Infratemporal fossa abscess caused by acute sinusitis, without other predisposing factors, is very rarely reported. We present such a case in a 78-year-old woman who was treated successfully with surgical drainage and antibiotics. She presented with a 10-day history of swelling and pain on the right side of her face. Physical examination revealed swelling on the right mandible area up to the zygomatic arch and the presence of mucopurulent rhinorrhea in the right nasal cavity without abnormal dental findings. Computed tomography revealed a right infratemporal fossa abscess and ipsilateral maxillary sinusitis connected through a defect on the posterior wall of the maxillary sinus. Drainage procedure was performed by navigation-guided endoscopic sinus surgery and intravenous antibiotics were administered. During a four months follow-up period, there was no sign of recurrence. Infratemporal fossa abscess can develop from acute sinusitis without predisposing factors, including dental infection. Surgical drainage along with intravenous antibiotics can lead to successful treatment in such cases.

OBJECTIVES: Mastoid obliteration is used to obliterate the mastoid cavity following a mastoidectomy or to prevent the formation of a retraction pocket. This study evaluated the effectiveness of beta-tricalcium phosphate and polyphosphate (beta-TPP) for mastoid obliteration in middle ear surgeries in prospective human and animal studies. METHODS: Twenty patients with chronic otitis media underwent mastoid obliteration using beta-TPP after a intact canal wall mastoidectomy or simple mastoidectomy. The clinical data were prospectively evaluated including: the diagnosis, temporal bone computed tomography (TBCT), otoscopic findings, pure tone audiogram, and complications. In the animal experiment, beta-TPP was applied into the right bulla in five rats, and the opposite bulla was used as the control in the non-obliterated state. The skulls of five other rats were drilled out and the holes were obliterated with beta-TPP. TBCT were obtained at 3, 6, and 9 months after the obliteration and histologic analysis was done at 3 and 9 months after surgery. RESULTS: In the human study, fourteen TBCTs were obtained at 12 months after the surgery. All demonstrated no bone resorption in the obliterated mastoids. Among the 15 cases displaying retracted tympanic membranes preoperatively, 11 showed no retraction, 2 showed retraction postoperatively, 1 was lost to follow-up and 1 was a case of postoperative wound infection. Among 20 cases, one case developed a postoperative infection that necessitated a second operation. Sixteen underwent ossiculoplasty; hearing improvements were obtained in 15 cases and 1 case showed decreased hearing. In the animal study, new bone formation without significant bone resorption in the radiologic and histologic findings were noted in both the skull and bulla groups. CONCLUSION: Although beta-TPP is a foreign material having the possibility of infection, mastoid obliteration with it can be a treatment option in middle ear surgeries to prevent retraction pockets or the recurrence of diseases.
