Levator anguli oris muscle based flaps for nasal reconstruction following resection of nasal skin tumours
Adel Denewer, Omar Farouk, Tamer Fady, Fayez Shahatto
World Journal of Surgical Oncology , 2011, DOI: 10.1186/1477-7819-9-23
Abstract: Ninety patients of malignant nasal skin tumours were included in this study. Age was ranged from four to 78 years. For small unilateral defects affecting only one side ala nasi, levator anguli oris myocautaneous (LAOMC) flap was used in 45 patients. For unilateral compound loss of skin and mucus membrane, levator anguli oris myocautaneous mucosal (LAOMCM) flap was used in 23 patients. Very large defects; bilateral either LAOMC or LAOMCM flaps combined with forehead glabellar flaps were used to reconstruct the defect in 22 patients.Wound dehiscence was the commonest complication. Minor complications, in the form of haematoma and minor flap loss were managed conservatively. Partial flap loss was encountered in 6 patients with relatively larger tumours or diabetic co-morbidity, three of whom were required operative re-intervention in the form of debridement and flap refashioning, while total flap loss was not occurred at all.Immediate nasal reconstruction for nasal skin and mucosal tumours with levator anguli oris muscle based flaps (LAOMC, LAOMCM) is feasible and spares the patient the psychic trauma due to organ loss.The skin is the most common site of cancer development in humans. More than one million new skin cancer cases are diagnosed in the United States annually, compared with about 1.3 million cases of all other types of cancer combined. Therefore, skin cancers constituted fully one-half of all cancers diagnosed [1].The nose, being exposed to sun light, is a common site for skin malignancy. Surgical excision remains the best tool for management of skin tumors affecting nasal skin, reconstruction of defects caused by excisional surgery have been done using many techniques including median and paramedian forehead flaps [2], Rhombic bilobed flap, and other advancement flaps [3].The modern era of nasal reconstruction has brought significant advancements and offers unparalleled opportunities for reconstructive surgeons to maximize functional and aesthetic outcomes

Abstract: Iatrogenic vestibular stenosis is a blockage of the nasal vestibule caused by adisruption of the vestibular lining with secondary proliferation of fibrous tissue scar and granulation. It is more common as a result of foreign body reaction or nasal trauma. The lesions usually include the lobby and the anterior inferior turbinate. We report the case of a girl of eleven, with a complete and recurrent stenosis of the right nasal vestibule, and whose history was spent in the incubator at birth and feeding tube during this period with repeated aspirations traumatic nostril.
Nasal Vestibular Huge Keratoacanthoma: An Unusual Site  [PDF]

Pakistan Journal of Biological Sciences , 2009,
Abstract: Keratoacanthoma (KA) is a rapidly growing, low-grade neoplasm of pilo-sebaceous and hair follicle units which most often appears on the sun-exposed skin of the middle aged and older persons with multiple or localized occurrence. This tumor is dome-shaped nodule with a central keratinous plug. The etiology of this tumor is not obvious. Exposure to excessive sunlight is the most frequently noted responsible factor in the etiology of KA. About 80% of the tumors occur on the face. The histological features of the KA are often very similar to those of a cutaneous squamous cell carcinoma; however, the tumor structure usually provides a basis for their difference. There are many unusual cases of keratoacanthoma reported regarding site, size or other specifications. In this study, we excised a mass of nasal vestibule, a site far away sun-exposure. To our knowledge, this is the first case of nasal vestibular keratoacanthoma. For a clinician and a pathologist it is important to consider a benign lesion like Keratoacanthoma (KA) in the differential diagnosis of ulcerated nasal lesions and pay attention to differ it from Squamous Cell Carcinoma (SCC ) which has a different and aggressive management.

