Retro-auricular endo assisted selective neck dissection (how I do it).

Elective neck dissection (END) is preferred in all treatment naïve patients with invasive oral squamous cell carcinoma (OSCC), including the early stage, node negative cases (T1/T2 N0). Usually the conventional horizontal neck crease incision leads to a faintly visible scar in the neck. However sometimes, the neck scar is hypertrophic and is highly unaesthetic and psychologically distressing to the patient.

Short message service prompted mouth self-examination in oral cancer patients as an alternative to frequent hospital-based surveillance.

Introduction: Oral squamous cell carcinoma (OSCC) are amongst commonest cancer in the Indian sub-continent. After treatment, these patients require frequent followup to look for recurrences/second primary. Mouth Self Examination (MSE) has a great potential in all levels of prevention of oral cancer.

Oral squamous cell carcinoma associated with oral submucous fibrosis have better oncologic outcome than those without.

Objective: Oral submucous fibrosis (OSMF) is a potentially malignant disorder associated with the use of areca nut, and is mainly seen in the parts of Southeast Asia and the Indian subcontinent. We hypothesized that oral cancers occurring in presence of OSMF are clinicopathologically a distinct entity.

Study Design: We analyzed 289 treatment naïve patients of oral cancer.

A Novel Obturator Device for Management of Dilated Trachea-esophageal Puncture Tract Fistulas.

Voice rehabilitation in laryngectomized patients by tracheoesophageal puncture is a time tested technique. In some patients the tracheoesophageal puncture gets inordinately dilated leading to leakage around the prosthesis. Most of these fistulas are managed by a variety of conservative treatments like temporary removal of prosthesis, placement of silastic ring over the prosthesis, placement of nasogastric tube and airway protection by a cuffed tracheostomy tube.

Recurrent ameloblastoma in temporal fossa: A diagnostic dilemma.

Ameloblastoma is a unique, histologically benign but aggressive neoplasm of the jaws, arising from odontogenic epithelium with potency to cause extensive destruction of jaw bones and infiltration into the surrounding tissues. Recurrences are common after incomplete treatment. Recurrences can occur at difficult sites such as temporal and infratemporal fossa, orbit, anterior cranial base, paranasal sinuses etc.

Can metastatic lymph node ratio (LNR) predict survival in oral cavity cancer patients?

Objectives: To evaluate the prognostic role of the lymph node ratio (LNR; ratio of total positive nodes to total dissected nodes) in oral squamous cell carcinoma (OSCC) as compared to pN staging with an aim to provide an optimal cut-off value.

Methods: 1,408 OSCC previously untreated patients who underwent treatment (surgery + neck dissection + adjuvant treatment). LNR sensitivity with respect to survival was calculated using receiver operating characteristic (ROC) curves and Cox regression method.

Osteosarcoma of the mandible mimicking an odontogenic abscess: a case report and review of the literature.

Unlabelled: Inflammatory lesions, like periapical/odontogenic abscesses, are by far the most common pathologic condition of the jaws. Radiographically, these lesions commonly manifest as widening of periodontal ligament space, discontinuity of lamina dura and ill-defined periapical radiolucency. There are some rare disorders which could cause similar radiographic changes in the jaw bone.

Gross examination by the surgeon as an alternative to frozen section for assessment of adequacy of surgical margin in head and neck squamous cell carcinoma.

Background: The cost-effectiveness of the frozen section for assessment of margin in head and neck squamous cell carcinoma (HNSCC) is still contentious. The purpose of this study was to evaluate whether gross examination of margin is an alternative to frozen section.

Methods: It was a prospective observational study in 145 consecutive patients undergoing surgery for HNSCC.

Arecanut as an emerging etiology of oral cancers in India.

Arecanut (AN) usage is widespread in Asian countries, especially India and Taiwan. The incidence of oral cancer is increasing day by day, but there is no exponential increase with tobacco usage. Especially in the country like Taiwan where betel quid mostly do not contain tobacco, AN can be correlated with the increased incidence of cancer.

Oral squamous cell carcinoma arising in background of oral submucous fibrosis: a clinicopathologically distinct disease.

Background: Oral cancer is the most common cancer in Indian males and is the third most common cancer in Indian females. Tobacco, alcohol, areca nut, and human papillomavirus (HPV) are the common etiologic factors. Each of these agents follows a unique model of carcinogenesis that leads to a certain distinct presentation and behavior.

Mandibular metastasis in a patient with follicular carcinoma of thyroid.

Mandibular metastasis due to thyroid carcinoma is not very frequent and the cases described in the literature are few. Due to its bloodstream dissemination, most of them are a consequence of the follicular variant of thyroid carcinomas. We are presenting a case in which the metastatic lesion of mandible was detected before diagnosis of primary malignancy.

Utility of frozen section in assessment of margins and neck node metastases in patients undergoing surgery for carcinoma of the tongue.

Objective: The aims of this study are to evaluate the impact of frozen section in achieving adequate surgical margin and to study the accuracy of frozen section in detection of occult metastases.

Materials And Methods: This was a retrospective review of prospectively collected data of 877 patients with squamous cell carcinoma of the tongue who underwent surgery and intra-operative frozen section at our center from January 2007 to June 2010.

Results: Frozen section was found to have very high accuracy in assessment of margin as well nodal status.

Routine removal of the carotid sheath as part of neck dissection is unnecessary if grossly uninvolved as seen intra-operatively.

The aim of this research was to determine the pathologic invasion of the carotid sheath (CS) when found grossly uninvolved during surgery, in patients undergoing neck dissection for head and neck squamous cell carcinoma (HNSCC). A prospective study was undertaken in 70 consecutive patients with biopsy proven HNSCC, without prior history of any treatment, undergoing neck dissection, in whom the CS was found grossly uninvolved intra-operatively, were included. A total of 80 neck dissections were performed.
