The rehabilitation of the severely resorbed maxilla by simultaneous placement of autogenous bone grafts and implants: a 10-year evaluation.

The long-term success of Brånemark implants has been previously reported. The success rate of the same implants, when associated with autologous grafts, seemed much less predictable. In the present study it is demonstrated that when these implants are installed in conjunction with an autologous corticocancellous hip graft, either onlay or inlay, the cumulative success rate remains at 95% for individual implants in non-smokers. The short extracorporal time might be an explanation. On the other hand, the same approach in patients with congenital defects or who underwent radiotherapy is deceptive. The use of hyperbaric oxygen may dramatically improve these results.

Management of necrotizing fasciitis in the neck.

Necrotizing fasciitis is a soft tissue infection, usually polymicrobial, characterized by necrosis of fascia and subcutaneous tissue. Although it more commonly involves the groin, abdomen, and extremities, it may also occur in the head and neck. We report a case of cervical necrotizing fasciitis arising from a dental infection and review the cause, pathophysiology, diagnosis and treatment of this potentially lethal entity. Early detection and accurate intervention are emphasized. Extensive surgical debridement completed with hyperbaric oxygen therapy and antibiotics are the mainstay of treatment.

[The use of tongue flaps for oral tissue repair].

Pedicled tongue flaps have proven to be an effective method of repairing defects due to tissue loss in the oral cavity. Their rich vascular supply, mobility and close proximity to the lesion (lips, palate, floor of the mouth, cheek mucosa, oro- and hypopharynx) make the use of these flaps feasible in a variety of sites. After a review of the vascularity of the tongue, the possibilities of reconstruction will be discussed. The surgical procedure will be briefly documented with some clinical cases.

Melkersson Rosenthal syndrome. Review of the literature.

The M.R.S. is an uncommon condition of uncertain pathogenesis and course. The classic triad of signs includes recurrent orofacial oedema, recurrent facial nerve palsy and lingua plica. Patient histories, histologic findings, clinical findings and treatment were reviewed in the literature. A comparison with medicines reported in literature revealed a different result. A conservative treatment approach is recommended.

[The plunging ranula: a case report].

Plunging ranulas are rare. The diagnosis can be made by CT-scan or NMR and can be clinically confirmed by aspiration of saliva. It is now generally accepted that the best treatment exists of resection of the sublingual gland by intra-oral approach and drainage of the cyst content to the oral cavity. In an experimental set-up we treated a patient with ethoxysclerol with excellent result. However, after 6 months, swelling reappeared, followed by the classic therapy, as described above.

The value of cryotherapy in the management of trigeminal neuralgia.

Cryotherapy to 32 individual branches of the trigeminal nerve in 27 patients, who were followed up for 3 years, resulted in pain relief out-lasting return of sensation. After one year 65% of patients were pain free. In the treatment of trigeminal neuralgia, cryotherapy is an easy method with similar results but lower complication rate in comparison with other peripheral methods.

Myogenous or arthrogenous limitation of mouth opening: correlations between clinical findings, MRI, and clinical outcome.

The reproducibility and predictive power of MRI diagnosis was evaluated in a group of 70 patients with limited mouth opening. The predictive reliability of the MRI findings was assessed by comparing the images with a final clinical diagnosis that was based on the initial clinical diagnosis, adjusted and refined, when possible, by findings made during the treatment period (conservative treatment in 51 patients, conservative and surgical treatment in 19 patients). The overall reproducibility of the MRI interpretation by the radiologist appeared very good. The predictive reliability was excellent for normal disc position and fair for anterior disc displacement with reduction. For disc displacement without reduction, however, the predictive power was questioned because of false-positive MRI findings.

[Orthodontic treatment for orthognathic surgery: indications, possibilities and limitations].

The relation between the maxilla and the mandible can be so discordant that it cannot be corrected with orthodontic treatment only in adults, neither with orthodontic and jaw orthopedic in children. In these cases, only a combination of orthodontic treatment and orthognathic surgery can give the most satisfying results. A careful analysis of all patient records and an accurate planning of all the consecutive procedures should precede this treatment. Nowadays, computer-aided systems can provide substantial help in analysis and planning. In this article, possibilities and limitations of the orthodontic part of these treatments are elaborated.

[Complications of osteotomies].

The authors wish to present a review of the literature on complications in orthognathic surgery. They are classified into non-specific, general complications and into complications which are specific, according to the region the osteotomy is performed in. Though the list of possible complications is very extensive, one should realise that they are often based on single case-reports and that orthognathic surgery in general should be considered as a group of safe technical, surgical procedures.

[Oral lichen planus].

Oral lichen planus is a chronic inflammatory disease of adult onset. The etiopathology is based on a reaction against immunologically altered keratinocytes. There are variable forms of this condition, which at times make recognition difficult. Remissions are frequent. Associated oral carcinoma subsequent to the initial diagnosis of oral lichen planus is observed. Therefore all patients with oral lichen planus should be carefully evaluated and followed periodically.

Late loco-regional recurrences after radical resection for mandibular ameloblastoma.

5 cases of mandibular ameloblastoma are described with multiple recurrences after a long period of time. 4 of them were primarily treated by radical resection. 1 was initially treated by enucleation and extensive resection was performed only after its recurrence. The invasive growth of the recurrent tumor into the soft tissues and the cranial base, necessitating extensive ablative and reconstructive surgery, reflects the potential aggressiveness of this tumor. It is therefore recommended, to plan an adequate resection in cases of multicystic ameloblastoma, which includes a margin of at least 1 cm, of apparently non-invaded bone. If the tumor has eroded through the cortical bone and invaded into the soft tissues, wider margins are necessary to eliminate possible tumor extensions that are left behind. Adequate follow-up on a regular basis should enable the clinician to detect early recurrence so as to avoid major surgery.

Sicca syndrome with iron deposition in the salivary glands.

A case of iron deposition in the labial accessory salivary glands associated with prominent xerostomy and xerophtalmy is reported. Suffering from a myelodysplastic syndrome with refractory anaemia, this patient received multiple transfusions over the past 7 years. A transfusional haemosiderosis gradually developed. Histopathologic examination of accessory salivary glands demonstrated haemosiderin deposition in the serous alveoli and in the epithelial cells of intercalated and interlobular ducts. A relationship between the iron deposition in the salivary glands and the development of the sicca syndrome is suggested. The literature related to iron deposition in salivary glands and sicca syndrome is reviewed.

The use of costochondral grafts in arthroplasty of the temporomandibular joint.

Replacement of the condyle with a costochondral graft restores the altered biomechanics after condylectomy or gap-arthroplasty procedures. It avoids the recurrence of ankylosis. In the child, this graft allows harmonious growth of the mandible due to the characteristics of the costochondral cartilage. A case of uncontrolled multidirectional and excessive growth of the graft during pregnancy supports the view that the costochondral junction also carries intrinsic growth properties. Long-term follow-up evaluation shows very satisfactory cosmetic and functional results. In patients neglecting postoperative jaw mobilisation, maximal interincisal opening is acceptable but remains low. If no posterior dental support is provided after restoring the vertical dimension with the graft, some degree of graft resorption is possible.
