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

Abstract

Objective:

To report the frequency of the types of maxillary tumours and the resulting post-surgical defects

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.

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.
