ObjectiveTransconjunctival approach to the lower 1/3 of the orbit is commonly used to avoid transcutaneous incisions when surgical access is needed. A lateral canthotomy is used in conjunction with this approach if increased lateral exposure is required. A major disadvantage to the lateral canthotomy is difficulty in re-suspension of the lateral canthal tendon that can lead to unaesthetic outcomes. The present report describes 2 cases of a lateral tarsal incision or as we decided to call it a 'lateral tarsotomy' technique. This simple approach is used to aide with increasing lateral access orbit without the need for a lateral canthotomy.Study DesignTwo patients presented with internal orbital wall trauma requiring repair were accessed with a transconjunctival approach in conjunction with a lateral tarsotomy. They were followed at 1 week, 1 month, and 3 months to document the development of possible unaesthetic and poor functional outcomes.ResultsExcellent cosmetic results were observed with no noticeable deformity at the tarsotomy site. There was no evidence of ectropion, entropion, scleral show and visible scars.ConclusionThe above results suggest that the lateral tarsotomy approach is a practical alternative to a lateral canthotomy when increased lateral exposure is required.
