A comparison of the efficacy of narrow band imaging and contact endoscopy in an early diagnosis of squamous malignancies of the upper aerodigestive tract.

Background: This study aims to compare the efficacy of narrow band imaging (NBI) endoscopy and contact endoscopy in early diagnosis of squamous malignancies of upper aerodigestive tract. Methods: This study was of 18 months duration, sample size 50, and carried out at tertiary care hospital. The patients were subjected initially to NBI endoscopy followed by contact endoscopy. Thereafter, the lesion was biopsied and subjected to histopathological examination as is done routinely. The images obtained were analyzed based on criteria proposed by earlier studies and compared with histopathological examination as gold standard. Results: The sensitivity, specificity, and negative predictive values of NBI in early diagnosis of squamous malignancies of upper aerodigestive tract were high and better than contact endoscopy. Conclusion: Endoscopic NBI is a noninvasive and promising tool used for in vivo differentiation between malignant and nonmalignant lesions of upper aerodigestive tract by using morphology of mucosal capillaries and is more efficacious than contact endoscopy. It can be employed as part of routine ENT examination in outpatient departments; however, it has got a learning curve associated with it.

Post Surgical Outcomes in Paediatric Adenotonsillar Hypertrophy with Obstructive Sleep Apnea: Subjective and Objective Evaluation.

The aim of the study was to determine the post surgical outcomes in pediatric adenotonsillar hypertrophy with OSA using portable polysomnography (PSG), OSA 18 Questionnaire and Quality of life (QoL) scores. Secondly to correlate the subjective outcomes with objective scores of polysomonography. A prospective, single-arm, nonrandomized, single center study was performed at a tertiary care centre on children aged 3-12 years (n = 30) with adenoid hypertrophy/ tonsillar hypertrophy/adenotonsillar hypertrophy and symptoms suggestive of OSA. All subjects underwent appropriate surgical intervention. A portable PSG and OSA 18 questionnaire evaluation was performed pre surgery and 06 weeks post surgery to assess objective and clinical assessment for OSA. The mean age of children enrolled in the study was 8.68 ± 3 years. The mean pre treatment AHI was 12.56 ± 13.16 which improved to 1.72 ± 1.53 post surgery and was statistically significant (p < 0.05, Wilcoxon signed rank test). There was a statistically significant improvement in other PSG indices such as RDI and ODI post surgery also. The mean total symptom score (TSS) and QoL score also showed a statistically significant improvement post treatment (p < 0.05). However there was no correlation between the PSG and OSA 18 questionnaire scores pre and post surgery. Children with OSA like symptoms can undergo a portable polysomnography pre and post surgery to demonstrate severity of OSA and objectively monitor improvement in OSA post treatment. In the absence of availability of PSG, OSA 18 questionnaire is a suitable alternative to monitor disease severity and outcomes. Further studies may plan to include impact of paediatric OSA on other function such as the cardiac, dentition & malocclusion and neurocognitive function.

Evaluation of swallowing in patients with T3/T4 oral squamous cell carcinoma.

Background: Follow-up of patients treated for head and neck cancer is an important part of the overall treatment. Oral cancers are one of the leading causes of dysphagia. Swallowing dysfunction occurs owing to the disease itself, its predisposing factors, and the treatment. This study aims to evaluate swallowing dysfunction in patients with oral cavity cancers. Methods: This prospective study was carried out in a tertiary care hospital institution. Thirty patients with T3, T4 oral cancers were evaluated using institutional dysphagia score and fiber optic endoscopic evaluation of swallowing (FEES) (Penetration-Aspiration Scale, Yale Pharyngeal Residue Scale) before treatment, after surgery, and after adjuvant therapy. Results: Advanced-stage tumor, larger resections, and adjuvant therapy are risk factors for dysphagia postoperatively. Although the dysphagia score is our institutional score, the results are promising, that is, 10 % of patients having symptoms at baseline evaluation, which increased to 60% and 70% after surgery and adjuvant radiotherapy respectively. Our study findings of the Penetration Aspiration Scale are 13% aspiration rate at the baseline evaluation, which increased to 57% and 73% after surgery and after adjuvant radiotherapy, respectively, and these results are consistent with those of other report studies. The Vallecular Residual Scale showed that there was a significant association between three different timelines and demonstrated dysphagia among study subjects. Conclusion: Subjective and objective assessment of swallowing dysfunction before and after the treatment of head and neck cancers is underreported and underrecognized. Most of the patients in our study had significant swallowing impairment after treatment. FEES is a very effective procedure to diagnose dysphagia and will help in incorporating better preventative and rehabilitative measures.

