Impacted supernumerary tooth developed under palatal polyp.
We present a rare case of an infant's palatal polyp associated with an impacted supernumerary tooth. We have previously reported three cases of palatal polyps in infants [1]. In one case, after surgical removal of the palatal polyp at the age of 1 year and 8 months, the lesion subsequently began swelling. A periapical radiograph at the age of 2 years and 9 months revealed a small calcified mass in the maxillary left incisor region. The swelling was kept under observation, the calcified mass developed gradually and was removed surgically at the age of 5 years and 5 months. The removed calcified mass was clinically diagnosed as an impacted supernumerary tooth and this was confirmed histologically. Histological findings did not indicate any relationship between the palatal polyp and the impacted supernumerary tooth.

Characterization of maxillofacial soft tissue vascular anomalies by ultrasound and color Doppler imaging: an adjuvant to computed tomography and magnetic resonance imaging.
PURPOSE: The special imaging and physical properties of ultrasound and color Doppler offer opportunity for continued investigation in oral and maxillofacial surgery. This study prospectively investigated ultrasound and color Doppler in addition to computed tomography (CT) and magnetic resonance imaging (MRI) in the characterization of several vascular or suspected vascular anomalies and assesses the value of ultrasound and color Doppler in their diagnoses. PATIENTS AND METHODS: Six patients with vascular or suspected vascular anomalies seen between 1997 and 1999 composed the study group. All patients were clinically evaluated, imaged by CT with contrast and/or MRI with contrast, ultrasound, and Doppler (including color, spectral, and power). Ultrasound studies were performed in the presence of the referring oral and maxillofacial surgeons to provide consultation on anatomy and differential diagnosis as well as to witness the dynamic study. Three patients were further studied by angiography. The Mulliken/Glowacki classification (Plast Reconstr Surg 69:412, 1982) and designations and the Jackson et al modification (Plast Reconstr Surg 91:1216, 1993) are used in this study. RESULTS: A spectrum of lesions emerged in this small case series. Detailed clinical and imaging findings and a summary of diagnostic impressions allowed general and specific observations and permitted assessment of the value of ultrasound and color Doppler in the diagnosis of these lesions. The diagnostic accuracy of ultrasound and Doppler was equal to or better than that of CT and/or MRI in 4 of 6 cases. In the other 2 cases ultrasound did not specifically diagnose the lesions but did allow assessment of vascularity. In one of these cases the correct diagnosis was made by a combination of CT and angiography, and in the other the diagnosis was made by nonenhanced MRI. An ancillary study showed that the combination of nonenhanced MRI with ultrasound and Doppler provides more information than contrast-enhanced MRI alone and is more cost effective. CONCLUSIONS: 1) A single imaging modality is frequently unable to provide sufficient diagnostic information to allow confident clinical management of a vascular malformation. 2) A team approach and conferencing between imaging specialists and clinicians promote better diagnosis and management. 3) Nonenhanced MRI with ultrasound/color Doppler can be substituted for enhanced MRI to provide the best diagnostic information and at reduced cost. 4) Ultrasound/color Doppler is an important adjuvant to CT and MRI in the diagnosis of vascular or suspected vascular anomalies.
Development of squamous cell carcinoma from pre-existent oral leukoplakia: with respect to treatment modality.
The present study was undertaken in order to determine whether surgical treatment of oral leukoplakia reduces the risk of the subsequent development of carcinoma. This study included 142 patients with oral leukoplakia who received or did not receive surgical treatment. All subjects were followed-up for more than 6 months with a mean follow-up period of 4 years. Malignant transformation rate was lower among patients who received surgical excision (1/75) than among those who did not receive surgical treatments (4/51). However, the malignant transformation rates were high in patients who received cryosurgery (3/12) or cryosurgery plus surgical excision (1/4). There was no obvious relation between the grade of epithelial dysplasia and the rate of malignant transformation. Our results suggest that surgical excision of oral leukoplakia may reduce the risk of the subsequent development of carcinoma.

