Prosthetic therapy for sleep apnea syndrome.

Twenty patients with sleep apnea syndrome were examined polysomnographically with and without an Esmarch sleep apnea appliance. The relationship between the therapeutic effect of the device and dentofacial morphologic characteristics of the patients were analyzed with the use of diagnostic casts and cephalometric radiographs. The apnea index or number of apneic episodes per hour decreased significantly (p < 0.0001) after insertion of the appliance. The diagnostic casts and cephalometric analyses revealed that the device was most effective for patients who exhibit a tendency toward micrognathia (p < 0.03) and a short soft palate (p < 0.01). The Esmarch appliance is indicated for the treatment or diagnosis of sleep apnea syndrome.

Total maxillary osteotomy for cleft palate rehabilitation.

The Obwegeser/Perko modification of the high horizontal osteotomy for management of mature cleft palate/cleft lip patients is described in detail. Careful evaluation and treatment planning preoperatively are stressed. Three cases which emphasize the need for individual tailoring of the maxillary procedure are presented. Results were found to be uniformly good, with few complications. In that the skeletal deformity of maxillary micrognathia/retrognathia is readily corrected by high horizontal osteotomy, this procedure is an ideal modality for the late rehabilitation of the patient with a cleft palate.

The retrognathic mandible--surgical correction.

The preceding case reports demonstrate the excellent results available to the patient with a retrognathic mandible. Etiology, adverse effects, and the modalities used in evaluation of the underdeveloped mandible have been discussed. The age at which surgical intervention is undertaken needs additional input by clinicians. Several surgical procedures have been and are employed to advance the mandible. The C osteotomy is recommended since the final result has been excellent and consistent. The surgeon has constant surgical control and vision. The advanced portion of the mandible can be firmly held by intraosseous wires. There is minimak disturbance of muscle position and the inferior alveolar nerve. We have not encountered unusual loss of blood, immediate postoperative problems with the airway, infection, or unfavorable relapse. A postoperative regimen that has been found rewarding is discussed. We have come to the conclusion that most patients can tolerate lengthy surgical procedures with few adverse side effects. Our colleagues in anesthesia and nursing provide superb operative and postoperative care. When the preoperative work-up indicates that more than one procedure is indicated, we recommend that the total surgical treatment plan be carried through at one operation, although occasionally this approach may be contraindicated. We should strive for perfection and can fall short of this goal when a patient will not return for additional surgical procedures which could have been accomplished during the first operation. Although good results have been experienced with both the C osteotomy and the sagittal split osteotomy, we believe that the C osteotomy is a superior procedure. However, this does not imply that the sagittal split osteotomy should not be a part of the armamentarium of the oral surgeon. In conclusion, the C osteotomy, the sagittal split osteotomy, genioplasty, and additional procedures--such as a mandibular alveolar osteotomy to intrude supraerupted teeth--when indicated, can provide very favorable results in cases of retrognathia or micrognathia of the mandible.

Radiographic observations of pyknodysostosis. Report of a case.

A case of pyknodysostosis in a 32-year-old woman has been reported. The patient presented typical skeletal changes, separated cranial sutures, open fontanelles, partial aplasia of the terminal phalanges of the fingers and toes, and brachyphalanges. The oral findings included lesions resembling periapical cementoma, hypoplasia of the maxilla and mandible, crowding of teeth, and a median raphe.

Oromandibular-limb hypogenesis syndrome: type II C, hypoglossia-hypodactylomelia.

A patient with oromandibular-limb syndrome, Type II C, hypoglossia-hypodactylomelia, is documented and the pertinent literature critically reviewed. In addition to limb and tongue anomalies the patient had hypognathia, microstomia, absent mandicular permanent incisors, and enamel dysplasia. Her unrelated parents and siblings are normal. Past medical history for drug exposure to the mother during pregnancy was negative.

Dental root agenesis secondary to irradiation therapy in a case of rhabdomyosarcoma of the middle ear.

There have been only a few published reports on the dental-facial effects of radiation therapy and the subsequent oral management of these patients. A case involving a 13-year-old black male patient with a history of rhabdomyosarcoma is presented. The patient received 4,050 rads of radiation to the right middle ear when he was 2 years of age. His residual medical and dental difficulties are apparently complications from the initial therapy. Examination of the oral cavity revealed bimaxillary micrognathia and marked loss of vertical dimension. A Class II facial profile with Class I molar relationship was observed. The mandible was thin and hypoplastic, with a small knife-edge alveolar ridge. The remaining eighteen erupted permanent teeth were very mobile, and root development had ceased after only initial formation. All of the teeth except the first permanent molars were extracted, and immediate partial dentures were inserted at the time of surgery. A discussion of therapeutic considerations follows the case report.

Two ways to correct bird-face deformity.

Two different ways of correcting micromandibularism inherent in the bird-face deformity have been described. Both procedures may be applied to correct the symmetric or the asymmetric types of bird-face deformity. Both have the elongation in the front area by means of one- or two-step advancement genioplasty in common. The difference between the two procedures lies mainly in the way the elongation of the mandibular body is achieved. Procedure 2 advocates the elongation of the mandible by means of vertical osteotomy within the tooth-bearing area, and procedure 1 advocates the elongation of the mandible behind the tooth-bearing area by means of the extended sagittal split osteotomy. Both procedures are demonstrated by drawings and by cases of patients who have been operated on.

Cleft palate lateral synechia syndrome. Review of the literature and case report.

Cleft palate lateral synechiae syndrome is a rare syndrome consisting of cord-like interalveolar adhesions and concomitant hypoplasia of the mandible. We have presented an infant with CPLS syndrome and coincident hydrocephalus. Surgical division of the adhesions is necessary to allow normal feeding, avoid upper airway obstruction, and allow normal mandibular function and growth.

Hypodontia, impacted permanent teeth, spinal defects, and cardiomegaly in a previously diagnosed case of the Yunis-Varon syndrome.

The Yunis-Varon syndrome is a rare hereditary disorder with ectodermal and skeletal anomalies that include agenesis or hypoplasia of the clavicles, craniofacial disproportion with severe micrognathia, digital anomalies, prenatal and postnatal growth deficiency, and neonatal death. Only 12 cases have been reported in the literature. Although neonatal death is a significant feature of this syndrome, two case reports describe children, both males, who were 30 months and 3 years of age at the time of investigation. The 30-month-old child was reexamined at 11 years of age, and had further clinical and radiologic features that included hypodontia, impacted permanent teeth, spinal defects, cardiomegaly, bilateral hearing loss, and metatarsus adductus. Children who survive the neonatal period and continue to thrive with many of the features of the Yunis-Varon syndrome as well as the new features described in this article may not have a distinct yet related syndrome.
