Abstract:
The efficacy of surgery in controlling infection in 272 tympanomastoidectomy procedures for chronic otitis media (COM) was assessed by means of a four-point rating scale that incorporated both symptoms and signs, such as the presence or absence of otorrhea and granulation tissue. Of the 272 procedures, 170 were performed for COM with cholesteatoma and 102 were for active COM with granulation tissue but no cholesteatoma. Forty-seven percent were primary procedures, and 53% were revisions. Minimum follow-up was 12 months for all cases, with a mean of 30 months. Adequate control of infection occurred in 248 (91%) of the 272 cases. Of the 24 cases (9%) that developed persistent infection, 10 were controlled with a combination of oral and topical antibiotics and/or delayed skin grafting in the office. Thus overall satisfactory control of infection was achieved in 258 of 272 cases (95%). The outcome was influenced by the diagnostic category of COM: COM with cholesteatoma did significantly better than COM with granulation tissue (P = 0.02). The outcome was not influenced by the following variables: primary versus revision surgery, canal wall-up versus canal wall-down surgery, and extent of disease. The results suggest that active COM with granulation tissue may be more difficult to control than COM with cholesteatoma.
Insights
Surgery effectively controlled chronic otitis media (COM) infection in 95% of cases. Tympanomastoidectomy outcomes were better for COM with cholesteatoma compared to COM with granulation tissue.
Area of Science:
- Otolaryngology
- Infectious Disease Management
- Surgical Efficacy Assessment
Background:
- Chronic otitis media (COM) presents a significant challenge in otologic surgery.
- Controlling infection is paramount for successful surgical outcomes in COM patients.
- Tympanomastoidectomy is a common surgical procedure for managing COM.
Purpose of the Study:
- To evaluate the efficacy of tympanomastoidectomy in controlling infection in patients with chronic otitis media.
- To compare surgical outcomes between COM with cholesteatoma and COM with granulation tissue.
- To identify factors influencing the success of infection control after surgery.
Main Methods:
- A retrospective analysis of 272 tympanomastoidectomy procedures for COM.
- Infection control was assessed using a four-point rating scale including symptoms and signs like otorrhea and granulation tissue.
- Patients were categorized by COM type (cholesteatoma vs. granulation tissue), procedure type (primary vs. revision), and surgical approach (canal wall-up vs. canal wall-down).
- Minimum follow-up was 12 months, with a mean of 30 months.
Main Results:
- Overall, adequate infection control was achieved in 91% (248/272) of cases, with satisfactory control in 95% (258/272) after additional medical management.
- COM with cholesteatoma had significantly better infection control outcomes than COM with granulation tissue (P = 0.02).
- Persistent infection occurred in 9% (24/272) of cases, with 10 cases successfully managed non-surgically.
- Procedure type, surgical approach, and extent of disease did not significantly influence outcomes.
Conclusions:
- Tympanomastoidectomy is a highly effective surgical treatment for controlling infection in chronic otitis media.
- Active COM with granulation tissue presents a greater challenge for infection control compared to COM with cholesteatoma.
- While surgery provides a high rate of infection control, adjunctive medical therapies can further improve outcomes in challenging cases.
