Many clinical trials assessing the effectiveness of hypnosis have been conducted in recent years, some of which show that hypnosis reduces pain perception better than drug treatments administered to control groups, and that it is at least as effective as other complementary therapies (such as massage, acupuncture, yoga). However, their conclusions are limited by a significant risk of bias, and further studies with rigorous methodology remain necessary. The hypothesis of this study is that hypnosis support methods can reduce anxiety in patients requiring facial surgery under local anaesthesia, and thus improve their medical management.
The purpose of this study is to evaluate the effectiveness of hypnosis support on the patient's state of anxiety before and after outpatient surgery under local anaesthesia in the Maxillofacial Surgery Department.
Patient treated under local anaesthesia in the Maxillo Facial Surgery department with ultra-short circuit
Patient undergoing face surgery
Patient who has received appropriate information and has provided informed consent
Adult patient ≥ 18 years old
Patient under general anaesthesia
Patients treated in conventional inpatient care or in the traditional ambulatory circuit
Patient under guardianship or trusteeship
Minor patient < 18 years of age
Parallel
State-Trait Anxiety Inventory ("Spielberger Self-Assessment Questionnaire")
Other interventionPatients will be given, a State-Trait Anxiety Inventory ("Spielberger Self-Assessment Questionnaire") that will be collected on the same day. Each patient's initial anxiety score will be calculated so as to select only patients who are at least lightly anxious about their management (score ≥ 36).
hypnosis techniques
Procedure/SurgeryPatients requiring facial surgery under local anaesthesia in an ultra-short circuit will benefit from experimental management based on hypnosis techniques.
local anaesthesia
Procedure/SurgeryPatients requiring facial surgery under local anaesthesia in an ultra-short circuit will benefit from conventional management (local anaesthesia).
variation in Spielberger's anxiety self-assessment questionnaire score between the patient's arrival in the operating room and his departure
The State-Trait Anxiety Inventory (STAI) (or Spielbergers's anxiety self-assessment questionnaire) is a psychological inventory based on a 4-point Likert scale and consists of 40 questions on a self-report basis. The STAI measures two types of anxiety - state anxiety, or anxiety about an event, and trait anxiety, or anxiety level as a personal characteristic. Higher scores are positively correlated with higher levels of anxiety.
Value reported by the patient on the Visual Analogue Pain Scale after surgery
The visual analogue scale (VAS) is commonly used as the outcome measure. It is usually presented as a 100-mm horizontal line on which the patient's pain intensity is represented by a point between the extremes of "no pain at all" and "worst pain imaginable."
