[Chronic desquamative gingivitis syndrome: retrospective analysis of 33 cases].

OBJECTIVE: Desquamative gingivitis is a chronic diffuse inflammation of the gingiva. The aim of this study was to determine the causes and the clinical characteristics of desquamative gingivitis. PATIENTS AND METHODS: This was a retrospective descriptive study including 33 consecutive patients (25 women and 8 men) seen at a dermatology clinic for erosive gingivitis. RESULTS: Thirteen patients (39 p. 100) had cicatricial pemphigoid, 12 (36 p. 100) had lichen planus, and 5 (15 p. 100) had pemphigus. Delay to diagnosis was a mean 19 months. The pinch sign was positive in 12 of the 13 cases of cicatricial pemphigoid. Dapsone improved the buccal lesions of cicatricial pemphigoid in all cases. Systemic corticosteroid therapy and acitretine were the most effective treatments for lichen planus and corticosteroid therapy improved pemphigus in all cases. At the time of assessment, only 3 cases of cicatricial pemphigoid, 2 cases of lichen planus and 1 case of pemphigus had reached complete remission without treatment. DISCUSSION: Cicatricial pemphigoid and lichen planus are the most frequent causes of desquamative gingivitis, accounting for three-quarters of the cases. Positive diagnosis may be difficult and may require sophisticated techniques to avoid delay. Despite the effectiveness of symptomatic treatment, desquamative gingivitis may have a long course.

[Osseous leiomyosarcoma of the mandible. Case report and review of the literature].

Primary leiomyosarcoma localized in the mandibular bone is exceptional. We report a case with active intraosseous development and review eight other cases in the literature. The clinical signs at discovery were nonspecific. Radiological imaging showed osteolysis with no periosteal reaction. MRI was required to study extension to soft tissues and was useful for guiding wide excision. The risk is dominated by distant metastasis rather than locoregional extension. The histological diagnosis is difficult and requires an immunohistochemistry study. No therapeutic consensus has been established.

[Dental agenesis. Results of a prospective study of 30 cases].

OBJECTIVE: We conducted a prospective study to determine the types of bone anomalies observed in different types of dental agenesia. PATIENTS AND METHOD: This prospective series included 30 patients who attended our pluridisciplinary clinic since 1988. There were 22 cases of non syndromal agenesia and 8 cases of syndromal agenesia. Patients consulted for a variety of reasons, no specific sign was found. The diagnosis was based on the panoramic x-ray and confirmed at the genetic consultation. RESULTS: Results were systemized by localization of the agenesia. In all cases, the height of the bone crest was preserved compared with the adjacent teeth. In the anterior part of the maxillary, the bone crest was thin showing a water drop aspect. In the posterior maxillary, there was a decrease in the subsinusal height due to invagination of the floor of the sinus. In the anterior part of the mandible, the crest had a knife blade aspect but no loss of height and in the posterior part, a preserved distance between the residual crest rim and the dental canal. DISCUSSION: In 60% of the solitary agenesias in the anterior part of the maxillary, augmentation was not required. A sinus graft was required in all cases involving the posterior maxillary. Multiple anterior or lateral agenesias were treated with a parietal graft.

[Pre-implantation iliac graft in the sinus. Retrospective study of the complications encountered in 100 cases].

MATERIAL AND METHODS: This series included 60 patients operated on between 1996 and 1998. Preoperative work-up included a x-ray study bone quality, preparation of the buccal cavity and assessment of the rhinosinus. We used the surgical technique described by Boynes and Tatum with modifications. The bone graft, mean 16 cm2 was fixed with a stud and clamp assemble or a long screw through the gingival crest, or with a microscrew on the lateral wall of the maxillary sinus. Minimal follow-up was two years. RESULTS: Mean age was 54 years (range 20-80). There were only two minor (hematoma) donor site problems. At the receiver site, there were 30 perforations of the mucosa that had no effect on the graft vitality. During the postoperative period, there were 2 hematomas that resolved spontaneously and 20 cases of dysesthesia in the V2 territory. Mid-term outcome (15 days to 6 months postoperatively) showed: 4 graft infections requiring removal in 3 cases and 6 partial resorptions requiring a new parietal bone graft in 3 cases. DISCUSSION: The iliac bone graft provided abundant cancellous tissue. The mid-term outcome was satisfactory although the postoperative problems resolved more slowly and were more painful than when harvesting a parietal graft. Mucosal perforations were frequent but reparable and did not increase postoperative morbidity. Infection was the most severe complication. Our incidence (3%) was slightly higher than reported in the literature. A possible explanation would be the mean height of the graft (18-20 mm) and the severity of the atrophies treated.

Serratus anterior free fascial flap for dorsal hand coverage.

Reconstruction of the dorsal surface of hand defects requires thin, pliable, well-vascularized tissue with a gliding surface for the extensor tendon course. Fasciocutaneous or fascial flaps are the two surgical options. Fascial flaps present the advantages of thinness and low donor site morbidity. The authors present 4 cases of serratus anterior free fascial flap (SAFFF) used to cover the dorsum of the hand. The SAFFF with skin graft has many advantages for a fascial flap: long, constant vascular pedicle; very thin, well-vascularized tissue; low donor site morbidity; and the possibility of simultaneous donor and recipient site dissection. Furthermore, it can be associated with other flaps of the subscapular system for complex reconstructions. Of the 4 observations described, 2 used associated flaps, 1 used the SAFFF with a latissimus dorsi flap, and 1 used a scapular bone flap with the SAFFF. One flap was lost due to an electrical lesion to the forearm vessels.

