Is it necessary to use the angular artery to feed the scapular tip when preparing a latissimus dorsi osteomyocutaneous flap?: case report.

This report demonstrates the possibility of elevation of the scapular tip with the latissimus dorsi muscle based on the thoracodorsal artery only, when an additional and substantial amount of bone is required for complex reconstruction. The patient was a 37-year-old man who developed an epidermoid carcinoma arising from the left maxillary sinus. After wide excision and radical resection of the tumor and the invaded structures, an osteomyocutaneous latissimus dorsi flap was prepared. With the muscle, the 12th rib was included in the flap to reconstruct the orbital floor and zygomatic arch, and the scapular tip was also elevated to reconstruct the hard palate. The skin island over the muscle was designed according to reconstructive requirements, including the buccal lining, nasal lateral wall lining, and coverage of the scapular tip at its new location to reconstruct the hard palate. All of these structures were successfully reconstructed with a single pedicle branch arising from the thoracodorsal artery. Postoperative early and late bone scans showed living bone at the zygomatic arch and hard palate.

Evaluation of velopharyngeal insufficiency with magnetic resonance imaging and nasoendoscopy.

Several radiological methods have been utilized to assess velopharyngeal function. The more recent imaging technique, magnetic resonance imaging (MRI), which has a number of advantages over radiographic and computed tomographic imaging, has been used rarely for evaluating velopharyngeal insufficiency. In this study, 5 normal volunteers and 10 patients with surgically repaired cleft palate were examined with MRI using midsagittal, coronal, and axial images. Nasoendoscopy was also performed to complete and confirm the diagnoses. Complete and tight closure of the velopharynx and full backward and upward movement of the soft palate was observed in volunteers. In coronal images, medial movement of lateral pharyngeal walls could also be seen. Despite this, patients with surgically repaired cleft palate had some degree of motion of the soft palate, ranging from no movement to maximal movement. In most of the patients, short soft palates with restricted motion was seen. MRI visualizes the velopharyngeal sphincter in all planes and provides high-resolution images of the soft tissues. Objective measurements can be made as well. In this study, MRI and nasoendoscopy were used together in the diagnosis of velopharyngeal insufficiency and gave satisfactory results.

Unilateral virginal breast hypertrophy.

A case of unilateral virginal breast hypertrophy with a review of the etiological factors and treatment modalities is presented. A 16-year-old girl presented with progressive enlargement of the left breast of 5 months' duration. The result of the mammographic examination was consistent with cystosarcoma phyllodes. Fine-needle aspiration biopsy revealed giant fibroadenoma. Although some of the characteristics of the fine-needle aspiration biopsy specimen were suspicious for cystosarcoma phyllodes, there were no adequate epithelial structures, which are obligatory for the diagnosis. The patient was treated with subcutaneous mastectomy and subpectoral insertion of a silicone gel implant. The histopathological examination was consistent with virginal hypertrophy. The breast maintained its volume with no further growth in the affected or in the normal breast after 4 years of follow-up.

Bilateral congenital pits of the upper lip.

Congenital sinuses, fistulas, dimples, or pits of the lips are uncommon congenital malformations. In the upper lip they are extremely rare, and only one third of them are placed laterally. The authors present a patient with bilaterally placed upper lip pits associated with speech disorders, a short and everted upper lip with an orbicularis muscle defect in the midline, slight hypertelorism, and low-set ears. Orbicularis muscle repair and tubercle augmentation were performed. No further treatment was administered to the upper lip pits because of lack of symptoms. This is the third bilateral case of the sinus or pit of the upper lip reported in the literature.

The effect of onlay Medpor implants on mandibular growth in young rabbits: an experimental study.

Medpor implants were placed on the periosteum of the mandible in infant rabbits to study their effects on growth. Three months later radiological and histopathological studies were performed in situ and after removal of the mandible. The authors demonstrate that implants did not affect normal development of the mandible; however, there was a decrease in bone thickness and a mononuclear cell reaction was caused where the implant came in contact with the bone.

Evaluation of soft-tissue morphology of the face in 1,050 young adults.

