“…The robotic endoscope guiding system proved to be beneficial for all transnasal steps of the procedure, as two‐handed surgery enabled the surgeon to better manipulate the tissue (Figure 4). 20 In both cases, there were no complications during or after the surgery. In the follow‐up treatment, both patients showed no signs of epiphora.…”

Background: Distal nasolacrimal duct stenosis is usually treated by head and neck surgeons with transnasal endoscopic dacryocystorhinostomy (DCR). The presented clinical study discusses advantages and drawbacks of a robot-assisted endoscope positioning system, which allows for hands-free visualization of the surgical field. Material and Methods: Two patients were treated by surgical DCR. The endoscopic positioning system (Medineering ®) features a mechatronic holding arm with four segments and seven degrees of freedom. It is driven by using a foot pedal. Results: Visualization and instrumentation of the surgical field including the relevant anatomical landmarks were feasible. The endoscope position could be controlled with sufficient precision. The surgeon was able to maintain bimanual instrumentation. Conclusion: The endoscope positioning system allows for two-handed surgery, which facilitates the essential steps of the surgical procedure. If the benefit of the system is sufficient for the use in clinical routine, it has to be evaluated in repeated applications.

“…Nasal endoscopic techniques may bridge this gap. Naso-ocular endoscopic surgery has expanded exponentially in recent years and has been utilized to address 1) optic nerve compression secondary to trauma, cysts, and tumor compression 4 ; 2) lacrimal duct obstruction secondary to chronic lacrimal vasculitis and lacrimal duct tumors 5 ; 3) orbital compartment syndrome and intraorbital hypertension secondary to Graves' ophthalmopathy, intraorbital hemorrhage, and intraorbital in ammatory pseudotumors 6 ; 4) peri-orbital and intra-orbital space-occupying lesions, such as cavernous hemangiomas, neuro brillary sheath tumors, and abnormal bony proliferation; and 5) intra-orbital foreign bodies, including displaced bones from orbital wall fractures, as well as intra-orbital masses 7 .…”

The efficacy of nasal endoscopy for nasal and ocular-related diseases remains largely elusive. We retrospectively analyzed the data of 91 patients (158 eyes) with nasal and ocular-related diseases from Feb 2017 to April 2022 were used to analyze the effects of different operations. We demonstrated that the 13 patients (13 eyes) with traumatic optic neuropathy, nine (69.2%) demonstrated improved visual acuity post-operatively. Of the 65 patients (130 eyes) with thyroid-related ophthalmopathy, 120 eyes (92.3%) have less proptosis post-operatively, whereas 10 eyes showed no changes. One case noted worse visual acuity post-operatively, and 20 eyes noted new-onset diplopia. In eight cases (8 eyes) with retroorbital space-occupying lesions, five patients (62.5%) noted visual acuity and visual field improvements post-operatively. We propose that although nasal endoscopic surgery has some limitations in the orbit, it is a safe, effective, and minimally invasive option for nasal and ocular-related conditions. Close collaboration between ophthalmologists and rhinologists is important.

“…Keywords: dacryocystitis, methylene blue, lacrimal sac, dacryocystectomy MB was synthesised for the first time in 1876 by Heinrich Caro at Badishe Anilin and Sado Fabrik (BASF), being used in textile dyeing [1][2][3], then 15 years later it was the first antiseptic introduced in clinical cure of malaria [1]. MB is now used in a large variety of dyes for multiple purposes and in medicine for a number of therapeutic and diagnostic procedures [2,[4][5][6][7][8][9][10].…”

Methylene blue (MB) has many uses in medicine, being applied as a treatment for infections, malaria, methemoglobinemia, as a dye for diagnosis and for staining of cells, tissues and bacteria. In elderly patients with associated high anaesthetic risk, dacryocystectomy is an alternative to dacryocystorhinostomy. This is an observational clinical study for two cases of chronic dacryocystitis where dacryocystectomy combined with MB (1%) staining of lacrimal sac was performed. Case no.1 - an 81-year old female patient with arterial hypertension, atherosclerosis, pulmonary fibrosis, and lower limb varices complainted of recurrent epiphora, muco-purulent secretions in both eyes, inflammatory oedema of the left perisacular region for the past 6 months. Case no. 2 - a 74-year old female patient with hypothyroidism suffered from chronic epiphora in the left eye with a purple-red oedema of the inferior eyelid and perisacular region. Symptoms reoccurred in the last 10 months despite topical and systemic therapy with antibiotics and anti-inflamatory drugs. Dacryocystectomy was performed under local anaesthesia in both patients. MB (1%) was used to irrigate the lacrimal sac in order to facilitate its localisation, dissection and excision. Results: Case no.1. Ectopic lacrimal sac. Case no.2. Enlarged lacrimal sac (7.5/14 mm). The histopathological examination revealed a trachomatous dacryocystitis, respectively a chronic non-suppurative non-granulomatous dacryocystitis. Their postoperative evolution was without complications, except for a mild epiphora. In conclusion, dacryocystectomy appears to be a less traumatising alternative to dacryocystorhinostomy. The staining of the lacrimal sac with MB (1%) in dacryocystectomy facilitates its identification and dissection, especially when it is ectopic.
