The airway resistance of the naso-frontal duct during and after acute frontal sinusitis. A long term follow-up of 49 trephined frontal sinuses.

A new pressure flow method for function tests and calculation of the airway resistance in the naso-frontal duct is presented. With this pressure flow technique the function and airway resistance of the naso-frontal duct was tested in 49 patients who were trephined for acute frontal sinusitis. The tests were performed during the primary healing period (0-16 days) and in a long term study 2, 6 and 12 months after operation. The patients were also checked radiologically and clinically. A prolonged healing period (more than 6 days) corresponded significantly to a high incidence of recurrent disease. With this method it is possible to define groups where recurrences might be expected because of impaired function of the naso-frontal duct.

Anterior table frontal sinus fractures.

Frontal sinus fractures cover a spectrum of injury. A series of 52 primarily treated patients from the University of Cincinnati Medical Center is presented. Initial systematic management was applied to these patients and consisted of complete radiographic evaluation supplemented by wound care and cosmetic restoration when needed. All patients were followed on a long-term basis; both clinically and radiographically. Results to date are that 49 patients have had an uneventful post-traumatic course with re-establishment of normal sinus aeration. From the cosmetic standpoint no contour revisions have been needed and only two patients required elective scar revision. Three patients developed chronic suppurative sinus disease within the first post-traumatic year which was readily diagnosed and managed without complication by osteoplastic frontal sinusotomy and adipose obliteration.

Frontal sinus fractures.

Frontal sinus fractures can have serious consequences due to the proximity of the sinus to the intracranial cavity, and the potential for nasofrontal duct obstruction with its long-term sequelae. Management of these fractures varies dependent on several factors. These include the degree of displacement of the fractures; involvement of the anterior table, the posterior table, and/or the nasofrontal duct; and the presence of cerebrospinal fluid leakage. This paper gives an overview of fracture treatment options, and offers a simple algorithm for management based on the fracture severity and involvement of the different aspects of the sinus.

[Obliteration of the frontal sinus with lyophilized cartilage in frontal fractures].

Obliteration of the frontal sinus is frequently necessary in the appropriate treatment of major craniofacial trauma of the upper third of the face. Successful frontal sinus obliteration requires (1) meticulous removal of the frontal sinus mucosa, (2) permanent occlusion of the nasofrontal duct and (3) obliteration of the denuded cavity. The current techniques include implantation of autologous fat, bone or muscle. These techniques are effective when the appropriate guidelines are respected, but the problems of donor site morbidity, which has been as high as 5%, recipient site morbidity due to the shrinkage of the free graft, and the increase in the operative time must be pointed out. The unique characteristics of lyophilized cartilage, i.e. the low resorption rate and tendency to undergo osseous substitution, justify its use for obliteration of the frontal sinus. The present study reviews 51 patients with obliteration of the frontal sinus due to craniofacial trauma. In none of the patients were there clinical or radiological signs of postoperative mucocele formation. Progressive ossification of the implanted cartilage was verified in most of the patient population.

Revision endoscopic frontal sinus surgery.

Frontal sinusitis following functional endoscopic sinus surgery may represent persistent, recurrent, or iatrogenic disease. The narrow frontal recess is unforgiving of technical errors, and surgery within its confines requires ample training, skill, and patience. Revision surgery in this area, compromised by scarring and long-standing mucosal disease, demands even more of the endoscopic sinus surgeon. While successful treatment of this condition is a formidable task, strict attention to principles of proper medical and surgical therapy can increase the chances of a favorable outcome.

Paranasal sinus radiology, part 1B: the frontal sinuses.

Alteration in the appearance of the mucosa, fluid accumulations, and change in the shape and texture of the sinus wall form the basis of the radiologic information that aids in the diagnosis of frontal sinus disease. Inflammatory disease of the frontal sinuses was discussed in Part 1A of this article; other disease processes of the frontal sinuses as they appear in the various roentgenographic modalities are described and illustrated here.

[Bicoronal approach in the management of frontal sinus fractures].

