Osteoma of the condyle as the cause of limited-mouth opening: a case report

Siar CH, Jalil AA, Ram S, Ng KH

J Oral Sci, 2004 Mar;46(1):51-3.

Osteoma is a benign tumour consisting of mature bone tissue. It is an uncommon lesion that occurs mainly in the bones of the craniofacial complex. Only a few cases involving the condylar process have been reported. An osteoma of the left condyle causing limited mouth-opening in a 32-year-old Malaysian Chinese female is reported here to alert the practitioner to consider this lesion as a diagnostic possibility in instances of trismus or limited-mouth opening.

Mastoid osteoma is a rare benign neoplasm of mesenchymal origin. Osteomas of the temporal bone are
infrequent, and these mastoid osteomas are a definite rare occurrence. These tumours can present with
cosmetic deformity and sometimes with pain. In this report we describe a patient with mastoid osteoma
who presented with cosmetic deformity and experienced retro auricular pain.

Single Port Endoscope-Assisted Excision of Forehead Lesions: An Innovative Way of Improving the Optical Cavity

Exophytic lesions involving the face present with an undesirable esthetic deformity and usually necessitate surgical excision. Conventional open excision techniques may lead to scar formation or pigmentation issues postoperatively. Minimally invasive endoscope-assisted surgery will be able to overcome these problems. However, this technique is not widely used because of the limited optical cavity working space, which hinders good visualization. We describe a technique to improve the optical cavity workspace to enable adequate endoscope-assisted surgical excision of forehead lesions in 2 cases. Foley's catheter and ribbon gauze were used in both cases to gain optical cavity workspace. The surgical technique is described in detail. One case had a frontal osteoma, whereas other was a nodular fasciitis of the forehead, confirmed by histology. Postoperative follow-up showed good outcomes at 1 year with no recurrences. Both patients were satisfied with the surgical and cosmetic outcomes. Endoscopic excision of a forehead lesion using the described technique is both safe and reliable. It is an excellent method for excising benign growths over the forehead while being cosmetically acceptable.

Bone in the eye

Jumaat BH, Dahalan A, Mohamad M

Am J Ophthalmol, 2003 Feb;135(2):254-6.

PMID: 12566045

PURPOSE: To report a case of choroidal osteoma presenting with massive subretinal hemorrhage not associated with choroidal neovascularisation (CNV).

DESIGN: Case report.

METHODS: An 18-year-old man presented with sudden loss of vision in the right eye following competitive swimming. He was found to have a massive subretinal hemorrhage involving the macula.

RESULTS: Following resolution of the hemorrhage, the patient was found to have an underlying choroidal osteoma. There was no evidence of choroidal neovascularisation clinically and angiographically. He regained his normal vision.

CONCLUSIONS: Choroidal osteoma presenting with massive subretinal hemorrhage not associated with underlying choroidal neovascularization need not result in poor visual outcome.

Fulltext Bone Remodeling in Choroidal Osteoma Monitored by Fundus Photography and Spectral-Domain Optical Coherence Tomography

Choroidal osteoma is a benign ossifying tumor of the choroid, consisting of mature bone tissue. It has been described to enlarge and evolve at varying rates over time. Here, we report and quantify the progression of a unilateral choroidal osteoma in a 7-year-old boy by fundus photography, and document tumor remodeling by spectral domain optical coherence tomography images.

Fulltext Epiphora as the primary initial presentation for a huge sino-nasal osteoma: a rare presentation

Nadia Yaacob, Adil Hussein

Journal of Biomedical and Clinical Sciences, 2018;3(2):26-28.

MyJurnal

Sino-nasal osteoma is a common benign tumour of paranasal
sinuses and usually asymptomatic. Here, we presented a case of a huge sinonasal osteoma. Despite the large size of the tumour, the only presentation
was epiphora. There were no headache, facial pain or diplopia. Nasal
obstruction only occurred after involvement of the nasal cavity. In diagnosing
aetiology of the epiphora, sino-nasal pathology needed to be ruled out after
excluding ocular causes. Multidisciplinary approach between otolaryngology
(ORL) team and ophthalmology team was essential in managing the case.
The tumour was successfully removed surgically via endoscopic approach;
and dacryocystorhinostomy (DCR) was performed to alleviate the epiphora.

Osteomas are benign bone tumors which arise from the cortex or medulla of craniofacial and jaw bones. They are usually asymptomatic or present as slow-growing painless masses. Larger lesions may present with aesthetic (facial asymmetry) and functional disturbances (jaw deviation, difficulty in breathing, pain, and sensory deficits). This paper highlights a case of solitary peripheral osteoma composed of a compact bony mass arising from the lower border of the mandible in an adult female patient. The lesion presented with discomfort during deglutition, which was attributed to impingement of muscles of the oral cavity floor, including the anterior belly of digastric muscle.

A rare case of large sphenoethmoidal osteoma

Med J Malaysia, 2017 02;72(1):60-61.

PMID: 28255144 MyJurnal

Osteoma is the most common benign tumour of the nose and paranasal sinuses. However, involvement of the sphenoid sinus by osteoma is rare. Most of the time, patients with paranasal sinus osteoma are asymptomatic. However, symptoms may present, depending on the location and extension of the tumour. We report a case of a patient with sphenoethmoidal osteoma found incidentally on imaging, with evidence of impingement onto the optic nerve at the optic canal. However, the patient was asymptomatic. He was surgically treated using the endoscopic transnasal approach.

Radiofrequency ablation (RFA) therapy is recognised as a safe and effective treatment option for osteoid osteoma. This case report describes a 27-year-old man who underwent computed tomography (CT)-guided percutaneous RFA for a femoral osteoid osteoma, which was diagnosed based on his clinical presentation and CT findings. The patient developed worsening symptoms complicated by osteomyelitis after the procedure. His clinical progression and subsequent MRI findings had led to a revised diagnosis of a Brodie's abscess, which was further supported by the eventual resolution of his symptoms following a combination of antibiotics treatment and surgical irrigations. This case report illustrates the unusual MRI features of osteomyelitis mimicking soft tissue tumours following RFA of a misdiagnosed Brodie's abscess and highlights the importance of a confirmatory histopathological diagnosis for an osteoid osteoma prior to treatment.

Fulltext Endaural approach of external auditory canal osteoma: report of two cases

Osteomas occur in all parts of the temporal bone, including the mastoid, squamous, middle
ear, styloid process, internal auditory canal and external auditory canal (EAC). The EAC has
been reported to be the most common site, followed by the mastoid and squamous parts.
Diagnosis is made based on history, clinical examination and radiological findings. Computed
tomography reveals a pedunculated hyperdense mass that usually arises from the
tympanosquamous suture. Surgical removal of EAC osteomas can be achieved using the
endaural or postauricular approaches. It can be performed with a drill or osteotome, either
endoscopically or by using microscopy. This report presents two patients with EAC osteomas
who underwent excision under microscopy using the endaural approach. Surgery is the gold
standard treatment, while close observation may be considered in asymptomatic patients.
