Epinephrine Injection in Greater Palatine Canal: An Alternative Technique for Reducing Hemorrhage During Septoplasty

Endoscopic Sphenopalatine Ganglion Block Efficacy in the Management of Periorbital Edema and Ecchymosis After Septorhinoplasty

AIM

This study aims to evaluate the efficacy of sphenopalatine ganglion block (SPGB) on postoperative edema and ecchymosis for the patients undergoing septorhinoplasty (SRP).

METHODS

In the study, a total number of 55 participant patients (40% male and 60% female, aged between 18 and 42 years) undergoing hump resection and osteotomies were allocated into 2 groups. The SPGB (+) group consisted of 27 patients who underwent SPGB, while the SPGB (-) group consisted of 28 patients who underwent SRP without SPGB. On the first, third, and seventh postoperative days (POD1, POD3, POD7), the score marks of periorbital edema and ecchymosis of the patients were evaluated. Additionally, postoperative upper eyelid edema and upper eyelid ecchymosis as well as lower eyelid edema, and lower eyelid ecchymosis on POD1, POD3, POD7 were evaluated. A comparison with regard to intraoperative bleeding, surgical field, and operation time between the 2 groups was also conducted.

RESULTS

Upper eyelid edema, upper eyelid ecchymosis, lower eyelid edema, lower eyelid ecchymosis on POD 1, 3, 7 were found to be significantly lower in SPGB (+) group in comparison to SPGB (-) group (P < 0.001). Intraoperative blood loss and surgical field were found to be significantly lower in SPGB group (+) than in SPGB (-) group (P < 0.00). The operation time was not found statistically significant between the 2 groups (P = 0.212).

CONCLUSION

Sphenopalatine ganglion block is a safe and effective way of reducing postoperative edema and ecchymosis after SRP. Besides, it provides a better surgical field and reduced bleeding intraoperatively.

The effectiveness of endoscopic sphenopalatine ganglion block in management of postoperative pain after septal surgery

BACKGROUND

This study evaluated the effect of bilateral endoscopic sphenopalatine ganglion block (SPGB) for management of postoperative pain in patients undergoing septoplasty.

METHODS

Sixty septoplasty patients (51.7% male, 48.3% female, aged 18 to 45 years) were randomly assigned to general anesthesia (GA) alone (control) (n = 30) or GA plus endoscopic SPGB (n = 30). Demographic data, duration of surgery, blood loss, postoperative visual analogue scale (VAS) pain scores (upon arrival at the postanesthesia care unit [PACU] and 2, 6, 12, and 24 hours after surgery), overall analgesic usage (end of 24 and 168 hours after surgery), overall satisfaction with the pain control (end of 24 and 168 hours after surgery), and complications (bleeding, nausea and vomiting, and visual disturbance) were recorded.

RESULTS

Pain scores upon arrival to the PACU and 2, 6, 12, and 24 hours after surgery were significantly lower in the SPGB group compared to the control group (p < 0.001). Moreover, the SPGB group had significantly lower analgesic requirements and higher satisfaction scores with their pain control at the end of 24 and 168 hours after surgery compared to the control group (p < 0.001). The 2 groups significantly differed in terms of intraoperative blood loss (p = 0.024), and surgery time was longer in the SPGB group compared to the control group (p < 0.001).

CONCLUSION

SPGB with bupivacaine is a safe and effective method to reduce pain after septoplasty, and it is a cost-effective alternative to high doses of analgesics.

Perioperative local anaesthesia for reducing pain following septal surgery

BACKGROUND

Septal surgery is a well-established procedure used to treat nasal obstruction due to deviation of the nasal septum, which is carried out under local or general anaesthesia. Local anaesthesia is used for postoperative pain control, but its effectiveness and safety are unclear.

OBJECTIVES

To assess the effectiveness of perioperative local anaesthesia for reducing pain in septal surgery and to evaluate the risk of associated complications.

SEARCH METHODS

The Cochrane ENT Information Specialist searched the Cochrane ENT Trial Register; Central Register of Controlled Trials; Ovid MEDLINE; Ovid Embase; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 9 January 2018.

SELECTION CRITERIA

Randomised controlled trials and cluster-randomised controlled trials involving adults or children (or both) who underwent septal surgery. We included studies comparing local anaesthesia versus no treatment/placebo. We also included studies comparing different types of local anaesthesia to each other (i.e. local injection, the addition of an anaesthetic agent to nasal packing, where used, and sphenopalatine ganglion block).

DATA COLLECTION AND ANALYSIS

We used the standard methodological procedures expected by Cochrane. The primary outcome was postoperative pain intensity at 12, 24 and 48 hours measured by visual analogue scale (VAS) or another pain outcome tool including numerical or verbal rating scales. Secondary outcomes were requirement for additional analgesia, duration of hospitalisation and adverse effects (postoperative bleeding and postoperative vomiting). We used GRADE to assess the quality of the evidence for each outcome; this is indicated in italics.

MAIN RESULTS

We included seven randomised controlled trials involving 493 participants. In all studies the participants were adults undergoing septoplasty. These studies were heterogeneous and the quality of the body of evidence ranged from low to very low. Few of the studies provided reliable data for the primary outcome in this review.Local anaesthetic injection versus no treatment/placeboTwo studies (142 participants) compared local anaesthetic injection versus placebo but these studies did not report postoperative pain at 12, 24 or 48 hours. It is unclear whether local anaesthetic injection changed the risk of vomiting (odds ratio (OR) 3.10, 95% confidence interval (CI) 0.12 to 79.23; 60 participants; one study) (low-quality evidence). Neither study reported the requirement for additional analgesia, duration of hospitalisation or uncontrollable postoperative bleeding.Local anaesthetic application via nasal packing versus no packing/packing with placeboFour studies (301 participants) used nasal packing postoperatively and compared the addition of local anaesthetic to the pack versus packing with a placebo added. Compared with packing with placebo, the addition of local anaesthetic to nasal packing reduced the pain score on a VAS (ranging from 0 to 100) at 12 hours (mean difference (MD) -16.95, 95% CI -22.27 to -11.62; 151 participants; two studies; I² = 49%) (low-quality evidence) and at 24 hours postoperatively (MD -7.53, 95% CI -9.76 to -5.29; 268 participants; four studies; I² = 83%) (very low-quality evidence). These studies did not report postoperative pain at 48 hours. The addition of local anaesthetic to nasal packing decreased the requirement for additional analgesia (OR 0.15, 95% CI 0.07 to 0.34; 151 participants; two studies; I² = 15%) (moderate-quality evidence). No studies reported duration of hospitalisation, postoperative vomiting or uncontrollable postoperative bleeding.No studies compared the addition of local anaesthetic to nasal packing versus no packing.Sphenopalatine ganglion block versus no treatment/placeboOne study (50 participants) compared sphenopalatine ganglion block versus no treatment but this study did not report postoperative pain, requirement for additional analgesia, duration of hospitalisation, vomiting or uncontrollable postoperative bleeding.

AUTHORS' CONCLUSIONS

The addition of local anaesthesia to nasal packs (if these are being used) following septal surgery may reduce postoperative pain within the first 12 hours, compared to nasal packing with a placebo added. The effect is uncertain at 24 hours because the quality of the evidence is very low. Evidence was lacking for other outcomes, including adverse effects. There is a lack of evidence about the effects of local anaesthesia added to nasal packing compared to no nasal packing. There is also a lack of evidence about the effects of local anaesthesia given by injection and the effects of sphenopalatine ganglion block.
