An Atypical Path of the Lingual Nerve in the Retromolar Region: Incidence in Oral Surgery.

The Lingual nerve is frequently anesthetized during oral, maxillofacial, or otorhinolaryngology surgery. It originates below the oval hole in the infratemporal region, follows its path down and forward, and moves away from the medial surface of the ramus. From there, it goes just above the mylohyoid line. It approaches the lateral margin of the tongue and crosses the Wharton's canal, and divides into numerous branches. Some cases of temporomandibular joint syndrome or myofascial pain syndrome could be a result of its anatomical variations. Also, the jurisprudence has always condemned the practitioner if for not demonstrating that the path of the injured nerve presents an anomaly which makes his involvement inevitable. The purpose is to present one of the multiple atypical paths of the lingual nerve not described in the retromandibular trigone, demonstrating that its damage constitutes a risk that cannot be controlled.

Diode laser photocoagulation of intraoral (and perioral) venous malformations: Cases series.

Vascular anomalies are subdivided into vascular tumors (hemangiomas) and vascular malformations. They are frequently located in the head, neck, and oral cavity. They are common complaints reported in patients seeking treatment for aesthetic or functional issues. However, recent advances in the diagnosis and management of these lesions are improving treatment strategies. This review provides both basic and up-to-date knowledge on the most common vascular anomalies encountered by practitioners. Due to the wide variability of treatment options which often generates debate, this paper work aims to provide a comprehensive approach of these lesions based upon current concepts and practical clinical experience. Our article is about 4 patients who had consulted for one or several purplish, elevated, well limited and soft lesion. These lesions was not painful, but worrying for patients. Therapies for VAs continue to generate a dilemma for oral surgeons. Several treatment options were reported, including conventional surgery with or without adjunctive preoperative embolization, and drug therapies, such corticosteroids, intralesional injection of corticosteroids and intralesional injections of sclerosing agents. All of these therapeutic approaches carry a high risk of severe side effects such as scars, pain, and bleeding [7]. Nowadays, advances in the use of lasers have allowed doctors an effective treatment with minimal side effects [9]. All our cases described in this article were done by Pr Haitami, using the 980 nm Diode laser, and a complete healing was observed in about 8 months at the most. The laser is therefore a great help in the management of this type of lesion.

Odontome composé: à propos d'un cas clinique

Les odontomes sont des tumeurs bénignes des maxillaires composées de dérivés de l'épithélium odontogène et de l'ectomésenchyme. Ils sont divisés en deux groupes: odontome composé et odontome complexe. L'odontome composé est constitué de nombreuses dents rudimentaires, de très petite taille, groupées dans un sac dont la paroi conjonctive est identique à celle du follicule dentaire normal. Il s'agit d'une jeune patiente qui s'est présentée à la consultation pour une tuméfaction maxillaire antérieure évoluant depuis 4 ans. La patiente a rapporté qu'elle a subi un traumatisme à l'enfance. L'évolution de la tuméfaction était asymptomatique. L'examen exobuccal était sans spécificité. L'examen endobuccal a montré la présence au niveau de la muqueuse vestibulaire du maxillaire antérieur, d'une tuméfaction dure à la palpation et indolore. La muqueuse de recouvrement était d'aspect normal. La TDM a montré des images radiopaques entourées d'un halo radioclaire au niveau du secteur maxillaire antérieur droit autour de la racine de la 11, avec une rupture de la corticale externe et sans envahissement des fosses nasales. Les données cliniques et radiologiques ont orienté vers un odontome composé. Une exérèse chirurgicale des odontomes a été réalisée. L'odontome fait partie des tumeurs odontogéniques benignes épithélio-mésenchymateuses mixtes. L'étiologie de l'odontome est inconnue. Il peut apparaître suite à un ancien traumatisme. Les odontomes composés sont asymptomatiques et découverts au cours d'un examen radiographique de routine. Le traitement consiste à l'extraction chirurgicale de l'odontome seule ou suivi d'un traitement orthodontique en cas d'inclusion d'une dent

Odontomas are benign jaw tumors composed of derivatives of odontogenic epithelium and ectomesenchyme. They are divided into two groups: compound odontoma and complex odontoma. A compound odontoma is made up of many rudimentary teeth, very small, grouped in a sac whose connective wall is identical to that of the normal tooth follicle. A young patient presented for the consultation for an anterior maxillary swelling that has progressed for 4 years. The patient reported that she suffered trauma as a child. The progression of the swelling was asymptomatic. The extra oral examination was unspecific. Intraoral examination showed the presence in the vestibular mucosa of the anterior maxilla, a swelling that was hard on palpation and painless. The covering mucosa was normal in appearance. CT showed radiopaque images surrounded by a radiolucent halo in the right anterior maxillary sector around the root of 11, with a rupture of the external cortex and without invasion of the nasal cavity. Clinical and radiological data have pointed to a compound odontoma. Surgical removal of the odontomas was performed. Odontoma is one of the benign mixed epithelial-mesenchymal odontogenic tumors. The etiology of odontoma is unknown. It can appear following an old trauma. Compound odontomas are asymptomatic and discovered during routine radiographic examination. Treatment consists of surgical extraction of the odontoma alone or followed by orthodontic treatment in the event of inclusion of a tooth.

Detection of potentially malignant lesions and squamous cell carcinomas in consultation of surgical denstitry.

UNLABELLED: Squamous cell carcinoma can occur on a apparently healthy mucosa or be preceded by lesions Chronic called potentially malignant, often asymptomatic, rarely showing the reason for consultation of patients, particularly in our Moroccan background which is  characterized by a care difficulty of access and the absence of priority to oral health. OBJECTIVE: To assess the prevalence of diseases potentially and malignant squamous cell carcinomas, and the role of certain risk factors in the onset of these lesions. METHODS: In the consultant population center Dental Consultation and Treatment of Casablanca CHU, we conducted a descriptive survey with 306 patients seen for different patterns between May and July 2010. RESULTS: 64.7% of the population had a defective hygiene. In addition, for 40 patients having an oral lesion mucosa, only 16 viewed for these lesions; the others were diagnosed incidentally. Five of these lesions were carcinomas, 32 white lesions of leukoplakia and 256 lichen planus. 7.2% of the population was smoking which nearly half were alcolo-smoking. The most risk factor according to this study significant is the alcohol and tobacco intoxication. CONCLUSION: This study confirms the importance of early screening of  symptomatic chronic lesions potentially malignant as well as squamous cell carcinoma which allows to improve prognosis.
