Comparative Study of Outcome of Type I Tympanoplasty in Chronic Otitis Media Active Mucosal Disease (Wet Ear) Versus Chronic Otitis Media Inactive Mucosal Disease (Dry Ear)

A Comparative Study of Outcomes and Quality of Life in Canal Wall up Mastoidectomies and Canal Wall down Mastoidectomies

Abstract

Chronic Otitis Media (COM) of the squamosal type was primarily managed by performing a canal wall down mastoidectomy; however, the latter era otolaryngologist envisioned benefits in preserving the posterior canal wall. Our primary objective was to assess the disease specific quality of life following canal wall up (CWU) mastoidectomy and canal wall down (CWD) mastoidectomy surgery after a 6 month post-operative period. A prospective observational study was done from September 2017 to August 2018 where the charts of 380 patients from Christian Medical College, Vellore were reviewed. Details of patients above 18 years who had undergone the above surgeries for COM active squamosal disease from the period of January 2014 to December 2016; and had their post-operative follow up (average of 16 months) during the period of study were looked at. The CWU group had a significantly better disease-specific quality of life in the symptoms subscale than the CWD group (p value < 0.01). The CWU group showed a significant air-bone gap closure to 23.3 dB as compared to 27.7 dB in CWD (p value = 0.005). The recurrence rates were 4.5% (9 cases) in the CWU group and 3.9% (7 cases) in the CWD group, which was not statistically significant. Both CWU and CWD methods of mastoidectomy for COM squamosal type give comparable outcomes in terms of recurrence with the CWU group having a better disease-specific quality of life after surgery.

Comparison of Endoscopic Cartilage Myringoplasty in Dry and Wet Ears With Chronic Suppurative Otitis Media

OBJECTIVES

This study compared the rate of graft success, as well as hearing improvement and dry ear time between dry ears and wet ears with otomycosis or without otomycosis in patients with chronic suppurative otitis media (CSOM) after endoscopic cartilage myringoplasty.

METHODS

This retrospective study was conducted in a tertiary hospital in Shanghai. In total, 83 patients with CSOM (43 with dry ears and 40 with wet ears) were included. Among the 40 patients with CSOM and wet ears, 25 exhibited otomycosis. All patients underwent endoscopic myringoplasty, and perforations were repaired using tragal cartilage with a single-sided perichondrium. Patients were followed up for at least 6 months. Pure-tone hearing was examined preoperatively and at 3 months postoperatively. The graft uptake rate, hearing improvement, and dry ear time were compared between the groups.

RESULTS

The graft success rate did not differ significantly between the dry-ear and wet-ear groups (95.35% and 90.00%, respectively). Furthermore, the graft success rate also did not differ significantly between patients with wet ears and otomycosis and those with wet ears without otomycosis (92.00% and 86.67%, respectively). Hearing gain did not differ significantly between the dry-ear and wet-ear groups. No significant difference in hearing gain was also found in patients with wet ears with or without otomycosis. However, the time to dry ear was significantly longer in the wet-ear group than in the dry-ear group.

CONCLUSION

Patients with CSOM and wet ears required more time to achieve a completely healthy status. However, the graft success rate and hearing improvement were not affected by a wet middle ear and otomycosis. Thus, endoscopic myringoplasty using tragus cartilage is an effective treatment for refractory CSOM in patients with wet ears and otomycosis.

Is It Wise to Wait for Ear to Become Dry in Indian Scenario?

Tympanoplasty is the standard and well-established procedure for closure of tympanic membrane perforations. Tympanoplasty in wet ear is still a topic of debate among ENT surgeons. This study discusses the balance between wait and watch policy and early intervention in wet ear. It also compares the rate of graft uptake and hearing improvement in Type I tympanoplasty in dry and wet ears. This is a hospital based, observational, descriptive and comparative study. Total 246 patients enrolled in the study. Two groups were created with 123 patients in each group. One included dry ears and another included wet ears. All patients had mucosal type of chronic otitis media. They all underwent Type I tympanoplasty. Graft uptake rate and hearing was compared between both groups. The overall success rate (graft uptake) was 91.06% (224). The success rate in dry ear group was 93.50% (115) and in wet ear group it was 88.62% (109). This study concluded that there is no added advantage of drying the ear rather the delay in treatment increases morbidity and drop outs in Indian scenario.

A comparative study of endoscopic cartilage myringoplasty used to treat wet and dry ears with mucosal-type chronic otitis media

OBJECTIVE

The outcomes of dry and wet ears were compared following endoscopic cartilage myringoplasty performed to treat chronic tympanic membrane perforations in patients with mucosal chronic otitis media.

METHODS

Patients with chronic perforations, and with mucosal chronic otitis media with or without discharge, were recruited; all underwent endoscopic cartilage myringoplasty. The graft success rate and hearing gain were evaluated at six months post-operatively.

RESULTS

The graft success rates were 85.9 per cent (67 out of 78) in dry ears and 86.2 per cent (25 out of 29) in wet ears; the difference was not significant (p = 0.583). Among the 29 wet ears, the graft success rates were 100 per cent in 11 ears with mucoid discharge and 77.8 per cent in the 18 patients with mucopurulent otorrhoea.

CONCLUSION

The wet or dry status of ears in patients with chronic perforations with mucosal chronic otitis media did not affect graft success rate or hearing gain after endoscopic cartilage myringoplasty. However, ears with mucopurulent discharge were associated with increased failure rates and graft collapse, whereas ears with mucoid discharge were associated with higher graft success rates.

Outcome of surgery for chronic suppurative otitis media with resistant Pseudomonas aeruginosa

OBJECTIVE

To assess the effectiveness of surgical treatment of active chronic suppurative otitis media (CSOM) with ciprofloxacin-resistant Pseudomonas aeruginosa (P. aeruginosa) that failed comprehensive local and systemic treatment.

STUDY DESIGN

Retrospective case review.

SETTING

Tertiary referral center.

PATIENTS

Eleven patients with ciprofloxacin-resistant P. aeruginosa CSOM that remained active despite comprehensive local and systemic treatment. All patients were operated by a single surgeon between February 2016 and July 2019 INTERVENTION(S): Tympanoplasty alone was performed in seven cases and accompanied by mastoidectomy in the other four cases.

MAIN OUTCOME MEASURE(S)

Resolution of infection and tympanic graft take on otoscopy. The secondary outcome measure is hearing.

RESULTS

Tympanic graft take was successful and the infectious process was resolved in 8 out of the 11 cases, yielding a success rate of 73%. The average follow-up was 20 months. No surgical complications occurred.

CONCLUSIONS

Tympanoplasty, with or without mastoidectomy, is safe and yields acceptable anatomical and functional success rates when intensive local and systemic treatment fails to stop the purulent discharge.
