Temperature-controlled radiofrequency tonsil ablation for the treatment of halitosis

Coblation cryptolysis method in treatment of tonsil caseum-induced halitosis

PURPOSE

Halitosis, is a social problem affecting many patients seeking help from clinicians. Tonsil stones can cause halitosis and especially occur in crypts of palatine tonsils. Coblation cryptolysis is an alternative method for tonsil caseum treatment. The coblation technology includes passing a radiofrequency bipolar electrical current through a medium of normal saline which results in the production of a plasma field of sodium ions. In this study, our aim was to investigate the effectiveness of coblator cryptolysis treatment method in chronic caseous tonsillitis-induced halitosis.

METHODS

We included in our study 28 patients who underwent coblator cryptolysis surgery for halitosis due to chronic caseous tonsillitis. The efficacy of treatment and the presence of caseoma were evaluated with the Finkelstein test, organoleptic test and VAS before the procedure and at the 6th month control after the treatment was completed.

RESULTS

At the 6th month follow-up after the procedure (a single coblation cryptolysis) we found that 23 of the patients (82.1%) had no caseum. There was a statistically significant change in Finkelstein measurements before and after the procedure (p < 0.001). Organoleptic measurements demonstrated that 21 patients had no halitosis postoperatively and the mean organoleptic test score was calculated as 0.39 ± 0.79 after the procedure. The recovery was statistically significant (p < 0.001). The mean VAS score before coblation cryptolysis was 8.0 ± 1.33 (range 5-10). On the other hand 6 months after a single coblation cryptolysis session, the mean VAS score was 1.25 ± 1.78 (range: 0-6). This difference was statistically significant (p < 0.001).

CONCLUSIONS

Our results suggest that coblation crptolysis is an effective, safe, minimally invasive and practical alternative method in treatment of halitosis due to tonsil caseums. We did not observe any complication after the procedure.

Intracapsular tonsillectomy for keratosis pharyngeous: A pilot study of postoperative recovery and surgical efficacy

Our objective was to perform a pilot study comparing intracapsular radiofrequency ablation tonsillectomy with subcapsular tonsillectomy in adult patients with keratosis pharyngeous. Patients diagnosed with keratosis pharyngeous between December 2010 and February 2013 were randomized to undergo either intracapsular or subcapsular tonsillectomy using radiofrequency ablation. Postoperative pain scores and amount of pain medication taken were recorded for 2 weeks. A 6-month follow-up questionnaire was used to assess efficacy of the procedure. Twenty-two patients completed the initial 2-week questionnaire. Eighteen completed the 6-month follow-up questionnaire. The amount of pain medication consumed on postoperative days 8 (p = 0.0293), 9 (p = 0.0146), and 10 (p = 0.035) was significantly less in the intracapsular group. Risk of recurrence of tonsilloliths was significantly greater at the 6-month follow-up in the intracapsular cohort (p = 0.0291). Based on these findings, in patients undergoing tonsillectomy for keratosis pharyngeous, intracapsular radiofrequency ablation tonsillectomy may result in decreased pain medication consumption compared with subcapsular tonsillectomy. Intracapsular tonsillectomy, however, resulted in a higher rate of recurrence of tonsilloliths. The benefit of decreased pain medication may be offset by the greater likelihood for symptoms to recur. Larger studies are needed to confirm these findings.

Indications for tonsillectomy stratified by the level of evidence

Background: One of the most significant clinical trials, demonstrating the efficacy of tonsillectomy (TE) for recurrent throat infection in severely affected children, was published in 1984. This systematic review was undertaken to compile various indications for TE as suggested in the literature after 1984 and to stratify the papers according to the current concept of evidence-based medicine. Material and methods: A systematic Medline research was performed using the key word of "tonsillectomy" in combination with different filters such as "systematic reviews", "meta-analysis", "English", "German", and "from 1984/01/01 to 2015/05/31". Further research was performed in the Cochrane Database of Systematic Reviews, National Guideline Clearinghouse, Guidelines International Network and BMJ Clinical Evidence using the same key word. Finally, data from the "Trip Database" were researched for "tonsillectomy" and "indication" and "from: 1984 to: 2015" in combination with either "systematic review" or "meta-analysis" or "metaanalysis". Results: A total of 237 papers were retrieved but only 57 matched our inclusion criteria covering the following topics: peritonsillar abscess (3), guidelines (5), otitis media with effusion (5), psoriasis (3), PFAPA syndrome (6), evidence-based indications (5), renal diseases (7), sleep-related breathing disorders (11), and tonsillitis/pharyngitis (12), respectively. Conclusions: 1) The literature suggests, that TE is not indicated to treat otitis media with effusion. 2) It has been shown, that the PFAPA syndrome is self-limiting and responds well to steroid administration, at least in a considerable amount of children. The indication for TE therefore appears to be imbalanced but further research is required to clarify the value of surgery. 3) Abscesstonsillectomy as a routine is not justified and indicated only for cases not responding to other measures of treatment, evident complications, or with a significant history of tonsillitis. In particular, interval-tonsillectomy is not justified as a routine. 4) TE, with or without adenoidectomy, is efficacious to resolve sleep-related breathing disorders resulting from (adeno)tonsillar hypertrophy in children. However, the benefit is reduced by co-morbidities, such as obesity, and further research is required to identify prognostic factors for this subgroup of patients. Further research is indicated to clarify selection criteria not only for this subpopulation that may benefit from less invasive procedures such as tonsillotomy in the long-term. 5) Further trials are also indicated to evaluate the efficacy of TE on the clinical course in children with psoriasis guttata as well as on psoriasis vulgaris in adults, not responding to first-line therapy. 6) Conflicting results were reported concerning the role of TE in the concert to treat Ig-A nephropathy, mandating further clinical research. 7) Most importantly, randomized-controlled clinical trials with an adequate long-term follow-up are desirable to clarify the benefit of TE in patients with recurrent episodes of tonsillitis, with or without pharyngitis. Factors like age, spontaneous healing rate and postoperative quality of life have to be included when comparing TE with antibiotic therapy.

