Background: To understand the relationship between our bacterial microbiome and health, it is essential to define the microbiome in the absence of disease. The digestive tract includes diverse habitats and hosts the human body’s greatest bacterial density. We describe the bacterial community composition of ten digestive tract sites from more than 200 normal adults enrolled in the Human Microbiome Project, and metagenomically determined metabolic potentials of four representative sites.
Results: The microbiota of these diverse habitats formed four groups based on similar community compositions: buccal mucosa, keratinized gingiva, hard palate; saliva, tongue, tonsils, throat; sub- and supra-gingival plaques; …

Department of Otolaryngology - Head and Neck Surgery Faculty Papers
Osteomas, the most common skull tumors, are typically excised through either an open or endoscopic ostectomy using a high-speed drill, a technically challenging procedure that can result in injury to adjacent soft tissue structures. Osteoma removal through ultrasonic bone emulsification and aspiration (UBA) offers the advantages of decreased blood loss, preservation of adjacent soft tissue structures, and precise bone removal. UBA was used to successfully remove a forehead osteoma without injury to adjacent nerves and with a satisfactory cosmetic outcome. We describe skull osteoma removal with an ultrasonic bone aspirator, which offers potential advantages over conventional bone removal techniques.

Section of Otolaryngology, Head & Neck Surgery
Primary hyperparathyroidism is a common condition with surgery being the definitive treatment modality. Controversy exists over the extent of optimal neck exploration, whether unilateral or bilateral exploration should be performed, particularly since 85-90% of primary hyperparathyroidism results from single gland disease. Unilateral neck exploration is now considered to be adequate unless a definitive adenoma is not identified on ipsilateral exploration and where the serum intact Parathyroid Hormone (iPTH) level does not show a decline greater than 60% after removal of a suspected adenoma. It also avoids the potential risk of hypocalcaemia, recurrent laryngeal nerve injury along with extended anaesthesia and …

Laryngeal Tuberculosis Presenting As Laryngeal Carcinoma, Anwar Suhail, Muhammad Sheharyar Ahmed, Zain-Ul-Abdeen Sobani, Shahzad Ghaffar
Section of Otolaryngology, Head & Neck Surgery
Tuberculosis (TB) accounts for the highest number of mortalities among infectious diseases worldwide. Laryngeal TB is an extremely rare presentation of TB. It has many similarities to laryngeal carcinoma, one of the three most common cancers among males in the city, with an age standardized rate of 8.6. The associated risk factors of laryngeal carcinoma i.e. smoking, paan, betel nut usage and alcohol use also tend to be concentrated in the same demographic background as that of TB, creating a diagnostic dilemma. We present a case of granulomatous laryngeal TB, in a 40 year old male, with characteristic presenting features …

Adult Laryngeal Haemangioma; A Rare Entity, Shabbir Akhtar, Adeel Ahmed Shamim, Shehzad Ghaffar, Muhammad Sheryar Ahmed, Mubasher Ikram
Section of Otolaryngology, Head & Neck Surgery
Laryngeal haemangioma is commonly seen in children. Adult laryngeal haemangiomas are rare and usually involve the supraglottic region. Most common symptom includes dysphagia, dysphonia and shortness of breath. Detailed history, fiberoptic laryngoscopy and computerized scanning may suggest benign nature of the lesion but diagnosis is only confirmed by a biopsy. In comparison to infantile haemangiomas which usually respond to propronolol, the treatment of adult laryngeal haemangiomas is always surgical removal. We present a case report of a supraglottic haemangioma in an adult male, who was treated surgically without any complications.

Section of Otolaryngology, Head & Neck Surgery
Encephaloceles are anomalous herniations of the meninges, with or without brain matter. Globally the incidence of encephalocele is about 1 per 35,000 births, but it is more frequently reported in Southeast Asia. As the defect is more pertinent to embryological development, an encephalocele is a more common entity in an infant with a mean age of presentation ranging between 15.5 and 21 months; making an encephalocele presenting for the first time in a relatively, older individual a rare occurrence. Consequently a surgeon might not consider an encephalocele among his differentials. Here we present a series of encephaloceles that presented at …

Neuronavigation Assisted Endoscopic Sinus Surgery, Masaud Mohyuddin, Zain A Sobani, Montasir Junaid, Shehzad Ghaffar
Section of Otolaryngology, Head & Neck Surgery
In the past two decades, endoscopic sinus surgeries (ESS) have been widely advocated as a safe and effective treatment for disorders of paranasal sinuses that are refractory to medical therapy. ESS caters surgeons with two-dimensional visualization of the anatomical structures; however in scenarios where there is a close anatomical relation between the disease and delicate intracranial or intraorbital structures drastic complications can occur. Hence, endoscopic procedures had to be converted into open surgical procedures if the extent of the disease could not be visualized or cleared thoroughly. Recently however; neuronavigation systems have been combined with ESS to yield better results …

Section of Otolaryngology, Head & Neck Surgery
OBJECTIVES: Squamous cell carcinoma of the oral cavity has a profound impact on a patient's nutritional intake, 40-50% of head and neck cancer patients have a markedly impaired nutritional status at the time of their initial presentation. Studies show that patients who have better nutritional status have fewer complications and a better survival rate. Therefore, enteral nutritional support plays an important part in their management. Due to the lack of relevant data, surgeons help patients make informed decisions regarding their mode of nutritional support and perform gastrostomy or place nasogastric tube depending on the patient's preference. This study addresses the …

Mucoepidermoid Carcinoma Of The Base Of Tongue, Zain-Ul-Abedeen Sobani, Montasir Junaid, Shehzad Ghaffar, Anwar Suhail
Section of Otolaryngology, Head & Neck Surgery
Mucoepidermoid carcinomas are thought to arise from the reserve cells of salivary gland ducts. Minor salivary glands are located all around the oral cavity and base of the tongue; however few cases of MEC of the base of the tongue have been reported in literature and no guidelines are available for its management. Here we would like to present the case of a 71 year old male with mucoepidermoid carcinoma of the base of the tongue successfully treated with surgical excision and neck dissection. Regular clinical follow up showed no signs of recurrence at 9 months post excision.

Tp53 As A Biomarker In Head And Neck Squamous Cell Carcinoma, Thomas J. Ow Md
Dissertations and Theses (Open Access)
Currently, there are no molecular biomarkers that guide treatment decisions for patients with head and neck squamous cell carcinoma (HNSCC). Several retrospective studies have evaluated TP53 in HNSCC, and results have suggested that specific mutations are associated with poor outcome. However, there exists heterogeneity among these studies in the site and stage of disease of the patients reviewed, the treatments rendered, and methods of evaluating TP53 mutation. Thus, it remains unclear as to which patients and in which clinical settings TP53 mutation is most useful in predicting treatment failure.
In the current study, we reviewed the records of a cohort …