The frontal sinus is located at the level of the junction between the naso-ethmoido-orbital region, the cranial vault and the skull base and plays a particularly important role in the biomechanics of the centro-facial region. It represents a locus minoris resistentiae placed between the fronto-orbital frame, whose resistance to trauma is good, and the thin posterior fronto-ethmoidal structures. Fractures of the frontal sinus more frequently involve the anterior wall of the frontal sinus and, occasionally, also the posterior wall and the base of the sinus. Where the fracture involves the anterior sinsu wall alone, surgical reduction is indicated to correct cosmetic defects arising from an altered bone profile, either via bicoronal access or by direct attack when there are skin lesions too. If the fracture extends to the posterior wall of the sinus without causing bone displacement or dural lesion, most authors agree that only the fractures of the anterior wall should be treated to avoid obliterating the sinus cavity. When the fracture of the posterior wall is comminuted with displacement of bone fragments, there are usually dural lesions too; in this event, once dural plasty has been performed, it is necessary to cranialize the frontal sinus by demolishing its posterior wall. Fractures of the skull base, associated with a high frequency of lesion or obstruction of the sinusal ostio and severe infective complication, require cranialization of the sinus that is also separated from the cranial cavity using a median-pedicled pericranial flap. To control the point of fracture, a rigid fixation system can be employed (microplates) or osteosynthesis with metal wires that restore the eurhythm of the frontal-orbital region and simultaneously guarantee good stability of the repositioned fragments.

Frontal sinus cancer manifested as a frontal mucocele.

During the period 1972 to 1974, 12 frontal mucopyoceles were seen. Subsequently, three were shown to have an underlying neoplasm. Evaluation of the roentgenograms demonstrated minor differences between those with and those without a malignant basis. In previous reports of frontal sinus cancer, the descriptions of the roentgenograms suggest that it is possible that these features were also present. The difficulty in deciding the sinus of origin in such cancers has often been discussed, but the possibility that neoplasms of the orbital lobe of the lacrimal gland may occur in the frontal sinus is usually not considered. Anatomically, the intimate proximity of this lobe to the frontal sinus suggests that a neoplasm could develop in this manner. I believe that this was true in two of the patients reported herein.

3D computed tomographic analysis of frontal recess anatomy in patients without frontal sinusitis.

OBJECTIVE: Describe frontal sinus pneumatization in patients with no history of frontal sinus disease. STUDY DESIGN AND METHODS: All 1-mm axial sinus CT scans performed from 2001 through 2003 were eligible for review on a CBYON Suite workstation (CBYON, Mountain View, CA). Exclusion criteria included frontal sinusitis, sinonasal polyposis, age < 18 years, sinus malignancy, fibroosseous lesions, maxillofacial trauma, congenital anomaly, and sinus surgery. RESULTS: A total of 50 patients met the inclusion criteria. The prevalence of each structure was: agger nasi cell (89%), type 1 frontal cell (37%), type 2 frontal cell (19%), type 3 frontal cell (8%), type 4 frontal cell (0%), supraorbital ethmoid cell (62%), suprabullarcell (15%), frontal bullar cell (9%), interfrontal septal cell (14%), and recessus terminalis (22%). CONCLUSIONS: This study describes frontal pneumatization in patients without a history of conditions that influence frontal pneumatization. The results characterize normal frontal recess/sinus pneumatization patterns.

Subdural empyema and blindness due to cavernous sinus thrombosis in acute frontal sinusitis.

In this era of antibiotics, the complications of acute sinusitis are much less frequently encountered. Although orbital complications are most common, intracranial complications carry a high rate of mortality and morbidity. We describe a case of acute frontal sinusitis with subdural empyema and blindness due to cavernous sinus thrombosis and carotid artery thrombosis with a discussion of treatment of these complications and the etiology of blindness in sinusitis.

Resection of the interfrontal sinus septum in chronic or recurrent frontal sinusitis. Pre- and post-operative evaluation of the naso-frontal duct.

In 9 patients with recurrent attacks of acute or chronic frontal sinusitis, interfrontal sinus septum resection was performed. In 5 patients there was unilateral disease and in 4 bilateral. As all patients had previously had their frontal sinus trephined, pre- and post-operative naso-frontal duct function tests were performed. Pre-operatively, of 11 naso-frontal ducts tested (2 patients bilaterally) not one showed air flow on spontaneous respiration. Passage of air was obtained at forced inspiration and expiration in one patient and by Valsalva's manoeuvre in 6. No flow of air whatsoever was obtained in 4 of the ducts, whatever the method used. At follow-up performed 1-8 years post-operatively 7 out of the 9 patients had no frontal sinus problems. The remaining 2 patients, who both had nasal allergy, were improved. Post-operative testing of the 9 patients showed flow of air on spontaneous respiration in 4 patients, whereas 4 needed forced inspiration or expiration and only one patient Valsalva's manoeuvre. The sinus septum resection, which is very simple to perform, is a good alternative to more extensive frontal sinus surgery but may be of less value in patients with nasal allergy.
