Giant osteoma is a rare entity in the head and neck region when compared to long bones. Even in the head and neck region, the paranasal sinuses are commonly associated, but the involvement of jaw bones is very rare. The lesions are usually asymptomatic and so remain undiagnosed for years. In the reported case, the distinct presentation with reduced mouth opening made it more confusing to diagnose as it became somewhat similar to symptoms of temporo-mandibular joint disorder. The involvement of the zygomatic bone with its extension into the mandibular ramus region made it more unique in its presentation. The objective of the current article is to present an unusual case of giant osteoma of zygoma causing reduced mouth opening, misdiagnosed as a true intra-articular temporo-mandibular joint ankylosis previously. This was then diagnosed correctly with help of a computed tomography scan and histopathology and treated with surgical excision.

Chronic osteomyelitis of the skull base is a commonly reported pathology in existing scientific literature, but chronic osteomyelitis of the skull vault (COSV) is a rarely documented disease. We report the case of a 38 years old Afghan male with a presenting complaint of irregular swelling on the skull vault for six months. The patient had a history of head trauma one year back with a compound depressed fracture which had been surgically managed then.

Article Synopsis
- - Osteomas are the most frequent benign tumors found in the sinonasal area and are often discovered incidentally during unrelated imaging studies; larger versions over 30 mm are termed "giant" osteomas and can lead to complications if they invade nearby spaces.
- - This report details a case involving a 30-year-old woman with a 45 mm fronto-ethmoidal osteoma causing pressure on her eye and frontal lobe, requiring a specialized surgical team of ENT and neurosurgeons for treatment.
- - The goal of treating giant sinonasal osteomas is complete surgical removal through a combined approach, and while the risk of recurrence exists, outcomes can vary based on the surgical methods used.

A patient in his 20s presented with a change in the appearance of his left eye with evidence of relative afferent pupillary defect. Imaging revealed a giant frontoethmoidal osteoma, a benign sinonasal tumour, invading three-quarters of the orbit. Multidisciplinary discussion involving opthalmology, maxillofacial surgery, neurosurgery and otolaryngology resulted in the decision to attempt entirely endoscopic excision of this lesion, which was performed with successful outcomes.

Temporal bone osteomas comprise 0.1-1% of benign tumors involving the skull, the majority of which arise in the external auditory canal. More rarely, they can arise from the mastoid portion of the temporal bone.
