Surgical Approach of Maxillary Cysts in Pediatric Patients: Report of Two Clinically Similar Cases with Different Diagnosis

Extensive odontogenic cysts in children may represent surgical challenges, as they may have common clinical characteristics and different approaches. The main objective of this study is to compare two cases of pediatric odontogenic cysts in maxilla with similar surgical treatment and different histopathological diagnosis. The case series collected included two children, both 12 years old, with encapsulated osteolytic lesions in the region of the maxilla and zygoma body, with clinical and imaging characteristics that suggested odontogenic cysts. The histopathological diagnosis was dentigerous cyst and radicular cyst. In this way, we address the clinical-surgical diagnostic and therapeutic process adopted, analyzing clinical data, such as signs and symptoms, as well as pre- and postoperative tomography scans. Outpatient visits at regular intervals were planned. Both patients achieved significant regression of initial signs and symptoms and returned to their daily activities. It is noticeable that a good stratification of surgical need and planned action in diagnosis and surgery offer benefits with a favorable prognosis for pediatric odontogenic cysts of the jaw.

Los quistes odontogénicos extensos en niños pueden representar desafíos quirúrgicos, ya que pueden tener características clínicas comunes y diferentes abordajes. El objetivo principal de este estudio fue comparar dos casos de quistes odontogénicos en mandíbulas de niños con tratamiento quirúrgico similar y diagnóstico histopatológico diferente. La serie de casos recolectada incluyó dos niños, ambos de 12 años, con lesiones osteolíticas encapsuladas en la región mandibular y cuerpo cigomático, con características clínicas e imagenológicas que sugerían quistes odontógenos. El diagnóstico histopatológico fue quiste dentígero y quiste radicular. De esta manera abordamos el proceso diagnóstico y terapéutico clínico-quirúrgico adoptado, analizando datos clínicos, como signos y síntomas, así como tomografías pre y postoperatorias. Se planificaron visitas ambulatorias a intervalos regulares. Ambos pacientes lograron una regresión significativa de los signos y síntomas iniciales y regresaron a sus actividades diarias. Se destaca que una buena estratificación de la necesidad quirúrgica y una acción planificada en diagnóstico y cirugía ofrecen beneficios con un pronóstico favorable para los quistes odontogénicos de la mandíbula en pediatría.

Hemi Le Fort III Fracture with Subdural and Subarachnoid Pneumocephalus with a Mild Mount Fuji Sign

ABSTRACT: Extensive fractures in the fixed facial skeleton combined with traumatic brain injury can cause functional and esthetic impairments, possibly threatening the patient's life. Male patient, 50-year-old, victim of physical aggression, presented with persistent headache and dizziness, fractures in the naso-orbito-ethmoidal, zygomatic-maxillary and right pterygoid process regions, among other minor patterns of facial fracture, with mobility to maxillary traction of the third midface unilaterally. Clinical-imaging findings revealed a Hemi Le Fort III fracture and subdural and subarachnoid pneumocephalus with a mild Mount Fuji Sign. The proposed treatment was facial osteosynthesis and conservative intravenous drug treatment of the pneumocephalus. The patient had a good recovery, with no postoperative motor or functional deficits. The correct management of the patient with facial trauma associated with craniotrauma offers benefits, restoring stability of facial architecture and preventing or correcting neurosurgical complications.

RESUMEN: Las fracturas extensas en el esqueleto facial combinadas con una lesión cerebral traumática pueden causar deficiencias funcionales y estéticas, que posiblemente pongan en peligro la vida del paciente. Paciente de sexo masculino, 50 años, víctima de agresión física, que presentó cefalea persistente y mareos, fracturas en las regiones naso-orbito-etmoidal, cigomático-maxilar y pterigoides derecha, entre otros patrones menores de fractura facial, con movilidad a tracción maxilar del tercio medio facial unilateralmente. Los hallazgos de las imágenes clínicas revelaron una hemifractura de Le Fort III y neumocefalia subdural y subaracnoidea con un leve signo del Monte Fuji. El tratamiento propuesto fue la osteosíntesis facial y el tratamiento farmacológico intravenoso conservador de la neumocefalia. El paciente tuvo una buena recuperación, sin déficit motor ni funcionales postoperatorios. El manejo adecuado del paciente con trauma facial asociado a craneotrauma ofrece beneficios, devolviendo la estabilidad de la arquitectura facial y previniendo o complicaciones neuroquirúrgicas.

Angina bullosa haemorrhagica: A 14-year multi-institutional retrospective study from Brazil and literature review

Background: Angina bullosa haemorrhagica (ABH) is characterized by the recurrent appearance of blood blisters on the oral mucosa, mainly in adults' soft palate. In general, the blisters rupture spontaneously, lacking the necessity for biopsy. We report the clinical features of 23 ABH cases, emphasizing the clinical behavior and the management of these conditions. Material and Methods: A retrospective descriptive cross-sectional study was performed. A total of 12,727 clinical records of oral and maxillofacial lesions from four dental services in Brazil were analyzed. Clinical data were collected from the clinical records and evaluated. Results: The series comprised 12 males (52.2%) and 11 females (47.8%), with a mean age of 56.8 ± 14.6 years (ranging: 24-82 years) and a 1.1:1 male-to-female ratio. Most of the lesions affected the soft palate (n = 15, 65.2%). Clinically, the lesions presented mainly as an asymptomatic (n = 17, 73.9%) blood-filled blister that ruptured after a few minutes or hours, leaving an erosion. The masticatory trauma was the most frequent triggering event. No patient had coagulation disorders. A biopsy was performed in only four cases (17.4%). Treatment was symptomatic with a favorable outcome. Conclusions: ABH is still poorly documented in the literature, and its etiology remains uncertain. ABH mainly affects the soft palate of elderly adults and has a favorable evolution in a few days. The therapeutic approach is often focused only on the relief of symptoms. However, it can share some clinical features with more serious diseases. Therefore, clinicians must recognize these lesions to avoid misdiagnosis.(AU)
