Sphenochoanal polyps in Singapore: diagnosis and current management.

Sphenochoanal polyp is a rare form of choanal polyp. If unrecognised, they can be mistaken for an antrochoanal polyp. This will result in unnecessary exploration of the maxillary sinus, and a failure to remove the sphenoidal component of the sphenochoanal polyp. Adequate preoperative evaluation with computed tomography or magnetic resonance is mandatory to ascertain the correct diagnosis, and to facilitate the planning of the appropriate surgical procedure. We present two patients with sphenochoanal polyp and a review of the literature.

The glossopharyngeal nerve, glossopharyngeal neuralgia and the Eagle's syndrome--current concepts and management.

Glossopharyngeal neuralgia is not just a painful condition. At times, it may be life-threatening as a result of associated cardiovascular consequences. Even in the absence of life-threatening consequences, it can be a severe debilitating disease with depression, suicidal tendencies, fear of swallowing, loss of weight and under-nutrition. The treatment for glossopharyngeal neuralgia and Eagle's syndrome has evolved over time. This review summarises the scientific evidence and philosophy about current management and therapy. Emphasis is placed on the importance of excluding secondary causes of glossopharyngeal neuralgia before embarking on nerve section through the posterior cranial fossa approach. The Eagle's syndrome due to an elongated styloid process is the most important cause of secondary glossopharyngeal neuralgia. Stylectomy is effective and should be considered before embarking on any neurosurgical procedure. Peripheral cervical and trans-tonsillar approaches to the glossopharyngeal nerve are also discussed.

Branchiogenic carcinomas: do they exist?

The existence of branchiogenic carcinomas is questioned in this review, which also discusses the different possibilities in an adult patient who presents with a cystic swelling in the upper lateral aspect of the neck. Most cases of branchiogenic carcinomas reported in the literature may actually have been secondary metastatic lesions from an occult tonsillar carcinoma. We will also discuss the different features of cystic metastasis that distinguish them from solid metastasis, and explain why oropharyngeal carcinomas with cystic neck metastasis should be in a separate category from other head and neck cancers.

Job analysis, appraisal and performance assessments of a surgeon--a multifaceted approach.

The role of a surgeon is a complex one. A variety of skills and abilities in a different array of performance tasks is required before he can be competent in his job. As such, there is no simple rule of thumb that can be used to assess a surgeon's performance. As performance assessment and appraisal become increasingly important both for manpower decisions and personal development, it is important that we recognise the different roles a surgeon plays. Only then are we able to subdivide a surgeon's job demands into small manageable portions for analysis. This paper examines the multi-faceted aspects of a surgeon's job, and how each facet should be individually assessed and appraised.

Acetowhite staining in the detection of laryngeal disease.

The acetowhite staining reaction is widely used as a reliable adjunct to the diagnosis of malignant lesions in gynaecology, but its application in vocal cord lesions has not been assessed before. The use of the acetic acid staining reaction in selecting sites for sampling on the vocal cord is considered in this study. A 3% acetic acid solution was applied intraoperatively before biopsy to the larynx of eight patients who had either diffuse erythematous or polypoidal vocal cords. Attempts were made to correlate the degree of acetowhitening with the underlying histological findings. There was a very poor correlation between acetowhitening and the histological diagnosis, and very poor demarcation between stained and unstained areas. The application of acetic acid is not a useful adjunct to biopsy selection in the larynx.

Cystic nodal metastasis in occult tonsil carcinoma--a case report.

A "branchial cyst" in a patient above 40 years old may turn out to be a malignant cystic nodal metastasis from a primary tumour in the tonsil. We present a case of a 45-year-old woman in whom an initial mistaken diagnosis of branchial cyst was made. The neck mass was discovered to be malignant and the left tonsil was subsequently implicated as the primary source. Older patients with cystic neck masses should be managed on the presumption that these may possibly be metastatic lesions from a primary oropharyngeal tumour.

Malignant fibrous histiocytomas of the larynx--report of two cases.

Malignant fibrous histiocytoma of the larynx is a rare entity. It is even more infrequent for the tumour to arise from a specific location on the larynx namely the vocal cords. We report two cases of vocal cord malignant fibrous histiocytoma, one in a 27-year old man who underwent frontal partial laryngectomy, and the other in a 57-year old man who was managed with total laryngectomy. Both patients remain disease-free after 5 years of follow-up. We present a discussion of the available literature on this subject. As these tumours occur very infrequently, no one centre is able to acquire the prerequisite amount of experience to be able to lay down firm scientifically based guidelines on the management of these tumours. It is thus inevitable that whatever evidence we have is purely anecdotal in nature.

Congenital absence of incus--a rare abnormality.

A case is described of a nine-year-old girl with a bilateral and symmetrical congenital absence of incus. This very rare abnormality has been described only once previously in the literature. Although the pathology may be rare, treatment is straightforward and prognosis good. A discussion of middle ear embryology and a review of the literature is presented.

Reconstruction of moderate sized intra-oral defects using the nasolabial flap.

The nasolabial flap was used in 11 patients for reconstruction of moderate sized intra-oral defects. There was minimal morbidity of donor and recipient sites in terms of function and cosmesis. The flap was easily harvested, with a reduction in operating time. The superb vascularity and reliability of the flap was demonstrated by the fact that it was possible to use this flap even after a radical neck dissection had been performed on the same side or after radiotherapy. This article describes the authors' experience with the use of the subcutaneously-pedicled, inferiorly-based, double-staged nasolabial flap for intra-oral reconstruction.
