Comparison Between the Superior Pedicle Retro Auricular Flap and the Masson's Revolving Door Flap for Coverage of Conchal Defects.

Post operative defect of the external ear result mainly from the resection of skin cancers of this region, hence the need for an adequate plasty to avoid any stenosis or deformation, this article compares 2 retroauricular flap covering techniques through 2 cases of patients with conchal basal cell carcinoma the first one was a 65 years old male patient who had for 2 years a basal cell carcinoma of the postero-superior part of the concha of the right ear, a total removal of the tumor was made with a successful covering of the substance loss by a retroauricular flap with superior pedicle. The second patient was a 66 years old female who has for 3 years a basal cell carcinoma of the inferior part of the concha of the right ear, a successful removal of the tumor was and the covering of the substance loss by a Masson's retroauricular revolving door flap. We discuss the different operating times as well as the advantages and disadvantages of each technique, to finally conclude that the retro auricular flap is an excellent technique to cover the postoperative loss of substance of the superior part whereas the Masson's revolving door flap is more adapted for the posterior lesions of the concha.

Rare Schwannomas of Head and Neck and Review of Literature.

Benign schwannoma is a slow growing encapsulated tumor arising from the sheath of Schwann, The majority had extra-cranial localization. We report in this review three cases of a rare extra cranial localization of benign schwannoma in the trachea, frontal sinus and intraparotid facial nerve. The first case diagnosed in a 10-years-old boy, presented with a painless, slow growing mass evolving for three years in the left parotidic region, total conservative parotidectomy was done. The second case concerned a 38-years-old, was admitted to the emergency department with acute inspiratory dyspnea, endoscopic exploration revealed a polylobed tracheal tumor, complete tumor excision was done endoscopically. The third case was about a 33 years old patient, presented a gradually enlarging frontal swelling associated with headache and left nasal obstruction, the endoscopic examination revealed a gray pinkish, smooth and firm soft tissue mass occupying the entire left nasal cavity, CT scan and MRI were requested to assess the characteristics and extent of the tumor, The surgical intervention combined two approaches: trans facial through a mid-frontal incision, and endonasal one. Histopathological examination confirmed the diagnosis of benign schwannoma in all these cases.