The Role of Empirical Treatment with Proton Pump Inhibitor as a Diagnostic Tool in Laryngopharyngeal Reflux.

The presentations of laryngopharyngeal reflux (LPR) are diverse and include chronic hoarseness, sensation of foreign body in the throat, sore throat etc. 24 h pH monitoring considered the gold standard of investigation for LPR is costly, cumbersome and not readily available at all centers. Empirical trial of Proton pump inhibitor (PPI) as a diagnostic tool after assessment by Reflux Symptom Index (RSI) and Reflux Findings Score (RFS) is a cheaper, simple and readily available alternative. The objectives of the study were to determine clinical manifestations in patients presenting with LPR and to evaluate the role of empirical treatment with PPI as a diagnostic tool in LPR. 100 patients were divided into experimental group (RSI ≥ 13 and RFS ≥ 7) and control group (RSI < 13 and RFS < 7). Omeprazole trial was given to experimental group and assessed for RSI and RFS at 04 and 08 weeks. Statistical analysis was done within the group and between the groups. (1) The response rate to Omeprazole at 04 and 08 weeks interval (RSI<13 and/or RFS<7) was 60% and 76% respectively. (2) The response to Omeprazole given to the experimental group with RSI≥13 and RFS≥7 was significant at 04 weeks and 08 weeks duration (P<0.0001). RSI and RFS are good clinical tools to assess and diagnose patients with Laryngopharyngeal reflux. Based on the clinical diagnosis an empirical trial of a proton pump inhibitor (PPI) can be given to patients for duration of 02 months resulting in a good response.

Utilization of PET/CT Scan in Head and Neck Carcinoma: A Tertiary Care Hospital Experience.

Objective: PET/CT scan has been increasingly used in assessment of Head and Neck cancer prior to treatment for evaluation and for surveillance. In this study we aim to assess the utilization of PET/CT scan at a tertiary care hospital. Methods: Retrospectively data was reviewed of all patients of Head and Neck cancer who underwent PET/CT scan for workup or for follow-up between July 2018 and December 2019. PET/CT scan done in the pre-treatment assessment and post-treatment surveillance were analyzed for its utility. Results: A total of 145 patients were included. The main indication for pre-treatment PET/CT scan was loco-regionally advanced disease (62 of 90 patients, 68.8%). No specific indication was noted in 19 patients (21%). A significant change in treatment decision was seen in pre-treatment patients based on M stage following a PET/CT scan. However, no change was noted on the basis of T or N stage. In the post-treatment surveillance there was a significant correlation of type of recurrence with clinical assessment and indication for PET/CT scan. 37 out of 87 patients (42.5%) underwent PET/CT scan for no specific reason, of which, 07 patients (18.9%) were detected to have distant metastasis. Conclusion: Role of PET/CT in the pre-treatment assessment is very limited and maybe confined to advanced local or regional disease. Post-treatment surveillance with PET/CT scan has a promising role and must be done as a baseline during 1st follow up at 03 months in all patients who have advanced disease and have undergone multi-modality treatment for the same.

Approach to Management of Cerebrospinal Fluid Rhinorrhea: Institutional Based Protocol.

