Background: Neurofibroma is a major facial hamartoma and is one of the most destructive and debilitating disease affecting the skin, muscle, mucosa, and the skeletal systems. Involvement of the ear usually increases the dimensions of the auricular skin and underlying tissues, distorts normal architecture along with auricular malpositioning, producing an ear that is abnormal in size, shape and position. The correction of the auricle in neurofibroma and benign tumors of the head and neck has been reported, but overall favorable results appear difficult to attain. We present a case of neurofibroma of the auricle in which radical resection was performed, and reconstruction was done in a two-stage surgery with satisfactory result. Patient and Methods: A 30 years-old female presented with type-1 neurofibroma to our office, especially concerned of a large tumor growth on the right auricle. With prior experience in treating microtia cases by Nagata’s method, we performed a two-stage operation on the patient. The first operation involved excising the whole auricular mass, and fabricating as well as grafting of a three-dimensional costal cartilage framework. In the second stage, the ear was elevated.Result: Nine months after the second surgery, the result was satisfactory with good auricular definition attained, and proper elevation of the ear at the correct anatomical site. No sign of neurofibroma recurrence was found on the surrounding reconstructed auricle.Summary: In our experience, the correction Neurofibroma of the ear by using the aggressive tumor removal principle combined with Nagata’s two-stage total ear reconstruction delivered a satisfactory result.

Varying degrees of congenital ear deformity (microtia) occurs 1 in about 8000 to 10,000 live births. One of the greatest challenges in plastic surgery is total auricular reconstruction as it demands precise technique as well as artistic creativity. In Bangladesh, recent advancement in the technique of carving and sculpting rib cartilage  and better training for achieving finer anatomic details has given a break through in the surgical management of  deformed ear. Between January 2009 and January 2010, total ear reconstruction was done with a two-stage method using  autogenous costal cartilage in the Department of Plastic Surgery, Dhaka Medical College Hospital, Dhaka. In the first stage, lobule rotation, fabrication of the cartilage framework and its implantation were performed. In  the second stage, elevation of the auricle and formation of the tragus were done. A total of 10 cases with microtia comprising different age group have been operated. All of them underwent stage I operation; among them 8 patients went through stage II procedure while the other 2 are waiting for the same. Results: 10 patients, ranging in age between 8 and 25 years, were operated on using autogenous costal cartilage between 2009 and 2010. Six patients were males and four were females. Unilateral microtia was present in all of these patients (7 right, 3 left). Eight cases were with Grade III microtia; the remaining 2 cases presented with Grade II microtia. The follow-up period was one month to one year. Seven among 8 cases presented acceptable ear contour after second stage ear reconstruction. The cranioauricular angle of the reconstructed ears was also similar to that of the opposite ears. Unfavourable result was deformation of the constructed helix which occurred in one case. Though it is impossible to reconstruct an ear that appears exactly as the opposite one, the new ears which were  made were of correct size and in normal position with impressive finer three dimensional details that achieved patient’s satisfaction as well as surgeon’s professional gratification.Key words: Microtia; Two stage auricular reconstruction; Autologous costochondral cartilageBDJPS 2010; 1(2): 14-19

✓ The authors report five cases of surgically treated giant vertebral artery aneurysm. Two giant serpentine aneurysms were managed with aneurysmectomy, a giant semifusiform aneurysm with trapping and partial aneurysmectomy, and the other two saccular giant aneurysms with clipping. Surgical results were satisfactory in all cases. In particular, the two patients who underwent complete aneurysmectomy showed remarkable improvement after the second procedure of a two-stage operation that consisted of initial proximal occlusion and secondary evacuation of clots in the aneurysm when advanced thrombosis was identified. Aneurysmectomy in a two-stage operation was the best treatment for these partially thrombosed giant aneurysms which completely concealed the distal artery under a tight thinned medulla.

We are studying the crystallization and annealing behavior of high performance polymers, like poly(p-pheny1ene sulfide) PPS, and poly-(etheretherketone), PEEK. Our purpose is to determine whether PPS, which is similar in many ways to PEEK, undergoes reorganization during annealing. In an effort to address the issue of reorganization, we are studying solution grown single crystals of PPS as model materials.Observation of solution grown PPS crystals has been reported. Even from dilute solution, embrionic spherulites and aggregates were formed. We observe that these morphologies result when solutions containing uncrystallized polymer are cooled. To obtain samples of uniform single crystals, we have used two-stage self seeding and solution replacement techniques.
