Ameloblastoma desmoplásico / Desmoplastic ameloblastoma

Presentamos un caso de ameloblastoma desmoplásico en una mujer de 32 años que afectaa la región media del maxilar superior. Se describen las características específicas, tantohistológicas como clínicas, de esta variante de ameloblastoma, y se insiste en su imagenradiológica similar a la de una lesión fibroósea benigna. Se indica la misma conducta terapéuticaque para el resto de los ameloblastomas intraóseos sólidos(AU)

We report a case of desmoplastic ameloblastoma in a 32 year-old female patient affectingthe region half of the upper jaw. We describe the specific characteristics, both histologicaland clinical of this variant of ameloblastoma, insisting its radiological image similar to thatof a benign fibroosseous lession. We indicate the same therapeutic conduct for the rest ofthe solid intraosseous ameloblastomas(AU)

Fascitis nodular en el territorio maxilofacial. Presentación de dos casos y revisión de la literatura / Nodular fascitis of the maxillofacial region. Two case reports and a review of the literature

La fascitis nodular es una entidad clínica relativamente poco frecuentecaracterizada por una tumoración de crecimiento rápido, aunquede comportamiento clínico benigno y de características histológicas pseudosarcomatosas.Su aparición en el territorio maxilofacial es poco común,por lo que presentamos dos casos que acudieron por nódulos de consistenciadura, indoloros, en las regiones cigomática y paramandibular, quefueron diagnosticados de fascitis nodular. Destacamos estos casos por tratarsede fascitis nodular de localización atípica y revisamos su histopatología(AU)

Nodular fasciitis is a relatively rare clinical entity that ischaracterized by a rapidly growing tumor-like mass, although it hasa benign clinical behavior and pseudosarcomatous histological characteristics.Its appearance in the maxillofacial area is unusual, andtwo cases are presented of patients that attended as a result ofnodules that were hard in consistency, non-tender, in the zygomaticregion beside the mandible, and that were diagnosed as nodularfasciitis. The cases are highlighted because of the atypical locationof the nodular fasciitis and the histopathology is revised(AU)

Osteotomía de avance del marco orbitario para el tratamiento del exoftalmos endocrino severo / Advancement osteotomy of the orbital rim for the treatment of severe endocrine exophthalmos

La orbitopatía tiroidea es una enfermedad debilitante del sistemavisual caracterizada por presentar cambios en los tejidos blandos orbitariosy periorbitarios debidos a un proceso inflamatorio, o a la consecuenciadel mismo, y que se relaciona con alteraciones sistémicas de la glándulatiroides. Aparte de las alteraciones estéticas que ocasiona, los pacientespueden presentar queratitis de repetición por exposición, diplopia, dolorretrobulbar, compresión del nervio óptico e incluso ceguera. La cirugíaconstituye el tratamiento definitivo del exoftalmos en la orbitopatía deGraves, mejorando la proptosis y la visión, así como diminuyendo la sintomatologíaocular, con una morbilidad mínima. Presentamos un casode exoftalmos severo que fue intervenido mediante osteotomía y avancedel marco orbitario superior, lateral e inferior, remoción parcial de dos paredesorbitarias y lipectomía. Los resultados estéticos y el alivio de la sintomatologíaocular resultaron satisfactorios

Thyroid-associated orbitopathy is a debilitating diseaseof the visual system that is characterized by changes in the softtissuesof the orbit and periorbita as a result of an inflammatoryprocess, or as a consequence of this, and related to systemic disordersof the thyroid gland. Apart from the aesthetic changes that arise,patients may also present persistent keratitis due to exposure,diplopia, retrobulbar pain, compression of the optic nerve and evenblindness. Surgery represents the definitive treatment forexophthalmos in Graves’ orbitopathy as improvements are shownin proptosis and vision. A decrease is also experienced in ocularsymptomatology and there is minimal morbidity. We present thecase of severe exophthalmos that was surgically operated on withan advancement osteotomy of the supero-, lateral- and infraorbitalrim, with partial removal of two of the orbital walls with lipectomy.The aesthetic results and the relief of the ocular symptoms weresatisfactory

Retromolar intubation.

PURPOSE: A simple technique of retromolar intubation does not interfere with dental occlusion and offers clear advantages in craniofacial, orthognathic, oncologic, and trauma surgery procedures. PATIENTS AND METHODS: Thirty-nine subjects underwent different surgical procedures using this intubation technique. The possible surgical and anesthetic complications were analyzed. RESULTS: After the analysis of the studied variables and modes, we noticed that there was not a significant increase in complications or surgical time compared with other classic intubation methods. A retromolar bone graft could be obtained if necessary. CONCLUSION: This technique does not impede operating on the nasal pyramid and allows intraoperative assessment of the new surgical profile, while permitting establishment of normal occlusion.

A pseudo-tumour of the mandible in a haemophiliac patient. A case report.

The presence of a rare pseudo-tumour of the mandible in a haemophiliac justifies the presentation of this case in which the history and the clinical and radiological examinations were sufficient for a presumptive diagnosis. The authors present a case of pseudo-tumour of the mandible in a boy, with a history of haemophilia following a traumatic injury. They comment on the clinical and radiological aspects and surgical technique employed. The patient underwent the surgical treatment after the administration of 1000 U. of factor VIII. The whole pseudo-tumour was removed. The postoperative follow up one year after surgery was normal both clinically and radiologically.

Bony reconstruction in the orbital region.

The author discusses the various problems that can arise in the static or dynamic state in the eyeball, the eyelids, and the lacrymal canals--due to alterations of the bony orbit. Reconstruction techniques in the orbitomaxillomalar, orbitonasal, and frontoorbital regions are dealt with separately, with emphasis on the need for a global and primary solution to all the alterations. Particular attention is payed to some cases of fibrous dysplasia in the frontoorbital region that were treated with reimplantation of the same dysplasic bone after it was remodeled. This is a personal technique that is suggested as an alternative treatment for this kind of lesion.
