Trainee-trainer outcomes in mastoid surgery: a comparative study.

BACKGROUND

Mastoid exploration remains an advanced, mainstay operation within ENT, in which the surgical trainees' role has been debated. This audit compares mastoid exploration outcomes between trainees and consultants.

METHODS

Cortical mastoidectomy, atticotomy, atticoantrostomy, modified radical mastoidectomy, combined-approach tympanoplasty and revision mastoidectomy operations performed between 2009 and 2020 were reviewed. Complications assessed were: facial palsy, labyrinth injury, dead ear, disease recurrence and time to recurrence. The chi-square test was used to determine significant associations.

RESULTS

A total of 118 operations were surveyed. Thirty-five per cent of procedures (n = 41) were performed by trainees under supervision, and 65 per cent (n = 77) were carried out solely by consultants. Patients from 5 per cent of trainees' operations (n = 2) developed recurrence, compared with 7.8 per cent of consultants' (n = 6) (p = 0.55). No other complications developed in either group.

CONCLUSION

The results corroborate those of other studies, indicating no significant increase in complication rate from consultants to trainees. Trainees likely completed less complicated cases. The stepwise incorporation of trainees did not compromise patient safety.
