Osteoma of the temporal bone squama: a case report and review of literature

BackgroundOsteomas are benign slow-growing tumors, which typically arise on the surface of the bone. They rarely arise from the temporal bone, accounting for 0.1–1% of all benign tumors of the skull. The external auditory canal (EAC) is the most common site for osteomas in the temporal bone. Other extra-canalicular osteomas of the temporal bone are uncommon and infrequently reported. In this case report, we discuss the clinical presentation and surgical management of osteoma of the squamous part of the temporal bone. A limited review of literature is also presented.Case presentationA 20-year-old male presented to the outpatient department (OPD) with a chief complaint of a hard swelling above his left ear, for 4 years. He had no other complaints other than cosmetic concern. On examination, there was a solitary, smooth, bony hard swelling just antero-superior to the left pinna, and the overlying skin was unremarkable. The left EAC and tympanic membrane were normal. A non-contrast computed tomography (CT) scan of the head and face with 3-D reconstruction showed a16 × 18 mm exophytic, pedunculated bony lesion arising from the squamous part of the temporal bone suggestive of an osteoma. The patient was taken up for surgical excision under general anesthesia. The bony lesion was removed from its attachment to the skull using a gouge and a mallet. The base of the tumor was drilled using a polishing burr to ensure complete removal and prevent recurrence. The histopathology was confirmatory of compact osteoma. Postoperative period was uneventful, and follow-up at 18-month post-surgery did not reveal any recurrence clinically.ConclusionOsteoma of the temporal squama is rarely reported, and surgical excision is the definitive treatment if symptomatic. This case report highlights the surgical management of this rare tumor. A limited review of literature suggests that squamous part of the temporal bone is an unusual site for extra-canalicular osteomas, and the prognosis is good after surgery.

Surgical treatment of extensive peripheral osteoma in the mandibular ramus: Case report

Osteomas are benign osteogenic tumors, which clinically manifest as well-defined and asymptomatic lesions. This article aims to report a case of extensive osteoma in the mandibular branch, addressing the main tools used for diagnosis and treatment modalities. Patient L.M.S, 55 years old, male, sought the service of Maxillofacial Surgery, reporting the appearance of a nodule on the face with evolution of 2 years. On physical examination, a significant volumetric increase was observed in the pre-auricular region on the left side, asymptomatic on palpation and non-bleeding. Computed tomography was requested, which showed a hyperdense bone lesion in the mandibular ramus region. The planned surgical proposal was for extra-oral access in the pre-auricular region on the left side, excision of the lesion by osteotomy followed by osteoplasty for the regularization of the remaining bone tissue and suture by planes. Subsequently, the piece was sent for histopathological analysis that identified the lesion as a compact osteoma. The patient was followed up for 1 and a half years, through clinical and radiographic evaluation, through which an excellent bone repair was observed, with no signs of recurrence. Carrying out the clink exam is essential for the diagnosis of osteoma, as it is an asymptomatic pathology. Due to the fact that it has a low probability of recurrence and does not present malignancy, a conservative approach can be performed with the appropriate postoperative follow-up. Therefore, it is concluded that the performance of a thorough clinical examination associated with the imaging and microscopic information are essential for a good clinical management of this pathology.

Case study of giant frontal-ethmoid sinus osteoma

Aim: The authors hereby present a case of giant frontal-ethmoid sinus osteoma which is not so rare but in the present case, the size and orbital involvement of this tumor make it a unique case. Introduction: Paranasal sinus osteoma most commonly presents in frontal sinuses. Their growth is slow, and patients usually seek physician’s advice only for cosmetic reasons. Case Description: A 20-year-old female presented to us with the complaint of proptosis of left eye near medial canthus for last 6 months. After investigations, she was diagnosed with frontal-ethmoid sinus osteoma, which was excised by endoscopic approach. There was dense, compact bone and broad trabeculae of mature bone i.e. compact osteoma which was confirmed on histopathology. Conclusion: Paranasal sinus osteomas are slow-growing bony tumors, which are amenable to complete cure provided adequate preoperative planning and conscientious surgical technique is used.

Compact osteoma of the maxilla: A rare case report

Osteomas of the facial bones are a rare entity and very few cases have been reported in the literature. Osteoma is a benign osteogenic lesion with a very slow growth, characterized by proliferation of either cancellous or compact bone. This paper describes a case of a 27 year old male seeking treatment for a slowly enlarging lesion in the maxillary right anterior region. Surgical excision of the lesion was done and the histopathologic evaluation revealed dense compact bone with osteocytes in the lacunae suggestive of compact osteoma. One year followup showed no evidence of recurrence. To best of our knowledge this is the twelfth case of maxillary osteoma reported in English language literature.

