Tongue reconstruction after oncologic resection with free flap is important to conserve function and shape. Vertical rectus myocutaneous free flap is usually used for total tongue reconstruction, but our patient was thin and primary closure after flap elevation seemed hard. So we used anterolateral thigh free flap to reduce donor site morbidity and to maintain bulk of the tongue as much as possible. Deepithelization of both middle side of flap and folding was done to mimic normal tongue base's shape and volume. Flap survived without complication and patient underwent concurrent chemoradiation therapy three weeks after surgery. Anterolateral thigh free flap can be good candidate for total tongue reconstruction especially in thin patient.

Microvascular tissue transfers have facilitated primary closure of various complex defects after radical ablation of head and neck cancers. From Oct 1991 to Feb 1992, we used forearm free flap in two patients and delto-pectoral flap in one patient who had preoperative irradiation for pharyngoesophageal reconstruction. The stricture and fistular formation were most troublesome complication in forearm free flap, so we designed as lazy S shape in distal flap margin to prevent circular contraction and longitudinal margin was deepithelized(5mm) and sutured double layer to withstand fistular formation and this can be considered useful in place of a free jejunal transfer.

Purpose: Congenital upper eyelid defect is rare anomaly whether it is compared with syndromic anomaly or not. It has many clinical manifestation in the extent, location. Many operation procedures such as simple closure, semicircular rotation flap, Cutler Beard procedure, lower lid rotation flap, etc can be used to reconstruct eyelid defects. We intend to introduce a simple, congenital eyelid defect which was not compared with syndromical anomaly, ophthalmic complication. Methods: Our experience is a case of 19 years old female who had a upper eyelid coloboma without any other anomalies. we could not find any skeletal deformity in orbital CT scan. she had no ophthalmic problem. we reconstructed the defect with bilateral marginal flap after deepithelization of supramarginal area and tarsal reposition. Results: There were no visible deformity of lid lining. postoperative scar was favorable. satisfactory results were obtained in cosmetic and functional aspects. Conclusion: Upper lid coloboma without other anomalies is rare. we obtained satisfactory outcome as treated this rare case with marginal flap advancement.

The purpose of this study was to evaluate whether removal of gingival epithelium with pulsed Nd :YAG laser could inhibit the downgrowth of junctional epithelium after alloplastic material grafting in periodontal bone defect. The periodontal bone defects were created surgically on the palatal aspect of the upper right and left molar teeth in 30 rats and filled with resorbable calcium carbonate($Biocoral\;450^{(R)}$: Inoteb, France). The control sites(right molar area) was sutured. The test side (left molar area) received controlled deepithelization of the oral and sulcular epithelium with pulsed Nd:YAG laser($Sunrise\;Maste^{(R)}$: Sunrise Technologies, U.S.A.) under the mode of 1.75W, 15Hz, 116mJ/pulse and was sutured. The control and test sites were evaluated clinically and histologically, at 1, 3, 7, 14, and 28 days postoperation. Clinically, the gingiva showed normal color and shape at the 5th day in the control site and at the 10th day in the test sites. Histologically, the junctional epithelium was formed at the 7th day in the control sites and at the 14th day in the test sites, and the long JE attachment were observed at the 28th day in both sites. The attachment of connective tissue to root surface was observed initially at the 7th day in the control sites and at the 14th day in the test sites, and completed at the 28th day in both sites. In summary, these results showed that the removal of oral epithelium using pulsed Nd:YAG Laser could not prevent epithelial downgrowth after alloplastic material implantation in rat periodontal bone defect.

Purpose: Pilonidal sinus is a frequent disease that occurs mostly in hairy young men, defined as chronic inflammation and infection of the postsacral sinuses. Wide excision of the affected area is the treatment of choice. Many techniques have been described to cover the defect. However none appears to be the ideal procedure to prevent infection, recurrence, and delayed wound healing. We present the results of an alternative technique that we performed by using partial deepithelized gluteal transposition flap for reconstruction of the defect following wide excision. Methods: From October 2004 to September 2007, we performed the partial deepithelized gluteal transposition flap method on 6 patients. We modified the transposition flap techniques by deepithelialising the medial parts of the flap and burying them under the opposing edge of the flap. The results were compared with previous studies and evaluated regarding duration of surgery, size of defect, hospitalization periods, and complications. Results: All the flaps were healed well with no partial or complete loss of the flap. Hospitalization and immobilization periods were acceptably shortened. Recurrence was not seen. The aesthetic outcome was also satisfactory and all patients were satisfied with the results. Conclusion: The main advantage of our techniques is using healthy tissues to obliterate the dead space, to provide an extra-cushion, and to prevent deep dehiscence. We believe that the partial deepithelized gluteal transposition flap is a good alternative method for treatment of pilonidal sinus.

Purpose: The purpose of this study was to evaluate the clinical effectiveness of and patient's satisfaction with treatment of gingival melanin hyperpigmentation with a Nd:YAG laser and a high speed rotary instrument. Methods: Three patients with melanin hyperpigmentation in the anterior parts of the gingiva were chosen for this case study. Clinical photographs were taken at the preoperative state and three patients were treated under local anesthesia. In the maxilla, the gingival deepithelization was conducted with a high speed diamond bur, whereas, in the mandible with a Nd:YAG laser. Clinical photographs were taken immediately after the procedures and at the 1st, 2nd, and 4th week to evaluate clinical color changes. A week after the procedure, the patients filled out a questionnaire about any pain or discomfort. At the 4th week after the procedure, the patients filled out questionnaires about esthetic aspects of the results of treatment. Results: In all cases, both anterior gingival areas were depigmented with satisfaction and the patients did not complain of severe pain or discomfort. At the 1st week of healing, the gingiva showed moderate to fast epithelization. Two weeks after the procedure, clinically, the gingiva showed almost complete healing. Four weeks after the procedure, there was significant improvement in gingival melanin hyperpigmentation. Conclusions: The Nd:YAG laser and the high speed rotary instruments seem to be effective for the esthetic treatment of gingival melanin hyperpigmentation.
