[Septal hematoma: Report of two pediatric cases].

Hematomas and septal abscesses are an emergency in rhinology and require early surgical treatment due to the risk of infectious, functional, and aesthetic complications. They generally occur as a consequence of nasal trauma, although they have also been described in relation to other triggers. Accumulation of blood or pus between the mucoperichondrium and septal cartilage, causes avascular necrosis injury to the cartilage with cartilage destruction.

[Actinomycosis in temporal bone. A pediatric case report].

Actinomycosis is an infection caused by a Gram-positive, filamentous anaerobic bacillus. Mainly belonging to the human commensal flora of the oropharynx, it normally colonizes the human digestive and genital tracts and the bronchial tree. It is slightly frequent in the temporal bone.

[Giant cell granuloma in the jaw in a 6-year-old child: A case report].

Giant cell granuloma represents a non-odontogenic tumor. It is located inside the endosteum of the jaws (central) or in the periosteum (peripheral). Although it is a benign disease process, it can also be locally destructive.

[Deep neck infections: Report of three pediatric cases].

Retropharyngeal and parapharyngeal abscesses are rare but associated with significant morbidity and potential mortality. In recent years, there has been an increase in the incidence of these infections, mainly due to a greater availability of computed tomography scan and a greater virulence of the germs (Group A b-hemolytic Streptococcus and methicillin-resistant Staphylococcus aureus). They predominate in children younger than 5 years.

[Melkersson Rosenthal syndrome. Report of two pediatric cases].

Melkersson Rosenthal syndrome is a very infrequent disease of unknown etiology, chronic and progressive course, with neurocutaneous disease that affects the orofacial innervation and mucocutaneous tissues with non-caseating granulomatous infiltration. Clinically, it is characterized by the diagnostic triad: recurrent edema of lips and/or face; recurrent and alternating acute peripheral facial paralysis and scrotal or geographic tongue. The condition generally presents as oligosymptomatic or monosymptomatic form.

[Maxillary osteomyelitis secondary to rhinosinusitis in children: case report].

Rhinosinusitis is a very common childhood condition. Osteomyelitis is an unusual complication, which mainly occurs in toddlers and young children. The most frequent etiologic agent is Staphylococcus aureus.
