Congential nasolacrimal duct obstruction: investigating the role of systemic inflammation through novel biomakers.

Objective: Congenital nasolacrimal duct obstruction (CNLDO) is a common lacrimal system anomaly in newborns and infants. We aimed to evaluate the role of inflammation in the pathogenesis of persistent CNLDO and its potential use in diagnosis and follow up, focusing on novel inflammatory biomarkers: Systemic Immune-Inflammation Index (SII), Neutrophil-to-lymphocyte ratio (NLR), Platelet-to-lymphocyte ratio (PLR), Red cell distribution width (RDW), and Mean platelet volume (MPV).

Methods: A retrospective case-control study involving 76 CNLDO patients and 47 age-matched healthy controls was conducted.

Surgical Challenges in the Management of Respiratory Epithelial Cyst Involving the Lacrimal Sac.

Respiratory epithelial cysts are uncommon lesions that can be congenital or acquired cystic malformations. Beyond the respiratory system, the location of the respiratory epithelial cyst has been described in the central nervous system, orbits, and the maxillofacial region. The common etiology is believed to be sequestration or entrapment of the epithelial cells of the paranasal sinus.

Computed Tomography Signs of Sinonasal Inflammation in Patients with Acute Dacryocystitis.

Background: Nasal and paranasal sinus abnormalities may be related to nasolacrimal duct obstructive disease but are strongly debated. Data of acute disease stage are lacking.

Objective: The purpose of this study was to determine if there are correlations between radiologic signs of sinus inflammation and acute dacryocystitis (AD).

Sclerosing Perineurioma of the Orbit.

A 7-week-old boy presented to pediatric ophthalmology with a mass inferior to the medial canthus of the OS that was first noticed on day 3 of life. Crigler massages, warm compresses, and moxifloxacin HCl drops were administered without resolution of symptoms. Probing and irrigation for a presumed dacryocystocele were performed, but the nasolacrimal system was patent, and the mass persisted after the procedure.

Diversity in Lacrimal Pathway Morphology Among Patients with Congenital Nasolacrimal Duct Obstruction.

Purpose: This prospective observational study aimed to explore the diversity in lacrimal pathway morphology among patients with congenital nasolacrimal duct obstruction (CNLDO) by examining dacryocystography (DCG) images.

Patients And Methods: The study included 64 patients who underwent DCG before undergoing general anesthesia probing for unilateral CNLDO. Several parameters were measured from the lateral view of the DCG images: (1) the lacrimal sac (LS) and the nasolacrimal duct (NLD) angle, (2) the angle formed by the superior orbital rim (SOR), LS, and the NLD, (3) LS length, and (4) bony NLD length.

[Anatomical structure and morphometric parameters of the distal segment of the lacrimal drainage system].

The article analyzes the literature data concerning the anatomical structure of the tear ducts with a focus on morphometric studies of individual structures. It is noted that, despite the high information content of cadaveric studies, most of the information to date has been obtained with the use of intravital radiation visualization methods. It is shown that the lacrimal drainage system has age, gender, and racial characteristics.

Nasolacrimal Duct Obstruction Secondary to Eosinophilic Chronic Rhinosinusitis: A Case Report.

A 47-year-old Japanese woman presented with a 1-year history of right-sided epiphora. On initial consultation, the patient had a high right tear meniscus height. CT images revealed bilateral soft tissue opacification in the nasal cavity and maxillary, frontal, and ethmoid sinuses.

Clinical characteristics and cytological changes in mucinous obstruction diagnosed by dacryoendoscopy.

To analyze the clinical characteristics of mucinous obstruction diagnosed by dacryoendoscopy and compared the cytological changes with membranous obstruction using a modified liquid-based thin prep cytology method. A retrospective chart review was conducted on 53 eyes of 51 patients with mucus obstruction based on dacryoendoscopic findings from January 2022 to October 2022. Liquid-based thin-prep cytology was performed by irrigating the inside of the nasolacrimal drainage system with saline during dacryoendoscopy-guided silicone tube intubation.

A transconjunctival surgical technique for dacryocystotomy in dogs with foreign body-induced dacryocystitis.

Purpose: The purpose of this study is to describe a simplified, less invasive dacryocystotomy technique that allows for complete inspection of the canine lacrimal sac and to retrospectively evaluate this surgical technique in a larger series of dogs. The anatomical background of the canine nasolacrimal system is described as a basis for the surgical technique.

Methods: Records of dogs from 2003 to 2023 which were diagnosed with dacryocystitis due to presumed foreign body and underwent surgical exploration and removal of foreign bodies within the lacrimal sac using this technique were reviewed.

[An atypical medial canthal mass: a case of lacrimal sac inverted papilloma with literature review].

Background: Lacrimal sac localization of an Inverted Papilloma is extremely rare and no risk factors are reported in literature.

History: A chemical trauma was followed by a painless, growing mass in the medial canthal area associated with epiphora.

Findings: Rhinoendoscopy, Computed Tomography and Magnetic Resonance showed a well-defined mass in left lacrimal fossa extended to the nasolacrimal duct.

Prelacrimal Recess Approach in Unilateral Maxillary Sinus Lesions: What Is the Impact and Efficacy?

: Chronic sinusitis is a commonly encountered diagnosis for otorhinolaryngologists. The profound negative effect of rhinosinusitis on patients' quality of life is frequently overlooked, and surgical lines of treatment are numerous. The aim of the study was to assess the comparative efficacy of endoscopic middle meatal antrostomy with the endoscopic prelacrimal recess approach, combined with middle meatal antrostomy in the treatment of unilateral chronic maxillary sinus lesion.

Propose: This study aimed to compare the diagnostic accuracy of MR dacryocystography (MRD) and dacryoscintigraphy (DSG) in the diagnosis of acquired epiphora related to NLDO. A total of 15 patients with acquired epiphora and suspected NLDO were included in this study.

Methods: All patients underwent MRD and DSG examinations.

Dacryolithogenesis or Dacryolithiasis-The Story So Far.

The term dacryoliths refers to the concretions found within the lacrimal system. When the term dacryoliths is unspecified, it usually refers to the noninfectious dacryoliths commonly isolated from the lacrimal sac and the nasolacrimal duct. More often, they are diagnosed incidentally during a dacryocystorhinostomy, and the reported incidence among all dacryocystorhinostomy surgeries is 5.
