Outcomes of 8 × 8 mm osteotomy in powered external dacryocystorhinostomy.

ABSTRACT:

Purpose

To study the endoscopic ostium characteristics and outcome of 8 × 8 mm osteotomy in external dacryocystorhinostomy (DCR) using the microdrill system.

Methods

This prospective interventional pilot study was performed on 40 eyes of 40 patients with primary acquired nasolacrimal duct obstruction (NLDO) from June 2021 to September 2021 in patients undergoing external DCR. An 8 × 8 mm osteotomy was performed using round, cutting burr attached to a microdrill system. Success was defined as patent ostium on lacrimal syringing (anatomical) and a Munk score <3 (functional) at 12 months. Postoperative endoscopic ostium evaluation was done using a modified DCR ostium (DOS) scoring system at 12 months.

Results

The mean age of the study participants was 42.41 ± 11.77 years and the male-to-female ratio was 1:4. The mean duration of surgery was 34.15 ± 1.66 minutes and that for osteotomy creation was 2.5 ± 0.69 minutes. The mean intraoperative blood loss was 83.37 ± 11.89 ml. Anatomical and functional success rates were 95% and 85%, respectively. The mean modified DOS score was "excellent" in 34 patients (85%), "good" in 1 patient (2.5%), "fair" in 4 patients (10%), and "poor" in 1 patient (2.5%). Complications included nasal mucosal injury in 10% (4/40) of patients, complete cicatricial closure of ostium in 2.5% (1/40), incomplete cicatricial closure in 10% (4/40), nasal synechiae in 5% (2/40), and canalicular stenosis in 2.5% (1/40).

Conclusion

An 8 × 8 mm-sized osteotomy created by powered drill and covered by lacrimal sac-nasal mucosal flap anastomosis in external DCR is an effective technique that has minimal complications and shorter surgical time.

Project description:ObjectivesTo determine whether administration of local anaesthetic at the site of skin incision during open lacrimal drainage surgery under general anaesthesia alters the total dosage of anaesthetic drugs required during total intravenous anaesthesia (TIVA), and whether it alters postoperative pain and recovery.Study designMasked comparison of a randomized, two-group interventional study.Patients and methodsPatients undergoing unilateral external dacryocystorhinostomy under total intravenous general anaesthesia were recruited from the lacrimal service at Moorfields Eye Hospital between September 2012 and February 2014. The patients were randomised to receive, after induction and stabilisation of general anaesthesia, infiltration of the ipsilateral paranasal tissues with 2.5 ml of 0.5% bupivacaine with 1:100000 epinephrine ("treatment" group), or a sham injection ("control" group); the infiltration was performed about 7 min prior to the skin incision. The infusion rates for propofol and remifentanil were adjusted to maintain a steady intra-operative mean blood pressure of 55-70 mmHg and BIS score of 40-60%. The time taken for extubation of the patient after cessation of TIVA was recorded, and postoperative pain scores (on a Likert scale from 0-10) were taken at regular intervals after extubation. The average intra-operative mean blood pressures, total drug usage, extubation time and pain scores for each of the two groups were compared using two-tail Student's t-testing and Wilcoxon rank sum testing.ResultsThere were 12 patients (7 female; 58%) in the treatment group and 11 (7 female; 64%) in the control group, with similar average age at surgery (59 years treatment, 53 years control; p = 0.38) The average operative time was 45 min in the treatment group (median 42, range 30-55) and 47 min (median 45; range 37-61) in the control group (p = 0.52). The mean dosage of propofol required to maintain satisfactory GA was significantly less in the "treatment" group (89.8 mcg/kg/min) as compared to the "control" group (mean 126 mcg/kg/min) (p = 0.0007). Likewise, remifentanil dosage was significantly less in the "treatment" group (100 ng/kg/min) as compared to controls (259 ng/kg/min) (p = 0.00007). The mean non-invasive blood pressure was consistently lower during surgery in the "treated" group, and showed less intra-operative variation. After surgery, the patients receiving LA had a significantly shorter extubation time (mean time 6.0 min in "treated" group, 12.1 min in "controls"; P < 0.0002) and also significantly lower pain scores at 10, 30, 60, 120 and 180 min after extubation (p < 0.01, p < 0.01, p < 0.01, p < 0.01 and p < 0.05, respectively).ConclusionsIpsilateral infiltration of local anaesthesia containing epinephrine in the paranasal tissues just prior to open dacryocystorhinostomy under total intravenous anaesthesia is associated with a 28% reduction in mean propofol usage, and a 61% reduction in remifentanil usage. LA usage during GA also produces improved and less variable intra-operative mean blood pressures, a significantly shorter extubation time and significantly lower postoperative pain scores.

Project description:PurposeIn the amyoplasia type of arthrogryposis, a reverse pronated grasp pattern is often seen. We hypothesized that repositioning the hands, through distal humerus external rotation osteotomies (DHO), would allow for palm-to-palm grasp without arm cross-over and would improve function and parent/patient satisfaction.MethodsThe medical records of all patients treated surgically for arthrogryposis were reviewed at the Shriners Hospital for Children, St. Louis, MO. From 2012 to 2014, 9 patients (14 extremities) had undergone a DHO. All patients had preoperative and postoperative video recordings of functional activities and we assessed functional changes after osteotomies. Preoperative upper extremity position was graded as 1, palms facing midline; 2, palm facing posterior; and 3, palms facing away from midline. Postoperative Pediatric Outcomes Data Collection Instrument (PODCI) questionnaires were obtained and parent satisfaction was evaluated.ResultsMean patient age at the time of surgery was 6.5 years. Five patients underwent bilateral DHOs. All patients had 3 or fewer additional procedures on an upper extremity during the study period. All patients had an improved resting posture of the upper extremity after DHO surgery, with a mean change of 51° (range, 15°-90°). Grasp pattern was altered in 13 extremities; there was a change in hand position of at least 1 grade and 5 had complete change from 3 to 1, palms facing away from midline to facing toward midline. There was a wide range in postoperative PODCI scores for function, but Happiness scores were high, mean 89 (range, 60-100). Parents universally stated the procedure improved the child's function "a great deal." There were 2 complications: 1 periprosthetic humerus facture with recurrence of the internal rotation and 1 patient with scarring of the triceps requiring tenolysis.ConclusionsThe DHO is an effective procedure for correcting the internal rotation position of the upper extremity in arthrogryposis and the surgery improves hand opposition with minimal complications. Universally, there was perceived improved function with high postoperative PODCI Happiness scores.Type of study/level of evidenceTherapeutic V.
