Review
BACKGROUND
Cranial osteomas are regarded by some as very common; yet their classification, symptomatology, and management have been neglected.
METHODS
We report on a giant enostotic convexity osteoma and have reviewed the medical literature.
RESULTS
A new comprehensive classification for cranial osteomas is proposed: (1) intraparenchymal, (2) dural, (3) skull base, and (4) skull vault. The latter is in turn, subdivided into exostotic and enostotic variants. Three symptom producing enostotic convexity osteomas have been reported in the world literature. We also describe a giant enostotic skull vault osteoma and propose an original surgical technique used to successfully resect this unusual tumor.
CONCLUSIONS
Most cranial osteomas are asymptomatic and need not be resected. Those that are symptomatic should be managed properly. Their excision, if nor properly performed, may lead to unforeseen cerebral complications.

Review
Osteomas are benign lesions composed of mature compact and/or cancellous bone that grow continuously. Their pathogenesis is unknown. It has been considered to be a neoplasm, a developmental or reactive osteogenic lesion resulting from muscle traction on the periosteum, or due to trauma. Herein, we report an unusual case of giant osteoma of the mandible depressing the lateral pharyngeal wall, interfering with normal respiration during the night. The uniqueness of this case is related to snoring and sleep apnoea symptoms. In fact, he presented to our Department because daytime sleepiness hindered his work, and not for the evident facial swelling. We reported our experience in diagnosis, treatment and follow-up of this uncommon disease. Polysomnography, CT scan and 3-D PAS volume analysis are useful tools to study in detail the aetiology of apnoea and assess outcomes.

OBJECTIVE
Osteomas are slow-growing benign tumors that can affect the skull, most frequently the parietal and frontal. Temporal bone osteomas are more common in the external acoustic meatus and exceptional in the mastoid region. The rarity of mastoid osteomas is confirmed by the fact that very few cases have been reported in the clinical and paleopathological literature. The aim of this paper is to report a new paleopathological case of mastoid tumor in a Pre-Hispanic adult cranium.
MATERIALS
The skull derives from the Chunchuri (today Dupont-1 site) Pre-Hispanic site in Northern Chile (1390 A.D).
METHODS
Macroscopical examination and high-resolution tomography were used to assess the cranium.
RESULTS
The CT scan revealed a well demarcated lesion suggestive of a mastoid osteoma.
CONCLUSIONS
This case adds new evidence regarding the antiquity of primary neoplasms in ancient populations and reinforces the importance of high resolution imaging in paleopathological research.
SIGNIFICANCE
Due to the antiquity of the remains this is probably the oldest reported case of mastoid osteoma.
LIMITATIONS
The patrimonial nature of the remains did not allow histopathological studies.
SUGGESTIONS FOR FURTHER RESEARCH
Further intensive review of archeological skeletal collections is needed to better understand the epidemiology of neoplastic lesions in past populations.

The present study investigates a circumscribed bony overgrowth on the cranial vault, known as button osteoma (BtO) and referred to here as button lesion (BtL). We discuss its anthropological implications. Data on its histology, location, and population distribution (by age, race, and gender) are provided. Microscopically, BtL is composed of well-organized dense lamellated bone which is poorly vascularized and with very few osteocytes. It forms a dome-shaped roof over an underlying diploeized area which includes the ectocranial table. The frequency of BtL is similar in modern (37.6%) and archaeological (41.1%) populations, in blacks, whites, males, and females, and correlates with age. It is rare in nonhuman primates. Fifty-five percent of the human skulls studied by us had BtL only on the parietal, 23.6% on the frontal, and 3.6% on the occipital bones. Fifteen percent had BtL on both the frontal and parietal bones. No lateral preference was found. Most skulls with BtL (64.1%) had only one lesion, 20.4% had two BtL, and 15.4% demonstrated multiple BtL. The average number of button osteomas on an affected skull was 1.97. The frequency of large osteomas (0.5-1.0 cm) was similar in young and old age groups. The demographic characteristics of BtL, mainly its high frequency among ancient and modern populations, its independence of sex and race, its scarcity in other primates, and the fact that its macro- and microstruture are indicative of an hamartoma (and not an osteoma or exostosis) suggest an evolutionary background to the phenomenon.