The role of otolaryngologist in the management of CSF rhinorrhea is expanding. It is prudent to evaluate all cases of CSF leak, understand the etiological causes and formalize a working approach to management of such cases to yield better outcome. A retrospective descriptive study of 39 cases of proven CSF rhinorrhea treated at a tertiary care center between January 2014 to August 2019. The data retrieved were analyzed for age, gender, weight, etiology, recurrence of the disease, history of meningitis, nasal or neurosurgical intervention in past, imaging inform of CT and MR cisternography as and when required. This was aimed at understanding the various etiological types of CSF rhinorrhea and work out a management approach. The patients with skullbase tumors who presented with CSF Rhinorrhea were excluded from the study sample. There were 18 cases of spontaneous CSF rhinorrhea and 20 cases of traumatic CSF rhinorrhea. The mean BMI of spontaneous gp was 32.9 ± 2.46 kg/m2 while in traumatic group was 25.7 ± 2.94 kg/m2 and difference was statistically significant. None of the spontaneous CSF rhinorrhea cases showed features of raised ICP preoperatively either clinically or on imaging except empty sella in 14 of 18 cases. 6 of 18 cases of spontaneous category while 01 of 20 cases in traumatic had recurrence and the recurrence rate was significantly (p < 0.05) higher in spontaneous group. In traumatic group 7 were iatrogenic, 8 were occult traumatic and rest were acute traumatic. 4 of traumatic and 1 spontaneous group had history of meningitis and the incidence was 12.8% in our study group. Early identification and localization of CSF fistula is necessary to reduce morbidity and mortality associated with it. Risk of meningitis is high in CSF rhinorrhea especially in traumatic group. The etiology of CSF rhinorrhea has a bearing on the management and spontaneous CSF rhinorrhea has higher rate of recurrence.

Role of subjective visual vertical in patients with posterior canal benign paroxysmal positional vertigo as a prognostic marker after canalith repositioning maneuver.

Objective: To study the potential role of subjective visual vertical (SVV) as a prognostic marker for canalith repositioning maneuver (CRM) in patients with posterior canal benign paroxysmal positional vertigo (PC-BPPV) for the Indian population. Methods: SVV was examined in 30 patients with PC-BPPV before and after canalith repositioning maneuver and after complete resolution of PC-BPPV. Study parameters included the mean of 10 angular tilt readings and direction of deviation, which were compared before and after CRM and following complete resolution of PC-BPPV. Results: The angle of SVV tilt was greater and deviated towards the affected ear before CRM in all patients, which decreased significantly shortly after CRM and continued to decrease after complete resolution of PC-BPPV (p < 0.0001). Conclusions: SVV can be used to test utricular dysfunction in PC-BPPV. The angle of tilt improves in response to CRM, which may be used as a prognostic marker in patients with PC-BPPV receiving CRM.

Role of Octreotide in Conservative Management of Chyle Leak Post Neck Dissection in Cases of Head Neck Cancer: A Retrospective Analysis.

Chyle leak is a dreadful complication in patients undergoing neck dissections. Octreotide has been used in the management of chyle leak post neck dissections in head and neck cancer patients. Currently there is no consensus and practice guidelines on the same. (1) To study the role of octreotide in early cessation of post neck dissection chyle leak. (2) To study incidence of intra-operative and post-operative CL, its relation to the extent of nodal disease and neck dissection, prior radiotherapy. Retrospective analysis of 16 patients out of 529 neck dissection over a period of 03 years between Jan 2016 and Dec 2019 who developed post-operative chyle leak. All patients who had post-operative chyle leak were administered octreotide. Time taken for chyle leak to stop was primary outcome. Secondary outcomes were duration of hospitalization post-operatively, incidence of intra-operative and post-operative chyle leak, its relation to the extent of nodal disease, prior radiotherapy and type of neck dissection. 59 of 529 neck dissections (11.15%) were noted to have intra-operative chyle leak. 16 of 529 neck dissections (3.02%) developed post-operative chyle leak. On applying chi square test, prior multimodality and N plus neck were found to be significant risk factors in developing postoperative chyle leak. Considering only RT versus no RT in prior multimodality treated group, the difference was insignificant. Onset of chyle leak varied from 1 to 5 post-op day (mean 2.68 days). 15 (93.75%) patients responded to octreotide. Chyle leak resolved between 3 and 10 days (mean 5.18 days) and octreotide was given for 5-12 days (mean-7.18 days). Overall duration of hospitalization ranged from 09 to 18 days (mean 12.18 days). 01 patient (6.25%) had to be re-explored due to high volume leak despite using octreotide. Adverse effects of octreotide were minimal and tolerable. Octreotide is effective in reducing the duration of chyle leak, hospital stay and need for surgical intervention. It may be considered as suitable adjunct to conservative measures in the management for post-operative chyle leak.

