The status of ulcerated lesion was assessed by intra-oral and extra oral clinical evaluation and panoramic or
occipitomental radiograph.
Investigations like pure tone audiogram, X-Ray mastoids (Lateral oblique view), X-Ray paranasal sinuses (
occipitomental view) and complete haemogram were done.
X-ray para-nasal sinus (PNS) (
occipitomental view) and X-ray (chest posterior anterior view) were also done.
Chest X-ray was normal and
occipitomental (Waters' view) X-ray was consistent with sinusitis.
In all the patients, open mouth Water's view was performed in routine with chin elevated and in
occipitomental plane, while the chin and nose were in contact with the x-ray film.
X-ray (
occipitomental view) of the paranasal sinuses showed haziness of all the sinuses and mucosal thickening of the maxillary sinuses, more so on the left.
This projection also is referred to the
occipitomental view and is considered the best overall view for the orbits, orbital rim structures, orbital floor, maxillary and frontal sinuses, zygomatic arches, nasal arches and septum.
Radiological Finding:
Occipitomental view of X-ray PNS showed homogenous opacity of almost whole of right side of face.
Occlusal, panoramic,
occipitomental or lateral radiographs can be used, although CT-scan is the powerful and useful technique, because it provides an exact and anatomical location.4,6 Clinically, the patient may be asymptomatic or has symptoms as swelling, pain, limitation of mandibular movements or trismus, if fibrosis is present.4
All patients underwent a thorough nasal examination and radiographic evaluation with standard x-rays, including Waters' (
occipitomental) and lateral views of the nasal bones and paranasal sinuses.
X ray lateral cephalometric and
occipitomental views were performed.
Zygomatic bone fractures are also known as isolated zygomatic fracture, molar fracture or classic tripod fracture.31 However, the terms tripod fracture and trimolar frac-ture are inaccurate and should be avoided because zygoma has four processes rather than three and it can be fractured at single process only.24 In this study 88% of the zygomatic bone fractures were diagnosed and confirmed using
occipitomental view.
