Lower blepharoplasty is a challenging aesthetic procedure. Despite advances in clinical and neuroanatomical studies related to orbicularis oculi muscle innervation, no study has examined its histopathological aspects in different lower blepharoplasty procedures. This study aimed to assess changes in the pretarsal muscle complex in patients treated with transcutaneous lower blepharoplasty with orbicularis myotomy versus those treated with transconjunctival blepharoplasty without myotomy.
