BACKGROUND: During surgical treatment of lesions involving the skull base, conductive hearing is often sacrificed due to tympanum destruction. This study aimed to develop a method for tympanum reconstruction using a sternocleidomastoid (SCM) flap to preserve conductive hearing during lateral skull base surgery.
METHODS: This study included five patients with lateral skull base lesions who underwent surgery including tympanum reconstruction with an SCM flap between July 2015 and November 2017.
RESULTS: Three patients seen with facial nerve schwannoma, and two had paraganglioma of the head and neck. All patients' inferior and posterior tympanic walls were resected; the tympanum and ossicular chain were reconstructed with an SCM flap and prosthesis. The mean postoperative air-bone gap was 14 dB. No lesion recurrences were observed until the last follow-up.
CONCLUSION: The SCM flap is effective in preserving conductive hearing through reconstruction of the inferior and posterior tympanic walls in lateral skull base surgery.
