established, but it seems reasonable that this should be at least 6 months for non-oncologic DALO 27, up to 18 months for failure surgeries 32, and at least 5 years for oncologic DALO 11.

Conclusions

The correct approach to lacrimal drainage system pathologies can be challenging due to the location of this apparatus and the different diseases that can influence physiological lacrimal flow. Considering both its diagnosis and treatment, a multidisciplinary approach with an ophtalmic plastic and ENT surgeons is frequently required, especially in distal forms, since such cooperation offers the best clinical approach available. In fact, even if most treatments of this apparatus are generally performed by an ophtalmologist, the additional information and surgical approach (END-DCR) that an ENT clinician provides can radically influence the decision making process and final success rate, making this cooperation of vital importance. Recommendations for multidisciplinary approach have been resumed in Table I.
