Modification of the Conley incision for neck dissection.

OBJECTIVE: To describe a modified incision for neck dissection that makes the operation easier and provides good healing of the skin flaps and a cosmetic result in irradiated oral cancer patients. MATERIALS AND METHODS: Twenty-three oral cancer patients, treated previously with radiotherapy, developed metastatic disease in the neck requiring radical neck dissection. In 12 of these patients radical neck dissection was performed using conventional incisions such as: the Y incision (5 patients), classic Conley incision (6 patients), and McFee incision (1 patient). In the remaining 11 patients a modified Conley incision was used. This modified incision was compared with the conventional incisions using as criteria adequacy of surgical access, healing of the skin flaps, and the cosmetic result. RESULTS: In three of five patients (60%) treated with the Y incision there were complications involving early postoperative marginal necrosis of the skin flaps. The other 20 patients had normal healing and no necrosis or other complications were noted. CONCLUSION: According to our experience, we believe that the modified Conley incision in irradiated neck areas in oral cancer patients can be very useful because it is easy to perform and fulfills all the requirements for a radical neck dissection incision: adequate surgical access, good healing of skin flaps, and an acceptable cosmetic result.

Chronic idiopathic hyperphosphatasemia. Case report.

Chronic idiopathic hyperphosphatasemia, or juvenile Paget disease is a very rare syndrome that is characterized by fragile bones, bowing deformities, shortness of stature, large head, premature loss of teeth, radiographic evidence of expanded osteoporotic long bones with coarse trabeculations, and widened bones of the skull. Increased levels of serum alkaline phosphatase and increased levels of urinary total hydroxyproline are notable. We present a case of juvenile Paget disease that was associated with a history of precocious puberty. The patient had odontogenic osteomyelitis of the mandible that was treated by drainage, surgical debridement and antibiotic therapy.

Bony lid approach for apicoectomy of mandibular molars.

Apicoectomy in the lower molar region is indicated in many instances to avoid the need for prosthetic appliances. Nevertheless it is a method sometimes rejected by oral surgeons because of the thickness of the buccal compact bone in the lower molar area leading to extensive bone loss in addition to a restriction of vision and access during the operation. The present study reports twenty-four cases of apicoectomized mandibular molars treated with the bony lid approach which facilitates considerably the apicoectomy procedure. Once part of the buccal compact bone in the periapical area of the molars is removed, favourable conditions are created for the completion of the operation under direct vision of the operational field. The replacement of the buccal compact bone then minimizes the dimensions of the remaining bone cavity.

[Experiences from the use of Fibrinkleber in oral and maxillofacial surgery].

The combination of highly concentrated fibronogen, thrombin, clotting factor XIII and fibrinolytic inhibitor aprotinin, represents a new biological, haemostatic and adhesive system as "Fibrinkleber". Its way of action is the same as phase II of coagulation mechanism and its result is due to the formation of a strong and extensive fibrin clot. Because of the presence of aprotinin, that inhibits fibrinolysis, this clot remains for a longer period. A fast haemostasis and a maintenance of tissues in contact is attained and the healing becomes easier and accelerated. In addition, Fibrinkleber is completely resorbable and has very good tissue compatibility, contrary to synthetic adhesives. Regarding experimental results the fibrin adhesive system has been applied in 58 clinical cases with the indications: 1. convocation of fistulas introoral or extraoral 2. as biological band 3. extraoral fixation of skin grafts, used in areas with poor possibility of other kinds of skin fixation 4. in cases with clef lip and cleft palace 5. in combination with bioceramic materials 6. in combination with lyo-dura for reconstruction of orbita-floor fractures. We believe that the fibrinkleber cannot help a bad surgical technique nor replace a well made stitch of a wound. It is however possible to: 1. improve the surgical result (normal epithelization of the open intraoral wounds) 2. to shorten the duration of the surgery (dermatic grafts without any stitching) 3. accelerate the healing phases of a surgical wound 4. allow the modification of surgical techniques, when this is possible (convergence of fistulas etc).
