Oroantral communication is a common sequalae following extraction of maxillary posterior teeth. If it fails to resolve within 48 hours, epithelization of the tract occurs and fistula formation results. It may manifest as nasal regurgitation of fluid during drinking, sinusitis etc. Effective management of the same is required to prevent long term complications. Management strategies ranges from palatal splint, alloplastic materials to buccal advancement flaps, sandwich techniques etc. Effective management requires individualized treatment plan with consideration about size of the fistula, time elapsed, preexisting infection and host defenses. Key words: Oroantral fistula, Cald-wel Luc approach, displaced root, maxillary antrum

Verrucous carcinoma or Ackerman’s tumor is considered a low-grade variant of oral squamous cell carcinoma. It usually occurs on buccal mucosa followed by gingiva, tongue and hard palate. Clinically it manifests as an ulceroproliferative growth with cauliflower like or irregular papillary appearance. Tobacco in any form, alcohol and viral infections from HPV are possible etiologic factors for this type of carcinoma. In this article, we have presented a classic case of verrucous carcinoma in a 39-year-old male with habit of chewing maawa (a form of smokeless tobacco). If left untreated or misdiagnosed, these lesions can transform into oral squamous cell carcinoma. Hence, proper diagnosis at appropriate time is essential for treating the disease, so that the patient is expected to have a salubrious life style.