American Journal of Rhinology & Allergy 2013This study was designed to investigate the clinical features and the growth rate of craniofacial osteomas.
BACKGROUND
This study was designed to investigate the clinical features and the growth rate of craniofacial osteomas.
METHODS
Retrospective chart review was performed of 200 cases of craniofacial osteomas diagnosed from January 2001 to September 2011. Data pertinent to patient and osteoma lesion characteristics were collected. Histology of operated cases was reviewed. Computer tomography (CT) charts were reviewed and those with multiple images were analyzed for growth characteristics.
RESULTS
One hundred forty-nine patients met our inclusion criteria. Eighty-nine percent of these osteomas were found incidentally. Forty-three percent were in the frontal sinus. Fifteen percent of the patients complained of headaches and only 6.71% of patients with osteoma had headaches congruent with osteoma location. Thirty-one percent of CT scans had sinus mucosal disease; only 8% had mucosal disease adjacent to the osteoma. Ten of the 149 patients underwent surgery for cosmetic and/or rapidly growing osteomas. Thirteen patients had intestinal tubular adenoma, and one was genetically positive for Gardner's syndrome. Fifty-two patients had multiple CT scans that were included in growth rate analysis. The mean linear growth rate of osteomas was estimated to be 0.117 mm/yr (95% CI, 0.004, 0.230) in maximal dimension, assuming linear growth. A descriptive analysis of osteoma growth divided the osteomas into several intervals and studied the growth rate separately in each interval. The median change in maximum dimension was different in each interval in a nonsystematic manner, ranging from -0.066 mm, over 3- to 9-month interval (interquartile range [IQR] = -0.404-1.069), to 0.369 mm over 9- to 15-month interval (IQR = -0.032-0.855), and 0.082 mm over 45- to 51-month interval (IQR = -0.000-0.197). There was no significant association between tumor size, location, or complications.
CONCLUSION
Craniofacial osteomas are slow-growing lesions with no specific growth pattern and rare complications. Their clinical behavior is ill defined and justifies a conservative approach toward asymptomatic lesions with close radiological follow-up.

INTRODUCTION
Osteomas are benign bone tumors with a slow progressive growth. These lesions are predominantly located in craniofacial sinuses, but other locations including mandible have been described. Their etiopathogenesis remains controversial. We report a case of post-trauma mandibular osteoma. Gardner syndrome was ruled out.
OBSERVATION
A 31-year-old female patient consulted for a peri-mandibular swelling present for the previous two years. On radiological examination, a bone sclerotic lesion was observed, located on the right lower mandibular edge. Patient history documented an initial trauma at the lesion site. Surgery was performed and anatomopathological examination confirmed the diagnosis of compact osteoma. There was no recurrence one year after surgery.
DISCUSSION
The etiopathogenesis of osteomas is controversial and several hypotheses are suggested. It is regarded as a true benign tumoral process, or abnormality of development, or as a reaction to trauma or infection. The development of osteoma after trauma has been described in several cases, notably in mandibular locations exposed to shocks (angle and lower edge). Multiple osteomas must mandatorily lead to screening for a Gardner's syndrome, because of the associated risk of colon cancer.

Osteomas of the middle ear are rare lesions. We report the case of a 20-year-old male with osteoma originating from the promontory coincident with tympanic membrane perforation. Histopathological diagnosis was performed by means of a superficial curettage during surgery, to avoid a cochlear fenestration. Postoperative closure of the air-bone gap after myringoplasty confirmed the presumed asymptomatic nature of these lesions.

A 57-year-old man presented with an extremely rare osteoma originating from the left L-5 inferior articular process and causing lumbo-crural sciatica. Postmyelography computed tomography and magnetic resonance imaging showed an osteoma compressing the spinal nerve root at the lateral recess. Decompression facetectomy and excision of the lesion followed by transforaminal lumbar interbody fusion between L-5 and S-1 provided complete relief from the symptoms. Histological examination confirmed the diagnosis of benign osteoma. The previous seven cases of spinal osteoma involved the vertebral body, pedicle and posterior elements. Spinal osteomas should be considered in the differential diagnosis of benign lesion originating from the articular process.

Review
Intracranial subaural osteomas without any relation to osseous or meningeal tissues are rare, with only five cases including the present one having been reported so far. In most patients headache, which was always localized at the site of the lesion, was the most frequent complaint and subsided after complete resection of the neoplasm. The mechanism of origin of such lesions remains unknown.
