Efficacy of 4% tetracaine gel and lidocaine-prilocaine cream in reducing local anesthetic injection pain in upper eyelid blepharoplasty: a randomized, single-blinded, controlled trial.
BMC Ophthalmol
December 2024
Department of Ophthalmology, The Second Hospital of Dalian Medical University, Dalian, Liaoning Province, China.
Background: The injection of local anesthetics, an extremely painful procedure, leads to a reduction of patients' acceptance.
Objective: To investigate the efficacy and adverse reactions of 4% tetracaine gel (TG) and lidocaine-prilocaine cream (LPC) on reducing the local anesthetic injection pain for upper eyelid blepharoplasty.
Methods: Sixty participants were equally divided into three groups.

Facial nerve schwannomas (FNSs) eroding through the external auditory canal (EAC) are unusual and present difficult management options.When facial nerve function is normal, observation is generally recommended.If the tumor completely obstructs the EAC creating a conductive hearing loss as in this case, mapping of the motor fibers of the facial nerve may be considered with partial resection to alleviate the conductive hearing loss.

Article Synopsis
- The study investigates the supratemporal retrobulbar block as an anesthetic technique in cats, addressing its effectiveness and injection methods.
- A modified injection of a specific mixture was performed on cadavers, showing a high success rate in contrast agent spread and good distribution around the optic nerve.
- In a clinical setting with 12 cats, the retrobulbar group experienced fewer anesthetist interventions compared to the control group, indicating a potential advantage of the supratemporal approach for surgeries.
