The frequency of occult cervical metastasis in oral squamous cell carcinoma patients - A cross sectional study.

OBJECTIVE: To determine the frequency of occult cervical metastasis in oral squamous cell carcinoma patients. METHODS: This cross sectional study was conducted in the department of maxillofacial surgery, Mayo Hospital, Lahore from July 31st, 2015 to January 31st, 2016 on 100 patients of oral Squamous Cell Carcinoma (SCC) having clinically and radiologically negative nodes. Prophylactic functional neck dissection was done in each patient and was sent to the pathology lab for evaluation of any occult metastasis. RESULTS: Overall frequency of occult cervical metastasis was found to be 27%. In 41(41 %) specimens of SCC of tongue, 13(31.7%) had occult metastasis. In Alveolar mucosa occult metastasis was found in 4(20 %) out of 20(20 %) patients. In SCC of buccal mucosa occult metastasis was found in 10(29.4%) out of 34(34 %) patients. In SCC of lip no occult metastasis was detected. CONCLUSIONS: Within the boundaries of the present study, it is concluded that occult cervical metastasis was most frequent in cases of SCC tongue, whereas no occult cervical metastasis detected in SCC of lip.

Correction of hypoplastic mandible in non-syndromic temporomandibular joint ankylosis patients with distraction osteogenesis in Mayo Hospital Lahore: A descriptive study.

OBJECTIVE: To evaluate the efficacy of simultaneous gap arthroplasty and distraction osteogenesis in the treatment of non-syndromic temporomandibular joint ankylosis patients with hypoplastic mandible. METHODS: The descriptive prospective study was conducted at the Department of Oral and Maxillofacial Surgery, King Edward Medical University / Mayo Hospital, Lahore, Pakistan, from January to December, 2016, and comprised patients having temporomandibular joint ankylosis with hypoplastic mandible. Interpositional gap arthoplasty, osteotomy and application of distractor were done in all the patients. Preoperative and post operative data was collected and analysed us in gSPSS12 . RESULTS: Of the 63 patients, 29(46%) were males with a mean age of 18.48±2.32 years and 34(54%) were females with a mean age of 16.41±3.21 years. Overall mean age was 17.37±3 years (range: 9- 24 years). Of the total, 20(32%) patients were given a single distractor on ramus per side, while 43(68%) were given double distractors (ramus + body) per side. Lengthening was achieved in all (100%) patients both in ramus and body. Only 1(1.6%) patient presented with a complication during the distraction period, and the case was successfully managed surgically. CONCLUSIONS: Distraction osteogenesis is a promising treatment option for the correction of mandibular deformities as a result of temporomandibular joint ankylosis.
