Eyelid surgery anesthesia

Anesthesia options

• Local-only anesthesia uses injectable agents such as lidocaine, ropivacaine, prilocaine, bupivacaine or articaine, usually with epinephrine to limit bleeding (PMID 35961926). A randomized trial in 31 patients found ropivacaine caused significantly less intraoperative bleeding than prilocaine (bleeding score 1.71 versus 3.39, P<.0001), with slightly more swelling (PMID 28017546).
• Tumescent local anesthesia (larger-volume, dilute local anesthetic) shortened surgery time, caused less pain, and produced less ecchymosis and erythema at day 7 than standard infiltration in 178 bilateral upper blepharoplasty patients, without changing satisfaction (PMID 33217779).
• Regional nerve block, which avoids injecting the eyelid incision line itself, was used in 6,099 upper blepharoplasty patients with a mean of only 0.9mL of anesthetic per eyelid, no cases of injection-related pseudoptosis, and no complications (PMID 41361143).
• Oral sedation (commonly a benzodiazepine such as midazolam or diazepam) is used for anxious patients undergoing surgery under local anesthesia. In 70 patients randomized to diazepam or midazolam with or without clonidine, midazolam produced deeper sedation than diazepam, and midazolam plus clonidine caused a larger shift in upper eyelid margin position (-1.42mm) than diazepam alone (PMID 20523253).
• Intravenous (IV) sedation, typically propofol-based and titrated by a non-anesthesiologist surgeon or an anesthesia provider, is used for deeper comfort while the patient remains breathing spontaneously (PMID 41291073).
• General anesthesia, with a secured airway, is used for combined or longer procedures, uncooperative patients, and children. A randomized trial of 148 blepharoplasty patients under general anesthesia found a nasopharyngeal airway caused less postoperative sore throat than a laryngeal mask airway (4.0% versus 17.6%, P<.015) and shorter recovery (10.3 versus 12.6 minutes, P<.001) (PMID 33327697).

Office versus surgery center

• A review of 5,316 consecutive cases at one accredited outpatient plastic surgery facility over 6 years found a 0.7% complication rate and no deaths; 77% of complications were hematomas (PMID 12900627).
• Florida's 6-year moratorium-era data found 46 total office-procedure deaths statewide, 20 within the scope of plastic surgery, with board-certified plastic surgeons accounting for under a quarter of those and none since April 2004, against over 600,000 office operations performed in the period (PMID 16932189).
• A national accreditation registry found 23 deaths in 1,141,418 outpatient procedures from 2001-2006; 13 of the 23 were from pulmonary embolism, most often after abdominoplasty (PMID 18594412).
• Comparing 183,914 aesthetic procedures across facility types in the CosmetAssure database, complication rates were 1.3% in office-based surgical suites, 1.9% in ambulatory surgery centers, and 2.4% in hospitals; office-based suites carried lower adjusted risk than either (RR 0.67 versus ASC, RR 0.59 versus hospital, both P<.01) (PMID 27553613).
• A 286,826-procedure analysis of the TOPS registry (2008-2016) found a 5.7% overall adverse event rate, with no significant difference between office-based facilities (56.2% of cases) and ambulatory surgery centers (43.8%); general anesthesia itself was one factor associated with adverse events (PMID 36877624).
• A review of office-based anesthesia outcomes concludes that improved safety in the office setting reflects careful patient selection: poor candidates for outpatient office procedures include those with active infection, cardiovascular disease, coagulopathy, insulin-dependent diabetes, obesity, obstructive sleep apnea, poorly controlled hypertension or thromboembolic disease (PMID 31483329).
• A review of 32 patients who had cardiac arrest during or after office-based cosmetic surgery (2009-2016) found 41% mortality despite extracorporeal life support in most cases, and hypoxic brain injury in over half of survivors (PMID 32919449).

Results and evidence

Pain and comfort with local anesthesia

• A network meta-analysis of 11 randomized trials (521 patients, 917 eyes) in minor oculoplastic surgery found bicarbonate-buffered lidocaine with epinephrine gave the lowest injection pain by preference ranking, though the authors rated confidence in this finding as very low (PMID 35961926).
• A 288-patient, 9-group randomized trial in upper blepharoplasty found buffered 2% lidocaine with sodium bicarbonate gave the lowest pain scores at the earliest time point of any combination tested, and buffered mixtures remained lower than unbuffered lidocaine-epinephrine at 30 minutes (PMID 37338328).
• A smaller, earlier trial found pre-cooling the skin for 2 minutes gave injection-pain relief similar to buffered lidocaine, with less postoperative pain at 2-4 hours and 24 hours than buffering, though no difference by 2 days or 1 week (PMID 26329852).
• Topical 4% tetracaine gel reduced injection pain more than lidocaine-prilocaine cream after 60 minutes of application in 60 patients, but caused cutaneous reactions more often (72.5% versus 35%) (PMID 39702190).
• A stepwise local infiltration technique with increasing epinephrine concentration, tested in 184 patients, significantly lowered pain scores, reflexive lacrimation and day-7 ecchymosis, erythema and swelling compared with conventional infiltration, and raised satisfaction (P=.016) (PMID 40588641).
• A case series of 20 patients found a fine-gauge (Nanosoft) infiltration needle gave significantly lower pain scores and less postoperative ecchymosis and edema than a traditional needle (PMID 37225141).

