Lingual Abscess: Predisposing Factors, Pathophysiology, Clinical Manifestations, Diagnosis, and Management

Lingual abscess is a rare disorder, and current knowledge regarding clinical manifestations and treatment modalities has not been well established. This study presented 6 cases of lingual abscess patients between January 2012 and December 2017. There were three men and three women. Median age was 54 years. Odynophagia and local pain were the common presenting symptoms. Local trauma was the main predisposing factor of anterior abscess, while lingual tonsillitis or infected thyroglossal cyst was the predisposing factor of posterior abscess. An impending airway obstruction was identified in two patients, requiring tracheostomy. All patients achieved an excellent outcome with a combination of surgical drainage and proper antibiotics as well as using proper investigation for detecting unusual areas of lingual abscess. According to the data from the study's results and review of the relevant literature, an abscess located at the anterior two-thirds of the tongue is easy to diagnose while the posterior one-third of the tongue abscess is relative difficulty. Using contrast-enhanced computed tomography increases diagnostic accuracy, especially on the tongue base and deep space infection. The management strategies include (1) protecting the airway, (2) draining the abscess by needle aspiration or surgery, and (3) administering antibiotics early. Our series showed a superiority of surgical drainage when the patients present with marked tissue edema, deep loculated infection, and airway obstruction.

Microscopic approach for repairing nasal septal perforations using bilateral advancement flaps

Abstract

Background

Septal perforations consist in an anatomic defect of the mucosal, cartilaginous and/or bone tissues of the nasal septum. A huge variety of approaches and techniques for nasal perforation repair have been reported.

Methodology/principal

Between January 2008 and January 2017, 38 patients were treated for nasal septal perforation in Department of Otorhinolaryngology Head and Neck Surgery, Fundación Jiménez Díaz University Hospital, Madrid, Spain. A novel approach is presented based on microscope. Septal perforation closure was performed with endonasal bilateral advancement flaps-established technique and autologous cartilage and muscle temporal fascia grafts. We performed a retrospective review of closure rates and complications.

Results

A postoperative follow-up of at least 12 months was performed in 37 patients. The mean size of perforation was 1.33 cm. After the withdrawal of the silicone splints, perforations were completely closed in all cases. However, during the follow-up, four patients resulted in a reperforation, so our closure rate was 89.19%. For all cases, symptoms related to septal defect were solved. Only one case was reported of local infections that was resolved with antibiotics in a few days.

Conclusions

Microscopic approach of septal perforation closure using bilateral advancement flaps can be an affordable technique with a high percent of success and low rate of complications.

Impact of age on elderly patients with oral cancer

Abstract

Introduction

In this study we have tried to analyze the impact of age on various clinico-pathological parameters, treatment completion and subsequent survival in older patients.

Materials and methods

This is a retrospective analysis of 140 elderly (> 65 years) patients of oral cancer operated between January 2012 and December 2013. The patients were divided into two groups based upon their age that ≤ 70 years and > 70 years.Association of distribution of various clinico-pathological factors between different groups was assessed by using Chi-square test. Survival analysis was done using Kaplan Meir analysis. Univariate and multivariate analysis were performed.

Results

The two groups had similar distribution of various clinico-pathological factors. Disease free survival for the group ≤ 70 and > 70 years was 37.6 months and 36.4 months (p < 0.594). 13.5% and 7.8% patients > 70 years and ≤ 70 years were either advised or received sub-optimal adjuvant therapy (p < 0.002).

Conclusion

There is no difference distribution of various clinico-pathological factors and survival in patients of oral cancer ≤ 70 and > 70 years of age. Age did not affect survival. Majority of patients could complete the adjuvant therapy advised. Still, significantly more number of patients > 70 years could not receive/complete appropriate adjuvant therapy. Thus treatment needs to be tailored keeping in mind the individual's performance status and the co-morbidities.

Tranexamic acid and post-tonsillectomy hemorrhage: propensity score and instrumental variable analyses

Abstract

Purpose

Although post-tonsillectomy hemorrhage occurs rarely, it can be life-threatening. Previous studies showed that tranexamic acid (TXA) had insignificant association with the rate of post-tonsillectomy hemorrhage, but those findings were limited by small sample sizes. The purpose of this study was to examine the effectiveness of TXA in preventing post-tonsillectomy hemorrhage using nationwide database.

Methods

Data of a retrospective cohort of 117,598 patients from 750 hospitals, who had undergone tonsillectomy between 2010 and 2016, were drawn from the Diagnosis Procedure Combination database in Japan and studied.

Results

Propensity score-matched analysis showed no significant differences in proportions of reoperation or blood transfusion after tonsillectomy between the treatment (TXA from the day of tonsillectomy) and control groups (1.50% vs. 1.47%, p = 0.64). Instrumental variable analysis also showed no significant differences (odds ratio, 0.98; 95% confidence interval, 0.86–1.13; p = 0.82). Higher proportions of reoperation or blood transfusion were significantly associated with male sex, older age, emergency hospitalization, prolonged anesthesia, and medium hospital volume (annual number of tonsillectomies).

Conclusions

Administration of TXA from the day of tonsillectomy is not associated with reduction in reoperation or blood transfusion rates.

In vivo Raman spectroscopic characteristics of different sites of the oral mucosa in healthy volunteers

Abstract

Objectives

Investigate the biochemistry of in vivo healthy oral tissues through Raman spectroscopy. We aimed to characterize the biochemical features of healthy condition in oral subsites (buccal mucosa, lip, tongue, and gingiva) of healthy subjects. More specifically, we investigated Raman spectral characteristics and biochemical content of in vivo healthy tissues on Brazilian population. This characterization can be used to better define normal tissue and improve the detection of oral premalignant conditions in future studies.

Materials and methods

For spectroscopic analysis a Raman spectrometer (Kaiser Optical Systems imaging spectrograph Holospec, f / 1.8i-NIR) coupled with a laser 785 nm, 60 mW was used. Raman measurements were obtained by means of an optical fiber (EMVision fiber optic probe) coupled between the laser and the spectrometer. Three spectra per site were acquired from the lip, buccal mucosa, tongue, and gingiva of ten healthy volunteers. This resulted in 30 spectra per oral sub-site and in total 120 spectra.

Results

We report detailed biochemical information on these subsites and their relative composition based on deconvolution studies of their spectra. Finally, we also report classification efficiency of 61, 83, 41, and 93% for buccal, gingiva, lip, and tongue respectively after applying multivariate statistical tools.

Conclusions

We quantitated the contribution of various biochemicals in terms of percentage, and this will enable comparison not only across anatomical sites but also across studies. Raman spectroscopy can rapidly probe tissue biochemistry of healthy oral regions. Moreover, the study suggests the possibility of using Raman spectroscopy combined with signal processing and multivariate analysis methods to differentiate the oral sites in healthy conditions and compare with pathological conditions in future studies.

Clinical relevance

The spectral characterization of the healthy condition of oral tissues by a noninvasive, label-free, and real-time analytical techniques is important to create a spectral reference for future diagnosis of pathological conditions.
