A lingually based triangular flap was used to remove the impacted third molar. An incision was made adjacent to the distal surface of the mandibular second molar and extended along the sulcus to the distobuccal corner of the mandibular second molar, an oblique vestibular incision was made and extended into the vestibular fornix of the mandible. Aligned with the mesiobuccal cusp of the second molar.

It was continued posterosuperior towards the anterior border of the mandibular ramus An incision will be made from the anterior border of the mandibular ramus to the distal surface of the mandibular second molar.

Pain was assessed through on a 10-point Visual Analogue Scale (VAS). (0-1= None, 2-4= Mild, 5-7= Moderate, 8-10= Severe)

For the objective evaluation of swelling, five distances were measured

• The distance from the mandibular angle to the lateral corner of the mouth
• The distance from the mandibular angle to the nasal alar curvature
• The distance from the mandibular angle to the lateral canthus of the eye
• The distance from the tragus to the soft tissue pogonion
• The distance from the tragus to the lateral corner f the mouth

Trismus was assessed by measuring the maximum inter-incisional opening (in millimeters) the distance between the incisal edge of the upper and lower central incisor using caliber.

The presence of alveolar osteitis (dry socket) will be determined clinically using BLUM'S criteria. Wound healing was assessed and recorded depending on the absence or presence of dehiscence, every opening along the incision will be recorded as dehiscence , dental tweezers will be used to identify it.