Sedation and general anesthesia outcomes

• A prospective, non-randomized cohort comparing deep IV sedation to general anesthesia in facial plastic surgery found the sedation group had less postoperative nausea and vomiting (21.7% versus 50%, P=.04), shorter emergence time (4 versus 13 minutes, P<.001), and higher quality-of-recovery scores (PMID 34972006).
• A retrospective audit of 4,397 consecutive propofol-based IV sedations for office-based esthetic surgery, restricted to ASA class I-II patients, reported zero major cardiopulmonary events, hypertensive episodes needing treatment in 1.0%, and no unplanned hospital admissions (PMID 41291073).
• A prospective, depth-adjusted IV anesthesia protocol in 135 consecutive office-based cases reported no major cardiorespiratory events, a median satisfaction score of 5 out of 5 (68.1% of patients), and median recovery time of 22 minutes (PMID 42203962).
• A sufentanil sublingual tablet used for minimal sedation in 31 awake plastic surgery patients (including blepharoplasty) produced no vital sign instability, mild nausea in 10%, and a mean recovery time of 15 minutes (PMID 35350112).
• A multicenter randomized trial of 132 revisional upper blepharoplasty patients found adding IV oliceridine and alfentanil to local anesthesia lowered intraoperative pain scores, cut reflex tearing (6.9% versus 75.0%, P<.001) and excessive movement (14.6% versus 80.0%, P<.001), and raised 3-month FACE-Q comfort scores (88.6 versus 76.4, P<.001) versus local anesthesia alone (PMID 42310080).
• Comparing dexmedetomidine infusion to midazolam-fentanyl bolus sedation in 250 blepharoplasty-with-mid-cheek-lift patients, the dexmedetomidine group used less local anesthetic, reported less postoperative pain, and had fewer hypoxia episodes and less minor hematoma formation (PMID 37373795).
• Dexmedetomidine combined with remifentanil for lower eyelid blepharoplasty, compared with local anesthesia plus IV midazolam, produced less intraoperative agitation (24 of 25 patients agitation-free versus 18 of 25 with agitation in the control group) and higher patient and surgeon satisfaction (96%) (PMID 25112009).
• Low-concentration (30%) nitrous oxide added to local anesthesia for ptosis surgery in 54 patients lowered intraoperative pain scores and heart rate, raised oxygen saturation, and shortened operating time, with no nausea or other side effects (PMID 33530174).
• Comparing local and general anesthesia for posterior-approach congenital ptosis repair in 21 patients (23 eyelids), postoperative eyelid height (MRD1) and an 85% surgical success rate were similar between the two, with no complications in either group; general anesthesia remains the option for patients unable to tolerate awake surgery (PMID 38602026).
• A prospective, in-office oral sedation protocol compared with ambulatory surgery center (ASC) care using IV sedation or general anesthesia in 253 oculoplastic patients found no significant difference in patient- or physician-rated experience between settings, though more ASC patients said they would have preferred in-office care (34.9% versus 19.2%, P=.006), and no safety complications occurred in either setting (PMID 37972952).
• Office-based oral sedation in 199 patients undergoing 283 facial aesthetic procedures, including blepharoplasty and browlift, in ASA class I-II patients produced no major complications or sedation issues (PMID 26446058).
• A premedication trial in 182 upper blepharoplasty patients found oral midazolam alone most effectively reduced anxiety before, during and after surgery; adding EMLA topical anesthetic did not further reduce injection pain, while adding paracetamol with codeine reduced postoperative pain and painkiller use (PMID 38465153).

Risks and complications

• The oculocardiac reflex, trigeminal-vagal-mediated bradycardia or dysrhythmia during ocular manipulation, occurred in 25 of 100 blepharoplasty patients in the original description of the phenomenon; it was more likely in young, anxious female patients with a cardiac history operated on under light anesthesia with aggressive fat pad traction, and required releasing traction to let heart rate recover (PMID 2911623).
• A case series reported permanent or residual visual loss after cosmetic blepharoplasty performed under local anesthesia containing epinephrine alone, with causes including angle-closure glaucoma, which fully resolved with treatment, and posterior ischemic optic neuropathy, which left a residual visual field defect (PMID 35265512).
• Among 302 patients on antithrombotic therapy undergoing eyelid and periocular surgery under local anesthesia, 77 (25.5%) continued their medication through surgery; there were no major bleeding complications and one self-resolving postoperative bleed, with no significant difference in bleeding rate versus patients not on antithrombotics (PMID 41672423).

