Erosion of the long process of the incus with incomplete ossicular discontinuity in simple chronic otitis media: Should we reconstruct or leave it be?

OBJECTIVE: To determine whether patients with simple chronic otitis media and incomplete ossicular discontinuity should undergo ossicular reconstruction. DESIGN: Prospective, randomised surgical trial comparing no intervention with incus interposition over a 5-year period. SETTING: Tertiary referral hospital. PARTICIPANTS: Seventy-six participants with simple chronic otitis media and erosion of the long process of the incus but apparent good transmission throughout the ossicular chain as tested intra-operatively. Forty-four patients had partial erosion of the incus but still bony contact with the stapes head (Group A-Type I), and 32 had mainly connective tissue binding the incus and stapes (Group B-Type II). Each of these groups was randomised to either leaving the ossicular chain as it was (A1 and B1) or performing an incus interposition (A2 and B2). MAIN OUTCOME MEASURES: Average postoperative air-bone gap and the degree of ABG closure. A postoperative air-bone gap under 20 dB was considered a successful result. RESULTS: In group A, there was no significant difference between no intervention and incus interposition. In group B, patients in the no reconstruction subgroup had a significantly worse hearing result than the incus interposition subgroup (postoperative air-bone gap of 27.5 dB and 31% closure within 20 dB vs 15 dB and 75% closure). CONCLUSIONS: For Type I patients, the postoperative hearing results were similar for the reconstruction and no reconstruction groups. For Type II patients, the results clearly favour reconstruction.

Peritonsillar abscess: epidemiology and relationship with climate variations.

BACKGROUND: Peritonsillar abscess is the most common deep infection of the head and neck in young adults. It is considered a purulent complication of acute tonsillitis, but other mechanisms have been proposed. There is no consensus as to whether seasonality affects peritonsillar abscess incidence. METHODS: This observational, descriptive, retrospective study explored the epidemiology of peritonsillar abscess and its relationship with seasonality. The cases were selected from the emergency otolaryngology service of a tertiary hospital. RESULTS: The sample comprised 528 patients (42.61 per cent males, mean age = 26.63 years). A moderate positive correlation was found between peritonsillar abscess incidence and monthly average temperature. No associations were found with insolation, precipitation or humidity. CONCLUSION: In this sample, peritonsillar abscess was more likely to occur in warmer months. The findings corroborate the theory that peritonsillar abscess is not a direct complication of acute tonsillitis and may improve understanding of peritonsillar abscess aetiology.

A comparison of systemic inflammatory responses between immunocompetent and immunocompromised patients presenting with otorrhea due to chronic suppurative middle ear disease.

OBJECTIVES: To study the occurrence of fever and the behaviours of inflammatory blood markers (C-reactive protein - CRP and procalcitonin - PCT) during episodes of otorrhea due to uncomplicated chronic otitis media in immunocompetent and immunocompromised patients. DESIGN: Prospective study of patients presenting with otorrhea over a 36-month period. SETTING: All patients were treated at Bonsucesso General Hospital, a tertiary referral hospital in Rio de Janeiro, Brazil. PARTICIPANTS: A total of 84 participants, of which 50 were immunocompetent and 34 were immunocompromised. Immunocompetent patients had a total of 106 episodes of otorrhea, and immunocompromised patients had 117 episodes of otorrhea. MAIN OUTCOME MEASURES: Occurrence of fever (axillary temperature over 38(°) C) and elevation of C-reactive protein and procalcitonin levels above the normal ranges. RESULTS: In the immunocompetent group, the levels of procalcitonin were elevated in five of 106 episodes of otorrhea. The C-reactive protein levels were above the normal range in nine of 106 episodes, the same number of episodes in which fever was observed. In the immunocompromised group, procalcitonin was elevated in 38 of 117 episodes of otorrhea, C-reactive protein levels were abnormal in 40 episodes, and fever was detected in 37 episodes. Cases of otorrhea with systemic inflammatory response were significantly more common in immunocompromised patients with associated rhinosinusitis. CONCLUSIONS: Otorrhea due to uncomplicated chronic otitis media rarely causes a systemic inflammatory response in immunocompetent patients. Its occurrence in immunocompromised patients seems to be more related to concurrent rhinosinusitis than to the chronic middle ear inflammation itself.
