FROM birth the normal method of respiration is by the nose and any interference producing mouth breathing causes considerable local or general impairment of function. The interference is caused by a combination of factors, such as narrowness of the nose often associated with maxillary compression, allergic mucosal swelling, deviated septum, infection, and at times obstructing adenoids. Rapid maxillary expansion is a simple, conservative, but very efficient method of converting mouth breathing back to normal nasal respiration in a high proportion of cases. Rapid maxillary expansion (referred to as RME for this paper) is performed by applying strong pressure to the back teeth over a relatively short period of time causing the maxillae to separate down the intermaxillary suture, without the teeth moving in the bone. This not only changes the dental occlusion, but also widens the nasal cavity.Historical The first record of work on RME was that of Angell in i860, who performed it to provide space for the canines. Since about 1900 there have been many reports (as well listed by Wertz, 1970; McCracken, 1970) of associated medical results, such as improvement in nasal airway, nasal allergy and asthma. The reported results have been very good and quite challenging. For example, Griffiths (1958) and Braun (1966) reported improvement in asthma cases, and Stockfisch (1969) reported the following results in a series of 150 cases aged 6-32 years, 5-15 years after RME 82% Now nose breathing.
