Outcome of Treatment in Verrucous Carcinoma of Oral Cavity: A Tertiary Rural Hospital Experience

Verrucous carcinoma of oral cavity is a highly well differentiated variant of squamous cell carcinoma with a low potential for invasion and metastasis. It is prevalent in the tobacco quid chewing population in our region. In this observational study, we reviewed the medical case records of 58 patients treated for oral verrucous carcinoma staged T2 to T4a. All patients underwent wide excision of tumour which included marginal mandibulectomy in 22 and hemimandibulectomy in 23 patients along with neck dissection saving the accessory nerve and internal jugular vein. 5 patients were found to have bone involvement along the alveolar sockets. 11 patients had other associated premalignant lesions in oral cavity. Only 2 patients had lymph node metastasis without extra nodal spread in submandibular region. With a mean follow up of 6 years and minimum follow up of 1 year, 3 patients had local recurrence. All these 3 patients had bone involvement and 2 of them had lymph node metastasis on histopathological examination. 3 patients who had associated premalignant lesions developed second primary in oral cavity after 3 years. In our experience, verrucous carcinoma has good prognosis when treated by surgery. Bone involvement along alveolar sockets and associated oral premalignant lesions adversely affect the outcome. There was no difference in the outcome between selective and modified radical neck dissection. Therefore selective neck dissection (supraomohyoid) would be adequate in treating these patients. Adjuvant radiotherapy can be reserved for T4a lesions or for positive margins.

Role of Buccal Pad of Fat in Reconstruction of the Buccal Mucosa Defects

Carcinoma buccal mucosa is the most common oral cavity cancer in India. Following excision of these lesions the defects can be reconstructed using various reconstructive techniques. Buccal pad of fat has been successfully used in the reconstruction of small palatal defects and in the closure of the oro antral fistula. This study aims at evaluating the role of buccal pad of fat in reconstruction of defects following excision of the small to medium premalignant lesions and T1-T2 malignant lesions of buccal mucosa. This study has 20 patients who presented between January 2013 and January 2015, with biopsy proven premalignant lesions and early malignant lesions in the buccal mucosa. The lesions were excised and reconstructed with buccal pad of fat. Patients were followed up for a period of 3 months, in this period were evaluated for flap epithelisation, postoperative complications like flap necrosis and infection and also the functional outcomes of the flap. In our study complete epithelisation of the flap was seen in all patients. Wound dehiscence was seen in three patients with larger defetcs(>5 cm). None of our patients had any post operative morbidity. This flap is therefore an excellent reconstruction technique for small to medium buccal mucosa defects as it is convenient, reliable, fast, has rich vascularity, easy accessibility, fewer complications and minimal or no donor site morbidity.

Cervical chondrosarcoma- rare malignancy: a case report

To highlight an uncommon bone malignancy, which presented to our institute, as a neck swelling in the supraclavicular region. A 30 year old man presented with history of swelling on the left side of neck since 1 year and numbness of left upper limb since 6 months. Magnetic Resonance Imaging of the Cervical spine & MR Angiography showed a 7.4 × 4.6 cm expansile lesion involving transverse process of C5-C7 vertebrae. As the tumour was found to be deep to the phrenic nerve & brachial plexus, a dual approach was used, anteriorly via neck incision and posteriorly via the spine. The tumour was resected & iliac crest grafted along with stabilization of the cervical spine. Patient is disease free and the cervical spine stabilized with normal movements at two and half years follow up. We need to consider tumour arising from the vertebra as a differential diagnosis for any deep seated hard neck swelling in the supraclavicular region. Even low grade malignancy of this region when resected en-bloc will have a good prognosis.

Island pectoralis major myocutaneous flap: an Indian perspective

The aim of this study is to conceive a method of raising an island PMMC flap, so as to circumvent its drawbacks of bulk, flap length and the difficulty of developing this flap in female patients. And to consider island PMMC flap as a viable reconstructive option in head and neck surgeries, especially in peripheral centres. Ours is an experimental case series. The study was done at Sri Devaraj URS Medical college, Tamaka, Kolar. Between 2009 and 2010, head and neck reconstruction was performed using this method in 20 patients who had oral cancer (18), carcinoma supraglottis (1) and mucoepidermoid carcinoma parotid (1). The patients age ranged from 16 to 75 years, and there were 15 women and 5 men. Nineteen of our patients underwent primary surgery and one patient was operated for residual disease. In (16) patient, island pmmc flap was used for intra oral closure. In (4) patients the flap was spiraled for providing skin cover. Four patients developed complications. Three were minor complications of margin necrosis and wound dehiscence, which were managed conservatively. One patient developed orocutaneous fistula, which required secondary suturing. None of our patients had a total necrosis of the flap. Island PMMC flap is still a very useful and viable option for reconstruction in head and neck surgeries, especially in lateral gingivo buccal tumours and other head and neck tumours. In institutions where microvascular expertise is not available, island PMMC flap can be an alternative with results comparable to that of free tissue transfer.

A case of retropharyngeal Lipoma

Lipomas are one of the most common benign mesenchymal tumors in the body. Usually asymptomatic, they rarely warrant treatment unless they attain enormous size causing cosmetic deformity or pressure effects. Head and neck region is an uncommon site, retropharyngeal space being one of the rarest. Lipomas in this region can produce pressure symptoms demanding surgical excision.This is a case report of retropharyngeal lipoma, extending from skull base to the clavicle. Though tumor was present for 20 yrs it exhibited rapid growth over a period of 2-3 yrs causing respiratory obstruction, dysphagia & dysphonia. Clinically the entire laryngopharynx, trachea and carotid sheath were pushed anteriorly. On imaging, it showed classical features of a lipomatous mass. Patient underwent complete excision which presented a surgical challenge to surgeon and the anaesthetist from intubation to extubation.
