foreign body in the floor of the mouth

A case of unusual presentation of foreign body in the floor of mouth is reported. The patient presented with a history and clinical findings of sublingual ranula. Marsupialisation and sublingual sialadenectomy was planned. After marsupialisation, a foreign body [spray cover] was found between the lumen of the submandibular duct and the ranula

Adjustable mandibular advancement prostheses versus distraction osteogenesis for treatment of obstructive sleep apnea in patients with mandibular retrognathia

The objective of this prospective study was to compare the efficacy of mandibular advancement porstheses to mandibular distraction osteogenesis in retrognathic patients with obstructive sleep apnea [OSA]. Twelve patients with mandibular retrognathia and confirmed OSA were studied. The participated patients were equally divided into two groups, those who were scheduled for surgical correction of the retrognathia through distraction osteogenesis [group I] and those who were treated with custom made mandibular advancement prostheses [group II]. Lateral cephalometric tracings and polysomnographic data were utilized to compare the efficacy between the two different modalities of treatment. Based on the limited number of patients, the results of this study suggest that both mandibular advancement prostheses and distraction osteogenesis are useful alternatives when indicated in treatment of OSA

Implant retained maxillary obturators in treatment of resected maxilla

The purpose of this study was to evaluate the clinical results of maxillary obturators retained by both natural teeth and standard endosseous implants placed in the zygomatic bone following the surgical ablation of maxillary tumors. Six patients with maxillary tumors were studied. All patients underwent hemi or partial maxillary resection. Two standard endosseous implants were placed at the ipsilateral zygoma simultaneously at time of surgical resection. Definitive maxillary obturator was fabricated after a healing period of six months and retained in the defect side by ball attachments to the standard endosseous implants. Masticatory efficiency, biting force, speech function with the definitive obturators as well as the survival rate of the standard endosseous implants were evaluated. The results of this study suggest that maxillary obturators retained with a combination of natural teeth at the non-defect side and endosseous implants placed within the defect can be used to reliably reconstruct patients after ablative resection of the maxilla