Halitosis and the Tonsils

Objective

Halitosis secondary to pathology of the palatine tonsils is considered airway (type 2) halitosis in the etiologic classification. Reports differ as to the proportion of objective halitosis complaints that have tonsillar etiology, with some giving this figure as 3%. Due to their immunologic role, even healthy tonsils usually possess some subclinical inflammation. The tonsil crypt system is also the most ideal environment for anaerobic bacterial activity in the upper respiratory tract. Tonsillar halitosis is thought to occur mainly because of chronic caseous tonsillitis and tonsillolithiasis (tonsil stones). Tonsillectomy and various cryptolysis techniques are reported to improve halitosis in such cases. In this article, diagnostic methods and evidence for interventions are reviewed.

Data Source

Medline search.

Review Methods

Studies reporting the efficacy of any intervention (medical or surgical) on tonsillar halitosis were included, whether halitosis was the focus or one of several measures.

Conclusions

There are insufficient high-quality studies on this topic. Improved methodology, for example, use of control groups and utilization of more accurate halitosis detection/quantification techniques, are required.

Implications for Practice

Lack of evidence currently prevents firm conclusions, but the following is recommended: (1) Use reliable methods for halitosis diagnosis and confirmation of tonsillar etiology. Initial treatment such as tongue scraping is useful to rule out oral halitosis. (2) Tonsillar procedures are contraindicated in: subjective halitosis, non-tonsillar etiology, or if medical management resolves halitosis. (3) Where indicated and where facilities permit, less invasive techniques such as laser cryptolysis may be preferable to tonsillectomy in adults, potentially avoiding general anesthetic and the higher risk associated with tonsillectomy in this group.

Effectiveness of radiofrequency cryptolysis for the treatment of halitosis due to caseums

OBJECTIVE

To evaluate the effectiveness of radiofrequency (RF) cryptolysis for caseum-induced halitosis.

STUDY DESIGN

Clinical retrospective study.

SETTING

Otorhinolaryngology Head and Neck Surgery Department of Konya Training and Research Hospital in Turkey.

SUBJECTS AND METHODS

Thirty-four patients with caseum-induced halitosis were included. Eight were male (23.5%) and 26 were female (76.5%). Their mean age was 28.29 ± 9.3 (range: 17-48) years. The mean duration of complaint of halitosis before RF cryptolysis was 53.41 ± 42.6 months (range: 6-182 months). The Finkelstein test, organoleptic measurements, and visual analog scale (VAS) were performed before and 12 months after RF cryptolysis.

RESULTS

Before RF cryptolysis, all patients had a positive Finkelstein's test result, organoleptic measurements revealed that three (8.82%) had serious halitosis, 24 (70.58%) had average halitosis, and seven (20.58%) had mild halitosis, and the mean VAS score was 6.82 ± 1.45. The follow-up period after RF cryptolysis was 12 months. After the single RF cryptolysis session, 26 patients (76.47%) were negative for Finkelstein's test, organoleptic assessments revealed that 26 (76.47%), six (17.64%), and two (5.88%) showed complete, partial, and no recovery, respectively, (p<0.001), and the mean VAS score was significantly better at 1.88 ± 2.5 (p<0.001). Thirty-two patients (94.1%) exhibited a decrease in VAS score.

CONCLUSION

RF cryptolysis is a cost-effective, safe, and easily applicable modality for the treatment of halitosis due to caseums in the crypts of the palatine tonsils.
