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.

저자들은 1991년 10월부터 1992년 2월까지 본원 이비인후과를 통해 내원하였던 3명의 환자를 대상으로 경부식도 재건 목적으로 유리전완피판술 2례, 전흉부 축형피판슐 1례를 시행하였으며 다음과 같은 결과를 얻어 이에 문헌고찰과 함께 보고하는 바이다. 1. 유리 전완피판술을 이용하여 피판의 한쪽변을 deepithelization한 후 이중봉합 하였으며, 원위부는 완만한 S자 모양으로 도안하고 하부식도에 틈을 만들어 피판을 삽입함으로서 문제점으로 제기되어온 하부식도문합부 협착, 누공형성등의 합병증을 해결할 수 있었다. 2. 술전 방사선 치료로 수혜부의 혈관을 이용하지 못할때에는 전흉부 축형피판술을 사용하여 만족할 만한 결과를 얻을 수 있었다. 3. 공장 전이술의 합병중인 개복의 번거러움과 수술후 장폐색증, 운동장애, 연하곤란, 음식물의 역류동의 문제점을 해결할 수 있었다.

선천성 안검 결손증이 신생아에서 관찰 되었을 때에는 각막의 노출이 있는지를 확인하고 조기에 수술적 교정을 해주어야 한다. 그러나 본 증례같이 안검결손이 심하지 않는 성인의 경우 기능적 결함보다는 미용적인 목적으로 수술을 시행하게 된다. 본 저자들은 다른 기형을 동반하지 않고 안과적인 합병증이 없었던 선천성 안검결손 1례를 경험하여 결손 부위 표피제거와 양측 안검연피판을 이용하여 재건함으로서 미용 및 기능적으로 만족할만한 결과를 얻었기에 문헌고찰과 함께 보고하는 바이다.

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.
