Comparison of Postoperative Pain With Two Different Types of Local Anesthesia in Surgery for a Drooping Eyelid
Conjunctival Mullerectomy is a well known procedure used to correct upper lid ptosis via a posterior approach. Patients who undergo this procedure are often given local anesthesia to alleviate intraoperative and postoperative pain. Local anesthesia can be given via frontal nerve block or subconjunctival injection combined with sedation in most cases. Both techniques are currently acceptable options for local anesthesia, however postoperative pain has not been systematically evaluated between these two techniques.
The investigators aim to compare intra-operative and postoperative pain with these two techniques in patients undergoing conjunctival Mullerectomy for ptosis repair. Patients will be randomized to receive local anesthesia via frontal nerve block or via subconjunctival injection. In addition, the investigators will measure the surgical outcomes of the ptosis surgery with standard measures.
|Blepharoptosis||Procedure: Frontal nerve block with 2% lidocaine with 1:100,000 dilution of epinephrine Procedure: Subconjunctival injection of 2% lidocaine with 1:100,000 dilution with epinephrine|
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Participant, Outcomes Assessor
Primary Purpose: Supportive Care
|Official Title:||Comparison of Postoperative Pain With Two Different Types of Local Anesthesia in Surgery for a Drooping Eyelid|
- Pain control [ Time Frame: 24 hour after surgery ]Patients will be asked to complete a survey regardning pain assessment twenty-four hours after completion of surgery.
- Efficacy of ptosis surgery [ Time Frame: 2 months ]Standard measures include marginal reflex distanced, palpebral fissure and levator fucntion will be used to assess the efficacy of the ptosis surgery and compared to the type of anesthesia the patient was given.
- Pain Control [ Time Frame: 1 hour after surgery ]completion of survey to assess pain after surgery has been completed.

Active Comparator: Frontal Nerve Block
Patients will receive a frontal nerve block for anesthesia
Procedure: Frontal nerve block with 2% lidocaine with 1:100,000 dilution of epinephrine
Frontal Nerve Block 5 cc will be administered preoperatively once.
Active Comparator: Subconjucntival Injection
Patients will receive a subconjunctival injection for anesthesia
Procedure: Subconjunctival injection of 2% lidocaine with 1:100,000 dilution with epinephrine
Patients will receive a 1.5 cc dose of subconjunctival lidocaine as above