Abstract: This report presents a novel style of placing nasal stents. Patientsundergoing surgical procedures in the region of nasal vestibuleand nasal valves are at risk of developing vestibular stenosis andlifelong problems with the external and internal nasal valves;sequels of the repair. The objective of the report is to demonstratea simple and successful method of an inverted V- Stent placementto prevent potential complication of vestibular stenosis and nasalvalve compromise later in life. Following a fall on a sharp edge ofa metallic bed, a sixteen month old child with a deep laceratednasal wound extending from the collumellar base toward thetip of the nose underwent surgical exploration and repair of thenasal vestibule and nasal cavity. A soft silicone stent fashioned asinverted V was placed bilaterally. The child made a remarkablerecovery with no evidence of vestibular stenosis or nasal valveabnormalities. In patients with nasal trauma involving the nasalvestibule and internal and external nasal valves stent placementavoids sequels, adhesions, contractures, synechia vestibularstenosis and fibrosis involving these anatomical structures.The advantages of the described V- stents over the traditionalreadymade ridged nasal stents, tubing’s and composite aural graftsare: a) technical simplicity of use, b) safety, c) less morbidity, d)more comfortable, and e) economical. To our knowledge, this isthe first report of such a stent for prevention of vestibular stenosisand preserving nasal valves.
Post-stenotic aortic dilatation
Emma Wilton, Marjan Jahangiri
Journal of Cardiothoracic Surgery , 2006, DOI: 10.1186/1749-8090-1-7
Abstract: The aetiology of post-stenotic aortic dilatation remains controversial. It may be due to haemodynamic factors caused by a stenotic valve, involving high velocity and turbulent flow downstream of the stenosis, or due to intrinsic pathology of the aortic wall. This may involve an abnormality in the process of extracellular matrix remodelling in the aortic wall including inadequate synthesis, degradation and transport of extracellular matrix proteins.This article reviews the aetiology, pathology and management of patients with post-stenotic aortic dilatation.An English literature search using Pubmed-Medline database between 1960 and today was carried out. Key words used included aortic valve, aortic stenosis, aortic dilatation, bicuspid aortic valve, surgery and matrix metalloproteinase.Aortic stenosis (AS) is the most common valvular heart disease affecting up to 4% of the elderly population [1,2]. Post-stenotic aortic dilatation is defined as dilatation of the vessel wall distal to the area of a partial stenosis. It refers to dilatation of the ascending aorta, >4.0 cm, distal to a stenotic/malformed aortic valve (AV). This dilatation is usually progressive > 0.3 cm/year.Aortic dilatation is thought to be a precursor to aortic dissection and rupture, both of which are potentially fatal.Post-stenotic aortic dilatation has been shown to occur in patients with AS/aortic regurgitation (AR), haemodynamically normal bicuspid aortic valve (BAV) and following aortic valve replacement (AVR). It does not appear to be related to the degree of AS [3], although this study was conducted on patients with a valve area < 2.0 cm2, and appears to be independent of whether the patient has had valve replacement [4]. This suggests a possible genetic basis for the dilatation as well as the mechanical stresses placed on the vessel wall downstream of a stenotic lesion.BAV is an independent risk factor for both AS and progressive aortic dilatation [5].Aortic stenosis is the most common valvula
Cancrum oris among Nigerian children

Nigerian Journal of Surgical Research , 2004,
Abstract: Background: Cancrum oris is a serious health and social problem in developing societies. A retrospective review of Cancrum Oris patients seen in ABUTH over a ten- year period was done to determine the predisposing factors and management. Method: Data was obtained from patient’s case notes, theatre records and clinic notes. Results: 252 patients were seen during the period under review. The highest incidence occurred in the 3-6 year age group. There was no significant sex difference in presentation. The predisposing factors were large family size, low socioeconomic status, poor nutritional status and childhood diseases especially measles and malaria. There was a seasonal variation, with the disease occurring most often during the dry season. The Hausa-Fulani ethnic groups were more commonly affected. Cancrum oris caused both soft and bony tissue destruction in 90% of patients and affected both mandible and maxilla resulting in bony ankylosis. There is an apparent reduction in mortality due probably to the advent of potent antibiotics. Conclusion: Poor oral hygiene, malnutrition, debilitating diseases (such as HIV/AIDS) and lack of maternal care have been identified as predisposing factors to the development of the disease. Health education and economic empowerment are still required in order to curb the menace of this devastating disease.

Abstract: The objective of this clinic based retrospective study was to review the trends in the incidence of cancrum oris at the Dental clinic of the University College Hospital, Ibadan, Nigeria. Records of children aged 1 to 16 years diagnosed as having cancrum oris between 1st of January 1986 to 31st December, 2000 were reviewed. Of the six thousand three hundred and ninety (6390) children seen within the period of study, 45 had cancrum oris with the modal age been 3-5 years and the mean age was 4.2 ± 2.7 years. There was a declining trend in the proportion of children presenting with the disease at five yearly interval within the period of study, although malnutrition was still a common factor in all the children.

Abstract: The paper presents a calculation of the maximal concentration of nitrogen oxides in the vicinity of point sources (main chimneys) of power plants Vojany EVO1 and EVO2. The wind velocity u10,M (7), at which the concentration on a given place in the surrounding of the pollution source attains a maximal value, is calculated. The relation (8) for a calculation of the place with the maximal concentration for a given class of air stability (Table 1 and 2) and for a given wind velocity is derived. According to equation (3) and Table 3, a thermal capacity of EVO1 and EVO2 is calculated, considering a flat country in the vicinity of the sources (x3 = 0 in relation (1)). Subsequently, it is also considered that the wind direction has the direction joining the source and the place of concentration calculation (x2 = 0). The calculations of concentration are performed for the 5th class of air stability. As to this class, favourable conditions for the pollutants dispersion are there. Thus, the maximum concentration is in a relatively small distance from the source with a sharp concentration maximum. As to other classes of the air stability (Table 1 and 2), the maximum concentration is located in larger distances from the source, i.e. about 10 km, as it is considered in Table 4 and 5. The theoretical calculation of NOX concentration in the vicinity of the sources, EVO1 and EVO2, shows (Table 4 and 5) that it does not exceed the allowable limit of 150 μg.m-3.
