37. Acute maxillary sinusitis This is a common complication of a head cold. Apical infection of the teeth related to the antrum, or oro-antral fistula following dental extraction also cause maxillary sinusitis, as may trauma with bleeding into the antrum, or barotrauma. Frontal or facial pain may be referred to the upper teeth. Nasal obstruction and purulent rhinorrhoea are the other symptoms. The antrum is opaque on X-ray and dull on transillumination. There may be tenderness over the sinus but swelling is rare. Pus is seen issuing from the middle meatus.

40. Dental sinusitis The apices of the molar teeth may be extremely close to the antral mucosal lining. The upper wisdom tooth apparent on this X-ray, if infected, would be likely to cause maxillary sinusitis or, if removed, would be clearly at risk to cause an oro-antral fistula.

61. Torus palatinus The bony hard midline palatal swelling can be diagnosed confidently by its characteristics. It is a common finding and only requires removal if it interferes with the fitting of a denture. A large torus palatinus may take on a curious irregular appearance, suspicious of a carcinoma.

65. Malignant nasal tumours A nasal polyp that does not appear grey and opalescent should arouse suspicion, as should a polyp that bleeds spontaneously. Granulation tissue in the nose may be malignant granuloma or carcinoma, and biopsy of any suspicious nasal lesion is necessary. A pigmented polyp may be a malignant melanoma.

66. Carcinoma of the antrum or ethmoid These may extend not only into the nasal fossa and cheek but may present in the oral cavity appearing as a dental lesion. The antrum is opaque on X-ray with evidence of bony destruction Prognosis when radiotherapy is followed by maxillectomy is quite good for an early maxillary carcinoma, but poor when there is extensive invasion. Exenteration of the orbit with maxillectomy is necessary when the eye is involved, but carcinoma with posterior spread to the base of the skull is inoperable. The use of cytotoxic drugs results in regression in some of these paranasal sinus neoplasms and is a further line of treatment. Extension of a neoplasm superiorly into the anterior cranial fossa involves resection superiorly of the dura and involved frontal lobe of the brain in continuity with the nasal and sinus neoplasm (cranio-facial resection).

83. Lip ulcers Lip ulceration has numerous causes, either traumatic, inflammatory, or neoplastic: the provisional diagnosis can be made from the history and type of ulcer. Biopsy is necessary to confirm the diagnosis. The lesion is a pyogenic granuloma. Although these lesions are frequently small and related to trauma, they may enlarge from secondary infection and take several weeks to heal. secondary infection

The vesicular type of skin eruption is confined to the distribution of the nerve. The ophthalmic division of V is most frequently involved, but all three divisions of V are rarely affected at the same time. mandibular division maxillary division

97. Minor salivary gland tumor A palatal swelling which is not bony and hard may be a cyst if midline, but if placed to one side, it is almost certainly a tumour of one of the minor salivary glands. Biopsy is necessary.
