Endoscopic endonasal retrieval of a nasolacrimal duct stone via the valve of Hasner in the inferior meatus

A case report of chronic dacryocystitis caused by nasal stones

BACKGROUND

This paper reports a case of chronic dacryocystitis due to nasal stones.

CASE PRESENTATION

An 84-year-old male patient was admitted to the hospital with chronic dacryocystitis of the right eye due to tearing and purulent discharge from the right eye for more than 1 month. Antibiotic treatments such as gatifloxacin eye drops were given at other hospitals but did not relieve the symptoms. A computed tomography(CT) scan of the lacrimal duct in our department showed a high-density shadow in the right lacrimal sac area, hypertrophy of the right inferior turbinate, and many nasal calculi in the nasal cavity. The patient was transferred to our otolaryngology department for further treatment, and nasal stones were removed under nasal endoscopy. Three days after surgery, the symptoms affecting the patient's right eye gradually resolved. One month after surgery, the patient underwent a follow-up examination in the ophthalmology clinic; there was no lacrimal purulent discharge from the right eye, and the lacrimal duct could be flushed smoothly.

CONCLUSION

Chronic dacryocystitis is often caused by primary nasolacrimal duct obstruction. Cases of chronic dacryocystitis caused by secondary nasolacrimal duct obstruction due to nasal stones are rare in the clinic. This case can serve as a reference for the clinical diagnosis and treatment of chronic dacryocystitis.

Comparison of Hasner valvulotomy outcomes in pediatric and adult patients: does age matter?

BACKGROUND

Hasner valve incision has been recently introduced as a new treatment for ophthalmic patients with epiphora symptoms. The aim of this study was to examine whether surgical outcomes of Hasner valve incision for inferior nasolacrimal duct obstruction were different between pediatric and adult patients.

METHODS

A total of 53 eyes of 52 patients who underwent Hasner valve incision in the Beijing Tongren Hospital from October 2016 to November 2019 were retrospectively observed. Patients were divided into two groups, including pediatric group (23 eyes of 22 patients, <18 years old) and adult group (30 eyes of 30 patients, ≥18 years old). Success rate of surgery was determined by both subjective measure (complete resolution of epiphora) and objective measure (lacrimal passage irrigation and tear meniscus height). Fisher exact test was conducted.

RESULTS

By conducting Fisher exact test and comparing complete resolution of epiphora (P = 0.627), lacrimal passage irrigation (P = 0.663), measurement of Tear Meniscus Height (P = 0.561), and appearance of complication (P = 0.339), there was no statistically significant difference of surgical outcomes between pediatric and adult patients (P > 0.05).

CONCLUSION

Hasner valve incision was effective for both adult and children with inferior nasolacrimal duct obstruction, with no difference in surgical outcomes between the two groups.

Avoiding dacryocystorhinostomy in cases of epiphora caused by inferior meatus obstruction

AIMS

To determine the role of inferior meatus pathologies as an underdiagnosed cause of epiphora.

METHODS

This study was conducted in the oculoplastic institution of Tel Aviv medical center-a regional referral center. A retrospective review of files of patients presenting to the lacrimal clinic with nasolacrimal duct obstruction between October 2010 and September 2016. Cases in which a pathology of the inferior meatus was identified and treated are presented in this article.

RESULTS

During this time frame, we preformed 186 endoscopic dacryocystorhinostomy surgeries. Out of those, eight patients (4.3%) were diagnosed and treated for pathology causing an obstruction of the inferior meatus. Seven of our patients were females; the mean age was 24 years. A wide range of pathologies were found: cysts, dacryoliths, membranes obstructing the inferior meatus, and concheal obstruction. All patients went through endoscopic treatment targeted at the cause of obstruction. During follow-up (average 35 months) only two patients remained symptomatic and were referred for an endonasal endoscopic dacryocystorhinostomy.

CONCLUSIONS

Inferior meatus obstruction is an underdiagnosed cause of epiphora. Multiple pathologies may co-exist in the same patient. In select cases of NLDO, diagnosis and treatment can be done endoscopically, avoiding the need for dacryocystorhinostomy.
