1/4. Recurrent buccal space abscesses: a complication of Crohn's disease.Oral features of Crohn's disease include ulcerations, lip fissuring, cobblestone plaques, and mucosal tags. We report the case of a 16-year old male patient with a 3-month history of abdominal pain, diarrhea, and oral ulceration. Clinical examinations revealed established intestinal lesions, a marked cobblestone appearance in the oral cavity, and an unusual pattern of presentation not previously reported in the literature: persistent, recurrent buccal space abscesses.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
2/4. Submental cutaneous sinus tract as a result of progressive peri-implantitis: a case report.BACKGROUND: The aim of the present case report was to define diagnosis and treatment options of a submental cutaneous sinus tract as a result of a progressive peri-implantitis around mandibular dental implants in a patient with a history of oral squamous cell carcinoma. methods: Before the removal of the submental fistula, a panoramic radiograph and a computed tomography of the head and neck were assessed to identify the implants responsible for the cutaneous sinus tract and to exclude the presence of a tumor recurrence and lymph node metastases. The involved implants were removed, as there was a communication along them between the oral cavity and the cutaneous sinus tract resulting from progressive peri-implantitis. A histological examination of the excised fistula was carried out. RESULTS: The histological examination excluded a recurrence of the oral squamous cell carcinoma. The fistula completely consisted of granulation tissue without epithelialization. After affected implants were removed, the wound healing was uneventful. CONCLUSIONS: A panoramic radiograph is mandatory to identify the involved implants. Computed tomography, and excision of the fistula and a histological examination should be performed only in patients with a history of oral squamous cell carcinoma. Since the cutaneous sinus tract showed no epithelialization, it healed spontaneously after the removal of the responsible implants. Because of the large bony defect caused by progressive peri-implantitis leading to a communication of the oral cavity with the cutaneous sinus tract, more conservative treatment options with preservation of the implants could not be adopted in the present case.- - - - - - - - - - ranking = 2keywords = oral cavity, cavity (Clic here for more details about this article) |
3/4. cleft palate fistula closure with a mucosal prelaminated lateral upper arm flap.BACKGROUND: Recurrent cleft palate fistula is a challenge for maxillofacial surgeons. In severe cases, microvascular tissue transfer is necessary to treat these patients successfully. methods: A 23-year-old man with cleft lip and palate, previously treated elsewhere, presented with a 2-cm defect in the posterior hard palate. A tongue flap had already been performed. It was decided to close the persistent fistula with a lateral upper-arm flap. In a first-step operation, a free graft of buccal mucosa was fixed to the lateral upper arm subcutaneously and covered with an alloplastic sheet. After 11 weeks, the prelaminated flap was harvested and transferred to the palate. RESULTS: Integration of the buccal mucosa to the upper arm was uneventful. On harvesting the flap, we found a smooth, thin, and continuous fasciomucosal flap with a mucosa surface of 4 x 4 cm. Healing of the microvascular flap in its recipient site was regular. The fistula was closed successfully. CONCLUSIONS: To the authors' knowledge, this is the first report of a lateral upper-arm flap prelaminated with autologous mucosa. By prelamination, it is possible to circumvent the disadvantage of extraoral skin within the oral cavity and to cover mucosal defects with mucosa, especially in elective procedures, such as cleft cases.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
4/4. Rhinolithiasis as cause of oronasal fistula.Rhinolithiasis is a disease caused by deposition of organic and inorganic compounds in the nasal cavity, leading to unilateral nasal obstruction, fetid rhinorrhea, epistaxis, and it may cause complications. The authors present a case of rhinolithiasis with oronasal fistula and literature review.- - - - - - - - - - ranking = 0.048431178101681keywords = cavity (Clic here for more details about this article) |