Inferior turbinate neoplasms

The main aim of the work was to describe a rare clinical case of osteoma of inferior turbinate. The interest of the case is that such tumors are extremely rare. A female patient of 63 years old attended an ENT clinic. She complained on absence of nasal breath at the right side and headache. After a full ENT-examination, anamnesis, and a thorough analysis of the radiation examination results (computed tomography data), a decision was made to surgical treatment. Under general anesthesia, controlled hypotension surgery was done. First step was septoplasty, then the dense bone tumor was reduced and removed. At the control examination in 3 months, the complete removal of the formation of the inferior turbinate on the right is determined. There were no signs of continued or recurrent tumor growth. Neoplasms of the nasal cavity, in particular the inferior turbinate, are extremely rare pathologies. They are mainly detected when performing anterior rhinoscopy, endoscopic examination of the nasal cavity. The result of histological examination is compact osteoma. The gigantic size of the inferior turbinate osteoma in our case is probably due to the patient's failure to consult a specialist (otorhinolaryngologist) for a long time. Surgical treatment of this pathology should consist in an endoscopic endonasal approach: this approach allows the most complete and minimally traumatic removal of the tumor.

Наблюдение больной с одновременным нахождением в лобной пазухе остеомы и мукоцеле

The article presents a clinical case of successful treatment of a patient with an osteoma and mucocele in her left frontal sinus, with the development of intraocular complications: diplopia, exophthalmos, ptosis of the upper eyelid, restriction of the movement of the eyeball. After a thorough examination of the patient, consultations with an ophthalmologist, neurologist and CT scan and diagnosis, the patient underwent a frontotomy under endotracheal anesthesia. During the opening of the frontal sinus, a U-shaped periosteal flap was preserved, which is used later for plastic surgery of a postoperative bone defect. Under video endoscopic control, the membrane and contents of the mucocele and osteoma were removed, and the frontal-nasal anastomosis was controlled and expanded. The bone defect in the anterior wall of the frontal sinus was removed by alloplasty with a simulated polytetrafluoroethylene (ecoflon) plate fixed with a U-shaped periosteum graft. As a result of the operation, almost all intraocular complications were successfully eliminated. Histological examination of the material removed from the sinus confirmed the presence of a compact osteoma and chronically inflamed mucosa. This clinical observation is of interest in the rarity of simultaneously finding an osteoma and a mucocele in the frontal sinus, and the possibility of mucocele formation due to obstruction of the fronto-nasal anastomosis with an osteoma. The possibility of one of the methods for alloplasty of a bone defect is presented.

Idiopathic Mastoid Osteoma

In this case report, we describe the rare case of an idiopathic mastoid osteoma. A 40 year old woman complained of tenderness over her right mastoid during exercise and changes in head position. Medical treatment was initially offered with topical corticosteroids, capsaicin, and conservative cervical physical therapy. When her symptoms did not ameliorate, surgical management was then offered. Appropriate surgical planning included computed tomography with threedimensional reconstructions. A mastoidectomy through a postauricular incision for resection was then performed. The osteoma was then removed en bloc with final pathology consistent with a benign compact osteoma of the right mastoid.

再発した下顎骨周辺性骨腫の1例

Osteoma is non-odontogenic tumor occurring mainly in the skull and jaw bones. We reported a rare case of recurrent peripheral osteoma of the mandible after a prolonged period.The patient was a 46-year-old woman with a chief complaint of swelling at the right mandibular angle. Ten years ago, she underwent surgery in another hospital. The operation involved excision of peripheral compact osteoma in the same region. This time, there was a localized hard mass. Computed tomography showed a mass measuring about 24 × 24 × 10 mm. We excised the tumor intraorally under general anesthesia. The histopathological diagnosis was compact osteoma. There has been no sign of local recurrence during a follow-up period of 2 years.

下顎下縁部に発生した周辺性骨腫の1例

We report a rare case of a peripheral osteoma involving the inferior border of the mandible. The patient was a 59-year-old woman who presented to the hospital because of swelling of the left jaw and facial asymmetry. She had noticed the swelling 13 years earlier. A bone-like mass lesion measuring approximately 35 × 30 mm was observed in the subcutis at the inferior border of the left side of the mandible. Panoramic radiography showed a bone-like mass arising in the inferior border of the left side of the mandible. Computed tomography also showed a well-defined, lobular bone-like lesion with homogeneous density connected to the mandible. The clinical diagnosis was peripheral osteoma. Surgical resection of the lesion was performed extraorally with the patient under general anesthesia, and the histopathological diagnosis was peripheral compact osteoma. No recurrence has been detected postoperatively.

