Dirk Hermes. Samer G. Hakim, Peter Siegshowed that a similar teehnique significantlyreduced <strong>in</strong>traoperative treatment anxiety <strong>and</strong>postoperative consumption of analgesicsafter surgical removal of third molars underloeal anaesthesia. Ghoneim <strong>and</strong> co-workers(2000) described identical anxioiytic effectsof preoperative Tape Recorded <strong>Hypnosis</strong><strong>in</strong> the experimental group of a study whichunderwent dental extraetions or surgical removalof teeth under local anaesthesia <strong>and</strong>eonseious sedation (fentanyl. midazolam.nitrous oxide). For no apparent reason therewas also a significant <strong>in</strong>crease of postoperativevomit<strong>in</strong>g <strong>in</strong> the experimental group.The <strong>in</strong>tent of own <strong>in</strong>vestigations was to ga<strong>in</strong><strong>in</strong>formation about the effeets of st<strong>and</strong>ardisedhypnosis dur<strong>in</strong>g a wider range of oral <strong>and</strong>maxillofaeial operations on locally anaesthetised<strong>and</strong> non-sedated patients. The basic underly<strong>in</strong>gquestions were, <strong>in</strong> how far subjective<strong>and</strong> cl<strong>in</strong>ical effects of such a procedurejustify the <strong>in</strong>tensification of its therapeuticuse <strong>in</strong> oral <strong>and</strong> maxillofaeial surgery <strong>and</strong> furthermore,require scientific evaluation us<strong>in</strong>gcontrolled cl<strong>in</strong>ical studies.In this respect, systematic applications ofhypnosis <strong>in</strong> our department <strong>in</strong>dicated <strong>in</strong>terest<strong>in</strong>gperspectives. <strong>Hypnosis</strong> is a suggestiveprocedure for perioperative stress reduetionshow<strong>in</strong>g a high degree of theoretical <strong>and</strong>practical patient consent. Procedural st<strong>and</strong>ardisationfor special purposes (e.g. tape recordedhypnosis vs. live hypnosis) m<strong>in</strong>imisesnecessary ehanges <strong>in</strong> the surgical sett<strong>in</strong>g <strong>and</strong>reduces variables <strong>in</strong> the design of possiblecl<strong>in</strong>ical studies. Meta-analysis of the adjunctiveuse of hypnosis <strong>in</strong> surgery (Montgomeryct al., 2002) proved that such st<strong>and</strong>ardisationis not accompanied by reduced effectivenessof hypnosis. Interpretation of our maxillofacialstudy supports this thesis as the datamatches the success rates of <strong>in</strong>traoperativehypnosis <strong>in</strong> the literature. Furthermore, itshows that the specific treatment situation <strong>in</strong>oral <strong>and</strong> maxillofacial surgery does not createa negative <strong>in</strong>fiuenee on trance ability <strong>and</strong><strong>in</strong>tensity of patients.Positive <strong>in</strong>traoperative effects of hypnosis<strong>in</strong>clude sedation, anxiolysis. <strong>in</strong>hibited motorskills <strong>and</strong> <strong>in</strong>creased tolerance towardsphysically <strong>and</strong> psychologically dem<strong>and</strong><strong>in</strong>gsurgieal procedures. Overall preparationtime (<strong>in</strong>formation, seed<strong>in</strong>gs <strong>and</strong> <strong>in</strong>duction)of approximately \5 m<strong>in</strong>utes, complete postoperativereorientation of the patient with<strong>in</strong>less than 1 m<strong>in</strong>ute <strong>and</strong> low technical costsare further advantages of hypnosis <strong>in</strong> direetcomparison with established pharmaeologiealprocedures.Nevertheless, hypnosis cannot serve as a serioussubstitute for pharmacological sedationor general anaesthesia. Specific limitations<strong>and</strong> contra<strong>in</strong>dications have to be taken <strong>in</strong>toaecount. surgeons with detailed knowledge,<strong>in</strong>dividual patient preparation <strong>and</strong> specialtreatment modalities are necessary. Its therapeuticuse is limited to mentally healthy <strong>and</strong>fully co-operative patients who are at leastopen to the procedure.ConclusionIntraoperative hypnosis is an <strong>in</strong>terest<strong>in</strong>gsupplementation to anxioiytic <strong>and</strong> sedativepharmacological procedures. It showedseveral positive <strong>in</strong>tra- <strong>and</strong> postoperative effeetsfor both patient <strong>and</strong> surgeon dur<strong>in</strong>g athree-year evaluation period. Its potentialfor surgeons should be evaluated <strong>in</strong> furthercl<strong>in</strong>ical studies.Correspond<strong>in</strong>g author:Dirk Hermes, M.D..
