Stable long-term outcomes after cochlear implantation in subjects with TMPRSS3 associated hearing loss: a retrospective multicentre study

Table 3 Pre-implantation pure tone average (PTA) and phoneme scores of the implanted ears in the TMPRSS3-group

	Pre-implantation PTA_0.5-4kHz		Pre-implantation Phoneme score at 70 dB		CI-use post-implantation
		PTA_0.5-4kHz (dB HL)^**		Phoneme score at 70 dB (%)^**	CI-user	Non-/limited CI-user
Hearing aid prior to implantation (N = 21, 64%)	Aided PTA (N = 21)	59 ± 16	Aided phoneme score (N = 14)	22 ± 27	20 (95%)	1 (5%)
No-hearing aid prior to implantation (N = 12, 36%)	Unaided PTA (N = 12)	82 ± 15	Unaided phoneme score (N = 19)	41 ± 26	9 (75%)	3 (25%)
Best-aided/unaided* (N = 33, 100%)	Best-aided/unaided* (N = 33)	67 ± 19	Best-aided/unaided* (N = 33)	33 ± 28	29 (88%)	4 (12%)

PTA indicates pure tone average; CI, cochlear implant
^*The best-aided/unaided scores were calculated from aided scores from patients using hearing aids prior to implantation in combination with the unaided scores from patients not using hearing aids prior to implantation. When aided scores from patients using hearing aids were not available, unaided scores were also used
^**PTA_0.5-4kHz and phoneme scores are displayed as mean ± standard deviation
