Paranasal sinus osteomas are mostly asymptomatic; however, secondary mucocele can develop if they impede the natural sinus drainage. Such a mucocele can destroy the bone and extend into the adjacent structures. We report on an unusual case of frontal sinus osteoma in a 27-year-old patient, complicated by large secondary mucocele that eroded the bone and extended into the frontal lobe of the brain. ⋯ The mucocele was completely resected through bifrontobasal osteoplastic craniotomy, whereas osteoma was evacuated in its entirety by both drilling and mobilizing. Open surgical approach remains the main treatment for complicated paranasal sinus osteoma, and radical removal of intracranial mucocele is mandatory to prevent the development of life-threatening infections. Although intradural extension of a secondary mucocele is extremely unusual, head and neck surgery specialists should take this severe complication in consideration.

The aims of this report were to analyze the cases of lateral brow incision and 1-point fixation and to introduce the criteria for application of this selective approach. Among 70 patients with tripod fractures, 14 patients (20%) underwent 1-point fixation technique through lateral brow incisions. Preoperative and postoperative displacements of the infraorbital rim were radiologically measured. ⋯ After surgery, step deformities of the infraorbital rims were improved (range, 0.1-3.8 mm; mean, 1.4 +/- 0.5 mm). All 14 patients were satisfied with their postoperative appearance. Indications for using 1-point fixation of the tripod fracture are (1) minimal or moderate displacement of the infraorbital rim in the tripod fracture of the zygoma, (2) no ocular signs of diplopia or enophthalmos, and (3) comminuted infraorbital rim fractures where internal fixation is difficult.
