“…These osteomas are most commonly found in the frontal and ethmoid sinuses, but may occur in the external auditory canal, glenoid fossa, and styloid process. 3 6 11 12 In the general population, craniofacial osteomas account for 0.43% of tumors, and as well as 1% of incidental findings on plain radiographs and 3% of incidental findings on CT exams. 8 13 Maxillofacial osteomas are classified as peripheral osteomas and most commonly arise in the mandible, followed by the maxilla, temporal bone, and maxillary sinus.…”

“…La forma central deriva del endosteum; la forma periférica, del periostio; mientras que la extraósea se desarrolla en las estructuras del tejido muscular. La variante periférica es la más común, pues afecta con mayor frecuencia los senos paranasales y rara vez se presenta en la superficie lingual y el borde inferior del cuerpo de la mandíbula ( 2,3,(13)(14)(15)(16)(17) ).…”

El osteoma es una lesión osteogénica benigna, derivado de hueso compacto o esponjoso. Se caracteriza por ser de crecimiento lento y aparece con más frecuencia entre los 20 y los 50 años de vida, con una prevalencia mayor en hombres con respecto a las mujeres. Clínicamente asintomáticos, los podemos encontrar en la región craneofacial, particularmente en los senos paranasales y la mandíbula, y pueden presentarse de tres formas: central, periférica y extraósea, siendo más comunes los solitarios, a diferencia de los múltiples que están relacionados con el síndrome de Gardner. El tratamiento de los osteomas es quirúrgico cuando causan complicaciones. Los estudios por imágenes, como la radiografía panorámica y la TCHC, son las modalidades de mayor uso para determinar la ubicación, la extensión y las relaciones anatómicas de la lesión. Las características imagenológicas pueden presentarse como una excrecencia ósea de hueso compacto, esponjoso o mixto. El conocimiento de esta lesión nos permitirá tener mejores propuestas diagnósticas.

Background Osteomas are benign slow-growing tumors, which typically arise on the surface of the bone. They rarely arise from the temporal bone, accounting for 0.1–1% of all benign tumors of the skull. The external auditory canal (EAC) is the most common site for osteomas in the temporal bone. Other extra-canalicular osteomas of the temporal bone are uncommon and infrequently reported. In this case report, we discuss the clinical presentation and surgical management of osteoma of the squamous part of the temporal bone. A limited review of literature is also presented. Case presentation A 20-year-old male presented to the outpatient department (OPD) with a chief complaint of a hard swelling above his left ear, for 4 years. He had no other complaints other than cosmetic concern. On examination, there was a solitary, smooth, bony hard swelling just antero-superior to the left pinna, and the overlying skin was unremarkable. The left EAC and tympanic membrane were normal. A non-contrast computed tomography (CT) scan of the head and face with 3-D reconstruction showed a16 × 18 mm exophytic, pedunculated bony lesion arising from the squamous part of the temporal bone suggestive of an osteoma. The patient was taken up for surgical excision under general anesthesia. The bony lesion was removed from its attachment to the skull using a gouge and a mallet. The base of the tumor was drilled using a polishing burr to ensure complete removal and prevent recurrence. The histopathology was confirmatory of compact osteoma. Postoperative period was uneventful, and follow-up at 18-month post-surgery did not reveal any recurrence clinically. Conclusion Osteoma of the temporal squama is rarely reported, and surgical excision is the definitive treatment if symptomatic. This case report highlights the surgical management of this rare tumor. A limited review of literature suggests that squamous part of the temporal bone is an unusual site for extra-canalicular osteomas, and the prognosis is good after surgery.
