BackgroundTo assess whether the techniques of percutaneous needle electrolysis (PNE) and deep dry needling (DDN) used on trigger points (TrP) of lateral pterygoid muscle (LPM) can significantly reduce pain and improve function in patients with myofascial pain syndrome (MPS) compared to a control group treated with a sham needling procedure (SNP).Material and MethodsSixty patients diagnosed with MPS in the LPM were selected and randomly assigned to one of three groups. The PNE group received electrolysis to the LPM via transcutaneous puncture. The DDN group received a deep puncture to the TrP without the introduction of any substance. In the SNP group, pressure was applied to the skin without penetration. Procedures were performed once per week for 3 consecutive weeks. Clinical evaluation was performed before treatment, and on days 28, 42 and 70 after treatment.ResultsStatistically significant differences (p<0.01) were measured for the PNE and DDN groups with respect to pain reduction at rest, during chewing, and for maximum interincisal opening (MIO). Values for the PNE group showed significantly earlier improvement. Differences for PNE and DDN groups with respect to SNP group were significant (p<0.05) up to day 70. Evaluation of efficacy as reported by the patient and observer was better for PNE and DDN groups. No adverse events were observed for either of the techniques.ConclusionsPNE and DDN of the LPM showed greater pain reduction efficacy and improved MIO compared to SNP. Improvement was noted earlier in the PNE group than in the DDN group.

BackgroundTo determine whether deep dry needling (DDN) of trigger points (TPs) in the lateral pterygoid muscle (LPM) would significantly reduce pain and improve function, compared with methocarbamol/paracetamol medication.Material and MethodsForty-eight patients with chronic myofascial pain located in the LPM were selected and randomly assigned to one of two groups (DDN test group, n=24; drug-treated control group, n=24). The test group received three applications of needling of the LPM once per week for three weeks, while control group patients were given two tablets of a methocarbamol/paracetamol combination every six hours for three weeks. Assessments were carried out pretreatment, 2 and 8 weeks after finishing the treatment.ResultsA statistically significant difference (p<0.05) was detected for both groups with respect to pain reduction at rest and with mastication, but the DDN test group had significantly better levels of pain reduction. Moreover, statistically significant differences (p<0.05) up to day 70 in the test group were seen with respect to maximum mouth opening, laterality and protrusion movements compared with pretreatment values. Pain reduction in the test group was greater as a function of pain intensity at baseline. The evaluation of efficacy as assessed both by patients/investigators was better for the test group. 41% of the patients receiving the combination drug treatment described unpleasant side effects (mostly drowsiness).ConclusionsDDN of TPs in the LPM showed better efficacy in reducing pain and improving maximum mouth opening, laterality, and protrusion movements compared with methocarbamol/paracetamol treatment. No adverse events were observed with respect to DDN.

Objectives: To compare the effectiveness of a daily home-based facial exercise therapy with a supervised rehabilitation technique for the treatment of postoperative facial dysfunction in patients undergoing conventional superficial parotidectomy. Design: Prospective, randomized trial, controlled. Setting: Surgery and Rehabilitation Units, university hospital. Subjects: Consecutive patients (n=79, mean age 48 years) who underwent superficial parotidectomy with facial nerve dissection were randomly divided into two groups. Intervention: Control group (CG) were given a daily homework manual to perform ordinary postoperative facial mimic exercises autonomously in front of the mirror at home. Experimental group (EG) patients with moderate-severe paresis received supervised rehabilitation therapy that consisted in weekly sessions with facial exercises and massages and performed daily facial exercises at home. EG patients with slight paresis were instructed to undertake self-massage and mirror exercises. Main outcome measures: Postoperative dysfunction of facial nerve and branches was quantified measuring the prevalence, magnitude and duration of paresis by the House-Brackmann Facial Nerve Grading System up to 12th months. Results: Facial paresis incidence at 1st week was 77.2%, being the marginal-mandibular nerve the most affected (64.5%). No statistically significant differences were found at any time of the study when comparing the frequency, magnitude and duration of paresis between EG and CG and among patients who had presented moderate-severe paresis. In the absence of intraoperative nerve injury, complete recovery of facial mobility was observed within 12 months, regardless of treatment group. Conclusion: Rehabilitation therapy and mirror facial exercises performed autonomously at home were equally effective for postoperative functional recovery.
Abstract. The present study aimed to describe the techniques used and the results obtained with the infrahyoid flap for the reconstruction of medium-sized oropharyngeal defects following resection for advanced squamous cell cancer. During a period of 1 year, six patients with oropharyngeal defects were reconstructed using the infrahyoid flap. The tumor characteristics, location and size of the defect, resective and reconstructive techniques employed and the complications and outcomes of the speech and swallowing functions, as identified in the follow-up visits every 3 months, were evaluated. All flaps were performed simultaneously in association with tumoral excision and ipsilateral supraomohyoid neck dissection. The mean size of the skin paddle was 7.0x3.5 cm. The donor site was primarily sutured. The postoperative course was uneventful and all flaps were viable. One case of marginal skin paddle loss occurred without affecting the survival of the flap. Five patients received postoperative radiotherapy and one patient received concurrent postoperative chemotherapy. During the follow-up period (mean, 63 months), all patients showed excellent oral swallowing. Speech was excellent in five patients and in one patient speech was classified as good. The aesthetic results of the cervical donor site were good. Based on the present case report and the literature review, the infrahyoid flap is a simple and safe procedure for the reconstruction of the oropharynx, with a high success rate, minimal donor site morbidity and good aesthetic and functional results. The infrahyoid flap is a valid surgical option that may be considered in selected oncological patients undergoing reconstruction of medium-size oropharyngeal defects.
