TYPES OF MAXILLARY TUMOURS AND THE RESULTING POST-SURGICAL DEFECTS IN PATIENTS AT A TEACHING HOSPITAL

Objective: to report the frequency of the types of maxillary tumours and the resulting post-surgical defects based on aramany classification. study design, duration and setting: this descriptive study was done during the period of 5 years (2005-11) at the otorhinolaryngology & head and neck surgery unit, khyber teaching hospital peshawar. methodology: a pre-structured proforma was used for data collection. data recorded included patients' age, gender, type of maxillary tumour, type of maxillectomy and approach for resection, post-surgical defect based on aramany classification for acquired maxillary defects, neck dissection, radiotherapy, and prosthetic rehabilitation. data were computed for descriptive statistics including frequencies, percentages and mean values. results: patients (n=53) had a male to female ratio of 1.7. some 26.4% patients belonged to the age group of 31-40 years. maxillectomy was done for inverted papilloma, a benign tumour in 1.9% patients as compared to malignant squamous cell carcinoma in 66% patients. maxillary resection for fibrous dysplasia was done in 3.8% patients who were relatively younger.. maxillectomy in all cases was performed using weber-fergusson incision approach. surgical resection resulted in armanay class i defect in 73.58% patients. in 92.5% patients a surgical obturator was provided to patients at the time of maxillectomy. conclusion: maxillectomy was mainly performed for resecting malignant tumours using weber-fergusson incision with the fitting of immediate surgical obturator. the resulting defect was mainly aramany class i defects
