Objective: To evaluate the results and clinical characteristics of free palatal mucosa flap in reconstructing peri-implant attached soft tissue.
Methods: 126 cases with partial edentulous or edentulous were undergone soft tissue reconstruction and implant treatment from July 1997 to June 2005. A total of 388 implants were placed. The mean follow-up period was over 13 months. Mucosa flaps were measured at the operation and compared the size changes one year after operation.
Results: Necrosis occurred in 3 mucosa flaps out of 126 cases 10 days postoperatively. Mean shrinkage of mucosa flap was 56%(37%-70%). No loss of implant was found in the last follow-up and attached soft tissue width was over 3 mm in 371 implants. Eight implants were diagnosed as peri-implantitis (2.06%).
Conclusion: It is effective and predictable to reconstruct peri-implant attached soft tissue with free palatal mucosa flap.

A 61-year-old woman underwent an emergent operation with sigmoid colon cancer resection, colostomy, and ileostomy on colon perforation. The low ileostoma, caused by intra-abdominal bad conditions, had irritated the surrounding skin after surgery, intermittently forcing the patient to fast for a certain period. Six months after the operation, under the judgment that re-ileostomy, essential for hospital discharge, seemed very difficult through another laparotomy, we attempted to make the ileostoma higher not with pulling the ileum from the abdomen but with lowering the surrounding skin using skin flap formation techniques.

Objectives: To address controversies regarding target volume delineation for adjuvant intensity-modulated radiation therapy for oral cavity squamous cell carcinoma with pedicled flap reconstruction and elective nodal irradiation (ENI).
Materials And Methods: During target volume delineation, the primary tumor bed was the pre-surgical gross tumor volume with an additional isotropic margin of 5-10 mm. Additionally, the flap and body tissue junction were given a margin of 5-10 mm (if not already given).

Background: This systematic review and meta-analysis aimed to assess the efficacy of autologous platelet concentrate (APCs) in comparison with coronally-advanced flap alone or in combination with connective tissue graft or other biomaterials or bioactive agents for root coverage (RC) of Miller's Class I and II gingival recession defects by measuring the keratinized mucosa width (KMW).
Materials And Methods: This systematic review and meta-analysis was conducted in accordance with the preferred reporting items for systematic reviews and meta-analysis guidelines. An electronic search of the literature was conducted in PubMed, EMBASE, Scopus, Cochrane, Web of Science, Magiran, Scientific Information Database, and Irandoc for randomized clinical trials (RCTs) that used APCs for RC in their intervention group.

To explore the application of modified Von Langenbeck cleft palate repair with tension-free mucoperiosteal flap near the nasal cavity and without relaxation incision, and the cleft palate defect was repaired by covering both sides of the edge of the in situ mucoperiosteal flap. This treatment method provides a good aesthetic restoration effect. Modified Von Langenbeck cleft palate repair with mucoperiosteal flap near the nasal cavity without tension and relaxation incision was used to repair the cleft palate.
