1 of 2 DESCRIPTION A man presented with a 1-year history of a progressively worsening penile skin lesion. Over the preceding 2 months, he reported passage of urine from two distinct exit points on the distal penis. There were associated low grade penile pain, dysuria, spraying of urine on micturition, daytime urinary frequency, nocturia of three, the sensation of incomplete bladder emptying and...

Hypospadias is a congenital malformation of the male external genitalia, which includes: anomalous location proximal to urethral meatus, in any portion glans penis and perineum, hooded dorsal foreskin, inverted penile curvature on side foreskin. The etiology has been considered multifactorial, secondary interaction environmental factors with specific genetic background. It represents second mos...

INTRODUCTION Melanoma is a malignant tumor that can affect any area of the anatomical economy. Its occurance in the female urethra is extremely rare. We report a case of primary malignant urethral melanoma developed in an elderly female patient. PRESENTATION OF CASE A 70 years old female presented with dysuria, poor stream, gross haematuria, intermittent blood spots, and a painful mass. On ph...

Bilateral dissections of maxilla were performed in a human adult cadaver head, male, aged 53 years. After the en block removal of the soft tissues in the oral and infraorbital regions, the antero-lateral surface of maxilla was exposed and also the vestibular aspect of the upper alveolar process. An oblique labially impacted right upper canine was evidenced, completely submucosal: its apex was t...

Urethral prolapse is a disease of prepubertal black girls and postmenopausal women with an unknown cause. It may be congenital in origin or an acquired condition. It has never been reported in males. We report a 10-year-old Caucasian boy who presented because of recurrent right undescended testis. He had been operated on for bilateral undescended testes 7 years ago in another hospital, and circ...

OBJECTIVE We sought to assess the complication rates following cochlear implantation in canal wall down mastoid cavities in adults and children. DATA SOURCES A systematic review of English articles from PubMed, Web of Science, EMBASE, and the Cochrane Library. Additional studies were identified by reviewing the reference lists of the originally identified studies. REVIEW METHODS Studies wer...

The tympanic membrane in mammals is a trilaminar structure formed by the apposition of two epithelial cell layers, along with an intervening layer of cells derived from pharyngeal arch mesenchyme. One epithelial layer is contributed by the external acoustic meatus, a derivative of the first pharyngeal cleft. The other epithelial layer is contributed by the tubotympanic recess, a derivative of t...

A knowledge of the external ear and tympanic membrane is essential to practicing audiologists. This article provides an introduction to the anatomy of this area including dimensions, orientation, vasculature, innervation, and relations to other structures. Traditional diagrams are often inadequate in describing these structures. For example, typical frontal and sagittal views of the external au...

BACKGROUND AND PURPOSE Total correction of proximal hypospadias and penoscrotal transposition (PST) is a challenge to surgeons. Staged operation is usually recommended because the blood supply to the neourethra or the skin covering the penile shaft may be severed during scrotoplasty. This paper describes results obtained using a new technique for total correction, which preserves the blood supp...
