Osteoma frontoetmoidal, otras aplicaciones del Draf III, a raíz de un caso clínico / Frontoethmoidal osteoma, other applications of Draf III on the grounds of a clinical case

Presentamos el caso de una mujer de 57 años, que consulta tras notar un aumento de volumen pétreo y de lento crecimiento en el reborde orbitario medial derecho, asociado a obstrucción nasal, anosmia y descarga posterior. La evaluación clínico radiológica evidenció un gran osteoma frontoetmoidal derecho con compromiso orbitario y de la lamela lateral de la lámina cribosa, y además, una rinosinusitis crónica con pólipos. Se realizó una resección endoscópica del tumor por medio de un Draf III y una cirugía endoscópica funcional del resto de las cavidades perinasales para el tratamiento de la rinosinusitis crónica. Describimos el caso y discutimos sus aspectos relevantes.

We report the case of a 57 year-old woman consulting because of a slow growing solid tumor in the right medial orbital rim associated with nasal obstruction, anosmia and posterior nasal drip. Clinical and radiological evaluation evidenced a large right frontoethmoidal osteoma involving the orbit and thelateral lamella of the cribriform plate, and chronic rhinosinusitis with polyps. A Draf III was performed to remove the osteoma and a bilateral functional endoscopic sinus surgery of the remaining sinuses was performed to treat thechronic rhinosinusitis. We described the case and discuss its relevant aspects.

Endonasal ethmoidectomy and bifrontal craniotomy with craniofacial approach for resection of frontoethmoidal osteoma causing tension pneumocephalus.

Tension pneumocephalus is an unusual, potentially life-threatening complication of frontal fossa tumors. We present an uncommon case of a frontoethmoidal osteoma causing a tension pneumocephalus and neurological deterioration prompting a combined endonasal ethmoidectomy and bifrontal craniotomy with craniofacial approach for resection. A 68-year-old man presented with a 1-week history of worsening headache, slowness of speech, and increasing confusion. Standard computed tomography scan revealed a marked tension pneumocephalus with ventricular air and 1-cm midline shift to the right. Further studies showed a calcified left ethmoid mass and a left anterior cranial-base defect. A team composed of neurosurgery and otolaryngology performed a combined endonasal ethmoidectomy and bifrontal craniotomy with craniofacial approach to resect a large frontoethmoid bony tumor. No abscess or mucocele was identified. The skull base defect was repaired with the aid of a transnasal endoscopy, a titanium mesh, and a pedunculated pericranial flap. Postoperatively, the pneumocephalus and the patient's symptoms completely resolved. Pathology was consistent with a benign osteoma. This is an uncommon case of a frontoethmoidal osteoma associated with tension pneumocephalus. Recognition of this entity and timely diagnosis and treatment, consisting of an endonasal ethmoidectomy and a bifrontal craniotomy with craniofacial approach, may prevent potential life-threatening complications.
