We describe the procedure for reconstruction of a defect on the buccal mucosa and the prolabium with a buccal mucosal transposition flap and an artificial dermis graft. The preparation of the flap started with an incision extending from the border of the defect to the corner of the mouth. The pivot point of the flap was near the stump of the excised prolabium. Only the buccal mucosa was elevated from the buccal surface. It was transposed onto the defect of the prolabium and sutured to the edges of the defect. After reconstruction of the prolabium, the artificial dermis was trimmed and sutured to the mucosal and skin edges of the surgical defect. This is an easy and minimally invasive procedure to cover a defect of the buccal mucosa and the prolabium. In our experience, the wound healed with good, functional, and cosmetic results.

We describe a procedure of oral tumor resection and salivary duct relocation with an ultrasonic surgical aspirator. After mucosal incision, resection of the underlying musculature was performed using an ultrasonic surgical aspirator. Using the apparatus, the salivary duct was easily exposed without damaging or cutting the duct. After identification of the salivary duct, salivary duct relocation was performed. After resection of the tumor, the artificial dermis was trimmed and sutured to the mucosal edges of the surgical defect. This method is a reliable and simple procedure that can be used to avoid postoperative complications such as salivary fistula or swelling of the gland.

We describe here 3 minimally invasive procedures for removing lesions from the maxillary sinus using an ultrathin endoscope, microscope, and otoscope.Preoperatively, a lesion in the maxillary sinus was identified by radiographic examination. Then the access hole position and advance direction of the endoscope and forceps were planned. Under local anesthesia, a small incision on the buccal mucosa was made in the planned position. The anterior bony wall of the sinus was exposed subperiosteally, and a small access hole for the insertion of an endoscope was made in the planned position and angled with a fissure bur. After identification of the lesion endoscopically, microscopically, or otoscopically, a forceps was inserted into the sinus cavity through the hole, and the lesion was seized and withdrawn from the sinus.The surgical procedures are suggested to be reliable, easy, and minimally invasive that provide a limited incision and bone removal and respect the integrity of the sinus.