[Serratus anterior muscle flap: indications and sequelae. 26 cases and review of the literature].

The authors report their experience of the use of the serratus anterior flap. Between 1992 and 1997, this flap was used for 14 head and neck and 11 limb and 1 intra-thoracic reconstructions. Twelve patients were examined for functional evaluation of the donor site. When only 2 or 3 slips are raised donor site morbidity is limited to moderate winging of the scapula with no functional disorders. Because of its thinness, and the length and diameter of the vascular pedicle, the serratus anterior flap is our favourite option for small wounds of the distal limb or composite and large defects in association with flaps of the subscapular system.

[A new application of extraoral implants: the permanent percutaneous electrical connection. Apropos a case].

The principle of EOI is an implant fixed to the bone supporting a percutaneous abutment. Placed through the skin, the abutment allows a permanent communication between inside and outside of the organism. A rigorous very precise surgical protocol has allowed good results of the technique for over 20 years and shown the reliability of this two-piece device. This surgical protocol and device concept have been used by the authors to design a percutaneous electrical connector experimented in a rabbit model since 1996. A percutaneous electrical connector called PEP (percutaneous electrical plug) directly steming from the Sweden and German extra oral implants as been design for human applications. Authors describe the surgical placement and loading of there first PEP, under Huriet law, in an otologic application: the treatment of sever, drug-resistant tinnitus by electrical stimulation of the internal ear. The anatomical implantation area of these new extra-oral implants is retro-auricular. So the implants placements should be realized by ENT and maxillo-facial surgeons.

[The facial artery-buccinator musculo-mucosal flap for reconstruction of the palate].

Since may 1999, 5 facial artery musculo-mucosal (FAMM) flaps have been used for mucosal reconstruction of the top of the mouth. The FAMM flap, first described by Pribaz in 1993 is a modification of the naso-labial cutaneous flap. The flap can be inferiorly based on the facial vessels (orthograde flow) or superiorly based (retrograde flow). It can easily reconstruct palate, alveolus and soft palate defects. The are of rotation has its pivot point inferiorly at the retromolar trigone, superiorly at the gingival labial sulcus. The FAMM flap has been used for 2 palatal fistula after facial blast injuries and 1 secondary cleft palate surgery. For the cleft palate surgery an Lefort 1 osteotomy with iliac crest graft was associated. All the flap but one survive with primary healing. One partial necrosis was noted but spontaneously healed secondarily. The FAMM flap is a reliable flap for mucosal reconstructions of the top of the mouth. The flap dissection is easy and the donor site morbidity is low.

[Congenital stenosis of the piriform aperture: a cause of respiratory distress in newborn infants. Review of the literature, from 2 cases].

Congenital nasal pyriform aperture stenosis is a rare cause of neonatal airway obstruction. Computed tomography confirms the diagnosis and delineates the anomaly. This abnormality can be isolated or associated with abnormalities of the midface. The two options are surgical or medical treatment. The surgical treatment usually used is a surgical enlargement of the nasal pyriform aperture via a sublabial approach. We report 2 cases of congenital nasal stenosis treated successfully by an inter-maxillary disjunction followed by an expandable palatal plate. This simple and low morbidity technique allowed a durable transversal augmentation of the pyriform apertures.

[Microvascular mandibular reconstruction and implantology. A study of the stability of long-term results, apropos of 2 cases followed for 8 years].

The objective of this study was to determine the long term stability of implants on mandibles reconstructed by microvascular bone transfer. We present two cases of mandible reconstruction, the first one was performed after tumor resection and the second one after gunshot injury. The reconstructions were performed by iliac crest osseous and osteocutaneous free flaps and the mean follow-up period was 8 years. The implant was an IMZ Titanium and a classic prosthetic system was used. No complication was observed (mucous ulceration, infiltration around the implant), and the feared friction phenomenon between the neo mucosa and the reconstructed bone has not been a problem for long term follow-up.

[MALT lymphoma with parotid and gastric involvement during Gougerot-Sjögren syndrome].

Sjören syndrome favors the development of lymphoma, particularly in the salivary glands with MALT lymphomas. The differential diagnosis with benign lymphoepithelial sialadenitis can be difficult. A 78-year-old woman had an oculo-buccal sicca syndrome for 10 years and developed parotid hypertrophy. The first biopsy, performed 7 years before the present investigation had showed chronic lymphoepithelial sialadenitis. A second biopsy showed MALT lymphoma. Search for extension revealed a second gastric localization of the lymphoma. This patient had a particular immunophenotype, showing a CD5+ tumoral population frequently observed in mantel lymphomas and usually lacking in MALT lymphomas. Recently, however, another case similar to our own, has been reported in the literature. The observations raise the problem of distinguishing between mantel lymphoma and MALT lymphoma.

Reverse first dorsal metatarsal artery adipofascial flap.

An adipofascial flap distally based on the first dorsal metatarsal artery is described. This flap was used successfully in three cases with skin defects of the distal foot. The advantages of this flap are minimal donor site morbidity and its applicability for larger defects. The surgical technique is described, and indications, advantages, and disadvantages of the method are discussed and compared with the distally based first dorsal metatarsal artery fasciocutaneous flap. The reverse first dorsal metatarsal artery adipofascial flap offers a new solution for reconstruction of distal foot defects.
