Use of anteriorly based pericranial flap in frontal sinus obliteration.
ABSTRACT In an era of endoscopic sinus surgery, frontal sinus obliteration continues to remain an important treatment option in chronic frontal sinus disease. Numerous avascular obliterative materials including fat, muscle, cancellous bone, and hydroxyapatite have been used in this procedure. In this article, we describe a vascularized anteriorly based pericranial flap to obliterate frontal sinus.
Retrospective chart review of patients referred to tertiary care hospital between 1996 and 2003.
Records of the patients who underwent this procedure were reviewed. Demographics, indications, and immediate and late complications were recorded. A phone questionnaire was used to assess patient satisfaction with the outcome.
A total of 12 patients underwent frontal sinus obliteration with this technique. Mean follow-up was 40 months. None of the patients developed recurrent frontal sinusitis. All of the patients were pleased with the outcome.
Pericranial flap is a highly vascularized flap that is easily harvested and is an effective and viable modality for obliterating frontal sinus. EBM rating: C-4.

ABSTRACT: To compare frontal sinus cranialization to obliteration for future prevention of secondary mucocele formation following open surgery for benign lesions of the frontal sinus. Retrospective case series. Tertiary academic medical center. Sixty-nine patients operated for benign frontal sinus pathology between 1994 and 2011. Open excision of benign frontal sinus pathology followed by either frontal obliteration (n = 41, 59%) or frontal cranialization (n = 28, 41%). The prevalence of post-surgical complications and secondary mucocele formation were compiled. Pathologies included osteoma (n = 34, 49%), mucocele (n = 27, 39%), fibrous dysplasia (n = 6, 9%), and encephalocele (n = 2, 3%). Complications included skin infections (n = 6), postoperative cutaneous fistula (n = 1), telecanthus (n = 4), diplopia (n = 3), nasal deformity (n = 2) and epiphora (n = 1). None of the patients suffered from postoperative CSF leak, meningitis or pneumocephalus. Six patients, all of whom had previously undergone frontal sinus obliteration, required revision surgery due to secondary mucocele formation. Statistical analysis using non-inferiority test reveal that cranialization of the frontal sinus is non-inferior to obliteration for preventing secondary mucocele formation (P<0.0001). Cranialization of the frontal sinus appears to be a good option for prevention of secondary mucocele development after open excision of benign frontal sinus lesions.PLoS ONE 01/2013; 8(12):e83820. · 3.53 Impact Factor

ABSTRACT: Even with the widespread use of minimally invasive endoscopic sinus surgery, the treatment of complicated frontal sinus disease remains very challenging, and obliteration of the sinus often is indicated. A variety of materials have been used for obliteration of the frontal sinus; however, the search for the ideal technique persists. The well-vascularized anteriorly based pericranial flap, described in this article, is a safe, effective, and viable method of frontal sinus obliteration.Operative Techniques in Otolaryngology-Head and Neck Surgery 01/2009; 20(2):88-91.

ABSTRACT: Inappropriate treatments of frontal sinus fractures may lead to serious complications, such as mucopyocele, meningitis, and brain abscess. Assessment of nasofrontal duct injury is crucial, and nasofrontal duct injury requires sinus obliteration, which is often accomplished by autogenous grafts such as fat, muscle, or bone. These avascular grafts have an increased risk of resorption and infection and donor site morbidity. For these reasons, pericranial flap, which is vascular, should be used for frontal sinus obliteration. The pericranial flap presented with less morbidity procedure and has decreased infection rates, which justifies its use in frontal sinus obliteration. This study aimed to report a case of a comminuted frontal sinus fracture with a brief literature review, regarding the use of pericranial flap. The authors report a case of a 23-year-old male subject with a severely comminuted fracture of the anterior and posterior walls of the frontal sinus. The patient was successfully treated by cranialization with frontal sinus duct obliteration, using anterior pericranial flap. The patient was followed up for 16 months with no postoperative complication, such as infection. Pericranial flap is a good resource for frontal sinus duct obliteration because it is a durable and well-vascularized flap, which determines low rates of postoperative complications.The Journal of craniofacial surgery 03/2013; 24(2):e147-9. · 0.81 Impact Factor
