Department of Ophthalmology, 58934Korea University College of Medicine, Guro Hospital, Seoul, South Korea.

The purpose of this study was to investigate whether the use of hyaluronic acid/collagen resorbable gel (Regenwel) has an inhibitory effect on rhinostomy obstruction during endoscopic dacryocystorhinostomy (Endo DCR). A total of 298 patients diagnosed with unilateral primary acquired nasolacrimal duct obstruction from May 2017 to June 2021 who underwent Endo DCR were enrolled.

'Stenting the Lacrimal System in Modified Denker's for Mucormycosis: Really Needed!'-A Longitudinal Study.

J Maxillofac Oral Surg 2022 Jun 21;21(2):739-742. Epub 2022 Feb 21.

Dept of ENT and Head and Neck Surgery, Baroda Medical College, S.S.G. Hospital, M.S. University, Vadodara, Gujarat India.

Introduction: Recent advances in endoscopic paraphernalia have brought the once intricate anterior lateral wall of maxilla, within reach of the endoscopic surgeon. Endoscopic modified Denker's approach provides another route to reach the indiscernible sites of maxillary & other paranasal sinuses along with PPF (pterygo-palatine fossa)/ITF (infra-temporal fossa) region. This approach has been widely used Pan-India during the Post-Covid Mucormycosis Epidemic, in our country. Read More

Antineutrophil Cytoplasmic Antibody-Associated Vasculitis With Immunoglobulin G4 Involvement in Lacrimal Sac Squamous Cell Carcinoma.

Ophthalmic Plast Reconstr Surg 2022 May 13. Epub 2022 May 13.

Department of Ophthalmology and Visual Neurosciences.

Lacrimal sac squamous cell carcinoma is a rare but life-threatening disease that is often a delayed diagnosis secondary to difficulty in differentiating from other causes of dacrocystitis and acquired nasolacrimal duct obstruction. Chronic inflammation, including that of an underlying autoimmune disease, prior instrumentation, and poor wound healing, may be risk factors in the development to lacrimal sac squamous cell carcinoma. The authors present the first case of lacrimal sac squamous cell carcinoma associated with antineutrophil cytoplasmic antibody-associated vasculitis and immunoglobulin G4 positivity. Read More

Flap suturing endonasal dacryocystorhinostomy assisted by ultrasonic bone aspirator.

Acta Otolaryngol 2022 Mar-Apr;142(3-4):316-322. Epub 2022 Apr 5.

Department of Ophthalmology, University of Toyama, Toyama, Japan.

Background: In the external dacryocystorhinostomy (DCR), a sutured anastomosis technique performed between the nasal mucosal and lacrimal sac flaps reported by Dupuy-Dutemps and Bourguet was the gold standard and was believed to lead to the success of the surgery. However, because of the small working space, a flap suturing technique has not been completely established in endonasal DCR (END-DCR).

Objectives: The effect of the modified flap suture anastomosis technique using a Sonopet ultrasonic bone aspirator was retrospectively compared to that using a diamond burr in patients with nasolacrimal duct obstruction. Read More
