Frontal sinus obliteration with the pericranial flap
1Department of Otolaryngology, SUNY-Brooklyn, NY, USA.
Background:
Frontal sinus obliteration is often accomplished by autologous grafts such as fat, muscle, or bone. These avascular grafts carry an increased risk of resorption and infection as well as donor site morbidity. Vascular regional flaps may be used to obliterate small sinuses with less morbidity.
Objectives:
To review our experience with the use of the pericranial flap for obliteration of the frontal sinus.
Methods:
The records of 10 patients who underwent obliteration of the frontal sinus with the pericranial flap were reviewed. Demographics, indications for frontal sinus obliteration, immediate and late complications, and long-term outcome were recorded. These results were compared with those in the current literature.
Results:
Ten sinuses were obliterated with the pericranial flap. Indications included frontal sinus mucocele, mucopyocele, frontal sinus osteomyelitis, and frontal sinus fracture. The median follow-up was 3 years. There was 1 short-term complication of persistent headache for 1 month, and there was asymptomatic recurrence of a neofrontal sinus in 1 case.
Conclusions:
The pericranial flap is a vascularized local flap that is easily harvested. The use of the pericranial flap avoids donor site morbidity associated with free fat or cancellous bone grafts. The pericranial flap arms the head and neck surgeon with an effective alternative to other methods of frontal sinus obliteration.

01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
