Effect Of Preoperative Anxiety On Healing Recovery After Oral Surgery
Objectives: There has been few research assessing correlation between patient’s psychology and wound healing after oral surgery although stress plays a key role in recovery process. The objective of this study was to determine the relationship between anxiety immediately before impacted third molar (ITM) surgery and postoperative complications, including swelling and trismus.
Methods: This prospective study involved 64 patients requiring ITM surgery from March 2016 through June 2016. All treatments were conducted with the same surgical protocol by 2 surgeons from Department of Oral Surgery. The Vietnamese version of State-Trait Anxiety Inventory (STAI) and Dental Fear Survey (DFS) was employed to assess general and dental anxiety, respectively. At the screening day, researcher collected demographic features, Pederson classification, and score of trait part of STAI. Moreover, the baseline diagrams of facial dimension and mouth opening were measured. On the surgery day, state part of STAI (STAI-S) and DFS were fulfilled before treatment. At 48-hours after surgery, all participants returned to have evaluation of swelling and trismus development with the same anatomy landmarks. Correlations of items including demographic features, Pederson classification, duration length and psychological indices with development of swelling and trismus were statistically analyzed using Spearman’s rank-order correlation test. Then, the items which demonstrated p>0.25 were used as explanatory variables in following multiple linear regression analysis, whereas development of swelling and trismus were used as objective variables.
Results: The linear regression analysis revealed significant relationships between STAI-S score with swelling level (B=0.138, R2=0.122) and trismus (B=-2.544, R2=0.089) at 48-hours after surgery (p<0.05). On the other hand, DFS only related with trismus (B=-1.933, R2=0.087), but not swelling level (p>0.05).
Conclusions: State anxiety assessed by STAI-S had considerable relationship with the clinical severity of swelling and trismus during healing period. From a practical perspective, patient’s stress affects on recovery process stronger even than surgical difficulty and duration length.