Anthropometry of the face has always been an interesting subject for artists and plastic surgeons. Since ancient times, many rules have been proposed for the ideal face. The authors measured directly vertical and horizontal proportions of the face and inclinations of the soft-tissue facial profile in 1050 young Turkish adults. Differences between the facial measurements of subjects from seven different geographic regions were analyzed. Some of the measurements were compared further with the measurements of other populations in the literature, and the validity of the neoclassical canons were tested. The special head height measure was shorter than the special face height in the majority of our study group (women/men: equal height, 13%/15%; longer special head height, 28%/30%; shorter special head height, 59%/55%). Faces with three equally high-profile sections were not seen in women or in men. When the forehead height was compared with the nose height, equality was present in a small percentage of the population (women/men: equal height, 17%/18%; longer forehead, 41%/ 42%; shorter forehead, 42%/40%). The nose height was equal to the lower face height in a minority of the population (women/men: equal height, 10%/11%; longer nose, 9%/11%; shorter nose (81%/78%). The forehead height was shorter than the lower face height in the majority of the population (women/ men: equal height, 8%/9%; longer forehead, 12%/13%; shorter forehead, 79%/78%). The intercanthal distance was shorter than the nose width in the majority of the population (women/men: equal width, 20%/19%; wider intercanthal distance, 35%/37%; narrower intercanthal width, 65%/68%). The population was distributed evenly in regard to the variations of the orbital proportion canon (women/men: equal intercanthal width and eye fissure length, 31%/36%; wider intercanthal distance, 34%/27%; narrower intercanthal width, 35%/37%). The mouth width was greater than 1.5 times the nose width in the majority of the population (women/men: equal width, 6%/5%; wider mouth, 53%/54%; narrower mouth, 41%/41%). The nose width was narrower than one quarter of the face width in the majority of the population (women/men: equal width, 4%/3%; wider nose, 30%/39%; narrower nose, 66%/58%). The nose inclination was equal to the ear inclination in a very small fraction of subjects (women/ men: equal inclination, 3%/3%; greater nose inclination, 88%/87%; less nose inclination, 9%/9%). To sketch an outline of the average facial profile in the population studied, a convex facial profile is revealed, with the forehead and the chin retrodisplaced minimally with respect to the midface. The neoclassical canons were found to be invalid for the majority of the population in this study, and different proportional analytic results were obtained.

Malignant melanoma in xeroderma pigmentosum patients: report of five cases.

Xeroderma pigmentosum is a rare genetic disease transmitted via a recessive gene with an altered reaction of the epidermis to light. Fifty per cent of patients develop a skin tumour by 8 years of age. The majority of patients may have multiple tumours, but metastasis is rare. In the last 25 years we have treated 24 xeroderma pigmentosum patients in our clinic. Only five patients had developed cutaneous malignant melanoma during their follow-up. Three of the patients were from the same family, melanoma occurring in three of five affected individuals. All xeroderma pigmentosum patients with malignant melanoma had received classical treatment modalities. Except one case of fulminant pattern, all four patients had long disease-free survival. Although early detection and treatment of these cutaneous malignancies will reduce morbidity and mortality, genetic counselling remains the most important protective measure for xeroderma pigmentosum.

Metastatic malignant blue nevus: a case report.

This report presents a 63-year-old Caucasian woman with a malignant blue nevus, which is an extremely rare form of melanoma originating from or associated with a preexisting blue nevus. The background blue nevus on the left upper arm, which had been present for 5 to 6 years, increased in size and darkened in color for 3 months prior to histological diagnosis of malignant blue nevus. Although the tumor looked much like a nodular melanoma clinically, the diagnosis of malignant blue nevus was established histologically. The patient had a poor outcome due to metastatic spread of the tumor to the visceral organs 1 year following the initial excision of the tumor. To distinguish this rare tumor from other melanocytic lesions, strict histological criteria are needed to make the diagnosis of malignant blue nevus. Differential diagnosis includes cellular blue nevus, atypical cellular blue nevus, primary malignant melanoma, and metastatic melanoma to the dermis. Malignant blue nevus is most commonly seen on the scalp. The tumor has an aggressive behavior and metastasizes in the majority of patients. This paper describes the second reported case of malignant blue nevus involving the upper arm. Clinical and histological features of this uncommon tumor are presented, along with a review of the literature.

A case of popliteal pterygium treated along with nerve expansion.

The presence of a short sciatic nerve in the free edge of a popliteal pterygium makes this syndrome a surgical challenge. We present a case of popliteal pterygium that was treated by nerve expansion. The range of motion of the patient's knee joint was between 30 and 120 degrees. A 75-cc tissue expander was placed under the sciatic nerve and filled with 5 cc of saline solution weekly. When a total of 60 cc was reached, wound dehiscence was observed, and the procedure had to be stopped. The maximum extension obtained was 160 degrees. Since the expansion process had to be stopped early, the elongation attained by expansion was less than expected. We conclude that the nerve expansion method can be used as a good alternative treatment modality for patients with popliteal pterygium.

A technique for the repair of simple congenital earlobe clefts.

Congenital cleft of the earlobes is rarely seen among congenital ear anomalies. These clefts show a wide range of severity and localization, from simple notching to extensive tissue deficiencies. We developed a new technique that can be used in simple cases of earlobe cleft. For this technique, we use the anterior and posterior parts of the cleft as Y-V advancement flaps and achieve a three-dimensional construction of the lobe that is symmetrical with the opposite lobe.
