Transcervical submandibular sialoadenectomy
No full textThe submandibular glands are subject to several pathologies that require excision. The most common problem that affects these salivary glands is sialadenitis combined with sialolithiasis. This problem occurs in the submandibular gland 10 times more frequently than it does in the parotid gland. Other illnesses frequently involving the submandibular glands are represented by sialadenosis and benign, malign, and intermediate neoplasms.Diagnosis of any disturbance in the submandibular gland involves both a clinical and instrumental (echography, traditional radiography [ortopantomography] and eventually computed tomography (CT) or magnetic resonance imaging) assessment. Surgery is the usual method of treatment of both chronic sialadenitis and neoplasms in the submandibular gland. A submandibular gland surgical approach can be cervical, intraoral, or endoscopic.The authors present their clinical experience with a total of 40 patients with illnesses involving the submandibular gland treated with submandibular gland excision by a transcervical approach. Their experience suggests that this approach entails a relatively simple procedure, involves low risks for the nerve structure around the gland, permits wide resection margins for neoplasms, and incurs little aesthetic damage. ©2007Muntaz B.

Prosthetic rehabilitation in post-oncological patients: report of two cases
Full text linkProsthetic rehabilitation in post-oncologic patients after bone reconstruction are not substantially different than those of patients affected by severe atrophia of upper or lower jaw after bone reconstruction.
Aim of this paper is to evaluate the possibilities of prosthetic rehabilitation on these patients and to present our method. Prosthesis-based oral rehabilitation of such tumor cases rapresents a challenge.
The report analyses two cases of patients who underwent ablative oral surgery. Both have received a fibula free vascularised flap. The first was rehabilitated with a removable prosthesis fixed on the residual teeth, while the second with an implant supported prosthesis. In case of carcinoma resection of the oral mucosa, the removable prosthesis guarantees a simplification in dental care operations. On the other hand, irradiated mucosa is frequentely unable to tolerate the friction created by the acrylic base. However, the fixed prosthesis can limit the view during follow-up controls. In our school, according to all exposed reasons, we consider the implant supported overdenture prosthesis to be the best choice for those patients
Growth patterns and intraoral distraction osteogenesis: craniofacial microsomia versus temporomandibular joint ankylosis
No full textIntraoral distraction osteogenesis (DO) is a mainstay for the treatment of mandibular hypoplasia. Aim of this study was to assess the long-term stability and compare the patterns of growth unilateral intraoral mandibular distraction in two groups of patients: one affected by hemifacial microsomia HFM and the other after removal of TMJ ankylosis. Seven patients with HFM and 6 patients who had previously undergone removal of TMJ ankylosis were included in the study. Records included photographic data cast models. postero-anterior (PA) and panoramic x-rays taken preoperatively, at the end of distraction and after a mean follow-up of 5.6 years. Mandibular distraction had an immediate effective role in the growth of the mandible in both groups, but in the follow-up, the comparative analysis of the two groups of patients revealed that in patients with TMJ ankylosis the rate of mandibular growth remained stable over time in the growing age, whereas in patients with HEM a slight asymmetry would progressively show on the distracted side during growth

Intra-parotid facial nerve multiple plexiform neurofibroma in patient with NF1
No full textIntroduction: Primary neurogenic tumours of facial nerve are uncommon with the majority found intratemporally. Intracranial and intra-parotid neoplastic involvement of cranial nerve VII is much less common. There are 11 reported cases, in the English -language literature, of intra-parotid facial nerve plexiform neurofibromas with eight of them associated with NF1. Materials and Methods: A child, 10 years old, with NF1, reached us for a cheek swelling, slowly increased in previous 8 years. At the age of 3 years, a plexiform neurofibroma was diagnosed by biopsy of the lesion. Clinical examination and NMR showed in the sub-cutaneous tissue of the right cheek, two contiguous nodular lesions, about 2 cm x 1.5 cm in diameter; a third neoformed lesion, about 1 cm in diameter, was located above the ipsilateral labial. commissure. No facial nerve impairment was seen. The patient underwent superficial parotidectomy with removal of the lesions and preservation of the facial nerve. Results: The patient had a considerabte regional swelling in the immediate postoperative course; no facial. nerve impairment was observed. The swelling of the cheek did not show a fully regression in the post-operative course. Ultrasonography at 3 months showed a recurrence of disease. Discussion: Plexiform neurofibromas should be distinguished due to their risk of malignant transformation seen in up to 15% of patients affected by NF1. Surgery is the only effective option currently available for the treatment of PNF. However, success of surgical intervention is limited by the infiltrating nature of the tumours, resulting in a high rate of tumour re-growth. Facial nerve preservation during surgery is unlikely and significant morbidity can result from their excision. The age of the patient at surgical resection seemed to influence outcome: tumours resected before age 10 years recurred in 60% of cases compared with only 30% recurrence in patients older than the age of 10 years. Conclusion: Indication and timing of surgery, in paediatrics patients with NF1, are complex. To avoid eventual physical and psychological consequences, it seems prudent to delay surgery as tong as it is feasible for otherwise asymptomatic paediatric patients with facial plexiform neurofibroma.

Metastases to oro-maxillo-facial region from distant sites: are they so rare? A single centre 8-years experience
No full textAIM: The goal of our study is investigate the frequency of metastasis to oro-maxillo-facial region to understand if they
are really so rare.
MATERIAL OF STUDY: In this eight year’s retrospective study (2004-2012) we collected 15 cases of metastasis localized in
the maxilla-facial region from distant primary tumor.
RESULTS: Our results show breast and kidney as the most frequent primary site (40% and 20% respectively), adenocarcinoma
as most common histological type (60%). Bone involvement has found to be much frequent than the soft tissue
one (53.3%). The mandible (5/15 cases) is more affected than the maxilla, and most common interested subsites
are molar and retromolar region. In our study we found only one case of unknown primary tumor, it was a mandibular
bone metastasis from a renal clear cell carcinoma.
CONCLUSION: Finally, according to our results and considering the increase of survival in cancer disease, even if metastases
to oro- maxilla- facial region from distant sites are not frequent, it is important to suspect secondary lesions both
in patients that was referred a tumor in their medical history and in those that present a head and neck lesion
Role of maxillofacial surgery in patients with neurofibromatosis type I
No full textNeurofibromas are a clinical manifestation of neurofibromatos is type I (NF1). Management of these tumors remains a challenge for the clinician. The goal of the present study is to point out treatment guidelines for these lesions. Eighteen patients diagnosed with NF1 and presenting lesions of the craniomaxillofacial district were included in the study. On the basis of clinical evidence and patient's expectations, only six patients of this group underwent surgery. All patients that had no surgery were included in a follow-up protocol to evaluate progression of disease. Four patients who underwent surgery had good functional/aesthetic results, whereas two patients had incomplete rehabilitation. ©2007Muntaz B. Habal, MD
