Objectives: Nasal bone fractures are a common presentation to the Ear, Nose and Throat (ENT) surgeon. Simple, closed fractures are assessed and considered for closed manipulation under anesthesia (MUA #nasal bones). Most departments perform this under general anesthesia (GA). Our protocol changed in the face of COVID-19, where procedures were alternatively performed under local anesthesia (LA) in the clinic, to cope with lack of elective theater capacity during the pandemic, while still allowing a nasal fracture service to take place. We present postoperative patient outcomes on breathing and shape, comparing GA versus LA.
Methods: Patient records retrospectively analyzed (January 2020-August 2020), and patients undergoing MUA #nasal bones interviewed by telephone after one month. Exclusion criteria were open injuries or depressed nasal bones requiring elevation. Breathing and shape scores were evaluated subjectively using a Likert scale (1 = very unsatisfied, 5 = very satisfied).
Results: Two hundred five nasal injury referrals were made (21 MUA #nasal bones under GA and 27 under LA). Manipulation under anesthesia #nasal bones significantly improved both breathing satisfaction scores (GA; 2.88 ± 0.24 to 4.06 ± 0.23, P < 0.05; LA; 2.86 ± 0.22 to 3.77 ± 0.27, P < 0.05) and aesthetic scores (GA; 2.00 ± 0.21 to 3.94 ± 0.23, P < 0.05; LA; 1.64 ± 0.19 to 3.59 ± 0.28, P < 0.05) in both GA and LA groups. There was no statistically significant difference between LA and GA in postoperative outcomes. There was a trend toward greater satisfaction for GA, though this was not statistically significant and may be impacted by the rate of cartilaginous deformity in the LA group. Both techniques were well tolerated and most patients would repeat the procedure in hindsight.
Conclusions: Local anesthesia could provide a safer, cheaper, and satisfactory alternative for performing MUA #nasal bones in the clinic for selected patients, particularly with reduction of elective theater capacity in the event of further COVID-19 surges. We recommend training junior ENT surgeons to perform this procedure under supervision with adequate protective measures.
