title: [Sensibility changes of the infraorbital nerve after primary surgery on patients with unilateral cleft lip according to J. Delaire].
abstract: OBJECTIVE
  The aim was to determine the overall sensibility changes in the area of the infraorbital nerve on patients with unilateral clefts lips and unilateral clefts lips and palate who had undergone primary surgical correction according to the principles of Delaire.
  
  
  METHODS
  Twenty patients (7-20years) with unilateral cleft lips (and palate) who had undergone surgery in infancy according to Delaire were included. Cutaneous sensibilities of the nasolabial fold and of the upper lip were tested using four cutaneous modalities. A tactil superficial sensibility light touch test, a two-point discrimination test (McKinnon-Dellon Disk-Criminator), and the determination of cold and warm detection thresholds (Quantitative Sensory Testing, Medoc Thermal Sensory Analyser). The possible difference of the sensibility between operated and controlateral sides of the face were compared. Results were finally compared to a control group of twenty healthy volunteers.
  
  
  RESULTS
  No significant difference could be found between the operated and non-operated side of the cleft group. There was also no difference between the cleft and the control group. Specific difference of perception between nasolabial fold and lip encountered in the literature were confirmed by the experiments.
  
  
  CONCLUSIONS
  The large subperiostal approach according to Delaire during the primary surgical procedure have not affected long term infraorbital sensibility of patients with unilateral complete cleft lip.
