Effectiveness of the supraomohyoid neck dissection in clinically N0 neck patients with squamous cell carcinoma of buccal mucosa and gingivobuccal sulcus
. J Int Soc Prev Community Dent.
 The gingivobuccal complex is composed of the buccal mucosa, gingivobuccal sulcus
, lower gingiva of mandibular alveolus, upper gingiva of maxillary alveolus and retromolar trigone area.
Among the tobacco chewers, all of them used piper betel leaf smeared with slaked lime (called chunnamb colloquially in Kerala) and areca nut and dried tobacco as a quid for keeping on either gingivobuccal sulcus
. History of irradiation was present in eight cases and 10 cases were recurrences, mainly in glottis, nasopharynx, hypopharynx, and oral cavity.
After an incision was made on the right gingivobuccal sulcus
, the buccal mucoperiosteal flap was elevated.
Areas of fibrosis were scored 2 for each area--soft palate including uvula, right or left anterior faucial pillar including tonsil, right or left buccal mucosa including gingivobuccal sulcus
, right or left retromolar trigone, tongue or floor of mouth.
Patients were discharged within a few days with only minor analgesics since they experienced minimal discomfort owing to the absence of surgical incisions in the nasal septum, palate or gingivobuccal sulcus
Scale made of tobacco quid deposited on teeth and gum junction causes Periodontitis and Carcinoma of lower gingivobuccal sulcus
. While on upper gingivobuccal sulcus
, same can occur but is less common.
The sites of involvement in the oral cavity were oral tongue in five patients, alveolus in two, gingivobuccal sulcus
in one, and hard palate in one.
The mass had caused a bulge in the soft palate and gingivobuccal sulcus
If not infected it is painless swelling, typically appear as a swelling at canine fossa, gingivobuccal sulcus
elevating ala of nose.
Medially, the growth had reached the midline; laterally, it involved the right gingivobuccal sulcus
; anteriorly, it involved the alveolus up to the central incisors; posteriorly, it extended just anterior to the retromolar trigone but did not involve it.
In the left gingivobuccal sulcus
there was a 7x4 cm sub mucosal proliferative lesion involving the retromolar trigone area and the adjacent buccal mucosa with scattered ulcerated areas which was indurated and mildly tender (Figure 1).
