Purpose: To evaluate the efficiency and safety profiles of a technique of simultaneous reconstruction of traumatic lacrimal duct obstruction and medial canthus deformity using micro-anchors.
Methods: A retrospective interventional study was performed from 2018 to 2022 on 26 consecutive patients who presented with medial canthal deformities and traumatic nasolacrimal duct obstruction. All patients underwent medial canthoplasty using micro-anchors combined with dacryocystorhinostomy to address the traumatic nasolacrimal duct obstruction. Preoperative and postoperative measurements of telecanthus, the superior or the inferior displacement of the medial canthal tendon (MCT), surgical technique of MCT fixation, advantages and limitations of using micro-anchors, functional and cosmetic outcomes were recorded and compared.
Results: Satisfactory and symmetrical medial canthal fixation outcomes were achieved in 96% (25/26) patients using the micro-anchors. The surgical technique was easy and offered secure and reliable reattachment of the MCT in long-term. The DCR surgery was anatomically and functionally patent in 92% (24/26) patients. One patient had unsatisfactory medial canthal outcomes where the canthus remained partly lateral, and inferior compared to the uninjured side. The two failures following DCR surgery were secondary to complete cicatricial closure and had persistent epiphora.
Conclusion: The present study noted that micro-anchors can correct the medial canthal deformity and leave more space for the DCR osteotomy simultaneously.

Entomophthoromycosis is a rhinofacial infection. We report a rare presentation of entomophthoromycosis in a 20 year old immunocompetent female presented with left sided nasal block and left medial canthal swelling. Endoscopic evaluation showed a large fibrotic mass in the left nasal cavity closely adherent to the middle turbinate and with intraorbital and intracranial extensions.

Eyelid defects, particularly those affecting the medial canthus, present intricate challenges for reconstructive surgeons due to the complex anatomy and functional significance of the region. This article presents our management of an 87-year-old patient with medial canthal basal cell carcinoma, highlighting the successful management of such defects through a single-stage reconstruction technique involving a skin graft supported by a synthetic dermal matrix (MatriDerm). The utilization of this approach resulted in favorable outcomes, including clear margins on histological examination and stable esthetic results at 1-year follow-up, emphasizing its efficacy in addressing medial canthal defects secondary to basal cell carcinoma excision.

Background: External dacryocystorhinostomy is considered the gold standard for treating epiphora resulting from nasolacrimal duct obstruction. Despite the success of the procedure, a visible facial skin scar often undermines the surgical outcome. The aim of this study is to prevent visible facial scarring following oculoplastic interventions by improving the insight into the anatomical details of the lacrimal sac fossa (LSF), lacrimo-maxillary suture (LMS), periosteum, and lacrimal diaphragm.