[Reconstruction of the soft palate with a microvascular radial flap].
BACKGROUND: A new technique for reconstruction of the soft palate using a folded microvascularized radial forearm flap is described. PATIENTS: The method has been used in 16 patients to date. RESULTS: There was no loss of the transplant. Only three patients had unsatisfactory functional results with respect to speaking and swallowing. CONCLUSIONS: The presented technique enables a one-step reconstruction of the complete soft palate. The complication rate we experienced was low and the functional results were excellent.
[Plastic reconstruction of small defects of the soft palate using the tonsil].
The tonsil is suitable for reconstruction of small defects of the soft palate after tumour resection if pedicled at the upper pole. It can be easily sutured into the defect and yields a satisfactory functional result.
A trans-orofacial approach for the removal of an extracranial meningioma in the skull base.
Two rare cases of extracranial meningiomas associated with intracranial masses are reported. From the roentgenological findings both of the tumors were regarded as being partly connected. The tumors were surgically treated 21 and 19 years, respectively, after the first removal of the intracranial masses. They appeared as nasal-oral and orbicular masses, respectively, and were histologically diagnosed as meningotheliomatous meningioma. In one case a partial removal of a naso-oral tumor, including a subtotal removal of the tumor in the lateral orbital cavity, was performed by Weber-Kocher's incision plus Krönlein's incision. In the other case a tumor was removed via a transoral route by a lateral retraction of one half of the mandible after cutting it into halves. Our operative approaches and origins of the tumor are discussed.
Versatility and donor site morbidity of the lateral upper arm flap in intraoral reconstruction.
OBJECTIVE: The lateral upper arm flap is not widely used yet for intraoral defect reconstruction. Investigation of its morphologic and functional outcome was the objective of this study. STUDY DESIGN: The morphologic and functional results of recipient (swallowing, flap survival, dehiscence of margins, cutaneous fistulas, intraoral hairs) and donor sites (wound healing, scar width and length, sensory and motor disturbance) (n = 44) were checked clinically. Postoperative swallowing was investigated via videofluorography (n = 11). RESULTS: The lateral upper arm flap showed low donor site morbidity, primary closure was achieved in all but one case. Sensory deficit at the proximal forearm (n = 27) occurred without any case of compromise of radial nerve function. Videofluorography allows for objective evaluation of swallowing function. CONCLUSIONS: The lateral upper arm flap is the reconstruction of first choice for intraoral defects due to its low donor site morbidity.
The temporalis muscle flap in reconstruction of intraoral defects: an appraisal of the technique.
PURPOSE: The purpose of this article is to review the experience of the authors in the use of the temporalis muscle flap for reconstruction of intraoral defects. PATIENTS AND METHODS: This is a retrospective review of the use of the temporalis muscle flap for reconstruction of different types of intraoral defects in 8 patients. All patients in this series previously wore obturators as a nonsurgical treatment of their defects. Criteria used to evaluate the results of this technique included flap necrosis, facial nerve deficit, limitation of mandibular range of motion, and cosmetic deformity from scarring of the incision line or from loss of muscle volume in the temporal fossa. The patients were also evaluated for their degree of satisfaction with their speech and mastication with the obturator preoperatively and with the flap postoperatively. This article also reviews the success rates and complications with use of the temporalis muscle flap reported in the English-language literature during the past 14 years. RESULTS: All 8 patients in this series had their defects successfully reconstructed, completely eliminating any further need for prosthetic obturation of the defect. There were no incidents of flap necrosis, facial nerve deficit, or long-term changes in mandibular range of motion. Slight temporal hollowing was seen in the first 3 patients. Results of the literature review also showed a high success rate and a low incidence of complications with use of this flap. CONCLUSIONS: The temporalis flap is a useful, reliable, and versatile option for reconstruction of moderate to large sized defects. The muscle can provide abundant tissue, with minimal to no functional morbidity or esthetic deformity in the donor site.