Versatility and Reliability of Islanded Pedicled Nasolabial Flap in Head and Neck Cancer Reconstruction.

OBJECTIVES: Reconstruction of head and neck cancer ablative defects is challenging. A modification of the nasolabial flap (islanded pedicled nasolabial flap [ipNLF]) is an easy and reliable option for reconstruction of small- to medium-sized defects of the head and neck, especially in resource-constrained and high-volume centers. STUDY DESIGN AND METHODS: We present the retrospective analysis of 27 consecutive patients reconstructed with ipNLF at two high-volume cancer centers, Homi Bhabha Cancer Hospital, Varanasi, India; and Army Hospital Research and Referral, New Delhi, India. The functional outcomes measured were duration of weaning of feeding and tracheotomy tubes and speech assessment (speech intelligible rating score [SIR]) postsurgery. Complications assessed were flap loss, orocutaneous fistula, donor site wound dehiscence, oral incompetence, and angle of mouth deviation. RESULTS: The most common ablative defect was of the oral cavity (22 patients), followed by the oropharynx (4 patients) and hypopharynx (1 patient). The mean operating time for flap harvesting and insetting was 57.7 minutes. The mean durations for postoperative feeding tube and tracheotomy removal were 10 and 5 days, respectively. Twenty-four subjects had SIR scores of I or II. None of the subjects had flap loss, orocutaneous fistula, or donor site wound dehiscence. Twenty-five subjects had no oral incompetence, and 26 subjects had no or minimal angle of mouth deviation. CONCLUSION: This is the largest series of ipNLF to date and emphasizes the versatility, reliability, reproducibility and excellent functional and acceptable cosmetic outcomes of this flap for the reconstruction of judiciously chosen head and neck ablative defects. LEVEL OF EVIDENCE: 2C Laryngoscope, 130: 1967-1972, 2020.

Use of the facial artery-based cutaneous island flap (melo-labial flap) for reconstruction of the neopharynx following total laryngectomy: a novel technique.

Reconstruction of neopharynx after total laryngectomy is a challenging task. Various locoregional flaps like pectoralis major myocutaneos/ latismus dorsi flaps and free flaps have their own limitations and advantages. To overcome this, we used facial artery-based cutaneous island flap (melo-labial flap) for reconstruction of the neopharynx following total laryngectomy (DK Gupta technique). This flap is thin, pliable, without any gravitational pull and without any risk of anastomosis failure and hence has advantage of both locoregional and free flaps and eliminates the limitations of both. It is simple, reproducible and reliable reconstructive option for neopharynx. We present a case report, review of literature and this novel technique for an excellent outcome and recommend to use it as the new workhorse of neopharyngeal reconstruction.

An unusual case of recurrent post aural abscess.

Preauricular sinus (PAS) is a common congenital anomaly which is usually asymptomatic and noted on routine otolaryngological examination which requires no treatment. Patients presenting with discharge, recurrent infections and preauricular abscess will require management with antibiotics and surgical extirpation of the sinus tract. We present a rare case of a PAS presenting as a recurrent postaural abscess.
