BACKGROUND: Osteomas are the most common primary bone tumors of the calvaria, with an incidence of less than 0.5%. In skull vault osteomas, the exostotic form that grows from the outer table is more common than the enostotic ones which arise from the inner table and grow intracranially. Osteomas of the forehead are very noticeable and disfiguring; patients usually seek medical advice for cosmetic reasons. Forehead osteomas were traditionally excised via either a direct incision over the lesion using the naturally occurring creases or a conventional bicoronal flap. More recently, endoscopic approaches for excision of forehead osteomas were introduced. The results were very encouraging and the technique was adopted by many groups worldwide yet with many technical variations. In this chapter we elaborate on the surgical technique and nuances of the fully endoscopic resection of frontal osteomas.

METHODS: From a prospective database of endoscopic procedures maintained by the senior author, clinical data, imaging studies, operative charts, and videos of cases of forehead osteomas were retrieved and analyzed. The pertinent literature was also reviewed.

RESULTS: The surgical technique of the fully endoscopic resection of frontal osteomas was formulated.

CONCLUSION: The endoscopic technique has many advantages over the conventional procedures. In our hands, the technique has proven to be less time-consuming, efficient, and minimally invasive with excellent cosmetic results.

Mucoceles are expansile masses originating in the sinuses. They are relatively unusual, occurring most frequently at fronto-ethmoidal region. They are locally destructive. This expansile lesion caused bony erosion and displaces the adjacent structures. We report a case of a patient who presented to our clinic with bulging of his left eye and worsening of the left vision. This was preceded by history of sport injury to his left supraorbital ridge. CT scan revealed that there was an extraconal lesion at the superolateral part of the left orbital cavity which pushed the orbit inferomedially, which consistent with left frontomucocele. He underwent enucleation of the lesion via 3 windows created namely at the left supraorbital ridge, anterior table of left frontal sinus and through the septum separating the frontal sinuses.

PMID: 8274120

A total of 76 patients with traumatic extradural haematoma were treated within a period of 3 years. Four patients developed delayed extradural haematomas. These cases are reported in view of the unusual sequence and the importance of early diagnosis.

PURPOSE: The present study investigated the effect of piezoelectric sutural ostectomies on accelerated bone-borne sutural expansion.

MATERIALS AND METHODS: Sixteen male New Zealand white rabbits (20 to 24 weeks old) were randomly divided into 4 experimental groups (n = 4): group 1, conventional rapid sutural expansion; group 2, accelerated sutural expansion; group 3, accelerated sutural expansion with continuous ostectomy; and group 4, accelerated sutural expansion with discontinuous ostectomy. All sutural ostectomies were performed using a piezoelectric instrument (Woodpecker DTE, DS-II, Guangxi, China) before expander application with the rabbits under anesthesia. Modified hyrax expanders were placed across the midsagittal sutures of the rabbits and secured with miniscrew implants located bilaterally in the frontal bone. The hyrax expanders were activated 0.5 mm/day for 12 days (group 1) or with a 2.5-mm initial expansion, followed by 0.5 mm/day for 7 days (groups 2 to 4). After 6 weeks of retention, the bone volume fraction, sutural separation, and new bone formation were evaluated using micro-computed tomography and histomorphometry. Statistical analysis was performed using Kruskal-Wallis and Mann-Whitney U tests and Spearman's rho correlation (P

Fulltext Tuberculosis of the skull mimicking a bony tumor

We present a rare case of calvarial tuberculosis mimicking a solitary bone tumor, which was surgically removed. A 52-year-old female presented with a right forehead swelling, which gradually enlarged over the course of 2 years, with no symptoms or raised intracranial pressure or neurological deficits. Plain and contrast-enhanced brain computed tomography scans were done, revealing a punched-out lesion of the right frontal bone, with a nonenhancing lytic mass. With an initial diagnosis of an intraosseous meningioma, and later on intraoperatively thought to be a metastatic tumor, the mass was excised along with a rim of bone. Histopathological examination results came back as caseous necrosis, highly suggestive of tuberculosis. The patient was then treated with a 1 year regimen of anti-tuberculous medications. Tuberculosis of the cranium is a rare entity, and can mimic tumors or multiple myeloma. A high index of suspicion and knowledge is required for an early diagnosis. A combined surgical and medical therapy is curative.

Reproducibility of facial soft tissue landmarks on facial images captured on a 3D camera

PMID: 23785939

Fast and non-invasive systems of the three-dimensional (3D) technology are a recent trend in orthodontics. The reproducibility of facial landmarks is important so that 3D facial measurements are accurate and may-be applied clinically. The aim of this study is to evaluate the reproducibility of facial soft tissue landmarks using a non-invasive stereo-photogrammetry 3D camera.

Frontoethmoidal encephalocele: treatment and outcome

Arshad AR, Selvapragasam T

J Craniofac Surg, 2008 Jan;19(1):175-83.

PMID: 18216685 DOI: 10.1097/scs.0b013e3181534a77

This is a study on 124 patients who were treated by the authors over a 19-year period. There were 48 male and 76 female patients. The age range of these patients at the time of treatment was between 4 months and 32 years. There was no family history of similar deformity. All of these patients come from a socially low-income group. Fourteen patients had accompanying congenital amputation of fingers, toes, or limbs. Two had oral cleft lip and palate. The surgical treatment was medial orbital wall osteotomy and excision of encephalocele. There were two mortalities and five patients who had complications that needed secondary surgical intervention. Thirty-eight patients are still under follow up without any complaints.

PMID: 16125400

A vascularized outer-table calvarial bone graft was used for repairing a Posnick type 2 traumatic orbito-frontal bone defect supported by the use of a calcium-based putty (Allomatrix) in a 7-year-old girl. Gaps between the donor and recipient sites were filled with Allomatrix containing demineralized bone matrix particles. Four years later there was a good cosmetic result using an artificial left eye.

Intraorbital foreign body (IOFB) has been a rare phenomenon in the cases of gunshot wounds and always represents a dilemma in medical management. In Sabah, this scenario is becoming common as there is still certain population in the interiors who owns self made guns for hunting. They either present with self inflicted gunshot injuries or after being mistakenly shot while hunting. There are very few articles on this topic especially when it is located posteriorly in the orbit and occurs without visual impairment. This case reports the challenges faced in the management of the patient with a posteriorly located metallic IOFB. The appropriate management of the patient is discussed based on several international literatures. Author describes a 37 years old male farmer, who was referred from a nearby district hospital after he sustained gunshot injuries to his face and scalp. Urgent computed tomography (CT) scan showed that bullet pellets were at the left orbital floor, the left mandible and the left frontal bone. All bullet pellets were located extracranially only without intracranial involvement. Patient clinically does not have any neurologic deficit and without any visual impairment, thus he refused any surgical intervention. As there is no proper guideline in managing such cases, decision was made based on evidences from international literatures. It was concluded that metallic IOFB located in the posterior orbit may be conservatively managed with observation and regular follow-ups as they are well-tolerated and does not cause much impact on visual deterioration unless inflammation, infection, optic neuropathy or functional deficit occurs. This avoids unnecessary surgery and prevents risk of iatrogenic injury to the eye.