Recovery

• Recovery after local-only or lightly sedated eyelid surgery is typically measured in minutes: 15 minutes after sufentanil sublingual tablet sedation (PMID 35350112), a median of 22 minutes under a depth-adjusted IV protocol (PMID 42203962), and prolonged recovery (over 30 minutes) in only 1.7% of a 4,397-case IV sedation series (PMID 41291073).
• Deep IV sedation produced shorter emergence time than general anesthesia in facial plastic surgery (4 versus 13 minutes) (PMID 34972006), and a nasopharyngeal airway shortened recovery compared with a laryngeal mask airway under general anesthesia for blepharoplasty (10.3 versus 12.6 minutes) (PMID 33327697).
• Regional nerve block anesthesia for upper blepharoplasty was reported to shorten recovery time compared with traditional local infiltration across 6,099 cases (PMID 41361143).

Combined procedures

• Anesthesia choice tracks procedure scope: office-based oral sedation and local-only protocols cover routine upper and lower blepharoplasty and ptosis repair, while combined brow lift, midface or facelift procedures more often move to IV sedation or general anesthesia and a licensed facility (PMID 26446058). General anesthesia itself was independently associated with adverse events in the 286,826-procedure TOPS registry analysis above (PMID 36877624).
• Procedure-specific detail on combining blepharoplasty, ptosis repair and brow lift is covered in research/science/upper-blepharoplasty.md, research/science/blepharoptosis-repair.md, research/science/browpexy-and-direct-brow-lift.md, research/science/endoscopic-brow-lift.md and research/science/temporal-and-lateral-brow-lift.md rather than repeated here.

Current questions

• Whether buffering a local anesthetic or simply pre-cooling the skin gives better pain control is unsettled: one RCT favored buffered lidocaine (PMID 37338328), an earlier trial found pre-cooling comparable (PMID 26329852), and a network meta-analysis rated the overall evidence confidence for any single best local anesthetic combination as very low (PMID 35961926).
• Whether office-based surgical suites are as safe as, or safer than, ambulatory surgery centers is debated: one large CosmetAssure analysis found lower complication risk in office-based suites (PMID 27553613), while the larger TOPS registry analysis found no significant difference between the two settings (PMID 36877624); a review attributes safety in either setting to patient selection rather than the location itself (PMID 31483329).
• Rare but serious visual loss after blepharoplasty under local anesthesia alone, without any sedation, remains a reported risk that predates any airway or sedation-related explanation (PMID 35265512).
• Newer multimodal IV analgesics (oliceridine, alfentanil, sufentanil sublingual tablets) show promising early trial data for comfort during local anesthesia, but have not yet been compared directly against established oral or deeper IV sedation protocols in eyelid surgery (PMID 42310080), (PMID 35350112).

Terms

• Local (infiltrative) anesthesia: anesthetic injected directly into the surgical site, without sedation (PMID 35961926).
• Tumescent local anesthesia: injection of a larger volume of dilute local anesthetic into the surgical plane (PMID 33217779).
• Buffered lidocaine: lidocaine mixed with sodium bicarbonate to raise its pH and reduce injection pain (PMID 37338328).
• Regional nerve block: anesthetic injected around a nerve supplying the surgical area rather than into the incision line itself (PMID 41361143).
• Oral sedation (premedication): a sedative, usually a benzodiazepine, taken by mouth before surgery done under local anesthesia (PMID 20523253).
• Monitored anesthesia care (IV/conscious sedation): sedation delivered intravenously with continuous monitoring while the patient breathes without assistance (PMID 41291073).
• General anesthesia: anesthesia producing unconsciousness, with a secured airway (PMID 33327697).
• Oculocardiac reflex: a trigeminal-vagal reflex causing bradycardia or dysrhythmia during eyelid or orbital manipulation (PMID 2911623).
• ASA physical status class: the American Society of Anesthesiologists' scale (I-VI) for a patient's preoperative health, used to select candidates for office-based anesthesia (PMID 41291073).
• Office-based surgical suite (OBSS): a procedure room inside a physician's office, distinct from a licensed ambulatory surgery center (ASC) or hospital (PMID 27553613).
• Posterior ischemic optic neuropathy: optic nerve damage from inadequate blood flow, a rare cause of vision loss after eyelid surgery (PMID 35265512).