関節突起部に生じた周辺性骨腫の1例

Osteoma is a benign tumor consisting of mature bone tissue. A solitary osteoma is classified as peripheral when it arises from the periosteum, central when it arises from the endosteum, and extraskeletal when it arises in soft tissue. Solitary osteomas occur mainly in the craniofacial bones. Peripheral osteomas arising in the condylar process of the mandible are rare. Here, we report a case of peripheral osteoma of the condylar process in a 62-year-old woman who complained of a cosmetic disturbance. The osteoma, 48 X 43 X 37 mm in a diameter, was surgically excised by a submandibular approach. The histopathological diagnosis was a compact osteoma. The patient remains free of recurrence after 1 year.

下顎枝内側にみられた周辺性骨腫の１例

Osteoma often occurs in the skull and facial bones, but rares arises in the mandibular ramus. We report a case of peripheral osteoma arising inside the mandibular ramus. The patient was a 37-year-old man who had spontaneous pain at the right parotid region. The tumor was resected extraorally. The pathological specimen showed compact osteoma.

右下顎骨体部と下顎枝に発生した周辺性骨腫の１例

Ostema occurs mainly in the skull and facial bones and only rarely arises in the mandible. A rare case of a large peripheral ostema of the mandible is reported. A 46-year-old woman was referred to our hospital because of painless hard masses in the right side of the mandible. She had no symptoms except for facial asymmetry. Radiographic examination revealed two well-circumscribed, dense, radiopaque lesions in the left mandibular body and ramus. The masses, measuring 45×30 mm and 55 × 33 mm, were removed surgically via a submandibular approach under general anesthesia. The histopathological diagnosis was compact osteoma. The patient has been followed up for 5 years and has shown no tumor recurrence. This case is very rare with respect to location and size.

下顎骨に発生した周辺性骨腫の１症例

A case of peripheral osteoma occurred in the mandible of a 73-year-old woman is presented. The patient had not noticed the mass in the left mandible until we pointed it out. Radiographic examination revealed a forefinger-sized, dense and radiopaque mass which protruded from the lateral surface of the left mandible. The mass was removed surgically. The removed tumor measured about 15×15×18mm and its surface was smooth and glossy like the bone. The histopathological diagnosis was a compact osteoma. Such cases are rarely reported in the literature. The patient had no evidence of recurrence at five years follow-up after operation.

Osteoma in mandibular condyle

A case of peripheral osteoma occurring in the mandibular ramus in a 26-year-old man is reported. Radiographic examination revealed a pedunculated, protruding globular, bone-like opaque mass around the notch of the right mandibular ramus. Histopathological examination showed a lamellar bone structure with irregular arrangement. Wide trabeculae, narrow interstitial areas, and many fibrovascular channels were detected by scanning electron microscopy. Thus, characteristic findings of a compact osteoma were obtained clinically and histopathologically.

Orbital Osteoma in Gardner's Syndrome

A 30-year-old woman developed proptosis secondary to a left ethmoidal compact osteoma. At age 29 years, a mandibular eburnated (ivory) osteoma was excised. At age 25 years, multiple adenomatous polyps of the colon were resected. Her father, age 61 years, had multiple intestinal polyps and bilateral mandibular osteoma. A 24-year-old sister had an osteoma of the forehead. Gardner's syndrome is an autosomal dominantly inherited disorder characterized by intestinal polyposis, various skin and soft tissue tumors, and osteomas of the bony skeleton. Orbital osteomas occur rarely.

OSTEOMA OF THE MASTOID: REPORT OF A CASE WITH AN INVESTIGATION OF THE CONSTITUTIONAL BACKGROUND

In November 1936 I had occasion to diagnose a tumor of the mastoid process which was proved histologically to be a compact osteoma. On account of the uncommon occurrence of osteomas in this region it was decided to investigate this case and the subject in general as thoroughly as possible. A survey of the literature on the subject has been made and is published in order to review certain facts which have enabled me to submit a classification of such tumors and to suggest a cause for some of them. It is necessary to state that the term osteoma as used in this paper refers to a benign, circumscribed, usually slow growing tumor of bony tissue and that only such a tumor affecting the mastoid process of the temporal bone is to be particularly considered. Osteomas assume various formations, and as a result certain terms such as hyperostosis, exostosis, endostosis
