The aim of the study is to give an idea about true incidence and most common location of fallopian canal dehiscence and to identify predictive factors associated with fallopian canal dehiscence based on preoperative and peroperative clinical correlates so as to facilitate preemptive prediction of the condition. The study design pertains to a prospective study. The setting of the study was tertiary referral hospital and a total of 146 patients underwent radical and modifi ed radical mastoidectomy as primary procedure between Jan. 2003 to Dec. 2004. The site of dehiscence and associated pre-operative and per-operative fi ndings were noted. Our results showed the incidence of fallopian canal dehiscence among cases undergoing radical and modifi ed radical mastoidectomy was 82/1000 per year. Around 66.6% dehiscence was located in tympanic segment. The preoperative factors signifi cantly associated with the fallopian canal dehiscence (p< 0.05) were Aural polyp, Extra-cranial complications, Cholesteatoma and Facial palsy. Per-operative fi ndings were Cholesteatoma, All ossicles necrosed except stapes footplate and Lateral semicircular canal fi stula.

The aim of this randomized control trial, performed at a tertiary referral hospital, was to compare the therapeutic effectiveness of two novel treatment modalities, oral rifampicin and submucosal placentrex injection, in randomly selected patients of primary atrophic rhinitis regarding objective, subjective and histopathological improvement. Patients treated with oral rifampicin showed most promising results regarding objective, subjective and histopathological improvement with maximum disease-free interval on regular follow-up as compared to submucosal placentrex injections.

Odontogenic myxoma of maxilla is a very rare occurrence. It is a slow growing benign, locally malignant tumor notorious for recurrence. Hereby we present a case of recurrent odontogenic myxoma of the maxilla in a 32-year-old male managed surgically by partial maxillectomy. The diagnostic and operative dilemmas encountered while managing the case are discussed in detail.

Chondrosarcoma, the most malignant cartilageneous tumor, constitute only 4% of non-epithelial tumours of the nasal cavity, paranasal sinuses and nasopharynx, making it one of the rarest malignancies. 1,3 Here we present a case of Grade 1 chondrosarcoma involving nose, maxillary sinus, ethmoids and sphenoid sinus managed surgically by wide excision. 12 months follow-up reveled no recurrence or complication.

Chronic osteomyelitis of frontal sinus is a rare complication of recurrent sinusitis. The pent-up secretions in the sinus may result in pressure necrosis of the containing wall of frontal sinus resulting in persistently discharging fi stula. Here we present a case of chronic osteomyelitis of frontal sinus with persistent midline fi stula over forehead in a 30 year old male managed surgically by osteoplastic fl ap procedure and frontal sinus obliteration with abdominal fat.

dacryocystitis or otherwise, is better dealt with the endoscopic approach for its direct exposure and minimal discomfort to the patient. This avoids external scar and seeding at external incision site.6 CONCLUSIONIn all cases of lacrimal sac pathology, one needs to keep a clinical diagnosis of rhinosporidiosis in mind. Although dacryocystectomy has been described as the treatment of choice, an endonasal DCR with excision of the lesion, followed by postoperative dapsone therapy for a year, could suffice. However, long term follow up and more number of case studies are necessary to establish efficacy of this modality of management.
