First Case

Nitrous oxide, a cryogenic gas, may be abused as an inhalant for its euphoric properties. If inhaled, nitrous oxide may cause frostbite to the oral cavity and upper aerodigestive tract, with possible airway compromise due to edema. In this article we describe what is, to the best of our knowledge, the first case of intentional inhalation of nitrous oxide from an automotive nitrous oxide canister and discuss the management and mechanism of the patient's injury.

Abstract Transoral laser microsurgery (TLM) is an important option in the treatment plan for tumors of the oral cavity, oropharynx, larynx, and hypopharynx. For properly selected patients, TLM provides equivalent oncologic outcomes when compared to traditional therapies, while improving the functional aspects of postoperative speech, voice and swallowing.

Background: Mandibular tori are a rare cause of difficult direct visualization of the upper aerodigestive tract. In the setting of aerodigestive tract pathology necessitating direct visualization, removal of mandibular tori may be required to facilitate treatment. Methods: In the first case, large bilateral symmetric mandibular tori were removed to facilitate access to the anterior commissure and removal of a T1 glottic squamous cell carcinoma (SCC). In the second case, large bilateral mandibular tori were removed to access a markedly exophytic SCC in the right vallecula. Subsequently, the tumor was removed with robotic assistance with excellent exposure. Results: Both patients were free of recurrence at last follow-up. Conclusion: Mandibular tori are an uncommon cause of difficult direct laryngoscopy. In situations that require direct visualization of the anterior commissure or base of tongue for diagnosis and management of lesions, surgical removal of the tori may be required as in the cases presented here.

<p class="abstract"><strong>Background:</strong> Upper aerodigestive tract malignancies constitute approximately 4% of all malignancies. These include cancers of the various sites of the upper aerodigestive tract where malignant lesions can be found such as the nasal cavity, paranasal sinuses, nasopharynx, oral cavity and it’s sub-sites, oropharynx, larynx and hypopharynx. Malignancies of these sites are found to be common in people from lower socio-economic strata. Tobacco and alcohol are considered as risk factors for it’s development.</p><p class="abstract"><strong>Methods:</strong> A cross-sectional study was conducted in the outpatient section of Department of ENT, at Chamarajanagar Institute of Medical Sciences and Hospital, Chamarajanagar, India, for a period of 1 years 10 months from October 2014 to July 2016. During the study period, 100 cases that were diagnosed as having upper aerodigestive tract malignancy by histopathology were included in the study group. The aim of this study is to determine the epidemiology, clinical features and anatomical site-wise distribution of malignancy in the study group.  </p><p class="abstract"><strong>Results:</strong> Oral cavity was the commonest site where malignancy developed in the upper aerodigestive tract followed by the larynx. Malignant disease was more common in males and in the elderly.

Histology Report

A 4-month-old boy presented with a cystic swelling at the floor of the mouth causing acute airway compromise. The only previous history of note, was a tongue tie release at 3 days old. CT scan suggested a dermoid cyst with extensive floor of mouth abscess. He had an excision of the cyst and drainage of the superimposed abscess and made a good recovery. The histology report revealed a dermoid cyst which is a rare diagnosis in a child, particularly within the oral cavity. Early treatment is required to remove these lesions especially when they cause airway compromise or swallowing difficulties. This is the first case to our knowledge which suggests tongue tie release procedures causes a predisposition to the development of dermoid cysts in the oral cavity.

Abstract Background UADT neoplasms is a heterogenous diseases entity which includes primaries arising from nose and paranasal sinuses, nasopharynx, oral cavity, oropharynx, hypopharynx and larynx. Squamous cell carcinoma is the predominant histologic type. The likelihood of having nodal diseases at presentation may have a wide range depending the size and site of the primary tumor with significantly higher risk for patients with nasopharyngeal primaries and advanced T stage of other sub-sites of upper aerodigestive tract. Chances of having multiple and bilateral nodes also have direct correlation with the size of the primary tumors. Positive cervical nodal status is one of the most reliable prognostic factors which drops cure rate significantly. It is also responsible for treatment failure, local recurrence and reduction of survival rate and its a reliable indicator of development of distant metastasis. The pattern of distribution of nodal involvement is different for each site. Thorough study of distribution of most likely involved lymph node levels for each sub site helps to customize the neck treatment accordingly by avoiding radical treatments with significant functional and aesthetic morbidity. Objective To define prevalence and pattern of nodal and distant metastasis of UADT-SCC patients at the time of diagnosis. Method Institution based retrospective cross sectional medical chart review of patients from September 2015- September 2020 was conducted. 259 patients who fulfilled the inclusion criteria were selected using systematic random sampling technique and data was collected using questioner. Result A total of 259 medical records were reviewed. Mean age at presentation is 44.8. Male to female ratio is 2.6:1. Prevalence of positive nodal diseases at presentation is 71%. Site specific analysis showed 50% of nose and PNS, 86.1% nasopharyngeal, 73.2% oral cavity, 70% oropharyngeal, 66.7% hypo-pharyngeal and 57.2% laryngeal primaries had positive nodal diseases at presentation. Majority of late presentations had positive nodal diseases (p<0.05).Nasopharynx is the commonest site of primary tumor (30.5%). It is also the commonest site with higher percentage of positive nodal diseases (86.1%).Most patients had advanced stage at presentation (cTNM stage III and IV- 88.1%). Distant metastasis was found in 10.8% of patients and had strong association with T stage (p<0.05). Conclusion and recommendation This study concluded that majority of patients fall in the age group of 31 to 40 with male predominance of 2.6 to 1. Late presentation is a rule since most patients with UADT-SCC has advanced disease at presentation with significant nodal neck diseases. Nasopharynx is the commonest site of primary tumor for both males and females. It's also the commonest site of primaries with higher percentage of positive nodal diseases at presentation. Chances of having positive cervical nodal disease at presentation were very high in patients with advanced T diseases. Pattern of metastasis of most sites are inline with the current accepted knowledge of practice. Research designs with better strength should be used to study the clinicopathologic behavior of UADT-SCC both nation wide and in region specific setups. Institutional cancer registry should be improved and made easily accessible to researchers.Patient’s medical records should be complete. Policies on preventive measures and screening tools should be designed.Health seeking behavior of the community should be improved.Referral system should be made easy for patients with suspected cases.

Pathologic Findings

Granular cell myoblastoma (Abrikossoff's tumor), although certainly a rare, almost always benign lesion, is being encountered with increasing frequency in areas of particular interest to the otolaryngologist or surgeon in the upper aerodigestive tract. Although such lesions have been found frequently in the oral cavity and larynx, only one case has been reported of such a lesion originating in the esophagus. The detailed clinical and pathologic findings of three additional patients with esophageal lesions are described. Conservative surgical removal of granular cell myoblastoma may be preferable to endoscopic dilatation.
