    Endoscopic Transorbital Surgery: Medial Orbital (Precaruncular) Approach
    (2025-03-08) Lubbe, Darlene
    Access to the ethmoidal arteries is required to ligate the vessels with nasoethmoid traumatic fractures or to assist with haemostasis prior to resecting sinonasal tumours. The Lynch-Howarth incision has been the gold standard to approach these arteries, with the frontoethmoidal suture line said to be the optimal way of finding these arteries. However, this external approach should be replaced by the precaruncular approach to access these arteries for the following reasons: Lynch-Howarth incision •External facial incision can cause cos-metically unacceptable scars •Dissection through skin, subcutaneous tissue, and orbicularis oculi muscle is required with suturing of the incision •Bleeding can be encountered from the angular vessels
