Sydney Facial Nerve Clinic: experience of a multidisciplinary team.

BACKGROUND

The Sydney Facial Nerve Clinic (SFNC) is a multidisciplinary clinic established in 2015, consisting of surgeons (otolaryngologists, head and neck and plastics/reconstructive), physiotherapists and speech pathologists.

METHODS

We reviewed patients who attended the SFNC in the first 3 years and who had their symptoms recorded using the Facial Disability Index, and clinical staging recorded utilising the House-Brackmann (HB) score, Sydney Facial Nerve Score and Sunnybrook Facial Grading System (SFGS).

RESULTS

Between May 2015 and June 2018, 145 patients attended the clinic. Mean age was 44.6 ± 17.3 years with 94 (64.8%) females. Most referrals came from general practitioners (n = 75, 54.5%). The most common aetiology was iatrogenic injury (n = 55, 37.9%), followed by Bell's palsy (n = 48, 33.1%), congenital (n = 11, 7.6%), herpes zoster oticus (n = 9, 6.2%), trauma (n = 9, 6.2%) and other (n = 13, 9.0%). The median HB was 4, the mean Sydney score 7.3/15 and the mean SFGS was 45/100. Patients with iatrogenic causes had the worse facial nerve scoring in HB, Sydney and SFGS. Patients with congenital aetiology reported the least symptoms on Facial Disability Index (P < 0.001). Most patients were recommended non-surgical management (n = 92, 64.3%); 51 (35.7%) were referred for botulinum toxin + facial physiotherapy, 25 (17.2%) for physiotherapy alone, seven (4.9%) for botulinum toxin alone and nine (6.3%) for conservative management. Fifty-one patients (35.7%) were recommended surgery, generating 75 procedures; 24 oculoprotective, 22 static, 12 gracilis transfers, 10 temporalis myoplasties and seven nerve transfers.

CONCLUSION

Iatrogenic injuries are the most common presentation for this clinic and have a more severe clinical presentation. Most patients presenting to the SFNC were managed non-surgically.
