[Treatment of trigeminal neuralgia using controlled differential selective thermorhizotomy].

Personal experience in 35 cases of controlled, partial, selective thermorhizotomy of the trigeminus is referred to in a discussion of its indisputable advantages (abolition of pain, preservation of tactile sensibility, simple method) by comparison with other techniques, and its theoretical basis: selective lesion of the "delta" A and C fibres by exploiting the vulnerability gradient of the nerve fibres to heat.
