Left sinus pyriform fistula treated by minimally invasive approach: A case report.

INTRODUCTION: Abnormalities of the fourth branchial arch are less common than those of the second arch and usually present with inflammation of the left thyroid lobe. CASE PRESENTATION: We report the case of a 10 years old girl who presented to our department with recurrent cervical cellulitis, and who was diagnosed, upon endoscopic exploration, with a left sinus pyriform fistula. The patient was treated using mini-invasive surgery by electrocoagulation, with good clinical outcome. CONCLUSION: Branchial arch malformations are rare congenital malformations. The diagnosis is mainly based on clinical examination, imaging and, endoscopic investigations. The conservative attitude may be the treatment of choice, especially if the cervical mass is not well individualized.

Intraparotid facial nerve plexiform neurofibroma in a child (case report).

BACKGROUND: Intraparotid facial nerve neurofibromas are benign neoplasms, extremely rare, difficult to diagnose and to manage. Only three pediatric cases have been reported in the literature. CASE PRESENTATION: We report the 4th case of a 7-year-old child admitted for a parotid mass without facial palsy, for whom the surgical indication was the increase in volume of this mass, as well as the aesthetical impairment, the surgical exploration found the tumor attached to the lower branch of the division of the facial nerve. The excision of the mass was performed with the sacrifice of the inferior branch of the facial nerve, the trunk and the upper branch of the facial nerve was preserved, the pathological study was in favor of a plexiform neurofibroma.The patient has presented postoperatively a grade 5 facial palsy in the inferior territory of the facial nerve with a slight recovery 1 year after surgery. CONCLUSION: Even though plexiform neurofibromas in the parotid gland are extremely rare, and their diagnosis are not often primary evoked in front of any growing mass of this region, the surgeon must keep in mind the existence of these neoplasms as a differential diagnosis of a parotid tumor.

Bezold's abscess: An extremely rare complication of suppurative mastoiditis: Case report and literature review.

INTRODUCTION: Bezold abscess is a suppurative complication of mastoiditis that the incidence has significantly decreased in the current era due to the introduction of antibiotics. PRESENTATION OF CASE: We discuss the case of a 62-year-old male who developed Bezold abscess following a right mastoiditis. He presented with laterocervical swelling. His management included; incision and drainage of the abscesses; and mastoidectomy. CONCLUSION: The incidence of Bezold abscess appears to be increasing, perhaps due to ignorance of the disease by many clinicians, and diagnosis is often delayed with potentially fatal consequences.
