Discussing nupercaine as a local anesthetic in otolaryngology, Egan82 states that he has found that a 1: 1,000 concentration appears to be a satisfactory anesthetic for infiltration previous to tonsillectomy. The duration of the anesthesia produced exceeds that produced by 1 per cent procaine hydrochloride. No evidence of local irritation, delayed healing or systemic intoxication was noted after the use of nupercaine ciba.
A new soft palate retractor and an adenoid punch for removing the remnants of adenoids were devised by Love.83 By means of the soft palate retractors a direct view of the epipharynx can be obtained. When remnants of adenoids are present, they can be removed easily with the basket punch. The soft palate retractor can also be used when inserting a postnasal pack.
A new soft palate retractor permitting adenoidectomy under direct vision was devised by Gidoll.84 The instrument
